Name Description
High alarm (ALH) Displays high alarm set-value.
Low alarm(ALL) Displays low alarm set-value.
Proportional
band (P)
Set when proportional control is
performed. Control becomes ON/OFF
action with P set to “0” .
Anti-reset
windup (ARW)
Prevents overshoot and/or undershoot
caused by integral action effect. It operates
automatically (AUTO) if ARW is set to “0”.
Integral time
(I)
Eliminates offset occurring in proportional
control. Integral action is OFF with this
action set to “0”.
Derivative time
(D)
Prevents ripples by predicting output change
thereby improving control stability. Derivative
action is OFF with this action set to “0”.
Control loop
break alarm
(LBA)
Indicates control loop break alarm setting.
LBA is off if "0" is set.
Proportioning cycle
(C)
Displays control output cycle (sec.).
Hysteresis
(HYS)
Displays hysteresis of set-value for main
output. (ON/OFF control)
Full scale limit
This limits the maximum of retransmission
output.
Under scale
limit
This limits the minimum of retransmission
output.
Set data lock
(LOC)
Turns the set data lock ON/OFF
