T-5
= “REVERSE” - When the switch is in this position, the control will drive the motor in
the Reverse direction when so permitted.
= “VARIABLE SPEED CONTROL” - By turning the ten potentiometer knob in a
clockwise direction, the motor speed will be increased. When rotated in the counter-
clockwise direction, the motor speed will decrease.
Local Control Operation
The control is operated by placing the Forward/Neutral/Reverse switch in the desired travel
direction, and placing the Run/Stop switch in the Run position. Normally, if there are no other
external “Hold” (stop) signals, direction signals or speed signals, the motor will run in the direction
selected at the speed set by the Variable Speed Control Knob. The speed may be adjusted at any
time and the motor motion may be stopped by placing either the Run/Stop switch in the Stop
position or by placing the Forward/Neutral/Reverse switch in the Neutral position.
If an external “Hold” (stop) signal is being used (e.g. Run/Stop footswitch), the motor will only be
allowed to run when: the speed adjustment knob is set to a value greater than zero: the Run/Stop
switch is in the Run position: the Forward/Neutral/Reverse switch is either set to Forward or
Reverse; and the external “Hold” (stop) signal is released (i.e. Run/Stop footswitch is activated).
If external direction signals are being used (e.g. Forward/Neutral/Reverse footswitch), the motor will
run in the direction set by either the direction switch located on the “GSP-1000” control or by the
external direction signal. In the event of directional conflict (i.e the local direction toggle switch is
requesting a directional command opposite to that of an external direction command) the control will
terminate and/or prohibit motor output until the conflict is cleared.
If an external speed signal is being used (e.g. Variable Speed footswitch), the motor will rotate at
the speed set by the external speed signal up to the maximum speed set by the Speed Adjustment
potentiometer. For example, if the Speed Adjustment potentiometer of the “GSP-1000” control was
set to 47% of full speed, then the external speed signal could control the motor speed from zero (0)
up to 47% of full speed.
