Measurement Value, REC (701)

Scope

Directions for the measurement of levels and signals at the REC and the measurement values are given on the following information.

NOTE: When measuring values at the pins the connector must remain plugged into the electrical centre. The pins can be accessed by lifting up the protective cover on the connector.

Remember:
- Pay attention to the measurement requirements, use common sense when judging the measurement result.
- Check first that there is a voltage supply to the control module and that it is grounded.
- Then check all sensor inputs and signals from other systems.
- Lastly check the outputs of the control module. Remember that the output values do not say anything about the functioning of the related actuator.
- If any measurement value is incorrect, use the wiring diagram to determine which cables, connectors or components should also be checked.
- The given measurement values are as measured with a calibrated Fluke 88/97.
- The measurement values %(+) and ms(+) show respectively the pulse ratio and the pulse length. A test instrument with pulse ratio and pulse width measurement must be used. The plus sign (+) denotes a positive trigger pulse, TRIG+.
