Endress+Hauser silometer FMC 671 Z - 4 Calibration and Operation; Commissioning of the Transmitter

4 Calibration and Operation
This chapter is concerned with the basic settings of the Silometer FMC 671 Z/676 Z which
allow it to operate for continuous level measurement. The principle sections describe:
• Commissioning of the transmitter
• Empty/full calibration for level measurement
• Empty/full calibration for volume measurement
• Level offset value
• Display of measured values
• Locking the parameter matrix.
The linearization for volume or weight measurements is described in Chapter 5, the
setting of the analogue outputs and relays in Chapter 6 and 7.
Note!
• When configuring note your parameters in the Table in the rear cover.
• If the transmitter is ever replaced, these parameters can be entered at the front
panel, with the FMC 671 Z, Commulog VU 260 Z or via the ZA 67… Gateway.
For level measurements, the transmitter will then measure correctly without the need
for another calibration, see Section 9.3.
4.1 Commissioning of the transmitter
If programming the module for the first time, reset the module to the factory based
parameters, see Table in back cover. Then enter the probe constants f
o
and S (∆f). This
ensures that the EC 37 Z/EC 47 Z electronic insert or Deltapilot can be replaced without
the need for recalibration, see Section 9.3.

Operating mode
Now select the operating mode at V8H0:
• 0 = continuous level measurement on channel 1 together with
level limit switching on channel 2, see Chapter 8, Section 8.3
• 1 = continuous level measurement on channel 1, Sections 4.2, 4.3
• 2 = level limit switching on channel 2, see Chapter 8, Sections 8.2
• 5 = measurement with calibration correction, see Chapter 8, Section 8.4
• 6, 7 =simulation channel 1 or 2, see Chapter 9, Section 9.2.
Step Matrix Entry Significance
1 V8H0 e.g. 1 Mode 1, continuous level measurement (default)
2 - »E« Register entry
Note!
• The default settings for the Silometer are for % level measurement in operating
