Unpack the mechanism and check for damage. If damage is found, file a claim with the carrier immediately
and notify the factory.
Figure 1 - Part Identification
Storage:
If this equipment is to be stored prior to use:
1. Store the VM-1 mechanism in the upright position
2. The door should be latched closed
3. No part of the mechanism should be submerged
4. Indoor storage or covering with a tarp is not necessary, but preferred. As with all electrical
equipment, however, condensation is a consideration.
5. The heater should be energized if the mechanism is stored outdoors for an extended period (3+
months) or in a humid environment. Refer to wiring diagram drawing for heater connection.

Installation and Adjustment Procedures

Static brake
The static brake is an electro-mechanical mechanism comprised of a brake pad, brake arm, spring and solenoid.
The spring provides the mechanical force necessary to depress the brake and keep the motor operator from
turning. When the motor is energized, the brake solenoid, seen in Figure 1, depresses the spring thereby
releasing the brake and allowing the motor operator to function.
Dynamic brake
The dynamic brake is a strictly electrical device. A set of contacts runs parallel to the motor which is normally
closed. When the operator needs to be stopped, a short is induced across the motor operator which therefore
stops the operator from rotating.
Installation Note: Installation consists of mounting and adjusting the VM-1 Motor Mechanism to coordinate
with the switch operating controls. Sketches and dimensions contained in this manual are for illustration only.
Refer to unit assembly drawing and operating mechanism drawing for specific dimensions.
Application Note: The VM-1 Motor Mechanism is equipped with an adjustable rotation lock that provides
variable starting and stopping points on a rotational angle between 30° and 330°. Refer to section VIII for
adjustment of this lock.
Caution: Use manual operation for installation. Do not perform electrical operation until all
adjustments are complete. Keep away from moving parts. Keep away from electrical
components unless power has been disconnected.
Installation:
1. Mount the VM-1 Mechanism as shown on the Operating Mechanism Drawing or Mounting
Arrangement Drawing. Refer to Switch Installation Instructions for switch adjustment.
2. Attach the upper decoupler member to the vertical pipe in accordance with the instructions provided
for the decoupler type supplied.
3. Universal Decoupler (Not Common)
●Do not drive in the self-piercing set screws at this time.
●The vertical pipe should bottom out in the lower decoupler section for 1-1/2 inch pipe and in the
upper decoupler section for 2 inch pipe.
●Discard cap and hardware for the unused section.
●A clearance of ½ inch must be maintained between the upper and lower decoupler members. To
adjust, raise or lower the vertical pipe in the vertical bearing at the top of the pipe. The full pipe weight
must be supported by the vertical bearing.
●When required clearance is achieved, pierce the pipe with the set screw in the pipe collar above the
vertical bearing.
●It may be necessary to pre-drill all set screw holes, using the threaded drill guides if provided.
●Refer to Figures 2 and 3 for decoupler operation. Use the decoupler key to align the upper decoupler
member with the fixed rotation lock and tighten clamping bolts. Do not pierce the pipe with set screw
at this time.

4. Single Size Decoupler:
●Do not pierce the pipe with the self-piercing set screws at this time.
●The vertical pipe should bottom out in the upper decoupler member.
●A clearance of ½ inch must be maintained between the upper and lower decoupler members. To
adjust, raise or lower the vertical pipe in the vertical bearing. The vertical bearing must support the full
weight of the pipe.
●When required clearance is achieved, pierce the pipe with the set screw in the collar above the
vertical bearing. (Do not drive set screw into coupling yet)
●If heavy wall pipe is used it will be necessary to pre-drill all set screw holes, using the threaded drill
guides when provided.
●Refer to Figure 3 for decoupler operation. Use the decoupler key to align the upper decoupler
member with the fixed rotation lock. Tighten the clamping bolts. Do not pierce the pipe until proper
switch operation has been confirmed.

C. VM-1 Decoupled- Switch is locked out
Figure 3 - Decoupler Operation
Decoupler Operation: If decoupler key is hard to remove, use crank handle or swing
handle to back off torque load. The key should have
adequate clearance between the lower decoupler member
when the key is in the decoupled (locked out) position.
Electrical Check-Out Procedure:
1. Although electrical operation of the switch should not be attempted until later, the VM-1 mechanism
can be checked electrically now with the VM-1 decoupled from the switch
2. Decouple as shown in Figure 3 and connect the VM-1 mechanism for electrical operation as shown on
the wiring diagram drawing. Refer to Figure 1 for conduit entry into the cabinet.
3. Proper rotation is set at the factory, however adjustment may be required. Test each mechanism to
confirm rotation output agrees with the operating mechanism drawing. It is recommended the
decoupled VM-1 be hand cranked to the midpoint of rotation before the initial test operation. Use the
push buttons for testing operation.
4. OPEN and CLOSE push buttons (if supplied) initiate electrical operation.

Installation and Adjustment Procedures

5. STOP button (if supplied) overrides all other commands, sets the brake and halts mechanism
operation.
6. The motor fuses (or circuit breakers) must be in place for electrical operation.
7. In event of motor overload: (When Supplied)
The thermal overload relay will trip.
Remove cause of overload.
Allow motor to cool until it reaches normal operating temperature.
Reset the thermal overload relay by flipping the motor switch to the OFF position, and
then back to the ON position.
Use the OPEN and CLOSE push buttons to resume electrical operation.
8. If over or under rotation is observed, adjust the motor limit switches as directed in Auxiliary Switch
Adjustment: Page 11
Caution: Before performing any maintenance or adjustment inside the VM-1 housing, make
sure the circuits are de-energized.
Adjusting Switch Operation to VM-1 Rotation:
1. Adjust the switch operating mechanism to match the specified rotation of the VM-1 mechanism by
adapting the length of the adjustable arm at the top of the vertical pipe. Refer to the Operating
Mechanism drawing and switch installation instructions for this procedure.
2. Perform all trail operations manually. Refer to Figure 4.
3. Do not rotate the VM-1 past the open and/or close position locks. Over rotation can damage the switch
and operating mechanism.
4. The motor safety switch automatically disconnects the motor from the line voltage when the manual
crank handle is inserted.
5. Removal of the manual hand crank automatically reconnects the motor with the line voltage.
6. Refer to switch installation instructions for adjustment procedures of the operating mechanism. During
switch adjustments, use the position stops (if supplied) as reference points for fully open and fully
closed.
