8. OPERATION
There are 2 heating methods:
Temperature mode
•
For controlled heating up to the desired
temperature and if you want to make use
of the thermostat feature. This feature
maintains the heated workpiece at the
pre-set temperature for a maximum period
of 5 minutes.
8.1 Heating in temperature mode (default setting)
•
Position the workpiece and sensor (according to chapters 6 & 7.)
•
Switch on the heater. The display shows 100°C. Enter the desired temperature by pressing the '▲' or
'▼' button (by pressing the () button, you can select increments of either 1º or 10º).
•
Press 'START' . The heating starts, you will hear a slight humming sound.
•
The display shows the current temperature of the bearing. Once the pre-set temperature
has been reached, the display blinks and a clear beep is sounded. Unless you press STOP, the
temperature of the bearing is maintained for 5 minutes, thanks to the thermostat feature.
Heating will restart if the temperature drops by 3ºC. Once the pre-set temperature has been
reached again, the induction heater will sound a clear beep.
•
The display blinks during this cycle. After 15 minutes, the induction heater switches off
and sounds a continuous beep. Each time the induction heater stops, it automatically
demagnetises the workpiece.
•
The heating process or thermostat feature can be interrupted by pressing 'STOP' .
18
Time mode
•
Suitable for series production. If the time
needed to reach a certain temperature is
known, the workpiece can be heated in
series with the time mode.
•
In the event of an emergency. If the sensor
is faulty, as a contingency measure, the
workpiece can be heated with the time
mode. The temperature can be measured
with an external thermometer.
•
In incidental cases when workpieces
are too big for the heater, which in
temperature mode would lead to an error
message due to an insufficient increase
in temperature, the time mode may be a
solution. If this is often the case, choose a
bigger heater from the Timken range.
