6. START-UP
6.1. Control board connection
Before attempting any work on the board (connections,
programming, maintenance), always turn off power.
Follow points 10, 11, 12, 13 and14 of the GENERAL SAFETY
OBLIGATIONS.
Following the instructions in Fig. 3, route the cables through the
raceways and make the necessary electric connections to the
selected accessories.
Always separate power cables from control and safety cables (pushbutton, receiver, photocells, etc.). To avoid any electric noise
whatever, use separate sheaths.
6.1.1. Earthing
Connect the earth cables as shown in Fig.16 ref.A.
Fig.16
6.1.2. Electronic control unit
In the gearmotors, the electronic control unit is fitted to an
adjustable support (Fig. 16 ref. 1) with transparent lid (Fig. 16 ref.
3).
The board programming push buttons (Fig. 16 ref. 4) have been
located on the lid. This allow the board to be programmed without
removing the lid.
For correct connection of the control unit, follow indications the
specific instructions:
Notes on rack installation
• Make sure that, during the gate travel, all the rack elements
do not exit the pinion.
• Do not, on any account, weld the rack elements either to the
spacers or to each other.
• When the rack has been installed, to ensure it meshes correctly
with the pinion, it is advisable to lower the gearmotor position
by about 1.5 mm (Fig.15).
• Manually check if the gate correctly reaches the mechanical
limit stops maintaining the pinion and rack coupled and make
sure there is no friction during gate travel.
• Do not use grease or other lubricants between rack and pinion.
Fig.13
Fig.14
6.2. Positioning the limit switches
The operator has a mechanical travel stop
with spring-lever, which commands gate
movement to stop when a profiled steel plate,
secured on the top of the rack, activates the
spring until the microswitch is tripped. The plate
support can be fitted to all racks with max.
width of 13 mm.
Procedure for correct positioning of the two
travel stop plates supplied:
1) Fit and secure the 2 profiled steel plates on the 2 U-supports,
using the supplied nuts and washers, as shown in figure 17.
2) Prepare the operator for manual operation as described in
paragraph 8.
3) Power up the system.
4) Securing the opening limit switch: manually take the gate to
opening position, leaving 20 mm from the mechanical travel
stop.
5) Allow the plate to slide over the rack in opening direction
(Fig.18). As soon as the opening limit switch LED on the control
board goes off, take the plate forward by about 20÷30 mm
and secure it provisionally on the rack, using the supplied screws.
6) Repeat the operations at points 4 and 5 for the closing limit
switch, Fig. 19.
18
Fig.17

Fig.18
Important:
a) The plate must activate the limit-switch on the profiled part as
shown in figure 20.
b) If the wheel and the travel stop plate are too close, it may be
necessary to shorten the limit-switch spring by a couple of turns.
Procedure for shortening the spring:
- To remove the spring, turn it clockwise. This operation requires
some force.
- Shorten the spring as shown in Fig. 22: two turns correspond
to about 3 mm.
- Fit the spring turning it clockwise, Fig. 23, until the stop is
reached; see Fig. 24.
- Once the spring is back in place, ensure the wheel is horizontal.
A wrong wheel orientation may jeopardise the operation
of the limit switches.
