3.1.1 Battery management
The CX212x knob module comes with a battery management system, which
indicates the need for battery replacement by means of a visible and audio
signal, when the battery power reduces (capacity loss) during the final 1,000
operations of the battery (see chapter7.2.1 Battery Replacement).
Signaling happens in 3 phases:
The battery needs to be changed soon.
If an authorized key is held in front of the knob module, the locking access right is
issued. The engagement is accompanied by red flashing (5x) and 5 short acoustic
signals.
The battery needs to be changed.
If an authorized key is held in front of the knob module, the knob module first
flashes green for 5 seconds, then the knob module engages. The engagement is
accompanied by red flashing (5x) and 5 short acoustic signals.
The battery needs to be changed immediately.
If an authorized key is held in front of the knob module, no locking access right is
issued, but rather the knob module goes to the battery change position. In
addition, the knob module flashes red 5x and gives 5 short acoustic signals.
The access data, the events log, the settings of the knob module and the time are
stored on non-volatile memory and thus retained even when there is no power
supply, for example, when changing the battery or if the battery goes completely
flat. The time is written to the non-volatile memory once every 30 minutes. If the
power supply remains off, then the clock comes to a standstill after a few seconds
and starts running from the last stored value onwards after the power supply is
restored.
