4 Basic Operation
SP Alarms
You can set an SP absolute-value upper-limit or SP absolute-value lower-limit alarm for the set point
(SP).
The alarm point is set in the corresponding alarm value parameter. The Alarm SP Selection
parameter is used to specify the alarm for either the ramp SP or the target SP.
The corresponding alarm hysteresis setting is also valid.
SP absolute-value upper-limit alarm
Example:
ON
OFF
The alarm output is ON while the SP is equal to or
higher than the set value.
MV Alarms
You can set an MV absolute-value upper-limit or MV absolute-value lower-limit alarm for the
manipulated value (MV).
The alarm point is set in the corresponding alarm value parameter. The corresponding alarm
hysteresis setting is also valid.
MV absolute-value upper-limit alarm
Example for Standard Control:
ON
OFF
The alarm output is ON while the MV is equal to or
higher than the set value.
RSP Alarms
You can set an RSP absolute-value upper-limit alarm or RSP absolute-value lower-limit alarm for the
remote SP input.
The alarm point is set in the corresponding alarm value parameter. The corresponding alarm
hysteresis setting is also valid.
RSP absolute-value upper-limit alarm
Example:
ON
OFF
0
The alarm output is ON while the remote SP is equal
to or higher than the set value.
