6. MANUAL EQUALISATION
The charger can be put in equalise mode only during absorption and float periods. When
the charger is still in bulk mode, manual equalisation is not possible.
To enable equalisation, enter the setup-menu and press the "-" or "+" button until the text
StArt will blink on the menu. Press SELECT for 4 seconds to start equalisation: the text
StArt will stop blinking.
To return to the normal display mode, press SETUP during 2 seconds.
To terminate the equalisation mode prematurely, press the "-" or "+" button until the text
StArt appears on the menu. Press ENTER to terminate equalisation: the text StArt will start
blinking
To return to the normal display mode, press SETUP during 2 seconds.
Current and voltage limits are identical to the automatic equalise function (see section 4.3).
The equalise duration is however limited to max. 1h when triggered manually.

7. TROUBLESHOOTING

With the procedures below, most errors can be quickly identified. If an error cannot be
resolved, please refer to your Victron Energy supplier.
Error nr. Problem
on LCD
display
n. a. The LCD does not light up
(no backlight, no display)
n. a. The LCD does not light up
(backlight works, no display,
charger seems to work)
n. a. The charge controller does
not charge the battery
n. a. High temperature: the
thermometer icon blinks
Err 1 Battery temperature too high
0
(> 50 C)
Err 2 Battery voltage too high
(>76,8V)
Err 3 Suspected wrong connection
during power-up.

Cause / Solution
The internal power supply used for powering the converter and
the backlight is derived from either the solar-array or the battery.
If PV and battery voltage are both below 6V the LCD will not light
up.
This may be due to low ambient temperature.
If the ambient temperature is below -10
segments can become vague.
0 0
Below -20 C (-4 F) the LCD-segments can become invisible.
During charging the LCD-display will warm up, and the screen
will become visible.
The LCD-display indicates that the charge-current is 0 Amps.
Check the polarity of the solar-panels.
Check the battery breaker
Check if there is an error indication on the LCD
Check if the charger is set to "ON" in the menu.
This error will auto-reset after temperature has dropped.
Reduced output current due to high temperature.
Check the ambient temperature and check for obstructions near
the air inlet and outlet holes of the charger cabinet.
This error will auto-reset after temperature has dropped.
This error can also be due to a bad/corroded battery- pole to
which this sensor is screwed on to, or a faulty sensor.
If error persists and charging does not resume, replace sensor,
and power-up by entering and leaving the setup menu..
This error will auto-reset after the battery voltage has dropped.
This error can be due to other charging equipment connected to
the battery or a fault in the charge controller.
Check if the T-sense connector is properly connected to a remote
temperature sensor.
This error will auto-reset after proper connection.
