ENGLISH
• remove the screws which fasten the rod carrier plate, fig. 9
and 10.
• rotate the rod carrier plate, ref.2 fig. 9 and 10, by 90°.
• re-fasten the whole assembly with the screws.
To fit the beam, follow the instructions below, according to the
automated system model:
617/3 - 617/4 (Fig.11)
• put the rod carrier plate in horizontal position.
• fit the beam, ref.1 fig.11.
N.B.: The rubber profile. ref.2 fig.11 must face the closing
direction.
• screw the four supplied screws, ref. 3 fig.11.
• insert the hole plug, ref.4 fig.11.
617 (Fig.12)
• put the rod carrier plate in vertical position.
• fit the beam, ref.1 fig.12.
N.B.: Beams for 617 models are ambidextrous
• position the “C” support, ref. 2 fig.12, and tighten the six supplied
screws, ref.3 fig.12.
• adjust the mechanical stops, fig. 13 ref.1 and 2.
• adjust the activation cams, fig. 14 ref.1 and 2, of the stroke-
limit microswitches so that they are activated with the rod in
opening or closing position just before their respective
mechanical stops.
4.4. INSTALLING AND ADJUSTING THE BALANCING SPRING.
The automated system requires a balancing spring, fig.15 ref.1,
which must be ordered separately (like the beam). The type of
spring to be fitted must be selected according to the length of
the beam and of any installed accessories (see chap.8), selecting
the spring from among those in the price list.
Spring installation and adjustment procedure:
• check if the operator is released: see chap. 6
• remove the tie-rod, fig 15 ref.3.
• while keeping the beam always in vertical position, connect
the spring to the plate, fig.15 ref.2. For
quicker installation, we recommend
keeping the open part of the eyelet
facing toward the installer.
• fit the tie-rod, fig. 15 ref.3, into the lower
eyelet and in its securing hole.
• tighten one of the two nuts, fig. 15 ref.4,
until you recover all backlash on the
spring.
• position the beam at 45° and, turning
the nut you have just tightened, pull the
spring until you balance the weight of
the rod in this position.
• tighten the second nut and secure the
whole assembly.
• restore normal operation as in chap. 7.

5. START-UP
• install the electronic control unit, observing the supplied
instructions.
• check if motor connection is correct, in the following steps:
• set the operator to manual operation, see chap.6.
• position the beam at 45°, so that the two microswitches are
not activated.
• re-fasten the operator, see chap.7.
• power up the system and provide a pulse with the start
command. The first manoeuvre to be performed by the beam
must be opening. If the beam starts with a closing cycle, cut
power and reverse the phase wires of the control unit terminals.
• power up again and repeat the check.
• check the efficiency of the limit-switches, checking the status
of the LEDs on the control unit.
