2.1.1 Emergency power supply
The emergency power supply of the M-SHEV product family
is ensured by two 12 V backup batteries. Only VdS approved
lead batteries are permitted.
Switching between mains and emergency operation is auto-
matic if necessary.
2.1.2 Regulating the I / U charge
Lead batteries are charged in accordance with the re-
quirements of EN 12101-10. The control system recognises if
a lead battery is missing or faulty (self-diagnosis) and gener-
ates an error signal on the SHEV-emergency button (yellow
LED) and the central interface (yellow LED).
2.1.3 Monitoring the monitor input for sequential
control (mains/emergency operation)
The charging device switches to emergency power supply
(monitoring function) in case of a mains failure, undervoltage
of the power supply or if the primary power supply fails.
