Times Legend
t
ime (50 Hz) in seconds
Pre-ventilation time with air damper open
3.5............t1
Safety time
3.................t2
Safety time or safety time with burners that use pilot burners
- .................t2'
6.................t3
Short pre-ignition time (ignition transformer on terminal 6)
- .................t3'
Long pre-ignition time (ignition transformer on terminal 5)
Time between beginning of t2' and valve consensus on terminal 19 with t2
2...............t4
Time between beginning of t2' and valve consensus on terminal 19
- .................t4'
Time between end of t4 and consensus at power regulator or at valve on terminal 20
2...............t5
Post-ventilation time (with M2)
8...............t6
Time between consensus for start-up and voltage at terminal 7 (start delay for fan motor M2)
3.................t7
Start-up duration (without t11 and t12)
72...............t8
Second safety time for burners that use pilot burners
3.................t9
2...............t10 Time from start-up to beginning of air pressure control without air damper travel time
t
Air damper opening travel time
t12 Air damper in flow flame position (MIN) travel time
8...............t3
Permitted post-combustion time
6.................t16 Initial delay of consensus for air damper OPENING
27...............t20
Time up to automatic closure of programmer mechanism after burner start-up
NOTE: With voltages at 60 Hz, the times are reduced by about 20%.
