Miller Electric Mfg. Co.

X.XX indicates the firmware revision number installed in the unit.

If an error is detected during the check routine, the system fault LED illuminates and an error message screen appears on the display (see Section 9-5). When the check routine is completed successfully, the operator interface defaults to the following:

S

The Stop

button indicator LED illuminates to indicate no heating cycle is in process.

SThe temperature displays indicate actual temperature from the TC’s (thermocouples). If no thermocouples are connected, the displays indicate OPEN.

SControl LED’s illuminate to indicate the number of control TC’s in the last program.

SThe appropriate degree units (°F or °C) light illuminates.

S The display defaults to the Run Status screen from the last program used and the Run Status

button indicator LED illuminates.

SIf no fault or limit conditions are present, system status lights are not illuminated.


Once set up is complete for the desired program procedure (see Section 6-3), pressing the Run		button will initiate a heating cycle. When a
program run is initiated, the Run	button yellow indicator LED illuminates and the Heat On blue indicator LED illuminates to indicate output is
present to the coil. The cycle will continue until the end of the program is reached or the Stop		button is pressed.

The system has a hold function that will maintain a temperature or hold the soak time of any active temperature controlled program. Pressing the Hold

button will only activate the hold function while in the run mode. If the system is not in the run mode, the following screen will appear on the

display:
