FRC DFA400 Instruction Manual

Controls and Indicators All controls and indicators are located on the front of the display module. (Refer to Figure 1.) Display During normal operation the 4-digit LED display indicates flow rate. When the display module identification or program access modes are selected, module specific information, program codes, and settings are displayed. (Refer to Programming Section for more information.) MODE Button The MODE button accesses the display module identification mode. It is used with the TOTAL button to input data when in the program ac ...

There are several ways to install paddlewheel type flow sensors. Mounting options include saddle clamps, weldments, pipe tees, and special adapters. Each mount meets a particular plumbing requirement. Flow sensors are interchangeable. It is recommended to check display accuracy if sensors are swapped and calibrated when necessary. The maximum flow sensor pressure is 600 PSI. Flow Sensor Location Locating the flow sensor in the plumbing system is critical. The flow of water at and around the sensor must be laminar, or smooth, to ensure accurate flow rate ...

Display Module Paddlewheel Flow Sensor and Mounting Assembly Cables Display Module The display module is waterproof and has dimensions less than 3 1/4 inches high by 3 1/4 inches wide by 2 inches deep. All controls and indicators are located on the front of the display module. (Refer to Controls and Indicators.) Paddlewheel Flow Sensor The flow sensor provides an input signal to the display module proportional to discharge flow rate. It is mounted in the discharge piping. Placement of the ...

Note: Allow a minimum of 2 inches clearance above the sensor for connector removal/ installation. Note: When the retainer cap is tightened make sure the flow sensor engages the alignment tab and does not rotate. Note: Dimensions are typical and are an aid to determine flow sensor mounting locations.

This function is used when the flow sensor is installed in a difficult plumbing location where flow is not linear. It corrects for nonlinear flow to provide an accurate flow rate display. Select calibration points (up to 9) that are within the most commonly used range. Note: There must be at least a 5% difference between each calibration point. If a selected calibration point is too close to the previous point, an E206 error code shows on the display. 1. Enter code 322. Result: The digital display shows Pt1 (program is ready to se ...
