16 Possible Defects and Remedy of Defects
Defect
Failure mode Solution
The material to
be heated is
not heated up Red LED located on the front
panel is flashing:
After the button is pressed
when the coil is not loaded –
incorrect (unsuitable size or
number of coil threads) or
incorrectly connected coil.
Use a standard coil and check correct
connection (that the coil terminals are inserted
enough and bolts are tightened).
Red LED located on the front
panel is flashing:
After the button is pressed
when the heating coil is
inserted to the part to be
heated, or when the heating
coil is being inserted to the
part, or during the heating
process – the overload
protection circuit of the power
supply system was activated.
Make the distance between the material and
the coil larger – e.g. place the coil farther from
the material, or use a bigger coil.
Check where the equipment is connected to the
mains. Power supply from the mains may be
distorted or, supply voltage frequency may be
distorted. The power socket may be connected to
the mains which is supplied by standby source of
power supply (generator), or by DC/AC invertor,
where there is not a sine wave at the output
(there is only square wave or quasi-sine wave), or
the power output is not sufficient!
Connect the equipment to another socket.
Caused by interference by other equipment
connected to the same mains.
Caused by extension cable where the interference
may be induced.
Connect the equipment to another socket.
Check the function of the equipment by pressing
the button when a standard coil is connected
correctly without the heated part inserted.
Yellow LED must be lighting.
The material to
be heated is
heated up
slowly Temperature of the material to
be heated increases too slowly
or not at all. Use a coil the diameter of which is larger by 10
mm than the diameter of material to be heated
is.
Check that the material is ferromagnetic.
Handle wire is
heated up Higher temperature of the
wire can be felt when the wire
is touched.
Check the load time, check that the equipment is
not overloaded. Keep the maximum operation
time of 2 min. and cooling time of 2 min. The
equipment must be controlled by the operator
when cooling down.
The material to
be heated is
not heated up Yellow LED located on the
front panel is flashing. The
equipment is overheated. Let 06434 cool down; while it must be
controlled by the operator.
