Part 5 Maintenance
5.2.5 Stopping CA-dryer
during operation:
Cause
- Stopping of CA-dryer by
installed electric start and
protection device (Klixon) at
the refrigerant compressor
due to overload
5.2.5.1 CA-volume flow too
high
5.2.5.2 CA-inlet temperature
too high
5.2.5.3 Room temperature too
high
5.2.5.4 Defective fan or cooling
water regulator (water-
cooled version)
5.2.5.5 Condenser polluted
5.2.5.6 Operating pressure too
low
Remedy
- eliminate cause of trouble, see 3.5 or call for service
- the CA-dryer will return to operation mode automati-
cally after protection device has cooled down.
Note: The immediate restarting of the unit is not pos-
sible because the protection device requires a mini-
mum time to cool down to an admissible operating
temperature.
Reduce volume flow
Check whether CA-dryer´s capacity is properly selected,
increase CA-dryer´s capacity
Check aftercooler with separator and drain behind the
compressed air compressor, install if not present
Ensure proper ventilation of CA-dryer´s location
Replace fan or cooling water regulator resp., call for serv-
ice
Clean condenser
Increase operating pressure, check whether CA-dryer´s
capacity is properly selected
