Suggested Settings for Brooks Presets using Frequency Line Flush
All Brooks electronic presets send 1:1 product flow signals out in bursts that do not reflect the actual flow
rate of the product. Hence averaging of product pulse frequency is a necessity when using the frequency
method of line flush with a Brook preset.
Short Average 40
Long Average 45%
Decrease
50%
To enable the diagnostic screen press the up arrow and check simultaneously.
The diagnostic screen is only displayed while a truck is loading.
Flush Diagnostic Screen
To disable the diagnostic screen press the up arrow and check simultaneously or cycle injector power.
Instantaneous Product Pulse Frequency (Inst)
- This is the instantaneous frequency of the
product pulses (Pluses per second).
Average Product Pulse Frequency (Aver)
- This is the Short Average frequency.
Example:
If
Flush Start % Decrease
is set to 20%, when average (Aver) is 80% of (Max) average, the injector will
begin to flush.
Maximum Product Pulse Frequency (Max)
- This is the Long Average frequency.
Frequency (Freq)
- This is the percentage of the full flow rate.
Spec
- This is the instantaneous actual additive percentage as a percentage of the product volume.
As the load progresses is number should approach 100 %. With the Preload feature enabled the load spec
will be 150 % high and approach 100 as the load progresses through line flush. With Preload disabled the
% spec will start at 0 and approach 100%. Variations in the % spec are related to the fact that the injector
treats in fixed gallon increments. The
Quantity Alarm % spec
high and low parameters will assure that the
automation system is alerted if a load terminates with an additive to product ratio outside the spec range.
Product Line Flush (PLF)
- This is the amount of product that is included in the line flush. This
number should start at zero and counts up toward the
Product Line Flush Volume
.
