Temp Control Mode Using Ir Device(S) - Miller 301182 Owner's Manual

6-1-2 Temp Control Mode Using IR Device(s)

.
IR sensors are often designed for a specific temperature and emissivity range. The ProHeat 35 with Operator Interface software revision 1.28
enables temperature control with the Rolling Inductor.
To verify software revision levels, press the Run Status and Parameters buttons simultaneously for 10 seconds to display the software revision.

NOTICE −Damage to workpiece can occur if
temp control is used improperly. Do not use
welded-on or probe style thermocouples in
temp control mode with this device. Always
measure temperature directly after the device
passes over the heating zone.(within 2 inches
of the Rolling Inductor) Keep workpiece or de-
vice in motion while output is on.
NOTICE −Maintain coupling distance of .3125
in (8 mm) to minimize internal heating of
Rolling Inductor.
In this mode, the thermocouple channels are
defined as follows:
TC1
TC2
TC3
TC4
TC5
TC6
If using both TC1 and TC2 for control, the pow-
er source will control based on the hotter of the
two temperature measuring devices.
