The desired function can be activated with an impulse of min. 20ms/24V.
If a FT or BT should be made once again the Function-Duration test must be reset by an impulse.

These subassemblies allow the connection of the central battery system to a central control station (ZLT) or building
management system (BMS). The most important system states are transmitted via potential-free signalling contacts.
There are two input channels for the remote monitoring of the central battery system. A functional test can be initiated
via the input channel „FT“ and a continuous operation test (battery test) can be initiated via the input channel „BT“. Eight
LEDs indicate the state of the system.
