2.2 Application (SC110D)
The SC110D is a similar version to the
SC110V, but has a temperature control
mechanism integrated into the unit.
Operating the SC110D
■
Place crossbar/yoke through bore of
bearing (using the largest bar that fits).
■
Place crossbar/yoke on top of bearing heater posts - making sure the crossbar/yoke is
fully seated over the locating pins.
■
Plug magnetic probe into the mini plug socket and attach magnetic tip of probe to inner
race of bearing.
■
Turn “On” the large red power switch in center of front side.
■
Select temperature scale (deg C/F) by pressing C/F switch.
■
Press “DISPLAY” switch repeatedly until “SET TEMP” indicator is lit. Use the Up/Down
switches directly below readout to set the target temperature.
■
Press “DISPLAY” switch repeatedly until “SET Time” indicator is lit. Use the Up/Down
switches directly below readout to set length of time that the machine should maintain
the bearing at the target temperature.
■
To view current bearing temperature press “DISPLAY” so that “TEMP” indicator is lit.
■
Press “START/STOP” switch to start heating the bearing.
■
When bearing is up to temperature & ready to install press “START/STOP” to stop the heater.
■
Remove bearing from machine & install immediately. Turn off the large red power
switch. Always turn off the main power switch when not in use and unplug from wall.
2.3 Bearing Heater Operating conditions
Designed to be used in an industrial environment with an ambient temperature of 0°C to
50°C (32°F to 122°F), and an atmospheric humidity of between 5% to 90%. The induction
heater is meant for indoor use only.
2.4 Principle of Operation
Bearing heaters offer a simple value proposition. Heating bearings evenly during
installation and maintenance avoids expensive damage to valuable tools. This is especially
true when compared to past methods of bearing heating (oil baths, torches etc).
The induction heater works in the same way as a transformer. The primary
coil is the heater and the secondary coil is the workpiece. When the heater
is switched on, a high voltage, low alternating current passes through the
numerous windings of the primary coil. This induces a low voltage, high
current in the workpiece acting as the secondary coil. This high current
results in the heating up of the workpiece.
