Test readings, control module connections
| Test readings, control module connections |
| Remember |
| • |
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+).
