Franklin Fueling Systems TSP-UHS - Manual

1
Overview
The TSP-UHS is a Standard sensor that is used to detect
the loss of a liquid in the normally solution-filled sensor
reservoir connected to the interstitial areas of double-wall
dispenser sumps. The sensor is supplied with electrical
connectors, 25 feet of cable, and a cord-grip fitting (see
diagrams). The TSP-UHS uses magnetic-float / reed-switch
technology (the sensor must be suspended vertically so
the float can freely follow the level of a liquid).
When the float drops more than 3/4 of an inch, the
magnetically sensitive reed switch will open. An open
circuit is recognized as an alarm-condition at the
intrinsically safe (I.S) leak detection circuits of the FFS
(Franklin Fueling Systems) ATG console.
Testing the TSP-UHS
This device can be tested by lifting the sensor from the
sensor reservoir. This will cause an alarm at the ATG
console. Test the sensor for proper operation on a yearly
basis, or more frequently per local code.
Materials Required
Optional: TSP-DB1 Epoxy Seal kit for no-strip electrical •
connectors – recommended for sites: within flood zones,
high groundwater tables, with poor drainage, or when
Junction Boxes are not used
1/2 or 3/4 inch NPT (National Pipe Thread, tapered), •
Rigid Metal Conduit (RMC) or nonmetallic (PVC) conduit
if allowed by local code
EYS Seal fittings and Epoxy to fill the fitting after •
operational testing is completed (as required).
Weatherproof Junction Box, gasket, and cover, plus •
a 3/4 to 1/2 inch NPT reducing bushing if 1/2 inch
RMC is used. Refer to the ATG Installation Guide for
recommended electrical Junction Boxes
Wire: THHN, TFFN or THWN, 18 AWG, White & Black, •
or Alpha Cable # 58411, 0.114 O.D., 1,500 feet (457
meters) max. length. If using nonmetallic (PVC) conduit,
Alpha Wire P/N 58411 (2.8 mm) 0.112” O.D. must be
used (INCON P / N 600-0062).
Slip joint pliers to seat the no-strip, self-sealing wire •
connectors. Connectors are supplied with the sensor
• UL Classified Thread Sealant or pipe dope.
