Scanning the chain length with sensor, "small" drive head
You can see the
elongation of the chain
through the slot (A)
in the protective case.
The lever (B) of the chain
tensioner moves from
the top (new/shortened
chain) downwards
(elongated chain) as the
chain length increases.
If the lever is no longer
visible in the slot, the chain
must be shortened.
Alternatively, install a sensor
(E, 3 842 551 761 / ø8 mm,
max. length incl. bending
radius of the cable: 45 mm)
in the attachment tab.
Switching distance
1.5+0.5mm
The vane (C) damps the
sensor when the maximum
permissible chain length
is reached.
Please note:
• Be sure to comply with
the switching distance;
otherwise, the sensor will
be mechanically destroyed
• For control, lead the cable
out through the cutout in
the protective case.
