The following pages contain readings and instructions for measuring signals and levels on the main instrument unit and its control module.
Remember
-
Note the test conditions and use common sense when assessing the test result.
-
First check that the control module has a power supply and is grounded.
-
Then check all sensor inputs and signals from other systems.
-
Finally, check the control module outputs. Remember that these readings are not an indication that the actuator is in working order.
-
If a reading is not OK, consult the wiring diagram to trace the leads, connectors or components which should be checked more thoroughly.
-
The specified test readings are based on the use of a calibrated Fluke 88/97.
-
Readings %(+) and ms(+) indicate the signal pulse ratio and pulse width respectively. A test instrument with pulse ratio and pulse width
measurement must be used. The sign (+) indicates a positive trigger pulse, TRIG+.
