The display also shows the travel direction accessed as well as the status of the “Hold” (Stop)
command. Arc Signal activation 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 in 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 for more details.
The Arc Signal L.E.D. is used as an indication that the product/application specific
program has activated the output ports “CN81” and “CN83”. When the optional
Gullco auxiliary relay module is connected to the “CN81” port, the relay energizes,
providing an isolated signal activating the welding/cutting equipment as part of the
automatic cycle. 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 Auto Cycle Mode L.E.D. is used to indicate whether the control is in automatic
cycle mode (Preset Cycle routine enabled), or in manual mode (Preset Cycle routine
disabled). When the L.E.D. is constantly illuminated the automatic mode is enabled.
When the L.E.D. is not illuminated the control is in manual mode.
The various L.E.D.’s may also be used to help identify various program variable parameters and
their selected settings, when the Program Variable or Motor Control Variable selector switches are
accessed.
