13. IC cont actor monito rin g tes t.
a. With all power off disconnect wire #7 on the IC auxiliary terminal
#81.
b. Apply power with all SLS switches in the ON posit ion. Turn one SLS
switch to OFF. The safe light s hould not come ON because the VSR
co nta c ts K2 and K1 be tw e en te rmina l s #1 3 and #1 4 s hou ld not
close. The VSR will not show a fault light.
c. Tu rn off power and reconnect wire # 7 at terminal #81 on the IC
contactor auxiliary.
d. Apply po wer 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 prepa re, remove 3-p hase pow er, prima ry and second ary fus ing
and app ly 12 0V to wi re #1 and #2 to po wer c on tro l circu it . Al so ,
apply 3- phas e voltage to load side of con tactor.
b. A l l SLS switc hes in ON p os ition.
c. Turn SLS switch (s) to off. With voltage above 10V applied to the
loa d side of contac to r, the VS R sh ould sho w a volta ge haza rd LE D
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
connecti ons an d check to see if all jumper s are rem ove d.
