5.5 Parameter Setting Mode
The parameter setting mode is used to set various settings relating to control, to change various alarm settings and also to set the setting
change rate limiter and used/unused channels. Setting items belonging to the parameter setting mode correspond to the multi-memory
area functions and can be stored up to eight memories. Press the SET key for 2 seconds with state of PV/SV monitor mode, SV setting &
CT monitor mode, or setup setting mode to shift to this mode. The UP, DOWN or <R/S key is used to change the numeric value, and the
SET key is used to change the parameter as well as to register the numeric value.

Description of each parameter
Control loop break alarm (LBA)
Monitors measured value variations and also sets the time to detect any abnormal control loop.
Displayed only for when the LBA is selected as alarm 1.
Setting range:
0.1 to 200.0 minutes
OFF: LBA function OFF
Factory set value: 8.0 minutes
•
No setting can be changed when “1 (Lock)” is selected by the lock level 1.
•
We recommend that the set value of LBA be twice the value of the integral time (I).
If the autotuning function is used, the LBA setting time twice as large as the integral time is
automatically set.
Control loop break alarm deadband (LBD)
Set the area of not outputting LBA. Displayed only for when the LBA is selected as alarm 1.
Setting range:
0 to span (0: LBD OFF)

selected as the alarm 1.

Integral time (I)
Set the time of integral action which eliminates the offset occurring in proportional control.
Setting range:
1 to 3600 seconds
OFF (0 second): Integral action OFF (PD action)
Factory set value: 240 seconds
No setting can be changed when “1 (Lock)” is selected by the lock level 1.
