Safety Guidelines
Maintenance
The Pointek CLS100 requires no maintenance or cleaning.
Warning notices must be observed to ensure personal safety as
well as that of others, and to protect the product and the connected
equipment. Warning notices are accompanied by a clarification of
the level of caution to be observed.
This product can only function properly and safely if it is correctly
transported, stored, installed, set up, operated, and maintained.
WARNING - Parts of the enclosure are non-conducting and may
generate an ignition-capable level of electrostatic charge under
certain extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be subjected
to external conditions which might cause a build up of
electrostatic charge on non-conducting surfaces. Additionally,
cleaning of the equipment should be done only with a damp cloth.

Mounting
Location
Pointek CLS100 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
Note:
• 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 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, covering the probe.
Low Alarm
• When material reaches a minimum process level, uncovering the probe.
Power/Alarm Wiring
Non Intrinsically Safe Version
LOW Alarm
WARNING: The DC input terminal shall be supplied from a source
providing electrical isolation between the input and output, in
order to meet the applicable safety requirements of IEC 61010-1.
Note:
• For terminal block equivalents, see Enclosure Version on page 7.
• 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.
WARNING - Parts of the enclosure are non-conducting and may
generate an ignition-capable level of electrostatic charge under
certain extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be subjected
to external conditions which might cause a build up of
electrostatic charge on non-conducting surfaces. Additionally,
cleaning of the equipment should be done only with a damp cloth.
Solid state switch output
12-33 V DC (polarity determines operation)
