11.1. Alarm Recovery
Probe alarms P1, P2, P3, and P4 start some seconds after the fault in the related probe; they automatically stop some seconds
after the probe restarts normal operation. Check the connections before replacing the probe.
Temperature alarms HA, LA, HA2, and LA2 automatically stop as soon as the temperature returns to normal values.
Alarms EA and CA (with i1F = bAL) recover as soon as the digital input is disabled. Alarm CA (with i1F = PAL) recovers only by
switching OFF and ON the device.
TEMPERATURE ALARM
HA Temperature alarm from parameter ALU on probe rAL. Outputs unchanged.
LA Temperature alarm from parameter ALL on probe rAL. Outputs unchanged.
HA2 Second high temperature alarm. Outputs depends on setting.
LA1 Second low temperature alarm. Outputs depends on setting.
DIGITAL INPUT ALARM
dA
Door open alarm from input i1F, i2F or
i3F = after delay d1d, d2d or d3d.
Cooling relay and fan follow the odc parameter.
Cooling restart as specified on rrd parameter.
EA
Generic alarm from digital input i1F, i2F,
i3F = EAL.
CA
Severe alarm of regulation lock from digital input i1F,
i2F, i3F = bAL.
Regulation output OFF.
PAL Pressure switch lock i1F, i2F or i3F = PAL. All the outputs are OFF.
CLOCK ALARM
rtC Clock settings lost.
Defrost will be performed with IdF till restoring the
settings of RTC.
rtF Clock damaged. Defrost will be performed with IdF.
OTHERS
EE EEPROM serious problem. Output OFF.
Err Error with upload/download parameters. Repeat the operation.
End Parameters have been correctly transferred.
dEF Defrost is in progress.
cLn Cleaning function is active.
