Max gas flow in m3/sec
Max gas flow is the maximum flow rate at which the
flow input reaches full scale span.
To set the max gas flow,
figure 34,
press and release
the
Select
key. The value entry will begin to flash
when selected. Use the
Up Arrow
key to increase the
value and the
Down Arrow
key to decrease the value.
When a new value has been chosen, press the
Enter
key to store the new value into memory. The entered
value will stop flashing when it has been loaded into
the memory. Press the
Down Arrow
key to advance
to the next parameter.
Low Flow Shutoff
The low flow shut off setting,
allows a preset
point in a percentage of max gas flow desired to the
N-300G to stop injecting odorant. This allows the
controller to sense low flow conditions where the
operation is not desired. This setting will override the
max time /stroke setting parameter. When flow again
increases above the preset point the N-300G resumes
operation.
To set the low flow shut off,
figure 35,
press and
release the
Select
key. The value entry will begin
to flash when selected. Use the
Up Arrow
key to
increase the value and the
Down Arrow
key to de-
crease the value. When a new value has been cho-
sen, press the
Enter
key to store the new value into
memory. The entered value will stop flashing when it
has been loaded into the memory. Press the
Down
Arrow
key to advance to the next parameter.
Flow (no signal)
The flow
(no signal)
input setting
, is the predeter-
mined percentage of max gas flow that the operator
would like the controller to default to in the event that
the actual flow input signal is lost.
Note:
the
Flow (no signal) input
functions will only
be active with analog input signals 1-5 VDC and 4-20
mA.
