Additional Features - Centurion D2 Turbo Installation Manual

27. Additional Features

27.1. Battery saver
In the event of a battery-low shutdown, only
the motor will stop drawing current – the
controller, infrared beams and any other
peripheral device will continue to flatten the
battery; however, at a much slower rate.
An optional low cut-out switch (product code
CP107) totally disconnects the battery and
protects it from being fully discharged and
potentially damaged.
Consult your gate automation specialist for
further details.
27.2 Solar power supply
A solar panel can be used to charge the
battery instead of the conventional charging
circuit. A 20W panel will provide enough
power for 20 daily operations of an average
gate (less if 12V DC security lights are
fitted).
You will need to fit a deep-cycle low-
maintenance battery (minimum 35Ah) in
order to provide sufficient backup capacity
during days of poor weather.
These are typical values for Southern Africa.
Contact your gate automation specialist for
details on what solar panel to select in your
area.
The mains fail buzzer can be silenced on the
D2 Turbo Low-Voltage by inserting a wire
link between Aux 12V and power input
terminal.
