How to set the battery charger current?

The maximum charging current can be adjusted by the knob on the XTS or via remote control RCC-02/03 on the other models or on the XTS with the module TCM-01. The parameter {1138} is part of the basic parameters of the device and must be adjusted at commissioning depending on battery capacity. It will be chosen in principle a value between 0.1 and 0.2 x the nominal battery capacity C10. (I.e. 10A for a battery of 100 Ah/C10)

What protections are in place for the battery?

The battery is protected against deep discharge by stopping the inverter if the low voltage disconnection level {1108} is reached. The indicator (52) flashes once when the battery has reached the disconnection threshold and the inverter will stop shortly after {1190}. This threshold can be dynamically corrected {1191} with an advanced algorithm that computes automatically the battery voltage compensation in function of the instantaneous power. This correction may also be manually fixed {1532} by setting the low voltage disconnection at full load {1109}. These dynamic corrections can be deactivated by setting the parameter {1191}. The inverter will stop immediately if a critically voltage of 1.5V/cell is reached. The inverter will restart automatically when the battery voltage has reached the restarting threshold {1110}. This restarting threshold {1110} can be automatically readjusted if the parameter {1194} is activated, in order to better protect the battery against repeated cycling in an “almost empty” state of charge. The restarting threshold is then incremented {1298} up to a maximum value {1195} whenever the LVD (low voltage disconnection) is reached. The restarting threshold will be reset to its initial value when the value of parameter {1307} is reached. If the inverter is repeatedly {1304} encountering a low voltage disconnection in a short period {1404} it will stop permanently and will only start again via an operator’s manual restart.

What kind of electronic protections are implemented in Xtender?

The Xtender is protected electronically against overloads, short-circuit, overheating and reverse current (cabling of a voltage source on AC-Out).

What happens in the event of overload or short-circuit at the output?

In the event of overload or short-circuit at the output, the inverter stops for some seconds {1533} {1400}, and restarts. If the inverter is repeatedly encountering this situation {1300} in a short period, it will stop permanently and will only start again via an operator’s manual control.

What happens if the battery voltage exceeds the value set by the parameter?

If the battery voltage exceeds the value set by the parameter {1121} the inverter stops and starts up again when the voltage is less than {1110}. If the Xtender is repeatedly encountering this situation 3 times during one minute, it will stop permanently and will only start up again via an operator’s manual control.

What happens if there is insufficient ventilation, increased ambient temperature or obstructed ventilation?

Insufficient ventilation, increased ambient temperature or obstructed ventilation may lead to overheating of certain internal components of the unit. In this case, the device will automatically limit its power output as long as this abnormal situation persists.

What are the default auxiliary contacts functions?

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 when the charge cycle has reached floating {1516}, or when the “Aux. 1 deactivation voltage” {1255} is reached during a predetermined time {1256}.
• Contact no. 2 (AUX 2): alarm contact by default. It is deactivated when the inverter is out of service or is working at reduced performance, either because of manual control or if there is an operational fault such as overload, under-voltage of the battery, over-temperature, etc.

How can the entry command function be activated?

The function is activated by opening /closing a potential free contact, or by applying a voltage on the entry.

How to wire if the function is used in the mode active when contact is open?

If this function is used in the mode active when contact is open (such as the emergency stop, for example), the unused remote entries (in the other units) should be bridged (equivalent to closed contact). The dedicated functionality will then be activated when the drive contact opens which is connected to one of the units.

How to setup multi-unit configuration?

Several Xtenders can be used in the same system, either to create a three-phase system or to increase the power output of a single or two phases. The implementation of this configuration requires particular precautions and it must be installed and commissioned by qualified personal only.

What do you have to consider during commissioning a multi-unit system?

When a multi-unit system is commissioned, the software version of every unit will be automatically checked and units may refuse to start in case of incompatibility. If so, an upgrade of every unit is required with the RCC-02/-03 to the most recent software version available by the manufacturer. (Read the RCC-02 user’s manual to perform this operation).

What is required in Multi-units system?

In Multi-units system every Xtender in the system shares the same battery bank. Separate battery bank are no allowed. In these multi-unit systems, the units must be connected via a communication bus by a cable (art. no. CAB-RJ45-8-2) of a maximum length of 5 metres. Various application examples are described from fig. 12 to fig. 19 of Appendix 1.

What is recommended in multi-unit system?

In multi-unit system, it is recommended to use the automatic LVD dynamic compensation. See parameter {1532}.

How is each unit controlled in configuration with several Xtenders?

In configuration with several Xtenders, each unit is controlled independently using the ON/OFF push button (41). When the on/off control is given via the RCC-02/-03 remote control, it is applied simultaneously to all units.

What do you have to consider in three-phase system?

Three Xtenders of the same voltage (power or type can be different) can be used and combined in order to establish a three-phase grid. An example of cabling in three-phase is given at figs. 13.-14 of the appendix. When 3 Xtenders are wired to form a three-phase grid, the wired phases at the input determine the jumper position for selecting the phase (10). It is vital to determine and select the phase for each Xtender. If the grid is not available at the input of the master unit (phase 1), all the units of the system will switch to inverter mode. If only a single-phase source is available, it must be connected to phase 1. The other two phases will therefore be supplied by the other two working units in inverter mode.

What has to be taken into account in increasing the power by paralleling units?

Up to three Xtenders of same type – power and voltage- can be wired in parallel in order to increase the system’s rated power output. In this configuration, all the AC-in inputs of the Xtender must be wired. The most recent unit (according to the serial number) in the phase will act as the master and will decide on the operation or suspension of the units in parallel according to the load. The yield of the installation is therefore still optimal. It is possible to deactivate the master/slave mode with the parameter {1547}. In that case, the load search mode is disabled. An example of parallel connection is given in fig.12 Appendix 1 and the comments.

What is required if the current of the source (per phase) is greater than 50A (XTH and XTM) or 16A (XTS)?

If the current of the source (per phase) is greater than 50A (XTH and XTM) or 16A (XTS), а protection device must be installed on each of the 2 or 3 devices connected to the same phase with 50A max (XTH and XTM) or 16A (XTS). If the power source is limited to 50A (XTH and XTM) or 16A (XTS), only one protection device is enough.

How do you connect the BTS-01 temperature sensor?

The temperature sensor, BTS-01 is supplied with a 3 m cable fitted with RJ11/6-type plugs. It may be connected or disconnected at any time (including when the device is in use) using the corresponding socket (2) marked “Temp. Sens.” on the Xtender. Plug the connectors into the socket (2) until they click in. The temperature sensor sleeve may simply be stuck onto the battery or directly next to it. The temperature sensor will be recognised automatically and the correction made immediately.

How is the main ON/OFF function?

The main ON/OFF function may be obtained by connecting a potential free contact (1) between terminals 1 and 2. When this contact is closed, the Xtender is stopped.

How to use RCM-10?

Terminals 3 to 6 of RCM-10 are used as input control as described in Sect. 9.3- p.36. The function dedicated by programming can be activated by a dry contact (7) between 5 and 6 with a connection between 3 and 4, or by an AC or DC voltage of 60 V rms max. between terminal 4 and 5.

How to set the main ON/OFF function?

The function “main ON/OFF” (1) can only be controlled by a potential free (dry) contact.

How to make the complete stoppage of the whole system?

The ON/OFF switch is used only for the complete stoppage of the whole system. This switch is not available in the XTM. The function can be added with the use of the remote command module RCM-10.
