INDICATING CONTACTOR SWITCH (ICS)
(When Supplied)
No setting is required on the ICS unit except the
selection of the 0.2 or 2.0 ampere tap setting. This
selection is made by connecting the lead located in
front of the tap block to the desired setting by means
of the connecting screw. When the relay energizes a
125 volt or 250 volt d-c type WL relay switch, or
equivalent, use the 0.2 ampere tap. For 48 volt d-c
applications set ICS in 2 ampere tap and use
S#304C209G01 type WL relay or equivalent.
INDICATING VOLTAGE SWITCH (IVS)
(When Supplied)
No setting is required on the IVS unit except for the
selection of the required voltage tap on the tapped
resistor.
6.0 ADJUSTMENT AND MAINTENANCE
The proper adjustments to insure correct operation of
this relay have been made at the factory. Upon

receipt of the relay, no adjustments, other than those
covered under "Settings", should be required.
ACCEPTANCE CHECK
The following check is recommended to insure that
the relay is in proper working order:
A. CP UNIT
1. Contacts - Set the left-hand adjustable contact
in the center of the scale and adjust the voltage
until the moving contact just makes. Set the left-
hand contact back out of the way and bring the
right-hand contact up until the contacts just
make. The pointer should be within ± 1/32" of
where the left-hand pointer was.
2. Minimum Trip Voltages - Check the scale
markings by setting either of the two contacts at
a value marked on the scale, then alternately
apply this voltage plus 3% and minus 3%. Con-
tacts should make and break.
