The charger operates in accordance with the Wa characteristic specified in DIN 41774. This characteristic is optimized by current pulses at the end of the charge. This current characteristic curve, which slopes downwards as the battery charge level rises, allows for optimal charging. Safe functioning of the battery charger is ensured by the reliable charging electronics monitoring the battery charging operation. The technical data and specifications regarding the connection requirements can be found on the identification plate and in the operating instructions. These specifications must always be heeded. Operation of the battery chargers is subject to the provisions contained in the relevant legislation and regulations, from industry association guidelines (VDE), from the EMC directive (2004/108/EC) and directives issued by local authorities. Excerpts of such provisions are given in chapter E1. The battery charger must only be used for charging batteries which are of the type stipulated by the manufacturer. The battery charger must always be operated with the housing closed. It is forbidden to loosen and remove parts of the housing or any type of suppressor elements. Do not place any objects on the charger or climb onto it. The user is responsible for choosing the assembly location. He must check whether the battery charger will affect any devices that are sensitive to electromagnetic interference. The assembly location of the charger must be chosen so that operation (high DC currents generate magnetic interference fields) does not affect the functioning of sensitive electromagnetic devices and magnetic data media, such as pacemakers, monitors, disks, magnetic tapes, magnetic cards, watches, see “Charger Assembly” on page 5. The user must ensure that the SLT 100 battery charger is used only within its design limits and that all danger to life and limb of the operator and third parties is avoided. Furthermore, applicable accident prevention and other health and safety regulations, along with the operating and maintenance guidelines, must be observed at all times. M The battery charger must only be operated when stationary. The user must also ensure that all persons operating the battery chargers have read and understood these operating instructions. Additional components may only be installed after a written approval by the manufacturer has been obtained. User obligations: User within the meaning of these operating instructions is any natural person or legal person who either uses the battery charger himself, or on whose behalf it is used. 1115.GB In special cases (e.g. leasing or renting), the user is deemed to be the person, who, in accordance with existing contractual agreements between the owner and the user of the SLT 100 battery charger, is charged with the observance of the operating duties. 1 B Description of battery charger 1 Technical description The SLT 100 battery charger is designed for the fully automatic charging and recharging of lead batteries and is equipped with a special electronic charging system (1, 2). The rated charging current specified flows at a charging voltage of 2.0 volts per cell. The battery must be assigned so that the initial charging current is approx. 16 Amperes per 100 Ah of battery capacity. 1 The difference lies in the initial charging current – see data plate (3). 00 1 SLT Initial charging voltage: 24, 48, 80 volt depending on type Initial charging current: 20 A-160 A, depending on type The battery charger is protected on the secondary side by a fuse (5) acting as a short circuit protection and by a sensor to limit the transformer temperature. 2 3 To ensure the operational safety of the system, only self-cooled stacked silicon rectifier elements (4) are used. Stray field transformers (6) are used to comply with the specified charging characteristic. The stray field transformers are equipped with additional primary tapping to DIN 41 774, corresponding to +10 %, +5 %, 0 % and -5 % to allow for mains voltage deviations. Z 4 6 5 Modifications should only be carried out by the manufacturer’s service department. 1115.GB SLT 100 2 Z Charging electronics extra option (Aquamatic) Z The Aquamatic serves to control an external solenoid valve of an automatic water refilling system. When a cell voltage of 2.4 V/cell is reached, a relay contact (normally open contact, contact rating 5 A) is triggered by the following pulse train: Characteristic curve: Wa Charging characteristic Uz Cell voltage (V/cell) - 6-7 pulses with a duration of 3 sec., then maintained contact for 7 min. IL The contact is potential-free, a 230 V power connection of the battery charger is available. Charging current (in % of rated current) IdN Rated battery current The curve of the Wa characteristic is determined by points 1), 2) and 3): Electrolyte circulation: Z M If the battery remains attached to the charger at the end of the charging time (T3), there will follow an 8 minute trickle charge every 8 hours and after 24 hours a one-off compensation charge lasting 2 hours. The charger has an option for controlling an electrolyte circulation pump. Observe the respective manufacturer’s guidelines! It should only be connected by the manufacturer’s service department. 1) 100 % IdN at V = 2.0V/cell 2) 50 % IdN at V = 2,4V/cell 3) 25 % IdN at V = 2,65V/cell The Aquamatic and electrolyte circuluation systems are monitored. Any faults are displayed on the front panel. 2,8V M The connection of external additional equipment may only be carried out by skilled electricians. 2,4 Z To attach additional external equipment, contact the manufacturer’s service department.

Progress of the charging operation is shown by the light-emitting diodes (7). An electronic monitoring unit detects the gassing time and determines the optimum recharging time from the charged capacity (Ah balancing). Charging starts automatically with a time delay (approx. 10 sec. to protect the plug contacts) after the battery has been connected to the charger. The control key (12) can be used to cancel operation at any time. The standby (13), charging (7), charging completed (9), and compensation charge (8) conditions are indicated by the LEDs (13,7,9,8). An automatic safety cut-out is provided, when the gassing voltage has not been reached within an initial charging phase of 12 hours. Z IP 22 Ambient conditions: The charger is self-cooled and is designed for a max. ambient temperature of 40 °C and a max. relative humidity of 80 %. M The charger must only be stored in enclosed areas. Operation of the battery charger is only permitted in spaces specially provided for this purpose. 4 Identification label, e.g. E230 G24/50 SLT 100 (see “Sample Data Plate” on page 18) Z The identification label is located on the rear wall of the unit.

The surface must not consist of flammable material. Starting up the charger M Fuse protection of the mains cable to the battery charger is the responsibility of the customer. The fuse must have a delayaction release characteristic. Where automatic cut-outs are used, they must have a D, S or K rating (for the rated current consumption of the charger see data plate). To ensure adequate selectivity, the backup fuse should at least be 10 % above the current consumption of the charger. The charger must be protected against excessive contact voltage in accordance with the regulations of the local electricity provider. Procedure - Remove packaging material (film or cardboard). - If the battery charger was delivered on a transport pallet, lift the battery charger from the transport pallet This does not apply to pallets on which the battery charger is permanently mounted. These pallets have a fireproof base. - Packaging material is to be disposed of correctly. In addition to the restrictions listed in the operating instructions, national requirements must be observed when choosing the place of installation. 5 D Battery - Servicing, recharging, replacement 1 Safety regulations governing handling of lead-acid batteries the Maintenance personnel: Recharging, servicing and replacing of batteries must only be performed by qualified personnel. The instructions contained in this operating manual, and the instructions as prepared by the battery supplier must be observed, when performing the above operations. F Metal watch bracelets, bracelets and necklaces must not be worn when handling batteries! F Batteries contain dissolved acid, which is toxic and caustic. For this reason protective clothing and goggles must be worn whenever work is undertaken on batteries. Avoid physical contact with battery acid. If clothing, skin or eyes accidentally come into contact with battery acid, liberally rinse the affected parts with clean water. If it has come into contact with the skin or eyes, seek medical attention. Spilled battery acid should be neutralised immediately with plenty of water. Fire protection measures: Smoking and open flames are not permitted when handling batteries. There must be no flammable substances within at least 2.5 metres and no equipment capable of creating sparks (e.g. machine tools) within at least a 1 metre radius of the truck when it is parked for battery recharging. It is forbidden to operate devices with a high surface temperature (e.g. soldering irons, heater blowers, etc.). Place the charger only on a solid and secure surface. M F The surface must not consist of flammable material. Charging batteries leads to the generation of explosive gases. Sufficient ventilation must be provided during charging and at least for one hour after charging has been completed. The room must be ventilated. Check the ventilation system each time before you charge. Fire fighting equipment must be held ready. M Parts that can be sucked in due to the suction of the ventilation fans must not be stored in the vicinity of the battery charger. Clogged ventilation slits cause overheating and fire hazard. F Do not use water to cool overheated battery chargers. 1115.GB Battery servicing: The battery cell screw caps must be kept dry and clean. Terminals and cable shoes must be clean, lightly greased with pole grease and must be securely tightened. 6 E Operation 1 Safety regulations relating operation of battery chargers to the Charger assignment: The charging procedures, or charging characteristics, as well as the charging equipment must be adapted to the operating conditions and technical data of the batteries. To ensure the safety of a battery charger, the equipment (charger, cables, battery) must be in good working order. Operation must be in such a way that no danger is posed to persons. F Battery charging: The connector must only be disconnected from the socket after the battery charger has been switched off. The top of the battery cells must be exposed during recharging to ensure adequate ventilation. Do not rest any metal objects on the batteries. Check the insulation before using the charging cables and connectors. Faults and defects must be rectified immediately by trained personnel (see “Safety instructions to be observed during servicing” on page 11). The following items are taken from the legal requirements and guidelines of German and international associations and organizations. Ventilation: Battery chargers must be set up so that they are not exposed to charging gases and electrolytic mist. Z M Note the regulations. battery manufacturer’s Do not exceed the temperature limits stipulated by the battery supplier. This applies also to any heating that may occur as the battery is recharged. Chargers and batteries must therefore be housed in separate locations wherever possible. If this is not possible, adequate natural and artificial ventilation must be provided to ensure that the gas mixture generated during charging will lose its explosiveness. Functional test: When commissioning new charging equipment, and thereafter at adequate intervals, checks must be performed to ensure correct operation of the battery charger, and especially correct functioning of automatic charging switches and measurement instrument display. At the start of charging, the amperage and voltage must be checked in order to detect any irregularities in the patterns of the battery or charging equipment. Mains supply: If, in the event of mains voltage fluctuations lasting over a long period of time, the output voltage changes, the battery chargers must be readjusted ensuring that the admissible limits as indicated by the battery supplier are observed (e.g. final charging current in the case of lead batteries). Short-time mains voltage fluctuations may be ignored. 1115.GB Z 7 2 Description of the operating controls and indicating elements 2 1 Item Operating control / indicating element 1 “Standby” LED (green) 2 “Charging” LED (yellow) 3 Control key 4 3 5 6 7 Function t lights up when the battery charger is ready for operation t indicates the charging process t The control key has the following functions: - Stop / Continue charging (break function) - Manual equilising charge - Charging state indicator 4 LED ”Compensation charge” t indicates the equilising charge 5 LED “Warning messages” (yellow) t Indicates faults that affect charging, via a flashing code. 6 7 LED “Service messages” (red) “Charging completed” LED (green) Flashing pulses: Meaning: 2 Incorrect battery voltage 3 Safety charge exceeded (Main charging time or recharging time in case of pulse charging) 4 Excess temperature 5 Mains failure (is only indicated when the charging state indicator is queried) 6 Warning requested by the optional board.

During charging the electrolyte circulation pump is switched on for approx. 2.5 min. and off for approx. 7 min. The battery charging device with a built-in pump and hose system is suitable only for batteries with electrolyte stirring. Charging is recognised by the charge switch insofar as it: 3 - Detects the connected battery. - Detects a charge current. User obligations: The user must make sure that only batteries with electrolyte stirring or with a hose system are permitted to be charged. M The pump must not be operated without counterpressure. 2 Charger Assembly F The battery charger must not be operated outdoors. During the pulse charge phase there is no electrolyte circulation. The pump is switched off. 4 It is forbidden to store food in the vicinity of battery chargers. Z The VDE 0510 safety regulations must be observed. Internal electrolyte circulation: Internal electrolyte stirring is automatically switched on at the beginning of the charging procedure. Electrolyte stirring mixes the acid before the gassing phase. Z In the main charging phase, the battery’s energy consumption increases so that the recharging phase can be shortened. The internal charging electronics detect via the sensor that the pump is switched on and reduce the recharging time. This shortens the total charging time at the same battery charge level. 1115.GB F Description of the device During the main charging phase, batteries without electrolyte circulation generate acid layers. The charging factor is set according to the charging device. Choose the assembly location so that: - There is sufficient ventilation. - The flow of cooling air through the charger is not restricted. It must not be installed close to radiators or similar heat sources. - No flammable gases or dust mixtures can penetrate inside the charger. - The charger is placed only on a solid and secure surface. The surface must not consist of flammable material. - The bottom of the charger is approx. 0.5 m above the battery to be charged. Electrolyte circulation (EUW) 13 The internal electrolye stirrer consists of the following parts: - An additional switch contact to switch on the pump; - A sensor to switch or adapt the charging factor; - A membrane pump with an air filter and air pressure monitor. The pump delivers a constant pressure of 100 mbar and overcomes an acid level of ca. 80 cm in the main charging phase; - A connecting hose with an air plug connection in the pilot contacts of the charging connector.
