5.2.4 Adjustable parameters in the program screen
S – Closing time
The closing time controls the duration of the furnace head closing process.
Value range: 00:18–30:00 (mm:ss)
t – Temperature increase rate (for two-stage programs: t
1
)
The temperature increase rate defines by how many degrees per minute the furnace heats up.
Value range °C: 10 – 140 °C/min; Value range °F: 18 – 252 °F/min
T – Holding temperature (for two-stage programs: T
1
)
The holding temperature defines the temperature at which a firing process is conducted.
Value range °C: 100 – 1200 °C; Value range °F: 212 – 2192°F
H – Holding time (for two-stage programs: H
1
)
The holding time indicates how long an object is fired at the holding temperature.
Value range: 00:00 – 60:00 (mm:ss)
Vacuum on (for two-stage programs: V1
1
)
The parameter defines the temperature at which the vacuum is activated.
Value range °C: OFF or 1 – 1200 °C; Value range °F: 0 or 34 – 2192 °F
Vacuum off (for two-stage programs: V2
1
)
The parameter defines the temperature at which the vacuum is deactivated.
• Holding time without vacuum: If V2 is set one degree lower than the holding temperature, the vacuum is
ended before the holding time.
• Holding time with vacuum: If V2 corresponds to the holding temperature, the vacuum is maintained
during the entire holding time.
• Long-term cooling with vacuum: If V2 is set one degree higher than the holding temperature, the
vacuum is maintained during long-term cooling.
Value range °C: OFF or 1 – 1200 °C; Value range °F: 0 or 34 – 2192 °F
Long-term cooling
If long-term cooling is activated, the furnace cools to the set temperature (L) at the end of the holding
time with the furnace head closed.
Value range °C: OFF or 50 – 1200 °C; Value range °F: 0 or 122 – 2192 °F
Cooling rate
Can only be set if long-term cooling “L” is activated. The cooling rate defines by how many degrees per
minute the furnace cools down.
Value range °C: Off or 1 – 50 °C/min; Value range °F: Off or 2 – 90 °F/min
t2 – Temperature increase rate Stage 2
This parameter defines for the second temperature level by how many degrees per minute the furnace
heats up.
Value range °C: 10 –140 °C/min; Value range °F: 18 – 252°F/min
T2 – Holding temperature Stage 2
The holding temperature for the second temperature level defines the temperature at which a firing
process is conducted.
Value range °C: 100 – 1200 °C; Value range °F: 212 – 2192 °F
H2 – Holding time Stage 2
The holding time for the second temperature level indicates how long an object is fired at the holding
temperature.
Value range: 00:00 – 60:00 (mm:ss)
Vacuum on Stage 2
The parameter defines the temperature at which the vacuum for the second temperature level is activated.
Value range °C: OFF or 1 – 1200 °C; Value range °F: 0 or 34 – 2192 °F
Vacuum off Stage 2
The parameter defines the temperature at which the vacuum for the second temperature level is deactivated.
If V2
2
corresponds to the holding temperature, the vacuum is maintained during the entire holding time.
Value range °C: OFF or 1 – 1200 °C; Value range °F: 0 or 34 – 2192 °F
