7. ALARM SIGNALLING
Mess. Cause Outputs
“P1” Room probe failure
Compressor output
according to Cy e Cn
“HA” Maximum temperature alarm Outputs unchanged
“LA” Minimum temperature alarm Outputs unchanged
“EA” External alarm Outputs unchanged
“CA” Serious external alarm All outputs OFF
“dA” Door Open
ALARM RECOVERY
Probe alarm “P1” starts some seconds after the fault in the related
probe; it automatically stops some seconds after the probe restarts
normal operation. Check connections before replacing the probe.
Temperature alarms “HA” and “LA” automatically stop as soon as
the temperature returns to normal values.
Alarms “EA” and “CA” (with iF=bA) recover as soon as the digital
input is disabled.
