7.3 Special features of the device design for operation in Div. 1
7.3.1 Configuring the current output
On the device design for operation in Div. 1, the configuration of the current output cannot be
changed once set.
The configuration required for the current output (active/passive) must be specified when the
order is placed.
For the correct current output design (active/passive), see the marking contained in the device's
terminal box.
7.3.2 Configuration of the digital outputs
On the device design for operation in Div. 1, the digital outputs DO1 (51/52) and DO2 (41/42)
can be configured for connection to a NAMUR switching amplifier. On leaving the factory, the
device is configured with the standard wiring (non-NAMUR).
Devices with PROFIBUS PA or FOUNDATION Fieldbus only have the digital output
DO2 (41 / 52).
IMPORTANT (NOTE)
The outputs' type of protection remains unaffected by this. The devices connected to these
outputs must conform to the applicable regulations for explosion protection.
The jumpers are located on the backplane in the transmitter housing.

Configure the digital outputs as described:
1. Switch off the supply power and wait at least 20 minutes before the next step.
2. Open the cover safety device (4) and housing cover (1).
3. Loosen screws (3) and pull out transmitter plug-in (2).
4. Insert the jumpers in the required positions.
5. Put the transmitter plug-in (2) back into the housing and retighten the screws (3).
6. Close the housing cover (1) and lock the cover by unscrewing the screw (4).
