9. MAINTENANCE
WARNING! These use and maintenance instructions are
intended only for staff qualified for the installation and maintenance
of electrical equipment. Maintenance by other persons may cause
damage to the equipment, persons, animals or things.
In the majority of cases it is necessary to remove the fixed guards in
order to carry out repairs and checks. This also renders the voltage cables
accessible.
Before carrying out any maintenance operations check that the
equipment’s feed cable plug is disconnected from the switchboard.
Put the plug in a place where the maintenance operator can easily
ascertain that it has been disconnected during all of the work done
with the guards removed.
9.1. Error indicator
The electronic thermo-regulator can detect various malfunctions, for
details see 5.6.
9.2. Safety thermostat
The safety thermostat intervenes when the temperature in the chamber
goes above 500°C and de-activates the resisters. The safety thermostat is
located on the outside of the switchboard under the conveyor belt.
To correct the error unplug the feed panel and wait for the chamber to
cool down.
Unscrew the cap of the safety thermostat reset button and press the
button. Resetting is not possible until the temperature in the chamber has
fallen below 500°C.
Since the safety thermostat only intervenes where there are serious
malfunctions, carefully check the oven’s working and repair if necessary
before starting up the oven again.
