• Ensure the unit is sufciently grounded as stated in this bulletin.

• Depressurize and vent systems without Hot-tap valve prior to installation or removal.

• Conrm the Series IEF wetted material is chemically compatible with process media prior to installation and use.

• Do not exceed maximum temperature and pressure specications.

• Wear appropriate personal protective equipment during installation, removal and or service of the unit.

• Altering the product construction in any way may adversely affect product operation and voids warranty.

• Prior to attempting to wire or service the Series IEF disconnect from power.

OPERATING PRINCIPLE

• Per Faraday’s Law of electromagnetic induction, a voltage is induced in a conductor when it passes through a magnetic eld, and the induced voltage will be directly proportional to the velocity of the conductor.

• The Series IEF Flow Transmitter generates pulsating magnetic elds in the probe to induce a voltage into a conductive uid owing through the pipe.

• Electrodes located on the probe measure the induced voltage. Electronics and rmware within the enclosure convert the voltage to velocity and ow rate while using various outputs to convey the data to connected systems (i.e. display devices, data acquisition systems, or BTU meters).

1. To measure the pipe circumference remove any existing insulation at the location where the transmitter will be installed. Wrap the tape measure around the pipe to measure the circumference at the selected location using the 100ths side of the tape. Record this measurement for entering into the unit when the circumference measurement is requested.

It is recommended to use the A-IEF-KIT which includes a setup display A-IEF-DSP, thickness gage UTG and measuring tape

Determining probe insertion depth for models without a display

For models without a display the following formulas allow for calculating the alignment scale value for setting the depth of the probe into the pipe. Also included are wall thickness charts for various pipe materials and sizes.

Pipes < 11 in (< 279 mm) diameter: 7.1625-1/2*D

Where D represents the pipe outer diameter and WT represents the pipe wall thickness, both in inches. Measurement of the outside diameter and wall thickness can be accomplished as described in the previous section, Determining probe insertion depth for models with a display, or similar method. Precise pipe measurements are required for a high performance installation.

Position the alignment scale such that the alignment scale setting is lined-up with the seam of the enclosure as shown in Figure 13. Minor scale marks are in 1/20ths Securely tighten the thumbscrews.

2. To measure the wall thickness of the pipe use the thickness gage UTG. Following the separate directions provided with the UTG gage and record the thickness. This measurement will be needed to enter into the unit after the circumference data is entered.

Printing out conguration values

NETWORK TERMINATION JUMPER

After installation is complete a table of conguration values can be gathered from the transmitter to print out and insert into one of the hanging plastic envelopes for future reference. The housing cover/display needs to be removed for access to the display port to retrieve the table of conguration values. To do so:

1. Unscrew the four captured cover screws using the supplied 3 mm Allen wrench to remove the enclosure cover. Leave the display cable connected to the main unit.

2. Insert a customer supplied mini-USB cable into the USB connector on the bottom side of the display PCB.

3. Connect the other end into a standard USB port in a laptop.

4. The Series IEF transmitter will appear as a standard USB drive on the laptop.

5. The le name with the conguration values is in the format of: serial number.txt. The serial number can be found on the product label on the side of the transmitter.

6. Print out the conguration values and insert into one of the hanging plastic envelopes for future reference

7. Re-attach the housing cover/display by reinserting the four 3 mm screws.

Removing Series IEF Transmitter

1. To remove the transmitter from an installation without a valve depressurize the pipe and skip to step 4. If installed with a valve loosen compression tting (4) and withdraw the transmitter shaft fully through the valve until it stops.

2. Tighten compression tting (4) snug.

3. Close valve (6) via valve handle (7).

4. Remove transmitter by unscrewing process collet (5) from value (6).

CAUTION

occur to the probe ns.

Network Termination Jumper

On the terminal block PCBA there is a jumper, J1 (see Figure 15), that enables or disables a network termination resistor as dened below: When the network jumper is placed in the ON position there is a 120 ohm termination resistor in place. When the network jumper is placed in the OFF position there is no termination resistor in place. Default: OFF

Be sure to support the housing end of the transmitter to prevent it from ipping while unscrewing process collet (5) as damage may

Troubleshooting Guide

STATUS LED

A status blink code is conveyed by the blinking of the status LED (Figure 17) using the following parameters. A blink is dened as the LED is ON for 200ms followed by the LED being OFF for 200ms. If a status code has a tens digit, the tens digit blink code is created and then followed by a 750ms delay OFF time. Then the ones digit blink code is created. After a blink code is displayed, there is an OFF time of 2 sec before the blink code is displayed again. If more than one condition is true, the condition with the highest code will be displayed.

Example: Item 3, Invalid Factory Conguration with a blink code of 11. There would be a state of the LED being ON for 200 msec, then OFF for 200 msec, then OFF for 750 msec, then ON for 200 msec, then OFF for 200 msec followed by off for 2 sec before repeating this sequence.
