5. Additional Features
5.1. Battery saver
In the event of a Battery-low
shutdown, only the motor will
stop drawing current - the
controller, photocells and any
other peripheral device will
continue to flatten the battery;
however, at a much slower rate.
An optional Battery-low cut-out
switch (product code CP107)
totally disconnects the battery
and protects it from being fully
discharged and potentially
damaged.

5.2. 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
(less if 12V DC security lights are
fitted) of an average gate*.
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 Centurion Systems (Pty) Ltd or 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.
