ELECTRICS
To prevent over discharge, the EC500 system
incorporates a battery protect circuit that
warns the users and then disconnects the
batteries when they fall below set values.
3.4 Generator Usage
Caution should be used before connecting a
generator to your caravan or motorhome.
WARNING: Never start or stop the
generator while electrical loads are
connected and switched on. Start the
engine, let it stabilise and then connect
the electrical load. To stop the engine,
disconnect the electrical load and let
engine stabilise before switching off.
Whilst some generators use electronic
inverter technology, others use a more basic
principle to generate the 230V supply.
Preference should be to choose a generator
which produces a consistent sinusoidal wave
form with accurate voltage control.
The Reverse Polarity warning light on the
PSU may illuminate when using a Generator.
This is a normal side effect when using some
types of generator. Instead of connecting the
neutral conductor to earth, some generators
centre tap the earth connection making both
neutral and live conductors 110V above
earth. This 110V difference causes the neon
polarity indicator to illuminate.
In most cases it is safe to use a generator,
but please consult the generator handbook
for further information.
3.5 Solar Charge Management
The EC500 PSU incorporates a built-in solar
charge monitor which will measure and
display the current being generated by an
attached solar panel (when fitted). For this
display to work correctly the solar panel must
be connected via a suitable solar regulator to
the provided solar panel connection and not
connected direct to the battery.
3.6 Water System Operation - Optional
Tank Fill Feature
With the optional onboard water tank
installed the system may also include an
automatic tank fill/infill feature which
operates as follows:
3.6.1 One Shot Fill/Auto Change
With the water pump turned off and an empty
on-board tank and a full external tank (Aqua
Roll) the user will press tank fill button on the
control panel and turn tank fill on. The external
pump will turn on and fill the on-board tank from
the external tank (pump LED on control panel
flashes to indicate filling). When the on-board
tank is full the external pump will stop and tank
fill will automatically be turned off at the control
panel. If the external tank runs dry before the
on-board tank is full the system will turn the
external pump off after 5 minutes to protect the
pump from burn out.
The user would now go and refill the external
tank.
The user can now turn the main pump on (tap
button) and the internal pump will deliver water
to the taps. Once the on-board tank is empty
the relay will switch over to the external tank
and water will continue to be delivered until the
external tank is empty. The external pump will
not stop when the external tank is empty; the
user will need to turn the pump off when water
stops flowing.
If the user does not want to use the on-board
tank, instead of initially using the tank fill option
they can just turn the main pump on (tap button)
and the external pump will deliver water to the
taps.
Note: The tank fill option should not be turned
on when the main pump is turned on.
