Resolution for voltage measurement amounts to 0.1V, for current measurement: 0.1A. Displayed
voltage and current rates are only approximate. For higher accuracy, a multimeter shall be used.
3.2 Overview of current failures.
If any incorrect electrical parameters occur, the PSU will signal the failure by illuminating an appropriate LED
on the panel or by activating an acoustic indication (provided it has not been switched off). After pressing the ‘OK’
button, the panel display will show a code of the fault that trigger the failure. If more than one failure occurs
simultaneously, another pressing
the
‘OK’ button will display the next failure code.
In chapter 9 all possible failure codes that can appear during the PSU’s operation have been shown. Each
code is accompanied by an appropriate LED indication on the panel, acoustic indication and switching of a
dedicated technical output.
3.3 Overview of failure memo.
The device remembers 30 last failures in non-volatile memory which enables a subsequent overview.
Entering the failure memo overview mode:
With the “<”, “>” buttons choose the FLt position and approve by pressing “OK”. The number of the failure will be
displayed, then its code. Pressing “OK” again will display the next failure in the memory.
3.4 Setting the communication parameters of the PSU.
Communication in the RS485 bus requires setting appropriate communication parameters in all power
supply units and assigning appropriate addresses.
All power supplies have a preset address 1.
3.4.1 Setting the parameters of the serial port.
- press the ‘<,>’ right and left-most buttons simultaneously
on the LED panel
- press ‘OK.’ after appearing of ‘Adr’
- with ‘>’ or ‘<’ set the address from 1 to 247.
- confirm the address with the ‘OK’ button
