Perform this test with the starter open and appropriate
lock-out procedures.
Connect a 20 k

resistor between one phase and ground
at the line side of the starter or motor terminal box. Select
a phase that is not connected to PGR-3200 terminal 2 (or
the
PGH-5000 or PGH-6000). The
PGR-3200 will indicate a warning by lighting the 50 k

and 30 k

LED’s and energizing the 50 k

insulation
relay.
Replace the 20-k

resistor with an 8 k

resistor.
The PGR-3200 will indicate an alarm by lighting the
< 10 k

LED and energizing the 10 k

insulation relay.
