Connecting the electronic insert FEI53 (3–WIRE)
The 3-wire DC connection is used in conjunction with the Nivotester switching device FTC325
3–WIRE from Hauser; the switching device's communication signal operates at 3 to 12 V.
The changeover of failsafe mode (MIN) / (MAX) and the level limit calibration take place on the
Nivotester.
Power supply
Supply voltage: 14.5 V DC
Current consumption: < 15 mA
Power consumption: max. 230 mW
Reverse polarity protection: yes
Separation voltage: 0.5 kV
Signal on alarm
Voltage at terminal 3 vis-à-vis terminal 1: < 2.7 V
Connectable load
• Floating relay contacts in the connected switching unit Nivotester FTC325 3-WIRE
• For the contact load capacity, refer to the technical data of the switching device.
Connect the FEI53 (3-WIRE) as follows:
1.
Make the connection as shown in the graphic.
2.
Turn the cable gland until tight.
!
Note!
Do not switch on the supply voltage until you have
familiarized yourself with the device functions as
described on Page 49 "Operation". This will ensure
that you do not accidentally trigger any processes
by switching on the supply voltage.
3.
Switch on the supply voltage.
