6.8 Setting of active or
passive current out-
put mode
The current output of the transmitter can
operate in either active or passive mode to
make elec-trical connection as easy as
possible. The default current output in the
transmitter is set to passive mode and must
be looped powered.
If an active mode is required, a jumper on the
transmitter PCB must be put in active position.
This is done by taking out the transmitter elec-
tronics, follow the instructions in section
5.2.11 or 5.2.12. Jumper position is shown
below.
Passive mode: Jumper in right position.
Active mode: Jumper in left position.
Be aware that in active mode the output shall be considered as a barrier output. The connection
is not safe when put in active mode and accidentally connected to a barrier intended for use in
passive mode.
