All-automatic dual charger with 2 completely independent battery circuits for ambulance cars,
intervention vehicles and special purpose vehicles.
If not connected to the battery the units will not supply any voltage (protection against
reverse battery, safety relay, minimum battery voltage 1.0 V)!
Please read the mounting instructions and operating manual including the safety
regulations completely prior to starting connection and start-up.
The description is identical for both chargers.
VOTRONIC dual chargers of series “VAC DUO” distinguish by their compact design, low weight (high-frequency
switching power supply, Switch Mode Technology), as well as full charging capacity - even in case of large
deviations in the power supply (low voltage/overvoltage, sine curve, frequency).
The intelligent microprocessor charging control with characteristic lines of charging „IU1oU2“ and dynamic
charging time calculation ensures automatic, quick and gentle full charging, as well as subsequent 100 % trickle
charge of the connected batteries from any initial charging state. At the same time, simultaneous supply of 12 V
consumers, which are connected in parallel, is ensured or charging of very large batteries (depending on case of
application).
Operating Instructions:
All-automatic Continuous Operation: The charger may be connected continuously to the batteries, thus
keeping the full charge. Battery discharge in case of power failure is avoided (integrated safety relays).
The charging voltage being free from peaks is controlled in such a way, that any overcharging of the batteries
is excluded.
Parallel and Floating Operation: In case of simultaneous current consumption by consumers, charging of the
battery is continued or the charge will be conserved fully. Calculation and control of the adaptation of the
charging time is effected automatically by the charger. Sensitive consumers are protected by overvoltage
protection at any charging state.
Unattended Charging: Multiple protection against overload, overheating, overvoltage, short circuit, reverse
battery, excess temperature of the battery, incorrect behaviour and back discharge of battery by electronically
controlled gradual reduction down to complete separation of charger and battery by integrated safety relays.
Temperature Compensation: Automatic adaptation of the characteristic line of charging to the battery
temperature.
Integrated On-board Mains Suppression Filter: Unproblematic parallel operation of solar systems, dynamos,
generators etc.
Charging Cable Compensation: Automatic compensation of voltage losses on the charging cables.
Measurement of the voltage is to be effected at the battery and never at the charger (losses at the charging
cable).
Battery regeneration in case of extended stop periods: twice a week to avoid harmful acid accumulation.
Port +86 for motor lock while the vehicle is still connected to mains
Interruption or restart of the charging process: Due to power failure or unit switch OFF.
In case of frequent interruptions, particularly before reaching the full charge ("Battery Full" is lighting
permanently), a complete charging cycle of 24 hours of the battery should be executed more often
(compensation charging).

Lifetime of the battery:
Keep batteries cool; choose an appropriate location for installation.
Open acid batteries („maintenance-free according to EN / DIN“): Check the acid level
periodically!
Batteries being totally discharged should be recharged immediately, partially discharged
batteries should be recharged fully as soon as possible to avoid sulphation!
Store only fully charged batteries and recharge them periodically, particularly in case of older,
used batteries and in case of higher temperatures! If the grade of sulphation is not too intensive,
the battery can recover part of the battery capacity after several charging/discharging cycles.

Connection:
The plug-in terminals (TT, TT etc.) on the unit's front panel can be withdrawn for connection of the cables!
Observe the cross sections and lengths of the cables, and observe the polarity.
Note: If units are equipped with charging parts of different capacities (e. g. VAC 1215/30 DUO):
Charging Part I = 12 V / 15 A (to be used for the smaller Starter Battery of the vehicle).
Charging Part II = 12 V / 30 A (to be used for the larger Main Battery).

- 5 -
Installation of the Unit:
The charger can be installed near the batteries (short charging cables) at any location being clean and being
protected from humidity and dust.
Despite the charger's high efficiency, heat is produced, which is brought out of the casing by means of the built-in
fan. Ensure sufficient ventilation in the environment of the unit, so that the heat can be carried-off to ensure full
charging capacity. Non-observation will result in gradual reduction (reduced charging capacity).
Protect the unit from aggressive battery gas.
Any position can be chosen for installation, but the vent holes of the casing should never be covered (minimum
distance 10 cm).
Ensure a solid and vibration reducing installation using rubber bushings on an even and hard mounting surface.
Temperature Sensors (Terminals „T T“ I and Terminals „T T“ II ):
The temperature sensors control the battery temperature and the temperature-dependent charging correction.
(Characteristic lines, see also "Temperature Compensation" in this manual.)
Connect the sensor to the corresponding terminals „T T“ of the unit (any polarity).
Never mix up the batteries (I, II)! Absolutely observe the connection plan!
Sensor Installation:
The thermal contact of sensor and battery (inside temperature) should be well. Thus, it should be screwed down
to the negative pole of the battery. It is also possible to fasten it at the sidewall centre of the battery casing.
Ensure that the installation place is not influenced by any source of heat (motor unit, exhaust, heater etc.).
Temperature Compensation:
The temperature-dependent charging voltage of the battery will be adapted automatically to the battery
temperature.
For this, the supplied temperature sensor measures the battery temperature. In case of low temperatures (winter
operation), the charging voltage will be increased in order to improve and accelerate full charging of the weak
battery. Sensitive consumers are protected by a limitation of the voltage in case of very low outside temperatures.
In case of summery temperatures, the charging voltage is reduced to minimize the load (gassing) of the battery
and to extend the lifetime of gas-tight batteries.
Battery Protection (also refer to Characteristic Lines “Charging Voltage Rates and Temperature
Compensation”):
In case of high battery temperatures (depending on type: 54 °C or 58 °C), the charging current will be reduced to
50 % for reasons of safety. If the battery temperature still continues to rise, a complete disconnection will be
effected by the safety relays, as soon as the temperature is exceeded by some °C, the LED „Main Charging“ will be
flashing, but any charging data being recorded hitherto will be kept in memory. Automatic charging will be
resumed as soon as the temperature drops below the above mentioned temperature values. If the battery
temperature drops below -40 °C, the charging process will also be blocked.
The charger recognizes automatically a missing sensor, cable break or short-circuit of the sensor lines,
as well as unreasonable measuring values. In that case, it will switch to the usual charging voltage rates
of 20 °C to 25 °C being recommended by the battery manufacturers.
Option: Battery Voltage Sensor Lines (Terminals „Sense“):
Particularly in case of powerful chargers being equipped with long charging cables, it is recommendable to
measure the battery voltage via a "sensor line" directly at the battery. This allows precise observation of the
charging voltage rates.
Never mix up the batteries (I, II)! Absolutely observe the connection plan!
If several batteries are connected in parallel to a battery system, the „Sense“ line has to be connected to one of
the + poles being connected to each other.
The charger will automatically recognize and evaluate the sensor line(s).
If the sensor line is not installed or in case of a cable break or fuse failures, it will be switched to normal
operation with charging cable compensation (calculated compensation of the voltage losses on the
charging cables).
Option: Vehicle Motor Lock (Terminal "+86"):
If the motor should be started by mistake while the vehicle is still connected to mains, this unit output and a
connected external relay (12 V, max. 0.4 A) in the start circuit can be used to prevent the motor start.
The Terminal "+86" supplies voltage as long as the charger is connected to mains and switched on.

Note: In case of additional current consumption by connected consumers, the switches „Cap.“
should be set by 1 step higher.
Further actions or maintenance of the unit are not required.
Note: Several Batteries at One Charging Port:
According to the battery manufacturers, permanent parallel operation is admissible in case of two or several
batteries of the same voltage, type, capacity, as well as of the same age (history) in cross connection.
The total capacity (total Ah) should be set correspondingly using the selector switch „Cap.“.
Mains Switch (Unit Rear):
Set the mains switch to position „O“ (OFF) prior to any connection task. The unit is switched-on by position „I“.
Indicator Lamps (Each Charging Port):
„Battery Full“ (Battery fully charged, green):
If it is lighting: Battery (batteries) has (have) been charged to 100 %, trickle charging U2, finished.
If it is flashing: Main charging process is effected in the charging phase U1, charging state is increasing
from approx. 75 % to 100 %.
Off: Main charging process is still being executed in the phase I.
„Main Charging“ (Main charging, yellow):
If it is lighting: Main charging process is effected in the phase I and after that in the charging phase U1.
Off: Trickle charge U2.
If it is flashing: 1. Disconnection of the battery protection: Temperature of battery A, B <-40 °C or
overtemperature (depending on the type: 57 °C or 63 °C),
automatic reset after slight cooling down.
2. External battery overvoltage >15.50 V after 20 seconds,
Automatic reset at <12.75 V after 30 seconds.
„Power / Attention“ (Mains, red):
If it is lighting: Mains supply is available, charger is working properly and is ready for operation.
If it is flashing: 1. Disconnection Safety Timer: Duration of the charging phase I was too long,
battery defective (Short circuit of cells), too many consumers or switch
"Cap." had been adjusted too low.
Check battery. Reset is only possible by switching the mains switch to OFF.
2. Internal unit failure (overheating), automatic reset after cooling down.
3. Reverse battery (+ and - are mixed up).

Charging Process IU1oU2:
A new, complete main charging cycle will be executed:
After a power failure or disconnection by means of the mains switch (position „O“), the unit plug or mains plug
must be withdrawn.
In case of a lower deviation of the battery reset voltage of 12.75 V beyond the maximum charger current for
30 seconds due to high load.
1. Charging aid for totally discharged battery: From 1.0 V, preliminary gentle charging with a small current rate
up to 8 V.
2. Maximum charging current (I-Phase) in the mean voltage range from 8 V to the beginning of the U1-phase
for short charging times. The LED „Main Charging“ is lighting, and 75 -80 % of the capacity will be charged.
The duration of the phase I depends on the battery conditions, the floating load and the charging state. The
charger records the charging process and switches automatically to the next phase U1. If the duration of
charging phase I was too long, the charger will be switched-off (safety timer against cell defects etc.), and
the LED „Power/Attention“ is flashing.
3. During the U1-Phase (LED „Main Charging“ is lighting) the battery voltage will be kept constant on a high
level. The green LED „Battery Full“ is flashing, and the additional high battery capacity of more than 80 %
will be charged. The battery charging current is decreased slowly while full charging is increasing. The
charger controls the charging time as well as the charging current. From these values and from the course
of charging being recorded during the phase I,
the charger determines the 100% full charge point of the battery for automatic commutation to U2.
In contrast to conventional chargers with fixed default values for charging current commutation, an
unnecessary long U1-phase is avoided, which might be caused by floating loads being eventually also
supplied, and which are falsifying the charging current. „Main Charging“ will stop lighting.
4. U2 Phase („Battery Full“ is lighting permanently): The charger has now switched to the lower voltage for
trickle charge maintaining 100 % charge of the battery. Only the low compensating recharging current is
flowing, which is determined by the battery, and which is required for constant conservation of the full
charge.
5. Battery Regeneration:To ensure a circulation of acid accumulation in case of extended periods of trickle
charge (due to e. g. stop periods of the vehicle), the charging voltage rate will be raised automatically to U1
twice a week for one hour. After that, it will be returned directly to U2 (U3).
Note: During the phases U1, U2 (U3) (Battery Full) almost the total charger current is available
for additional supply of consumers without any discharge of the battery.
Sequence of the Charging Process:
1. Preliminary charging of totally discharged battery, gentle initial charging
current (I-Phase)
2. Main charging constant, maximum charging current (Phase I)
3. Main/Full charging constant charging voltage 1 (Phase U1)
4. Full/Trickle charge constant continuous charging voltage 2 (Phase U2)
