The balancing machine TROLL 3100/3105 is equipped with a speach synthetiser, emitting
confirmations of each operation performed and suggesting procedures for whel balancing.
Indications quantity and position unbalance take reading on monitor measurement.
Programme „hiden weight” allows on the partition and the spacing of balancing slugs
on invisible spoken of alloy rim. Balancer is equiped an automatic stop at the top which
is blocking of wheel for both point of unbalancing. The brake release is seting after a
little displacement (ca. 3 grades) of wheel from shown unbalancing points or after press
the button on the keyboard which indicate a disapperation of arrows.
2 . INSTALLATION
TROLL - 3100 / 3105 balancing machine should be installed in a closed, dry room, heated during
auttumn / winter season. The machine should be installed on a hard and levelled floor. The balancing
machine should be installed on three rubber pads, suppiled with the machine (item 28, fig. 2)
which should be inserted under the three flat feet welded to the machine base.

8. OPERATING BALANCING MACHINE COMPUTER
8.1. Switch balancing machine computer
Switch machine master switch on, as well as monitor power supply switch. Balancing machine
will emit announcement [SYSTEM TEST] and them [ SYSTEM OPERATIVE]. Atest pattern shall
appear on monitor screen and then an advertisingimage. After depressing any key of the
keyboard (fig 1) the computer will be set in [UNBALANCE MEASUREMENT] subroutine and the
image shown in (fig 6) will appear on the monitor screen.
NOTE:
If during the inspection test, key (item.14 fig.1),is depressed,system test will be interrupted
and advertising image display procedure will be interrupted. The computrer will be immediately
set in [UNBALANCE MEASUREMENT] subroutine.
8.2. Select measurement procedure
After depressing the key computer is set in SELECT PROCEDURE programme and image,

shown in Fig 5 will appear on the screen.
Entry into respective subroutine is effected by depressing keys.Input to respective subroutine is
effected by guiding the cursor to an appropriate position (box with appropriate subroutine) and
depressing the key . Cursor guiding - by depressing keys .
Output from respective subroutine - by depressing the key .
SELECT PROCEDURE will appear on the screen, shown in Fig. 5
8.3. Unbalance measurement
Cursor guiding by depressing keys an position UNBALABCE MEASUREMENT
(Fig.5) and push button . The computer will set in the subprogramme UNBALANCE
MEASUREMENT, the monitor will show the screen as per figure .6.
After this subprogramme has been initiated , the cursor will always point item 5 ( Q - cut - off
threshold).

Guide cursor to position 10 (fig.6) with keys 17, 18, 19, 20 (fig.1). It is choice between automatic
and manual start.
- AUTOMATIC START - by means of keys or setting iconrepresenting pictogram
D))))) . Balancing machine comuter will be then programmed for automatic start. In this case,
parameters of the wheel, mounted in the chuck, will be entered in machine memory during
wheel guard closure and after closing the guard the machine will start automatically, measure
unbalance value, stop the wheel and display measurement results.
- MANUAL START- by means of keys or setting in position 10. Balancing machine
computer will br then programmed for manual start. In this case, parameters of the wheel to be
balanced are entered to machine memeory, as described in items 8.3.1. - 8.3.3.
Above is concerning balancer TROLL 3105 Automatic start in balancer TROLL 3100 is setting
other way. The change of mode starting will be realized by simultaneous pressing the button
and button . If will show inscription AUT in position „10” (fig 6). The automatic
starting will be connected after a closing of guard. If the inscription AUT isn”t shown. It means that
machine is programming in manual start. The engine is connecting after pressing the button
.

Wheel distance setting should be dtermined as follows:
a) after the positioner has been moved to the rim edge and than back to the start position a
number will be shown which is in a proportion to the positioner move (see fig. 7a)
NOTE:
The positioner must not be in the protruded position during the balancing machine switch - on
and the computer reset. Otherwise the distance measurements will be false as the computer
reads the positioner is position during switch - on as the zero position.
b) in case the distance should be entered without using the positioner the following should be
done:
(look fig.7 b)
- measure with a rule distance L between balancing machine wall and the rim of the wheel
mounted in wheel chuck (measurement in centimetre)s
- multiply the measured value by four and subtract three, according to formula:
DISTANCE = (4 x L) - 3
