ELECTRICAL CONNECTION OF THE ENCODER
The S450H operator is fitted with an encoder system. The proper assignment of the leaf to the corresponding encoder depends
on the connection of the two encoder wires (leaf 1- encoder 1; leaf 2 - encoder 2).
THE ENCODER WIRES MUST BE CONNECTED TO THE BUS CONNECTOR OF THE ELECTRONIC EQUIPMENT.
To verify the proper combination
LEAF 1 - ENCODER 1 - MOTOR 1
and
LEAF 2 - ENCODER 2 - MOTOR 2
, refer to the LEDs
on the encoders, as shown in Table 2 and Figures 19, 20 and 21.
To invert the leaf-encoder combination, change the encoder polarity by swapping its wires until the right LEDs are lit.

DL 1: must always be ON
to ensure the right connection between encoder and board.
DL 2: identifies the leaf to which the encoder is installed.
If the encoder is installed on leaf 1, the DL 2 LED is ON.
If the encoder is installed on leaf 2, the DL 2 LED is OFF.
DL 3:
when
blinking
at regular intervals, it signals the pulse reading
during the leaf
movement. When the gate leaf is stationary, DL 3 is OFF.
If the gate is to be operated manually because of a power failure or an automated system fault, activate the release device.
1. Lift the protection lid (Fig. 18, Ref. a) and insert the key in the lock (Fig. 18, Ref. b).
2. Turn the key 90° clockwise to open the cover and lift it.
3. Turn the release knob (Fig. 18, Ref. c) counter-clockwise until it stops.
4. Open or close the leaf manually.
To restore the normal operation of the automated system, perform the above described operations in reverse order.
Models S450H and SB are not equipped with a release facility because, thanks to the particular configuration of the hydraulic
distributing flange, you do not need to release the operator to manually move the leaf.
