Three different differential measurements between two analogue input values can be configured.
Differential measurements between two sensors can be configured in menus 4600-4606. As an example the
figure below shows the two parameters for input selection for differential measurement 1.
Inputs are selected from the input list as shown below, avaible inputs are:
● Multi inputs
● EIC measurements
The relevant alarm setpoint is chosen in parameters 4610-4660. Each alarm can be configured in two alarm
levels for each differential measurement between analog input A and input B. Below figure shows the two pa-
rameters to configure alarm level 1 and 2, for differential measurement 1.
