EP1510492B1 - Method for testing an elevator and elevator - Google Patents

Description

The invention relates to a method for checking elevator systems. Furthermore, the invention relates to an elevator installation, which is provided with a car, an elevator drive and an elevator control, which comprises a memory, and to which a display and control unit is coupled.

Lift systems must be checked after installation or extensive repair work. In particular, after the installation of the elevator installation commissioning is required in which many parameters must be set and a comprehensive and detailed examination of the individual components of the elevator system is performed. A series of process steps must be performed after all mechanical parts and all electrical components have been installed in order to put the system in a condition that allows normal operation. Among the necessary steps of a commissioning include a review of the mechanical and electrical requirements, activation of the electrical components, a review of the drive, the configuration of shaft information to determine the position and speed of the elevator car and the configuration of an elevator control and a device for Measurement of cabin load and communication interfaces. A good example of such a method, which is considered to be the closest prior art, is known from EP 0366097 A1.

After commissioning, the lift system must undergo an acceptance test. The acceptance test is carried out by a person authorized to carry out this activity, the acceptance tester, and involves a series of tests which must be carried out before the transfer of the lift equipment to the customer in order to determine whether the installation meets the intended specification fulfilled or whether the legally prescribed guidelines and standards are fulfilled or whether deficiencies exist and, if so, what these consist.

The acceptance test is concluded with the preparation of an acceptance report, which records the results of the tests carried out. According to the statutory provisions, the acceptance tester must personally answer the result of the acceptance test. Various certificates, such as a certificate of conformity, a completion agreement or a certificate of acceptance, must be issued and signed in person. The acceptance tester therefore has a personal interest in reliably obtaining an overview of all the requirements to be checked, including the legal standards and the relevance of the various results of the acceptance test, at the location of the lift installation. The documentation that is customary today does not make it easy to gain this overview in individual cases, especially as the documentation often contains information for an elevator type, but also contains cross-references to other sources, such as legal standards and specific data sheets for specific components , which must be evaluated separately.

The concrete steps of commissioning and / or acceptance testing of an elevator installation are generally dependent on the specific configuration of the elevator installation. In particular, the type or series of the elevator installation and the design of the elevator installation play a decisive role in terms of size, performance and comfort.

Commissioning and acceptance tests according to a standard pattern are complex for the person checking and provide many occasions to make mistakes that are sometimes overlooked. This is justified in particular by the fact that each elevator installation is designed individually and therefore requires an individualized check. Even the installation of elevator systems of the same series in buildings with different building parameters require different measures for commissioning and acceptance testing. Further developments of elevator systems require a constant adaptation of the measures for commissioning and acceptance testing. These developments are contained in a number of supplementary documents, so that the commissioning engineer and the acceptance tester make a large number of individual decisions that depend on the specific configuration of the elevator, for example type of elevator, type of drive used, type of safety brake used, design of the elevator with regard to the height of the shaft, the maximum load to be transported, the intended maximum speed of the car, etc., must be determined in order to determine the appropriate measures during commissioning and during the acceptance test. With the large number of selection decisions, many errors can be made, in particular by overlooking details or omitting individual measures.

In addition, a large number of measured values must be recorded, whereby further measures must be selected depending on the measured values, in particular in the case of deviations between actual values and setpoints. The setpoints depend in part on several parameters of the elevator configuration and must be determined for each individual case. For example, the effect of a brake on the type of brake and also depends on other installation parameters, such as the mass and the intended maximum speed of the elevator car or the design of the guide rails for the car from.

In order to carry out a commissioning or an acceptance test, extensive documentation is required which the commissioning engineer or acceptance tester must carry with him if he always wants to be equipped for all possible plant types and configurations of a plant type. If he only wants to carry the absolutely necessary documents of a specific elevator installation with him, he must make a targeted selection, whereby documents can easily be forgotten or wrong documents can be selected.

The object of the invention is to specify a method for checking an elevator installation, in which errors are avoided or at least reduced by a person checking. Furthermore, such a method should allow a comfortable and reliable acceptance of a lift system. Furthermore, the invention has for its object to provide an elevator system.

This object is solved by the features of claims 1 and 21st

The invention is based on the idea that the information about the special elevator installation is already partly available during the installation or that parameters relevant for the commissioning or acceptance test are known to the manufacturer of the elevator installation. The manufacturer of the elevator installation knows in each case the necessary steps, which are necessary for the commissioning and the acceptance test of an elevator installation.

Therefore, it is proposed according to the invention that when checking an elevator installation, all necessary steps are determined on the basis of configuration data of the elevator installation in the elevator control. These configuration data are stored for this purpose in a memory of the elevator installation. Based on the determined steps, a verification program is then created, which processes the steps in a predetermined sequence. In this case, the steps are displayed by the display and control unit, with inputs required for the individual steps of parameters of the elevator installation via the display and control unit are entered.

The type of check depends on a selected operating mode. The selected operating mode also depends on the creation of the verification program. For example, a different inspection program is required for commissioning an elevator installation than for the acceptance test of an elevator installation already in operation. The configuration data of the elevator installation are stored in a memory and identify the elevator installation and its configuration in such a way that these configuration data result clearly identify all steps to be taken for verification purposes. After specification of the configuration data, the course of the verification program can be specified. The verification program includes a menu control that guides through the necessary steps of verification. The tests, inspections, tests, input of parameters, etc. required for the execution of the steps are displayed to the person checking via the display and control unit, whereby required inputs are entered via the display and control unit. The steps required for a review may also include a request to inspect components of the elevator installation. Prompts may also be included for entering parameters, for example of the building, or for precisely setting components for normal operation. The configuration data may include setpoints of parameters that are displayed on the display and control unit. Moreover, a step may include a request to record an actual value of a parameter and to enter it via the display and operating unit, so that the actual value can be compared with the associated setpoint value.

The embodiment according to the invention always carries out a complete inspection of the elevator installation. Based on the configuration data, an efficient verification program is created which guides the reviewer through the review in the correct order with all necessary details. The step-by-step processing prevents the omission of steps. Because the verification program does not allow you to proceed to the next step until the current step has been successfully completed. Due to the configuration data, a search for optional equipment of the elevator installation can be omitted. Any further developments of components or new legal regulations are taken into account in the configuration data and are therefore the basis for the creation of the verification program. The inspecting person does not have to carry extensive documentation to be equipped for all the different configurations of elevator installations. From the configuration data, all required Parameters that must be checked, adjusted or entered during a check.

Advantageous embodiments of the invention are specified in claims 2 to 20 and 22 to 28.

In an advantageous embodiment of the invention, the verification program is processed by a processor of the elevator control. The elevator control usually has the necessary computing power, so that the verification program can be started on the processor of the elevator control. However, it is also possible to use a processor arranged in the display and operating unit for processing the checking program. This allows the check to be carried out without affecting the computing power in the elevator control. For this purpose, the configuration data is transmitted to the display and control unit, so that the verification program can be created there. However, the verification program can also be created in the elevator control and then transmitted to the processor of the display and control unit to be processed there. This is particularly necessary if the computing power in the elevator control is limited or required for other necessary processes during commissioning. In addition, a mobile display and control unit in the review of advantage, since the examiner must be in many different positions in the elevator system or in the elevator shaft to perform the review.

In an advantageous embodiment, according to the invention, the components which are installed in the elevator installation are initialized according to the invention. This can be done by switching on the elevator system or by a manual activation of the components by the person checking. Through the initialization, it is possible to detect the extent of the installed components and to derive therefrom the configuration data of the elevator installation and to record and store it in the memory of the elevator installation. Preferably For example, the configuration data of the elevator installation may include an identification number and / or a list of all components of the elevator installation, which must be taken into account during the check. This allows individual determination of all the steps required for the check, whereby a clear assignment is made by the identification number and confusions are excluded. Further, the review also checks only the components that were actually installed in the elevator system, eliminating the need to find out if optional components are installed.

In an advantageous embodiment of the invention, an identity check of the person checking is carried out before the start of the commissioning, wherein the identity check is carried out by entering codes or by means of a chip card or by means of biometric sensors. This excludes commissioning and / or acceptance testing by unauthorized persons.

In a further advantageous embodiment of the invention, a mobile display and control unit is connected to the elevator installation, which includes its own memory into which the verification program based on the configuration data is transmitted. Thus, the computing power of the elevator system is not affected by the review. In addition, a standard presence of a processor in the display and control unit can be used to perform the verification, which allows a menu system based on known operating systems to be used.

In a further advantageous embodiment of the invention, the configuration data of the elevator installation are detected and stored during manufacture. Since the manufacturer of the elevator installation knows all the relevant components which have to be checked or adjusted depending on the operating mode, he can determine the configuration data of the elevator installation during the construction of an elevator installation and store these preferably in the memory of the elevator control. However, he can also store the configuration data on a data carrier or in a service center where they can be retrieved when needed. When stored on a data carrier or in the service center, there is the advantage that any further developments of the components or changes in the legal provisions can be incorporated into the configuration data and thus prevents the configuration data stored in the memory of the elevator installation from becoming obsolete. For example, an obsolescence of the configuration data may be prevented by updating the configuration data via a communication link with the service center.

Likewise, it is advantageously possible to capture and store the configuration data of the elevator installation after installation of the elevator installation. In this case, a detection program is started, which queries the configuration data of components of the elevator system. In this embodiment, it is advantageous if individual configurations that have resulted in the installation of the elevator system, are taken into account.

In an advantageous embodiment of the invention, a commissioning mode is selected as the operating mode. All the necessary commissioning steps are determined on the basis of the configuration data and stored in a memory of the elevator installation. The commissioning steps are used to create a commissioning sequence program that is started by a commissioning engineer. This commissioning procedure programs the commissioning steps in a predetermined order, wherein the commissioning steps are displayed by the display and control unit and required inputs of parameters of the elevator installation via the display and control unit are entered. By selecting the commissioning mode, the commissioning sequence program can be created, which is specifically tailored to the necessary measures for commissioning. Due to the special configuration data of the elevator installation, a commissioning procedure program is created which is tailored to the specific requirements of the elevator installation. The commissioning engineer therefore only has to display the information displayed on the display and operating unit Process steps without having to look up certain parameters of the elevator installation.

Advantageously, the commissioning steps include a request to connect or to test components of the elevator installation, a request to enter parameters or to make adjustments to components.

In an advantageous embodiment of the invention, a commissioning protocol is created after the completion of all commissioning steps. This gives the commissioning engineer and all interested persons an overview of the checks and adjustments made during commissioning. Advantageously, the commissioning protocol can be stored in the memory of the elevator installation and / or the memory of the display and control unit. This allows a later call-up of the commissioning protocol, so that the correctness of the commissioning can also be checked at a later date. Advantageously, after a complete and successful startup, a startup status can be set, which is stored in the memory of the elevator installation. This commissioning status allows a quick query about the implementation of the commissioning, without having to evaluate the commissioning protocol. In addition, it can be provided to transmit the commissioning protocol via a communication link to a service center. There, the commissioning logs of all lift systems commissioned by a manufacturer can be archived and made available for later inspection.

In a further advantageous embodiment of the invention, a decrease test mode is selected as a function of a startup status. An acceptance test can only be carried out when the lift has been commissioned. On the basis of configuration data of the elevator installation, all necessary acceptance check steps are determined in the elevator control and stored in a memory of the elevator installation. By means of the acceptance inspection steps An acceptance test program is created, which is started by an acceptance tester and processes the acceptance test steps in a predetermined sequence. In this case, acceptance test steps are displayed by the display and control unit and required inputs of parameters of the elevator installation are entered via the display and control unit. By selecting the acceptance test mode, it is possible to determine the required steps for the acceptance test, which differ from the steps for commissioning. Here, too, the configuration data are based, so that the acceptance test program is specifically tailored to the specific elevator installation.

In an advantageous embodiment of the invention, an acceptance protocol is created, stored and / or transmitted to a service center after the execution of the acceptance test program. This allows details of the acceptance test to be understood later. In addition, a comparison of parameters of the stored commissioning protocol and the acceptance protocol can advantageously be carried out. This serves to further uncover irregularities or to confirm successful commissioning. By storing the logs, the electronic protocols of the commissioning and / or the acceptance test can be called up during maintenance work on the elevator installation or during modernization with the aid of the display and control unit and possibly updated according to the current state of the elevator installation.

In an advantageous embodiment of the invention, the acceptance protocol can be signed electronically by the acceptance tester or the commissioning protocol by the commissioning person. Since the person checking must identify himself prior to the start of the check, this identification can be used to make a personal signature of the generated minutes or certificates, which can later also be used to identify the person responsible for commissioning or acceptance testing.

Since corresponding certificates have to be generated for the acceptance test, in an advantageous embodiment of the invention, after the successful acceptance test has been completed, a acceptance certificate can be issued so that the acceptance tester does not have to perform any additional paperwork. A certificate can only be issued if the acceptance test program has been completely and successfully completed.

In an advantageous embodiment, the display and control unit can be used as a controller for test runs of components. The steps of the verification programs may require extensive testing of individual components of the elevator installation. The test runs can be controlled by inputs of the display and control unit, with test results are recorded and compared by the display and control unit.

The elevator installation according to the invention has a car, an elevator drive and an elevator control, which comprises a memory in which data for carrying out a startup and / or an acceptance test can be stored can be stored. The elevator controller is switchable to a commissioning mode or a checkout mode or a normal mode, and coupled to a display and operation unit for exchanging data. The display and control unit is provided for displaying a system state of the elevator system, error messages and / or steps for commissioning and / or acceptance test and allows input of data for controlling the commissioning and / or the acceptance test of the elevator system.

In such an elevator system, the essential information required to execute the commissioning and / or the acceptance test of a particular elevator installation is integrated and stored in the control system of the elevator installation. On the basis of this information, all the steps to be carried out during commissioning or acceptance testing are determined and stored in a program-controlled manner both for commissioning and for the acceptance test. The steps may come with a verification program in order Commissioning and / or acceptance test are processed by an authorized person menu-driven. In this case, set values can be displayed by the checking program, measured data can be recorded and, if necessary, compared with the setpoints. With the program system, the elevator control itself can be configured. All measures taken during commissioning and / or acceptance testing can be recorded, checked for completeness and correctness and stored in one or more files.

In an advantageous embodiment of the invention, the display and control unit is integrated in the elevator system. As a result, the resources of the elevator system can be used without having to connect additional devices to the elevator system.

In an alternative embodiment of the invention, the display and control unit is designed to be mobile and connectable to the elevator installation. In this case, the resources of the elevator system are not burdened by additional tasks. The display and control unit can be adapted to unreasonably increasing requirements without the elevator system having to be changed. As a display and control unit, for example, a notebook can be used. The display and control unit can be connected via wired or wireless or infrared-based communication links with the elevator system and communicate with the elevator system. The type of connection can thus be adapted to the requirements. It is advantageous if the display and control unit has a memory. In this way, the amount of data that needs to be exchanged between the elevator installation and the display and control unit can be reduced.

According to the invention, the memory in the elevator installation and / or the memory of the display and control unit contain programs and / or data which serve for the interactive control of the sequence of the startup and / or the acceptance test. This will have the advantage that the expiration of the reviews can be automatically generated without forgetting necessary steps.

In an advantageous embodiment of the invention, the elevator installation comprises a communication unit, via which a communication connection can be set up with a service center. Thus, the elevator installation is able to receive or send data from a service center.

In an alternative embodiment of the invention, the display and control unit comprises a communication unit, via which a communication connection to the service center directly between the display and control unit and the service center or indirectly via a communication link between the elevator system and the service center is buildable. Via the communication link to the service center, updates of the programs and / or data for interactive control of the commissioning procedure and / or the acceptance test or commissioning protocols and / or acceptance test protocols can be transmitted.

a flow diagram of the inventive method for performing a review of the elevator system.

In Fig. 1, the construction of an elevator system is shown. The elevator installation is provided with an elevator control 11, which has a processor 111. To the elevator controller 11, a memory 12 and a communication unit 14 are connected. The elevator control 11 is provided with an indicating and operating unit 13 connected. The display and control unit 13 has a display unit 131, an operating unit 132 and a memory 133. Furthermore, a processor 134 and a communication unit 135 are arranged in the display and operating unit 13.

In the memory 12 configuration data of the elevator system are stored. Depending on a selected operating mode, steps necessary for checking the elevator installation are determined by the processor 111 of the elevator control 11. By means of these steps, the processor 111 prepares a checking program which guides a checking person in a menu-driven manner through all steps of the checking. For this purpose, the steps are displayed on the display unit 131 and corresponding required inputs are input to the operating unit 132. Depending on the design, the checking program in the processor 111 of the elevator control 11 can be processed, wherein all the necessary data for display to the display unit 131 and also all input to the operating unit are transmitted to the processor 111 of the elevator control 11. Alternatively, the checking program can also be executed by the processor 134 of the display and operating unit 13, the configuration data being stored in the memory 133 of the display and operating unit 13. Via the communication unit 135 of the display and operating unit 13, a communication connection can be established to a service center, not shown, via which data can then be exchanged. Alternatively, the communication unit 14 of the elevator installation can be used to establish a communication connection with a service center. By default, the elevator installation has a communication unit 14 in order, for example, to place emergency calls in the event of faults to a fault control center.

FIG. 2 shows an elevator control ECU to which various components of an elevator installation are connected. The elevator controller ECU is connected to a frequency converter FC and a motor M. In addition, a door drive control ADDU is connected. Use control panels to set LOP to one Floors are transmitted control commands to the elevator control ECU. In addition, a cab COP is arranged in a cabin, which also serves to display information and to control the elevator and is connected to the elevator control ECU. In order to detect the position of the car floor dispenser LIN are arranged in the elevator shaft. To the elevator control ECU, a load measuring device LMG is further connected, which is provided for safety reasons and is used to position the car at the exit positions in the floors. A speed limiter GBPD is connected to the elevator control ECU and controls the speed of the car when moving in a hoistway. To determine the cabin movement, an incremental encoder IGV is also connected to the elevator control ECU. In this embodiment, an evacuation unit SEM is connected to the elevator controller ECU, which component is optional and is not installed on each elevator.

3 shows a flowchart for a method for checking the elevator installation. The diamonds in this flowchart indicate questions that can be answered with "yes" or "no". The arrows marked "+" indicate the respective next step in the case of the answer "yes" and the arrows marked with "-" indicate the next step in the case of the answer "no". In step 30, the process is started. Then the authorization of the person is queried in step 31. If there is no authorization, the procedure is ended (step 49). If an authorization exists, the configuration data of the elevator installation, depending on the embodiment, is called from a memory, queried by means of a program or supplied externally by means of a data carrier or via a communication connection (step 32). In step 33, the entered operating mode is queried. If commissioning is to be performed, the method continues with step 34. If an acceptance test is to be carried out, it is first checked in step 36 whether the elevator installation has already been put into operation. Otherwise, the process is terminated (step 49). In this flow chart is only the input of two different operating modes possible. If the commissioning mode has been selected, a start-up procedure program is created in step 34, which includes all steps that are required for the commissioning of an elevator installation with the specific configuration data from step 32. In step 35, this start-up procedure program is started. If the acceptance test mode has been selected, an acceptance test program is created in step 37 that includes all the steps required for an acceptance test of an elevator installation with the specific configuration data from step 32. In step 38, this acceptance test program is started. Regardless of which of the two possible verification programs has been started, the required steps are displayed on the display and control unit 13 in step 39. It is checked in step 40 whether an input of a parameter is required. If necessary, this input is entered via the operating unit 132 in step 41. The process remains in this loop until the step for commissioning or for the acceptance of the corresponding component has been completed (step 42). Next, in step 43, it is checked if the last step of the verification program has been completed. If the last step of the started check program has not yet been executed, the next step of the check program is executed (step 44). When the last step of the started validation program has been reached, the corresponding log is created based on the verification program (step 45). Assuming that the verification program has been processed successfully, the corresponding status of the check is set. In the case of commissioning, this is the commissioning status, in the case of the acceptance test an acceptance inspection status. After the corresponding status has been set, the corresponding protocol is signed in step 47. Thereafter, in step 48, the corresponding protocol or, if applicable, a certificate for the acceptance test is output, stored and optionally transmitted to a data carrier or via a communication connection.

In the following, individual components of the elevator installation are described by way of example, with the steps required for commissioning or acceptance testing being shown.

During commissioning, the mechanical requirements are first checked. This includes a check that all mechanical parts have been completely assembled. In particular, the catcher, the landing gear brake, the cabin door and the shaft doors are checked. This is followed by a review of the electrical components. This includes checking that appropriate cable connections have been mounted, for example, between the elevator control ECU and the door drive control ADDU, but these are not yet connected. It is checked that the manhole wiring has been completely terminated and connected to the door locks and floor panels LOP. The transmission wiring and the connections to the motor are checked. Furthermore, the cabin position in the shaft is checked, with the car should be positioned on the last floor. In a next step, the electrical connections of the individual components are made in a predetermined order. This requires a precise knowledge of the type of connections and the connection positions. After all electrical components have been connected and connected to the appropriate controls, the configuration of the elevator control is checked. In this case, switch positions must be checked or set, whereby here too the correct order must be adhered to and correct positions of the switches must be set. For example, in the presence of an evacuation unit multiple connections and switch positions must be made to the elevator control differently than when the elevator system has no evacuation unit.

After all connections and switches have been connected or positioned on the elevator control, the switches and connections must be set on a control unit on the cabin. When all cable connections have been made and all switches have their predetermined position, the elevator system is activated. For this purpose, a mains power cable must be plugged in and thermal magnets and differentials switched on. After activation, for example, the phase angles of the motors are checked. If these are not compliant, a series of steps must be taken until the phase is correct. Furthermore, a plurality of control LEDs are checked on different components at different positions on the elevator or in the elevator shaft.

Assuming that all steps have been processed successfully so far, the individual functions of the components are checked below. If all components are working properly, a first elevator inspection run will be carried out giving various control commands, the effect of which must be checked. Then the elevator is first moved at high speed. Again, the order of control commands must be followed. During these tests (synchronization drive, learn run), the elevator is synchronized, that is, it is set that the elevator stops at the correct positions in the floors. After these tests, the stick panels will be parameterized. For this purpose, the corresponding numbers must be displayed on displays of the floor control panels, depending on the respective floor. This must be programmed for each floor. Furthermore, the cabin load cell is calibrated. The cabin load cell is set to predetermined parameters. The commissioning engineer must check whether these parameters are within the specified tolerance range. For this purpose, the cabin must be loaded and moved with defined loads, with different distance measures taken and entered. It is also necessary to set how long the doors remain open, when a cabin fan is turned on, etc. Furthermore, the communication unit 14 of the elevator system is configured. For this purpose, the communication unit 14 must be connected to a telephone connection and corresponding telephone numbers of the fault center be programmed. In addition, the intercom system in the cabin is set and tested.

The acceptance test also includes checking switch positions, measuring distances, checking or affixing labels, testing luminaires at different locations, checking safety symbols, testing the communication unit, checking and securing access to the manhole, and specifying landing door locks. It is particularly important to check whether all safety-relevant components and systems, such as the safety gear for a car and the safety contacts and safety circuits for monitoring the elevator system, meet the required legal standards or regulations. Furthermore, a number of intervals are recorded and compared with setpoints. Cabin type, guide rails and rail fasteners must be specified. In addition, the weight of the empty cabin is recorded and checked. The functions of the car are checked, in particular an overload device that prevents a normal start-up with excessive weight. The emergency exit hatch in the cabin must be checked. Clearances of the car to the shaft, the door distance and the distance of the car to the door threshold are recorded and compared with setpoints. An important point in the acceptance test is the inspection of the ropes, where rope parameters such as number and diameter are recorded and checked. Furthermore, the anchoring of the ropes to the cabin and to the drive is checked. It is also necessary to check markings on a speed limiter rope. The next step in the acceptance test is to test and test the engines and their components. This includes, for example, temperature monitoring of the drive motor, the door drive motors and the frequency converter. The running time of a motor runtime limiter must be checked. Next, the electrical wirings are checked. This includes a check of the grounding, the insulation resistance and the electrical wiring also with respect to an EMC measurement. The acceptance tester must check whether documents required for the operation, such as registration book and manual instruction book, are available. Finally, a number of forms must be completed.

The above list of activities relating to commissioning and acceptance testing makes it clear how complex such reviews are. The method according to the invention for carrying out checks makes it easier for the person checking to check, with the check according to the invention simultaneously bringing about an improvement in terms of completeness and safety.

Due to the configuration data, from which each point can be derived for commissioning and acceptance testing, the selected type of check menu-controlled via the display and control unit 13 can be performed. The commissioning engineer can set, compare or set all elevator control parameters in a manageable manner.

When using a mobile display and control unit 13, which is connected to the elevator system, a distributed system for generating the verification program can be used for the inventive method. Since acceptance tests and commissioning take place in steps that are essentially the same for different elevator systems, these steps of the checking programs can be stored in the display and operating unit. The plant-specific detail aspects, however, strongly depend on the configuration of a specific elevator installation. Thus, the part of the checking program which is independent of the concrete configuration of an elevator installation and the information about the progress of the check can be stored in the display and control unit 13 as a menu structure. The details are then inserted from the configuration data of the specific attachment into this menu structure so that the steps of the verification program are specified by this configuration data.

The program-controlled processing of both commissioning and acceptance testing makes the checks more comfortable and safer. Moreover, the time required for the checks is optimized. The examiner can concentrate entirely on the inspection of the lift system, without constantly having to look up technical documentation. In addition, the transport of a mobile display and control unit 13 in the review of an elevator system is more comfortable than many documents to carry with it, especially since the inspector has to move a lot in large elevator systems and must work in inaccessible places.
