Pressure Switch Adjustment - Acer Wood Runner Manual

8.4 PRESSURE SWITCH ADJUSTMENT

The purpose of the pressure switch is to provide a warning and prevent operation when the air pressure to
the system is below the required pressure. Low pressure will not allow the safety brake to release and will
impair other functions. The pressure switch is provided with an LED light that illuminates if the pressure is
high enough for system operation and an output to the Wood Runner's computer. Setting the pressure
switch is a simple push button operation which is detailed below.
1. Enable the system to allow air to reach the pressure switch. A disabled or E-stopped system will not
allow the adjustment
2. Turn the main regulator control knob counter-clockwise to lower the system pressure to 75 PSI.
3. Using a pen or pencil push and hold the set button on the pressure sensor until it flashes
continuously.
4. Let off the button and reset the main regulator to 90 PSI by turning the knob clock-wise to increase
the pressure to 90 PSI.
