Creating a New Program or Editing an
Existing Program (4x16 Segment
Programmable Models Only)
The same steps are used when creating a new pro-
gram and editing an existing program with the excep-
tion being that a new program starts with all its seg-
ments set to End in the tYPE parameter. Temporary
changes can be made to these parameters when the
program is in the hold state but permanent changes
must be made in the reset state. Follow the steps
below to create or edit a program.
1. Press the PAGE button until you reach the
program list (ProG LiSt).
2. Press the SCROLL button until display reads,
"PrG.n."
3. Press the UP or DOWN button to select a
number for a new program or to edit an exist-
ing program.
Hb: Holdback
Holdback consists of a value and a type. If the meas-
ured value lags behind the setpoint by an undesirable
amount during a ramp or dwell, the holdback feature
can be used to freeze the program at its current state
(the HOLD light will flash). The program will resume
when the error comes within the holdback value.
OFF: holdback is disabled.
Lo (Deviation Low Holdback): holds the program
back when process variable deviates below the set-
point by more than the holdback value.
Hi (Deviation High Holdback): holds the program
back when process variable deviates above the set-
point by more than the holdback value.
