OPERATION
Step 4: Preliminary Checks Before Starting
1. Before starting the control, check all fuses, connections, and adjustments such
as horsepower switch settings.
2. Check all rotating members. Be sure keys, pulleys, etc. are securely fastened and
safety guards are in place.
3. Check for proper mounting and alignment of products, and verify safe loading on
shafts and gears.
4. Check that motor is securely mounted.
5. Test the motor unloaded first to verify proper connections.
Step 5: Operating the Control
1. With AC power switch OFF, set the speed pot to ZERO (fully counterclockwise).
2. Turn the AC power switch ON.
3. Turn the speed pot until motor rotates at desired speed. Note that “SCR rated”
motors, or motors rated 90 VDC, will run faster with a filtered control because of
the 130 VDC max. output voltage.
4. If the motor does not start promptly and run smoothly, turn the AC power switch
OFF, unplug the control, and refer to “TROUBLESHOOTING,” below.
Step 6: Internal Adjustments
Most users will find the factory calibration of the control to be acceptable for
their application. For those who want to fine-tune the control, five trim pots are
accessible on the PC board. First, remove the enclosure cover.
Figure 4
shows the
locations of the internal adjustment potentiometers.
WARNING–
Use a non-metallic or insulated adjustment tool for internal
adjustments. Circuit components are at high potential and accidental short-
circuiting and shock hazard may occur with conductive tools.
TROUBLESHOOTING
WARNING–
Disconnect the control from the AC power source before working on
the control, motor, or driven equipment.
If the motor does not operate, disconnect the AC power and double check all
connections and fuses. Make sure the TORQ pot is not turned fully counterclockwise.
If a fuse is blown and the motor is not locked (stalled) or overloaded, do not replace
the fuse. The control may be damaged. If the motor is overloaded, reduce the load
and replace the blown fuses with new ones of the proper type and rating. If the
problem persists, contact your source of purchase or a Bodine Authorized Service
Center and describe the problem in detail. Include all nameplate data for both motor
and control.
MOTOR CONNECTIONS–
Feed the motor cable through the opening in the bottom of
the enclosure. For clockwise armature rotation, connect the “+” motor wire (white
wire on Bodine motors) to terminal “A2” and the “–” motor wire (black wire on
Bodine motors) to terminal “A1”. For counterclockwise rotation, reverse the motor
connections. Reinstall enclosure cover.
LINE FUSE–
Models 0790 and 0791 are equipped with a fuseholder on the front
panel that is accessible to users for field replacement of the fuse. A four amp
fuse is factory installed in model 0790 and an eight amp fuse is factory installed
in model 0791.
AC POWER CONNECTIONS–
Models 0790 and 0791 are equipped with a six foot long
cable having a standard connector for 115 VAC outlet. When all other connections
are made, plug it in.

BODINE LIMITED WARRANTY
The Bodine Electric Company warrants all products it manufactures to be free
of defects in workmanship and materials when applied in accordance with
nameplate specifications. Bodine motors and gearmotors purchased with
and used only with appropriately applied Bodine controls are covered by this
warranty for a period of 24 months from the date of purchase or 30 months from
date of manufacture, whichever comes first. Bodine motors and gearmotors
used with non-Bodine controls and Bodine controls used with non-Bodine
motors and gearmotors are covered by a 12 month warranty period. The Bodine
Electric Company will repair, replace, or refund at its option, any of its products
which has been found to be defective and within the warranty period, provided
that the product is shipped freight prepaid, with previous authorization, to Bodine
or to a Bodine Authorized Service Center. Bodine is not responsible for removal,
installation, or any other incidental expenses incurred in shipping the products
to or from Bodine. This warranty is in lieu of any other expressed or implied
warranty–including, but not limited to, any implied warranties of merchantability
and/or fitness for a particular use. Bodine’s liability under this warranty shall
be limited to repair or replacement of the Bodine product and Bodine shall
not be liable, under any circumstances, for any consequential, incidental or
indirect damages or expenses associated with the warranted products. Proof
of purchase of motor or gearmotor and matching control as a system must be
provided with any claim.
MINIMUM SPEED LIMIT–
Turn the MIN pot clockwise to make the motor run faster
than 0 rpm when the speed pot is set at “0”. With the MIN pot fully clockwise
and the speed pot set at “0” output voltage will be about 50 VDC. Increasing the
minimum speed will also increase the maximum speed, so the MAX pot may need
to be adjusted.
MAXIMUM SPEED LIMIT–
Turn the MAX pot counterclockwise to make the motor
run slower than full speed when the speed pot is set at “100”. With the MAX pot
fully counterclockwise and the speed pot set at “100” the motor will run at about
60% of full speed.
TORQUE LIMIT–
Turn the TORQ pot counterclockwise to reduce the peak torque
capability of the motor. Most Bodine motors will produce about 200% of rated
torque with the horsepower switches set per
Figure 2
and the TORQ pot turned
fully clockwise. The motor must be properly sized for the application so that
it only produces this peak torque intermittently. Turning the TORQ pot fully
counterclockwise will produce 0% torque (stall).
ACCELERATION/DECELERATION TIME–
Turn the ACC pot to simultaneously adjust
the acceleration and deceleration time within the range selected by dip switches
7 and 8. Refer to
Figure 3.
Clockwise rotation of ACC pot increases acceleration or
deceleration time.
SPEED REGULATION–
The REG pot sets the gain of the IR compensation. It is factory-
set so that the speed of most Bodine motors varies no more than 2% from no load to
full load at full speed when the horsepower switches are set per
Figure 2.
The REG
pot normally requires no adjustment by the user unless better speed regulation is
needed or no speed regulation is needed. Turn the REG pot clockwise to increase IR
compensation. Turning it too much will make the system unstable. If this happens,
turn the REG pot counterclockwise to reduce the IR compensation. When using the
WPM control in a closed-loop system with another control device, turn the REG pot
fully counterclockwise to eliminate IR compensation.
