INDICATING CONTACTOR SWITCH
(ICS)
Close the main relay contacts and pass suf
ficient de current through the trip circuit to close
the contacts of the ICS. This value of current
should be not less than 1.0 ampere nor greater
than 1.2 amperes for the 1 ampere ICS. The
current should not be greater than the particular
ICS tap setting being used for the 0.2-2.0 ampere
ICS. The operation indicator target should drop
freely.
The contact gap should be approximately
0.047" for the 0.2/2.0 ampere unit and 0.070" for
the 1.0 ampere unit between the briding moving
contact and the adjustable stationary contacts.
The bridging moving contact should touch both
stationary contacts simultaneously.
RENEWAL PARTS
Repair work can be done most satisfactorily at
the factory. However, interchangeable parts can
be furnished to customers who are equipped for
doing repair work. When ordering parts, always
give the complete nameplate data.
