• Check for Compressor failure. • Check for Pressure Sensor failure. Pressure Sensor is not reading. • Verify wiring to Pressure Sensor. • Check Pressure Sensor for failure. - Page 14 - SwitchSpeed™ Controller Manual V1.3 © 2009 AccuAir Control Systems, L.L.C. - Page 15 If the vehicle system voltage drops below 10.5 volts during operation, the SwitchSpeed™ will automatically turn the compressor(s) OFF and show the trouble indication below. The SwitchSpeed™ will go back to normal operation once the vehicle system voltage reaches 12.5 volts or the ignition is cycled.
