Test readings, control module connections
|
The following pages contain values and instructions for obtaining readings of signals and levels on the control module.
•
|
Note the test conditions and use your common sense when judging the test results.
|
•
|
First check that the control module is supplied with current and grounded.
|
•
|
Then check all sensor inputs and signals from other systems.
|
•
|
Check the control module outputs last. Remember that the test readings do not indicate whether or not the actuator is working.
|
•
|
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 given apply to a correctly calibrated Fluke 88/97.
|
•
|
The readings indicate the pulse ratio and pulse duration of the signal. A test instrument capable of measuring both pulse ratio and pulse duration must be used. The + sign denotes a positive trigger pulse (TRIG+).
