VDR - Vacuum Chamber Dump Rate
format:
xxxxx
(g/sec.)
function(s):
Learned flow rate of the vacuum chamber dump valve. This parameter will automatically
adjust over time. As it adjusts, retention hopper fills will converge on the targeted fill
weight.
Note: this parameter is typically set to 00000, which means that rate learning does NOT
occur, and vacuum chamber dumps will terminate on low flow or high level (RHH).
Manually setting this parameter to any value other than zero will enable rate learning.
VFT - Vacuum Chamber Fill Time
format:
xxxxx
(seconds)
function(s):
1. When the most significant digit is set to a 0 (0xxxx), this is the maximum allowable
vacuum chamber fill time. Fills are not allowed to go beyond this time.
2. When the most significant digit is set to a 1 (1xxxx), this is the vacuum chamber fill
time. VFR is ignored. Note, however, that a timed fill will terminate prematurely if VCH
is reached.
VDT - Vacuum Chamber Dump Time
format:
xxxxx
(seconds)
function(s):
1. When the most significant digit is set to a 0 (0xxxx), this is the maximum allowable
vacuum chamber dump time. Dumps are not allowed to go beyond this time.
2. When the most significant digit is set to a 1 (1xxxx), this is the vacuum chamber
dump time. VDR is ignored. Note, however, that a timed dump will terminate
prematurely if RHH is reached.
FLA - Fill Lag Time
format:
xxxxx
(milliseconds)
function(s):
Amount of time added to every vacuum chamber fill valve opening. This is to account
for the delay between the controller signaling the opening of the valve and the first
pellets beginning to flow. This can also be considered the minimum vacuum chamber fill
valve open time.
DLA - Dump Lag Time
format:
xxxxx
(milliseconds)
function(s):
Amount of time added to every vacuum chamber dump valve opening. This is to
account for the delay between the controller signaling the opening of the valve and the
first pellets beginning to flow. This can also be considered the minimum vacuum
chamber dump valve open time.
