Troubleshooting
5.1
Digital Display Not Illuminated When Indicator Is Switched On
[1]
Check the incoming mains supply and fuse.
[2]
(
There are no internal fuses which can be replaced
)
5.2
Verify The Transducer Connections
[1]
Measure the transducer excitation supply voltage between terminals (negative) 1 & 2 (linked) and
between positive 5 & 6 (linked) and that it is correct for the type of transducer. (5v for Cleveland
Kidder Classic and Ultra series, and 10v for foil type transducers). In addition, measure the
differential millivolt signal at full transducer load to ensure that the unit is given signals within its
correct working range.
5.3
Check The Display Is Reading Correctly When The Transducers Are Loaded
[1]
Check the wiring connections to the transducers, interconnecting cables, and mechanical
mounting of the transducers.
[2]
Check the resistance values of the transducers, as explained in the transducer section of the
handbook.
[3]
Zener Barriers (if fitted) may also need to be checked that they are correct.
[4]
Try the re-calibration procedure above.
[5]
An exchange unit is available from CMC Controls.
