STUDER Innotec Xtender 4.1 CHOICE OF SYSTEM The Xtender may be used in different system types, each of which must meet the standards and particular requirements associated with the application or site of installation. Only an appropriately qualified installer can advise you effectively on the applicable standards with regard to the various systems and the country concerned. Examples of cabling are presented in appendix I of this manual, fig. 5 and following.
STUDER Innotec Xtender The Xtender can be operated with any earthing system. In all cases it is imperative that the protective earth be connected in compliance with the applicable standards and regulations. The information, notes, recommendations and diagram mentioned in this manual are subject to local installation regulations in every case. The installer is responsible for the conformity of the installation with the applicable local standards. 4.2.
STUDER Innotec Xtender 4.3 RECOMMENDATIONS FOR DIMENSIONING THE SYSTEM 4.3.1 Dimensioning the battery The battery capacity is dimensioned according to the requirements of the user – that is 5 to 10 times its average daily consumption. The discharge depth of the battery will therefore be limited and the service life of the battery will be extended. On the other hand, the Xtender must have a battery capacity that is large enough to be able to take full advantage of the performance of the equipment.
STUDER Innotec Xtender 4.4 WIRING DIAGRAMS The diagrams shown in the appendix of this document are subsidiary. The applicable local installation regulations and standards must be adhered to. The elements referred to with an uppercase letter denote the alternate current (AC) part. The elements referred to with a lowercase letter denote the direct current (DC) part. 4.5 CONNECTING THE BATTERY Lead batteries are usually available in 2 V, 6 V or 12 V block types.
STUDER Innotec Xtender The clamps must be carefully fixed and tightened sufficiently to guarantee minimum loss. Insufficient tightening may cause dangerous heating at the connection point. For safety reasons, we recommend an annual check on the tightness of all connections. For mobile installation the connections should be checked more frequently for tightness. 4.5.2 Connecting the battery (Xtender side) Insert the conduit glands supplied on the battery cable before tightening the cable clamp.
STUDER Innotec Xtender As of the connection of the battery, it is necessary to check that the configuration values of the Xtender are conform to the recommendations of the battery manufacturer. Non-conforming values may be dangerous and/or seriously damage the batteries. The default values of the battery’s charge threshold level are shown in fig. 3a and specified in the configuration table p.41.
STUDER Innotec Xtender An additional earthing terminal (15) is present between the two fastening screws at the bottom of the unit. It can be used instead of a connection on the input terminals of the device, particularly when cable cross-sections used at the output do not allow the use of a three-wire cable (live, earth and neutral) through the conduit glands of the connection cables of the input and output (AC IN and AC OUT), or when the earthing of one of the poles of the battery.
STUDER Innotec Xtender 4.5.11 Connecting the remote command module RCM10 (XTM only) The remote command module RCM10 can be “hot plugged” on connector “RCM-10” (15) without stopping the operation of the system. A contact free of potential (1) can be connected between terminals 1 and 2. When this contact and closed, the apparatus is stopped as described in Chap. 7.1 p. 30. Terminals 4 to 6 of module RCM-10 are used as command entry as described in the chap. 6.1.12 p.26.
STUDER Innotec Xtender 6 DESCRIPTION AND FUNCTIONING 6.1 CIRCUIT DIAGRAM User manual V.3.2.
STUDER Innotec Xtender 6.2 DESCRIPTION OF THE MAIN FUNCTIONS 6.2.1 Inverter The Xtender is equipped with a high-performance inverter which supplies a perfect and very precise sine wave. Any unit designed for the 230 V/50 Hz electrical grid may connect to it without any problem, up to the rated power out of your Xtender. The inverter is protected against overloads and short-circuits.
STUDER Innotec Xtender When the generator stops, the change from transfer mode to inverter mode normally takes place without any interruption of the output voltage . The interruption will be 40 ms in the event of the immediate loss of input voltage at “AC IN” provided the UPS mode {1435} is not deactivated. 6.2.3.
STUDER Innotec Xtender case the LED “charge” (4) goes out. The consumers must ensure that they have average consumption that is less than the power of the source (generator or public grid) in order to avoid a complete discharge of the battery. These situations are set out in the figure below. Fig.
STUDER Innotec Xtender output to ensure that the battery is charged. Once the charge current decreases by going into “power sharing” mode, the indicator (45) flashes. The limit value of the input current is set by the configuration {1107} and may be adjusted via the RCC-02/03 remote control. In the case of mobile applications the installation of an RCC-02/03 remote control is recommended, in order to be able to adapt the value of the input current limit if necessary, for each connection to a limited grid.
STUDER Innotec Xtender 6.2.7 Input current controlled by input voltage When AC sources with variable power are connected to the Xtender's ACin, a particular parameter setting insure a permanent availability of the nominal power at the Xtender's output thanks to the Smartboost function. It's notably the case with "Dynawatt" 230Vac alternator coupled with variable speed traction engines. These kinds of sources have a variable voltage according to the available power.
STUDER Innotec Xtender These dry contacts are programmed by default for the following functions: Contact no. 1 (AUX 1): The contact has a function of automatic start of generator (two wires). The contact will be activated when the battery voltage is below a value, during a given time fixed by parameters {1247/48}/{1250/51}/{1253/54} The contact will be deactivated or when the charge cycle has reached floating, or when the "Aux.
STUDER Innotec Xtender When multi-unit system is commissioned, the software's version of every units will be automatically checked and units may refuse to start in case of incompatibility. If so, an upgrade of every units is be required with the RCC-02/03 and the last software version available by the manufacturer. (Read the RCC-02 user's manual to perform this operation). In Multi-units system every Xtender in the system shares the same battery bank.
STUDER Innotec Xtender 6.3.3 Combined system It is possible to combine a three-phase system with one or several phases made up of 2 or 3 Xtenders in parallel. An example of cabling is given at fig. 15. A combination of more than one inverter on only one (or two) phase is also possible.
STUDER Innotec Xtender The two remote control models are delivered with a 2 m cable by default. Cables of specific lengths (5 m, 20 m and 50 m) can be ordered. The article no. is as follows: CAB-RJ45-xx. The length in metres is specified as xx Up to 3 RCC-02/03 remote controls can be connected in series on the communication bus of one Xtender or an Xtender multi-inverter system.
STUDER Innotec Xtender 6.4.3 Remote control Module RCM-10 The optional remote control module for XTM range gives the possibility to have the 2 following function: Main ON/OFF (1) see chap.7.1 below. This operation can only be controlled by a potential free contact. Command entry (7) see chap. 6.2.12 – p. 25. This module can be plugged on DIN rail Article n°: RCM-10 Supplied with a 5m cable (max. length 5m).
STUDER Innotec Xtender 7.2 DISPLAY AND CONTROL PANEL The Xtender has a ON/OFF button and light indicators at the front of the unit, allowing clear identification of the operating mode. (41) The ON/OFF button allows the start-up or complete stop of the system. In the systems comprising several units, each unit is started or stopped individually. For a simultaneous start-up of all the units use the dry contact control (see chap. 6.2.12 – p. 25) or the ON/OFF button of the RCC02/03 remote control.
STUDER Innotec Xtender Indicated alarm Comment If the device has not yet stopped, it is recommended to disconnect all non-priority consumers and/or start up the generator. If the Xtender has stopped it will restart (Imminent) stoppage as a automatically when the battery voltage has reached the 1x result of low battery voltage. correct value again {1110}. It can be restarted manually using the ON/OFF button (41) as long as the battery voltage is higher than the critical threshold {1488}.
STUDER Innotec Xtender (44) This indicator is glowing continuously when the charger is working and has not yet reached his absorption phase. It flashes twice during the absorption phase and once during the floating phase. If the Smart Boost mode has been activated, this indicator goes out temporarily when source backup is required by users (loads).
