FLT93 Installation, Operation and

Troubleshooting Guide

Pre-Installation

A. To get the best results from the instrument, the instrument should be mounted 20 pipe diameters downstream from any valve,

pipe elbow, or other flow disturbance and 10 pipe diameters upstream from any disturbances.

The instrument tag shows the model number, tag number (if noted on the customer’s order), serial number along with other

important safety information. Compare this information with the appropriate pipe installation drawings to verify the instrument

is the correct configuration.

B. Verify the serial numbers on the enclosure(s), flow element and electronics match. The instrument may not work if the

serial numbers do not match. (The remote option has a remote transmitter enclosure (FT) and a local flow element enclo-

sure (FE). The integral option has one enclosure.)

Flow Element Serial Number

Also Showing Flow Arrow.

(Located near the FE enclosure.

It is also on the enclosure tag.)

Electronics Serial Number

(It is also on the transmitter’s (FT) enclosure tag.)

C. Recommended installation/troubleshooting tools are an open-ended wrench to fit the NPT connection, an open-ended wrench

to fit the flanged fitting nuts and bolts, a small flat blade screw driver for manipulating potentiometers, both a medium flat

blade screwdriver and a medium phillips head screwdriver for tightening connections, 3 mm allen wrench for CENELEC

approved instruments, a measuring tape for proper flow element placement, and a DVM for Ohm/Voltage measurements.

Note:

If the instrument is a remote configuration, the serial number on the enclosure tags must match.

The recommended tag number on the local enclosure will have an FE in the tag number. The recommended tag number on the

remote enclosure will have an FT in the tag number. (Tags are specified by the customer, “FE/FT” is a recommended naming

convention.)

FLUID COMPONENTS INTERNATIONAL LLC FLT93 Flow Switch Series Flow Element Installation Install the flow element, with the flow arrow (shown on Page 1) in the direction of media flow. The element should be in the center line of the process pipe or rectangular duct. The flow arrow flat area is to be parallel ±2° with the media flow. If the remote control circuit option is used, the serial number of the flow element must match the serial number of the electronic enclosure.

FLT93 Flow Switch Series FLUID COMPONENTS INTERNATIONAL LLC Wiring the Instrument Caution Only qualified personnel are to wire or test this instrument. The operator assumes all responsibilities for safe practices while wiring or troubleshooting. Alert The instrument contains electrostatic discharge (ESD) sensitive devices. Use standard ESD precautions when handling the control circuit.

Control Circuit Adjustment Locations Level Application Signal Output Flow Application Signal Output Adjustment by Observation (Option 1) Note: The control circuit has two mutually exclusive alarms; they are identified as Alarm No. 1 and Alarm No. 2 and each has a set point adjustment potentiometer and LED indicator.

FLUID COMPONENTS INTERNATIONAL LLC FLT93 Flow Switch Series Detecting Decreasing Flow (low flow alarm) If the status LED is off, turn the set point adjustment potentiometer clockwise until the LED turns on. With the LED on, slowly turn the potentiometer counterclockwise one turn past the point at which the LED just turns off. The potentiometer may have up to one-quarter turn of hysteresis, therefore, if the mark is overshot, the procedure should be repeated.

FLT93 Flow Switch Series FLUID COMPONENTS INTERNATIONAL LLC When using the instrument for both level and temperature applications, the temperature signal can be as much as 50°F (28°C) high when the sensing element is in still air. Turn the heater off for temperature only applications. To turn off the heater remove the heater control jumper from the heater wattage control. The jumper may be stored on the control circuit by plugging it across J12 and J14. Placing the jumper here will not turn on the heater.

FLUID COMPONENTS INTERNATIONAL LLC FLT93 Flow Switch Series Detecting Decreasing Flow (low flow alarm) 1. Stop the process flow and allow the signal to stabilize. 2. Record the no-flow signal. (The no-flow signal should be greater than the normal flow signal.) No-Flow Signal = ________ volts DC 3. Determine the set point by calculating the average of the normal and no-flow output signals. (i.e.; If the normal signal is 2.000 volts and the no-flow signal is 5.

FLT93 Flow Switch Series FLUID COMPONENTS INTERNATIONAL LLC Continue With the Air/Gas Flow Procedure 1. Slide the mode switch to the RUN position. 2. Establish the normal process flow condition. For low-flow alarm setups, the status LED should be off. For high flow alarm setups, the status LED should be on. 3. Establish the process alarm condition and monitor the voltmeter display. 4.

FLUID COMPONENTS INTERNATIONAL LLC FLT93 Flow Switch Series 11. Determine the set point by calculating the average of the wet and dry output signals. (i.e., If the wet signal is 0.200 volts and the dry signal is 4.000 volts, then the calculated set point would be 2.100 volts.) 12. Record this value. Calculated Set Point = ________ volts DC Note: The calculated set point must be at least 0.015 volts greater than the wet signal and 0.020 volts less than the dry signal to ensure that the alarm will reset.

FLT93 Flow Switch Series FLUID COMPONENTS INTERNATIONAL LLC Troubleshooting If you continue to experience problems with the instrument, see the Troubleshooting Section in the FLT93 Manual, document number 06EN003246. To acquire a manual, call your local FCI Sales Representative. 1. Is the Yellow LED on,off, blinking, or dim? LED ON Although the LED is on, it may appear dim. This is usually caused by the instrument being supplied with 115 Vac and the Input Power Jumper Configuration set to 220 Vac.
