How to set the
operating mode
of the starter battery (IN, input side)
The automatic control (activation) of the charging converter after the engine start can be executed in two different ways:
In case of special applications, voltage-controlled by the increased voltage of the starter battery with running engine
(not for EURO 6 vehicles!)
Recommended with vehicle "D+" signal (generator active, recommended) or with ignition on (vehicle terminal 15).
Table 4:
Selector
Switch
IN Input Side
of the Charging Converter:
Set the operating range and the behaviour of the charging converter up to the starter
circuit. Also refer to
"Function of the Power Control at Starter Battery and Generator", page 17.
1.
Pure
voltage control
of the charging converter, leave terminal "D+" blank:
Because of the high voltage thresholds, only to be used with "
Vs-
and
Vs+
" start sensor cables,
sufficiently dimensioned cable cross-sections and powerful generator.
The starter battery will not be discharged under any circumstances.
Increase of the charging capacity:
> 13.50 V
Reduction of the charging capacity:
< 13.20 V
Switching off threshold:
< 13.00 V 30 sec.
2.
Pure
voltage control
of the charging converter, leave terminal "D+" blank:
Like
1.
However, lower switching thresholds, negligible load of the starter battery.
Increase of the charging capacity:
> 13.30 V
Reduction of the charging capacity:
< 13.00 V
Switching off threshold:
< 12.80 V 30 sec.
3.
Activation of the Charging Converter by
Control Signal
"D+" or ignition "Kl.15".
Because of the average-high voltage thresholds, only to be used with "
Vs-
and
Vs+
" starter sensor
cables, sufficiently dimensioned cable cross-sections and powerful generator.
Note: A continuous signal at "D+" without running engine might discharge the starter battery!
Increase of the charging capacity:
> 12.50 V
Reduction of the charging capacity:
< 12.20 V
Switching off threshold:
< 12.00 V 30 sec.
4.
Activation of the Charging Converter by
Control Signal "D+"
or ignition "Kl.15".
This operating mode is particularly provided for
EURO standard 6, 6+ vehicles
with intelligent
generators, energy management, start/stop automatics, strongly varying voltage of
generator/starter battery during energy recovery etc.
Generally recommended for operation with electroblock
EBL
, EVS.
The start sensor cables "
Vs-
and
Vs+
" are not required, if the values in the
tables 1
for "
Cable
Length "+ START"
are only used to approx. 3/4.
If the cables are long (losses), these cables are, however, advantageous for full charging capacity.
Control the control input "D+" either with KL.15 (ignition ON) or
more safely
connect it to
D+
of
the vehicle (generator "active"), since in case of a continuous signal (ignition ON) without running
engine the starter battery can be
strongly
discharged!
Increase of the charging capacity:
>
11.70 V
Reduction of the charging capacity:
<
11.40 V
Switching off threshold:
<
11.20 V
30 sec.
Option:
Parallel Connection of Two Charging Converters:
An increase of the charging capacity for large battery systems or high loads (such as operation of an air-conditioning system
with low capacity units) can be realized by parallel connection of two identical units. Couple the connections and set
both
units
to switch position
"4"
according to table 4.
The separately laid "
Vs-
and
Vs+
" start sensor cables are to be distributed to the inputs of both units, also the
"D+" control signal.
Due to the occurring high current rates, the required
cable cross-sections
of the power supply connections
must be multiplied by two, or they must be
observed (tables 1)
absolutely in case of separate laying.
