tem pressure is, in fact, zero psig. Remove the
pressure line to the system pressure transducer.
Pressing [ENTER] will now cause the “AUTO
SENTRY–ES+” to calibrate the transducer output
to zero PSIG. Obviously, pressure measurement
errors will be encountered if ’zeroing’ is done with
pressure at the transducer. If large errors are de-
tected, the controller will demand that the trans-
ducer be checked.
3.
In the top line, “REMOVE RES PRESS” is dis-
played. The bottom line displays the current pres-
sure being sensed in the reservoir. The reservoir
pressure transducer may now be ’zeroed’ by fol-
lowing the steps outlined in 2 above.
4.
In the top line, “AIR END TYPE” is displayed. The
bottom line displays the current selection. Set as
appropriate for the compressor.
5.
“MOTOR SFA” is displayed on the top line. This
should normally be set for either the motor name-
plate service factor amps (SFA, if given) or for the
motor nameplate full load amps (FLA) times the
motor nameplate service factor (SF). It may be
set lower, if desired. Refer to other features, later
in this section, for additional details.
On units built without current monitoring, this is set
to zero to disable the current monitoring functions.
6.
This completes the configuration adjustments.
The controller will return to the main adjustments
menu.
Unit Setup Adjustments
1.
In the top line, “OIL CHANGE INTERVAL” is dis-
played. The bottom line will indicate a time interval
of 1000 to 8000 hours. After the machine has run
for the programmed setting, an advisory will be
displayed, requesting an oil change. Adjust as de-
sired and press [ENTER] to proceed.
2.
In the top line, “FILTER CHNG INTERVAL” is dis-
played. The bottom line will indicate a time interval
of 500 to 1000 hours. After the machine has run
for the programmed setting, an advisory will be
displayed, requesting an oil filter change. Adjust
as desired and press [ENTER] to proceed.
3.
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.
4.
”FAN TYPE” is displayed next on the top line. Se-
lect “AIR COOLED” for units with package–
mounted air coolers only. This will delay fan start-
up until the oil has warmed up in the package.
Select “WATER COOLED” for water cooled units
or any unit with a remote cooler. This will run the
fan whenever the compressor motor runs.
5.
In the top line, “SYSTEM VOLUME” is displayed.
The bottom line may be selected as “SMALL”,
“MEDIUM”, or “LARGE”. This tunes the response
of the modulation control loops to optimize loop
stability. It is factory set to MEDIUM. Set as fol-
lows:
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 the most ap-
propriate value, the controller will
maintain the discharge pressure with
minimized modulation changes.
6.
In the top line, “AUTO RESTART” is displayed.
The bottom line will indicate either “OFF” or “ON”.
The factory setting is “OFF”, and the controller will
display a power failure shutdown after power has
been restored.
Set this feature to ON when it is necessary to have
the compressor automatically restart after a pow-
er interruption. There will be a brief delay, then the
control resumes the mode it was in prior to the 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 used.
7.
This step is only encountered if the AUTO RE-
START function was set to ON in the previous
step. In the top line, “RESTART TIME” is dis-
played. The bottom line will indicate a time be-
tween 5 and 60 seconds. It is factory set at 10 se-
conds. This is the amount of delay introduced
before restarting after power has been restored.
Set it as desired to allow time for power to stabilize
before starting compressors.
8.
The display now reads “JOG MOTOR?” and indi-
cates the amount of time to energize the starter.
Adjust with the [+] or [–] key to the smallest value
needed to bump the motor and check rotation. 0.1
