according to the formulas given below. Increase Xp, if line-out to the set-point
oscillates.
3.7 Alarm handling
Max. three alarms can be configured and assigned to the individual outputs. Ge
-
nerally, outputs OuT.1... OuT.3 can be used each for alarm signalling. If more
than one signal is linked to one output the signals are OR linked. Each of the 3 li
-
mit values Lim.1 … Lim.3 has 2 trigger points H.x (Max) and L.x (Min), which
can be switched off individually (parameter = “OFF”). Switching difference
HYS.x of each limit value is adjustable.
