Connecting The Power Supply; Programming The Transmitter - Camille Bauer SINEAX V604 Betriebsanleitung

Notes
9.1.1 Connection to thermo-couples (connection
diagram No. 8)
With instruments programmed for thermocouple connec-
tion with internal cold junction compensation, compen-
sating leads must be used from the thermocouple to the
SINEAX V 604.
No line balancing is required.
9.1.2 Connection to resistance thermometers or poten-
tiometer
9.1.2.1 Two-wire connection (connection diagram No. 4)
Terminals 1 und 6 must be connected in the case of a two-
wire measurement. The infl uence of the lead resistance is
compensated automatically by a lead resistance measuring
circuit. This is done by shorting the sensor and pressing
the calibration button S1 (located behind the front cover,
see Fig. 2) for at least 3 seconds. Wait until the green LED
(stand-by signal) no longer fl ashes. Remove the short-circuit
from across the sensor.
9.1.2.2 Three-wire connection (connection diagram No. 5)
It is assumed that the three leads of a three-wire connec-
tion have identical resistances and no compensation is
necessary. The lead resistance must not be greater than
30 Ω per lead.
9.1.2.3 Four-wire connection (connection diagram No. 6)
The four-wire measurement is independent of lead resi-
stance within wide limits and therefore no compensation
is necessary. The lead resistance must not be greater than
30 Ω per lead.
9.2 Measuring output leads
Connect the output leads for output A1 to terminals 4 (–) and
9 (+) and for output A2 (fi eld indicator) to terminals 3 (–) and
8 (+) as shown in Fig. 9.
Note: The maximum permissible external resistance R
of the transmitter must not be exceeded (see Section
"5. Technical data").

9.3 Connecting the power supply

Connect the power supply to terminals 5 (
shown in Fig. 9.
A two-pole switch must be included in the supply connection
where facility for switching SINEAX V 604 off is desired.
Note: An external supply fuse must be provided for DC
supply voltages > 125 V.
9.4 Connecting the output contact
Connect the output contact signalling leads to terminals 13,
14 and 15 (see Fig. 9 and Table 6).

Terminals 13 and 14 are connected in the event of a power
supply failure.

10. Programming the transmitter

A PC, the programming cable PRKAB 600 and the pro-
gramming software VC 600 are needed to program the
transmitter.

1. It is not permitted to use the programming
cable PRKAB 600 for programming devices
of other manufacture.
2. (This point only applies to the "intrinsically
safe" [EEx ia] IIC version of the SINEAX
V 604 transmitter)
The programming connector (7) is not
electrically insulated from the intrinsically
safe measuring input circuit. It is therefore
essential to observe the following:
– Programming may only be performed
using the programming cable PRKAB 600
(certifi cate Ex:
PTB 97 ATEX 2082 U).
– The voltage applied to the FCC connector
must not exceed 253 V. For this reason,
no devices may be connected to the in-
put circuit of the V 604 that have a supply
> 253 V. Pay special attention to this when
measuring DC voltages with NLB686
numbers. Note that in this case the compo-
nent certifi cate is void. We also recommend
that for safety, the Ex symbol should be
crossed out to make it invalid.
– The programming connector (7) max only
be used briefl y.
– The plug connector between the socket
connector and the expandable cable
(see arrow on the diagram) must not be
withdrawn when the expandable cable is
connected to the programming instrument.
For this reason, the expandable cable must
be plugged into the socket connector before
establishing the connection between the
device and the PC.
