The air filter light illuminates when the new service
interval can be set for the air filter. See Section 6,
page 35, for change intervals.

Air/oil separator interval:

The air/oil separator light illuminates when the
new service interval can be set for the air/oil sepa-
rator. The factory recommends this be set at 4000
hours.

Oil filter interval:

The oil filter light illuminates when the new service
interval can be set for the oil filter. The factory rec-
ommends this be set at 1000 hours.

arator, the service interval must be
set in the controller.

MULTIPILOT MENU -- To enter the MULTIPILOT
Menu from the basic display when the compressor is
stopped, simultaneously push the up arrow and the
down arrow keys and hold for 5 seconds, until all the in-
dicator lights on the display start flashing, then select
code 03.

The settings in this menu are used when the compres-
sor is connected to the optional Multipilot control
through an RS 485 communication line.

Use the scroll key (

) to select the desired option for

programming. The numerical values can be changed
with the up arrow or the down arrow keys. The value
flashes on the display to indicate change. When the
flashing stops, the value becomes the new setting. The
following can be programmed through the MULTIPI-
LOT MENU.

Compressor identification number:

The display shows alternately the text RS 485 and
the compressor number.

When no indicator lights are on, the compressor
identification number can be changed.

The number flashes quickly as its value is being
changed.

Selecting the pressure control point:

The compressor’s pressure control point can be
changed here. The text LOCAL indicates control
by the compressor, while the text PILOT means
control by the multipilot system.

REMOTE CONTROL OPERATION -- Remote control
operation is selected by turning the selector switch on
the cabinet clockwise, FIGURE 4--2, page 15, detail
number 21.

When the remote control is enabled,
the compressor’s own start button is
not in operation. However, the com-
pressor can be stopped with the stop
button on the compressor.

In the remote control mode the compressor is operated
with a closing contact which is connected to terminal
blocks 22 and 30 of the compressor control box. The
compressor is started by closing the contact and
stopped by opening it.

MULTI--COMPRESSOR CONTROL -- If multi--com-
pressor control with the MULTIPILOT CONTROLLER
is desired, a closing contact is connected to terminals
20 and 25. When the contact is closed, the compressor
is controlled by the MULTIPILOT CONTROLLER.

In addition, a closing contact for discharge pressure
regulation is connected to terminals 21 and 27. When
the contact is closed, the compressor runs fully loaded;
when the contact is open, the compressor runs un-
loaded.
