Description
function of relay 1:
= switched off
= switched on
= automatic generator connection
= automatic load disconnection, only
activated if external sources are present
= automatic connection / disconnection of
loads due to SOC1
= automatic connection / disconnection of
loads due to SOC2
= programmable timer 1
= programmable timer 1
= absorption phase is active
= generator is running
= ext. voltage and frequency in permissible
range
= ext. grid is connected
= error
= warmup
= operation
(= currently has no function)
(= currently has no function)
= battery room fan
= electrolyte pump
function of relay 2:
