6 START-UP OF THE SYSTEM
The procedure for the first start-up of the automated system for shutter
winders R180 and R280 is of key importance for correct, automatic
adjustment of the travel limit devices.
The travel limit unit of automated system R180 and R280, was designed
and assembled to allow the travel limit devices to be automatically
positioned with a single opening movement.
Carry out the following procedure:
With the shutter completely closed, remove the service bracket (ref.
fig. 11) from the travel-limit unit;
Command complete opening until the mechanical stop point or
the desired height is reached;
According to the type of electric command used,
make sure that the opening movement is constant
along the entire travel. Do not interrupt the rise motion
until the opening height is reached.
Command a complete closure after having reached the opening
position (determined by travel limit stop or by customer’s choice).
The automatic setting procedure for the travel limit devices has ended;
carry out some movements to check if the opening and closing stop
positions are as required.
To further fine tune these positions, consult paragraph 6.1 “MANUAL
ADJUSTMENT OF THE TRAVEL LIMIT DEVICES”.

6.1 MANUAL ADJUSTMENT OF THE TRAVEL-LIMIT DEVICES
If you wish to modify/fine tune the automatically set opening and closing
positions, proceed as follows:
Take the shutter into its fully closed position, to obtain full access to
the travel limit unit;
1.
As shown in Figure 14, incline downward and keep inclined the
rotation constraint lever (ref.
) to enable release of the travel-limit
devices screws;
Turn the travel-limit devices screws clockwise or anti-clockwise
to anticipate or delay the activation of the opening or closing
microswitches;
Release the rotation constraint lever and perform a few movements
to check the effect of the modifications;
Repeat the procedure till obtaining the motor stop in the required
positions.

Electro-brake assembly procedure:
Fit the supplied cable inside the body of the electro-brake until it
comes into contact with the end ball (Fig.15);
Fit the sheath of the cable until it comes into contact with the
electro-brake body (Fig.15);
1.
2.
Assemble the electro-brake in Figure 16 on the cover of the electric
motor with screws ref.
and washers ref.
, mating the motor shaft
ref.
with the electro-brake block;
3.
Use the hole (Ø 15 mm), previously drilled for routing the power
cable, to insert the sheath-cable unit into the shutter shaft (Figure
17). Take care not to bend the sheath too much in order to allow
the cable to freely move inside.
4.
The electro-brake is an accessory that guarantees maintaining the
position of the shutter at whatever height it is left.
In fact, the electro-brake acts on the motor shaft, locking it at the end
of each electric movement, thus ensuring that the shutter cannot
be manually moved or lose its position due to imbalance of the
compensation springs.
