Introduction
The TTLSO single point strap-on temperature thermostat incorporates a
precision thermistor temperature sensor and provides a Form C relay output
(NO/NC) with an adjustable setpoint. The sensor is encapsulated to a 38 mm x 38
mm (1.5”x 1.5”) aluminum plate and adhered to a 38 mm x 25.4 mm (1.5 x 1“)
compressible foam. A 254 mm (10”) S/S Pipe clamp is provided to secure the
assembly to various sizes of pipe. All probes are constructed to provide excellent
heat transfer, fast response and are potted to resist moisture penetration.
Before Installation
Read these instructions carefully before installing and commissioning the
temperature thermostat. Failure to follow these instructions may result in
product damage. Do not use in an explosive or hazardous environment, with
combustible or flammable gases, as a safety or emergency stop device or in
any other application where failure of the product could result in personal
injury.
Take electrostatic discharge precautions during installation and do
not exceed the device ratings.

Mounting (Enclosure A)
The strap-on sensor installs directly onto any pipe where an immersion
sensor with thermowell can’t be installed.
Once a suitable spot is selected, remove a small block of insulation if
present. It is recommended that thermal compound be used to improve
heat transfer. Spread a liberal about on the pipe.
Open the worm gear clamp by swiveling the worm gear away from the
clamp and pull the clamp apart, as shown in Figure 1.
Place the sensor plate on the selected mounting area and wrap clamp
around the pipe. Re-insert clamp under the worm gear and pull until snug.
Lock in place by swiveling the worm gear towards the clamp. Tighten
worm gear clamp by using a standard screw driver or hex nut driver as
shown in Figure 2.
Using a Phillips screwdriver, remove the (2) screws, as shown in Figure 3.
Remove cover and set aside with screws for re-installing after wiring and
set up.
Two 21 mm (0.8125”) holes are provided for connection of either 12.77mm
(0.5” ) EMT or a cable gland style connector as shown in Figure 4. Insert the
EMT or cable gland connector through the hole and securely fasten using a
locknut. If only one connection hole is required, use the included hole cap
to cap off the unused one as shown in Figure 5.
Special care must be
taken not to damage any internal components during installation.
Make wire connections as per the “Wiring” illustrations on Page 2.
Once wiring and set up are complete, re-install cover and tighten the (2)
screws using a Phillips screwdriver.
