15-8 Heaters
Software Setup
When your Century Series dispensing system is shipped from the Asymtek factory, it has specific heater
files saved on the computer hard drive. These heater files have been programmed to fit your particular
dispensing applications. They are attached to the dispensing programs for which they were created.
If you wish to change these heater files or program new heater files, we strongly recommend that you first
contact Asymtek Technical Support.
Testing Heater Loops
You can test your system heaters by turning loops ON and OFF.

NOTE The front doors must be closed or the Interlock turned OFF in order to perform this test.
This test may be performed by an Operator, a Programmer, or an Asymtek service

4. Use the mouse or trackball to position the cursor over the heater icon next to the loop name that
you wish to activate, and double-click on the icon (double-clicking again will deactivate it).

Controller. This is true for both contact and impingement heaters.
