Page 11: Running A Program
If not all the segments are used for a program, the Ramp & Dwell of each of the subsequent segments should be set to OFF. A program will end in one of two ways, either revert to the control setpoint or dwell at the temperature set in the last segment used. - Page 12 Working Output Power From the home display, press scroll until the display shows WRK.OP <WORKING OUTPUT POWER>. This shows the power being used as a percentage. Time Remaining Press scroll until the display shows T.REMN <TIME REMAINING>. This shows the dwell time remaining for the current segment.
- Page 13 Program Example The following sequence of entries creates and runs the program shown graphically below. 1. Press scroll until the display shows RAMP.U <SP RAMP UNITS>. Select MIN. 2. Press scroll until the display shows DWELL.U <DWELL UNITS>. Select MIN. 3.
