OPERATION
PAGE C − 2
D The liquid level devices (optional equip-
ment) operate in conjunction with the 3-po-
sition switch (HAND-OFF-AUTO) supplied
as part of that option. After the level sensors
and circuitry have been installed, pump op-
eration may be automatically controlled for
filling or dewatering functions (see LIQUID
LEVEL DEVICES, Section B).
Always terminate incoming power to the control
box before investigating control box circuitry prob-
lems.
Always terminate power to the control
box before performing service func-
tions.
Power through the control box may be terminated
by moving the tie handle to the OFF position, there-
by opening the circuit breakers. This stops the
pump, but does not terminate incoming power
through the field wiring connected to the control
box.
