The following describes the thermocouple routing from work to power source. Type K thermocouple wire (two wire) is attached directly to the workpiece using a Thermocouple Attachment Unit (see next section for information on attaching thermocouples). The other end is fitted with a 2-pin type K connector. The 2-pin connector plugs into the 3-pin composite extension cable.
5-15. Attaching Welded Thermocouples Do NOT weld thermocouples while connected to power source. Attach thermocouples using a portable Thermocouple Attachment Unit (TAU). This unit spot welds thermocouple wire directly to the workpiece. This method of thermocouple attachment ensures accurate temperature measurement. Clean (file or grind) any loose scale or rust from the workpiece at the places where the wires will be attached.
5-16. Using Contact Thermocouple Sensors Blanket Contact Thermocouple Sensor (See Product Literature Sheet) The welded thermocouples discussed previously can be used for preheating or stress relieving. Welded thermo- couples are normally used in stress relieving applications because of their accuracy and ability to withstand high temperatures.

Remote Control operates the system from a remote device which energizes or de−energizes output as well as setting the desired output power level as a function of the maximum output power setting in the system setup screen. The run button on the front of the ProHeat 35 is disabled in remote mode.
The only programmable selections are Command power and Run Time. Command can be adjusted to deliver up to 35 KW (based on maximum power selected in the set-up screen) for a period of up to 99 hours, 59 minutes, 59 seconds. Power source operating power, current, voltage, and frequency are shown on the right-hand side of the display.

The Stop button indicator LED illuminates to indicate no heating cycle is in process. The temperature displays indicate actual temperature from the TC’s (thermocouples). If no thermocouples are connected, the displays indicate OPEN. Control LEDs illuminate to indicate the number of control TC’s in the last program. The appropriate degree units (°F or °C) light illuminates.

To make changes to a program while in run mode, press the Hold button and the yellow indicator LED will illuminate, and the Run button yellow indicator LED will turn off. When in hold, the system will maintain the actual temperature of the hottest thermocouple while the program is being changed. Press the Program button and the yellow indicator LED will illuminate.
7-10. System Operating Characteristics The power source delivers a high-frequency alternating current output that energizes the coil creating the magnetic field used to heat the workpiece. The power source output characteristics are a function of the configuration, type and number of coils used as shown in the following table: Table 7-1.
