is symptomatic of poor drainage.
Th is check of the timed drain opening (parameter d1).
Settings depends upon the operating conditions of the dryer and
varies the amount of condensate to be removed.
For standard dryer operating conditions, see the following table of
recommended settings:
Model
PST120-350
Parameter d1: time open in seconds for every 2 minutes of opera-
tion.
c) EXTERNAL - if there is an external drain.
To change operation mode, use the parameter d3 (see par. 5.3 in List of
parameters).
Y
Only set the EXTERNAL mode in absence of the solenoid valve.
Otherwise the relative coil could become damaged.

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 mul-
ticooler 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 TI-

MED mode).
d2 Like d1, but for seconds closed.
d3 ISets condensate drain operation mode:
- CAP = INTEGRATED
- tIM = TIMED
- Con = EXTERNAL (24VAC)

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,
displays the fault code and the dew point and WARNING LED comes
on.
If an alarm occurs:
a) Identify and eliminate the cause;
z
b) press to reset the alarm;
x
c) press to restart the dryer.
If a warning without automatic reset occurs:
a) identify and eliminate the cause
z
b) press to reset the warning.
