Alarm relay (X4)
The devices are equipped with a potential free alarm
output (relay with isolated switchover contact). This
output corresponds to a device alarm and is activated
when the device looses the power supply or the alarm
LED is constantly on. The reason for the signaling of an
alarm can be referenced in the system alarm table.

Configuration using a serial configuration cable
The serial interface provides access to the command
line. Using a serial configuration cable (500CAB06
1KGT038912R0001), the device can be connected to a
serial port of a PC/notebook.
The default configuration for the serial connection is:
57600 Baud 8N1 (8 data bits, no parity, 1 stop bit), no
hardware flow control.
The command line interface
Device is without
The command line of the 500FSD20 is similar to the
power supply
(DOS) command line known from the PC. All device
properties can be set and shown here.
