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
3 inputs are available for 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 transformer output is displayed, not the value of the
primary side. The latter must be determined by the user (transformation ratio of current
converter).
2 measured values per current input are determined:
● RMS over 16 half-waves
● Average value over a control period of 100 half-waves at power output
Supply voltage
4 inputs are available for 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 must
determine the measured line value of the primary side (transformation ratio of current
converter).
2 measured values per phase are determined:
● Measured value over 16 half-waves
● Measured value averaged over a control period of 100 half-waves at the power output
