These values are only guidelines, the best is to read the user manual of the battery,
to find out the exact deep-discharge voltage.
Current monitoring
The current is monitored of all 16 switching-outputs. In case of a detected
overcurrent all outputs are switched off in order to protect them from damage.
Nevertheless, the outputs are not completely short circuit proof! Therefore you have
to avoid short circuits at the outputs!
If an overcurrent is detected, the additional sound „Sound at overcurrent“ is played (if
the slot is not empty) and the red LED on the sound module is also permanently
switched on.
