GSP Control Overview
The “KAT”
®
carriage indexing system uses two (2) of Gullco’s sophisticated “GSP” microprocessor
motor controls (typically model GSP-2010-5 for the “KAT”
®
carriage and GSP-2010-7 for the
motorized rack arm).
“Cycle Control” – This microprocessor control is the Master control and is used to start and stop
automatic indexing cycles as well as allowing manual control of the cycling device that is used to
generate the repetitive forward and reverse motion (“KAT”
®
carriage
‡
). The part number for the
Cycle Control micro-processor chip is GSP-2004-5 (The part number for the normal GSP control
complete with this chip is GSP-2010-5). This control requires the following connections:
ƒ CN50 – Normal 24 VDC power supply.
ƒ CN21 – Motor leads of the cycling device.
ƒ CN11 – Cycling motor encoder connection.
ƒ CN13 – Cycling forward and reverse limit switch signals.
ƒ CN81
– Arc Signal Relay connection.
ƒ CN84 – Output signal to “Index Control” commanding an index.
ƒ CN12 – Input signals from “Index Control” identifying “ready” status and completion of
index.
“Index Control” – This microprocessor control is the slave control and is used to index the
overlay/surfacing gun/torch when commanded by the “Cycle Control” (at the end of each cyclic
pass), as well as allowing manual control of the indexing device (motorized rack arm
‡
). The part
number for the Index Control micro-processor chip is GSP-2004-7 (The part number for the normal
GSP control complete with this chip is GSP-2010-7). This control requires the following
connections:
ƒ CN50 – Normal 24 VDC power supply.
ƒ CN21 – Motor leads of the indexing device.
ƒ CN11 – Indexing motor encoder connection.
ƒ CN13 – Indexing forward and reverse limit switch signals.
ƒ CN84 – Output signal to “Cycle Control” confirming completion of an index.
ƒ CN83 – Output signal to “Cycle Control” confirming “Ready” status.
ƒ CN12 – Input signals from “Cycle Control” commanding gun/torch index.
Externally, the Gullco GSP controls have switching for Forward/Neutral/Reverse and Run/Stop, a
Manual/Auto or Full Speed Over-ride (& program variable increment/decrement) push button, a
rotary encoder for speed control, as well as a ten position selector switch for programming access
to the automatic cycle parameters/variables.
Please refer to the supplemental manual (GD-031) “Technical Information For The Gullco “GSP”
Micro-Processor Based, 24 Volt DC Motor Control” (the pages are numbered with a prefix of “T-“),
attached at the end of the Technical Manual, for additional, more comprehensive details than those
provided in the following overview.
‡
This manual makes the assumption that the “KAT”
®
carriage provides the cyclic motion, while the
motorized rack box provides the indexing motion. See the diagrams under “Special Reverse Indexing
Configuration” in the Technical Manual for details of how to reverse/alternate this arrangement.
