YP100 Operating Sequence
Start-Up (Normal Cycle)
Note: For direct spark ignited oil burners, substitute the words Main-Oil Valve for Pilot Valve.
1.
Constant 120 VAC should be available to the Ll-L2 terminals only on the wiring base.
2.
The operating control circuits (Ll-3) will close, signaling the burner to start its firing sequence.
Terminal 13, fuel valve end switch must be closed.
3.
The burner/blower motor (terminal M) circuit is energized. The running interlock (limit) circuit
(3-P) will close (e.g. all limits, interlocks, etc. are proven).
4.
See Figure 2 for sensor wiring.
5.
When the firing rate motor reaches its open damper position, the Hi Purge switch closes (M-8)
and the prepurge interval of 30* seconds is initiated.
Assuming countdown method, the BLV512 will display:
If the M-8 circuit does not close, the program will hold in this position for ten minutes waiting
for it to close. If it does not, the control will lockout. If the M-8 circuit is closed at the start of a
cycle, the top line of a display will switch to PURGE 20 seconds.
