4.1. Preparing the charging cables for use in showrooms
To make it easier to position the device under the vehicle, the charging cables can be separated
by means of the decoupler. (See Figure 2)
Note: Separation may only be carried out once the device has been switched off and unplugged from
the mains!
Figure 2: Charging cable in the Smart Charger series
Note: The charging cables shown in Figure 2 are only used with SC300-14 and SC500-14. Charging
cables without a decoupler are used from an output power greater than or equal to the SC750-14.
1. Disconnect the device from the mains supply.
2. Disconnect the charging cable at the decoupler provided for this in the middle of the charging
cable.
3. Guide the loose charging cable with the decoupler onward and downward through the engine
compartment.
4. Connect the charging cable on the decoupler to the device.
5. Connect the charging clips to the charging points provided on the vehicle.
6. Insert the mains cable into a mains socket (100 ~ 240 V AC).
7. To signal that the device has started, LEDs 2–4 will illuminate in a running sequence.
8. Depending on any customer-specific delivery specifications, after being connected to the mains
supply or after a restart, the device will enter the last used operating mode when put into
active mode.
Note: Changing between the operating modes is not possible in Active mode!

4.2. Initial setup
Once the device has been connected to the mains supply, a chaser appears featuring the three
colors of the status LED (red, green, blue) and the three LEDs which display the state of charge
(green, yellow, yellow).
Depending on any customer-specific delivery specifications, after being connected to the mains
supply or after a restart, the device will enter the last used operating mode when put into active
mode. During initial commissioning, this is typically cable compensation mode. (see Section 5.1)
Cable compensation must be performed for the device to operate optimally. For this, both charging
clips must be shorted (see Figure 3). The measurement is signaled by a running sequence through
LEDs 2–4. After around 30 seconds, the process is complete and the device switches to “Standby”
mode. The calculated cable resistance is permanently stored in the device. This value can only be
overwritten by performing a new, full cable compensation.
If the cable compensation needs to be repeated, the measurement can be carried out again in ca-
ble compensation mode by pressing the START button.
Figure 3: Charging clips in a short circuit
Note:
With device types SC300-14 and
SC500-14, the clips must be clamped
together at right angles so that the two jaws
connected to the cables are positioned on
top of each other (see Figure 3). With
device types SC750-14 and larger, the
clips must be clamped straight into each
other. Here too, the jaws that are
connected to the charging cable must lie
on top of each other.
The clips must remain connected for the
entire process.
The device is ready for use following successful cable compensation.
Note: If the charging cable is changed, cable compensation must always be carried out. Even if the
cable is exchanged for a cable of the same type, cable compensation must be carried out (see Section
5.1).

5. Operating modes
The chargers are designed for the following usage scenarios, according to the operating mode
selected. If the device is connected to the mains, the device will enter the last selected active
operating mode when started.
Note: The charger has intelligent temperature regulation. If the device temperature exceeds a pre-defined
value, the device's output is reduced.
5.1. Cable compensation
Note: Depending on any customer-specific delivery specifications, the parameters described may differ
or some modes may not be available. If you have any questions regarding the parameterization of your
device, please contact Deutronic Elektronik GmbH or one of our worldwide service centers.
Cable compensation mode is used to measure or compensate the resistance value of the
connected charging cables. This is necessary in order to compensate the voltage drop over the
charging cables during battery charging. Cable compensation only starts if the corresponding
operating mode is selected and if a short-circuit is detected at the start of compensation. This is
done by directly clamping the current clips together. The whole process is described in Section 4.2.
Note: If the charging cable is changed, cable compensation must always be carried out. Even if the
cable is exchanged for a cable of the same type, cable compensation must be carried out.
5.2. Charging Pb LTC / Charging Li / LFP LTC
Note: Depending on any customer-specific delivery specifications, the parameters described may differ
or some modes may not be available. If you have any questions regarding the parameterization of your
device, please contact Deutronic Elektronik GmbH or one of our worldwide service centers.
The XX-LTC operating mode is used for long-term charging and monitoring of vehicles in the
showroom with lead (charging Pb LTC) and Li/LFP (charging Li LTC) starter batteries. In support
mode, the device supplies the vehicle's electric loads until it reaches its power limit and any charge
deficiencies in the vehicle battery are subsequently compensated. The charging process
is interrupted at calculated intervals. During these monitoring phases, the battery is analyzed and
the parameters for the next charging interval are calculated. A full charge is load-dependent and
therefore cannot be guaranteed.
If no battery is connected to the device, load detection is active. This is signaled by LED4 flashing.
If the device's charging clips are connected to a battery that has a voltage within the pre-defined
range (Pb: 10.0 V – 13.7 V; Li: 11.0 V – 13.7 V), the charging process is started after the switch-on
delay. Battery voltages outside the pre-defined ranges are either indicated as "Battery voltage
too low" (status LED flashes red) or "Battery full" (status LED continues to indicate the selected
mode, and the green LED2 also lights up). Once the charging cycle is complete, monitoring will
begin. The battery status is indicated during monitoring. The parameters of the subsequent
charging cycle are calculated according to the duration of a monitoring phase. A charging process
in progress is signaled by a running light sequence of LEDs 2-4.

5.3. Charging Pb / ChargingLi/LFP
Note: Depending on any customer-specific delivery specifications, the parameters described may differ
or some modes may not be available. If you have any questions regarding parameterization, please
contact Deutronic Elektronik GmbH or one of our worldwide service centers.
In this operating mode, it is possible to charge either a battery which is installed in the vehicle or
a "stand-alone" battery (lead-based battery or Li/ LFP battery, depending on the operating mode).
If the charging clips of the device are connected to battery voltage within a predefined range,
the charging process will be started after the switch-on delay. The customer is able to select the
switch-on voltage threshold. The exact voltage value can be found in the relevant
parameterization.
During the charging process, the battery terminals or charging points of the vehicle are supplied
with a defined voltage. If the current demand exceeds the maximum output current of the charging
device, it switches to current regulation.
If the output current falls below a defined threshold value during the charging process, the device
switches to "maintenance charging" mode. To reduce aging of the batteries, the batteries are fed
with a voltage below the charging voltage during maintenance charging mode. If the output current
exceeds a defined threshold value during the maintenance charging process, the device will switch
to recharge mode. The output voltage is again increased to the level of the charging voltage. If the
output current falls below a certain value during the maintenance charging process, the device will
signal “Battery full” and switch to monitoring mode. If the clip voltage falls below a set value during
monitoring, the charger will restart the charging process.
During the charging process, special safety timers will monitor the charge volume and charging
duration. If one of the relevant safety thresholds is reached, the device behaves according to its
parameterization.
Note: The behavior of the device when the safety threshold is reached depends on the customer-
specific parameterization. For example this may trigger a switch-off of the output current, limitation of
the charging voltage to the maintenance charging voltage or possibly even no reaction if the parameter
has been deactivated.

5.4. PowerUp
Warning! PowerUp must ONLY be used for Li/LFP batteries with a suitable battery management sys-
tem!
Note: Depending on any customer-specific delivery specifications, the parameters described may differ
or some modes may not be available. If you have any questions regarding the parameterization of your
device, please contact Deutronic Elektronik GmbH or one of our worldwide service centers.
With lithium-iron phosphate batteries, the battery management system may open a relay to protect
the battery in certain circumstances (e.g. deep discharging). With the help of the PowerUp func-
tion, the relay can be closed again to restore the functionality of the battery (provided that the in-
ternal battery electronics allow this).
Before the actual PowerUp function is started, the battery undergoes testing for around 30 sec-
onds. The "PowerUp" operating mode is signaled by the green flashing status LED. After a suc-
cessful PowerUp, the device switches to "Standby" mode.
The “PowerUp” process will be aborted if the clip voltage or output current falls below a certain
value. (See Section 6.2)
Note: During the PowerUp, all of the vehicle’s parallel consumers (ignition, dipped beam, etc.) must be
deactivated. If it is not possible to deactivate parallel consumers, the PowerUp should be carried out in
standalone mode (disconnect the battery from the vehicle).
When the green status LED and yellow LED4 are flashing, the device is in active load detection
mode. This happens if no battery is connected, or if the relay for the connected battery could not
be connected within the first minute due to deep discharging.

5.5. EPS (external power supply)
Note: Depending on any customer-specific delivery specifications, the parameters described may differ
or some modes may not be available. If you have any questions regarding the parameterization of your
device, please contact Deutronic Elektronik GmbH or one of our worldwide service centers.
Warning! Batteries may only be charged in "CHARGE XX" or "XX LTC” modes, as the parameters and
monitoring functions required for ensuring safe battery charging are only activated in these programs.
These monitoring functions are not active in “EPS” mode.
The “EPS” mode is used to provide power to vehicle electrical systems when the starter battery is
not connected. In other words, it takes care of the supply of power to vehicle consumers in support
mode up to the device's power limit. If no valid load is present, the device is in load detection
mode. In this case, LED4 will also start to flash yellow. If a suitable voltage or load is detected for
several seconds (switch-on delay), the device will start to supply voltage.
Note: Modern vehicles have a very low quiescent current - especially two-wheeled motor vehicles.
Some of these vehicles are equipped with a start button. This must be pressed multiple times within the
first 1-2 seconds during ignition until a running light appears involving LED2-LED4.
During the power supply process, special safety timers monitor the supply volume and supply
duration. If one of the relevant safety thresholds is reached, the device behaves according to its
parameterization.
Note: The behavior of the device when the safety threshold is reached depends on the customer-
specific parameterization. For example this may trigger a switch-off of the output current, or possibly
even no reaction if the parameter has been deactivated.
