GEAR MOTOR RELEASE AND LOCK PROCEDURE
These two operations are required only in the event of a fault or power failure, and the user or assigned personnel must be
trained by the installer, who should provide a copy of these instructions to be kept with care together with the release key.
Before performing either of these procedures, ensure that the power supply is disconnected from the entire
automation, even in the event of a power failure.
RELEASE: 1) insert the key and turn clockwise 2) pull the lever through approx. 90° 3) the motor is released and the leaf can
be moved manually. To keep the leaf blocked, proceed as follows.
LOCK: 4) close the lever 5) turn the safety key anti-clockwise; the gearmotor is then locked and the leaf can only be moved
electrically.

during installation.
ENCODER
The control unit is equipped with an encoder input. This device allows the gate movement to be adjusted with precision and the anti-
crushing protection is guaranteed throughout gate travel, including deceleration.
During the gate travel programming stage, if LED L1 flashes, this means the control unit has detected the presence of the encoder. If,
however, LED L1 remains on constantly, this indicates the control unit will not work correctly with the encoder.
USE OF THE OC2 RECEIVER
The operation and programming of the OC2 series receiver is outlined in the instructions supplied with the receiver.
Please note that the receiver channel 1 always corresponds to the step-by-step (P/P) control on the control unit, while channel 2 is
allocated to the pedestrian control.
PHOTO TEST
For the photo test to work, the system must have two power supply lines for the photocells, the first being connected to terminals 10
and 11, which power the receivers, and the second to terminals 12 and 13, which power the transmitters (the photo test must be
enabled with dip-switch No. 7 in the ON position). The control unit checks the efficiency of the photocells by simulating an activation
at every start of gate movement. If everything is OK the motor starts up, thereby starting the gate movement; if the receiver has any
problems the cycle stops and the open gate light blinks several times to warn of the situation.
- The photo test also works with photocell 2 (Jolly input).
- With the photo test enabled and the control unit in standby, the photocell transmitters are not powered and the FT1 input is open
(LED off). Operation of the photocells may still be checked in this condition by short-circuiting the test jumper (part.12 di Fig 1).

13) Encoder connector
14) Terminal board for low tension connections (24V)
15) ECU reset. Shorting the 2 pins for a moment has the
same effect as switching power off then on again.
16) Indicators LEDs for terminal board inputs. LED on =
input closed
17) Programming LED (L1)
18) Connector for Electric Lock Module
19) Terminal board for 230 V connections
20) Terminal board for mains power supply input
21) 6.3 A fuse for line
22) Terminal board for motor and capacitor connection
