SETPOINT VALUE (SP2) *

Integral action shifts the center point position of the proportional band to
eliminate error in the steady state. The higher the integral time, the slower the
response. The optimal integral time is best determined during PID Tuning. If
time is set to zero, the previous Integral output power value is maintained.
Offset Power can be used to provide Manual Reset.

Typically, the controller is operating with the Setpoint value in the bottom
display. There is no annunciator nor parameter indication for Setpoint in the
Display Loop. The parameter name alternates with the setpoint value in the
Hidden Loop. The Setpoint value can be changed, activated and stored by
pressing the arrow keys. This is the only parameter that can be configured as
read only in the Display Loop, but read/write in the Hidden Loop. It is possible
to store a second Setpoint value that can be selected in the Hidden Loop, by the
F1 key or the user input. Both Setpoint values are limited by the Setpoint Low
and High Limits in Input Module 1-IN .
% OUTPUT POWER *
??
?1?? to 1????
???
The % Output Power is shown with the %PW annunciator. The parameter
name alternates with the % Output Power value in the Hidden Loop. While the
controller is in Automatic Mode, this value is read only. When the controller is
placed in Manual Mode, the value can be changed, activated and stored by
pressing the arrow keys. For more details on % Output Power, see Control
Mode Explanations.
OUTPUT POWER OFFSET
?1?? to 1????
? ???
When the Integral Time is set to zero and the controller is in the Automatic
Mode, this parameter will appear after % Output Power. It is also shown with
the %PW annunciator illuminated. The power offset is used to shift the
proportional band to compensate for errors in the steady state. If Integral Action
is later invoked, the controller will re-calculate the internal integral value to
provide “bumpless” transfer and Output Power Offset will not be necessary.
PROPORTIONAL BAND
? to ???? seconds per repeat

Derivative time helps to stabilize the response, but too high of a derivative
time, coupled with noisy signal processes, may cause the output to fluctuate too
greatly, yielding poor control. Setting the time to zero disables derivative action.
ALARM 1 VALUE
???1 ?
? T16
??? P16
On models with alarms, the value for Alarm 1 can be entered here. The value
is either absolute (absolute alarm types) or relative to the Setpoint value
(deviation and band alarm types.) When Alarm 1 is programmed for ???? or
??n? , this parameter is not available. For more details on alarms, see Alarm
Module 4-AL .
ALARM 2 VALUE
???2 ?
? T16
??? P16
On models with alarms, the value for Alarm 2 can be entered here. The value
is either absolute (absolute alarm types) or relative to the Setpoint value
(deviation and band alarm types.) When Alarm 2 is programmed for ???? or
??n? , this parameter is not available. For more details on alarms, see the Alarm
Module ???? .

(% of full input range)
The proportional band should be set to obtain the best response to a process
disturbance while minimizing overshoot. A proportional band of 0.0% forces
the controller into On/Off Control with its characteristic cycling at Setpoint. For
more information, see Control Mode and PID Tuning Explanations.
