6.4 Power level selection
The shape, weight, size and internal clearances, all
affect to the time required to heat up a bearing. The
large variety of bearings precludes the possibility of
providing a specific power level setting for each type.
Instead, the following guidelines are provided:
•
In the case of shielded or sealed bearings with
metallic inserts, a LOW POWER mode must be
always selected. Light metallic rings can heat
up much faster than the rest of the component.
This might damage the bearing or the heater
itself due to too high temperatures.
•
In case of very small bearings a LOW POWER
mode must be selected, otherwise the
component heats up faster than what can
be read by the temperature probe, the
component might reach temperatures above
the desired level.
•
Select a low power setting when heating
bearings with a tight internal clearance
(C1 or C2) or preloaded bearings. Slow heating
ensures that the bearing expands evenly,
thereby preventing damage to the bearing.
The low power modes can be selected by
pressing the LOW POWER button. The display
will indicate the power level selected.

7. Safety features
The TMBH 5 is equipped with the following safety
features:
•
Automatic overheating protection of the heater.
The heater has a couple of temperature sensors
to protect itself. In case that the temperature
measured by them is too high, measures are
automatically taken to stop this. For example,
the heater might lower the power or stop. In
any case, the user must monitor the process
since too fast temperature increases might not
be detected on time.
•
Over current protection.
The heater has a built-in fuse.
•
Faulty temperature probe detection.
In Temperature Mode, the heater will give an
error and stop if no temperature increase is
detected.
