2. Adjusting the tire pressure
The CTISr only works with the hoses connected and the ignition
switched on.
Once the compressed air system provides enough pressure, the 1l air
tank is filled and supplies the operating pressure for the control
panel.
The rotary switch is used to select between four different preset tire
pressures:
Highway (HWY)
Off-road (OFR)
Sand | Mud (S/M)
Emergency (EMC)
Turn the ON|OFF switch to “ON”. This opens the tire valves to
regulate the selected pressure via the main control unit.
The pressure indicated on the actual pressure gauge moves towards
the preselected pressure. Due to the flow process, particularly when
deflating the tire, the indicated (dynamic) pressure is not the exact
same as the (static) pressure in the tires. The correct pressure will
only be indicated towards the end of adjustment.
When the required target pressure is reached, turn the ON|OFF
switch back to “OFF” to close the tire valves and depressurise the
rotary unions.
If the vehicle has previously been used to navigate mud flats, it is
advisable to set the control pressure initially below the current tire
pressure to activate the proportional valve so it lets pressure o via
the potentially soiled silencer and cleans the filter element.
