1592020062 XR60CX GB ES m&M r1.1 05.03.2007.doc XR60C 4/5
Message Cause Outputs
"LA2" Condenser low temperature It depends on the “bLL” parameter
“dA” Door open Compressor and fans restarts
“EA” External alarm Output unchanged.
“CA” Serious external alarm (i1F=bAL) All outputs OFF.
“CA” Pressure switch alarm (i1F=PAL) All outputs OFF
14.1 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 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 instrument.
