 The Activation area is used to configure the rules that will be applied to

cause real-time activation of the condition (change from 0 -> 1). For ex-

ample, if you set the following: Voltage RMS 1 (X = V1), Compare to is

set to the configured Nominal voltage (say, V = 230V), Deviation is set

10 (D = 10%) and Operation is set 100*(|X-V|/V) >= D, the condition

will be activated when the RMS voltage of channel 1 goes 10% above or

10% below nominal voltage.

 The Deactivation area is used to configure the rules that will be applied

to cause real-time de-activation of the condition (change from 1 -> 0).

For example, if you set the following: Voltage RMS 1 (X = V1), Com-

pare to is set to the configured Nominal voltage (say, V = 230V), Devia-

tion is set 10 (D = 10%) and Operation is set 100*(|X-V|/V) < D, the

condition will be de-activated when the RMS voltage of channel 1 goes

below 10% deviation from nominal.

 The Compare to list is used to select the type of reference value ("V")

to compare to the X parameter value.

 The Parameter is for setting reference to system parameter such as

nominal voltage value.

 User Value enables the user to edit his own reference value.

 Interval average enables user to compare X to its averaged value over a

defined time interval.

 Value ∆ enables dX/dt (time deviation) operation, which means X is

compared to its previous sample value. For instance, if the selected X

parameter is V1 RMS (from group 10[ms] Fast RMS than V = X[-1]

(meaning, previous 10ms RMS value).

 Deviation defines the Deviation ("D") value used in the operation for-

mula. Notice that some operations do not contain deviation; in such

cases the deviation configuration is not in use.

 Operation defines the rule or mathematical operation to apply for Acti-

vation or Deactivation of condition.
