Monitoring
and Limiting
Devices
c. Lube oil pressure transmitter. Monitors lube oil pressure at the
last bearing oil nozzle. Pressure is shown on the GT Terminal
(figure 10). Indicates condition of the lube oil system, filter, and
the setting of the relief valve.
d. First stage discharge air temperature sensor. Temperature is
shown on GT Terminal (figure 10). Indicates condition of the
compressor first stage.
e. Second stage inlet air temperature sensor. Temperature is
shown on the GT Terminal (figure 10). Indicates condition of the
intercooler.
f. Second stage discharge air temperature sensor. Temperature is
shown on the GT Terminal (figure 10). Indicates condition of the
compressor second stage.
g. Lube oil temperature sensor. Temperature is shown on the GT
Terminal (figure 10). Indicates condition of the oil cooler.
h. Aftercooler discharge air temperature sensor. This is the
temperature of the air delivered to the air out service connection,
and is shown on the GT Terminal (figure 10). Indicates condition
of the aftercooler.
i. Total running time is shown on the GT Terminal (figure 10).
j. Total loaded time is shown on the GT Terminal (figure 10). An
accumulated count of loaded hours assists in tracking air usage
and available excess capacity.
k. Normal condition indication lights, on the Compressor Operator
Panel:
1. Standby
2. Run
3. Loaded
A lamp test is available using the GT Terminal, which tests all
indicating lights on the control panel, and the alarm beeper, if power is
on. This test does not affect normal compressor operation.
1.7
Alerts A blue ALERT light, and an appropriate message on the GT Terminal,
indicates that service is required or that a temperature prealarm exists
(temperature is approaching the shutdown point). In addition, an
audible alarm sounds when an alert occurs. The alarm may be
silenced without resetting the indication.
The GT Terminal indicates the following conditions as an ALERT:
a. Service inlet air filter. Indicates that the inlet air filter or the dust
filters are dirty, filter pressure drop exceeds 25 “H
2
O
b. Service oil filter. Indicates that the lube oil filter is dirty, filter
pressure drop exceeds 15 PSID.
c. Compressor service required. Indicates that 2 years have
elapsed since start-up, or the capacity control valve has cycled
1,000,000 times. Service must be scheduled.
d. Temperature prealarm (applies to all temperatures monitored).
Indicates that a temperature is approaching the shutdown point.
Refer to the appropriate paragraph of section 1.8 for details of
each monitored temperature. See page 22 for setpoint table.
