Bus mode
After programming the signal or sensor type, the raw value (0-32767) of an analog sensor input can
be written in a Holding Register (h9000 for E1 and h9001 for E2) with the bus mode activated.
The connection is made at the MODBUS RTU Slave interface. Connecting terminals: 2A (2D+), 2B
(2D-).
IO Setup
The bus mode of the inputs is set to
“
OFF
”
at the factory.
With activated bus mode, the raw values can be written accordingly into the Holding
Registers, addresses h9000 and h9001 for
“
E1
”
and
“
E2
”
.

Function and inverting for relay outputs
“
K1
”
and
“
K2
”
IO Setup
Various functions can be allocated to the relay outputs
“
K1
”
and
“
K2
”
. In case of the
same function allocation for
“
K1
”
and
“
K2
”
, these work parallel.
The inversion of the relays
“
K1
”
and
“
K2
”
is set at the factory to
“
OFF
”
(when a function
is programmed).
For switching inversion to
“
ON
”
(switching behaviour dependent on assigned function).
The relays can only pull up basically when the voltage supply of the electronics is
working. Three-phase current devices must have at least 2 line phases!

Fault indication
(2K)
Fault indication (factory setting for
“
K2
”
, non inverting).
Pulled up in operation without fault, with release
“
OFF
”
not dropped out.
Drops out in case of line and device fault and external fault at the digital input. Depend-
ing on programming in event of sensor failure.
When networked via the MODBUS Master interface, fault indication in case of faulty
MODBUS connection and fault on a member.
External error
(3K)
External fault separate with message at digital input (factory setting if terminals
bridged).
