Test readings, control module connections
|
Values and directions for measuring signals and levels on the control module can be found on the following pages.
•
|
Note the test conditions, and use common sense when assessing the test results.
|
•
|
First check that the control module is supplied with current 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 that ought to be checked more thoroughly.
|
•
|
The test readings given apply to a calibrated Fluke 88/97.
|
•
|
The test readings show the signal's pulse ratio and pulse width. A test instrument with pulse ratio and pulse width measurement must be used. The sign indicates a positive trigger pulse, TRIG+.
