User may edit all general purpose timers. Generally, global timers
affect engine operation. They also help define an event.
a
a)) B1: All event types can be associated with, and locked out
by, a Bx timer. B1 is the first global timer used for delaying
an event condition detection. The timer starts in a running
State (10 – 13) depending on which have been marked ‘In
Use’. B1 is also known as the “Lockout Timer.”
b
b)) B2: The second global timer used for delaying an event
condition detection. B2 is also known as a secondary
“Lockout Timer.”
c
c)) C: The delay allowing a clear reading before beginning
testing for the arming of Class C events. The default and
typical time for most applications is 2 seconds.
d
d)) S: Users have up to five (5) options to assign additional
special global timers to signals. The Sx timers begin con-
currently with the Bx timers.
e
e)) No Flow: The global delay used for delaying the triggering of
a No Flow event. This global no flow timer is enabled after
B1 expires, and begins timing after any of the no flow transi-
tion times configured in the digital input dialog expires.
ff)) Test: Time given to allow for maintenance testing of end
devices without triggering a fault or shutdown condition.
The timer initiates when switched to test mode.
g
g)) Ignition Off Delay: Time delay before the assigned ignition
output turns off. This is typically used to burn remaining
fuel vapors after the fuel valve is turned off.
h
h)) Ignition On Delay: Time delay before the assigned ignition
output turns on. This is typically used to delay ignition
until engine crank rollover can occur.
ii)) Fuel On Delay: Time delay before the assigned fuel valve
output is turns on. This is typically used to delay fuel until
ignition has been turned on.
