Batteries (emergency opening)
Description
Ni Cd batteries, with 24V supply and 800 mAh power.
Main function
The main function of the batteries is to open the door and keep it in this position (open door) when the power fails. It will
stay open until the power returns in all working modes ( automatic, winter, exit, open door) except for “closed door” and
“manual mode”. The digital selector display will show an “Error 17”.
In the “closed door” mode, the door will remain in closed position even if power fails. In the manual mode, the battery
will not activate as the motor will not have power, so it will stay in manual mode.
Standby mode
When the power supply fails the batteries will give power to the control board and peripherals for one hour. After that,
the control board will pass to a “standby mode”, where external devices are not supplied and the control board goes into
“sleep” mode.
To wake up from “sleep” mode, it needs a signal from the open impulse ( KB) or close impulse ( KC). With both inputs
the batteries can be activated to open or close the door.
Open Impulse ( KB) / Close impulse ( KC)
As has been explained in “standby” mode, the doors can be operated without the power supply by batteries with both
inputs, “open impulse” KB and “close impulse” KC.
