BC: Fuel valve output configuration
This sets the way multi-fuels are configured on the MM,
Setting 0, allows the configuration of 4 fuels and switching between them
is possible using changeover relays. Setting 1
allows 2 fuels to be
configured with each fuel having
its own set of outputs and switching
between fuels is possible without changeover relays. Setting 2 is similar to
setting 1 but with the possibility of fuel Change on the F
ly (COF). See
section 4 of this guide for the full details.
Fuel curves must be commissioned for each fuel valve output mode. This
option must be set before commissioning the MM.
0
One set of outputs (changeover relays, 4 fuels)
1
Two sets of outputs (no changeover relays, 2 fuels)
2
Two sets of outputs, change on the fly (COF)*

BC: Gas Valve Proving Time
This is the time period for when both gas valves are closed to detect a
change in air pressure for the ‘VPS air proving’ phase, or change in gas
pressure for ‘VPS gas proving’ phase.

BC: Maximum Pressure Change Allowed During VPS
If MM detects a pressure change greater than this value, a lockout will
occur. See parameter 41 for gas pressure display units.

0 mbar – 1340 mbar (value 25 = 2.5 mbar)
0” WG – 537.777” WG (value 25 = (1.003 ”WG)
0 PSI – 19.435 PSI (value 25 = 0.036 PSI)

BC: VPS Valve Opening Time
This is the time period for when the phases when a gas valve is opened –
‘VPS Venting’ for the void to vent to atmosphere and ‘VPS Void to Gas’ for
the void to fill with gas.

BC: Purge Time Units/ NFPA Post-Purge
See option/ parameter 118 for the purge timing. For setting 2,
option/parameter 118 must be set to 15 seconds or higher. During the
NFPA post-purge, all the servomotors will remain in the position they were
in before normal shutdown or lockout. The NFPA post-
purge will occur
under any normal shutdown or lockout at any point in firing.
