MAG-XL Flex Probe Troubleshooting
The following diagnostics are for the MAG-XL Flex Probe. For wireless troubleshooting and/or additional probe
troubleshooting information, refer to the TLS RF Wireless 2 System (W2) Installation and Maintenance Guide, part
number 577013-964.
Troubleshooting
Use the TLS Console to check the probe height and temperature readings. If the probe is communicating properly
with the console but either the height or temperature are reading 999's, check for the symptoms listed below. If
the Console is receiving data, the product height level is equal to the position of the float on the probe tube. A
level reading error will occur if the offset (Mag Probe Offset) for the probe is incorrect, see the previous
description for making height reading adjustments.
If the probe is installed in an empty tank, the product float will be resting on the weight at the bottom of the tank. In
an empty tank, the product level height reading may vary because of temperature changes even though there is no
liquid product in the tank. The probe does not measure the product level until the float becomes buoyant.
PROBE OUT OR NO PROBE DETECTED
1.
Check the probe part number to be sure the correct probe is installed.
2.
Be sure that each TLS RF box and the TLS Console have a good Earth Ground.
3.
Using the appropriate torx driver remove the cover of the suspect transmitter. Note that water should not be
present inside the transmitter enclosure.
4.
Check the 3-conductor wiring between the transmitter and the probe to ensure that each connection is se-
cured in the appropriate terminal (ref. Figure 16 on page 24). Verify that all wire connections are secure and
free of shorts.
5.
Check the input voltage from the battery going into the TLS XL-Transmitter, it should measure between 2.4
and 3.8 volts.
6.
Check that the two cable cord grips are tight.
7.
Replace the transmitter cover and the torque the securing screws to 10 inch-pounds.
8.
If necessary, refer to the TLS RF Wireless 2 System (W2) Installation and Maintenance Guide, part number
577013-964.
INCORRECT PRODUCT HEIGHT READING
Product Height Reading Error: 999.99
The product float magnet is in the null zone (ref. Table 1 on page 11) or the probe is malfunctioning.
Temperature Reading Error: -99.9
The working temperature range of the probe is -40°F t122°F.
A MAG-XL Flex Probe is designed to work with one float only, make sure the float is installed and moving freely on
the probe tube. If the product float is located in either the dead band (bottom) or the null zone (top) of the probe,
the product height on the TLS Console will be incorrect.
