During normal operation, the FP90 displays the VIEW menu.
•
When using the CALIBRATE or OPTIONS menus, the FP90 will return to the VIEW menu if no activity occurs for 10 minutes.
•
To select the item you want displayed, press the UP or DOWN arrow keys. The items will scroll in a continuous loop. Changing the

Open Collector and Relay Outputs
The open collector and relay outputs can be used as a switch that
responds when the ow rate moves above or below a setpoint,
or it can be used to generate a pulse that is relative to the ow
volume or to the ow rate.
Low (Open Collector or Relay output)
Output triggers when the ow rate is less than the setpoint.
The output will deenergize when the ow rate moves above the
setpoint plus the hysteresis value.
High (Open Collector or Relay output)
Output triggers when the ow rate is greater than the setpoint.
The output will deenergize when the ow rate drops below the
setpoint plus the hysteresis value.
Frequency (Open Collector only)
Output is a pulse stream that is based on the input ow sensor
signal. The input frequency can be divided by any value from 1 to
254.
Pulse (Open Collector or Relay output)
Output is a pulse based on the volume of uid that passes the
sensor. Set any value from 0.0001 to 99999.
Monitor the Permanent Totalizer value.
Monitor the 4-20 mA Loop output.
Monitor date for scheduled maintenance or date of last calibration.
