3.3.3. Factory setting
The charger's factory settings are:
Sealed type battery (lead sealed)
BOOST activated
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 ofthe
potentiometer), depending on:
- the type ofbattery (contact the battery manufacturer ifnecessary)
- the intended usage
- the cross-section and length ofthe 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 ofthe installation.
CRISTEC disclaims any liability in case of damage to batteries or ineffective recharging.
3.3.4. Load curve
BOOST activated
With this setting the CPS3 charger delivers a 3-state load curve IUoU: BOOST, Absorption, Floating.
U Boost: BOOST voltage (see table above)
U Floating: Floating voltage (see table above)
T Boost: BOOST maximum duration (see table
above)
Boost phase: starts up automatically when the
charger is turned on ifthe 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). Ifthe current falls
below 15% ofrated 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 ifoutput
current has reached 15% ofthe charger's rated
current. The voltage switches to the Floating value
and the rated current continues to drop.
BOOST desactivated
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 activated.
