BELARUS-1523/1523 В /1523.3 /1523В.3 Construction and Operation
153
The HLL control and adjustment sys-
tem includes an electromagnetically-
controlled regulator, position transducer
(an induction displacement transducer),
draft transducer (two draft-measuring
transducer fingers), control panel, elec-
tronic unit and cables assemblies.
The position transducer (6) is screwed
into the socket in the rear axle cover (4)
and by the eccentric (3) secured to the
turn shaft (2).
To install the BOSCH
transducer, proceed as follows:
• Raise the RHL to its top position; in so
doing, the transducer ball-point should
be opposite to the mark “А”, or slightly
displaced towards mark “B”;
• If it is not the case, loosen the screw
(1) and turn the eccentric (3) through a
required angle; then tighten the screw
(1);
• Screw in transducer (6) by hand until it
stops, then turn it off by 0.5...1.0 revo-
lutions and lock it with the lock-nut (5).
If the transducer is installed correctly,
the warning light indicating the RHL
lifting should go out when the mecha-
nism is in its top position.
IMPORTANT!
DO NOT overtighten the
nut (5) to avoid damage of the sensor
(6) made of aluminium alloy.
To install the ДП -01 transducer manu-
factured by the Izmeritel Plant, pro-
ceed as follows:
• Raise the RHL to its top position;
• Turn the setting screw (7) into the rear
axle cover (4) up to the stop while direct-
ing it into the hole in the working surface
of the eccentric (3);
• Tighten the bolt (1); turn out the setting
screw (7) from the rear axle cover;
• Screw the transducer (6) until it rests
against the eccentric and then turn it out
be one revolution and lock it by means of
the locknut (5). If the transducer is in-
stalled correctly, the warning light indicat-
ing the RHL lifting should go out when
the mechanism is in its top position.

“А” is a mark on the ascending path of the ecce n-
tric;
“B” is a mark on the descending path of the ec-
centric.
