RS232-Port
The RS232 interface is used for download the 'Field exciter firmware package'.
The firmware download is activated by setting S2:1-2 before the auxiliary voltage is switched ON.
Field exciter mode is S2:3-4 (default).
Diagnostics
All messages are sent to the armature converter and displayed in Signals 04.26, 04.27, 04.36 and
04.37. If the communication is broken or node numbers are mixed up the simple fault display on the
SDCS-FEX-4 can be used.
Therefore the unit is equipped with two small LEDs.
V730 = Green
V731 = Yellow
Following messages are displayed:
Both OFF
No 24 V supply
Green and yellow continuous No firmware or S2:1-2
Green blinking 16 A / 25 A / 35 A output active, waiting for
DCSLink communication
Green continuous 16 A / 25 A / 35 A output active,
DCSLink communication OK
Yellow blinking 5 A output active (X100:2), waiting for
DCSLink
communication
Yellow continuous 5 A output active (X100:2), DCSLink communication OK
Green and yellow toggling:
Line reactors (L3) ,
Autotransformer (T3) ,
Fuses (F3.x) .
