Component Tests and General Diagnostics

Test Readings, Control Module Connections

Scope
The images below give readings and instructions for the measurement of signals and levels on the main unit and its control module.

Remember:
- Note the test conditions and use common sense when assessing the test result.
- First check that the control module has a power supply and is grounded.
- Then check all sensor inputs and signals from other systems.
- Finally check the control module outputs. Remember that the test readings do not indicate whether the actuator is working.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly.
- The test readings given apply to a calibrated Fluke 88/97.
- Test readings in % (+) and ms (+) show the pulse ratio and pulse duration of the signal. A test instrument capable of giving pulse ratio and pulse duration readings must be used. The sign indicates a positive trigger pulse, TRIG+.
