CHAPTER 1: GENERAL INFORMATION1.1 KIT CONTENTS

1.2 WIRING EXAMPLE FOR KIT CONTENTS

Advice for wiring up in non-specialised environments.1. Fit an omnipolar switch upstream of the system, choosing one with a gap of at least 3 mm between the contacts. Or,

alternatively, use a 10A magnetothermic switch.2. When making the connections (using any type of connector), ensure the system is disconnected from the power

supply, i.e. that the main switch is in the “open” position (“0” symbol). The control unit, in particular, must never be connected to the power supply either during the wiring up, or when fitting any expansion cards.

3. The following cables must be used for installation of the system:2 2- for the control unit and motor power supplies: 1.5 mm section for lengths of up to 19m, 2.5 mm section for

lengths of up to 31 m,2 2- for the flashing light: 0.75 mm section for lengths of up to 3 m, 1.5 mm section for lengths of up to 19 m.

- for the low voltage and current lines (e.g. For the photocells, control buttons, electromechanical key, sensitive 2 2edges and other safety devices): 0.5 mm section for lengths of up to 50 m, 0.75 mm section for lengths of up to

100 m.4. Wire up the earth connection in compliance with legal provisions.

CHAPTER 2: MOTOR INSTALLATION

2.1 BEFORE STARTING

� Check that the gate is equipped with sturdy support rails

� Check that the rail is anchored securely to the ground

� Fit two sturdy mechanical stops at the two ends of the rail

� Check that the gate runs smoothly along the rail

The installation of the mechanical end stops for gate opening and closure is necessary for system safety purposes and therefore this operation must be performed before proceeding with the installation of the control unit.

2.2 INSTALLING THE BASE PLATE

2.2A

� Screw the two nuts onto the bolts, until they are positioned 35 mm from the end of the thread

� Fit the J bolts through the holes in the base plate

� Screw the other two nuts onto the J bolts without tightening

2.2B

� Dig a hole and place the base plate (fastened to the bolts) inside it, along with the cable carrier hose

� Position the base plate at the heights specified, fastening it so that it stays flat

2.2C

� Cast concrete to secure the unit to the ground, ensuring all the base plate parts are kept clean and the two nuts are out of the concrete completely.

� Wait for the concrete to harden, then remove the two nuts

CAUTION:If the motor is located in an area prone to flooding, the base plate must be positioned high enough to stop the water reaching the motor

� Slide the gate and position the sliding plates so that they command the micro switch control spring. You must hear a click.

CAUTION:- To guarantee correct limit switch operation, ensure there is a distance of 30 mm (tolerance: ±

5 mm) between the side of the motor and the sliding plate. A gap of over 35 mm may cause the gate to jam open or closed. A gap of under 25 mm may cause breakage of the limit switch control spring.

- The end stop sliding plates must be set (taking into account inertia and changes in temperature) so that the gate never ends up resting on the mechanical end stops during opening and closure. If this occurs, the FLAP COULD GET BROKEN during the release operation. Because of seasonal temperature differences, we recommend you check this in both summer and winter.

ND3.6 GATE OPEN INDICATOR LIGHT AND 2 STARTING RELAY (RELAY MODULE MR/08)

NDThe “INDICATOR LIGHT 2 C” connector located between the two terminal boards serves to connect relay module MR/08 SR 24.08 (optional for 300-500 kg motors, standard on 800 kg motors), which allows:1- an optical signalling device to be located inside the building. In more detail, the NO/C terminals (clean relay

contact 3A 250Vac) can be used to provide the following signals:

Light lit permanently: gate is open and stationaryLight flashing slowly: gate opening manoeuvreLight flashing fast: gate closure manoeuvre

2- a second starting capacitor to be connected, which remains active for approx. 2 s every time the motor starts. In the 800 kg version, this allows the starting force to be increased and reduces motor heating

With the SW1 microswitch 1 in the OFF status, obstacle impact is detected (during both the opening and closure manoeuvres) by the encoder system which stops the gate moving and then reverses it by approx. 10 cm. This control is switched off with the SW1 microswitch 1 in the ON status; in this case, other safety systems compliant with regulations in force (e.g. sensitive edges) must be adopted.

The impact force is adjusted using the REG potentiometer during the programming phase and adjustments must be performed in compliance with the regulations in force.

CAUTION: The considerable differences in temperature between summer and winter can cause differing rates of expansion in all materials, including those used for manufacturing our motors. That is why we recommend you check the impact force setting at the start of winter and summer.

THE INSTALLER IS LIABLE FOR THE SYSTEM AND FOR ENSURING ITS OPERATION COMPLIES WITH LEGAL PROVISIONS

The sensitive edge can be fitted both on the fixed parts as well as on the gate itself (in front and back of the gate) and can be connected to the input 12 or in series to the stop or in series to the photocells, according to the protection requirements deriving from the laws in force.

3.9 CR/42A CONTROL UNIT PROGRAMMING

With the control unit powered, release the gate, open it approx. 2 metres, then relock it. Press the PROG, button once; the DL10 LED will start flashing, indicating that the control unit has entered the programming phase.

The next section deals with the CR/42A control unit programming.It is important to follow the programming step by step; in the event of errors during this stage, a new programming session must be performed, in which case the new data will replace the previous data.To quit an incorrect programming session, switch the control unit off then on again.

Before proceeding with the programming, check that the system is equipped with all the electrical and safety devices (buttons, photocells, flashing lights, etc.) and that they are all connected. Ensure they all operate correctly, i.e.:

All the indicator LEDs for the NC inputs (stop, photocell, limit switch, sensitive edge) are lit; All the indicator LEDs for the NO inputs (open/close, pedestrian) are off.

In the event of faults, ascertain and remove the cause.

CAUTION: ANY UNUSED NORMALLY CLOSED (NC) INPUTS MUST BE JUMPERED.

3.9.1 PROGRAMMING THE WORK TIMES AND IMPACT FORCE SETTING MANUALLYThe deceleration point is set by the installer and can be cut out

Press the WORK button once to start the closure manoeuvre. The sliding gate will begin the closure manoeuvre with a starting thrust and will then decelerate and continue at a slow pace.During slowing down, adjust the REG trimmer to set the force that will be applied during deceleration (in the event of impact with an obstacle).

Once the closure manoeuvre is complete and the FCC (closure limit switch) LED is off, set the REG trimmer back at half stroke.

Press the LAVORO (Operation) button once: the gate will start opening.During the opening manoeuvre, adjust the REG trimmer again to set the force that will be applied during deceleration (in the event of impact with an obstacle).

Before the gate completes the opening manoeuvre, press the LAVORO (Operation) button (we recommend doing this when it is 50 cm away from the end stop). This sets the desired deceleration start point, and the gate will start the deceleration phase.N.B. If you wish to deactivate deceleration during normal operation cycles, skip this step.

As soon as the gate has completed the opening manoeuvre, the work cycle is acquired, as is the deceleration point, if set. After a few seconds, the closure manoeuvre starts, and the programmed deceleration is applied.

When the gate reaches the closure limit switches (FCC LED off), the control unit automatically quits the programming phase and switches to standard operation mode.

CAUTION: If one or more parameters are altered, programming must be repeated from the beginning.

Page 12/16

3.9.2 GATE OPEN PAUSE TIME PROGRAMMING

With the control unit powered and the gate closed (closure limit switch FCC - LED off), press the PROG, button once; the DL10 LED will start flashing, indicating that the card has entered the Programming phase.

Press the PAUSA (Pause) button once, keeping it pressed until the flashing light comes on; the control unit will start the gate open pause count, which is indicated by the light flashing intermittently.

Once the desired time has lapsed, press the PAUSA (Pause) button again; the control unit will automatically store the amount of time between the two times the PAUSA (Pause) button was pressed. It then quits the programming phase and switches to standard operation mode.If the PAUSA (Pause) button is not pressed a second time within 120 s, the control unit quits the programming, memorising the maximum time as 120 s.

ACTIVATING AUTOMATIC RECLOSURE (max time settable: 120 s)

With the control unit powered and the gate closed (closure limit switch FCC - LED off), press the PROG button once; the DL10 LED will start flashing, indicating that the card has entered the programming phase.

Press the PAUSA (Pause) button and keep it pressed until the DL10 LED switches off. The control unit quits the programming phase and switches to standard operation mode. This operation deactivates the automatic reclosure function.

CHAPTER 4: MINI TRANSMITTER CODE LEARNINGThe electronic card incorporates a 433.92 MHz 2-channel radio receiver which allows remote gate control via either the OG/02 and OG/04 series microswitch-operated mini transmitters or the self-learning mini transmitters from the following series: OG/62, OG/64, OG/28, OG/48, OG/52, OG/54, OG/82/1 and OG/84. Both channels are used solely for gate control; more specifically, channel 1 of the radio receiver serves for the open/close function, while channel 2 is used for the pedestrian function.

!CAUTION: - a mini transmitter must be programmed before it is used.

- the maximum number of codes that can be stored is 32 for the open/close control + 32 for the pedestrian control (no other combinations, e.g. 40 open/close + 24 pedestrian etc, are possible). Let's have a look at two examples of storable codes:

- example A: 32 self-learning mini transmitters from the following series: OG/62, OG/64, OG/28, OG/48, OG/52, OG/54, OG/82/1 and OG/84 as the open/close control (e.g. left-hand button) + 32 self-learning mini transmitters from the following series: OG/62, OG/64, OG/28, OG/48, OG/52, OG/54, OG/82/1 and OG/84 as the pedestrian control (e.g. right-hand button)

- example B: 31 self-learning mini transmitters from the following series: OG/62, OG/64, OG/28, OG/48, OG/52, OG/54, OG/82/1 and OG/84 as the open/close control (e.g. left-hand button) + 1 OG/02 or OG/04 series microswitch-operated mini transmitter as the open/close control (there is no need to store the other OG/02 and OG/04 transmitters, simply set the microswitches in the same sequence as the one already stored) + 31 self-learning mini transmitters from the following series: OG/62, OG/64, OG/28, OG/48, OG/52, OG/54, OG/82/1 and OG/84 as the pedestrian control (e.g. the right-hand button) + 1 OG/02 or OG/04 microswitch-operated mini transmitter as pedestrian control (there is no need to store the other OG/02 and OG/04 transmitters, simply set the microswitches in the same sequence as the one already stored)

MODIFYING THE FACTORY-SET CONFIGURATION TO PREVENTUNWANTED COMMANDS

MICROSWITCH CONFIGURATION (FOR OG/02 AND OG/04 MINI TRANSMITTERS ONLY)These instructions only apply if the OG/02 and OG/04 series microswitchoperated mini transmitters are fitted. Before performing the code learning procedure on the receiver, the factory-set configuration of the microswitches must be modified to prevent unwanted commands

CAUTION: before proceeding with the mini transmitter programming or clearing phase, disconnect the antenna to prevent the receiver from acquiring other signals during these phases which could impair automation operation. Reconnect the antenna once the procedures are complete.

4.2 CLEARING OF STORED CODESAll the radio codes stored in the memory can be cleared by pressing the PROG and PAUSA keys AT THE SAME TIME, and keeping them pressed until the DL10 LED switches off (approx. 10 s) without sending any radio codes during this time. This operation clears all the codes associated to both the open/close and the pedestrian control.

OPEN/CLOSE CODE LEARNING - With the control unit powered and the gate closed, press the PROG key once to enter the programming phase.

The DL10 LED starts flashing to indicate that the control unit is in the programming mode.- Press the button on the mini transmitter (the left-hand one, for example) which you wish to serve as the

open/close control, and keep it pressed until the DL10 LED switches off. The control unit stores the radio code received and automatically quits the programming phase, switching to the standard operation mode.

- Repeat the procedure if several mini transmitters need to be stored.

PEDESTRIAN CODE LEARNING- With the control unit powered and the gate closed, press and hold down the PROG key to enter the programming

phase. The DL10 LED starts flashing to indicate that the control unit is in the programming mode.- Keeping PROG pressed, push the button on the mini transmitter (the right-hand one, for example) which you wish

to serve as the pedestrian control, and keep the two buttons pressed until the DL10 LED switches off. The control unit stores the radio code received and automatically quits the programming phase, switching to the standard operation mode.

- Repeat the procedure if several mini transmitters have to be stored.

4.3 EXPANDING THE NUMBER OF MINI TRANSMITTERSIf the 32 mini transmitters storable in the built-in receiver are not sufficient, they can be increased by fitting the SOG/4A receiver (which increases the number of mini transmitters up to 40), possibly with the addition of the SOG/2A expansion card (which increases the number of mini transmitters up to 834). After fitting the SOG/4A receiver, all the codes stored in the built-in receiver must be cleared and all the mini transmitters on the new SOG/4A receiver reprogrammed (see specific instructions). The antenna must be mo-ved from the terminals on the control unit to the terminals on the SOG/4A

CHAPTER 8POWER CUT - manual gate release -

8.1 A � Fit the release key into the lock on the front panel of the motor unit and turn it anticlockwise by a half turn.� Push the release flap hard downwards until the release

mechanism is triggered.� The gate can now be moved by hand

CAUTION: The gate must not be resting on the mechanical end stops, otherwise the force required to perform the release manoeuvre would break the flap

8.1 B � To relock the gate, lift the release flap and remove the key from the lock cylinder.� Open or close the gate a few cm by hand until the stop pinion

locks, ensuring the limit switch has been pressed.

1/2

In the event of a power cut, the gate can be moved manually by releasing the motor as shown above.CAUTION: if the gate is in an intermediate position (one of the limit switches has not been pressed) when power is restored, the next time the open command is sent, the manoeuvre will be performed in deceleration mode for a maximum time of 300 s. If, during that time, the limit switch is still not reached, the subsequent closure manoeuvre will be performed normally. To prevent this, the gate must be moved during the power cut to either the fully open or the fully closed position (so that one of the limit switches is pressed).

Unsuitable limit switch setting

Check and adjust the position of the end stop sliding plates and that they activate the control spring.

PROBLEM CAUSE SOLUTION

The gearmotor is not working Fuse fault Replace the fuse.

No power

The gate does not move or the motor slips

Obstacle impact control cutting in

Motor force setting not optimal

Repeat the work times and impact force setting programming.

Capacitors worn out Measure the capacitances of the capacitors and if necessary, replace them.

Motor thermal protection cutting in

Leave the motor stationary for at least 5 minutes and then check operation again.

The gate does not complete its travel

The gate has difficulty starting

Unsuitable gearmotor position

Check that the distance between the end stop sliding plate and the front, outgoing trim of the spring is between 25 and 35 mm.

Unsuitable limit switch sliding plate setting

The gate is jammed against the mechanical end stop

Remove the lower casing from the motor.Unscrew the nuts fastening the base plate bolts.Remove the motor from its position by releasing the pinion from the tooth rack.By hand, move the gate right away from the mechanical end stop.Release the motor manually.Reposition the motor on the base plate.Set the end stop sliding plates properly.Replace the lower casing and secure the motor.If necessary, repeat the work times and impact force setting programming.

Check the motor power supply input terminals to see if they are live.Check that the power supply cable is not cut or broken (cable replacement must be carried out by an authorised technician).

Release the gate manually and check that there are no obstacles. If obstacles are found, remove them.Repeat the “work times and impact force setting programming” procedure, setting a greater force.N.B. The impact control can be switched off by positioning the

SW1 microswitch 1 to ON; in this case, other safety systems compliant with regulations in force (e.g. sensitive edges) must be adopted. This is extremely important as THE INSTALLER IS LIABLE FOR THE SYSTEM AND FOR ENSURING ITS OPERATION COMPLIES WITH LEGAL PROVISIONS.

The remote control range is reduced

Unsuitable antenna connection

Check that the antenna is connected correctly to terminals 21 and 22.

External antenna required

To permit maximum reception distance, replace the internal antenna on the flashing light with an external one (SERAI OG/50 -SR 25.50).

SOG/4A receiver in use

Replace the built-in receiver with the SOG/4A card.

The first opening manoeuvre takes place during deceleration (if the gate is in an intermediate position) and can take up to 300 s; if it does not occur within this time, the gate must be moved to the fully open or fully closed position by hand (see chapter 8).
