EAC

Unselected Valve Set-output Values

When the module starts an Ejector Profile advance stroke, it:

sets its unselected outputs to the values listed below

ignores the unselected value of the selected output

uses ramp rates EAC17 - EAC32 to ramp unselected outputs

if

then

the module is commanded to start any of
the four Clamp Open Profiles during an
Ejector Profile advance stroke

the Ejector Profile gives control of all of its
unselected valves to the executing Clamp
Open Profile

the module is commanded to start an
Ejector Profile advance stroke during any of
the four Clamp Open Profiles

the executing Clamp Open Profile
surrenders control of only the

selected

Ejector Profile advance valve

only one of the four Clamp Open Profiles
and an Ejector Profile advance stroke are
run concurrently

all outputs that are unselected in both
profiles are controlled by the executing
Clamp Open Profile

Output Ramp Rates

The module uses the following ramp rates when moving its outputs
from setpoint to setpoint during any Ejector Profile advance stroke
not being executed concurrently with one of the four Clamp Open
Profiles. If the module is executing an Ejector Profile advance
stroke concurrently with one of the four Clamp Open Profiles, the
module will access only the two ramp rates in EAC17 - EAC32 that
pertain to the selected Ejector Profile advance valve.

The module interprets a zero ramp rate entry as a step function ramp
(ramp disable).
