Alarm Outputs

For models equipped with alarms there are two alarm outputs. Each alarm can be programmed for one of nine

different alarm types. To set up the first alarm output, press the

button repeatedly until the parameter

Deviation upper- and lower-limit:

Alarm output activates when PV value is higher than the setting value SV+(AL-H) or

lower than the setting value SV-(AL-L).

Deviation upper limit:

Alarm output activates when PV value is higher than the setting value SV+(AL-H).

Deviation lower limit:

Alarm output activates when PV value is lower than the setting value SV-(AL-L).

Absolute value upper and lower limit:

Alarm output activates when PV value is higher than the setting value AL-H or lower

than the setting value AL-L.

Absolute value upper limit:

Alarm output activates when PV value is higher than the setting value AL-H.

Absolute value lower limit:

Alarm output activates when PV value is lower than the setting value AL-L.

Hysteresis upper limit alarm output:

Alarm output activates when PV value is higher than the setting value SV+(AL-H). The

alarm output turns OFF when the PV value is lower than the setting value SV+(AL-L).

Hysteresis lower limit alarm output:

Alarm output activates when PV value is lower than the setting value SV-(AL-H). The

alarm output turns OFF when the PV value is higher than the setting value SV-(AL-L).

Disconnection Alarm: This alarm output is enabled if the sensor connection is

incorrect or has been disconnected.
