Temperature:
indicates that the
pressure value is the “un–
load” value.
Step 4:
Press the “AUTO LEAD” button to raise the
unload setpoint. Press “AUTO LAG” to lower
the unload setpoint. See FIGURE 4–6, page
21.
Operation at excessive discharge air
pressure can cause personal injury or
damage to equipment. Do not set un-
load pressure above the maximum
stamped on the unit nameplate.
Step 5:
When the desired unload setpoint is dis-
played in the pressure readout, press the
“STOP/RESET” button. This will enter the
desired unload setpoint and advance the pro-
gramming function to the load setpoint. The
displays will now read:
Pressure: the current load setpoint (adj.
50–167 psig)
Temperature:
indicates that the
pressure value is the “load”
value.
Step 6:
Raise or lower the load setpoint in the same
manner as the unload setpoint in Step 4.
The load setpoint cannot be set within
8 PSI of the unload setpoint. See
FIGURE 4–6, page 21.
Step 7:
When the desired load setpoint is displayed
in the pressure readout, press the “STOP/
RESET” button, entering the new load set-
point and completing the programming.
Step 8:
The display now indicates:
At this time, compressor rotation may be
checked by pressing any of the three operat-
ing mode buttons. The correct rotation is
counterclockwise. The starter will be mo-
mentarily energized giving a slight rotation
that is short enough in duration to prevent re-
verse oil flow in the event that rotation is re-
versed. Press “Stop/Reset” to exit jog mode.
See Note C, below.
Step 9:
The displays will now read:
Pressure

or
If this compressor is equipped with the ex-
pansion board for the remote control option
this must be set to “yes”. The standard set-
ting is “no”. This value is toggled by pressing
either “Auto” button. Press the “Stop/Reset”
button to continue to the next step.
Step 10: The display now indicates either
or
Pressing any mode key will toggle the display
from one set of units to the other. PSI/
_
F
causes the controller to display pressures in
pounds per square inch and temperatures in
degrees Fahrenheit. bar/
_
C causes the con-
troller to display parameters in bars and de-
grees Centigrade. Press “Stop/Reset” when
the desired units are visible in the display to
continue.
Step 11: When display shows dashes (–––– ––––):
(The Following steps may be skipped by
waiting until the display resumes its normal
numbers.)
a)
Press “Stop–Reset” – the pressure display
now shows the current “zero” pressure for
the final discharge transducer in the left win-
dow, and “P1” in the right window.
b)
Press “Stop–Reset” again – this will zero the
circuit board on the final discharge pressure
transducer and move the display to the next
step. The left window will read the current
“zero” pressure for the oil reservoir transduc-
er and the right window will now read “P2.”
c)
Press “Stop–Reset” again – this will zero the
circuit board on the oil reservoir pressure
transducer and move display program back
to the normal setup mode. The display
