Run Status Screen
Mode.....: Manual	TC5:	77
Power....: 0.0 KW	TC6:	77
Countdown: −−:−−:−−
Status...: Stopped

During active operation, Power shows the actual power delivered from the power source, Countdown shows the time remaining in the heating cycle, and Status indicates if the system is running or stopped. TC5 and TC6 display the temperature of thermocouples 5 and 6. This screen is for monitoring purposes only.

.No changes can be made to the run status screen, and the Cursor, Increase and Decrease buttons are not functional.

6-6. Parameters

During active operation, the Parameters screen allows the operator to monitor the power source output operating parameters. These parameters in- clude output power, output amperage, output voltage, and output frequency. In addition, temperatures of thermocouples TC5 and TC6 are also displayed. The Parameters screen is for monitoring purposes only and has no selectable or changeable parameters.

6-7. Cooler

The Cooler button is used to turn the cooler On or Off on systems using liquid-cooled output cables. Systems using liquid-cooled output cables will not deliver output unless the cooler is On. If the cooler is not started prior to initiating a heating cycle, the system will automatically start the

cooler when the Run	button is pressed. Pressing the Stop	button does not shut off the cooler. The cooler must be shut off separately
by pressing the Cooler	button.
When power source output is energized, the cooler cannot be turned off. If the Cooler			button is pressed while output is energized, the follow-

ing screen will appear on the display:
