204 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.
617The 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.
