Adjusting The Length; Mounting The Barrier Pole (90° Articulated); Mounting The Articulated-Guide - Chamberlain LiftMaster BARS1 Mode D'emploi

7.7

Adjusting the length

The unmounted barrier pole is longer than actual barrier operation width.
This width is always 270mm shorter.
If a barrier pole support is used then operation width is decreased by about 100mm.
The barrier pole cannot be shortened on the side of the drive but on the opposite end.
The end cap can be removed and then the length of the pole can be adjusted.
7.8 Mounting the barrier pole (90° articulated)
Mounting these barrier poles at the axle is the same as with the straight version. See Mounting the
barrier pole (straight).
Before fitting the barrier pole the articulated-guide must be installed. Furthermore see Mounting the
articulated-guide and Fixation and setting of push rod for articulated barriers.
Note: The full length (max. 3200mm) articulated pole may only be used in combination with
barriers with a run time of 3 to 6 seconds. Barriers with run times of 1 second may only be used in
combination with articulated poles of max. 2500mm length.

7.8.1 Mounting the articulated-guide

The articulated-guide is installed behind the pivot point of the
barrier pole. It is essential that the necessary drillings are
executed accurately. There is near enough zero tolerance in this
case and inaccurate works cannot be compensated. If the articu-
lated-guide is wrongly positioned the pole cannot be set and
hangs downwards, stands upwards resp. a final position is not
adjustable.
Note: This work should not be done on site, but should be
prepared in the workshop.
Adhere to the following course of action:
• Position barrier without pole on a solid surface (workshop) and
remove hood (see Removing the hood)
• Relax barrier spring and remove (see Setting of springs)
• Release barrier by means of key and turn in open direction
(see Release)
• Take accurate measurements of drillings for articulated-guide,
indicate and prebore with no more than 4-5mm. After that bore
through with 8.5mm
• The measurement from the upper plate to the upper drillings of
the fitting is crucial and equals 45mm. The drillings located
below are set 50mm lower
• The measurement from the centre of the rotation axle of the
barrier to the first of the two drillings is 83mm (horizontally).
The drillings behind are 40mm further away.
• Between articulated-guide and casing there is another plate.
This plate is important because the casing cannot be mounted or
removed otherwise
• Due to engineering the threads of the articulated-guide are first
cut and then varnished. Please check condition of threads. If
need be spray with oil to ensure that the screws can be fitted
more easily
• It is advisable to work with a long extension in order to fit and
tighten the screws
• The articulated-guide must have a firm fit and not have any
clearance
• Fit casing and check
• Then refit barrier spring and go through steps above in reverse
order. But do not tension spring yet, merely put nut back on
