Led Indicators; Connections And Controls - Dometic BUTTNER MT150PP Montage- Und Bedienungsanleitung

• Measurement output for electroblock (EBL):
Enables showing the charging current of the
house battery on the vehicle's electroblock
when equipped with DT/LT display panels
• Terminal "AES/RE" (only MT 350 PP,
MT 550 PP): Transfers excess solar power to
small loads or automatic energy selector (AES)
capable refrigerators
• Output for remote displays LED I or LCD II
The solar charger has the following protective
mechanisms:
• High voltage and low voltage protection
• Deep discharge and overcharge protection
• High temperature protection
• Low temperature protection
• Protection against short circuit
• Protection against reverse polarity connected
solar modules and loads
• Reverse polarity protection for the house battery
• Battery overcharge protection
• Reverse current protection
• Built-in temperature controlled cooling fan (only
MT 350 PP, MT 550 PP)
The solar charger can be adapted to different bat-
tery types via DIP switches (chapter "Setting the
charging program" on page 15).
The temperature sensor monitors the battery tem-
perature during the charging process to control
and adjust the charging voltage accordingly (chap-
ter "Temperature sensor" on page 12).
