Test Readings, Control Module Connections

Scope





The following pages include values and directions for measuring signals and levels on the main instrument unit and its control module.

Remember
^ Note the test conditions, use common sense when assessing the test results.
^ First check that the control module is supplied with current and is grounded.
^ Then check all the sensor inputs and signals from other systems.
^ Lastly, check the control module outputs. Remember, the test values do not say anything about whether or not the actuator is in working order.
^ If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.
^ The test readings indicated are in respect of 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+.
