PASCOR ATLANTIC MO-10 Instruction Manual

INSTRUCTIONS FOR TYPE MO-10 MULTI-REVOLUTION MOTOR OPERATING MECHANISM
Instruction Booklet
IB-MO-10R July 2014
IMPORTANT
Read the entire manual before installing and maintaining equipment.
Make absolutely sure that applicable equipment is de-energized and properly grounded.

GENERAL
The MO-10 multi-revolution motor operator
mechanism will operate through 17 1/2 revolutions
and is designed to be used with a gear drive switch
operating mechanism. For applications requiring
fewer revolutions to complete an open or closed
cycle, simply adjust the auxiliary switch cams to
achieve the desired travel.
The MO-10 can be uncoupled from the vertical
operating pipe and test operated without disturbing
the position of the air-break disconnecting switches.
The uncoupled air-break disconnecting switches can
be padlocked in either the open or closed position.
For manual operation, insert the operating handle
through the opening in the front cover of the
housing. As the operating handle is inserted, the
motor is electrically disconnected from its control
voltage.
INSTALLATION INSTRUCTIONS
Fully close switch.
Mount the motor operator using the four
through holes and 5/8” hardware. Install the
Neoprene backed steel washers between the
enclosure and the structure with the Neoprene
side towards the motor operator.
The bottom of the vertical operating pipe should
be from 1/4” to 5/8” from the top of the fixed
coupling.
Drill the conduit plate, install conduit and
terminate control power wires. Refer to
drawings provided inside cabinet.
ADJUSTMENT STEPS
Set the motor operator in the CLOSED position.
If the motor operator is set for Counter-
Clockwise rotation to open, the CLOSED
position will typically be on the left and the
OPEN on the right facing the motor operator.
The opposite would be true for Clockwise to
open operation. The “close limit” Auxiliary
Switch 2 is to be set with switch closed and as
shown on the yellow instruction decal inside the
left door. After the cam has been rotated to the
desired position, use the 5/64” Allen wrench to
tighten the set screw until it contacts the shaft.
Tighten an additional ¼ turn for proper
torque.
With the switch and motor operator still in the
closed position, engage the uncoupling bar in
the fixed coupling slot and tighten the coupling
clamping bolts around the vertical operating
pipe. The ¼” aluminum spacer is provided to
help measure the ¼” clearance required between
the pipe coupling and the fixed coupling.

The spacer is to be discarded after the coupling
is clamped around the VOP. Do not tighten the
piercing bolts at this time since the relative
positions of the OPEN and CLOSED position
indicators may need to be moved.

NOTICE: IT IS RECOMMENDED TO USE SILICON ON THE BACK OF THE ENCLOSURE
WHERE IT MEETS THE STRUCTURE AFTER THE MO-10 HAS BEEN MOUNTED. THE FOUR
SEALING WASHERS ATTACHED TO THE MOUNTING BOLTS ON THE BACK OF THE MO-10
SHOULD BE PLACED ON THE BOLT BETWEEN THE STRUCTURE AND THE CABINET PRIOR
TO MOUNTING WITH THE NEOPRENE SIDE OF THE WASHER FACING THE CABINET.
Use the manual crank handle and crank the
switch to the fully OPEN position. Set the
“open limit” Auxiliary Switch 1 according to
the yellow decal.
Now that the “closed”, “open” and dynamic
brake auxiliary switches have been set and with
the switch still in the OPEN position, uncouple
the vertical operating pipe from the motor
operator. Slide the pin through the coupling so
that the uncoupling bar is held in the uncoupled
position.
Electrically operate the motor operator to the
CLOSED and back to the OPEN position. Try
to couple the VOP to the motor operator. The
uncoupling bar should slide freely into the slot
on the fixed coupling. If it does not, manually
crank the motor operator to where it does couple
freely and reset the “open” Auxiliary Switch 1.
Uncouple the VOP and repeat the process until
the uncoupling bar will operate freely without
manually cranking the motor operator.
Couple the VOP to the motor operator and
manually crank the switch to the fully CLOSED
position. Uncouple the VOP and electrically
operate the motor operator and adjust Auxiliary
Switch 2 until the uncoupling bar slides freely
into the fixed coupling slot.
Couple motor operator to the VOP and
electrically operate switch to verify appropriate
setting of the cams. Reset limit switches as
necessary.
Once successful switch operation is achieved
the remaining auxiliary switches can be set as
required.

individually set cams.
Braking of the permanent magnet motor is
accomplished through a braking resistor located
on the back side of the gear cover panel.
