11.2 Inspection and Maintenance of the

Converter

The converter does not require routine inspection and maintenance. If the converter does not

work properly, in most cases it probably comes from problems or other causes.
A dirty touchpanel should be wiped off with a soft dry cloth.

11.2.1 Replacing Fuses

The converter incorporates a fuse, as indicated in Figure 11.5. If the fuse blows out, replace it in

the following procedure.

CAUTION

• If a replaced fuse blows out immediately, there may be a problem in the circuit.

Go over the circuit completely to find out why the fuse has blown.

• This fuse is for protecting the main power supply circuit and does not provide overcurrent

protection for the heater temperature control circuit. For overcurrent protection circuitry, refer

to Section 12.1.2.2, Heater Temperature Failure.
