13.5.7.4.Status Outputs

The procedure below can be used to test the Status outputs:

1.Connect a jumper between the “D“ pin and the “” pin on the status output connector.

2.Connect a 1000 ohm resistor between the “+” pin and the pin for the status output that is being tested.

3.Connect a voltmeter between the “” pin and the pin of the output being tested (see table below).

Under the DIAG SIGNAL I/O menu (see Section 13.1.3), scroll through the inputs and outputs until you get to the output in question. Alternately turn on and off the output noting the voltage on the voltmeter, it should vary between 0 volts for ON and 5 volts for OFF.
