Honeywell 220736B User Manual

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.

operate the switches at any point in the motor stroke.
220736A—Includes one Spdt Micro Switch V3

snap acting switch, mounted on left side and

operated by outer cam.
220736B—Includes two Spdt Micro Switch V3

snap acting switches.

SWITCH DIFFERENTIAL (difference between switch

make and break points): Approximately 1 or 10 de­grees, determined by cam setting.

CAUTION

!

Disconnect power supply before beginning in­stallation to prevent electrical shock or equip­ment damage.

NOTE: The wire colors of the 220736A,B auxiliary

switches are different from those of factory installed
auxiliary switches. See Tables 1-3 and Fig. 2.

nal motor model number and refer to Tables 1-3.

2. From the appropriate table, determine switch
leadwire color coding and configuration (N.O. and N.C.
contacts).

between the replaced motor and field addable switch color
coding.

4. Disconnect and remove the motor to be replaced.

5. Remove the cover from the wiring box of the
TRADELINE Modutrol IV motor.

6. Check motor for proper stroke setting. Adjust stroke
as needed. Refer to motor specification sheet.

7. Position the switch assembly above the motor as

the two mounting screws, making sure the switch follow­ers are properly aligned with the inner and outer cams in
the motor. The 220736A includes only the switch for the
outer cam.

9. Run all switch leadwires through slots to line volt­age section (at auxiliary end of motor), where connections
to auxiliary equipment should be made with solderless
connectors.

CAUTION

!

The auxiliary switches in the Series 91 low and
medium torque TRADELINE Modutrol IV Mo­tors operate opposite to those in the Modutrol
motors listed in Tables 1 and 2, page 4. When
wiring the switches, connect the new switches to
the controlled equipment as shown in the appro­priate table.
