GENERAL INFORMATION

FT430/440/450 INSTRUCTIONS

The FT430/440/450 flow computers are microcontrollerbased indicator/transmitters that interface with pulse output flow sensors to compute and display flow rate, flow total, and also generate output signals representing flow. The FT430 and FT450 have one scaled pulse output and one pulse pass through. The FT440 has two scaled pulse outputs.
The FT450 is battery powered while the FT430 may be powered by an external DC power source or an optional internal AC power supply*. The FT440 is a “two-wire” or “loop powered” device, meaning that it is powered by the 4-20 mA loop circuit itself. An optional internal AC power supply* is available for the FT440 with dual 24 and 12VDC outputs to power both the loop and sensors requiring more power than the loop can supply.

Pulse and 4-20mA analog outputs can be used to signal external devices, e.g. certain metering pumps and water treatment controls. Alternatively, one or more pulse outputs can be configured as alarm outputs. These flow computers can be password protected to prevent resetting the total or changing configuration settings.
The FT430/440/450 indicators are available in wall and meter mount configurations. The FT430 and FT440 models can also be panel mounted.
Order the FT440 only if a 4-20mA output signal is a requirement and the FT450 if internal battery power is needed. Otherwise the FT430 can be ordered.
*Internal power supply is available for the wall mount option only.

INSTALLATION

FT430/440/450 INSTRUCTIONS

Wall Mount. To mount an FT430/440/450 indicator to the wall, hold the unit in the desired position, mark the holes in the mounting feet, drill and mount with screws. A meter-mounted indicator can be converted to a wall mount using an adapter mounting kit. Contact distributor for information.
Wall mount housings for FT units are supplied with 3 cord grips of different sizes. Be sure to use the appropriate sized cord grip for your cable or cables and to assure any unused cord grips are well sealed with a properly sized plug (these plugs will come in the cord grips that are supplied with the wall mount housing when shipped from the factory.) There will be a properly sized cord grip for any cable supplied by Seametrics.

Meter Mount. If the FT430/440/450 indicator was ordered as a meter mount model, the housing is already mounted directly to the flow sensor and needs no further installation.
An FT430/440 module can be converted from a wall-mount to an IP meter-mount unit using the mounting kit (contact distributor) that includes a lower housing and associated hardware and installs as follows:
1. Remove the strain relief through which the flow sensor cable runs.
2. Cut the cable to about 6″ in length. Carefully strip the cable jacket to expose the three colored wires (red, white, and black) inside.
3. Route the wires through the threaded connector pre-installed in the bottom of the housing.

4. Start the threaded connector into the female thread
on the top of the flow sensor. Be sure to match the oblong shape on the bottom of the housing to the
depression on the top of the flow sensor.

5. Using an ordinary screwdriver inserted in one side
of the slot (see drawing), tighten the screw as much as possible.

6. Strip the wire ends, make the connections to the indicator as shown in Connections Diagrams, and then use the cover screws to attach the indicator to
the top of the housing.

Cord Grips. Cord grips supplied by Seametrics are properly

sized for the openings and threads in our meters and housings

and are properly sized for cables offered by Seametrics. Cord

grips must be well sealed into their housings and must be

well sealed onto any cable that is installed through that cord

Wall Mount Housings. Wall mount housings for FT units are supplied with 3 cord grips of different sizes. Be sure to use the appropriate sized cord grip for your cable or cables and to assure any unused cord grips are well sealed with a properly sized plug (these plugs will come in the cord grips that are supplied with the wall mount housing when shipped from the factory.) There will be a properly sized cord grip for any cable supplied by Seametrics.

Panel Mount. Using the “Panel Cutout” drawing as a guide, cut a hole in the panel. Place the FT430/440 indicator on the panel and mark the holes, drill, and mount with the supplied screws and washers.
Note: In addition to the panel cut out for the display, you will need a small cut out in the panel, close to the FT430/440, to mount the data logger connector. Install the data logger connector in the small cut out and then wire the connector to the back of the panel mounted FT430/440 inside of the panel.
Connections. To connect the flow computer to a flow sensor or an external device such as a chemical metering pump, follow the Standard Connections diagrams on the following pages.
Environmental protection. Anytime an FT unit, or other meter is opened or otherwise exposed to the surrounding environment it is the responsibility of the installer to assure the housing is left clean, dry, fully sealed and otherwise protected from the surroundings. Moisture and dirt will damage electronics and care must be taken to keep the electronics housings clean and dry.
When installing, or re-installing any FT, or other housing cover to any enclosure be certain the gasket is in good condition, is clean and has not been damaged in any way. Then be certain to snugly torque the fastener(s) so the gasket is well sealed.
Every threaded opening in any meter housing will either be filled with a plug or a cord grip when the unit leaves the factory. If a plug is removed to allow for a cable to be installed, be certain a cord grip with cable gland is installed in its place and that the thread is sealed with a thread sealant or proper O-ring. Bare plastic threads in a metal housing are not

Cables. We recommend the use of cables that are supplied by Seametrics. If other cables are used the outside of the cable must be round and smooth so the cord grip can properly seal the cable.
Keep in mind that most cables are not sealed on the inside and a cable that is well sealed to a housing but left open on the weather end is just a conduit for moisture and changes in atmospheric pressure will cause, over time, moisture to be drawn into the housing through any exposed cable end, causing failure of your electronics.
* EGND – Additional protection against voltage spikes. In most cases, an FT unit can simply be installed with power (or battery) and pulse input and it will easily run with no additional protection required. In the event the FT unit may be exposed to voltage spikes (nearby lightning or other power disruptions), the EGND terminal of the FT should be wired to a good earth ground. In wall mount units with optional power supplies installed, Seametrics recommends running a separate green or green/yellow wire from the EGND terminal of the FT to the G terminal of the AC input voltage plug while that plug is not installed and then reinstall the plug after wiring. In cases where the power supply is located remotely, connect one end of one conductor in the power/output cable to a good earth ground and the other end to the EGND terminal.
For FT units built with firmware revision CP-141xx_01.28 (found in the EXIT tab of the first menu screen,) all settings (K-factor, R UNIT, T UNIT, etc.) must be made with the EGND terminal disconnected. The EGND terminal can then be reconnected after programming.

K-Factor

Menu Navigation

At a minimum, every FT430/440/450 flow computer must be programmed with the “K-factor”. (This is the number of pulses that the meter produces per gallon of flow.) If you wish to read in units other than gallons, see below.
The K-factor on any Seametrics flow sensor fitting or inline meter can be found on the model-serial label. The line reading K = xxxx gives the desired number. For depthadjustable sensors (110, 210, 150, 250 models), use the calculator on our website.
(Refer to the appropriate instruction manuals for iMAG 4700, AG3000 or WMP pulse settings.)
Note: The K-factor on all FT430/440/450 flow computers is expressed in pulses per gallon of flow regardless of rate or total units.

The left/right keys are used to move through the menus and position the cursor during data entry. The up arrow is used to scroll through the available values that are to be entered. (examples: numerical values for K factor entry or selection of units from the available options) The enter key (represented on the keypad by the check mark) is used to save selected entries and in conjunction with the exit tab to move between menu screens. As one navigates the menus the current parameter setting is shown and instructions are displayed for how to change the selected parameter.

Things to try… Check for minimum 12 Vdc at power terminals Disconnect sensor, see if display returns (zero flow rate) Wiggle battery, replace if over three years old Push any button to reactivate display. (Display goes to sleep after about 3 minutes of non-use) Increase Set F to a higher value
Contact distributor for return/replacement Reroute wire or change to shielded wire
See flow sensor manual to check Consult factory for “anti-jitter” setting
Enter correct K-factor from meter, fitting, or manual Change K-factor to pulses per gallon
Enable BURST mode.
Use “Set P” to correct pulse output setting Reverse leads
Use “Set 4” to correct target minimum flow rate Use “Set 20” to correct target top flow rate Check voltage (For 4-20mA applications, 24 Vdc is recommended) Compare to Connections diagram Adjust pulse input or rate unit to display fewer characters Disable REED
Consult flow sensor manual for how to test Check for continuity with multimeter Check flow sensor model for “micropower option”

Display showing meaningless characters
Pulse output values are incorrect

Unit’s microcontroller crashed
Battery nearly dead
External electrical noise disrupting output function

Totalizer does not always appear to display the total flow

Break in power to meter

Disconnect and reconnect power. If problem repeats, contact distributor for return/replacement Replace battery Tie commons together by adding a jumper between pulse out [-] and power [-] and/or EGND
The totalizer’s memory is only updated every 15 minutes. If power is lost, the totalizer will retain the value last written but will not be updated to reflect any flow between the last write and the time the power was lost
