SECTION 2
AUTO SENTRY OPERATION
OPERATING THE COMPRESSOR
The two keys on the left side of the keypad control the operation of the controls. Prior to starting, press
the [STOP/RESET] key to place the controller into its READY state (as indicated on the display). Press
the [RUN] key to start compressor operation. The green LED will light near the automatic operation
symbol whenever operation is enabled. Once operating, the selected operating mode is displayed in the
lower right corner of the message window.
Press the [STOP/RESET] key at any time to stop the compressor under normal conditions. If the
compressor has been running, the reservoir will first be relieved of pressure before stopping the motor.
The display will count down to zero during the normal stop.
WARNING
Automatic restarting or electrical shock can cause injury or death. Open and
lock main disconnect and any other circuits before servicing unit.
While operating and running, the unit may be manually unloaded by pressing and holding the [RUN] key.
This unloads a running compressor after several seconds, and will prevent loading while the key is held
down. When the key is released, the control resumes its normal operation as required.
An optional control may be wired into the controller to interrupt and restart the unit based on controls by
others. When stopped by these controls, the display indicates “REMOTE HALT”.
In any mode, the compressor will start only if reservoir pressure is below 5 psig. The display will indicate
if the control is waiting for a reservoir blowdown, along with the remaining pressure. The controls also
delay initial loading of the compressor until a startup delay has been completed.
AUTO SENTRY CONTROL DISPLAY
The display above the keypad provides operating information to the user. If a shutdown has occurred,
the display indicates the cause.
During normal operation, the display shows the system (plant) pressure, compressor discharge
temperature, total running hours, and operation mode. Alternate displays are available by pressing the
keypad cursor [<][>] keys, and will be identified on the display. These include:
1. Air/oil reservoir pressure
RES PRES
2. Separator differential pressureDIF PRES
3. Air/oil reservoir temperature
