Firmware Version 3/4.31.37
After establishing the number of flow meters assigned to the preset, indicate the number of components that will
be delivered through the load arm. Set the Blending Type parameter to SEQ (Sequential Blending). For multiple
meter runs, the Blending Type parameter may also be set to RAT+SEQ if some recipes will be using ratio
delivery.
Low Flow and High Flow rates are established in the Weights & Measures/Preset menu. The Low Flow Start and
Low Flow Restart volumes are also specified on this screen. These parameters define the flow profile.
Parameter
Default Setting
Low Flow Start Volume
50 gallons
Low Flow Restart Volume
15 gallons
Low Flow Rate
150 gallons per minute
High Flow Rate
600 gallons per minute
Meter Setup
The next phase of sequential blending configuration occurs at the Meter level on the Meter setup screen.
Enter the Flow Control Module number that will receive the flow meter input. Valid choices are 0-31. The number
of a FCM is determined by the communication address of the module. The address is determined by the setting
of the DIP switch (S1) that is located on the FCM. The switch position indicates a binary zero when it is in the Off
position; a binary one is represented by a switch in the On position.
The A channel of the flow meter signal will always be on Port 4 of the selected Flow Control Module. If a channel
B signal is used for pulse security that input will always be connected to Port 5. If channel B is not used, Port 5
can be assigned to some other I/O function. Port 2 will automatically be assigned to be the control valve's NO
Solenoid signal. Port 3 will be used for the control valve's NC Solenoid signal.
The Dead Band rates for the flow stages are configured on this screen. No Valve adjustments will be attempted
when the flow rate is within the dead band. Whenever flow drifts outside of the dead band, the valve will make
adjustments to bring the flow rate back within the dead band.
If multiple meters are assigned to the preset, repeat this process for the other meters.
