carriage. Therefore, all operator interface devices (except the power on/off isolation switch) are
subjected to signal level voltages only. Two Gullco GSP motor controls are used; one to drive the
“KAT”
®
carriage; and one to drive the motorized rack arm. These microprocessor pulse width
modulation motor controls offer operator interface of forward, stop, reverse and infinitely variable
control of the speed, within the range of the models, as well as an L.E.D. display indicating travel
speeds in either in/min. or cm/min. The travel speeds are electronically controlled using an optical
tachometer located on the back of each gear-motor. Through the use of this, closed loop, feedback
circuitry, each motor control can obtain accurate and constant speed control of the equipment when
running in any plane, regardless of the load (within the rating of the equipment).
INTENDED / FORESEEN USAGE
The Gullco “KAT”
®
carriage indexing system is used throughout the world to automate and improve
the quality and efficiency of single or multiple “head” overlay/surfacing operations.
Overlay/surfacing guns/torches are readily mounted on the end of the motorized rack arm, which is
mounted to the “KAT”
®
perpendicular to its travel direction. The “KAT”
®
track is positioned so that
the “KAT”
®
will move the gun (or torch) along the desired path, then usually secured in place using
magnetic or vacuum activated mounting devices. With the use of Gullco's “KAT”
®
carriage indexing
system, repetitive overlay/surfacing cycles may be performed, with precise motion of the gun/torch
from start to finish, regardless of the number of passes or the work pieces involved. Detrimental
factors such as poor or awkward accessibility, operator fatigue, or inconsistent workmanship are
eliminated. Required quality levels are consistently attained and productivity and profitability
increased.
OPERATION
The electrical and mechanical installation of the “KAT”
®
carriage indexing system is explained in the
Technical Manual.
Local Control Devices
The power On/Off switch is used to disconnect the power to the rest of the control circuitry.
I = On, O = Off.
WARNING! The motor control must not be continually
started and stopped by the removal and
reapplying of power to the control.
Turning the power off to the control will
not provide instant braking and continued
use will damage the control. Allow ten
(10) seconds after the removal of power
before reapplying the power to the motor
control.
The fuse holder allows accessibility to the main fuse by pushing the cap in towards the main body
and twisting in a counter-clockwise direction.
