Use
Method of operation
ILAS®-E+ is used for electrically controlled raising and lowering of one or more lift-axles with conventional air suspension systems� On EB+ systems, a load-dependent output signal is used to provide electrical actuation of the ILAS®-E+� In the case of standard installations (without EB+), ILAS®-E+ can also be controlled by means of a separate special pressure switch with two adjustable pressure switching points (load dependent)�

Installation Guide
Fitting guidelines
Mechanical part 3.
They are fastened after installation drawing with an M8 srew and the fixing pin� The pin is used to fix / twist on the console� The installation site should be chosen such that ILAS®-E+ is shielded from stone impacts, is not exposed to splashing or flood waters and is protected from high pressure cleaning� Approp-riate safeguards against unauthorised activation should be provided by the vehicle manufacturer� Pneumatic connection can be made according to a installation diagram, for example�
Pneumatic part 8.
Plastic tubing that complies with DIN 74 324 - 8x1 should be used for pneumatic lines for equipment with plug connections� When fitting the pneumatic lines, care should be taken to cut the tubing to the required length square and without leaving burrs by using a suitable tool�Observe manufacturer’s instructions for pneumatic push in / glands�During painting, all open plug-in connections, the connection to the atmosphere and the air exhaust must be protected from the ingress of paint by using appropriate shielding� This shielding must be removed again after painting�
Electrical part 4.
Bayonet connection complying with DIN 72585 A1-2�1-SN/K1� When making the bayonet connection, care should be taken that the gland nut is correctly seated and locks properly into place when turned clockwise, so as to ensure optimum sealing� The cable with the order no� 814 012 ��� can be used for Haldex EB+�For connecting to EB+, see installation note 006 300 018�Haldex Brake Products GmbH accepts no liability for any other method of actuation�Solenoid only to be turned in rotating direktion max� 90°

MaintenanceTo lower the lift axle, for example, during servicing, the voltage must be interrupted� Alternatively, a shut-off valve with an air exhaust (e�g� 334 077 001) can be installed upstream of Connection 1, which, when operated, likewise switches off the lifting device (so that the axle lowers)�If defects are discovered, whether during examination of the vehicle, when travelling or in the course of commissioning, the device must be replaced�When working with high pressure cleaners the safety regulations of the manufacturer�
Check › Check functionality and leak tightness.
› Function: When the voltage is on: Axle is lifted When the voltage is off: Axle is lowered
› Correct installation position, see installation drawing.
