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.
