Internal Auxiliary Switches
220736A,B Internal Auxiliary Switch kits can
be installed in TRADELINE models of Modutrol
IV Motors to control auxiliary equipment as a
function of motor shaft position.
220736A,B
■ The 220736A includes one Spdt Micro Switch V3
precision switch.
■ The 220736B includes two Spdt Micro Switch V3
precision switches.
■ Either kit can be installed in any Tradeline
Modutrol IV Motor.
■ Kits provide switch mounting bracket for easy
installation internal to motor.
■ The auxiliary switches are actuated by adjustable
cams inside the motor. These cams can be set to
actuate the switches at any angle within the stroke
of the motor. Only Modutrol IV TRADELINE
models are equipped with the cam assemblies for
actuating field-addable auxiliary switches. Switch
adjustment procedures are the same as that for
switches that come factory installed in Modutrol
IV Motor models.
■ Switch differentials of 1° or 10° can be selected.
■ Leadwires color coded to ease correct wiring of
auxiliary equipment.

SETTINGS AND ADJUSTMENTS
AUXILIARY SWITCHES
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.
AUXILIARY SWITCH ADJUSTMENT
PROCEDURE
WARNING
!
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 before 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 .
Setting and Adjustments
CAUTION
!
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
To turn the cams, insert small screwdriver (1/8" or
3 mm blade) through wiring box into slot on cam and move
the screwdriver at the top. Refer to Fig. 3. Each division on
the cam represents 15° of motor rotation.
A) Two position motors (M8185):
1. Turn off power and remove cover of wiring box.
2. Determine amount of shaft rotation, in degrees,
desired before switch is energized.
3. Note the position of the cam slots and, with screw-
driver, rotate the cam to the desired position for switch

stroke (in both directions). If necessary, repeat steps
4 and 6 for 1° differential, or 5 and 6 for 10° differential
until correct switching action is obtained.
7. Disconnect power from switches or quick-connect
terminals.
8. Connect auxiliary equipment to auxiliary switch
leads. See Wiring section.
9. Reconnect controller and power supply to motor.
10. Replace cover of wiring box.

Motors (M6184, M6194):
1. Turn off power and remove cover of wiring box.
2. Disconnect controller from motor.
3. Connect 24 Vac power and switches to drive motor
to position where auxiliary equipment is to be switched.
Refer to Fig. 8. Turn on power. Jumpering terminals R and
B will drive motor in the open direction, jumpering
terminals R and W will drive the motor in the closed
direction. To stop the motor at desired position,
disconnect jumpers. Motor will remain at this position
until connection is restored.
4. For switch differential of 1°, check continuity of
auxiliary switch N.O. (Red to Purple) contacts and rotate
cams as follows:
a. If contacts are open, rotate cam clockwise until
N.O. (Red to Purple) contacts close.
b. If contacts are closed, rotate cam counterclock-
wise until N.O. (Red to Purple) contacts open.
5. For switch differential of 10°, the cams must be
rotated approximately 180° prior to setting the switching
action. Refer to Fig. 3. Check continuity of the N.O.
(Red to Purple) contacts and rotate cams as follows:
a. If contacts are open, rotate cam counterclock-
wise until N.O. (Red to Purple) contacts close.
b. If contacts are closed, rotate cam clockwise until
N.O. (Red to Purple) contacts open.
6. Check for proper switch differential and switching
of auxiliary equipment by driving the motor through full
stroke (in both directions). If necessary repeat steps
4 and 6 for 1° differential, or 5 and 6 for 10° differential
until correct switching action is obtained.
7. Disconnect 24 V power and switches.
8. Connect auxiliary equipment to auxiliary switch
leads. See Wiring section.
9. Reconnect controller and power supply to motor.
10. Replace cover of wiring box.

WARNING
!
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 before 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.
Use the controller to run the motor fully open and then
fully closed. Make sure that the auxiliary equipment starts
and stops at the desired points in motor rotation. When
checkout is complete, return the controller to the desired
setting.
