  • Confirm wiring is properly attached to the terminals.
  • Ensure that voltage is within 2-10 VDC range. Using a voltmeter, measure DC voltage from 203-400 for system transducer and 204-400 for suction transducer. Anything less than 2.0 V or greater than 10 V DC indicates a faulty transducer or faulty wiring.

From main screen touch MENU, then CONFIG SYSTEM and SYSTEM SETTING. Verify maximum ranges shown for suction and system pressure transducers match the actual ranges of the installed transducers.
