4.26.2.3 General information about the module
4.26.2.3.1 X20CM4810 settling time
The input high-pass cut-off frequency of the AC voltage input (limit frequency of 34 MHz) means that a certain
amount of settling time is required after changing the DC offset of the pending signal.
• Settling time of approximately 30 seconds at 100 mV/g sensor sensitivity and a 24 V supply voltage with
an accuracy of 0.4 g
• Settling time of approximately 60 seconds at 100 mV/g sensor sensitivity and a 24 V supply voltage with
an accuracy of 0.001 g
• The respective settling time must be allowed to pass in order to achieve accurate measurement results
when an open line occurs. Because of this, all characteristic values and analog input values are set to 0
by the module during the first 30 seconds after a restart or wire breakage.
4.26.2.3.2 Sensor sensitivity
The X20CM4810 always assumes a 100 mV/g acceleration sensor on the input. When using Function model 0 -
Standard, it is possible to configure a different sensor sensitivity directly in the function library.
If a different function model is used, for example an SGC controller or bus coupler, any conversion to a different
sensitivity must be performed manually.
