Enter Segments
Segment No. Enter the segment number to be configured.
Typ e Select the segment type as described below:
Soak
Maintains the setpoint at a constant value for the duration of the segment. A soak
segment requires the entry of the desired duration in hh:mm:ss.
If the soak segment is the 1st segment in a program the setpoint value will be set as
defined by the SPT Start Condition parameter. For other segments, the setpoint value
will be derived from the end setpoint value of the previous segment.
Ramp Rate
Increases or decreases the setpoint at a linear rate until the desired value is reached. A
Ramp Rate segment requires the user to enter the desired end setpoint and the desired
ramp rate. The ramp rate is entered in engineering units per time period. The time period
is defined by the Ramp Rate Units parameter.
Ramp Time
Increases or decreases the setpoint at a linear rate until the desired value is reached. A
Ramp Time segment requires the user to enter the desired end setpoint and the desired
ramp duration in hh:mm:ss.
Step
Changes the setpoint value from the end value to of the previous segment to a new
value. A Step segment requires the entry of the Step setpoint value.
Wait
Delays the program until a condition has been met as defined by either or both of the
Wait Event digital signals.
Note. Ramp Rate or Ramp Time will be displayed according to the setting of the Ramp
Type parameter in Common Settings (see page 66).
End
Ends the program.
Period Select the soak or ramp period of the segment in hhh:mm:ss.
Note. Only displayed if Segment Type is configured as Soak or Ramp time.
Setpoint Select the required end setpoint value for the segment in engineering units.
Note. Only displayed if the Segment Type is configured as Ramp Rate or Ramp Time.
Ramp Rate Select the required Ramp Rate for the segment.
Note. Only displayed if Segment Type is Ramp Rate.
Wait Events Select the condition under which the Wait segment will delay the program. The segment
will enter a wait condition when the Wait Event digital inputs match the segment wait
condition as defined below.
Event 1
Waits on the event as defined by the Wait Event 1 digital signal.
Event 2
Waits on the event as defined by the Wait Event 2 digital signal.
Event 1 OR 2
Waits on the state of Wait Event 1 OR Wait Event 2.
Event 1 AND 2
Waits on the state of Wait Event 1' AND Wait Event 2.
Note. Displayed only if Segment Type is Wait.
