6-1. Power Source/System Setup

.
See power source Owner's Manual for complete instructions on operating the power source.
.
Connect Rolling Inductor to power source before turning it on.
6-1-1 Rolling Inductor—Manual Or Temperature Control Mode
NOTICE −When using a Rolling Inductor, infrared temperature measurement and travel detection are highly recommended. The Rolling Inductor
induces up to 20 kW into a small area, which can quickly heat a part to over 6005 F (3155 C) if it is not moving fast enough. This can damage the
inductor or part. Using the travel detector, the system reduces output as travel speed decreases and disables output when travel stops.
.
The travel detector is a sensitive instrument that can measure travel speeds down to one IPM. Once the part travel is stopped, there is a three
second delay before output can be re-energized.
Vibrations that are present for more than three seconds from sources such as fork lift traffic, trains, grinding, and handling the part can trigger the
sensor, and energize the output.
Always press Stop on the ProHeat front panel when part travel is stopped, to prevent inadvertent heating of the part.
Travel Detection
The Travel Detector can be mounted on the left or right side of the Rolling Inductor. It can also be mounted off of the inductor in a location that
provides a similar travel speed as that of the inductor. A bracket of 3.75 inches long by 2.5 inches wide (96 by 64 mm) will allow for mounting of the
Travel Detector.

Set Rolling Inductor Initial kW to a value between 0.0 and 35.0 kW
S
The Rolling Inductor Initial kW can be increased when working on larger mass parts. It is recommended that the first part is heated with
the kW set to a low value. Observe the maximum kW level that the heat cycle achieves and then set the starting kW to that value or less.
S
Max Output kW can be reduced on smaller mass parts to minimize heat input.
Rolling Inductor Cooler Purge Time: 30−240 seconds
S
The default Rolling Inductor Cooler Purge Time is set to 60 seconds for applications using the 60-foot inductor cables. This can be set
down to 30 seconds for the standard Rolling Inductor with 30-foot cables. The ProHeat automatically doubles the time when two Rolling Inductors
are connected.
