If a Aux3 actuator is used, this defines the purge time that the air actuator or VSD is at purge position and
the Aux3 actuator is at home (closed) position. If a Aux3 actuator is not used, this setting has no effect.
Range = 0.2 to 630 sec Def = 0.2 sec Typ = 0.2 sec
If a Aux3 actuator is used, this defines the purge time that the air actuator or VSD is at purge position and
the Aux3 actuator is at purge (open) position. If a Aux3 actuator is not used, this setting has no effect. Range
= 0.2 to 630 sec Def / Typ = 0.2 sec
S
This defines the time the ignition transformer (OUTPUT X4-02.03) is energized before the pilot valve
(OUTPUT X9-01.02) or main valves (for direct spark fuel trains) become energized. Range = 0.2 to 63sec
Def / Typ = 2sec
When LO w Gasp (Light Oil with Gas pilot) is selected, this is the minimum time the oil pump can run
(OUTPUT terminal X6-02.3) before the LMV attempts to light the pilot, (OUTPUT terminal X9-01.2). Time
starts when air actuator reaches the pre-ignition position, phase 22, and will hold in phase 36 until this
parameter times out (if the time setting is sufficiently long). Range = 0 to 63 sec Def / Typ =1 sec
When a fuel train is selected that has a pilot, this setting defines the overlap of the spark (OUTPUT X4-02.3)
and the pilot valve (OUTPUT X9-01.02). After this time expires, spark is de-energized but the PV remains d h il l (OUTPUT X9 01 02) Af
O open if a flame is present. If a flame is not sensed, a lockout occurs. Can be thought of as the first half of
PTFI. (Pilot Trial For Ignition) Shorter times are more safe. Range = 0.2 to 10 sec, 15 sec for oil Def = 3 sec
Typ = 5 sec
When a fuel train is selected that has a pilot, this setting defines the pilot stabilization period. This time
begins after SafteyTme1Gas (Oil) expires. During this period, only the pilot valve is open. The spark is de-
S
energized. Can be thought of as the second half of PTFI.
Range = 0.2 to 63 sec. Def = 2 sec. Typ = 5 sec.
When GP2 gas train is selected, this setting defines the overlap of the PV (pilot OUTPUT X9-01.02) and the
main gas valves, V1 & V2, (OUTPUT X9.01.04 and X9.01.03 respectfully) After this time expires the PV is
de-energized, if continuous pilot is not selected. Can be thought of as the first half of MTFI. When LO w
Gasp oil train is selected, this setting defines the overlap of the PV energized (pilot) and the main oil valves,
O
V1 & V1, (OUTPUT terminals X8.02.01 and X8.03.01) After this time expires, the PV is de-energized, if
continuous pilot is not selected. Most critical safety time other than prepurge. Shorter times are more safe.
Range = 0.2 to 10 sec, 15 sec for oil Def = 3 sec Typ = 5 sec
