PROFILE
Select desired profile to edit (0 thru F). When a profile is running, the
currently running segment setpoint or time value should not be changed,
however, other segments may be changed.
PROFILE DEVIATION ERROR VALUE
0
to
100.0
Profile process value conformity can be assured by using the profile
Error Value parameter. If the process value deviates outside the error
band (
SP
–

) while a profile is running, the controller enters the delay
mode. In the delay mode, the time base of the profile is held (delayed)
until the process value is within the deviation error band. At this time, the
profile continues running unless the process value again deviates.
These actions ensure that the actual process value conforms to the
profile.
PROFILE DEVIATION ERROR TIME VALUE
0.0
to
999.9
minutes
When the profile enters delay mode due to the process value being
outside the Profile Error Band, a Profile Error timer starts. If the process
value remains outside the error band and the timer exceeds the Error
Time Value, the Profile Error Band Timeout flag,
Pt
, is set. The Alarm
output(s) can be configured to activate based on the
Pt
flag condition.
See 4-AL Alarm Action for more information. The flag (
Pt
) is cleared
when the profile is manually stopped; the profile is manually advanced
to the next segment; the profile is put into run state after being paused;
or when a profile is started. A value of 0 disables Error Band Timeout
Flag operation. See “Error Band Delay Mode Timeout” in the “Profile
Overview” section.
START-UP RAMP RATE
0.1
to
100.0
display units/minute
The Start-up Ramp Rate is used to reduce sudden shock to a process
during setpoint changes and system startup. A start-up ramp rate is used
to move the Target Setpoint at a controlled rate. The value is entered in
display units/minute. If the Ramp Rate is enabled, and the Setpoint
value is changed or the controller is powered up, the controller sets the
Target Setpoint to the current process measurement, and ramps to
setpoint. (In a properly designed and functioning system, the process
will have followed the Target Setpoint value to the Setpoint value.)
