Notes on the programmer
Programmer sequence
Times Legend
time (50 Hz) in seconds
31.5............t1
Pre-ventilation time with air damper open
3.................t2
Safety time
- .................t2'
Safety time or safety time with burners that use pilot burners
6.................t3
Short pre-ignition time (ignition transformer on terminal 16)
- .................t3'
Long pre-ignition time (ignition transformer on terminal 15)
12...............t4
Time between beginning of t2' and valve consensus on terminal 19 with t2
- .................t4'
Time between beginning of t2' and valve consensus on terminal 19
12...............t5
Time between end of t4 and consensus at power regulator or at valve on terminal 20
18...............t6
Post-ventilation time (with M2)
3.................t7
Time between consensus for start-up and voltage at terminal 7 (start delay for fan motor M2)
72...............t8
Start-up duration (without t11 and t12)
3.................t9
Second safety time for burners that use pilot burners
12...............t10
Time from start-up to beginning of air pressure control without air damper travel time
t11
Air damper opening travel time
t12 Air damper in flow flame position (MIN) travel time
18...............t13
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%.
