Configuring the current output
The factory setting for the current output is 4 ... 20 mA.
For devices without explosion protection or for operation in Zone 2 / Div. 2 the following
is valid:
The signal can be configured in "active" or "passive" mode. The current setting is contained in
the order confirmation.
For devices for operation in Zone 1 / Div. 1 the following is valid:
For devices designed for use in Ex Zone 1 / Div.1, the current output cannot be reconfigured
subsequently. 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.
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 supply to the current output is
required (similar to pressure and temperature transmitters).
