GTR-85 GENERATOR CONTROLLER
DESCRIPTION
The GTR series automatically starts and stops
generators during mains power failure when user
defined criteria are met. Operating status as well as
fault readout is clearly visible on the front panel LED’s
and or LCD display (GTR-8x GTR-9x)
Network connectivity is provided no matter how long
the distance. Monitoring and servicing to a much larger
clientele base. Instant monitoring services and
parameter setup to get your customers up and running
in the shortest possible time without even leaving the
office. An advantage for the service industry is the
real-time and simplified functionality and maintenance
of the GTR series controller. These features provide
fast and professional service.
Power source connectivity protection; a protective
circuit LED readout will indicate when reverse power
source connection is made. System protection is
assured. Anti-Crash watchdog circuitry and software
programming provide a real-time operating system that
corrects itself in case of unwanted interference in
program processing. Quick-Snap connectors prevent
wrong cable connections. Auto self-recovery fuses
protection for input/output current. (No replacement
necessary)
GTR units are constructed with a strong and appealing
cast aluminum casing. The sand blasted aluminum
finish creates a long lasting hard finish. Oxidation
treatment prevents rust and deterioration. Special slide
tray design protects the vital internal components.
The GTR series is a versatile generator/engine
controller equipped with all of the basic vital functions
found in most controllers on today’s market. The major
difference in our systems is the accessibility of the
system either from the control panel or from a remote
site via telephone line or broadband connection.

Rotary Switch Function:
‹ Off: Generator shutdown (no action).
‹ Manual: Operator controlled engine start up.
‹ ATS: Auto start function will be activated by
detecting shorted signal of terminal 17, 18.
‹ Network: Allows online authorized user entry for
monitoring and control. (Note: ATS is also functional
in this mode).
Push-Button Function:
Easy real-time monitoring and parameter setup are
accomplished through a network connection to the
control center. The GTR-85 controller is designed for
real-time generator/engine monitoring and control. Both
Analog and Digital readouts of system information are
visible on a personal computer through an RS-485
communication port. The GTR-85 is one model in a
series of GTR controller systems made by Monicon
Technology. It’s multi-functionality, compact size, easy
maintenance and lightweight make it possible to meet
your specific application requirements.
‹ Info. Page: Change LCD page for reading more
information.
‹ Light Test: Test lights for solid, clear, brightness
and alarm.
‹ Reset: First time “Reset” shutdown the alarm.
Second time “Reset” clears fault lights. Holding
down for a longer period will produce 1st and 2nd
time “Reset” functions
