• Remove power to unit before wiring input and
output connections.

• Follow instructions carefully to avoid personal
injury.

Installation

FP90 series transmitters are available in two styles: panel mount and fi eld mount. The panel mount is supplied with the necessary
hardware to install the transmitter. This manual includes complete panel mounting instructions.
Field mounting requires one of two separate mounting kits. The FP90IM integral kit joins the sensor and instrument together into a
single package. The FP90UM Universal kit enables the transmitter to be installed virtually anywhere.
Detailed instructions for integral mounting or other fi eld installation options are included with the FP90IM Integral kit or the
FP90UM Universal kit.

Panel Installation

1. The panel mount transmitter is designed for installation using a 1/4 DIN Punch. For manual panel cutout, an adhesive
template is provided as an installation guide. Recommended clearance on all sides between instruments is 1 inch.

2. Place gasket on instrument, and install in panel.

3. Slide mounting bracket over back of instrument until quick-clips snap into latches on side of instrument.

4. To remove, secure instrument temporarily with tape from front or grip from rear of instrument. DO NOT RELEASE.

Press quick-clips outward and remove.

Caution: Failure to fully open terminal jaws before

removing wire may permanently damage instrument.

Wiring Procedure

1. Remove 0.5 - 0.625 in. (13-16 mm) of insulation from wire
end.

2. Press the orange terminal lever downward with a small
screwdriver to open terminal jaws.

3. Insert exposed (non-insulated) wire end in terminal hole
until it bottoms out.

4. Release orange terminal lever to secure wire in place.
Gently pull on each wire to ensure a good connection.

Maximum cable length is 200 ft. for FP5100, FP5200, FP5300,
FP6000 and any sinusoidal fl ow signal.

Wiring Removal Procedure

1. Press the orange terminal lever downward with a small
screwdriver to open terminal jaws.

2. When fully open, remove wire from terminal.

Wiring Tips:

• Do not route sensor cable in conduit containing AC power

wiring. Electrical noise may interfere with sensor signal.

• Routing sensor cable in grounded metal conduit will help

prevent electrical noise and mechanical damage.

• Seal cable entry points to prevent moisture damage.

• Only one wire should be inserted into a terminal. Splice

double wires outside the terminal.

Open Collector and Relay Outputs

The open collector and relay outputs can be used as a switch that
responds when the fl ow rate moves above or below a setpoint,
or it can be used to generate a pulse that is relative to the fl ow
volume or to the fl ow rate.

Low (Open Collector or Relay output)
Output triggers when the fl ow rate is less than the setpoint.
The output will deenergize when the fl ow rate moves above the
setpoint plus the hysteresis value.

High (Open Collector or Relay output)
Output triggers when the fl ow rate is greater than the setpoint.
The output will deenergize when the fl 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 fl 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 fl uid that passes the
sensor. Set any value from 0.0001 to 99999.

The fi rst two characters set the Flow Rate units of measure. They have no effect on calculations. They
may be any alpha or numeric character, upper or lower case.
The last character sets the Flow rate Timebase. Select S (seconds), M (minutes), H (hours) or D
(days).

This setting tells the transmitter how to convert the input frequency from the fl ow sensor into a fl ow
rate. The K-factor is unique to the sensor model and to the pipe size and schedule. Refer to data in the
sensor manual for the correct value. Limits: 0.0001 to 99999. (The K-factor cannot be set to 0)

This setting identifi es the Totalizer units. It has no effect on any calculation. It serves as a label only.
Each character can be any alpha or numeric selection, upper or lower case.

This setting tells the transmitter how to convert the input frequency from the fl ow sensor into a
volumetric total. It also is used as the basis for the Open Collector pulse mode.
The setting is usually the same as the Flow K-factor, or different by x10 or x100. Limits: 0.0001 to

99999. (The K-factor cannot be set to 0)

Select the minimum and maximum values for the 4-20 mA Current loop output. The FP90 will allow any
values from 0.0000 to 99999.

Select the desired mode of operation for the Open Collector output. Options available are High, Low,
volumetric Pulse, or Frequency. The signal may be disabled if not used.

In Low or High Mode, the Open Collector output will be deactivated when the Flow rate reaches this
value. Be sure to modify this setting if you change the Flow Units.

The Open Collector output will be deactivated at Setpoint ± Hysteresis, depending on High or Low
Setpoint selection. (See details on page 6.)

In Pulse mode, the Open collector output will generate one pulse when this volume of fl ow passes the
sensor. The measurement is based on the Total K-factor. The FP90 will allow any value from 0.0000 to

99999.

In Pulse mode, this setting defi nes the duration of the Open Collector output pulse. The FP90 allows
any value from 0.1 seconds to 999.9 seconds.

In Frequency mode, the Open Collector output will simulate the sensor frequency, divided by this
setting. The FP90 allows any value from ÷1 to ÷254.

Use this “note pad” to record important dates, such as annual recertifi cation or scheduled maintenance.
