Overview of Flex ProbeThe INCON™ Flex Probes are magnetostrictive measuring probes that provide a high accuracy level measurement for tanks up to 70 feet (21 meters) in height. This probe is ideal for tall tanks or tanks with low overhead clearance where conventional magnetostrictive probes are not an option.Flex Probes are available in lengths from 44” to 840” (2 to 70 feet), and can be ordered in foot (12”) increments.

Unpacking & Handling the Flex ProbeSpecial care should be taken when unpacking and handling the Flex Probe to avoid damaging the probe.

Important: Installation of the Flex Probe requires at least 2 people.

• Do not cut the tie wraps holding the flex probe together before installation.

• Do not bend the top 2 feet of the probe. The top of the probe has electronic components inside of the tube and must remain straight (Figure 1).

Figure 1: Keep Top of Probe Straight

• Always keep the coils parallel. When the tie wraps are removed, do not lift one coil separately from the other coils. Never twist one coil 90º from the other coils. See figure 2.

Figure 2: Do NOT Lift a Coil Singly

• Do not assemble the weight and floats on the flex probe until ready to be installed in the riser. Carry the parts to the top of the tank before assembling. Do not unwrap the flex probe until ready to install.

• Do not twist the probe during installation. Always keep the coils of the probe parallel. “Unroll” it into the tank.

• Do not let the coil become less than 44½" (113 cm) in diameter while uncoiling.

Flex Probe InstallationThe Flex Probe must have a specific amount of clearance from the bottom of the tank to allow for expansion. See table #1 for clearance levels.

There are two methods for mounting the Flex Probe

• Using an adjustable sleeve with a compression fitting to set the correct clearance.

• Using the riser to correctly set the clearance.

Overall Length (inches) Tank Bottom Clearance

47 ~ 144 1"145 ~ 288 2"289 ~ 432 3"433 ~ 600 4"601 ~ 720 5"721 ~ 840 6"

Table 1: Bottom Clearance

• The weight holds the probe straight and functions as a spacer for the water float.

• The water float, product float and tank mounting components are in a separate box.

The customer provides the following process connection:• For Fixed Mounting: A bushing, flange or metal

cover for a 2" NPT opening. The probe has a ¾" NPT connector.

• For Adjustable Mounting: A bushing, flange or metal cover for a 2" NPT opening. The compression fitting has a 1" NPT connector.

1. Cut the tie wrap at the end of the tube with a hole in the plug ONLY. Leave the other tie wraps intact. This will prevent the coil from unwrapping before installation.

Figure 3: Cut Only First Tie Wrap

2. Place the appropriate equipment on the end of the probe in the following order:

a. Height Adjustment Sleeve with Compression Fitting (if used)

A

b. Thread Adapter (1" or ¾")c. Product Floatd. Float Spacer

(For overall length > 288")e. Water Float f. Stainless Steel Weightg. Stainless Steel Pin

3. Hold the weighted end while another person holds the coiled probe. The weight must always hang straight down. DO NOT BEND.

Figure 4: Do NOT Allow Tube to Bend

Figure 5: Use 2 People, Keep Probe Straight4. Feed the weight in a controlled manner while

uncoiling. Do not drop it in or damage to the end of the probe may result. Slowly feed the probe into the riser, cutting the remaining tie wraps, one by one, as you go. Do not cut all of the tie wraps at once. They have been sequentially marked. Start with number 1 at the end of the probe.

For Adjustable Mount installation continue with step 13.5. Thread and tighten the 4"x 1" adapter to the top

of the probe and mount in the riser. Do not lift the probe by the electrical cable.

6. Thread the 1" compression fitting into the 4"x 1" adaptor continuing to support the probe by its body and not the electrical cable.

7. Thread the Adjustable Sleeve on to the probe.8. Gently lower the probe into the tank until it rests on

the bottom. 9. Mark the spot where the Adjustable Sleeve meets

the compression fitting.10. Raise the probe and measure down from the

marked spot the correct clearance distance from Table 1 and make another mark.

11. Lower the probe down until the second mark lines up with the Adjustable Sleeve and tighten the compression fitting finger tight. Then tighten the nut with a wrench an additional 1¼ turns. Figure 6.

Figure 6: Tighten Compression Fitting 1¼ turns After Finger Tight

12. Continue with step 15.13. Use the appropriate riser length to ensure the

proper clearance as define in table 1.14. Thread and tighten the 4"x 3/4" adapter to the top

of the probe and mount in the riser. Do not lift the probe by the electrical cable.

15. Attach a junction box to the top of the probe and proceed to the wiring section.

Flex Probe WiringThe Flex Probe Splice Kit includes 2 electrical connectors for installation inside a junction box. The junction box must be connected to the top on the probe to prevent water intrusion.

1. Install a junction box onto the top of the Flex Probe2. Record the wire speed for programming. This

number is located on a metal tag attached to the probe cable.

3. Use 2 moisture-resistant connectors (provided) for each probe installation.

Note: The wiring that is inserted into the splices does NOT have the insulation cut back (stripped).

4. Insert 2 red wires into two separate openings of the first connector. Make sure the wires are fully inserted and seated at the end of the connector.

5. Insert 2 black wires into two separate openings of the second connector and then insert the 2 shield wires into the remaining opening of the second connector. Make sure the wires are fully inserted and seated at the end of the connector.

6. The white wire inside the probe cable is not used. Do not insert it into any connector. Cut the white wire back flush to the jacket of the probe cable.

7. Use 8" slip-joint pliers to squeeze each connector together (position the plier’s jaws on the connector perpendicular to the wires and drive the black cap down almost flush to the edge of the connector body).

TroubleshootingWhen troubleshooting a probe problem, it is important not to presume any particular cause. Follow the steps outlined below to properly and quickly troubleshoot probes:

Note: Do not start troubleshooting by swapping probes. It may cause confusion in the process of identifying the problem.

Float Missing:1. Check programming of probe for correct number of

floats 2. Look for active High water or Float Missing Alarms

in the run status at the ATG. 3. If possible, have the technician stick the tank and

compare the measurement with the level reported by the ATG.

4. Is the level correct? If not, is the ATG measuring in reverse (the lower the actual product level the higher it reads on the ATG)? Verify the Probe ratio is programmed correctly. If programming is correct it may be a probe issue, continue with the next steps.

5. Check the water level does the ATG list it as float missing? If it is listed as missing, it could be a probe issue, but again continue to troubleshoot.

6. Try to cycle power. If previously noted, check to see if High water alarm or float missing alarm changed from “ACTIVE” to “CLEARED”. If they clear, again this could be a probe issue, but acknowledge and continue to troubleshoot.

7. After completing the above steps, replace the probe.

No Probe, Probe Sync and Unstable Probe (New Install or Replacement Probe)

1. Check Wiring. Ensure that the Red, Black and Shield wires are connected to the correct terminals to the ATG. There should be two connections in the junction box, (refer to figure 8).

(Probe Alarms on Multiple Channels or Only One Probe Connected)

2. Check Main Board Power Supply. There should be approximately 21 VDC loaded (probe connected) and 24 VDC unloaded across the Red and Black terminals of the probe channel in the ATG.

3. Check Field Wiring. Ensure that the voltage is getting to the probe by checking at the junction box splice or quick disconnect pigtail. With the pigtail end facing you, keyslot up, there should be 24 VDC across the two bottom pins. Test field wiring for a short or open.

4. Remake Splice. Cutback and remake the splice connection in the junction box using the approved seal pack and connectors.

5. Try another Probe Channel. Once the field wiring has been checked and the junction box connection remade, try moving the field wiring to another channel.

Listed below are additional steps for troubleshooting the probe. For missing float or incorrect level problems, consider the following actions:

• Pull probe from tank and manually raise and lower floats. Does the ATG accurately report the change in level?

• Are the right number of floats installed on the probe (verify number of floats programming)

• Are the floats installed correctly? Product float on top, closest to the probe head. Water floats have a weighted ballast ring.

• Is the probe shaft clean? If dirty use an abrasive pad to clean the probe shaft.

• Check that wire connections from probe cable to field wiring are good and dry.
