5. Window monitoring the EN54 power supply parameters.
The window monitoring the PSU parameters appears after configuring a new connection or after
loading the previously saved configuration. The window contains the title bar with the name of the connected PSU
and the menu bar divided into three tabs: preview, charts and history.
5.1 The „Preview” tab
After loading the connection configuration, the ”Preview” tab will be displayed. Press the icon in the
upper left corner to connect the power supply. Once the connection is established, the current parameters of the
power supply, automatically updated according to the refresh cycle set during configuration, will be displayed.
Pressing the icon enables opening the connection configuration window and changing certain
communication parameters. If it is necessary to edit the parameters that are not available from this level, close the
current connection and open a new one ("New power supply" from the main window).
Fig. 16. The „Preview” tab of the EN54 power supply.
Graphically, the tab of the parameters preview is divided into sections, which symbolically represent
the most important components of the power system.
The electrical parameters at the AUX1 and AUX2 outputs (output voltages and total current), the status of
the 230V mains supply (ON/OFF) and the voltage value are monitored. What is more, the battery block shows the
actual voltage, battery charging level and the internal resistance of the battery circuit. The TEST button performs a
remote battery test at any time. The graphic symbols of the technical outputs of power supply are located in the
lower right corner. In case of failures, their contacts switch from closed to open position and the backlight changes
to red. The EXTi window located in the central part indicates the status of the input of collective failure – in case of
the input activation its backlight changes into red. The EXTo window indicates the status of the controlled relay
output - if the relay is activated, it changes to red. The TAMPER window indicates the status of the tamper input –
in case of open circuit (enclosure opening) its backlight changes into red.

Mains supply status (mains supply value)
230V mains supply:
- green backlight if the voltage is in the range between 230V -15% - +10%
- blue backlight if the voltage is below 230V – 15%
- red backlight if the voltage is over 230V +10%
No 230V mains supply
