DISPLAY
Via a digital thermometer with an alphanumeric display, the DMC14 electronics indicate the dew point which is meas-
ured by the sensor in the evaporator.
The LED indicates possible alarm situations, for example:
if the dew point is too high;
if the dew point is too low;
if the sensor is defective.
In the event that the sensor is defective, the message "PF" (Probe Failure) is also indicated and the alarm is immedi-
ately activated. In the event of a "Dew point too low" alarm message (fixed ASL parameter, corresponding to -2°C), the
alarm signal is delayed (ADL parameter) by a fixed period of time of 30 seconds. For the "Dew point too high" mes-
sage, the value (ASH parameter) is fixed by the user and the signal is activated with an ADH delay time which can
also be set by the user (the control unit was already preset during the acceptance test of the dryer in the factory: see
the following values). As soon as the dew point lies again in the adjusted operating temperature range, the alarm is
deactivated.
The DMC 14 control unit also allows remote signalling of alarm situations of the dryer via a potential-free contact on
terminals 8 and 9 – see enclosed circuit diagrams (max. 250V 1A, min. 5V DC 10mA):
the contact is open when the dryer is switched off or in an alarm condition, and closed when the dryer is switched on
and when the dew point is in accordance with the provisions.
OPERATING PRINCIPLE - When the dryer has been switched on, the electronic control unit indicates the current dew
point: the measured temperature is expressed in °C (● °C) with a resolution of 0,5°C, or in Fahrenheit (● °F) with a
resolution of 1°F.
PROGRAMMING
