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.
