3.6 Solar Charge Management
EC468 and EC469 PSU's incorporate a
built-in solar charge management feature,
which will control the input from a separate
solar panel and regulator. Depending on the
charge state of the batteries, the solar power
will be directed to the required battery, and
continuously monitored to ensure optimum
operation. For this system to operate
intelligently, the shutdown button should be left
switched on. If the shutdown button is turned
off then the solar panel will charge the vehicle
battery only.
3.7 System Status and
Configuration display
On the 468 & 469 PSU, the unit contains an
LCD display and two control buttons that allow
system information to be viewed or settings
changed.
Press the top yellow 'select' button to change
the item being viewed. Press the bottom red
'change' button to change the setting. Both
buttons work on a continuous loop, so if
you want to return to an item or setting keep
pressing the button until the required item is
reached. The EC468 and EC469 PSU's also
contain a status display unit that can be used
to view system information. Press the top
yellow 'select' button to change the item
being viewed.
3.8 Water System Operation
The control panel pump button operates
the internal (onboard) water pump. This pump
will draw water from the internal (onboard)
water tank.
The system also incorporates a separate
powered water inlet that can be used with an
external filler pump to fill the internal (onboard)
water tank.
The water tanks (fresh & waste, where fitted)
incorporate a level warning feature to warn the
user when the fresh water level drops below
25% or when the waste water level reaches
100%. If the water pump power is turned on
and the fresh water level drops to below 25%
a warning beep will be heard and the fresh
gauge empty LED will flash. To cancel the
warning, press the levels button.
If the water pump power is turned on and the
waste water level rises to full (100%) a warning
beep will be heard and the waste gauge full
LED will flash. To cancel the warning, press
the levels button. These warnings will not be
repeated unless the water pump power switch
is turned off and on again. This is to ensure the
warning does not become a nuisance.
3.9 Frost Protection
On vehicles fitted with water tank frost
protection, the control panel frost protect
switch can be used to turn the feature on
or off.
With protection on, the system monitors the
tank water temperature and water level and
will control the tank heaters accordingly. If the
fresh or waste water levels are less than 25%
the appropriate heater will be turned off to
prevent overheating or damage to the element.
There are two types of system employed, both
working in a very similar way. One system
uses heaters with built-in thermostats; the
other uses separate temperature probes in the
tank. Both types switch on at 4-5°C and off at
8-10°C
3.10 Electric Step Operation
On vehicles fitted with an electric step, this
is operated by a button near the entry door.
Press and release the button to move the step
in or out. One press of the button will move
the step out, a further press will move the step
in again. If the engine is started the step will
move in automatically, after a short warning
buzzer. If this operation fails due to an obstacle
a buzzer will sound continuously to warn that
the step is still out, and therefore requires your
attention.
3.11 Warnings and Alerts
If the vehicle engine is started whilst the
motorhome is connected to the 230v supply,
a warning beep will be heard. This is to warn
you to remove the 230v supply before driving
away.
When the vehicle engine is running both the
vehicle battery and the leisure battery LED's
will flash in unison to indicate that they are
connected together and are being charged by
the vehicle.
