Mains Failure Detection; Battery Low Protection; Thermal Overload - Centsys D3 User Manual

If a gate status indicator (LED) has been fitted inside the house, an additional
confirmation of the functioning of the override is provided. The status LED will
stop flashing and remain ON when the Autoclose has been overridden.
Mains failure detection (D3/D5 only)
Although these systems will continue to operate in the event of a mains power failure
due to the built-in battery, it is important to register that there is a problem before the
battery is run flat.
The controller (CP80) monitors whether mains voltage (via the charger transformer)
is present. If not, the gate status LED, will flash twice every two seconds to indicate
mains loss.
Battery low protection (D3/D5 only)
The controller has circuitry that monitors the state of the battery. During a power
failure energy is drawn from the battery, but not replaced. To prevent the battery
running flat and being damaged, the protection circuitry shuts off the gate system
when the battery voltage drops below 10.6V.
NOTE: - LED WILL FLASH THREE TIMES
EVERY TWO SECONDS TO INDICATE
BATTERY VOLTAGE IS LOW
- D3/D5 OPERATOR PCB SHOWN
If the gate status
indicator has not been
fitted inside the house,
there is an equivalent LED
mounted on the controller
RED LED
marked "STATUS"
STATUS
Thermal overload (A10 only)
In the event of the A10 operator being used excessively and the duty cycle rating of
the unit exceeded, the unit will shut down due to thermal overload in order to protect
the system from abuse.
The unit cannot be re-operated until the unit has cooled. To provide indication to the
user that this is the cause of the fault the status LED will flash twice every two seconds.
