Series TSX3 Digital Refrigeration Temperature Switch
The Series TSX3 Digital Temperature Switch was designed to control the
compressor, fan, and defrost in refrigeration applications. This generation of
controls has field selectable engineering units and input temperature types in order
to reduce the combination of parts that need to be stocked. A built in real time clock
is used for HACCP logging of temperature alarms caused by temperatures out of
their set limits or loss of power. The Intelligent Defrost parameters manage the
defrost cycle in order to save energy cost. The digital input can be used to remotely
trigger a defrost cycle, monitor cooler door status, or act as an external alarm. For
programming multiple units, the model TS2-K configuration key can be used to
quickly download parameter settings.
INSTALLATION
NOTE: Unit must be mounted away from vibration, impacts, water and corrosive
gases.
• Cut hold in panel 71 x 29 mm (2.80 x 1.14 in).
• Use the supplied gasket or apply silicone around the perimeter of the hole to
prevent leakage.
• Insert unit into hole from the front side of the panel.
• Slide the mounting bracket securely against the panel from the rear of the unit.
• Wiring diagram is displayed on the top of the control.
Wiring
Avoid installing the temperature probe cables and the digital input wires in close
proximity of any power cables. If the length of the probe cables is longer than 100
meters, a recalibration adjustment may be made using the P1 parameter.
