3.10 Alarm handling
Max. three alarms can be configured and assigned to the individual outputs. Generally,
outputs
OuT.1... OuT.6 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 limit 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.
Ü Operaing principle absolute alarm
L.1 = OFF ¡ Operating principle relative alarm
L.1 = OFF
H.1 = OFF
H.1 = OFF
Normally open: See examples ( ConF / Out.x / O.Act = 0)
Normally closed: The output relay action is inverted ( ConF/ Out.x / O.Act = 1)
The alarm LED always shows the threshold violation on (out of
limits, switching point). If several alarms are used can be
checked at the operating level, which alarm is active
( Ù … r
Lim.1
Ù … Lim.3 )

The variable to be monitored can be selected separately per configuration for each
alarm.
