6 Troubleshooting
When the connector cable is attached, the outputs at the frequency con-
verter are not free of voltage.
Before you start searching for the source of the problem, you should carry
out a few simple checks:
■
Is the TURBOVAC being supplied with electrical energy?
■
Are the connections . . .
- from the mains power cord to the frequency converter
- at the connector cable from the frequency converter to the mains net-
work in good working order?
■
If a water flow monitoring device is connected, is it functioning properly?
Check the water flow monitoring device by jumping its terminals and start-
ing the TURBOVAC.
■
Is the forevacuum pressure sufficient?
■
Is the vacuum chamber free of leaks?
Observe also the troubleshooting instructions for the frequency converter.
