Operation
4.1
General information
Output voltages and signalling thresholds are preset as factory default values. Power supplies after
installing require supervision by the service team as some emergency states may occur during the
operation of the device.
4.2
Operation safety
The power supply unit is a Class I device according to the standard EN 60950-1:2007/A1:2011
(IEC950), designed for connecting to a permanent, one-phase installation using an earthing cable,
according to the HD 60364-4-41:2007 Standard Electric installations at construction sites.
The metal case of the power supply units is connected to a protective terminal (PE). The circuits used
for connecting the battery, remote indication outputs and remote indication inputs are separated
from power supply circuits and from the case.
Contacts of remote indication relays are completely separated from all other circuits (including output
circuits).
Inputs of external fault indications are located on the potential of negative bus of the battery bank.
The interference filters used in the CHARGER 6 and in CHARGER 12 power supplies are equipped
with the Y class capacitors causing the appearance of the leakage current in the protective conductor
of maximum 1.5 mA for the CHARGER 6 and 3mA in CHARGER 12.
4.3
Digitale display
Power supply units allow for digital measurements of basic operation parameters of the system:
current voltage of the supervised battery bank (U), its charging or discharging current (IB), current
consumed by the VAS controllers from the 24V power supply (IO) and of the ambient temperature (T),
if the temperature sensor has been connected. The current measurement type (selected by using the
vertical arrow button) is distinguished by switching on a LED diode with the corresponding marking. In
addition, one can read the error code detected by the power supply unit controller (all diodes
indicating measurement type are switched off). This position is active only then, when an operation
error has been detected in the system and the fault indication has been activated.
A list of particular errors (many errors can be caused by a particular type of fault) is performed by
using the vertical arrow button. The long press of the arrow button allows basic operation parameters
of the system to be measured, starting with U..
4.4
Digitale communication
The front panel of the power supply unit is equipped with a USB communication socket used routinely
for servicing. The servicing software allows for diagnostic works to be performed, enabling to check
numerous operation parameters of the power supply and to modify its default settings. This output is
galvanically insulated from all other circuits of the power supply unit.
Optionally, the power supply unit may be equipped with an Ethernet interface, enabling operation
within a TCP/IP network. It has two simple service servers implemented:
- a http server for presentation of the current system state as web pages available for browsing using
a web browser;
- ModbusTCP protocol server enabling device controlling and supervision.
Detailed information can be obtained from the manufacturer.-
