AUTOMATIC MODE OPERATIONAL STATES
STATE DISPLAY DESCRIPTION
STOPPED STOPPED
In the STOPPED state, the system closes all valves and acvates the ALARM output.
If ON DEMAND is disabled and the user iniates the system by pressing and holding
the OK buon for a second or more, the system will transion to the START-UP state.
If ON DEMAND is enabled and the user iniates the system by pressing and holding
the OK buon for a second or more, the system will transion to the IDLE state.
START-UP START-UP
In the START-UP state the system checks the input PS3 (PROOF OF CLOSURE). If the
input is acve then the system transions to the POC FAILURE state, if it is inacve
the system transions to the PRE-PURGE state.
PRE-PURGE PRE-PURGE
In the PRE-PURGE state, the system delays for the PREPURGE TIME before
transioning to the IGNITING state and the IGNITION RETRY(s) are reset. The PRE-
PURGE state is intended to provide me for the system to purge itself of unignited
gas.
IGNITE IGNITE
In the IGNITE state, the system begins ignion, opens the ESD and Pilot valves, and
then connues to ignite for the IGNITION TIME or unl ame is detected. If ame is
detected the system will transion to the ESTABLISHING PILOT state. If the ignion
me expires before ame is detected, then the system will transion to the PURGE
state.
PURGE PURGE
In the PURGE state, the system closes all valves. If there are IGNITITON RETRY(s)
remaining, the system delays for the PURGE TIME before transioning to the IGNITE
state. If there are no IGNITION RETRY(s) remaining, the system transions to the
WAIT state. The PURGE state is intended to provide me for the system to purge
itself of unignited gas.
WAIT WAIT
In the WAIT state, the system closes all valves. If there are WAIT RETRY(s) remaining,
the system delays for the WAIT TIME before transioning to the PRE-PURGE state. If
there are no WAIT RETRY(s) remaining, the system transions to the PILOT FAILURE
state.
ESTABLISH
PILOT
EST PILOT
In the EST PILOT state, the system checks for the connuous presence of ame for
the PILOT EST TIME. If the ame is connuously present for the PILOT EST TIME, the
system transions to the PILOT ON state. If ame is lost during the PILOT EST TIME,
the system resets the IGNITION RETRY(s) and transions to the IGNITION state.
PILOT ON PILOT ON
In the PILOT ON state, the system will wait to transion to an ACTIVE state unl one
of the processes becomes acve. If ame is lost in the PILOT ON state, the system
resets the IGNITION RETRY(s) and transions to the IGNITION state.
IDLE IDLE
In the IDLE state, the system closes all valves and waits indenitely unl a process
becomes acve. If a process becomes acve, the system will transion to the START-
UP state.
ACTIVE 1 ACTIVE PRCS 1
In any of the ACTIVE states, the system connually checks the state of all processes.
If a process becomes acve, the system will open the process’ valve and update
the state name accordingly. If any process becomes inacve, the system will close
that process’ valve and update the state name accordingly. If all processes become
inacve, the system will transion back to the PILOT ON state if ON DEMAND is
disabled or to the IDLE state of ON DEMAND is enabled.
