Test readings, control module connections
| Test readings, control module connections |
| Keep in mind: |
| • |
Note the test condition, and use common sense when assessing the test result.
|
|
| • |
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 which should be checked more thoroughly.
|
|
| • |
The test readings given apply to a calibrated Fluke 88/97.
|
|
| • |
The test readings show the signal pulse condition or pulse length. A test instrument with pulse ratio or pulse width measurement must be used.
