4.10 MACHINE USE WITH ONE CIRCUIT FOR BRAKING (TENSIONER) AND THE OTHER FOR
RECOVERY (PULLER)
To set the 1 capstan circuit for recovery (puller) follow these instructions:
a. Increase the Diesel rpm till the max. value (2600 rpm) acting on the accelerator (table 4, pos. 3).
b. Check the selector is leftwards (table 4, pos. 22).
c. Move the selector (table 4, pos. 13) towards position (BLOCKED).
d. Move the selector (table 4, pos. 38) rightwards.
e. pre-set the desired recovering value:
1. slightly move downwards the joystick (table 4, pos. 11
) into “RECOVERY” position
;
2. turn the valve (table 4, pos. 12) till reading on the dynamometer (table 4, pos. 14) the desired
pull value (puller scale);
3. return to centre with the joystick (table 4, pos. 11).
f. Move the selector (table 4, pos. 13) towards position (FREE).
g. Move the joystick (table 4, pos. 11) towards (recovery) to turn the capstans, the pull is
controlled in the dynamometer scale (table 4, pos. 14).
To set the c capstans circuit for the braking (tensioner) see cap. 4.7.
The same setting can be done on inverted circuits.
4.11 MACHINE USE AS PULLER (RECOVERY FUNCTION) FOR THE CONDUCTORS ON
CAPSTANS
a) Increase the Diesel rpm till the max. value (2600 rpm) acting on the accelerator (table 4, pos. 3).
b) Turn the selectors (table 4, pos. 33,38) rightwards.
c) Turn the potentiometers (table 4, pos. 12,16). till the max. value (10).
d) Move the joystick (table 4, pos. 11) towards (release - upwards).
Now it is possible to let the bull-wheels turn moving the selectors (table 4, pos. 13, 17) towards
position (FREE).
e) It is possible to regulate the circuit pressure (max. 240 bar) acting on the potentiometers
(table 4, pos. 12,16). The pressure can be read on the dynamometers (table 4
, pos. 14,18), “puller”
scale.
f) To stop the machine, turn slightly the potentiometers (table 4, pos. 12,16) in counter-clockwise
direction till the bull-wheels rotation can be interrupted.
g) Move the joystick (table 4, pos. 11) on central neutral position.
h) Move the selectors (table 4, pos. 13,17) towards position (BLOCKED).
NOTE: if necessary to use only right or left bull-wheels, act as described above, but
only on one circuit.
NOTE: if the bull-wheels are mechanically or hydraulically connected (selector
table 4, pos. 22 placed rightwards), the vacuum brakes can be controlled only by the
selector (table 4, pos. 17), the brake by the potentiometer (table 4, pos. 16).
4.12 MACHINE USE AS PULLER (RECOVERY FUNCTION) FOR THE CONDUCTORS
SAGGING REGULATION
a) Increase the Diesel rpm till the max. value (2600 rpm) acting on the accelerator (table 4, pos. 3).
b) Turn the selectors (table 4, pos. 33,38) rightwards.
c) Turn the potentiometers (table 4, pos. 12,16). till the max. value (10).
