A description of the buttons and LEDs on the PSU panel.
- scroll up /scroll down the Menu list
- approving a given entry
- switching between the parameter’s name and its nominal value
- displaying current PSU faults, pressing the button again will display the next fault
(if there are a few at the same time)
- pressing
Chile browning the PSU fault will erase the fault memo
- red LED indicates a failure
- green LED indicates presence of AC power (illuminating – mains supply,
twinkling- battery-assisted operation)
Available menu entries.
FAL PSU fault memo (20 last occurrences )
Ibd battery discharge current measurement [A]
Ibc battery charge current measurement [A]
Io2 OUT2 output current measurement [A]
Io1 OUT1 output current measurement [A]
Udc current measurement at the Wheatstone bridge’s output [V]
Uo2 OUT2
output voltage measurement [V]
Uo1 OUT1
output voltage measurement [V]
Resolution for voltage measurement: 0.1V, for current measurement: 0.1A. Displayed voltage and current rate is
only approximate. For higher accuracy, a multimeter shall be used.
•
Current failure overview.
In case of a failure (a red LED is illuminated on the panel), its code can be checked. After pressing the
button, a type of the failure will be displayed. If many failures occur simultaneously, pressing the
again will
display the next failure code.
•
Failure memo overview.
The device remembers 20 last failures in non-volatile memory. That enables subsequent overview by an
installer.
Entering the failure memo overview mode
With
choose the FAL position, approve with
, a number of the failure will be displayed, then its
code. Pressing
again will display the next failure in the memory.
•
Erasing failure memo.
Pressing
in the failure memo overview mode will cause erasing all the stored failures.
