Operator’s <strong>Manual</strong><br />
Trouble Cause Remedy<br />
Electric Control System (optional)<br />
Control does not switch on No control voltage Check feed line<br />
Thermal overload relay for drive<br />
motor triggered<br />
Control does not switch off, final<br />
pressure safety valve blows off<br />
Electronic Control (optional)<br />
Electronic Control shuts off unit before<br />
40 seconds have elapsed<br />
Electronic Control indicates fault although<br />
all monitored items are ok<br />
Electronic Control indicates fault although<br />
operating parameters are ok<br />
Automatic Condensate Drain (optional)<br />
Control fuse defective Replace fuse, eliminate cause<br />
Control current line cut off, line or<br />
terminal loose<br />
Tighten terminal<br />
Thermal overload triggered Clear faults as described in the following<br />
Current consumption too high Check compressor drive<br />
Overload relay set too low Correct setting, check current consumption<br />
of each phase<br />
Final pressure switch set too high Correct setting<br />
Final pressure safety valve defective<br />
Replace safety valve<br />
Timing circuit defective Replace Electronic Control<br />
Wire to monitored item broken Repair wiring<br />
Sensor defective Replace sensor<br />
Drain valves do not close No control air Check control air line<br />
Drain valves leaking due to dirt Dismantle drain valve and clean<br />
Drain valves do not open Condensate drain valve piston jammed<br />
Dismantle drain valve, clean or replace<br />
valve<br />
Solenoid valve does not close Solenoid valve faulty Check solenoid valve and replace if<br />
necessary<br />
No electrical signal Check electrical control circuit and<br />
timer<br />
Solenoid valve does not open Solenoid valve faulty Check solenoid valve and replace if<br />
necessary<br />
Unsatisfactory drainage (lot of condensate<br />
from manual valves)<br />
Continuous electrical signal Check electrical control circuit and<br />
timer<br />
Nozzle in 3rd or 4th stage drain<br />
valve clogged<br />
Remove nozzle, clean<br />
