Information on Energy Pulse Measurement
The binary outputs of the SICAM P may be used to generate impulses for energy measurement:
You can parameterize a specific amount of energy. When this threshold is reached, a defined
pulse will be applied to the output. For energy pulse measurement, you have to adjust several
settings at the device and in the parameterization software.

Parameterization via Device
Refer to chapter 4.4.3.

Pulse Time, Switch Off Time, Number of Pulses
•
Pulse time (
Pulse
): Defines the "high" time of the signal at the binary output; possible values:
50 ms to 500 ms.
•
Switch off time: Time during which the signal at the output of the binary contact is "low". The
switch off time depends on the power measured.
•
Minimum switch off time: The minimum switch off time must not be smaller than 50 ms to
reach a defined switch off time.
•
Number of pulses: The minimum pulse length and the minimum switch off time define the fol-
lowing maximum number of impulses per hour:
