(1.8 kg) Power/voltage: 24 Nominal (16-32) VDC 3.4 watt Enclosure classification: IP64 per DIN 40050 Operation: Energize the level solenoid to block communication of the height control valve. Then energize the exhaust solenoid to initiate kneel. De-energize the exhaust solenoid and energize the fill solenoid to allow bus to quickly rise up. Then de-energize the fill solenoid and level solenoid to allow communication of the height control valve. Note: HCV solenoid must be energized and remain on when kneeling the bus/coach.
