3.1 Starting up
" Connect the plug for mains operation to the 230V power supply.
Mains indicator LED illuminates. The batteries are being charged.
Y The mains indicator LED also illuminates when the MP 22-T display pa-
nel (and hence the 12V supply of the living area) is switched off.
3.2 Switching on and off
" Briefly press the ”12V On/Off” button.
F The indicator LED illuminates.
F The 12V living area supply is switched on.
" Briefly press the ”12V On/Off” button again.
F The indicator LED goes out.
F The 12V living area supply is switched off.
Y If the MP 22-T display panel will not switch on, this is because:
F If, after pressing the ”12V On/Off” button, the ”11.0V” LED and symbol
”V” flash, the battery voltage of the living area battery is low. See sec-
tion 3.5.1.
F If, after pressing the ”12V On/Off” button, the indicator LED, the ”Li-
ving Area Battery” symbol and the alarm display flash three times,
battery isolation is enabled. This must first be stopped. See section
3.6.2.
The 12V supply of the living area is switched on/off via the ”12V On/Off” but-
ton. Exceptions:
F Heater
F Floor light/step
F Frost protection valve
F Other circuits are excluded if required
(see instruction manual of EBL ... electrobloc)
These consumers are still operable even when the 12V power supply is swit-
ched off.
Y The system must be switched on using the ”12V On/Off” button on the
display panel to first start up these consumers after the electrobloc has
been switched off by the battery isolator (see section 3.6.2) or by the bat-
tery monitor (see section 3.5.1), after a battery change or after connec-
tion of the living area battery after a long break.
