Special features of device version for operation in Ex zone 1

6.3.1

Configuring the current output

For devices designed for use in Ex-zone 1, the current output configuration cannot be subsequently
changed.
The desired configuration for the current output (active/passive) must be specified when the order is
placed.
For the current output version (active/passive), see the identification marking in the device's terminal
box.
If the signal is configured in "active" mode, no external power may be supplied to the current output.
If the signal is configured in "passive" mode, external power must be supplied to the current output, as
with the pressure and temperature transmitters.
6.3.2

Configuring the digital output

For the device version for operation in Ex zone 1, the digital outputs DO1 (51/52) and DO2 (41/42) can
be configured for a connection to a NAMUR switching amplifier. In the default setting, the outputs are
configured with the standard wiring (non-NAMUR).
Devices with PROFIBUS PA only feature the digital output DO2 (41/42).
IMPORTANT (NOTE)!
This does not affect the output ignition protection type. The devices connected to these outputs must
comply with the applicable regulations for explosion protection.
