11. Configuration
The SINEAX B 811 unit has to be opened before it can be
configured (see Section 8. “Withdrawing and inserting the
device”).
11.1 Switching output signals A1 and A12 between the
signal ranges 0…20 mA or 4…20 mA
The range of the outputs can be switched from
0…20 mA to 4…20 mA or vice versa depending on the
positions of jumpers J 202 and J 203 (Fig. 14).

11.2 Communication connector
Connect the communication connector to output A1 or
A12 (Figs. 10 to 13). Signals are then transferred in both
directions between the hand-held terminal and the
transmitter via the SINEAX B 811.
When using the field output A12, the 250
Ω
burden
connected across output A12 in the power supply unit
can be switched in and out of circuit with the aid of
jumpers J 204 and J 205 (Fig. 14).

11.3 Response of the output signals A1 and A12 for a
fault in the measurement/supply circuit
The response of the output signals A1 and A12 can be
set with the aid of switches 1 and 2 on the DIP switch
S 201 (Fig. 3).

The power supply unit must be capable of supplying
a brief current surge when switching on. The
transmitter presents a low impedance at the instant
of switching which requires a current I

The red LED may also light briefly (< 1 s). The green
LED must light immediately.
The signal for indicating a failure in the measurement/
supply circuit is only enabled after a delay of typically
2.5 s. The output contact remains in its reset state
during the switch-on delay!
