Connecting the power to MagicSafe
8.4 Connecting the connection cables of the 9-pole plug
(central locking)
MagicSafe features a universal connection for central locking to enable standard
central locking and engine-powered retrofitted central locking to be connected to
the system.
Connecting to the central locking system
➤ Determine the switching function of the original central locking system.
You will require the circuit diagram for the central locking system to do so. You
can obtain this from your vehicle dealership.
If no original circuit diagrams are available, you will need to gauge the function
of the control cables which run from the control unit of the central locking to the
vehicle doors.
A
NOTICE!
Only connect MagicSafe using the control cables for the central locking
and not using other cables.
Connection to other cables than the control cables or the use of an incorrect circuit
plan can lead to a defect in the central locking system and the hand-held transmitter.
➤ Determine the activation time of the central locking system.
In some vehicles, for example Mercedes, an activation time of 0.7 sec. might not
be sufficient to completely activate the central locking system. If so, you will
need to set the control time using the software function 3 (Signal duration of the
door locking contacts) to 3 sec., see chapter "Software functions" on page 36.
➤ Connect MagicSafe in accordance with the appropriate circuit diagram:
• Vehicles without a servo motor in the driver's door (driver's door cannot be
locked and unlocked from the passenger's door) or with pressure vacuum central
locking without electrical control cable: fig. d, page 9
You will require an additional servo motor for this, type no. ML-11 for the driver's
door.
• Two cables switching from negative to +12 V: fig. e, page 9
• Two +12 V pulse control cables: fig. f, page 10
• Two negative pulse control cables: fig. g, page 10
• One open and negative pulse control cable: fig. h, page 11
• One +12 V and negative pulse control cable: fig. i, page 11
