time. The alarm can also be activated based on volumetric error rather than a percentage error. This is
accomplished via the Blend Check Alarm Volume parameter.
Blend Adjust parameters are the next parameters to be configured.
Adjustments will be made depending on the configuration of these parameters. The controller will always attempt
to keep the blend to within the percentage dictated by the Blend Adjust Deviation Percentage. No attempts at
adjustment will be made until the Blend Adjust Start or Blend Adjust Restart Volumes have passed.
The Blend Adjust Deviation Percentage or the Blend Adjust Deviation Volume must be violated for the period
specified by the Blend Adjust Time, before any adjustments are made.
The Blend Adjust Start and Restart volumes should be set to values less than the values set for the Blend Check
Start and Restart Volumes, respectively.
For detailed parameter descriptions, please refer to the Configuration chapter topic "Preset Setup."
Meter Setup
It will be necessary to configure Meter parameters for each flow meter. Select the appropriate preset and meter.
On the Meter Setup screen, enter the Flow Control Module number that will receive the flow meter input. Valid
choices are 0-31. The FCM number 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
Upstream Solenoid signal. Port 3 will be used for the control valve's Downstream Solenoid signal.
