The PS224 buffer battery (Fig.1) may only be installed in gate
automation systems equipped with NICE control units. The battery
enables the storage of energy while the automation is powered by
the electrical mains, energy that is returned to the system in the
event of a power failure (buffer operation); approximately ten
manoeuvres can be performed in the absence of mains power.
Depending on the type of automation with battery function, the
manoeuvre speed can be slower than that with the mains power
supply.
Warnings
• The installation, testing and set-up of automation devices for doors
and gates must be performed by qualified and experienced personnel
who must also determine the type of tests required based on the risks
involved, and ensure that laws, standards and regulations in force are
complied with.
• NICE disclaims responsibility for any damage resulting from improper
use of the product; the only use authorized by the manufacturer is the
one described in this manual.
• The packaging materials must be disposed of in compliance with the
regulations locally in force.
• The buffer battery must not be immersed in water or any other liquid sub-
stances. If liquid substances should penetrate inside the device, discon-
nect it from the automation system immediately and call NICE customer
service; using the device under these conditions could be hazardous.
• Do not place the buffer battery near heat sources or expose it to open
flames; this could damage the device and cause malfunctions, fire
hazards or other dangers.
• In case of prolonged inactivity, to avoid the possibility that harmful sub-
stances may leak from the buffer battery, the latter should be discon-
nected from the automation system and stored in a dry location.
1) Description and Intended Use
2) Installation
The power supply to the system must be disconnected
during installation of the PS224 buffer battery.
The connection cable between the PS224 and the con-
trol unit has no poles and can be introduced from either of
the two sides; whereas the connectors are polarized and
must be introduced respecting the direction indicated by
the connection teeth.
For installation of the PS224 buffer battery, refer to the instructions
shown on the automation device.

3) Operational Checks and Testing
The following tests should be carried out immediately after connect-
ing the battery to the control unit.
• Make sure that the “L2” LED (Fig.1) is on, showing that the battery
is supplying energy to the system. Make sure that the different
LEDs on the control unit signal that the latter is operating properly.
• If these things do not occur it probably means that the battery is
completely exhausted; in this case proceed to the next step and
wait a few hours with the automation system powered by the
mains before you test the operation of the battery again.
• Connect the automation system to the mains power supply and
see whether the “L1” LED (Fig.1) lights up to signal that the battery
is recharging correctly.
• Activate at least one opening and closing manoeuvre to make sure
that the system operates properly when it is powered by the elec-
trical mains.
• Disconnect the automation system from the electrical mains; make
sure that the “L2” LED (Fig.1) lights up, then activate at least one
opening and closing manoeuvre to make sure that the system
operates properly also when it is powered by the battery.
Note: depending on the type of automation with battery function, the
manoeuvre speed can be slower than that with the mains power
supply.
• At the end of the tests, reconnect the automation to the electrical
mains.
