Alarms and Sign a lling
 TEMPERATURE DISPLAY IS BLINKING :
Door opened for more than d8 value.
 BLINKING INDICATOR LIGHT :
The output or the function is delayed or waiting for an external command (digital input).
- E0 BLINKING : Ambient probe fault
Probe used with the regulator is incompatible, short circuit or cable cut, probe not working properly: disconnect the probe
from the regulator and check the probe resistance (NTC: 0°C = 27 KOhms).
- E1 BLI NKING : cooler probe fault
see E0
- IA BLINKING : alarm given by the digital input . Compressor fault in most of c a ses
Check the status of the digital inputs ID1 and ID2, and A4, A5 parameters.
- dA BLINKING : delayed alarm given by the digital input
Check the status of the digital inputs ID1 and ID2, and A4, A5, A7 parameters.
- L0 BLINKING : low ambient temperature
Check the following parameters: AL, Ad and A0. The alarm disappears when the temperature come back to a value inside the
selected limits.
- HI BLINKING: high ambient temperature
Check the following parameters: AH, Ad and A0. The alarm disappears when the temperature come back to a value inside the
selected limits.
- EA , EB , EE BLINKING: fault in the data log.
You need to initialise the regulator to the default values.
- Unplug the regulator by disconnecting the main power.
- Re-connect the regulator with the key pressed.
- On the display “-C-“ appears
- After a few seconds, the regulator sets up all the default values in the parameters.
- If the error EE is always displayed, press the key until the error disappears.
- Attention: If you use this command, all the values you have already entered will be lost.
- Set up your values in the regulator.
- Ed BLINKING: timeout for the defrost cycle. The maximum time for a defrost cycle has been reached.
- Check the defrost efficiency.
- Check the following parameters: dt, dP,d4 and r3.
- dF BLINKING: a defrost cycle is operating.
This is not an alarm. This message appears only if a defrost cycle is activated and if the parameter d6=0.
