OPERATION
Through the use of the optical tachometer closed loop feedback circuitry, the motor control can
obtain constant speed control of the cantilevered welding positioner, as well as determine the
amount of rotational distance travelled. The motor and the control operate on 24 VDC, supplied by
a power supply located in the base of the positioner tower. Therefore, all operator interface devices
(except the power on/off switch) are subjected to signal level voltages only.
The power On/Off switch is used to disconnect the power to the rest of the control circuitry.
I = on, O = off.
WARNING!
The motor control must not be continually started and stopped by the removal and
reapplying of power to the control. Turning the power off to the control will not
provide instant braking and continued use will damage the control. Allow ten (10)
seconds after the removal of power before reapplying the power to the motor control.
The fuse holder allows accessibility to the main fuse by pushing the cap in towards the main body
and twisting in a counterclockwise direction.
The direction selection switch allows the operator to set the manual direction of rotation. This is a
three (3) position switch with the center position being "Neutral" (no direction chosen).
WARNING!
Avoid changing the direction of rotation without making sure that rotation comes to a
complete stop first. Failure to comply may cause an overload.
