12V POWER SYSTEM

Note: The connection of the battery charger
to the mains supply is in accordance with the
Regulations for Electrical Installations 16th
Edition (IEE Wiring Regulations) BS 7671:
1992.
The Power System is supplied fitted remotely
in a convenient position and comprises:
(a) Mains Unit
(b) Transformer/Charger Unit

TRANSFORMER/CHARGER UNIT

The transformer/charger unit has important
safety features:
• Overload protection
• Short circuit protection
• Reverse battery polarity protection
The unit has been designed not only to
operate as a battery charger, but also for use
as a power supply, should a 12V DC battery
not be present in circuit. It is, however,
recommended that a good quality leisure
battery is installed.
Once connected to a 230V mains supply and
switched on, its operation is fully automatic.
To charge either battery, position the battery
selector switch to the appropriate position on
the distribution panel.

Charger/Transformer Charger/Transformer
When used as an alternative DC power
supply, with no battery in circuit, the will
supply a suitable output for use with pump,
lighting, T.V., radio etc. Should the unit
become overloaded the 12A DC fuse will
blow. Removal of the overload or fault allows
the unit to return to normal operation, after
replacing the DC fuse. A 1A anti-surge AC
fuse is provided as further protection.
Under normal circumstances the total load
required by motorhome equipment should
not produce an overload situation.
The facility for drawing 12V supply from the
cab battery is intended for standby situations
only, and care should be taken not to run the
cab battery too low, some models feature
cab battery protection circuitry.
If the cab battery has been used on site, then
the engine driven alternator will recharge
both it and the caravan battery whilst
travelling.
However, once the cab battery is fully
charged, the alternator will supply a trickle
charge only to the caravan battery.
This will take place regardless of the position
of the battery selector switch on the
distribution panel.
1. INTRODUCING THE EC200
ELECTRONIC CONTROL SYSTEM
With the use of new technology and an
innovative approach to user interfacing, the
EC200 Power Control System provides a
complete control solution for a wide range of
leisure vehicles.
The microprocessor controlled digital system
allows the user to control equipment and
view / edit system information from a user-
friendly control panel that incorporates a
liquid crystal 'ALPHA-NUMERIC' display.
The built in 'intelligence' prevents over
discharge of the vehicle battery, allows
greater control of the water system and has a
built in alarm clock. With the addition of an
