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 10Amagnetothermic 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:

- 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,

- 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

edges 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.



Slide the gate manually until it is approximately 5 cm away from the mechanical end stop

Position the sliding plate so that it controls the microswitch actuator spring; you should hear a click as the

microswitch flips when the sliding plate passes it

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.

CAUTION:

For safety reasons, an

end stop must be fitted for

both the closure and

opening movements

DESCRIPTION OF OPERATION

CAUTION: with the force limitation feature deactivated,

other safety devices must be adopted (e.g. sensitive edge),

which must be compliant with regulations in force.

Input for photocell active during both closure and opening: if the

photocell is obscured during opening, the gate stops moving, but starts

again as soon as the photocell is clear; if the photocell is obscured

during closure, the gate will stop moving, and then start opening again.

Force limitation activated: in the event of an impact with an obstacle,

whether during opening or closure, an encoder system detects the

impact, stops the gate and then reverses it by 10cm see Page 12.

Pre-flashing disabled: the flashing light switches on at the same time

as the gate starts opening.

3.8 OBSTACLE IMPACT CONTROL AND MOTOR FORCE ADJUSTMENT

With the SW2 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 SW2 microswitch 1 in the ON status; 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

impact force is adjusted using the VELOCITA REGIME potentiometer during the normal working phase and using

the VELOCITA RALLENTAMENTO potentiometer during the slow-down phase; the adjustments must be performed

in compliance with the regulations in force.

3.9 CR/42 CONTROL UNIT TECHNICAL SPECIFICATIONS

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.

3.6 BATTERIES BACKUP (OPTIONAL)

It is possible to connect inside the MERCURIO 524 A two backup batteries

(2Vdc 1,2 Ah SERAI BT/14), in order to enable the automation to work for

a short period also in case of power failure. The batteries have to be

connected in series (see Picture aside); the positive cable has to be

connected to the clamp 2 (BATTERY +) and the negative cable to the

clamp 1 (BATTERY )

3.7 MOTOR WORKING WITHOUT ENCODER

The control panel CR/42/24 has been conceived to work also without ENCODER, therefore can be used also

with other kind of motors 24Vdc. The control panel can be enabled to work without encoder acting on the micro

switches SW1 and SW2; in this case it is not necessary any programming, being the working phase between the

limit switches.

3.10 CR/42/24 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 DL8 LED will start flashing, indicating that the control unit has entered the programming phase.

The next section deals with the CR/42/24 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) 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.

3.10.1 PROGRAMMING THE WORK TIMES AND IMPACT FORCE SETTING MANUALLY

The 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 VELOCITA RALLENTAMENTO 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, press the LAVORO

(Operation) button once: the gate will start opening.

During the opening manoeuvre, adjust the VELOCITA REGIME trimmer to set the force that will be applied

during il normale funzioanmento (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 and dip4 SW1 ON.

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

3.10.2 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 DL8 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 DL8 LED will start flashing, indicating that the card has entered the programming phase.

Press the PAUSA (Pause) button and keep it pressed until the DL8 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 LEARNING

The 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 PREVENT

UNWANTED 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 CODES

All 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 DL8 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 DL8 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 DL8 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 DL8 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 DL8 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 TRANSMITTERS

If 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 794).

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

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).
