7. The power cable is damaged
8. Source power is abnormal
9. The ground fault switch is closed
8. Check the working power
7. Power cable of heating plate, the
motor of pump and planing tool may
be damaged
8. Electrical components are t affected
9. The higher-up power has not a
ground fault safety device
7. Check the power cables

increasing
7. The temperature controller switch is
8. The sensor （pt100）is abnormal.
The resistance value of4 and 5 of
heating plate socket should be
within 100~183Ω
9. The heating stick inside heating
plate is abnormal. The resistances
between 2and 3 should be
within23Ω. Insulation resistance
between head of heating stick and
outside shell must be more than
1MΩ
4. Should the temperature controller
readings be more than 300℃, which
suggest he sensor may be damaged
or the connection is loosen. Should
the temperature controller indicate
LL, which suggests the sensor have
a short circuit. Should the
temperature controller indicate HH,
which suggests the circuit of sensor
is open.
5. Correct the temperature by button
located on the temperature
controller.

Lose of control
when heating
The red light is shine, but the
temperature still goes up, that is
because the connector is fault or the
joints 7 and 8 can not open when get
the required temperature.
Replace the temperature controller
Planing tool
does not rotate
The limit switch is ineffective or the
mechanical parts of planing tool are
clipped.
Replace the planning tool limit
