ALARMS
ALARMS WITH IMMEDIATE COMPRESSOR SHUT-OFF
Code Description Cause
01 EMERGENCY STOP Emergency stop button open (IN1)
02 MOTOR OVERLOAD Thermal motor open (IN2)
03 THERMAL FAN Thermal fan open (IN3)
04 NO PHASE One or more phase missed for over 300 m.s.
05 WRONG PHASE Phase inverted
07 DOOR OPEN IN7 open (set as come door micro-switch)
09
DRIVE FAULT
Input relay fault drive open/closed (alarm managed with input enabled only
(C21=1/2))
11 HIGH PRESSURE Working pressure over set WP2
12 T. PROBE FAILURE Air end temperature probe failure
13 HIGH TEMP. Air end temperature over set WT1
14 LOW TEMP. Air end temperature lower than set WT5
15 SEPARATOR FILTER
Delta P (internal pressure – working pressure) over shut off set AP1 once the
timer C19.1 is over and air end temperature is over 45°C (alarm managed
when the aux pressure transducer is enabled into differential operation
(C19=2))
18 POWER OFF In case of power off and compressor set as manual restart
20 TEMP. MOTORE PTC input open
21 INPUT POWER FAULT Safety pressure switch open (missing power to all digital inputs)
22 INPUT IN7 Parameter C12 = 3 (generic alarm)
25 SEPARATOR FILTER Separator filter differential pressure switch open (IN6)
ALARMS WITH COMPRESSOR SHUT-OFF AFTER 30 SECONDS UNLOAD RUNNING
Code Description Cause
26 PRESS. TRANSD. FAILURE Working pressure transducer failure
27 AUX. TRANSD. FAILURE Aux. Pressure transducer failure
28 LOW VOLTAGE
Power supply to the controller lower than 9,5Vac and reset accepted when the
power goes over 10,6Vac.
It is not visualized in case it has been disabled in menu 4 Compressor SETUP
29 SAFETY Timer CAF elapsed: this alarm is detected if the parameter Safety is set YES
30 HIGH TEMP. WARNING
Air end temperature over set WT2.
Reset once temperature is lower than WT2-5°C
32 CHECK COMPRESS. Timer C—h elapsed: reset the related maintenance timer
33 RS 485 FAILURE
In case compressor start/stop is operated via RS232 and the watchdog
function is enabled (see MODBUS protocol communication)
60 INVERTER FAILURE In case of inverter via RS485, shut off alarm detected (managed by inverter
connected via RS485 only (DR0>0))
62 COMMUNICATION INVERTER No communication to inverter in case of connection via RS485 (managed by
inverter vua RS485 only (DR0>0))
NOTE :
Every time a shut-off alarm is detected, both relay set as alarm led DL1 are activated; the alarm message is stored into the
alarm list; once the cause of the alarm has been erased, push the button
R to reset the message and start the compressor.
