The installer should set the selection wheel (RC1) (excluding input and output voltage) and possibly adjust
the output voltage with no load using potentiometer RV1 (use the appropriate tool to turn the screw of the
potentiometer), depending on:
-
the type of battery (contact the battery manufacturer if necessary)
-
the intended usage
-
the cross-section and length of the output cables
-
whether or not the boost function is required
For special batteries, call in a professional installer, who will make the specific settings in accordance with
the accumulator manufacturer's specifications and according to the specifics of the installation.
CRISTEC disclaims any liability in case of damage to batteries or ineffective recharging.

U Boost:
BOOST voltage (see table above)
U Floating:
Floating voltage (see table above: voltage with no BOOST)
T Boost:
BOOST maximum duration (see table above)
Boost phase:
starts up automatically when the charger is turned on if the battery is flat. The current is
then at maximum output.
Absorption phase: begins when the voltage has reached the maximum BOOST level. The current level
starts falling.
These two phases combined last a maximum of T
BOOST
(depending on setting). If the current falls below
15% of rated current, the floating phase automatically kicks in. Duration and current intensity depend on
how charged the battery is.
Floating phase:
starts after T
BOOST
or if output current has reached 15% of the charger's rated current.
The voltage switches to the Floating value and the rated current continues to drop.
