of 8000 hours. 8000 hours is the maximum set-
ting, and is the proper change interval for AEON
9000 SP synthetic oil. See FIGURE 5–3, Section
5, page 37 for proper setting for AEON lubricants.
16. In the top line, HI TEMP LIMIT is displayed. The
bottom line will indicate 225 degrees F. This is the
maximum (and proper) setting for compressor op-
eration. It may be temporarily lowered to verify the
function of the temperature shutdown system.
17. In the top line, FAN TYPE is displayed. The bot-
tom line will indicate either AIR COOLED or WA-
TER COOLED. Selecting AIR COOLED places
the fan under thermostatic control while WATER
COOLED operation runs the fan whenever the
main motor runs.
18. In the top line, AUTO RESTART is displayed. The
bottom line will indicate either OFF or ON. Set this
feature to ON when it is necessary to have the
compressor automatically restart after a power in-
terruption. This feature shall only be enabled
when the owner determines that it is safe to do so.
It is recommended that compressor access be
limited to only trained service personnel when this
feature is enabled and appropriate warnings are
posted.
19. This step is only encountered if the AUTO RE-
START function was set to ON in step 18. In the
top line, RESTART TIME is displayed. The bottom
line will indicate a time between 5 and 60 seconds.
It is factory set at 10 seconds. This is the amount
of delay introduced before restarting after power
has been restored to ensure a stable supply is
available and staggered starting is accomplished.
20. In the top line, AIR END TYPE is displayed. The
bottom line will indicate either TURNVALVE or
NON TURNVALVE. It is to be set as is appropriate
for the compressor.
21. In the top line, SYSTEM VOLUME is displayed.
The bottom line may be selected as SMALL, ME-
DIUM, or LARGE. This tunes the response of the
modulation control loops to optimize loop stability.
It is factory set to MEDIUM. Set as follows:
SMALL if estimated volume is less than .25 gallon
per CFM.
MEDIUM if estimated volume is between .25 and
1.0 gallon per CFM.
LARGE if estimated volume is greater than 1.0
gallon per CFM.
The setting of this parameter is not
critical. When set to its most ap-
propriate value, the controller will
maintain the discharge at the closest
possible value. If not set correctly,
pressure will vary from the desired
setpoint to a somewhat greater de-
gree but the compressor and its com-
ponents will not be adversely af-
fected.
22. In the top line, REMOVE SYS PRESS is dis-
played. The bottom line displays the current pres-
sure being sensed at the package discharge. At
this point steps must be taken to ensure that sys-
tem pressure is, in fact, zero. If necessary, remove
the line to the system pressure transducer. Press-
ing ENTER will now cause the ”AUTO SENTRY–
ES” to calibrate the transducer output to zero PSI.
Obviously, pressure measurement errors will be
encountered if ’zeroing’ is done with pressure at
the transducer.
23. In the top line, REMOVE RES PRESS is dis-
played. The bottom line displays the current pres-
sure being sensed in the air/oil reservoir. The res-
ervoir pressure transducer may now be ’zeroed’
by following the steps outlined in 22 above.
24. The display now reads PRESS CNST RUN TO
JOG MOTOR. Pressing the ”CONSTANT RUN”
key will briefly energize the starters, causing com-
pressor to rotate 1/4 to 1–1/2 revolutions to allow
a rotation check.
This completes the programming and setup proce-
dures for the ”AUTO SENTRY–ES” controller. Press
the ”STOP–RESET” key to return the compressor to
the ’READY’ mode.
