OPERATION
Through the use of the optical tachometer closed loop feedback circuitry, the motor control can
obtain constant speed control of the powered turning rolls. The motor and the control operate on
24VDC, supplied by a power supply located behind the control panel assembly. 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 following provides a brief description of the GSP-1000 control (refer to the sketch below):
