3.3 Troubleshooting for LTX R10 SSI
Troubleshooting describes common problems that may occur when installing the EZ-track and offers possible solutions
to these problems. If, after reading this appendix, you are unable to resolve a problem, contact our application support
department at 1-800-544-7769.
General Checks
Make sure that the magnet is located within the EZ-track’s active stroke area. Magnet assemblies should be positioned so that
they can move freely over the entire area of the active stroke without binding or pushing on the rod.
NOTE:
Ferromagnetic material (material readily magnetized) should be located no closer than 0.25” from the sensing surface of the
EZ-track. This includes mounting brackets, magnet spacers, magnet brackets, and mounting screws. Ferromagnetic mate-
rial can distort the magnetic field, causing adverse operation or failure of the EZ-track.
Check all EZ-track wires for continuity and/or shorts. It is preferable that the cable between the EZ-track and the interface
device be one continuous run. If you are using a junction box, it is highly recommended that the splice junction box be free
of AC and/or DC transient-producing lines. The shield should be carried through the splice and terminated at the interface
device end.
Power Supply Check
This will help you to determine if your power supply is adequate for the EZ-track to operate properly, or if the EZ-track’s cable
has a short or open.
In order for the LTX R10 SSI to operate properly, the external power supply must provide a voltage level between 7 to 30 VDC.
A power supply providing voltage above this specified range may damage the EZ-track. A power supply providing power
below this specified range will not be sufficient to power the EZ-track. When powering more than one LTX R10 SSI on a single
power supply, remember that each LTX R10 SSI typically requires 1 watt of power*. The amount of current draw will vary
based on the input voltage, as well as other operating parameters. To approximate the current draw for a particular EZ-track,
divide the EZ-track wattage by the input voltage. For example, 1 watt divided by 24 VDC equals 40mA.
* See Section 3.4 page 15: Specifications for more information on power consumption.
If your EZ-track is not operating properly, the EZ-track’s cable may have an open or short, or the power supply is not supplying
sufficient power. To verify this, perform the following steps:
1. Turn the power supply off.
2. Remove the mating connector from the EZ-track.
3. Turn the power supply on.
4. Using a digital voltmeter, check from the Power Supply Common to the Power on the mating end of the cable
for a level b7 and +30 VDC.
If reading is between 7 and 30 VDC, turn power supply off and go to step 7. If reading is below 7 VDC, either your power
supply is not providing enough power or the EZ-track’s cable possibly has a short/open. Readings of no voltage or minimal
voltage (less than 5 volts) may be due to short/open in the cable. If reading is NOT between 7 and 30 VDC, go to step 5. If
reading is above 30 VDC, adjust power supply or replace.
5. Turn the power supply off.
6. Check the continuity of the individual wires of the cable between the power supply and the EZ-track. Check for continuity
from one end of the cable to the other. Also verify that no shorts exist between pins.
7. Reconnect the mating connector to the EZ-track.
8. Turn power supply on.
9. Using a digital voltmeter, check the power supply’s"+” and"-” terminals for a voltage between 7 and 30 VDC.
Low voltage readings may indicate a power supply with a wattage (current) rating that is too low. (Each EZ-track requires
approximately 1.3 watts). If the cabling checks out in step 6 and your voltage is below 7 VDC, check your power supply cur-
rent rating. If voltage is between 7 to 30 VDC and the EZ-track is still inoperative, contact factory.
