Display Refresh Time 

 

 

NOTE

 

From version 2.1xx the refresh rate of the display (cycle time) can be adjusted. 

 

Refresh time 

Display      01s 

Refresh time display 

1 to 5 s 

This parameter determines how often the display is updated/refreshed. This parame-

ter only affects the display. The time configured for this parameter has no effect 

upon interface or analog outputs. 

Measuring Filter 

 

 

NOTE

 

Voltage, current, frequency and power may be monitored though a filter on all control units from ver-

sion 2.1xx on. 
Function: 
A first order digital low pass filter is used to filter noise from the measured values (one measuring pe-

riod is 20 ms at 50 Hz). The time constants of this filter may be adjusted. Different effects are possible 

when the time constraints are adjusted: 

Faster output and display of measuring values

 

If a small time constant is configured, a fast output of measuring values without additional delay due 

to digital filtering is achieved. If the filter is configured to OFF, a direct output without filtering the 

measuring value occurs. 

Settling of the display with oscillating measured value outputs

 

If the measuring value under normal conditions is oscillating causing the displayed value to fluxuate, 

the filter constant may be increased.  This will allow the measured outputs (via analog outputs or inter-

face) to fluxuate less and allow for a display that is steadier. 

 

Measuring filter 

Voltage    0.00s 

Measuring filter voltage 

OFF / 0.04 to 2.56 s 

The measuring intervals of the voltage measuring may be adjusted here. With this 

filter the measuring can be steadied and oscillations during actual value measuring 

can be settled. 

 

Measuring filter 

Current    0.00s 

Measuring filter current 

OFF / 0.04 to 2.56 s 

The measuring intervals of the current measuring may be adjusted here. With this 

filter the measuring can be steadied and oscillations during actual value measuring 

can be settled. 

 

Measuring filter 

Power      0.00s 

Measuring filter power 

OFF / 0.04 to 2.56 s 

The measuring intervals of the power measuring may be adjusted here. With this fil-

ter the measuring can be steadied and oscillations during actual value measuring can 

be settled. 

 

Measuring filter 

Frequency  0.00s 

Measuring filter frequency 

OFF / 0.04 to 2.56 s 

The measuring intervals of the frequency measuring may be adjusted here. With this 

filter the measuring can be steadied and oscillations during actual value measuring 

can be settled.
