High Temperature – The compressor is protected
from high discharge and separator temperature by two
independent thermistor probes. One probe is located
in the discharge housing to sense compressor dis-
charge air–oil mixture temperature. The second probe
is located at the separator discharge and senses the
temperature of the air at the oil separator. The ”Auto
Sentry–ES” will shut the compressor down if tempera-
ture sensed at either location exceeds 225
_
F. (or lower
per user adjustment) or if a rapid temperature rise is de-
tected. The location of the high temperature will be dis-
played. Shutdown will also occur if a shorted probe,
open probe, or extreme low temperature is detected.
The display will indicate the location of the defective
thermistor probe.
Machine damage will occur if the
compressor is repeatedly restarted
after high temperature stops opera-
tion. Find and correct the malfunc-
tion before resuming operation.
Separator Differential Pressure – The separator dif-
ferential pressure is continually monitored by the ”Auto
Sentry–ES.” At a differential pressure of approximately
15 psi, the unit will be shut down.
High Pressure – The ”Auto Sentry–ES” will shut down
the unit if excessive pressures are detected in the res-
ervoir or system. Shut down will occur if a defective
transducer is detected. The display will indicate the
location of the high sensed pressure or transducer
(xducer) error. Check that all adjustments have been
properly made, and all connections are secure.
Relief Valve – A pressure relief valve(s) is (are)
installed in the final discharge line and set to approxi-
mately 120% of the unit’s full load operating pressure
for protection against overpressure. Periodic checks
should be made to insure its (their) proper operation.
The relief valves should be tested for proper operation
at least once every year. To test the relief valve, raise
the system operating pressure to 75% of relief valve set
pressure and manually open the valve with the hand le-
ver. Hold the valve open for a few seconds and allow
it to snap shut.
