Page 4: Notes On Safety
Notes on Safety Approved usage The electronic insert FEC 12 may be used for level measurement in connection with capacitive Multicap probes only. It has been designed to operate safely in accordance with current technical and safety standards and must be installed by qualified personnel according to the instructions in this manual. -
Page 5: Introduction
A pre-stored linearisation program also allows volumes to be measured in horizontal cylinders. The FEC 12 electronic insert is installed in the housing of the Multicap probe. It can be used for applications in explosion hazardous areas. -

Electronic insert FEC 12 (HART) Installation A load should be connected into the power cable when connecting a handheld Load for handheld terminal. The handheld terminal can now be connected at any point along the power terminal cable for communication with the electronic insert. The size of the load is given in the following table. -

"Online" 3.3 HART Menu Structure All parameters of the FEC 12 can be addressed by the menu structure using the handheld terminal. The following diagram shows the menu structure of the HART protocol for the FEC 12 electronic insert. Each field in the menu structure can be selected using the arrow or numeric keys on the handheld terminal. -

A complete recalibration is not then required (see also Section 6). 4.1 Basic Calibration at the FEC 12 Electronic Insert The following entries are required for basic calibration of the electronic insert: •... - Page 11 Electronic insert FEC 12 (HART) Calibrating Two types of linearisation can be selected: Selecting linearisation • Vessel characteristics as linear • Vessel characteristics as a horizontal cylinder Use the lefthand switch to select whether linearisation is to be carried out at the electronic insert or by the handheld terminal.
- Page 12 Calibrating Electronic insert FEC 12 (HART) Alternative procedure: The level of the vessel must be known as accurately as possible and should be as calibration with the high as possible. A level which is too low reduces the accuracy of the upper point vessel almost full (corresponding to a full vessel).

Two vessel characteristics are available: linear or horizontal cylinder Note! • The switch on the left on the FEC 12 electronic insert must be moved to the left so that linearisation can be carried out remotely with the handheld terminal. - Page 15 Electronic insert FEC 12 (HART) Calibrating The output damping is set in the factory at 1 s and affects the speed at which the Output damping current output responds to a change in level. When there is a sudden jump from empty to full in the vessel, after 1 s the current display reaches 63% or 14.08 mA of...
