Endress+Hauser prolevel FMC 661, Operating Instructions Manual

Page: 9 / 56

1 Introduction
The Prolevel FMC 661 field transmitter measures level with hydrostatic pressure sensors
or capacitance probes. It may be installed, commissioned and maintained by authorised
personnel only. The operating manual must have been read and understood before the
equipment is installed: instructions are to be followed exactly.
In this manual Since it is not possible to describe all applications in detail, the standard application,
continuous level measurement, has been used as the basis for the functional description.
Other applications as listed in Section 1.1 are described in Chapter 5. The operating
instructions are structured as follows:
•
Chapter 1: Introduction;
contains general information including application, measurement
principle, functional description and technical data.
•
Chapter 2: Installation;
contains hardware configuration, installation instructions and
connection diagrams.
•
Chapter 3: Controls;
describes operation with the front panel keys, Commulog VU 260 Z,
and via the Rackbus RS-485 interface.
•
Chapter 4: Calibration and Operation;
tells you how to commission the Prolevel for the standard
application including calibration, linearisation, analogue outputs,
relays and locking the parameter matrix.
•
Chapter 5: Level Measurement with Limit Switch;
describes the automatic calibration correction and other operating
modes of the Prolevel FMC 661.
•
Chapter 6: Trouble-Shooting;
contains a description of the self-checking system with error
messages, the simulation feature as well as instructions for
configuration on replacement of the transmitter, probe or
electronic insert.
•
Appendix: Contains a flowchart for calibration and linearisation using
volume units.
•
Index: lists key words to help you find information quickly.
Short instructions Short instructions for the standard set-up, continuous level measurement, which is used
in 80% of applications, are to be found in the front cover. We advise you to commission
as described in Section 4.1. before using this procedure as this ensures that probes can
be exchanged without the need for re-calibration.
Further documentation In addition to this manual, the following publications provide information on configuration
of the Prolevel FMC 661.

The installation of the probes, electronic inserts and accessories is described in the
documentation accompanying these articles - see text for references. When installing
probes in explosion hazardous areas the instructions included in the accompanying
probe certification must also be observed.
