Wiring Solicap M FTI55, FTI56
46 Endress+Hauser
4.11 Connecting the electronic insert FEI57S (PFM)
The two-wire DC connection is used in conjunction with one of the following Nivotester switching
devices from Endress+Hauser:
• FTC325 PFM,
• FTC625 PFM (from SW V1.4),
• FTC470Z,
• FTC471Z
The PFM signal is between 17 and 185 Hz.
The changeover of failsafe mode (MIN) / (MAX) and the level limit calibration take place on the
Nivotester.

Connectable load
• Floating relay contacts in the connected switching unit Nivotester FTC325 PFM, FTC625 PFM
(from SW V1.4), FTC470Z, FTC471Z
• For the contact load capacity, refer to the technical data of the switching device.
Supply voltage: 9.5 to 12.5 V DC
Power consumption: < 150 mW
Reverse polarity protection: yes
Separation voltage: 0.5 kV
TI418F52
Frequency: 17 to 185 Hz
Connect the FEI57 (PFM) 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.
