PART III: OPERATION

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:

Ph10

t10 = tempo raggiungimento posizione riposo

t10 = home run

Ph12 Pausa

Standby

(stationary)

Ph22

t22 = tempo di salita ventilatore (motore ventilatore = ON,
valvola intercettazione di sicurezza = ON)

t22 = fan ramp up time (fan motor = ON,
safety shutoff valve = ON)

Ph24

Verso posizione preventilazione

Traveling to the prepurge position

Ph30

t1 = tempo preventilazione

t1 = prepurge time

Ph36

Verso posizione accensione

Traveling to the ignition position

Ph38

t3 = tempo preaccensione

t3 = preignition time

Ph40

TSA1 = primo tempo sicurezza (trasformatore accen-
sione ON)

TSA1= 1st safety time (ignition transformer
ON)

Ph42

TSA1 = primo tempo sicurezza (trasformatore accen-
sione OFF)

TSA1 = 1st safety time (ignition transformer
OFF)
t42 = preignition time OFF

Ph44

t44 = intervallo 1

t44 = interval 1

Ph50

TSA2 = secondo tempo sicurezza

TSA2 = 2nd safety time

Ph52

t52 = intervallo 2

t52 = interval 2

Ph60

Funzionamento 1 (stazionario) Operation

(stationary)

Ph62

t62 = massimo tempo bassa fiamma (funzionamento 2, in
preparazione per spegnimento, verso bassa fiamma)

t62 = max. time low-fire (operation 2, prepa-
ring for shutdown, traveling to low-fire)

Ph70

t13 = tempo postcombustione

t13 = afterburn time

Ph72

Verso posizione postcombustione

Traveling to the postpurge position

Ph74

t8 = tempo postventilazione

t8 = postpurge time

Ph80

t80 = tempo evacuazione controllo tenuta valvole

t80 = valve proving test evacuation time

Ph81

t81 = tempo perdita pressione atmosferica, prova atmo-
sferica

t81 = leakage time test time atmospheric
pressure, atmospheric test

Ph82

t82 = test perdita, test riempimento

t82 = leakage test filling test, filling

Ph83

t83 = tempo perdita pressione gas, test pressione

t83 = leakage test time gas pressure, pres
sure test

Ph90

Tempo attesa “mancanza gas”

Gas shortage waiting time
