2.6 Operation while driving
The EC500 system is designed to shutdown
parts of the system whilst the engine is
running. This is to meet Electro Magnetic
Compatibility (EMC) regulations and to
ensure the safe operation of your
motorhome.
Please ensure the system shutdown switch
on the PSU is in the “on” (button in) position
before driving (see 2.2). This will ensure the
electronic system is active and will therefore
be able to control the charging process,
supply the refrigerator and monitor other
system circuits.
When fitted, designated 12v sockets, en-
route reading lights and en-route heating will
remain operational while the engine is
running.
If you hear a warning buzzer when the
engine is started, please see the control
panel display for details and also refer to
section 3.11.
3 System Technical Information
The following section provides further
technical information relating to the electrical
system.
3.1 System Configuration
There are a number of dealer configurable
features within the system. Your dealer will
discuss these options with you and make the
necessary adjustments as required. Should
you wish to review the possible options /
settings, further information can be sourced
from www.sargentltd.co.uk
3.2 Residual Current Device & Miniature
Circuit Breakers
The Residual Current Device (RCD) is
basically provided to protect the user from
lethal electric shock. The RCD will turn off
(trip) if the current flowing in the live
conductor does not fully return down the
neutral conductor, i.e. some current is
passing through a person down to earth or
through a faulty appliance.
To ensure the RCD is working correctly, the test
button should be operated each time the vehicle
is connected to the mains supply (see section
2.3)
The Miniature Circuit Breakers (MCB’s) operate
in a similar way to traditional fuses and are
provided to protect the wiring installation from
overload or short circuit. If an overload occurs
the MCB will switch off the supply. If this
occurs you should investigate the cause of the
fault before switching the MCB back on.
The following table shows the rating and circuit
allocation for the three MCB’s
