Operating hours counter
Enable the operating hours counter here. The counting starts from a programmable
minimum current value. The counter can be reset or pre-defined using data record or output
bit.
Enable gate of operating hours counter
Enable the gate for the operating hours counter here. When the gate is activated, the
operating hours counter only counts when the corresponding output data bit (DQ bit) is set to
"1".
Current transformer primary current
Enter here the nominal value for the primary current of the current transformer used. The
transformer ratio is calculated from the primary and secondary current.
Current transformer secondary current
Enter here the nominal value for the secondary current (1 A or 5 A) of the current
transformer used. The transformer ratio is calculated from the primary and secondary
current.
Voltage transformer primary voltage
To determine the voltage transformer ratio, enter the primary voltage here. The transformer
ratio is calculated from the primary and secondary voltage.
Voltage transformer secondary voltage
Enter the secondary voltage to determine the voltage transformer ratio here. The transformer
ratio is calculated from the primary and secondary voltage.
Reverse current direction
Setting to determine whether or not to reverse the direction of current.
In the event of inadvertent incorrect connection, this parameter can be used to correct the
measured values, thus saving the hassle of rewiring. The direction of the current is only
evident from the power measurement values. The current measurement value is an rms
value.
Number of limits
Enter the number of measured values that you want to monitor for limits.
