Measuring capacitance too large (larger than 2000 pF)

613

Simulation switched on

615

The actual calibration at 4 mA produces an initial capacitance 
larger than 350 pF. It cannot be altered further. 
A reset deletes the error message. 

616

The actual calibration at 20 mA produces a total capacitance 
larger than 2000 pF. It cannot be altered further. 
A reset deletes the error message. 

617

The actual calibration produces a difference in capacitance (’span’) of less than 

10 

pF between initial and total capacitance. It cannot be altered further. 

A reset deletes the error message.

618

Process-specific sensitivity too large

620

The current lies outside the permitted range (4.0 ... 20 mA or 
3.8 ... 20 mA). It has no relationship to the measured value.

6.4   Replacing the FEC 12 Electronic Insert

Note!

If you want to transmit the settings of the old electronic insert into a new electronic
insert, then please note the following section.

Removal

Disconnect the power supply cable from the old electronic insert

Loosen the central mounting screw

Remove the electronic insert

Insertion

Plug in the new electronic insert

Screw down the central mounting screw securely

Connect the power cable to the electronic insert

6.5   Transmitting Basic Settings

The recalibration procedure can be dispensed when replacing an electronic insert.
Call up the setting for offset and sensitivity using the handheld terminal, replace the
electronic insert, and then enter both settings in the new electronic insert.

Calling up offset 
and sensitivity

The offset value indicates zero point calibration and is given as the capacitance value
(initial capacitance). The value for sensitivity is the difference between the initial and
total capacitance (’span’) divided by 100.

Note!
