ALARM SIGNALS
ALARM RECOVERY
Probe alarm “
P1
” starts some seconds after
the fault in the related probe; it automati-
cally stops some seconds after the probe
restarts normal operation. Check connec-
tions before replacing the probe.
Temperature alarms “
HA
” and “
LA
” auto-
matically stop as soon as the thermostat
temperature returns to normal values and
when defrost starts.
Alarms “
EA
” and “
CA
” (with i1F=bAL) re-
cover as soon as the digital input is
disabled.
Alarm “
CA
” (with i1F=PAL) recovers only by
switching off and on the instrument.
