2.
Using a multimeter, check that all output relays are de-energized (i.e. N.O. contacts open, N.C. contacts closed).
3.
Make the following setting change:
4.
Check that the Trip output is energized (i.e. N.O. contacts closed), and the Trip LED is illuminated.
5.
Make the following setting change:
6.
Repeat Steps 3 through 5 for Output Relays 2 through 8 inclusive.
7.
Observing polarity, connect a minimum 5 V DC source in series with a limiting resistor that will permit a minimum cur-
rent of 100 mA, in series with the Solid State output. Observing polarity, connect a DC voltmeter across the limiting
resistor. Check there is no voltage displayed on the voltmeter.
8.
Change setting to:
9.
Check that a voltage has appeared on the voltmeter. Turn off the source and disconnect the test wiring.
