13. IC contactor monitoring test.
a. With all power off disconnect wire #7 on the IC auxiliary terminal
#81.
b. Apply power with all SLS switches in the ON position. Turn one SLS
switch to OFF. The safe light should not come ON because the VSR
contacts K2 and K1 between terminals #13 and #14 should not
close. The VSR will not show a fault light.
c. Turn off power and reconnect wire # 7 at terminal #81 on the IC
contactor auxiliary.
d. Apply power and cycle the 4 SLS switches to confirm system
operation.
14. Voltage sensing test. The object is to determine whether the VSR
contacts K2 and K1 between terminals #13 and #14 remain open if a
voltage is present on the load side of the contactor.
a. To prepare, remove 3-phase power, primary and secondary fusing
and apply 120V to wire #1 and #2 to power control circuit. Also,
apply 3-phase voltage to load side of contactor.
b. All SLS switches in ON position.
c. Turn SLS switch (s) to off. With voltage above 10V applied to the
load side of contactor, the VSR should show a voltage hazard LED
and should not allow a SAFE light to come on.
Test is complete. Disconnect all power, remove metering, remove test
SLS switches, install Harting connectors for shipment, remove test
control panel, re-install primary and secondary fusing, check for loose
connections and check to see if all jumpers are removed.
