SLIDING GATE OPERATOR
Introduction The Nice 24 Sliding Gate Controller was designed to take advantage of
the superior torque and power of the 24 Volt motor. Conceived as a Dual Supply”
system, the operator runs efficiently on the 220Volt Mains supply under normal
conditions, and, changing over seamlessly, continues to run from the on-board
batteries during a power failure. A switch mode power supply is used to convert the
mains to the 24 Volt power for the motor, the controller and accessories, and the
charging circuit, which ensures that the batteries are fully charged at the correct
voltage for long life.
Performance Using micro-processor control to provide ramp-up and ramp-down
speed control, the Nice 24 starts smoothly, accelerates quickly to full speed (16,7metres
per minute, one of the fastest operators available), slows down in the last half metre of
travel and stops firmly and gently under electronic braking.
Designed to operate without limit switches for ease of installation, the unit learns” the
full extent of the gates travel by physically sensing the rail-stops, and then automatically
leaves a small safety gap at each end during normal operation, eliminating noisy
knocking.
Features
Easy Programming An on-board display makes it easy to select and enter the required
features, which include Learning Limits, Auto-close (none, 5, 10 or 20 seconds), Safety
beam selection, Obstacle Sensing Level, Recording Remote controls (up to 16), and
Type of operation, which may be ‘Standard’ (Residential) or ‘Commercial’.
On-board Radio Receiver The controller has a Digitronic e-Key receiver on board that
provides state-of-the-art secure access control using Keeloq code-hopping technology.
The receiver stores up to 16 transmitters in non-volatile memory.
Optional external Lamp External 220V lamps may be connected to the controller,
which will come on with every gate operation, and time-out 3 minutes later. These
lamps may turned or off by means of a connection to the intercom. The combined
power of these lamps is restricted to 250W.
Easy Installation Connections to the controller are made by means of plug-able
terminal blocks, simplifying installation and maintenance. These connections include
the intercom connection, partial opening for pedestrians, lock, safety beam, etc.
The configuration of the machine and the transmitter are stored in a plug-able memory
chip, which can be easily transferred to a replacement controller, making re-
programming un-necessary.
Installation Install the operator according to the enclosed instructions.
Important! For safety reasons, the gate must have physical end-stops in both the closed
and open positions. A sturdy rail-stop must be securely fitted to the track of the sliding
gate in the fully open position. In the closed position, the gate normally stops against the
gatepost. If not, a sturdy rail-stop must be securely fitted in the closed position as well.

2
Height ad ustment For the height adjustment to be possible, the four adjusting screws
provided in the small accessory box must be fitted as in fig. 9 on page 7, before
mounting the machine to the steel base plate. Ideally, these screws should protrude 5 to
10 mm, creating a gap between the base plate and the under side of the machine. This
will allow for subsequent height adjustment.
Wiring For all connections refer to Fig. 1.
Mains. A suitable cable (armoured 3-core or Surfex) should be used from a 2-amp
circuit breaker on the distribution board to the site of the motor, where it is
brought up through the opening in the base plate. See page 5 Fig. 4. Connect
the earth wire and the armour to the spare lug provided on the chassis earthing
point. Connect the Line and Neutral wires to the terminals ‘L’ and ‘N’ on the
controller, shown as ‘230V MAINS’ in Fig. 1.

Accessories.
Before connecting any accessories, decide which ‘Type’ of operating mode will be
used, ‘Standard’ or ‘Commercial’. ‘Standard’ is suitable for residential purposes, giving
each user full control of the gate. ‘Commercial’ avoids conflicting inputs by providing a
dedicated ‘Open’ input for the users. Separate ‘Stop’ and ‘Close’ connections are also
provided.
Note: All the accessories are referenced to ‘0V-COM’.
N.C. and N.O. refer to switch contacts, and stand for ‘Normally Closed’ and
‘Normally Open’.
Partial. For pedestrian use, a key Switch may be connected to ‘Partial’.
This switch will cause the gate to open to a width of about 1,2m. Once partially opened,
the gate may be re-closed using the same switch, or it will auto-close in the time
selected (5, 10 or 20 seconds) or in 5 seconds if Auto-close is not selected.
If the gate is closing after being partially opened and the safety beam is blocked, the
gate will only re-open to the partially open point.

3
Control. The wire for control from the intercom (or other devices for opening, ground
loops, card readers, keypads, etc.) is connected to ‘Control’ or ‘Open’ depending on
the ‘type’ chosen.
Lock. An optional switch (e.g. fitted to the intercom) may be connected this input.
When active, the gate cannot be operated, even by a valid control.
Using this input once the gate is open will disable Auto-close until the Lock switch is
released. In Commercial mode this input serves as a ‘Stop’ command.
Light On/Off. If an optional external lamp or lamps have been connected to ‘LAMP, N, L’
as in Fig. 1, these may be controlled by a push-button connected to this input. If off, they
will be turned on or off if they were on. The combined power of these lamps is restricted
to 250W.
In Commercial mode this input serves as a ‘Close’ command.
Safety Beam. If a Safety Beam is fitted, it is connected to ‘0V-COM’, Beam N.C.’ and
‘Beam 24V+’. If the Safety Beam is blocked whilst the gate is closing, it will automatically
stop, pause and re-open. The Safety Beam has no effect during opening of the gate. An
active Safety Beam will prevent the gate from Auto-closing, or being deliberately
closed.
Position the Safety Beam low enough to protect toddlers and pets, yet high enough so
that the under-side of most cars will not clear the beam. Be aware that high-bed trailers
or trucks may not block the beam, and care must be taken while they are in the
gateway.
If, during the course of the day, direct sunlight at a low angle falls on one side of the
gateway, it is advisable to fit the transmitter of the Safety Beam units to that side.
The installation of Safety Beams is strongly recommended, especially if Auto-close is to
be used. If Auto-close is selected and Safety Beams are not fitted, the gate will not
operate, unless a wire link is fitted from ‘0V-COM’ to ‘Beam N.C.’. This is, however, not
advised.
Gate Status. An LED fitted to the intercom in the house and connected to ‘Gate Status
LED+’, will indicate the status of the gate by illuminating when the gate is not closed,
and flashing while the gate is running. This signal may also be used to drive an audible
device such as a buzzer, with interfacing suitable to the device.
On-board Radio Receiver. The Radio Receiver on-board will support up to 16 Digitronic
eKey Remote controls. The recording of these uniquely coded Remotes is simple, as is
the removal of the codes. These codes are stored in a plug-able memory chip, together
with the controller configuration, limit positions etc., and may be swapped onto a
replacement control board for maintenance purposes.
If an off-board Receiver is to be used, connect it to ‘BATTERY’ + and –, and the N.O.
output to ‘CONTROL/OPEN’. The On-board Radio Receiver should be disabled as
follows:
Isolate the power by switching off the mains 220 volt supply, and removing the
wire link between the batteries.
Remove the clear protective cover (held by a screw at the top) and the control
board (held by a screw at the bottom).
Locate the link on the left side on the back of the board.
Using a small drill-bit, remove the small circle pad between the two square pads.
Initial Power-up
Once the motor, the rack and the Rail-stops have been installed, proceed as follows:
1. Put the machine in ‘Manual’ by unlocking and pulling the Manual Over-ride
Lever, and position the gate mid-way.
2. Connect the batteries with the white jumper lead, and switch on the mains.

4
3. Engage the Manual Over-ride Lever. The display will flash ‘S C’ and the motor will
start running slowly.
4. Check that the gate is closing, in which case skip to 6. If not, go to step 5.
5. Pull the Manual Over-ride Lever. Referring to Fig.1, swap the Motor wires on the
second plug. Re-engage the Manual Over-ride Lever and the motor will close.
6. On reaching the closed position, the operator will detect the rail-stop and halt.
The display will show C” for closed.
If the gate has stopped short of the fully closed position, this is an indication of the
amount of power required by the gate, considering all the related factors.
The power setting and Obstacle Sensing are directly related, and should be increased
incrementally and re-tried until the gate reaches the closed position on the lowest
possible obstacle setting. If, on the highest setting of 3, the gate still fails to close fully,
then the gate is possibly too heavy (greater than 400 Kg), or there is too much rolling
resistance due to the condition of the track, the size of the wheels related to the weight
of the gate, or the state of the wheel bearings and guide rollers. Also check that the
rack is engaging smoothly with the gear, showing the correct clearance over the full
length of travel.

Normal Operation
Standard (Residential) Type
Assuming the gate is closed, when the controller receives a command from a
remote control, the gate will start opening, ramp up to full speed, and ramp down to
stop in the fully open position.
The gate may now be closed using the remote control, or it may be left to Auto-
close, if selected. The gate will close, ramping up and ramping down to stop in the
closed position.
Whilst the gate is opening or closing, a further command will cause it to stop.
If the gate is obstructed while closing, the gate will stop, reopen at slow speed and
bump the open rail-stop to re-calibrate itself.
If the gate is obstructed while opening, the gate will simply stop. When the gate next
closes, it will do so at slow speed and bump the closed rail-stop to re-calibrate itself.
Commercial Type
If selected as a Commercial Type, the controller regards all signals from remote
controls as dedicated ‘Open’ commands, thus avoiding the conflict that arises in a
multi-user situation.
If required, separate buttons for Open, Stop and Close may be installed, for instance,
in a guard-room.
Manual Over-ride
If it should be necessary to use the gate manually, slide the key-cover open, unlock
and pull the Manual over-ride lever. The gate may now be operated manually.
When the Manual over-ride lever is re-engaged, the motor will immediately start
closing the gate at slow speed to re-establish the closed position. Normal operation
will then continue.
