11.Sensor failure
(1)Temp. sensor Open circuit:
Short circuit:
E01 and 50 are displayed alternately, the buzzer beeps intermittently and remote alarm contact outputs.
The compressor would be allowed to turn on. Press BUZZER key to stop the buzzer beeping.
E02 and
The compressor would be allowed to turn on. Press BUZZER key to stop the buzzer beeping.
(2) | Comp. sensor |
|
| Open circuited: | E05 and PV are displayed alternately, the buzzer beeps intermittently |
|
| and remote alarm contact outputs. |
|
| Press BUZZER key to stop the buzzer beeping. |
| Short circuited: | E06 and PV are displayed alternately, the buzzer beeps intermittently |
|
| and remote alarm contact outputs. |
|
| Press BUZZER key to stop the buzzer beeping. |
(3) | Compressor | E10 is displayed and compressor turns off when temperature in Comp. |
| abnormal temp. | sensor is higher than 100 . When temperature in Comp. sensor is lower |
|
| than 65 , compressor turns on. |
(4) | Error code priority |
|
| No.1: | Temp. sensor failure (E01 or E02) |
| No.2: | Comp. sensor failure (E05 or E06) |
| No.3: | Compressor abnormal temperature (E10) |
(5) Temperature to judge sensor failure
PT sensor: 49.9 or higher (E01 displayed) … Judge as ‘Open circuited’
130or higher (E06 displayed) … Judge as ‘Short circuited’
12.When the power is supplied (without battery)
Compressor: In PV is higher than SV, compressor turns on with 2minutes (initial value) of delay after the power was supplied.
With temperature in Comp. sensor is lower than 20 , Fan motor would not activate even if the power is supplied. Fan motor starts rotating once the temperature in Comp. sensor is reached equal or higher than 80 .
