Expert Response Compensation (ERC) Percentage
Word Description
EAC05 Minimum Velocity-advance Control ERC Percentage [31] Although error coding allows range of 00000 to 09999, the module limits it
to a minimum of 01000.
EAC06 Minimum Pressure-advance Control ERC Percentage [31] Although error coding allows range of 00000 to 09999, the module limits
it to a minimum of 01000.
EAC07 Open
Watchdog Timer
Word Description
EAC08 Full Profile Watchdog Timer Preset [21] When Module starts the Ejector Profile, it starts an internal Profile Watchdog Timer. It stops
this timer and resets its accumulated value to zero (after reporting total execution time in EPS57) when it completes the profile. It
sets master status bit SYS04-B14 when the accumulated value of this timer equals or exceeds this entry. A zero entry inhibits
SYS04-B14.
