Instructions for programming and
running a simple ramp and soak:
- Press the “Page Button” until you reach the
program list (ProG LiSt).
- Press the “Scroll Button” to view the various
settings and Verify that they are correct. Use the “Up Arrow (▲) or Down Arrow (▼)” to
modify the preliminary settings.
Below are the recommended preliminary settings for the controller:
- Holdback Type (“Hb”) – “bAnd"
- Holdback Value (“Hb.U”) – 30
- Ramp Units (“rmP.U”) – “SEc”
- Dwell Units (“dwL.U”) – “min”
- Press the “Scroll button”. The upper portion of the display should
read “CYC.n”, if not, continue hitting the “Scroll button until you find
“CYC.n”. This is the number of
times (or cycles) that the program will be repeated. This is normally set to 1.
- Setup the ramp.
- Press the “Scroll button”. The upper portion of the display
should read “SEG.n”. The lower
portion of the display should read “1”.
This allows modification of the first “segment” of the ramp and
soak.
- Press the “Scroll button”. The upper portion of the display
should read “tYPE". There
are 5 types, Ramp (rmP.r, rmP.t), Soak/dwell (dwEll), step (StEP), and
end. Use the “Up Arrow
(▲)/Down Arrow (▼)” to select rmP.r, the linear ramp at a set
rate.
- Press the “Scroll button”. The upper portion of the display
should read “tGt”. This is the
target setpoint. Use the “Up
Arrow (▲)/Down Arrow (▼)” to modify this value.
- Press the “Scroll button”. The upper portion of the display
should read “rAtE". Set the
desired ramp rate. The units are
°C/sec. Note that the ramp units
can be changed (“rmP.U”).
- Setup the soak (dwell) characteristics.
- Press the “Scroll button”. The upper portion of the display
should read “SEG.n”. The lower
portion should be set to 2.
- Press the “Scroll button”. The upper portion of the display
should read “tYPE". Use the
“Up Arrow (▲)/Down Arrow (▼)” to select “dwEll”.
- Press the “Scroll button”. The upper portion of the display
should read “dur”. This is the
duration of the soak (in minutes).
Use the “Up Arrow (▲)/Down Arrow (▼)” to modify this
value.
- End the program.
- Press the “Scroll button”. The upper portion of the display
should read “SEG.n”. The lower
portion should be set to 3.
- Press the “Scroll button”. The upper portion of the display
should read “tYPE". Use the
“Up Arrow (▲)/Down Arrow (▼)” to select “End”.
- Press the “Scroll button”. The upper portion of the display
should read “End.t”. There are
three options here, a continuous soak (“dwEll”), an abrupt end “S OP”,
and reset (“rSET”), which resets the program and runs it again. Use the “Up Arrow (▲)/Down Arrow
(▼)” to modify this value to “S OP”. If you do not choose this, you will have to manually stop
the program once it has been run.
- Press the Run/Hold Button (●).
- The “RUN” light will illuminate. Once the program is complete, it will
flash. Press the Run/Hold Button
(●) and hold it for 2 seconds to stop the program.
