6.10. Firing continuation in the event of a power failure
• In the event of a power failure during the firing, the controller can automatically continue the firing after the power
failure.
• In the event of a power failure during the lead time, the start is delayed by the remaining lead time when the mains
voltage returns.
• In the event of a power failure during the ramp phase, the controller returns to the previously executed ramp.
• In the event of a power failure during the hold phase, the controller goes to the hold temperature at the set heating rate
and then carries out the remaining hold time
