Installation
Handling Precautions
1. At process connection.
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.
• This housing may only be opened for maintenance, local operation, or electrical
installation.
• Before installing the instrument, verify that the environment complies with any restrictions
specified on the device nameplate.
WARNING: To prevent damage, all CLS200 Standard units with a rod longer than
2 m (6.5 ft) must be handled as described below.
When lifting CLS200 from a horizontal position, support it at these three points:
At the end of the rod
before the sensor Midway along the rod At the process connection or flange
Once vertical, CLS200 may
be held by the process
connection or flange:
Note: Unit shown is CLS200 Standard
Extended Rod Version. Handling
precautions apply to all CLS200
Standard units with rods longer than
2 m (6.5 ft).

Mounting Location
• Do: provide a sun shield to protect the transmitter from direct heat radiation.
• Do not: exceed the permissible ambient temperature limits
• Do not: mount Pointek CLS200/300 in locations subject to strong vibrations (if it can be
avoided).
Standard probe length: top or side mounting
High level alarm
• normally mounted into the vessel top, or
• through the tank wall at the detection level
Low level alarm
• mounted through the tank wall at the detection level
Standard configuration with extensions: top mounting
• Designed for top mounting, for high or low level alarm. Suspend the probe vertically so
that it reaches into the process at the desired detection level.
Process Cautions
• The maximum allowable torque on a horizontally installed rod is 15 Nm.
• Keep unit out of path of falling material, or protect probe from falling material.
• Avoid areas where material build up occurs.
• Take into account material surface configuration when installing unit.
• Ensure tensile load does not exceed probe or vessel ratings
Mounting Instructions
Pointek CLS200/300 is available in three thread types: NPT, or BSPT (R), and BSPP (G)1. Make
sure the mounting connection threads are of the same type, then simply screw the device into
the process connection, and hand tighten.
Notes:
• Keep the sensor at least 50 mm (2") away from any nozzle or tank wall.
• If multiple units are used, allow at least 100 mm (4") between them, to prevent interference
(mount diagonally if space is restricted).
1. A sanitary connection is also available.

Wiring
1. Loosen the lid clip and remove the lid to access the connectors and electronics. (The
diagram on the next page can also be found on the underside of the lid, together with a
guide to switch function).
2. Connect the wires to the terminals (polarity is not important).
3. Ground the instrument according to local regulations.
4. Tighten the gland to form a good seal.
5. After adjusting the settings, replace the lid and secure the lid clip.
WARNING: All field wiring must have insulation suitable for at least
250 V.
Notes:
• Only qualified personnel are authorized to install and operate this equipment in
accordance with established safety practices and standards.
• The Protective Earth Terminal indicated by must be connected to reliable ground.
• All wiring must be done by qualified personnel in accordance with all governing
regulations.
• The equipment must be protected by a 15A fuse or circuit breaker in the building
installation.
• A circuit breaker or switch in the building installation, marked as a disconnect switch,
shall be in close proximity to the equipment and within easy reach of the operator.
• Use shielded cable, wire gauge 20 AWG to 14 AWG (0.5 mm2to 2.0 mm2). Use a cable
with a braided metallic shield for CE installations (or armoured cable where applicable).
• Maximum working voltage between adjacent relay contacts is 250 V.
• Relay contact terminals are for use with equipment which has no accessible live parts
and wiring which has insulation suitable for at least 250 V.

Operation: CLS200
The alarm delay and trip point settings can be adjusted, using indicators L1, L2 and L3 to help
set potentiometers P1 and P2.

Alarm Output
The Failsafe function controls the response of Pointek CLS200 to a fault, so that it puts the
process into a safe mode of operation. (For more details, please refer to the full manual.)
