6. Power up Console for next step.
7. Test sensor (verify that an alarm is produced at ATG

console), if it does produce an alarm, seal EYS seal

fittings and electrical connectors with epoxy.

8. Turn off power again if other devices are to be

installed (Repeat Step 3).

9. Reinstall all safety covers and guards, junction

box gasket and covers – use pipe-dope to seal all

fitting threads.

10. Install the manhole cover.
11. Record the location where the sensor was

installed on the chart on the last page of these

instructions. This information will be needed when

programming the ATG.

12. Turn on power and program the ATG – Ref: all

relating to Sensors in the Setup / Programming

Guide manual.

General Installation Notes

* Steel double-walled tanks are equipped with a pipe

that allows direct access to the bottom of the interstitial

(annular) space. When installing a riser pipe in a steel

tank, codes may require a non-conductive isolation

bushing be installed between the tank and riser pipe.

It is the installer’s responsibility to

comply with all applicable federal, state

and local codes. Failure to do so may

create an Environmental Hazard.

* Fill the bottom of the manhole with crushed stone to

facilitate drainage when the TSP-ULS is installed in the

interstitial space of a steel tank. Do not cover the top of the

riser with fill material, it must remain accessible for service

and for sensor installation.
Plan your conduit routing. Dig trenches as necessary to

install rigid threaded conduit (RMC) from each manhole

junction box to the Intrinsically Safe (I.S.) knockouts at the

ATG console. The conduit may enter the manhole either

from its bottom or through its side. A junction box inside

of the building as a pull box to combine several sensor

cables. If this is done, then only one I.S. conduit knockout

will be used.

Conduits must have EYS seal fittings

installed in accordance with NFPA

70 (National Electric Code) and NFPA

30A (Automotive and Marine Service

Station Code). Failure to seal conduits

in accordance with NFPA 30A, and

NFPA 70 could allow flammable vapors

to travel through the conduit in the

ATG console. An explosion could

result causing serious injury, property

loss, or death.

You must install a weatherproof, electrical junction

box inside each manhole. The junction box should be

installed high on the manhole wall to prevent it from being

submerged during heavy rains.

Seal all threaded fittings and conduit

threads to produce a weatherproof seal

during installation/maintenance.

Figure 4: TSP-ULS Wiring

Reference the ATG Installation Manual and see Figure 4

(above) for TSP-ULS sensor wiring details. The two-wire

TSP-ULS sensor does not have a red (power) conductor,

therefore, the PWR (RED) interface terminal at the console

is not used. When a 3-conductor Alpha cable is used, the

red conductor can be clipped or taped back on both ends.

Testing the TSP-ULS

Testing this device is a matter of rotating the sensor 180

degrees with the bottom up, to cause an alarm at the ATG

console. Test the sensor for proper operation on a yearly

basis, or more frequently per local code.
