1. Live circuits are exposed during auxiliary

switch adjustment procedure. Always turn off
power before adjusting switch cams.

2. Do not turn motor shaft by hand or with

wrench as damage to the motor can result.

NOTE:The following instructions are for normally closed

motors (motor shaft rotates clockwise, as viewed from
the power end of the motor, on an increase in signal).

Exact adjustment procedures vary for different

TRADELINE motor models. Find  your model on the
following list. Then proceed to the correct section for that
model.

SETTINGS AND ADJUSTMENTS

The auxiliary switches are spdt switches that are actu-

ated by adjustable cams. The cams are factory mounted on
the motor shaft at the power end of the motor. The settings
of the cams determine the point in motor shaft rotation at
which the auxiliary equipment will be switched on or off.
These cams can be set to actuate the switches at any angle
within the stroke of the motor. All TRADELINE motors
include auxiliary switch cams which permit installation of
this auxiliary switch kit (220736A, 220736B).

NOTE: When the slow-rise portion of the cam is used, the

switching differential is approximately 10

°

 of rotation.

When the fast-rise portion of the cam is used, the switch
differential is approximately 1

°

 of rotation. Do not use

the fast rise portion of the cam if fast cycling of
auxiliary equipment is undesirable.

FIRE OR EXPLOSION HAZARD
CAN CAUSE SEVERE INJURY OR DEATH

When auxiliary switches control combustion
equipment, incorrect wiring of the switches can
allow the burner to come on at high fire. Check
auxiliary switch wiring and cam adjustment be-
fore turning on the system. Watch the controlled
equipment through one complete cycle. Shut the
system down immediately if switches do not
correctly sequence the equipment .
