G shows that the ON/
OFF is changed at
this value.
shows that the ON/
OFF is changed at
a point that "1U" is
added to this value.
The event is turned ON when any change in PV corresponding to increase/decrease in MV (Manipulated
variable) is not observed.
This event is used to detect any fault of final control devices.

• Main setting: Change in PV from the point that the MV reaches the upper limit (100%) or lower limit (0%).
• Sub-setting: Range of absolute value of deviation (PV – SP) allowing the event to turn OFF.
• ON delay time: Diagnosis time
• OFF delay time: A period of time from power ON allowing the event to turn OFF.
• The direct action is used for the heat control. The event is turned ON when the increase in PV becomes
• The reverse action is used for the cool control. The event is turned ON when the decrease in PV becomes
• The event is turned OFF regardless of other conditions when the absolute value of the deviation (PV – SP)
• The event is turned OFF regardless of other conditions when a period of time after starting of operation
When setting the ON delay and OFF delay, it is necessary to put in "Multi-function setup".
The default settings of the ON delay and OFF delay before shipment are 0.0s.

smaller than the main setting after the diagnosis time (ON delay time) has elapsed from the time that the MV
had reached the upper limit, or when the decrease in PV becomes smaller than the main setting from the
time that the diagnosis time (ON delay time) has elapsed from the time that the MV had reached the lower limit.

from the time that the power has been turned ON becomes less than the OFF delay time.
However, the event is turned OFF when the absolute value of the deviation is the (sub-setting – hysteresis)
value or less after the absolute value of the deviation has become the sub-setting or more.
