by-passed for AL04 (to control the unit restart) if
during this time the alarm recovers.
AL07
Minimum time with inactive water flow input
(after alarm event).
After a water flow alarm event, with stop compressor,
the regulation restarts only if after this time the digital
input is not more active. It prevents from a possible
series of short alarms due to the presence of air into
the water pipe.
AL08
Thermal protection alarm delay time for
compressors.
After switching on the compressor the thermal
protection alarm is not detected for the time set in this
parameter.
AL09
Number of maximum thermal protection alarm
events.
If during one hour the number of thermal alarms
reaches the value set in this parameter, the alarm
reset turns to manual procedure.
AL10
Thermal protection alarm reset after AL09
events/hour.
After the number of maximum alarms/hour for
compressors 1–2,
AL10
parameter automatically
change to
1
. To reset this alarm is necessary to enter
the programming and change it again to
0
.
This operation executed only by personnel in charge
for the maintenance prevent compressor damaging
caused by frequently alarm resets.
AL11
Condensing high temperature/pressure alarm
setpoint. When the condenser probe value increases
over this value the instrument detects this high alarm.
AL12
Condensing temperature/pressure differential to
reset the high alarm.
AL13
Condensing low temperature/pressure alarm
delay time for analogue input. After a compressor
starting, the low pressure alarm coming from digital
input is delayed for the time set in this parameter.
AL14
Condensing low temperature/pressure alarm
setpoint. When the condenser probe value decreases
under this value the instrument detects this low alarm.
AL15
Condensing temperature/pressure differential to
reset the low alarm.
AL16
Maximum number of low pressure alarms in
one hour before turning to manual reset procedure.
AL17
Open collector and relay alarm output control
when the unit is in Off or in Stand-by status.
0 = Outputs not enabled for alarm events;
1 = Outputs enabled for alarm events.
AL18
Alarm output polarity.
0 = Active for closed contact (open for normal condit.);
1 = Active for open contact (closed for normal condit.)
AL19
Alarm printout language through IR device.

Logging Parameters
The data recording is enabled only for IR device
mounted on board and the parameter LG08<>0. The
parameters from LG01 to LG07 can enable which are
the recordable data .
LG01
Functioning status (Chiller, Heat Pump,
Standby)
0 = Not logged, 1 = Yes
LG02
Probe temperature Pb1.
0 = Not logged, 1 = Yes
LG03
Probe temperature Pb2.
0 = Not logged, 1 = Yes
LG04
Probe temperature/pressure Pb2.
0 = Not logged, 1 = Yes
LG05
Probe temperature/pressure Pb4.
0 = Not logged, 1 = Yes.
LG06
1
st
Compressor status.
0 = Not logged, 1 = Yes 1
st
Compressor.
LG07
2
nd
Compressor or valve status.
0 = Not logged, 1 = Yes 2
nd
Compressor/valve.
LG08
Interval recording time (10 seconds step).
Each time the configuration of LG01-LG07 is
changed, the memory automatically deletes the old
data and prepares itself for new logging cycle.
