Fig. 6. Withdrawing the device.
There are two parts to the casing, the shell (8) and the cover
(9). The are held together by robust pegs and can be simply
assembled manually. The casing can be opened by press-
ing the pegs (10) and (11) inwards one after another using
a screwdriver and applying pressure to lift the casing cover
on the connector side until the pegs release.
To assemble the casing, insert the guides into the casing
shell and press the two halves together using light pressure
until the pegs snap into place.
10. Releasing the isolation amplifi er
The SIRAX TV 808 unit has to be opened before it can be
confi gured (see Section "9. Withdrawing and inserting the
device").

10.1 Type of output signal
(voltage or current)
The output can be confi gured for a voltage or current signal
by inserting the plug-in jumpers "ST 4" or "ST 3" in position
"U" or "I" (Fig. 7).

Current [mA]
10.2 Standard input and output ranges
Two of six plug-in jumpers B1 to B6 are used for selecting
the standard ranges of the isolating amplifi ers. Providing the
potentiometers "Span" and "Zero" are not moved, changing
the range has no infl uence on amplifi er accuracy.

The default setting of the preferred versions ex stock is
0 ... 20 mA for input and output, i.e. jumpers are inserted
in positions B2 and B5 and jumpers ST 4 and ST 3 are in
position "I".
