2. General description

The

IT24, Beninca

is an underground swing gate operator designed for domestic and lightindustrial applications where the operator is hidden from view. It is also useful in applications where the gate swings hard up against its side wall leaving absolutely no space to mount a traditional above-the-ground unit.

The operator consists of a high-torque 24V DC motor coupled to a double-stage worm reduction gearbox housed inside a steel foundation box. The assembly is mounted flush with the ground, up against the gate support pillar, directly under the gate hinges. Its output drive arm extends upwards from the operator linking with a drive shoe that is welded to the underside of the gate.

The drive arm, drive shoe and operator cover plate are the only parts that are visible. The gate is supported by the operator with the bottom gate hinge removed. Only the top hinge is left to stabilize the top of the gate.

To ensure rigid closing of the gate in the closed position, end-of-travel mechanical endstops must be installed. In addition, if the gate leaf is wider than 2.5m, an electric lock must be fitted, and on any width if maximum security is required.

The internal mechanical limit switches can be used to stop the gates in the open position, the alternative being mechanical endstops.

A Manual Override with key release is incorporated into the drive arm assembly.

The operators are battery driven via the CP77/24V dual motor controller, which supports a host of useful features in addition to providing smooth acceleration of the motors on start-up, safe protection against crushing and critical power failure protection.

7. Preparation of site

General considerations for the installation

 Always recommend the fitment of additional safety equipment such as safety edges and safety beams, for additional protection against entrapment or other mechanical risks

 Check that no pipes or electrical cables are in the way of the intended installation



Check that it is possible to mount the foundation box directly beneath the gate hard up against the support pillar noting that the output shaft is vertically below the centerline of the hinges



Check that it is possible to remove the bottom hinge and allow the gate to be supported by the operator



Check that there is a sufficient gap between the underside of the gate and the ground to accommodate the operator drive arm and drive shoe with the operator mounted flush with the ground

 Check the fixing of the drive shoe to the underside of the gate. With steel gates the shoe can be welded. With a wooden gate, the shoe will have to be bolted to the gate



Check for loose, sandy soil as the soil may require a larger concrete foundation to securely support and locate the foundation box



Check that adequate draining can be provided for the foundation box



If the swing gate leaf is longer than 2.5mm, ensure that a lock can be fitted

 End-of-travel mechanical endstops must be fitted for the gate in the closed position



Should any welding or modifications to the gate be required, this should be done prior to the

Beninca

operator being installed

Install the gate operator only if:



It will not pose a hazard to the public

 There is sufficient clearance to a roadway and/or public thoroughfares



The installation will meet all municipal and/or local authority requirements once completed



The gate mass, leaf width, allowable wind loading and application is within the operator specifications (refer to the specification tables)



The gate is in good working order, meaning:



That it swings freely;

 Does not move on its own if left in any position;

 Each gate leaf is strong and rigid



It can be installed to have sufficient clearance between moving parts when opening and closing to reduce the risk of personal injury and entrapment



Pushbuttons or key switches, when required, can be positioned so that the gate is in line of sight of the operator page 12



All cables must be routed in conduit unless underground cable is being used

Mains isolator must be less than 1m from the operator

Safety beams are always recommended page 14

9. Operator installation

To simplify the installation process, it is recommended that the existing gate is removed from the pillar before proceeding.

Foundation box installation

As the foundation box is liable to fill with water during rainfall, it is critical that an adequate drainage system is prepared.

Refer to step 9.

1. Determine the correct position for the foundation box, i.e.

standard

or

inside

.

Standard mounting configurations

Inside mounting configurations

FIGURE 5. STANDARD MOUNTING CONFIGURATIONS

FIGURE 6. INSIDE MOUNTING CONFIGURATIONS

page 15

2. Dig a hole for the foundation box - the size of the hole being adequate to securely anchor the foundation box taking into consideration:

 Weight of the gate resting on the foundation box



Condition of the soil around the foundation box

3. Cast the base of the hole in a quick-drying concrete, ensuring the base is level and that the foundation box when inserted into position, will be flush with the ground.

4. Fold the two anchor tabs at 45° away from the base of the foundation box just prior to inserting it into the hole. page 16

FIGURE 9

5. Cover the drainage holes on the inside with duct tape.

6. Insert the

foundation box

into the hole.

Ensure the box is placed in a horizontal position, with the casing pivot at exactly 90° to the base, and perfectly aligned with the gate's hinge.

7. Lay a 30mm PVC conduit through the cable hole – the conduit must be routed back to the controller housing.

8. Complete casting the foundation box by filling in around the sides with concrete.

FIGURE 11

FIGURE 12

9. As soon as the previous step is completed, determine the position on either side of the foundation box to which the drainage holes will lead. Prepare drainage shafts as follows:



Dig drainage shafts next to the concrete foundation adjacent to the drainage holes of the foundation box

 Shaft dimensions are approximately -

200mm diameter x 500mm deep

10. Before the concrete has completely set remove the duct tape from the drainage holes and carefully core through the side wall of the concrete foundation into the drainage shaft.

11. Ensure that there is a slope in the coring between the drainage hole and the shaft so that water will be able to drain away.

12. Fill the drainage shafts with crushed stone or pebbles.

Motor and gate assembly

1. Remove the bottom hinge from the gate – only one hinge on each gate is required, with the drive unit itself serving the purpose of the bottom hinge.

1. It is necessary to mount a solid mechanical endstop into the ground. Ensure that the gate leaves stop firmly up against the stop and are perfectly aligned with each other in the closed position.

FIGURE 23

Gate lock

2. For greater security and if the gate leaf is wider than 2.5m, it is recommended that a gate lock is fitted together with the mechanical endstops to fully secure the gates in the closed position.

page 21

Open endstop

3. It is possible to use the internal limit switch to stop the gates in the open position.

4. Alternatively mechanical endstops can be used, mounted where each leaf swings to, in the open position.

5. The

limit switch disc

should already have been mounted onto the motor’s output shaft at an earlier stage.

6. Assemble the microswitch group in either of the positions available, depending on the type of installation.

7. Only one of the two microswitches provided will be used.

10. Electrical setup

1. Always check that the circuit breaker in the electrical panel is in the OFF position, and that all high voltage circuits (more than 42.4V) are completely isolated from the mains supply before doing any work.

2. Ensure that all low voltage systems (less than 42.4V) are suitably protected from damage, by disconnecting all sources of power such as chargers and batteries before doing any work.

3. All electrical work must be carried out according to the requirements of all applicable local electrical codes. (It is recommended that a licensed electrical contractor perform such work.)

Secure control box to wall

1. Secure control box to the wall using the most appropriate means.

Be sure to position the wall box so as not to cause any hazards during and after the installation.

Preferably mount the wall box:

• Out of direct sunlight

• At a comfortable working height

• Away from garden sprinklers etc.

• To allow easy access even when the

gate is open

14. The motor will just stop when the gate(s) hits an obstruction while opening or closing.

15. There are two sensitivity potentiometers on the CP77/24V controller. The left-hand potentiometer is used to set the sensitivity of both the master and slave gate(s) when opening. The right-hand potentiometer is used when the gate(s) are closing.

16. Start with the potentiometers set to a midway position.

17. Trigger the gate(s) and when the gate(s) have traveled approximately halfway through the opening or closing movement, obstruct the gate(s) noting the effort required to stop them.

page 30

FIGURE 41

18. Adjust the respective potentiometer depending on whether the gate was opening or closing, clockwise if the gate stopped too easily or anti-clockwise if the gate was hard to stop.

FIGURE 42

page 31

14. Controller features

Inherent safety features

Safety (Collision sensitivity)

If the gate is obstructed, the internal collision circuitry will activate the gate whether opening or closing to just stop.

The response of the system to a collision will vary according to the sensitivity level that has been set. There are two potentiometers, one for setting the gates while opening and the second while closing.

Clockwise adjustment reduces the sensitivity and increases the push force.



Collision count

A counter monitors the number of collisions that the gate experiences before the gate reaches the fully closed position. If the value exceeds a preset value of four, the controller shuts down

for a period of two minutes. A valid trigger received after this shut-down period will reset the

system.

As an indication, the status LED will flash four times every two seconds. The multiple collision

fault indication will continue to flash indefinitely or until a valid trigger has been received.

Selectable features

Autoclose



Autoclose status

The Autoclose feature when turned on, has the function of automatically closing the gate after an adjustable autoclose time.



Autoclose time

A potentiometer is provided on the controller to adjust the Autoclose time between five and thirty seconds.



Autoclose override

It is possible for the user to temporarily turn off Autoclose. To activate Autoclose override,

press

and hold

the button of the remote or the gate intercom (any device connected to the TRG

input) for at least three seconds. Release the button. The gate will open fully and stay open.

The gate response will be to start opening on the first TRG trigger, and then to stop as soon as the Autoclose override feature is activated. On clearing of the TRG input, the gate will continue opening until fully open. The Autoclose feature is now off and the gate will remain open indefinitely.

The next signal received on TRG will clear the Autoclose override feature, close the gate, and set the Autoclose feature back to normal.

Input features

Gate trigger - Modes of Operation (TRG)

 The CP77 supports three Modes of Operation:

Standard, Condominium

and

PIRAC

.

However, the gate motors rely on a mechanical endstop to stop the gate in the closed position and the controller must be set so that they shut off when the gates reach these limits. This limits the system to STANDARD Mode of Operation.

page 32



Standard Mode via gate trigger

When stationary, a trigger impulse on TRG will cause the gate to either open or close. While the gate is moving, a trigger impulse on TRG will stop the gate. A third impulse on TRG will cause the gate to reverse its direction of travel, i.e. the action is

start

-

stop

-

reverse

.



Pedestrian Opening (PED)

This feature is associated with the PED input on the controller. When activating this input, the system will open the master gate only to the pedestrian open position (fixed width opening of approximately one metre) and then automatically close after a preset pedestrian Autoclose time of five seconds. If activation of the PED input is maintained, the gate will remain open, and when de-activated the gate will close after the pedestrian Autoclose time.



Free-exit input (SP2)

The Free-exit facility is activated by using the dedicated input to the control card marked SP2.

The Free-exit facility allows for easy exit of vehicles from a townhouse or parking lot. When driving through the free-exit beam or over an inductive loop the controller will automatically open the gate. The free-exit beam facility will only open the gate and therefore the Autoclose facility, described earlier, must be enabled to close the gate.



Holiday Lockout (SP1)

When this feature is enabled using typically a latching device connected between this input and

COM, all inputs that can operate the gate are inhibited. The feature is designed so that even if it is enabled while the gate is moving or in the open position, it will only activate when the gate is back in the closed position.

For instance this ensures that while the property is left unattended for extended periods of time, a would-be intruder cannot try and tamper with any of the inputs such as the intercom gate release button, pedestrian keyswitches / keypads to operate the gate. It also automatically disables any free-exit devices such as underground loops, etc.



Infrared safety beams (IRB)

External safety/detection devices are necessary to sense the presence of a person or vehicle moving through the entrance and ensure that the gate cannot be closed onto the obstruction.

By comparison, the inherent safety mechanism described earlier, relies on the gate hitting the obstruction before reacting.

An infrared safety beam is ideal in domestic installations and will accommodate a multitude of potential obstructions such as people, vehicles and pets. However, in industrial applications with mainly vehicles, large and small, moving through the entrance, an underground loop can be a more reliable detection device.

With the gate in the open position and the detection device activated, the gate cannot be closed.

If the gate is already closing when the detection device is activated, the gate will immediately stop and re-open. If the gate is closed or opening and the detection device is activated, the signal from the device will be ignored.

Similarly, if the Autoclose feature is selected, the gate will remain open while the detection device is activated. The moment the detection device is cleared the gate will only close after the preset autoclose time has expired. page 33

Outputs with associated features



Gate status LED (LED)

External gate status indicator. This output provides a low current drive to light up a LED which can be used to indicate the gate status remotely.

For instance if the gate is not visible from the intercom handset inside the house, which is used to communicate with a visitor at the gate and operate the gate, an LED fitted to the intercom, wired to the LED output on the gate controller, will give the necessary feedback about the status of the gate.



Courtesy (Pillar) light (LIGHT/LIGHT)

This feature is associated with the LIGHT connections on the controller.

The pillar light circuit has multiple functions:





It operates as a courtesy light and switches on for a preset timed period of two minutes every time the gate is activated

 Pillar Light Control (LIT): It can be turned on permanently by making a contact via a single pole, single throw switch connected between LIT and COM



Auxiliary wallbox card

An LED interface, which provides three inputs for switching LEDs, is included with the kit



A typical use would be to connect the controller’s status LED to the interface, and in so doing ensuring that you are always aware of your gate’s movements. It is also a handy notification system for power failures, multiple collisions, etc.

 In addition, there is an optional anti-tamper switch which can be connected to a third party alarm. Should the cover be lifted without first deactivating the alarm, the buzzer will sound warning residents that the device is being tampered with

 If a 12 V DC buzzer is used, it can be powered directly from the controller’s 12V output, eliminating the need for an additional power supply

 The external indicator is connected between LIT and COM

Pedestrian Opening input

. (A normally-open potential-free input).

Momentarily connecting this input to COM will cause the master gate to open to the pedestrian open position. For more information refer to the pedestrian feature under Section 13.

Holiday Lockout

. (This is a potential-free, latching input). For as long as a connection between this input and COM is maintained the controller will behave normally. But, when this connection to COM is broken all inputs are inhibited. For more information refer to the Holiday Lockout feature under

Section 14.

Trigger input

. (A normally-open potential-free input). Momentarily connecting this input to COM will cause the gate to open or close depending on the operating mode selected. For more information refer to the gate trigger feature under Section 14.

Free-exit input

. (A normally-open potential-free input). Momentarily connecting this input to COM will cause a gate which is closed, or closing, to open or re-open. If the gate is open, or opening, the signal has no effect other than to reset the Autoclose timer (if selected). Free-exit (FRX) never initiates a closing cycle. The only way to close a gate, if only the FRX input is used, is to activate the Autoclose feature on the controller.

Allow external activation of the Autoclose facility. (This is a potential-free, latching input). Using the switch to make a contact between this input and

COM, will cause the Autoclose feature to be switched on. Breaking the contact will disable the feature.

The dipswitch on the controller, which can also be used for enabling the Autoclose feature, must remain switched off in order for the external switch to operate.

Activates the P

illar Light output

. (This is a potential-free, latching input).

Using the switch to make a contact between this input and COM, will cause the

light

relay to energize. Breaking the contact will de-energise the relay.

External gate status indicator

. (A low current output signal.) An output terminal which provides a low current drive (approx. 4,5V DC, 20mA) to a

LED which can be used to indicate the gate status remotely. If more than three LEDs are required it is necessary to fit the CP78 Multi-LED driver card. For more details on the feedback about the status of the gate provided by the status LED refer to Section 16.

Closing edge safety input

. (A normally-open potential-free input). When this connection is made it will prevent the gate from closing if it is stationary, and will stop and reverse the gate if it is closing. This input has no effect if the gate is opening.

Open limit contact for master motor

. The contact must be normallyopen. The contact is wired between this point and common.

Closed limit contact for master motor

. The contact must be normallyopen. The contact is wired between this point and common. Not used if a closed mechanical endstop is used to stop the gate.

The contact is wired between this point and common.

Closed limit contact for slave motor

. The contact must be normallyopen. The contact is wired between this point and common. Not used if a closed mechanical endstop is used to stop the gate.

Auxiliary supply for external accessories such as radio receivers, safety beams, etc. This is a 24V DC supply, maximum current 1.5A.

Ignore the fact that the control card is marked 12V. The model

CP77/24V is modified for a 24V output.

SOL

15V/15V

Solenoid strike

. A solenoid strike lock can be connected between 24V and

SOL. Note that the maximum current draw allowed for the lock is 2A.

Should the solenoid lock exceed this current rating it is necessary to use an interposing relay. If fitting a magnetic lock an interposing relay must be fitted to facilitate a normally-closed contact to drive the lock.

Input from charger transformer for battery charger circuit. 28-32V AC mains, approximately 30V AC.

Ignore the fact that the control card is marked 15V. The model

CP77/24V is modified for a 30V AC input.
