The current output in MASS 6000 can operate
in either active or passive mode to make elec-
trical connection as easy as possible. The
current output in MASS 6000 is default set to
active mode.
If a passive mode is required, a jumper on the
converter PCB must be put in passive position.
This is done by taking out the converter elec-
tronics, follow the instructions in chapter 4.3 or
4.4. Jumper position is shown below.
Passive mode: Jumper in left position.
Active mode: Jumper in right position.
Be aware that in active mode the output shall be evaluated as a barrier output. The
connection is not safe when put in active mode and accidental connected to a barrier
intended for use in passive mode.
