6 Analogue Outputs
This Chapter deals with the analogue output settings. The FMC 671 Z/676 Z transmitter
is designed for continuous measurement at channel 1 with control of:
• one voltage output 0/2 ... 10 V
• one current output 0/4 ... 20 mA
by the level or volume indication at V0H0. Table 6.1 and Fig. 6.1 summarize the
parameters which control the analog outputs and 10-step LCD display.
When the Silometer is used for limit switching alone, operating mode 2, the analogue
output cannot be used.
UnitsThe analog output signals are based on the measured value displayed in matrix field
V0H0!
Matrix Significance Default value
V0H3 Analogue range
0 = 0...20 mA / 0...10 V
1 = 4...20 mA / 2...10 V
0
V0H4 Output damping in seconds 1
V0H5 0/4 mA value (in units used for calibration or linearization) 0.0
V0H6 20 mA value (in units used for calibration or linearization) 100.0
V0H7 Output on fault condition
0 = –10%
1 = +110 %
2 = hold
0
