Recording of analog measured line values

Note
For the recording of analog measured line values a PM4000 U/I must be available.
No links of any kind are available to the functionality of the heating control system.
Line current
Three inputs are available for the recording of measured current values. lL1, lL2, and lL3 can
be connected.
The measuring range (current converter output) is adjustable.
The value measured at the current converter output is measured, not the value on the
primary side. The latter must be determined by the user himself (transformation ratio of
current converter).
Two measured values are determined for each current input:
● Measured value averaged over 16 half-waves
● Measured value averaged over one control period of a power output (100 half-waves)
Supply voltage
Four inputs are available for the recording of measured voltage values. It is possible to
connect UL1, UL2, UL3 and N. Measurement can be performed in a star or delta circuit.
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 himself 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)
