11. Confi guration
The SINEAX B 811 unit has to be opened before it can be
confi gured (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).
Output signals
4 ... 20 mA
0 ... 20 mA
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 fi eld 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).
Communication connected to:
Field output A12*
integrated 250 Ω resistor
in circuit, the burden at measuring
output A1 is reduced 250 Ω
Choise of A1 output signal
range 0/4 ... 20 mA
Voltage across A1 burden: 10 V
Field output A12*
integrated 250 Ω resistor
not in circuit, the burden at
measuring output A1 is not
reduced
A1 output signal range
4...20 mA only
Voltage across A1 burden: 15 V
Measuring output A1
Output signal range 4 ... 20 mA
Voltage across A1 burden: 15 V
*See "Measuring output" in the section "5. Technical
data".
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. 14).

11.4 Response of the output contact AF for a fault in the
measurement/supply circuit
The response of the fault signalling relay can be set with
the aid of switches 3 and 4 on the DIP switch S 201
(Fig. 14).

12. Commissioning
The power supply unit must be capable of supp-
lying 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 briefl y (< 1 s). The green
LED must light immediately.
OFF
The signal for indicating a failure in the measure-

ment/Supply circuit is only enabled after a delay
of typically 2.5 s. The output contact remains in its
