Heater Control for Windows 4-7
Figure 4-6
Figure 4-6 shows the Output dialog box which is used to define the type of output the
controller uses for the heating process and specific parameters for the output type. All
settings in this dialog box are set for each loop in your system at the Asymtek factory prior
to shipping.
The Type of output used most often for the dispensing system heaters is Time Proportioning
(TP). In this Type, the percent output is converted to a percent duty cycle on the
programmed cycle time. The Action sets the control action of the loop. Normally, heat
outputs are set to Reverse and cool outputs are set to Direct.
Heat Output Limit can be used with IR heaters to limit the temperature ramp. This is done to
prevent damaging heated components on the workpiece by ramping the temperature too fast.
