Factory Setting; Load Curve - Cristec CPS3 12V/80A Manuel D'utilisation

3.3.3. Factory setting

The charger's factory settings are:
Sealed type battery (lead sealed)
BOOST in ON position
The installer should set the selection wheel (RC1) (excluding input and off-load 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.

3.3.4. Load curve

BOOST in ON position
With this setting the CPS3 charger delivers a 3-state load curve IUoU: BOOST, Absorption, Floating.
Flat batterry
CPS3-3M-DED
Batterry only slightly flat
BOOST in OFF position
With this setting, the CPS3 charger produces a single-stage UI type
load curve. It generates a constant voltage, supplying the current
required by the battery(ies). Recharging time depends on the state of
the battery, being longer than when the boost is in the ON position.

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 (depending on setting). If the current falls
BOOST
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
current has reached 15% of the charger's rated
current. The voltage switches to the Floating value
and the rated current continues to drop.
