Gullco GK-200-RL - Manual (Page 37)

The display also shows the travel direction accessed as well as the status of the “Hold” (Stop)
command. Weld activation signal and Program/Cycle mode L.E.D.’s are also provided.
The Forward and Reverse L.E.D.’s indicate the motor direction commanded.
The “Hold” (stop) L.E.D. will illuminate whenever there is a “Hold” (stop) command
present. This could be any combination of either the Run/Stop switch being in the
Stop position, or a “Hold” (stop) command being activated through one of the
interface ports, or a part of the automatic cycle. When the “Hold” (stop) L.E.D.
flashes on and off, it is indicating that the control is looking for a reset before allowing
any functionality. To reset this condition, initiate a “Hold” (stop) command through
the Run/Stop switch or one of the interface ports. See the section regarding error
codes, earlier in the manual for more details.
The Arc Signal L.E.D. is typically used as an indication that the product/application
specific program has activated the output ports “CN81” & “CN83” (The “-2” program
activates “CN82” & “CN84”). When a Gullco auxiliary relay module (optional on most
equipment) is connected to the “CN81” (or “CN82”) port the relay energizes,
providing an isolated signal activating the welding/cutting equipment. When the
“CN81” port is de-activated, the relay is de-energized, instructing the welding/cutting
equipment to stop and the Arc Signal L.E.D. is extinguished.
The Pre-set Cycle L.E.D. is used to indicate whether the Preset Cycle routine is
enabled (automatic cycle mode) or disabled (manual mode). When the L.E.D. is
constantly illuminated the Preset Cycle is enabled (automatic cycle mode). When
the L.E.D. is not illuminated the Preset Cycle is disabled (manual mode).
Local Control Operation
The following provides some basic operational procedures that are typical on the GSP-2100 control.
It is important to note that depending upon the product/application specific program, some of the
following information may vary or not be applicable.
SPEED PRESET - 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.
MANUAL MODE – To place the control in manual mode (disable the preset cycle), with the power
on, place the Run/Stop switch in the Stop position and Fwd/Neut/Rev switch in the Reverse
position. Then continually press the Cycle Push Button until the display shows “Hnd” (the Pre-set
Cycle L.E.D. will be extinguished). While the control is in manual mode, the motor may usually be
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 or activated limit switch signals etc., 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 manual
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.
AUTOMATIC MODE - To place the control in automatic mode (enable the preset cycle), with the
power on, place the Run/Stop switch in the Stop position and Fwd/Neut/Rev switch in the Reverse
