Wiring And Adjusting The Switch Operator; Before Starting - S&C Mark VI Instructions For Installation Manual

WIRING AND ADJUSTING THE SWITCH OPERATOR

Before Starting

Make sure the Mark VI CS-1A Switch Operator
is securely attached to the structure and that the
vertical shaft is attached to the coupling on the
output shaft of the switch operator.
The factory-installed jumpers should be in
place between the interrupter contacts. See
Figure 42.
NOTICE
DO NOT remove the jumpers until directed
to do so in the following instructions.
DO NOT wire the interrupters and charging
motors to the Mark VI CS-1A Switch Operator
until directed to do so in the following
instructions.
Two tagged temporary jumpers have been
installed inside the Mark VI CS-1A Switch
Operator between the interrupter "a" con-
tacts and the "b" contacts. These jumpers
bypass the interrupter trip solenoids allow-
ing adjustment and checkout of the operator
before the interrupters and charging motors
are wired into the circuit. (The motors take
two minutes to close and reset the interrupt-
ers between operations.)
