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

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
FIGURE 5. STANDARD MOUNTING CONFIGURATIONS
Inside 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.
FIGURE 9
page 16
5. Cover the drainage holes on the inside with
duct tape.

FIGURE 13
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.
FIGURE 14
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.

but not cause damage to persons or objects
in the path of the gate(s).
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.
FIGURE 41

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

15. Description of terminal functions
PED
SP1
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.
TRG
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.
SP2
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.
ACL
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.
LIT
Activates the Pillar 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.
LED
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.
IRB
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.
MLO
Open limit contact for master motor. The contact must be normallyopen. The contact is wired between this point and common.
MLC
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.
page 35
SLO
Open limit contact for slave motor. The contact must be normally-open.
The contact is wired between this point and common.
SLC
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.
12V
SOL
Ignore the fact that the control card is marked 12V. The model
CP77/24V is modified for a 24V output.
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.
15V/15V
LIGHT
Ignore the fact that the control card is marked 15V. The model
CP77/24V is modified for a 30V AC input.
Pillar light connection. These two terminals provide a normally-open
potential-free contact, which is generally used to switch on a Pillar Light
(Courtesy Light). This contact is fuse-protected – 5A. The contact is
activated for a period of two minutes each time the gate is operated. Using
the LIT input referred to above, the light contacts can be energized
independently of the operation of the gate.
The common termination point. All trigger signals, etc. have their return
COM/COM path to one of the COM terminals.
