2940 AIR ADJUST
CAB CONTROLLER OPERATION
5. Main Screen System Operation
5.1. Supply +12Vdc to system. Before power button is pressed system will be in stand by mode, with
red illuminated buttons.
5.2. Press and hold “Power” button, this will power up the switch panel.
5.3.
The Air System needs to be enabled by pressing the ENTER button. This will allow the
compressor to run. The compressor is controlled with a window switch that closes if it is below its
threshold PSI, if pressure exceeds the threshold (approx 100 PSI) it will shut off until it falls below
the bottom threshold of the window (approx 80 PSI) at that point it will close and attempt to run the
compressor again. If the compressor runs for 15 minutes continuously it will shut off and the
associated warning screen will be displayed; pressing ENTER will clear the warning screen and
shut the air system off. Pressing ENTER again will restart the air system (the compressor will also
restart if it needs to).
5.4. Pressure Adjustment: Along the bottom of screen 1 will be up to (6) pressures. These
pressures are adjusted by using the rotary encoders. Adjusting these will put the system into edit
mode and the values shown will be command values. After 7.5 seconds the system will exit the
edit mode and the values will return to live values.
5.4. A Encoder 1: Adjusting this encoder will increment the RU (up pressure) command value up or
down by 1 PSI/step.
5.4. B Encoder 2: Adjusting this encoder will increment the RD (down pressure) command value up or
down by 1 PSI/step.
5.4. C Encoder 3: This encoder is used to adjust WT, A1, A2, and A3. You must press the encoder to
enter the edit mode; a cursor will appear on the screen below the value you can adjust. It will start
at WT and move right every time you press the encoder (if you stay in edit mode). Once the cursor
is on the value you would like to adjust rotate the encoder and it will increment the command value
up or down by 1PSI/step.
5.4. D
Saving Presets: All PRESETS will default to 0 upon initial start up. Adjust one or more of the
pressures to the desired value. Press any one of the P (1-5) buttons along the top of the switch
panel for 2 seconds. This will save the values to that PRESET.
If you make an adjustment to a preset it will say PRESET x MANUAL at the top of the
screen. Once you save the preset it will return to PRESET x.
5.5.
RMU/RMD Dump Valve Operation: When dump valve button I is pressed the RM Down Dump
will release air. When dump valve button I is pressed again RM Up Dump Output will release air for
(x) seconds (this time delay is set in the DUMP VALVE DELAY screen). After the timer elapses
both dump valves will be closed and the system will return to whatever pressure is being
commanded by the PQE’s.
