To program the same pull value simultaneously on all circuits:
1. Move the joystick downwards (tab.4, pos.11) on recovery position
2. Turn the potentiometer (tab. 4, pos. 12) until read on the dynamometer (tab. 4, pos. 14) the
desired pull value (puller scale)
3. Move to center the joystick (tab. 4, pos. 11).
NOTE: to visualize the set pull on the slave machines dynamometers move the selector
rightwards (tab.4, pos.39). Although not be displayed, the pull value is set.
To use the machine for an independent braking:
a. Verify that the bull-wheels coupling pin (tab. 5) is out (FREE).
Otherwise, proceed to draw.
b. Move the selector (tab.4, pos.17) rightwards on the master machine to select all the circuits
for the negative brake opening
c. Control that the joystick (tab. 4, pos. 11) is in neutral position.
d. To unlocked the negative brakes on all circuits move the selector (tab.4, pos.35) rightwards on
the master machine. Now the bull-wheels can turn up.
e. Perform the bull-wheels braking using the potentiometer (tab. 4, pos. 16).
That potentiometer controls both circuits entre the other potentiometer (tab. 4, pos.12) is
disabled. The pressure on the circuits, provided to the pull, is indicated on the manometers
(tab. 4, pos. 14,18). A lock ring promptly graduated mounted on the exterior of them allows to
detect the conductor
’s tension.
PROHIBITION: is not possible move down or up the joystick (tab. 4, pos. 11) of the
central position and put the selectors (tab. 4, pos. 38, 39) on the right, during this
phase. It can cause serious damage to the machine.
In case is passed to independent configuration, disconnect the machines after make sure that the
negative brakes are blocked. Remember that the circuits potentiometers might not have the same
value of the circuit potentiometer with the higher ID on the master machine.
f. Insert the pull synchronism positioning the selector (tab.4, pos.37) on the right of the master
machine
ATTENTION: before insert the synchronizer make sure that the head boards, arrive to
aprox. 50m from the brakes, is on the correct work position and no twisted or rotated. That is
equivalent to having all the heads of the conductors lined up in a single share. If it were
otherwise recover or drop one or more conductors to obtain such a result because initial gap
of one conductors bundle not lined synchronizer is not recovered if not maintained.
ATTENTION: The synchronizer fails to maintain lined the conductors in line sections
where have been accentuated directional variations. In this situation disconnect the machines
and line the conductors one at a time as described on the paragraphs from the los cap. 4 and 5.
DANGER: To avoid turn off one of the connected machines if before not been closed
negative brakes moving leftwards the selectors (tab.4, pos.13,17) of all machines. Run the risk
to lose the pull.
DANGER: To avoid disconnect the connection cable between the machines if before not
been closed negative brakes moving leftwards the selectors (tab.4, pos.13,17) of all machines.
Run the risk to lose the pull.
