Compressor/Pump: Description and Operation

Description

The compressor operates in all events except the system air filling and two solenoid valves (referred to as reverse valve, on-off control, and normal open) are embedded.
Air dryer is maintenance free (permanent use).The relief valve opens upon the pressure of 20±3bar.The compressor relay is monitored by control module in order to detect any failure in relay. If the compressor relay is failed (short to battery, short to ground or open circuit), the lifting is prohibited but down leveling is only available. However, the down leveling is done not by compressor but ambient valve.
