Introduction
Operating the WirelessAIR Control System
GENERAL DESCRIPTION
The WDC has nine push buttons that are used to activate the remote and control all system
features. The manifold is a board-on-coil design incorporating onboard pressure sensors. The
system communicates using 2.4GHz radio modules, with measures taken to ensure that the
WDC and manifold only accept information from the unit to which they have been joined.
Due to the three valve design of the manifold, the system is not capable of simultaneous ll
and dump operations on the two air bag circuits. A new setting sent to the manifold requiring
both a ll and dump will be accomplished by doing the dump rst followed by the ll.
If the battery icon on the WDC display is on, the batteries are nearing exhaustion and should
be replaced promptly (g. 1).
The purpose of this publication is to assist with the operation of the WirelessAIR system
consisting of two main components: The wireless digital controller (72001), hereafter referred
to as the WDC; and the wireless manifold (72003).
It is important to read and understand the entire user guide before beginning to operate
your WirelessAIR system.

USER INTERFACE SWITCHES
The WDC has nine switches. The ve switches that make up the navigation switch are
referred as TOP, RIGHT, LEFT, BOTTOM, and MIDDLE. The four switches on the lower
edge of the WDC are referred to as P1, P2, DOWN, UP (going from left to right) (g. 2).

WDC OPERATING MODES
In Sleep Mode, the WDC enters a very low-power state. The radio and backlights are shut
off, and the display shows the Air Lift logo, the compressor bar outline, and “- -“ in the left
and right digits. Before entering Sleep Mode, the WDC checks the battery condition and
displays the battery icon if the battery voltage is low. The display is not updated while in
Sleep Mode.
In Option Mode, four options are shown,
l Jn -r : Join rear axle manifold. See installation manual, page 11.
l Jn -F : Join front axle manifold. See installation manual, page 11.
l En d?: Exit option mode.
l dI SP: Alternate between units, PSI and BAR. See installation manual, page 11.
Use TOP and BOTTOM to scroll through the options. The displayed option is selected by
pressing and releasing MIDDLE. Use LEFT and RIGHT when changing units in “dISP.”
In Operating Mode, the WDC indicates the currently selected manifold by illuminating the
TIRE ARROWS corresponding to the front or rear axle (g. 5). If two manifolds are joined,
press MIDDLE to toggle between the front and rear manifold.
When the WDC has been inactive for a period of time, it automatically enters Sleep Mode
in order to conserve battery power (g. 3).
g. 3
Pressing and releasing any switch other than MIDDLE will cause the WDC to wake up
and resume operation. The button pressed to wake up the WDC is not acted on until it is
pressed again.
If the WDC has not already been joined to one or more manifolds, it will automatically enter
Option Mode on wake up, where it can be joined to an manifold (g. 4).
g. 4
Once the WDC has been joined to at least one manifold, it will enter Operating Mode on wake-
up.

The TIRE ARROWS indicate which pressure settings (left, right or both) will be adjusted.
The numeric displays initially indicate the last setting sent to the currently selected manifold.
If there is no activity for 10 seconds, the WDC will return to Sleep Mode.
The WDC responds to the switches as follows:
TOP Press and release to increase the selected pressure settings by 1 PSI.
Press and hold to rapidly increase the selected settings. The maximum
setting is 100 PSI or 69 BAR.
RIGHT Press and release to sequence the TIRE ARROW indicators through both
right and left. Only the pressure settings (left, right) having a TIRE ARROW
visible will be changed by thte TOP/BOTTOM switches
LEFT Press and release to sequence the TIRE ARROW indicators through both
left and right. Only the pressure settings (left, right) having a TIRE ARROW
visible will be changed by the TOP/BOTTOM switches.
BOTTOM Press and release to decrease the selected pressure settings by 1 PSI.
Press and hold to rapidly decrease the selected settings. The minimum
setting is 5 PSI.
MIDDLE Quickly press and release to send the pressure setting to the selected
manifold (front or rear axle). See “Sending New Settings”.
Press and hold to switch between the front and rear axles (will only work
if a second manifold is linked).
P1/P2 Quickly press and release to send the preset #1 pressure setting to the
selected manifold (front or rear axle). Individual presets are stored for
each axle. The default value for preset #1 is 25 PSI. The default value
for preset #2 is 75 PSI.
The WDC is designed to be able to retain 2 presets for the front manifold
and 2 presets for the rear manifold. To store the current pressure settings
as the new preset #1, press and hold P1 until the display shows “Str”
(g. 6).
Release P1 and the display will show “Str1” to indicate the settings have
been stored to preset #1 (g. 7).
To store the current pressure settings as the new preset #2, press and
hold P2 until the display shows “Str” (g. 6). Release P2 and the display
will show “Str2” to indicate the settings have been stored to preset #2
(g. 8). Both preset settings are retained even when the WDC batteries
are removed.

To store the current pressure settings as the new preset #2, press and
hold P2 until the display shows “Str” (g. 6). Release P2 and the display
will show “Str2” to indicate the settings have been stored to preset #2
(g. 8). Both preset settings are retained even when the WDC batteries
are removed.
DOWN Pressing DOWN will decrease the left and right pressure settings to 5 PSI,
and then send the new setting to the currently selected manifold. This
command is sent instantly, you do not need to push the middle button to
send the setting.
UP Pressing UP will increase the left and right pressure settings by 10 PSI,
and then send the new setting to the currently selected manifold. See
“Sending New Settings”. This command is sent instantly, you do not need
to push the middle button to send the setting.
SENDING NEW SETTINGS
When new setting are sent from the WDC to a manifold, the WDC will display “FAIL” if it
does not receive any response from the manifold (g. 9).
g. 9
If the manifold acknowledges the new settings, the WDC will then wait for the manifold to
get to the new setpoint pressures. While it is waiting, the WDC will update the display at
one second intervals with the actual air bag pressures, and show the compressor icon (g.
10) or dump arrow (g. 11) to indicate the operation in progress.
The WDC will continue to update the settings until:
1. The manifold achieves the new settings, at which point the WDC returns to displaying
the current settings.

2. The WDC is unable to get any status information from the manifold for 10 seconds, in
which case the WDC will return to Sleep Mode.
3. Three minutes have passed since the settings were sent, in which case the WDC will
return to Sleep Mode.
MANIFOLD OPERATION:
The current air bag pressure settings will be automatically maintained by the system subject
to the following constraints:
1. The maximum pressure is 100 PSI (see your air bag’s installation manual for individual
maximum ination pressure).
2. The minimum pressure is 5 PSI.
3. In general, the system will not dump air from an air bag circuit unless commanded by the
user. The only exception is if the average air bag pressure exceeds 110 PSI, in which
case it will be bled down to below 110 PSI.
4. The system will limit continuous compressor operation to 3 minutes. After 3 minutes,
the system will lock out all compressor operations until power is cycled, or a 7 minute
cooling period takes place (g. 12).
