Function of diagnosis LED („DIAG“) red
LED off: Telegrams are filtered or blocked (both directions)
LED on: Telegrams are retransmitted without being filtered (at least one
direction)
Function of operation LED („RUN“) green
LED off: device off, no voltage on superordinate line
LED on: device on, voltage on both lines
LED flashing: no voltage on subordinate line
4. Installation
The device is snap-fastened on the DIN rail until the latch is heard to
engage, with the connecting terminals pointing downwards.
5. Connection
The superordinate line is connected with the left-hand terminal (FIG.
A
,
(8), terminal „HL“). This terminal supplies power to the device electronics
so that it is possible to report a bus voltage failure of the subordinate via
the superordinate line. The subordinate line is connected to the right-
hand terminal (FIG.
A
, (7), terminal „UL“).
Removal info
: Do not lever out the connecting termianal from below.
Risk of shorting the bus voltage which is not available during the short-
circuit.
Allocation of the physical address
Press the programming button (2)
