Accessing parameters
Press
z
and at the same time
é
: the keypad now operates in
Parameters MENU mode and the parameters can be scrolled with
z
and
é
.
List of parameters
A1
Sets the unit of measure for dew point in °C or °F.
A2/A3
Total hours of dryer operation = A2
(display only).
A4/A5
Like A2/A3 but for hours of refrigeration compressor opera-
tion.
A6
Sets Hd Warning intervention temperature (see par. 5.4 in
List of alarm/warnings).
A7
Inhibits remote OFF command.
b1
Sets the dryer address for serial communications.
b2
Sets the serial communication speed.
b3
Not available
b5
Refrigerant evaporation temperature.
b7
Not available
b8
Compressor discharge (delivery) temperature.
b9
Not available
C5
Dryer model:
Mon = models PST120-350
MuL = models PST460-1800
Note
: if the C5 is set to = MuL in a monocooler dryer then
the warning ASE will occur. ASE is a warning for the multi-
cooler models..
C7
Sets compressor operation mode:
- CYC = CYCLING (energy saving enabled)..
- Con = CONTINUOUS (energy saving disabled)..
C36
Operating logic of the alarm/machine status relay.
0 = relay energised when dryer is running, de-energised if
in warning/alarm status.
1 = relay de-energised when dryer is running, energised if
in warning/alarm status.ù
2 = relay de-energised when dryer is not running,
energised when running.
C37
% energy saving.
d1
Sets the seconds of condensate drain opening (if set in
TIMED mode).
d2
Like d1, but for seconds closed.
d3
ISets condensate drain operation mode:
- CAP = INTEGRATED
- tIM = TIMED
- Con = EXTERNAL (24VAC)
Changing parameters
After displaying the parameter, press
x
, change with
z
and
é
,
, then press
x
to confi rm.
Press
y
to return to STANDARD mode.
5.4 Alarms and Warnings
Alarms
cause the dryer to switch off.
Warnings
only cause a signal.
In the case of Alarm or Dew Point Sensor Warning (dSE),
[
displays
the alarm code. In the case of a Warning,
[
alternatively displays
the fault code and the dew point and WARNING LED comes on.
If an alarm occurs:
a) Identify and eliminate the cause;
b) press
z
to reset the alarm;
c) press
x
to restart the dryer.
If a warning without automatic reset occurs:
a) identify and eliminate the cause
b) press
z
to reset the warning.

Lt
Low Evaporation Temperature Alarm
Ht
High Compressor Discharge Temperature Alarm = T> 120°C.
rSE
Refrigerant Temperature Sensor Warning
Switches to CONTINUOUS mode.
drE
Condensate Drain Warning
Condensate drainage switches to TIMED mode.
dSE
Dew Point Sensor Warning
The measured temperature must return within its normal range.
Hd
High Dew Point Warning
Automatic reset when the dew point = A6 - 4°F (2°C).
HSE
Discharge temperature sensor Warning
Sr
Scheduled Maintenance Warning
See par. 5.2 and 6.3
