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
EC449, 468 & 469
PSU, the unit contains an LCD display and two control buttons that allow
system information to be viewed.
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 (if fitted) or the external water inlet, depending on the
position of the manual supply selector valve.
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 (if fitted).
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.
