1
Deviation upper- and lower-limit:
This alarm output operates when PV value is higher than
the setting value SV+(AL-H) or lower than the setting value
SV-(AL-L).
2
Deviation upper-limit:
This alarm output operates when PV value is higher than the
setting value SV+(AL-H).
3
Deviation lower-limit:
This alarm output operates when PV value is lower than the
setting value SV-(AL-L).
4
Reverse deviation upper- and lower-limit:
This alarm output operates when PV value is in the range of
the setting value SV+(AL-H) and the setting value SV-(AL-L).
5
Absolute value upper- and lower-limit:
This alarm output operates when PV value is higher than
the setting value AL-H or lower than the setting value AL-L.
6
Absolute value upper-limit:
This alarm output operates when PV value is higher than
the setting value AL-H.
7
Absolute value lower-limit:
This alarm output operates when PV value is lower than
the setting value AL-L.
8
Deviation upper- and lower-limit with standby sequence:
This alarm output operates when PV value reaches set point
(SV value )and the value is higher than the setting value
SV+(AL-H) or lower than the setting value SV-(AL-L).
9
Deviation upper-limit with standby sequence:
This alarm output operates when PV value reaches set point
(SV value) and the reached value is higher than the
setting value SV+(AL-H).
10
Deviation lower-limit with standby sequence:
This alarm output operates when PV value reaches the set
point (SV value) and the reached value is lower than the
setting value SV-(AL-L).
11
Hysteresis upper-limit alarm output:
This alarm output operates if PV value is higher than the
setting value SV+(AL-H). This alarm output is OFF when
PV value is lower than the setting value SV+(AL-L).
12
Hysteresis lower-limit alarm output:
This alarm output operates if PV value is lower than the
setting value SV-(AL-H). This alarm output is OFF when
PV value is higher than the setting value SV-(AL-L).
(Note: AL-H and AL-L include AL1H, AL2H, AL3H and AL1L, AL2L, AL3L)
