Test Readings, Control Module Connections



Test Readings, Control Module Connections

Scope










The following images include values and directions for measuring signals and levels on the main instrument 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 specified test readings refer to those obtained with a calibrated Fluke 88/97.
- The test values %(+) and ms(+) indicate the pulse ratio and pulse duration of the signal. A test instrument for measuring pulse ratio and pulse duration must be used. The (+) sign indicates a positive trigger pulse, TRIG+.
