DE3010051A1 - Cabinet-mounted fault indicating assembly - uses rack mounted modules containing number of visual and acoustic fault indicators - Google Patents

Abstract

A fault indication system uses a number of rack mounted modules containing a number of displays indicating an alarm condition. The cabinet has a number of horizontal rails that provide guidance for the slide in modules. Typically, each module contains four alarm indicators coupled to input lines that are sampled by a motor driven switching stage. An acoustic device is used to emit a warning signal that may be manually switched off. Switches may be reset to return the system to a state of readiness.

Description

Fault reporting compact system

The invention relates to a compact fault reporting system for detection of malfunctions in the entire electrotechnical area, especially where they occur Errors at a specific location must be located quickly and comprehensively.

In the case of such alarm systems, it is easy to identify errors On the one hand, notify the specialist who remedied the fault should be where the error can be found and on the other hand the bed porter or machinist - should communicate that the system is no longer running or functioning continuously Recognition of the occurring errors within a machine or a large one Installed system must be ensured.

Fault reporting devices are known to meet these requirements to arrange the occurring faults sufficiently display and report. It is It is necessary, however, to use a large number of fault signaling devices and additional relays for incandescent lamps etc. to provide each grouped together in a cabinet and ver - need to be wired.

The invention is based on the task of assembling many To reduce fault signaling devices and other associated relays and their assembly work and to simplify the installation of alarm systems.

According to the invention, this object is achieved in that the fault reporting compact system from a general cabinet with a basic device and several additional devices each are made for themselves and each record a certain part of the disturbances is composed.

In order to have such a compact alarm system, each for a specific System is assembled, assemble in a simple manner by assistants can, according to a further embodiment of the invention, the general cabinet and the associated basic and additional devices with slide rails for insertion and with Provide plug connections to snap into the provided sockets.

The advantages achieved with the invention are in particular: that instead of a multitude of different relays and components they are only assembled and all that needs to be wired is a cabinet with drawers for the respective Size of the system the additional devices to be kept ready can be inserted.

The most favorable combination of alarm devices is required in each case If necessary, only push it in at the point of use with a few simple steps of the basic device or, if necessary, further suitable additional devices #, they can be checked there immediately by an assistant.

An embodiment of the invention is shown in the drawing and is described in more detail below. Fig. 1 shows the general cabinet with an already inserted basic device and an additional device that has just been inserted will.

Fig.3a The circuit diagram of the additional device with four built-in fault indicator lights.

The number of indicator lights is not binding, it can be determined by the manufacturer Any number of additional devices can be reduced or expanded as required Only the wire coming from the alarm contact has to be connected to the provided terminal in the connection area. When operating with the same outer conductor, for example L1, a wire is required for each fault indicator light.

An alarm contact must be built into the devices to be monitored from here, in the event of a fault, the voltage across the laid The wire is routed to the compact fault alarm system. The wire is connected to the designated In this case, terminal No. SD 1 is connected. This becomes the motor-driven rear derailleur d3 that the indicator lights All - 4 are continuously working in rhythm monitored switched off. An acoustic signal H1 gives an alarm message and the In this case, Al 1 flashes, and a collective light is also lit. SS in the basic unit as a reserve. The acoustic signal can be activated via a button who are switched off immediately until the fault is eliminated, After the fault has been eliminated or the Alarm contact KEd, the system automatically switches back on via d2 + C2 This also switches the switchgear on again at the same time. After the first fault has been reported, the system is still ready for operation, it can any further fault with the associated indicator light by flashing the addressed report light. So that the acoustic signal does not sound continuously in the event of subsequent malfunctions the horn remains switched off after pressing the button until all faults are fixed.
