1
Upper and lower limit alarm actions: When the PV value
exceeds SV + ALM-H or is lower than the SV – ALM-L
value, the corresponding alarm will be generated.
2
Upper limit alarm generation: When the PV value exceeds
the SV + ALM-H value, the corresponding alarm will be
generated.
3
Lower limit alarm generation: When the PV value is lower
than the SV－ALM-L value, the corresponding alarm will be
generated.
4
Absolute value upper and lower limits alarm actions: When
the PV value exceeds ALM-H or is lower than the ALM-L
value, the corresponding alarm will be generated.
5
Absolute value upper limit alarm actions: When the PV
value exceeds the ALM-H value, the corresponding alarm
will be generated.
6
Absolute value lower limit alarm actions: When the PV
value is lower than the ALM-L value, the corresponding
alarm will be generated.
7
Delay upper limit alarm actions: When the PV value
exceeds the SV + ALM-H value, the corresponding alarm
will be generated.
When the PV value is lower than the SV + ALM-L value,
corresponding alarm will cease.
8
Delay lower limit alarm actions: When the PV value is lower
than the SV – ALM-H value, the corresponding alarm will
be generated.
When the PV value is higher than the SV – ALM-L value,
the corresponding alarm will cease.
9
CT1 alarm actions: When the CT1 value is lower than the
ALM-L value or is higher than the ALM-
H value, the
corresponding alarm will be generated.
10
Programmable Soak (maintain heat) action: When the
programmable control is implemented, the corresponding
alarm will be generated when in a Soak state.
11
Programmable Ramp Up action: When the programmable
control is implemented, the corresponding alarm will be
generated when in a Ramp Up state.
12
Programmable Ramp Down action: When the
programmable control is implemented, the corresponding
alarm will be generated when in a Ramp Down state.
13
Programmable Run action: When the programmable
control is implemented, the corresponding alarm will be
generated when in a Run state.
14
Programmable Hold action: When the programmable
control is implemented, the corresponding alarm will be
generated when in a Hold state.
15
Programmable Stop action: When the programmable
