ZFC K03/0522
Risk of electrocution - High voltage!
Make sure, all the leads to the terminals are disconnected from the ZFC and
NEVER connect the mains power supply to the unit when the protection cover
has been removed!

Sensor supply voltage - Switch setting
Terminal 05-06 (R1) / 03-04 (R2); scaled pulse output
SETUP 8 (read chapter 7) determines the pulse output function. The maximum
pulse frequency of this output is 60 Hz. If a relay output option has been supplied,
be sure that the output frequency does not exceed 5Hz or else the life-time of the
relay will be reduced significantly.
Type FT
A passive transistor output is available with this option. Max. driving capacity
300mA@50V DC.
Terminal connections - Pulse output (typical)
Terminal 07-08 analog output (SETUP A):
An analog output signal proportional to the differential flow rate is available as
standard
