The relay will be activated when the measured value goes below the set-point value. uP : up/high alarm set-point.

Example: “do” alarm, “SEt”=220 (value of the ON alarm status), hysteresis “HYS”=12 resulting OFF value (end of alarm status): 232 (resulting from 220 +12).

This function allows you to solve two different kinds of problems: • stabilize the value of the instantaneous measurement displayed by LDI35 when the value is not enough stable from the beginning and would not therefore allow either a clear reading on the display or a good control by the alarm set-point (if present);...

NOTE: for a correct working of the filter, the relative coefficient must satisfy the following relationship: 1 Fi.C (Fi.S x 8) 255. Example: in order to display a temperature with a resolution of 0.1 C, set “Lo.E”=-20 C “Lo”=-20.0 C, “Hi.E”=200 C “Hi”=199.9 C.
