1. Connect a cable between the “D“ pin and the “” pin on the status output
connector.
2. Connect a 1000 Ω resistor between the “+” pin and the pin for the status output that
is being tested.
3. Connect a voltmeter between the “D“ pin and the pin of the output being tested
(Table 7-10).
4. Under the DIAG / SIGNAL I/O menu (Section 4.13.2), scroll through the inputs and
outputs until you get to the output in question. Alternately turn the output on and
off.
The Voltmeter will read approximately 5 VDC when the output is OFF.
The Voltmeter will read approximately 0 VDC when the output is ON.
