The ten-turn speed adjustment knob on the control is used to change the travel speed of the
carriage. Adjusting the speed control may be performed when stationary or when in motion. The
travel speed may be preset, prior to any motion, by placing the Run/Stop switch to the Stop position
and the Forward/Neutral/Reverse switch in the Neutral position. Then, by rotating the Variable
Speed Control knob, the travel speed can be pre-set to the required value, as indicated in the
L.E.D. display.
= “VARIABLE SPEED CONTROL” - By turning the ten (10) turn rotary encoder knob
in a clockwise direction, the motor speed will be increased. When rotated in the
counter-clockwise direction, the motor speed will decrease. The Variable Speed
Control adjustment is used to set the travel speed of the “KAT” carriage in both
manual mode and automatic mode.
The Cycle Push Button is a momentary device, which allows the operator to toggle between
automatic and manual modes. The Cycle Push Button is also used to clear error codes
= “AUTOMATIC MODE” (“PRESET CYCLE ENABLED”) - Only by depressing the
Cycle Push Button continually for one second while the Fwd/Neut/Rev switch is in
the Reverse position, and while the control is in “Hold” (Stop) mode, may the Manual
Mode be toggled to the Automatic Mode (pre-set cycle routine enabled), as indicated
by the constant illumination of the Auto Cycle Mode L.E.D. The Cycle Push Button
is also used to enter and exit parameter/variable menu.
= “MANUAL MODE” (“PRESET CYCLE DISABLED”) - Only by depressing the Cycle
Push Button continually for one second while the Fwd/Neut/Rev switch is in the
Reverse position, and while the control is in “Hold“ (Stop) mode, may the Automatic
Mode be toggled to the Manual Mode (pre-set cycle routine disabled), as indicated
by the non-illumination of the Auto Cycle Mode L.E.D. The Cycle Push Button is also
used to enter and exit parameter/variable menu.
The L.E.D. Display
The GSP control has an L.E.D. display, which when factory installed on a “KAT” carriage, will be
calibrated to display the travel speed in one of two units of measure, either;
1. Calibration in inches per minute (IPM L.E.D. will be illuminated and the closed loop tach
feed back system is required) or;
2. Calibration in centimetres per minute (CM/MIN L.E.D. will be illuminated and the closed loop
tach feed back system is required).
Whenever the control is in Stop (hold) mode and there is no Forward or Reverse direction
commanded (Neutral), the speed display will indicate the preset speed.
For more information regarding the calibration scale selection, using the Motor Control Variables,
Rotary Switch, refer to the supplemental manual (GD-075) “Technical Information For The Gullco
“GSP-2100” Micro-Processor Based, 24 Volt DC Motor Control” (the pages are numbered with a
prefix of “T-“), attached at the end of this manual.
