As shown in FIG. 4B, a plurality (three in this embodiment) of service LEDs 1181 for self-diagnosis of the switch board 72 (see FIG. 2) are provided on the main body operation section 116.
, 1182, 1183, and the operation changeover switch 122 for changing over the operation mode of the air conditioner 10 to any one of "all stop", "operation", "test operation" and "DEMO".

Normally, the air conditioner 10 has the operation changeover switch 1
22 is used with the "drive" position. When the air conditioner 10 is installed, tested, or adjusted, the operation changeover switch 122 is set to "all stop", "test run", and "DEMO".
Position. Further, the self-diagnosis of the air conditioner 10 is performed by setting the operation changeover switch 122 to "all stop" and then to "test operation".

Next, the operation of this embodiment will be described with reference to the flow chart showing the control routine (see FIG. 5). As described above, this routine is started when the air conditioner 10 is stopped due to a trip or the like, and the serviceman switches the operation changeover switch 122 to "all stop" and then to "test operation".

Here, the air conditioner 10 is provided with various sensors as described above, and if any of these is abnormal, data for identifying the sensor in which the abnormality is occurring. Are stored in the RAM (not shown) of the microcomputer 56. In addition, the cause of the trip that occurred this time and the previous time is also stored in this RAM.

When this routine starts, step 1
In 02, the data for identifying the sensor in which an abnormality has occurred is read from the RAM, and in step 104, the RA
The cause of the trip that occurred this time or the previous time is read from M.

In the next step 106, the sensor in which an abnormality has occurred is displayed. This process (step 10
Details of 6) will be described later.

When the display of the sensor in which the abnormality has occurred is finished, in step 108, for a predetermined time, for example,
In the present embodiment, it is determined whether 1 [S] has elapsed, and 1 [S] is determined.
When the time has passed, in step 110, the buzzer 77 is sounded twice in order to clarify the switching of the display of the cause of trip from the display of the sensor in which the abnormality has occurred. As a result, it is possible to notify the serviceman that all the sensors in which an abnormality has occurred are displayed, and the serviceman can also know that the trip cause will be displayed next.

In step 112, it is determined whether or not a predetermined time, for example, 1 [S] has elapsed in this embodiment. If 1 [S] has elapsed, the cause of trip is displayed in step 114. The details of this process (step 114) will be described later.

When the display of the cause of trip is completed,
In step 116, a predetermined time, for example, 1 in this embodiment.
It is determined whether or not [S] has elapsed. When 1 [S] has elapsed, in step 118, the buzzer 77 is sounded three times to notify that the display of the cause of trip has ended. As a result, it is possible to notify the serviceman that the display of all the sensors in which an abnormality has already occurred and the cause of trip has been completed.

In this way, since it is possible to inform that the display of all of the sensor in which the abnormality has occurred and the cause of the trip has ended, the service person cannot know the sensor in which the abnormality has occurred and the cause of the trip. In this case, the operation changeover switch 122 is switched again and the above-described processing is executed to confirm the sensor in which the abnormality has occurred and the cause of the trip. In addition, considering that the sensor in which an abnormality has occurred and the cause of the trip may be unknown, the control routine shown in FIG.
The process may be repeated a predetermined number of times (for example, three times) to end.

Next, the details of step 106 will be described with reference to the flowchart (see FIG. 6) showing the subroutine of the process.

As described above, since the data for identifying the sensor in which the abnormality has occurred is read in step 102, the variable s for identifying the sensor corresponding to the read data is set to 0 in step 122. Initialize, in step 124, increment the variable s by 1,
At 26, the blinking pattern of the service LED corresponding to the sensor identified by the variable s is read from the sensor correspondence table (see FIG. 8) stored in the RAM. In FIG. 8, “0” indicates that the corresponding service LED is not blinked, and “1” indicates the corresponding service LE.
It indicates that D is made to blink. For example, if there is no abnormality in all sensors, all service LEDs
“0” is stored in the column. If the room temperature sensor is abnormal, "1" is stored in the service LED 1181 column and "0" is stored in the other service LEDs 1182 and 1183.

In the next step 128, the service LEDs 1181 and 1182 are based on the read blinking pattern.
, 1183 blinks. For example, service LED
“0,0,0” for 1181, 1182 and 1183
Is read, all service LEDs 118
Do not blink 1, 1182 and 1183. On the other hand, an abnormality occurred in the room temperature sensor, and service LEDs 1181 and 11
When "1, 0, 0" is read for 82 and 1183, only the LED 1181 is blinked every 0.5 [S] five times. That is, for example, as shown in FIG. 10A, the process of turning on the LED 1181 by 0.5 [S] for 1 [S] is performed 5 times during 5 [S].

At the next step 130, it is judged whether or not the variable s is equal to or larger than the number S0 of data read out at step 102 (the number of sensors having an abnormality), and the variable s is not equal to or larger than S0. In some cases, there is a sensor that has an abnormality that is not yet displayed. In this case, in step 134, for a predetermined time, for example, 1 [S] in this embodiment.
When 1 [S] has elapsed, it is determined whether or not the time has elapsed, and in step 136, the blinking display of the service LED based on the pattern performed last time and the blinking display of the service LED based on the next pattern are performed. In order to make a distinction, the buzzer 77 is sounded, the process returns to step 124, and the above processing (steps 124 to 130) is repeated. Since the buzzer 77 sounds in this manner, the serviceman is recognized by distinguishing the blinking display of the service LED based on the pattern performed last time and the blinking display of the service LED based on the pattern performed next time.

On the other hand, if the determination in step 130 is affirmative, the process returns to step 108.

Next, the details of step 114 will be described with reference to the flowchart (see FIG. 7) showing the subroutine of the processing.

As described above, since the trip cause is read in step 104, the variable u for identifying the read trip cause is initialized to 0 in step 142, and the variable u is incremented by 1 in step 144. Then
In step 146, the lighting blinking pattern of the trip cause (the last trip cause) identified by the variable u is set to the above R.
Trip cause correspondence table stored in AM (FIG. 9)
Read). In FIG. 9, “0” indicates that the corresponding service LED does not blink, “1” indicates that the corresponding service LED blinks, and “1”
"0" indicates that the corresponding service LED is turned on. For example, when there is no trip, "0" is stored in the columns corresponding to all the service LEDs. Also, if the serial communication failure is the cause of the trip,
"10" is stored in the field of the service LED 1181, and "0" is stored in the fields of the other service LEDs 1182 and 1183. Further, if the switching failure of the four-way valve is the cause of the trip, "10" is stored in the service LED 1181 column and "1" is stored in the service LED 1182, 1183 columns.

At the next step 148, the service LEDs 1181 and 11 are set based on the read lighting blink pattern.
8 2 and 1183 are lit and blinked. For example, for the service LEDs 1181, 1182, 1183, "0,
If "0, 0" is read, all service LEs are
Do not blink D1181, 1182 and 1183. On the other hand, service LEDs 1181, 1 due to poor serial communication, etc.
When “10, 0, 0” is read for 182 and 1183, only the LED 1181 is read, for example, as shown in FIG.
As shown in (b), the light is continuously turned on for 5 [S].
In addition, the service LED 11
When "10, 1, 1" is read for 81, 1182, 1183, only the LED 1181 is continuously turned on for 5 [S] as described above, and the service LED is turned on.
1182 and 1183 as shown in FIG.
Flashes every 0.5 [S] five times.

At the next step 150, it is determined whether the variable u is greater than or equal to the number u0 of data read out at step 104 (2 in the present embodiment because the last and previous trip causes are stored). If the variable u is not equal to or greater than u0, the previous trip cause is not displayed. In this case, therefore, in step 152, a predetermined time, for example, 1 [S] has elapsed in this embodiment. It is judged whether or not 1
If [S] has elapsed, in step 154, the service LED corresponding to the cause of the last trip is displayed with a blinking light and 1
In order to clearly distinguish the lighting and blinking display of the previous trip cause, the buzzer 77 is sounded, the process returns to step 144, and the above processing (step 144 to step 150) is repeated. Since the buzzer 77 is sounded in this manner, the serviceman is recognized by clearly distinguishing the display of the last trip cause and the display of the previous trip cause.

On the other hand, if the determination in step 150 is affirmative, the process returns to step 116.

As described above, in the present embodiment, the buzzer sounds when the service LED blinks or the lighting display is switched when the sensor in which an abnormality has occurred and the cause of the trip are displayed. If there is more than one sensor with an error, the display of that sensor switches, that is, the display of the cause of the trip changes from the display of the sensor with the error, and the previous trip cause is one The switching to the cause of the trip is clearly distinguished and recognized by the service person, and the display of the sensor in which the abnormality has occurred and the display of the cause of the trip are not overlooked.

Further, in the above-described embodiment, the service LED is blinked when the sensor in which the abnormality is occurring is displayed, and at least one of the service LEDs is turned on when the cause of the trip is displayed. Therefore, the sensor in which the abnormality has occurred and the cause of the trip are clearly distinguished and recognized.

[0056]

As described above, according to the present invention, the light emitting means is turned on or blinked or turned on and off according to the pattern corresponding to one device having an abnormality, and another device having an abnormality is generated. According to the pattern according to the above, the light emitting means is turned on or blinks or a sound is issued before turning on and blinking, so that the switching of the display of one abnormal state to another abnormal state becomes clear, and the service person Has an effect of being able to recognize all the places to be repaired such as the cause of trip.
