Input side
of the converter:
The
operating range
of charging converter
must be
set
for the operating mode (control
connection, switching thresholds) and the mode of installation (cable lengths to the starter
battery). For converter protection a battery must be at converters input side.
Also refer to: "Function of the Power Control for Starter Battery and Generator", page 10.
A
.
Pure
voltage control
of the charging converter, without separate control signal "Kl.15 / D+":
Because of the high voltage thresholds, only to be used with separately laid "Sense In +" line,
sufficiently dimensioned cable cross-sections and powerful generator.
The starter battery will not be discharged under any circumstances.
Control connection "Kl.15 / D+" must be connected to "Sense In" via a
wire jumper
!
Increase of the charging capacity:
> 13.60 V (27.2 V)
Reduction of the charging capacity:
< 13,20 V (26.4 V)
Switching off threshold charging converter:
< 12.60 V (25.2 V)
30 sec.
B
.
Slight load on the starter battery:
Only use these voltage thresholds with separately laid "Sense In +" line, sufficiently dimensioned
cable cross-sections and powerful generator.
Note: A continuous signal at "Kl.15 / D+" without running motor might discharge the starter battery!
Increase of the charging capacity:
> 13.20 V
(26.4 V)
Reduction of the charging capacity:
< 12.80 V
(25.6 V)
Switching off threshold charging converter:
< 12.20 V (24.4 V)
30 sec.
C
.
Without sense line "Sense In +" of the starter battery:
If the cross-sections of the cables to the starter battery are sufficiently dimensioned, a separately
laid line "Sense In+" is not required. A
wire jumper
must be laid from "IN +" to "Sense In +"!
Note: A continuous signal at "Kl.15 / D+" without running motor might discharge the starter battery!
Increase of the charging capacity:
> 13.40 V
(26.8 V)
Reduction of the charging capacity:
< 12.80 V
(25.6 V)
Switching off threshold charging converter:
< 12.20 V (24.4 V)

Vehicles according to
EURO Standard 6
, 6+ and for
parallel operation
of 2 charging converters:
If the cable to the starter battery is short (<2 m) and the cable cross-section is sufficiently
dimensioned, a separately laid voltage sensor line "Sense In+“ is not required. However, in this case a
wire jumper
is required for connection of "Sense In+" to "IN+".
This switch position is also provided for
EURO standard 6, 6+ vehicles
with energy management,
start/stop automatics, strongly varying voltage of generator/starter battery during energy recovery
etc.). If the cables are very long (losses), a separate voltage sensor line from the + starter battery to
"Sense In+" might be advantageous.
Always use the control input "D+ / Kl.15", and either connect it to KL.15 (ignition ON) or
more safely
to
D+
of the vehicle (generator is "active"), since in case of a continuous signal without running
motor the starter battery can be
strongly
discharged!
Increase of the charging capacity:
>
11.70 V
(26.0 V)
Reduction of the charging capacity:
>
11.40 V
(24.8 V)
Switching off threshold charging converter:
<
11.20 V
(23.6 V)
30 sec.
Option:
Parallel Connection of 2 Charging Converters:
An increase of the charging capacity for large battery systems or high loads (such as operation of an air-conditioning
system) can be realized by parallel connection of two identical units. Couple the connections and set
both units
to
switch position
"D"
according to table 2.
A separately laid voltage sensor line from starter b (plus) is then to be distributed to the "Sense In +"
inputs of the units, particularly for
Euro Standard 6
vehicles.
Due to the occurring high current rates, the required
cable cross-sections
must be multiplied by two, or they
must be
observed
absolutely in case of separate laying.
