PROTECTION
PROGRAMS: Your programs are protected by an EEPROM memory, which operates without
batteries.
OVERVOLTAGE: The power supply to furnaces with micro-processing units requires perfect
filtering. The ARTIS furnace is protected against over-voltage by a system of active and passive
filters. However, very high over-voltages may interfere with your programs.
As a precautionary measure, we recommend that you keep a record of your programs in the
notebook provided for that purpose.
"WATCHDOG": A separate circuit continually monitors microprocessor operation. In the event
of a malfunction, it switches the unit to safeguard status.
OUTLET VOLTAGE VARIATION: Within a limit of ± 20 volts, the furnace self-corrects the
variation and maintains the same accuracy.
INTERRUPTION OF POWER SUPPLY: If the power supply is cut off, the cycle stops but will
begin again at the same point once the mains voltage is re-established.
Depending on the length of the interruption, the operator will decide whether to continue or cancel
the cycle.
