Note: Configuration adjustments are normally re-
quired only at the time of assembly or after parts have
been replaced. Unit setup adjustments are normally
required only at the time of unit installation. To prevent
accidental access, these will not be available if the
“SET” switch is in the position closest to the corner.
The “SET” switch is located on the bottom of the con-
troller chassis, on the side behind the program keypad
area. If the switch is towards the center of the control-
ler, all five adjustment sections are accessible.
Operation Adjustments
1.
In the top line, “DISPLAY UNITS” is indicated.
The bottom line will indicate “ENGLISH” (PSIG,
Fahrenheit) or “METRIC” (Bars, Celsius) units of
measurement. Select the desired display units
and press [ENTER] to proceed.
2.
In the top line, “START TIMER” is displayed. The
bottom line will indicate a time between 3 and 10
seconds. This is the time that the controller
spends in the unloaded ‘start’ mode. This also
controls the operation of package–mounted wye–
delta starters, if so equipped. Set this adjustment
for the amount of time needed for the motor to
reach its highest speed while starting. This is typi-
cally 3 seconds for full–voltage starters, 7–9 se-
conds for wye–delta starters.
If a remote–mounted, reduced voltage starter is
used, set this adjustment 1–2 seconds longer than
the starter’s internal timer.
3.
In the top line, “SET PRESSURE” is displayed.
The bottom line will indicate a pressure value. It
is to be set at the nameplate rating of the compres-
sor for normal operation. Under NO circum-
stances, is this adjustment to be set in excess of
the compressor nameplate pressure. It may be
set lower, if desired, to reduce pressure and power
consumption.
4.
In the top line, “RESET PRESSURE” is displayed.
The bottom line will indicate a pressure value.
This setting determines the point at which ma-
chine startup occurs in AUTO and SEQUENCE
modes and when the compressor will load up from
the blown down condition. Note that RESET
PRESSURE can be set up to 5 PSI below SET
PRESSURE. Set this lower to reduce compres-
sor cycling. All sequenced machines must have
the same SET and RESET PRESSURE set-
points.
5.
In the top line, “BLOWDOWN TIME” is displayed.
The bottom line will indicate a time between 5 and
20 minutes. It is factory set at 10 minutes. This
is the minimum time interval between blowdowns.
A longer blowdown time minimizes wasteful
dumping of compressed air when loading is likely
to occur in a short time.
6.
In the top line, “AUTO TIME” is displayed. The
bottom line will indicate a time between 5 and 20
minutes. It too, is factory set at 10 minutes. Its
function is to prevent too frequent motor starting,
and to allow the motor a ’cool–down’ period before
stopping.
7.
“IV CONTROL MODE” is displayed on the top
line. Select “MODULATING” for standard opera-
tion. “LOAD–UNLOAD” may be selected for sys-
tems with large storage and wide pressure differ-
ential.
8.
In the top line, “REMOTE STOP” is displayed.
The bottom line indicates either “TIMED” or “IM-
MEDIATE”. Refer to the description of “Remote
On / Off” later in this section for additional details.
Select the desired response to the remote input
and press [ENTER] to proceed.
9.
This completes the operational adjustments. The
controller will return to the main adjustments
menu.
Maintenance Adjustments
1.
If any service advisories are in effect (yellow AD-
VISORY indicator is on), they will be displayed on
the top line. The bottom line indicates “LEAVE
ADVISORY” (do not reset) or “CLEAR ADVISO-
RY” (turn it off). Select the desired action and
press [ENTER] to proceed.
Note that both the “CHANGE OIL” and “CHANGE
OIL FILTER” advisories are based on operating
time. These timers are not automatically reset on
the ES+ when the advisory is turned off, and the
advisory will come back on shortly after the unit
starts running. If the oil or filter has been changed,
clear the advisory as noted above, then proceed
to the following steps to reset the appropriate tim-
er back to its full value.
2.
The top line displays “NEXT OIL CHANGE” and
the estimated hours remaining are displayed on
the bottom line. The actual time will be affected by
operating conditions which affect oil life. Press the
[+] or [–] keys to switch to the oil change interval
(see UNIT SETUP) if service was performed ear-
ly. Press again to change back to remaining time.
When the desired value is shown, press [ENTER]
to save and proceed to the next step.
If the advisory message is on, it must be cleared
as noted in step 1.
3.
The top line displays “NEXT OIL FILTER” and the
hours remaining are displayed on the bottom line.
Press the [+] or [–] keys to switch to the oil filter in-
