Ilas -E - BPW ECO Tronic EBS Operating And Installation Instructions

®
5.2.5 ILAS -E
Application
®
„ILAS -E" is used for electrically controlled lifting and lowering
of one or several lift - axles with conventional air suspension
systems.
With electronically controlled air brake systems, e.g. EBS,
ILAS- E are controlled by the load depended output signal.
Principle of operation
Electrically actuated lift axle control device for lifting and
lowering of lift axle(s).
With electric power on: Axle is up
With electric power off: Axle is down
Traction control: By using a traction control device you have to
follow the regulations for lift devices (97/29/EG).
Installation Guidelines
Mechanical Part:
The ILAS-E should be mounted using the holes which are
provided. It should not be located in an area where there is
excessive water spray / splash and should be protected from
high pressure washing equipment. Additional protection should
be provided by the vehicle manufacturer against unintentional
activation.
Pneumatical Part:
A nylon pipe in accordance with DIN 74 324 - 8x1 should be
used for the versions with push-in fi ttings. When assembling
the air pipes, care should be taken to ensure that the pipes
are cut square, to the required length and are free from burrs.
Inspection
Check function of unit and security.
Function:
With electric power on: Axle is up
With electric power off: Axle is down
To lower the lifting axle, e.g. for servicing work (HU, SP), the
power supply must be interrupted. Alternatively, the lifting device
can also likewise be switched off during operating through
pre-fi xing of a stop cock with venting before connection 1 (axle
lowers itself).
Porous rubber parts must be replaced.
When painting is being undertaken, all open connections, the
atmospheres connection and the breather must be protected
against paint penetrating inside by using suitable means. The
protective measures must be removed again once the painting
work has been completed.
A safety distance of at least 50 cm should be kept when working
with high pressure cleaners.
