Troubleshooting RAS devices

Self-Diagnosis by Remote Control (Check Code)

(1) If the lamp are indicated as shown B to G in Table 9-3-1, exchanger the self-diagnosis by the remote control.

(2) When the remote control is set to the service mode, the indoor controller diagnoses the operation condition and indicates the information of the self-diagnosis on the display of the remote control with the check codes. If a fault is detected, all lamps on the indoor unit will blink at 5Hz and it will beep for 10 seconds (Pi, Pi, Pi, …).

The timer lamp usually blinks (5Hz) during the self-diagnosis

1) How to use remote control in service mode

(1) Press (CHK) button with a tip of pencil to set the remote control to the service mode.



“00” is indicated on the display of the remote control



The timer lamp on the indoor unit blinks continuously. (5 times per 1 sec.)

(2) Press [TIMER ] button

If there is no fault with a code, the indoor unit will beep once (Pi) and the display of the remote control will change as follows:

00  01 02  . . . 1d  1E  22



Check the unit with all 35 check codes (00 to 22) as shown in table 1



Press [TIMER ] button to change the check code backwards

If there is a fault, the indoor unit will beep for 10 seconds (Pi, Pi, Pi,…)

Note the check code on the display of the remote control



2-digis alphanumeric will be indicated on the display



All lamps on the unit will blink. (5 times per 1 sec.)

(3) Press [CLR] button. After service finish for clear service code in memory.



“7F” is indicated on the display of the remote control

(4) Press [ ] button to release the service mode.



The display of the remote control return to as it was before

Alphanumeric characters are used for the check code: service mode was engaged. is 5. is A. is C. is 6. is B. is D.

* The illustration in only for Heat pump module.

For cooling only model, there is not the () symbol

. page 6  TOSHIBEL 2.1


2) Caution at servicing

(1) After servicing, push the START/STOP button to return to the normal mode.

(2)

After servicing by the check code, turn off breaker of the power supply, and turn on breaker of the power supply again so that memory in the microcomputer returns the initial status. However, the check codes are not deleted even if the power supply is turned off because they are stored in the fixed memory.

Testing methods

On the remote controller (Main remote control, central remote controller) and the interface board of the outdoor unit (I / F) is an LCD display

(remote control) or a 7-segment display (interface board) to indicate the particular function.

There you have the opportunity to check the function. With the help of self-diagnosis problems or equipment failure can be easily found by using the following table.

List of faulty codes

The following list includes all error codes. With this list you can find the content which has to be tested of each unit

 check with the remote control unit for the area: See "Main remote controller display" in the list.



Examination of outdoor unit: See "7-segment display, outdoor unit" in the list.

 check with the central AI-NET remote controller: See "AI-NET central remote control" in the list.



Test with an infrared remote control for indoor unit: See "Sensor block display of receiving unit" in the list.

The standard ducted unit air conditioner utilizes a direct current (DC) indoor fan motor that features current limiting protection. In the event power is not isolated prior to service, the protective control circuit will activate and stop the unit operating. The check code P12 will be displayed on the remote controller-once service work has been completed, this code can be cleared by switching off the electrical isolation device of the indoor unit and pressing the operation stop button on the remote controller to reset the system.

Fault Codes – 3-Pipe Super Multi

Do not turn off the power supply before reading the fault codes, doing so will clear the diagnostic memory. Caution must be taken when removing the access covers, as high voltages are present.

Fault diagnosis is available at three locations within the Air Conditioning system:

1. Remote Controller – Press the check button

2. Multi Controller – rotate the display switch to position 1

3. Outdoor Unit – see following chart:
