13) Actuator position is checked by using one of three methods. The method used depends upon the phase of the sequence.
Position Required to Proceed means that the actuators must achieve and hold a certain position for the sequence to proceed.
Dynamic Position Checking means that the actuator is evaluated by a “time and distance from target” algorithm. The further
the actuator is away from its target position, the less time the actuator is permitted to be in that position. Run ‐ Time Position
Checking means that the actuator is expected to be at a certain point in a certain amount of time (based off of the run ‐ time
of the actuator).
14) For direct spark oil fuel trains, spark (ignition) will occur during prepurge if parameter OilPumpCoupling is set to
Magnetcoupl and parameter IgnOilPumpStart is set to on in Ph22 .
15) If parameter FGR ‐ PS/FCC is set for PSdeactStby , the status of the FGR pressure switch is not checked in phase 10 or 12. The
rest of the sequence is the same as setting this parameter to FGR ‐ PS . If parameter FGR ‐ PS/FCC is set for PS VSD , input X4 ‐
01.3 must be energized anytime the VSD speed is higher than RotSpeed PS on and de ‐ energized anytime the VSD speed is
lower than RotSpeed PS off .
16) Depending on how parameter HeavyOilDirStart is set, input X6 ‐ 01.3 has varying sequences. If this parameter is set for activ
38/44 , input X6 ‐ 01.3 must be energized in phase 44. If this parameter is set for 38/44..62 , input X6 ‐ 01.3 must be energized
in phases 44 ‐ 62. If this parameter is set for act 21..62 , input X6 ‐ 01.3 must be energized in phases 21 ‐ 62. If this parameter is
set for deactivated , energizing input X6 ‐ 01.3 has no effect.
17) Inputs X5 ‐ 03.2 and X5 ‐ 03.3 have many functions depending on how parameter Config X5 ‐ 03 is set. The settings are as
follows:
LMV5x std – If parameter LC_OptgMode is set to ExtLC X5 ‐ 03 , energizing X5 ‐ 03.2 will decrease the firing rate, while
energizing X5 ‐ 03.3 will increase the firing rate.
LMV2/3 std – If parameter LC_OptgMode is set to ExtLC X5 ‐ 03 , energizing X5 ‐ 03.3 will achieve stage 2 oil, while energizing
X5 ‐ 03.2 will achieve stage 3 oil.
LMV2/3 inv – If parameter LC_OptgMode is set to ExtLC X5 ‐ 03 , energizing X5 ‐ 03.2 will achieve stage 2 oil, while energizing
X5 ‐ 03.3 will achieve stage 3 oil.
