Introduction
338 051/054...
1
The manually Raise/Lower valve with dead man's function, is
used for raising and lowering the deck height of commercial
vehicles and trailers. When electrically connected to the ABS via
a solenoid valve, the system provides automatic reset to ride.
Operation
Position "drive" 11
When the lever is in the central position it may be pulled out and
locked to prevent unintentional operation. Connections 11 are
linked with 21 and 22 providing a direct connection between the
height control valve and the air bellows. See 15
Position "Stop" 11
When the lever is in the central position and pushed in, connections 11 and 12 are isolated from connections 21 and 22.
338 052/053...
Position "raising" 11
When the lever is operated from the 'stop' position in an anticlockwise direction approx. 45° connections 21, 22 are linked with
connection 1 and the air bellows are inflated.
On relaise, the lever automatically returns to the central 'stop'
position and isolates connections 21, 22 from connection 1
preventing further bellow inflation.
(Note that the deadman function' is not available on
338 053/055...).
2
Reset from "Stop" position to "Drive"position
When the lever is in the central position it may locked by pulling
it out so that unintentional operation is prevented.

21
Position "lowering" 11
When the levers is operated approx 45° in a clockwise direction
form the "Stop" position, connections 21, 22 are linked with
connections 3 and the air bellows are deflated.
On release the lever automatically returns to the central position
and isolates connections 21, 22 from connection 3 preventing
further deflation of the bellows.
(Note that the deadman function' is not available on
338 053/055...).

NOTE : DANGER !
No-one should be standing in the danger area when raising and lowering
procedures are being carried out.
Only 338 051/054...: if the solenoid valve on the underside of the
unit 5
(UB= 24 VDC +2,5.- 3,5) of the Haldex-ABS 10 is
controlled with a pulse (when vehicle speed>15km/h) then reset
of the lever from the 'stop' position to the 'drive' position is
automatic.

The assembly is mounted by least 2xM8 bolts 5,6 via
holes provided on the housing**. The installation location should be selected, clear of direct spray or splash
and with some protection from high pressure cleaners.
The operating lever should be easly accessible. 2 Care
should be taken to ensure the lever does not protrude
over the edge of the vehicle when pulled out. Corresponding protection against unintentional operation
should be provided by the vehicle manufactures. Pneumatic connection should be in accordance with assembly diagrams. 13,14
The exhaust port"3" 5,6 should be protected against
contaminantion by fitting a silencer 059 0460 09, or by
means of an elbow and a short length of tube of
minimum inside diameter 9mm (e.g. Tube 12x1.5).

Maintenance
COLAS is effectively maintenance free and only needs to be
changed if the functionality is compromised or leakage is
detected during normal servicing.
NOTE:With high pressure cleaners a safe distance of a least
50 cm from the COLAS should be observed.
Testing
-check function and leak-tightness of equiqment
-correct assembly position 5,6
-instruction Label in position 11
For 338 051/054...: A throttle 12 is provided with
COLAS which is fitted in the "T" piece and is required
in order to bypass the height limiting device.
As t-piece you can use the components from fig. 12 If
no height restriction is used, the throttle is not required.
Plastic tubing in accordance with DIN 74324-O 8x1or
10X1 should be used for pneumatic lines. When
assembling pneumatic lines care should be taken to
ensure that the tubes are cut sqare and free from burrs.
Before inserting the tubes in the push in connections,
insert must be fitted in the tube ends in accordance
with Haldex number 032 0490 09 (8mm) or 032 0491
09 (10 mm).
Tube penetration should be at least 23mm deep in the
push in fittings* 3
So that the permissible height is not exceeded when
raising the deck height, it is advisable to use the
equiqment in conjunction with a height restriction devise
(e.g. Haldex height control valve with height limitaiton)
13,14 . All open plug and socket connections and
exhausts should be protected against contamination
during painting. After painting, the protective devices
should be removed again. Reference plate 028 0410
09 11 shoud be fixed in the vicinity of the COLAS
valve.
338 051/054...: An electrical connection to the solenoid valve only permissible 10 by means of a Haldex ABS
ECU which delivers a signal 'reset-to-ride height'. Haldex
does not accept any liability for other types of control**.
*After removing the protective cap, the plastictube can
be removed again by pressing down the clamping ring
with the flat face of an open ended spanner.
(e.g.when changing).
** For other controls please note: Fixing with 4 bolts.

Operating instructions
On claims we have seen, that the handle was broken, due to wrong operation. Position "RAISE" or "LOWER"
is only possible from position "STOP". In position"DRIVE" the handle is fixed. If You try to turn the handle from
the position "DRIVE" with more than 35 Nm you will break the unit. To get position"STOP" you have to push
the handle from position "DRIVE" 15
