Setting 1: Feedback Loss Alarm
If the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a "FBL - Feedback
Low" alarm will be displayed and a digital output set for "PID feedback low" (H2-
PID feedback value exceeds the level set to b5-36 for longer than the time set to b5-37, a "FBH - Feedback High" alarm
will be displayed and a digital output set for "PID feedback high" (H2-

range, the alarm and outputs are reset.
Setting 2: Feedback Loss Fault
If the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a "FBL - Feedback
Low" fault will be displayed. If the PID feedback value exceeds the level set to b5-36 for longer than the time set to b5-
37, a "FBH - Feedback High" fault will be displayed. Both events trigger a fault output (H1-

b5-13: PID Feedback Low Detection Level
■
Sets the feedback level used for PID feedback low detection. The PID feedback has to fall below this level for longer
than the time b5-14 before feedback loss is detected.
No.

b5-14: PID Feedback Low Detection Time
■
Sets the time that the PID feedback has to fall below b5-13 before feedback loss is detected.
No.

b5-36: PID Feedback High Detection Level
■
Sets the feedback level used for PID feedback high detection. The PID feedback has to exceed this level for longer than
the time b5-37 before feedback loss is detected.
No.
