Recording Of Analog Measured Line Values With Pom4220 Highend - Siemens SIPLUS HCS Series Operating Instructions Manual

Functions
9.5 Recording of analog measured line values
Line power
The same applies for the line power as for the line current: The measured value refers to the
output value of the current converter. The user him/herself must determine the measured
line value of the primary side (transformation ratio of current converter).
Two measured values are determined for each phase:
● Measured value averaged over 16 half-waves
● Measured value averaged over one control period of a power output (100 half-waves)
Line frequency
The measured frequency value is available as soon as the phase voltage is connected. This
is not linked to the functionality of the heating control. Further processing must be carried out
by the user.

Recording of analog measured line values with POM4220 Highend

Line voltage
The line voltage measured values are transmitted according to the operating mode.
● For connection types "phase-neutral conductor": Voltage between phase and neutral
conductor
● For connection types "phase-phase": Voltage between phase and phase
Line frequency
Frequency measured value is communicated with one decimal place.
Channel current
The averaged channel output measured values (over 200 half-waves for half-wave control or
100 half-waves for phase angle control) are transmitted.
Channel output
The averaged channel output measured values (over 200 half-waves for half-wave control or
100 half-waves for phase angle control) are transmitted.
For economy circuit, the total output of the star load is transmitted (averaged over
100 half-waves).
Fault current
Fault current is measured and communicated for connection type "2-pin switching".
