I have a dozen LOVATO N emergency lighting fittings on the managed facility (model: LVNC / 1 / SE / AT). Every year on the anniversary of putting the building into use, the LEDs of all luminaires begin to glow red. Currently, three years have passed, so the manufacturer's recommended battery replacement period (every 4 years) has not yet passed. I am asking for advice on how to bring the luminaires back to normal operation.
In HYBRYD I had a "battery failure", "monitoring system failure" (m-bus). I read about yours and I was intrigued by the "self-test" (optional). Were you looking for something about this? Maybe the "damn thing" demands an annual review? What / how do you clear this error?
Locate the 3-pin screw terminal block marked as A, B and the inverted T (i.e. the screen) on the emergency module. For a few seconds you need to short A with the screen with any wire. The module must have L, N and battery connected.
