[1] CYCLIC STORAGE - NOTE:
If during a charge process the voltage supply of the charger is interrupted,
then the battery charging is continued automatically at setting STORAGE
CYCLIC as soon as the mains supply is back again (all meter readings, e.g.
previous ampere hours, are further updated).
[2] MAN. STOP – SAFETY NOTE:
ATTENTION! The protective safety shut-down of the charger at the safety
limit (Ah-limit, maximum charging time) is deactivated at MAN. STOP.
[3] MAXIMUM VOLTAGE U
MAX
– SAFETY NOTE:
ATTENTION! The limiting value for maximum voltage 15.5V is an OVP
SAFETY LIMITATION for protecting the electrical system of the motor vehicle
from harmful overvoltage! The 15.5 V safety threshold limits on the one hand
higher parameterized charge and supply output voltage values and on the
other hand the safety threshold limits when an active cable compensation in
process would cause an output voltage over the limit.
Note: The safety threshold can be deactivated (e.g. when a huge voltage
drop on the cable clamps occurs and through cable compensation 15.5 V are
needed). Information: For controlling the output voltage the main screen (see
5.3) shows the actual voltage at any time.
[4] SAFETY U
SRT
– SAFETY NOTE:
The charger is able to recognize a short circuit automatically and is thereby
able to charge the output current down if a prescribed voltage wave (short
circuit voltage U
srt
) was fallen short of in the operating state on the output of
the device. The short circuit voltage – parameterised in the menu has to be
checked in consideration of a voltage drop relating to the connected charging
cables. The voltage has to be adjusted to the resistance of cable clamps and
max. output current of the device in case of need! Attention: Cable clamps
perish in operation due to this their resistance increases. Therefore, please
include a wide safety margin for short circuit nominal voltage!
Example of determining the short circuit nominal voltage ‚U
SRT
‘:
a) In the course of implementation of the cable compensation [7] a resistance value of 15
mOhm was determined for the connected charging cable.
b) The maximum output current of the charger is 100A.
c) Calculation of the voltage drop ∆U = 0.015 Ohm * 100A = 1.5V
d) Definition of short circuit voltage: The short circuit voltage has to be configured with a
proper distance from the calculated voltage drop for a safe switch-off (because of the
aging process of the cable, contamination mechanical tongs in operating state or
enhanced contact resistance at contact points).
For the present case a value of 5.0V can be configured.

[5] SECURITY LIMITING - OVERLOAD OR SHORT CIRCUIT BEHAVIOUR
If the voltage at the measuring point on the device output drops below U
srt
the
output current will be limited and the output relay will open.
[6] SECURITY PULSING - OVERLOAD OR SHORT CIRCUIT BEHAVIOUR
The output relay will open for 60 seconds if the output voltage drops below
U
srt.
After that time period a new switch-on will be attempted for proofing if the
load can be supplied or the short circuit (or situation of overload) is still
present. In total, the DBL emits three pulses – in case the overload or the
short circuit is still present no more attempts are made until disconnection of
the load or reset of the device.
[7] CABLE - REFERENCE TO THE CABLE COMPENSATION:
Before the cable compensation can be started first select STOP in the main
menu!
To perform the cable compensation the charging cables have to be
connected with the device and furthermore the charging cables have to be
shorted on the free ends (without load) with direct contact at the current-
carrying clamp shoe.
In order to perform the resistance measurement please navigate to the
DEVICE MENU / CABLE, select START item and press the ENTER button -
the cable compensation is now running for about 30 seconds. If the cable
compensation has been performed successfully the measured resistance
value will be shown on the display. The resistance value can also be entered
or changed manually by selecting line “R:” and activating edit function with
ENTER button. The value can be modified with the arrow buttons and finally
selected with the ENTER button.
The measured or configured resistance value is stored and is retained even
after the unit has been switched off.
Please note:
- Depending on the customized terms of delivery the factory-setting regarding
the cable compensation can differ from 0 Ohm!
- If a cable resistance value is disposed the DBL automatically activates the
dynamic short circuit detection (in addition to the U
srt
configuration).
The dynamic short circuit detection function considers R
cable
as well as the
configured I
max
from the selected operation mode and will be activated as
soon as the calculated U
srt-dynamic
> U
srt
.
