menu, select “I/O Setup.”
SETUP THE 4 mA TO 20 mA
CURRENT OUTPUTS
Any connection of an active 4 mA to 20
mA analog output of QStar UFM with an
external device that also provides a voltage
at its inputs will cause fatal damage to your
QStar UFM and external device. Before you
interconnect both devices, always verify that
your external recording (PCS) system is set
to passive state.
CAUTION
The outputs of QStar UFM are working in active mode
in factory state. That means that the flow transmitter
provides the required voltage to run the outputs.
The inputs of the external device are connected directly
to QStar UFM.
Outputs are activated (factory setting)
Active 1:
QStar UFM 24VDC
Output passive
Passive 1
QStar UFM 24VDC
Passive 2
QStar UFM 24VDC
The mode (passive or active) of the outputs can be
changed inside the QStar UFM. Always use the factory
setting (active mode). If you need to change the mode,
contact your GPI Customer Service Representative.
