The following table lists the data entry fields and a description of their purposes. The ranges for these
parameters will vary based on the type of system control parameter used.
PARAMETER DEFINITION RANGE
SEQ NORMAL BANDWIDTH The sequencer load and unload normal 0 - 20 PSID
bandwidth define when normal staging
stops and fast staging begins. If the
difference between the setpoint and
system control parameter is greater than
the bandwidth fast staging is performed.
SEQ CONTROL DEADBAND The sequencer load and unload control 0 - 20 PSID
deadbands define a zone around the
setpoint where no staging action will be
taken.
SEQ NORMAL STAGE DELAY The sequencer normal stage delay is 0 - 99 MIN
used to add or remove stages when the
difference between the system control
parameter and the setpoint is outside
the deadband but within the normal
bandwidth. Entering a zero for the load
or unload normal stage delay time
disables staging under these conditions.
SEQ FAST STAGE DELAY The sequencer fast stage delay is used to 0.1 - 10 MIN
add or remove stages when the difference
between the system control parameter and
the setpoint is outside the normal
bandwidth.
