TIREMAAX
®
EC HAND-HELD PROGRAMMING DEVICE OPERATION
6
L867A
When connected as described, the hand-held
programming device will automatically enter the tire
pressure setting mode. The tire pressure setting mode
displays the present target pressure setting in the
upper right corner of the display (figure 5).
If you don’t see this screen on the hand-held
programming device, unplug everything and
reconnect the hand-held programming device in the
order previously described. Make sure the last
connection made is the four-pin trailer power cable to
the hand-held programming device.
The hand-held programming device has three
operational modes:
• target pressure setting mode
• diagnostic test mode
• fault code history mode
The target pressure setting mode is always the first
mode entered when the hand-held programming
device is powered. To navigate to the other
operational modes, use the TEST button, BACK
FAULTS or FWD FAULTS arrows, and the +PSI or -PSI
arrows as shown in figure 6.
TARGET PRESSURE SETTING
The target pressure setting mode is used to program
a different tire pressure setting into the TIREMAAX
®
EC
controller.
NOTE:
For TIREMAAX EC to function properly, the
trailer air tank pressure must be higher than
the target tire pressure. TIREMAAX EC is only
capable of allowing available air tank pressure
to reach the tires. It is not capable of supplying
pressure above the available air tank pressure.
When the target pressure setting mode is entered, the
display shows the present target pressure setting
(figure 5). This screen provides a visual indication
that you are in the target pressure setting mode.
1.
To select a different pressure setting:
Press the +PSI arrow on the direction pad to
increase the target pressure setting or the -PSI
arrow on the direction pad to decrease the target
pressure setting (figure 7).
Each time the +PSI or -PSI arrow is pressed, the
target pressure setting is raised or lowered by
five psi and the display shows the newly
selected pressure setting (figure 7). Possible
target pressure settings are 70, 75, 80, 85, 90,
95, 100, 105, 110, 115, 120, 125 and 130.
