GT Terminal
(Figure 24)
Pilot lights, viewable from a distance, are provided for quick look
indication of operating conditions. An audible alarm is provided for
alarm annunciation. Pushbuttons are provided for specific control
functions, allowing continued compressor operation in the event that
the GT Terminal is off-line.
The GT Terminal is a touchscreen LCD monitor, showing operating
conditions, pressures, and temperatures. Messages to direct the
operator for service, pre-alarms, and shutdowns will be shown when
necessary. Required settings for pressure control, temperature
alarms, and control time delays are viewable and may be modified
using the touchscreen. The GT Terminal will automatically ‘dim’ to a
sleep condition if inactive, and awakens on any touch contact.

b. Page PG2 shows the operating temperatures of the compressor that
are monitored by the PLC. The temperatures may be displayed in
either °F or °C, selected by pressing the °F (°C) symbol.
c. Page PG3 shows the operating pressures of the compressor that
are monitored by the PLC. The pressures may be displayed in
either PSIG or Kg/cm2, selected by pressing the PSIG (Kg/cm2)
graphic block on the receiver picture.
d. Page PG4 shows elapsed times for compressor running hours and
for compressor loaded hours, and the load cycle count for service
scheduling.
Any of these pages may be assigned as the default page, which will
automatically show, after a delay, if no touch screen operations are
performed.
Detailed operating instructions are available in a separate document,
referenced by program version, i.e. “COP_HJ1B” is the operating
instructions for the Compressor Operator Panel / GT terminal using
program version HJ1B.
