PART III: OPERATION
TSA1 = primo tempo sicurezza (trasformatore accensione OFF)
Ph42
Ph44
t44 = intervallo 1
Ph50
TSA2 = secondo tempo sicurezza
Ph52
t52 = intervallo 2
Ph60
Funzionamento 1 (stazionario)
t62 = massimo tempo bassa fiamma (funzionamento 2, in preparazione per
Ph62
spegnimento, verso bassa fiamma)
Ph70
t13 = tempo postcombustione
Ph72
Verso posizione postcombustione
Ph74
t8 = tempo postventilazione
Ph80
t80 = tempo evacuazione controllo tenuta valvole
Ph81
t81 = tempo perdita pressione atmosferica, prova atmosferica
Ph82
t82 = test perdita, test riempimento
t83 = tempo perdita pressione gas, test pressione
Ph83
Ph90
Tempo attesa "mancanza gas"
Entering the Parameter levels
By means of a proper use of the keys, it is possible to enter the various level parameters, as shown in the following flow chart:
The burner and consequently the LMV2x.. are factory set; the air and fuel curves as set as well.
Info level
TSA1 = 1st safety time (ignition transformer
OFF)
t42 = preignition time OFF
t44 = interval 1
TSA2 = 2nd safety time
t52 = interval 2
Operation 1 (stationary)
t62 = max. time low-fire (operation 2, prepa-
ring for shutdown, traveling to low-fire)
t13 = afterburn time
Traveling to the postpurge position
t8 = postpurge time
t80 = valve proving test evacuation time
t81 = leakage time test time atmospheric
pressure, atmospheric test
t82 = leakage test filling test, filling
t83 = leakage test time gas pressure, pres
sure test
Gas shortage waiting time
