Program Entry
To Link Programs Together
Push scroll button until "Cnt n" is displayed. Press and release the up and down buttons to switch
between "Cnt y" (continue yes) and "Cnt n" (continue no). The effect of selecting "Cnt y" is to continue
the program to the next program number. For example, if in program #3 you select "Cnt y," when program
#3 is complete, program #4 will run automatically. Setting "Cnt y" in program #4 will initiate the start of
program #1 upon the completion of program #4. Each program will complete the selected number of
loops before continuing (see Loop Count). If you do not want to link programs, set Cnt to "Cnt n"
(continue no).
NOTE
Once the desired parameter has been selected, depressing either the raise or lower button
will cause the parameter to be replaced with the new value. At this point, the "top dot" of the
least significant digit of the secondary display will flash on and off. Any further use of up or
down buttons will change parameter value. In all cases, the value shown on the display is the
current working value of that parameter.
Set Ramp Rates
1. With the programmer not operating, indicated by the bottom right hand side of the display
extinguished, depress scroll button until PR1 is displayed. Push the up or down button to scroll to
the desired value, which is degrees per minute.
Scrolling down below zero will give three other options for the ramp:
NONE-which will force the program to skip to the next segment;
END-which will cause the program to stop or restart if loops remaining is not zero;
STEP-which will cause the program to ramp as quickly as possible to the next temperature level.
All other ramps in the program are set in a similar fashion by selecting 'PR' followed by the relevant ramp
number.
Set Level Temperatures
2. The level to which the first ramp is aiming is entered by scrolling through the main scroll list until "PL1"
is displayed. By pressing either the up or down button the present value of this level is indicated in
display units. Using the up or down button will scroll the present value to the new value required. All
other levels in the program are set in a similar fashion by selecting 'PL' followed by the relevant
number.
Set Dwell Times
3. To set the dwell time for the first level, scroll through the main scroll list until "Pd1" is displayed.
Pressing the up or down button will reveal the current value of time in minutes. Using the up or down
button will scroll the present value to the new value required. Scrolling this value downscale will allow
a setting of "END." A setting of "END" will terminate the program, or force it to restart if loops
remaining are not zero at the beginning of that dwell.
All other dwells in the program can be set in a similar fashion by selecting "PD" followed by the relevant
dwell number.
Set the Number of Times to Repeat the Program
4. Scrolling through the main scroll until the parameter "PLC" is displayed and then depressing the up
or down button will reveal the present setting of the loop count. This is the number of times that the
entered program will be repeated before a continuous setpoint at the last level of the program is
