Pointek CLS 100 Quick Start Manual
Pointek CLS 100 is a compact 2-wire capacitance switch for level detection in constricted
spaces, interfaces, solids, liquids, slurries, and foam. The PPS (polyphenylene sulfide)
probe (optional PVDF [polyvinylidene fluoride]) is chemically resistant with an effective
process operating temperature range from -40 to 100 °C (-40 to 212 °F).
The Pointek CLS 100 versions:
•Integrated cable version with stainless steel process connection and probe options
of PPS or PVDF.
•All-plastic version has a thermoplastic polyester enclosure with a PPS process
connection combined with a PPS probe.
•Standard enclosure version with a thermoplastic polyester enclosure with a
stainless steel process connection in combination with a PPS or PVDF probe.
The Pointek CLS 100 approval types:
•General Purpose/Dust Ignition-Proof version (all-plastic and enclosure), providing
4/20 or 20/4 mA toggle output, and a relay output or solid state output.
•Intrinsically Safe version (enclosure or integrated cable), providing 4/20 or 20/4 mA
toggle output and solid state switch output for detection of high and low process
material levels.

Mounting
Location
The Pointek CLS 100 is normally mounted into the vessel top (high detection alarm) or
through the tank wall at the detection level (high or low detection alarm).
Installation Features and Restrictions
Notes
• Installation shall only be performed by qualified personnel and in accordance with local
governing regulations.
• This product is susceptible to electrostatic shock. Follow proper grounding procedures.
• When using multiple units, sensors must be 100 mm apart. Mount diagonally if vertical
space is restricted.
Vertical Angle Horizontal
Note: Mounting diagrams apply to all plastic all versions.
Standpipes Wall Restriction
Process Cautions
• Keep out of path of falling material.
• Consider material surface configuration when installing unit.
• Protect probe from falling material.
• Avoid areas where material buildup occurs.

Definitions
The alarm conditions below can be detected in a fail-safe or non fail-safe mode.
Fail Safe
• The sensor connection arrangement is fail-safe if the output status is in high
alarm status when power fails; open contact state prevents material overflow.
• The sensor connection arrangement switches to the fail-safe low alarm status
when power fails; this open contact state prevents material running dry.
High Alarm
• When material reaches a maximum process level, uncovering the probe.
Low Alarm
• When material reaches a minimum process level, uncovering the probe.

Notes:
• For terminal block equivalents, see Enclosure Version on page 6.
• The solid-state output should only be used in circuits where the current is limited by a
proper load.
• Due to the limited switching capabilities of the solid-state switch component, an
auxiliary relay must be applied when switching high-current/high-voltage apparatus.

Protection Diodes
Always use a protection diode when driving an external relay with the solid state switch
or relay contact. This prevents possible switch damage due to inductive spikes generated
by the relay coil.
Orient the diode based on the current flow.
