DSE Model 71xx Series Control & Instrumentation System Mk2 Operators Manual
Part No. 057-113 71xx Series OPERATING MANUAL ISSUE 2 12/08/2010 ADM 53
SYMPTOM POSSIBLE REMEDY
Incorrect reading on Engine gauges
Fail to stop alarm when engine is at
rest Check engine is operating correctly. Check sensor and wiring.
Module appears to ‘revert’ to an
earlier configuration When editing a configuration using the PC software it is vital that the configuration is
first ‘read’ from the controller before editing it. This edited configuration must then be
“written” back to the controller for the changes to take effect.
When editing a configuration using the Front Panel Editor, be sure to press the Save
button to save the change before moving to another item or exiting the Front
Panel Editor.
Set will not take load Ensure the generator is available.
Check that the output configuration is correct to drive the load switch device and that
all connections are correct.
Remember that the set will not take load in manual mode unless a remote start on
load input is present.
Inaccurate generator measurements
on controller display The 71xx series controller is true RMS measuring so gives more accurate display
when compared with an ‘average’ meter such as an analogue panel meter or some
lower specified digital multimeters.
Accuracy of the controller is better than 1% of full scale. Ie Gen volts full scale is 333V
ph-n so accuracy is ±3.33V (1% of 333V).
NOTE:- The above fault finding is provided as a guide check-list only. As the module can be configured to
provide a wide range of different features, always refer to the source of your module configuration if in doubt.
