2.2 General hazard warnings

The equipment must be installed by a professional familiar with the safety requirements and risks.

Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent

malfunctions and avoid personal injuries and property damage.

The operator of the system must ensure:

– Safety notices and operating instructions are available and observed,

– The respective national accident prevention regulations are observed,

– The permissible data and operational conditions are maintained,

– Safety guards are used and mandatory maintenance is performed,

– Legal regulations are observed during disposal,

– compliance with national installation regulations.

Maintenance, Repair

Please note during maintenance and repairs:

– Repairs to the unit must be performed by Bühler authorised personnel.

– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.

– Always use genuine spare parts.

– Do not install damaged or defective spare part. If necessary, visually inspect prior to installation to determine any obvious

damage to the spare parts.

Always observe the applicable safety and operating regulations in the respective country of use when performing any type of

maintenance.

3 Transport and storage

Only transport the product inside the original packaging or a suitable alternative.

The equipment must be protected from moisture and heat when not in use. It must be stored in a covered, dry, dust-free room

at room temperature.

4 Setup and Connection

DANGER Toxic, corrosive gasses

The sample gas can be harmful to the health if inhaled or on contact.

a) Ensure harmful gases are discharged safely.

b) Switch off the gas supply before performing maintenance and repairs, and flush the

gas lines with air. Secure the gas supply from accidentally being opened.

c) Protect yourself from toxic / corrosive gasses when performing maintenance. Wear

suitable protective equipment.

The temperature switch / sensor come complete and can be screwed onto the container with the thread. The maximum torque

of the screw-in thread is 25Nm.

When installing, be sure the sealing face is clean and even. Only screw the temperature switch / sensor into the fitted thread.

Sealed with an elastic sealing ring. No other sealants required.

5 Operation and control

DANGER Electric voltage

Risk of electric shock

a) Disconnect the unit from the mains when performing any maintenance.

b) Secure the equipment from accidental restarting.

c) The unit may only be maintained and opened by instructed, competent personnel.

The pin assignment for the respective models are listed in chapter Pin Assignment [> page13].

5.1 TF-M-Pt100/TF-E-Pt100/TF-M-Pt100-VAL Temperature Sensor

Type TF temperature sensors use a Pt100 temperature sensor per DIN/IEC751 class B to generate a temperature-dependent res-

istance signal. The Pt100 sensor is installed at the lowest point of the sensor tube to always ensure sufficient contact with the

medium being measured.

The temperature sensor TF-M-Pt100-VAL was designed for measuring storage temperatures and has a spring-loaded sensor

tube to allow installation free of play with a constant contact pressure at the measuring point.

5.2 TSM/TSK/TSA Bi-Metal Temperature Switch

The TS temperature sensors have a bi-metal temperature switch to signal a set temperature value. Unlike the TSM standard ver-

sion, the TSK and TSA versions with bi-metal switches have a lower hysteresis.

The TSA version is further specifically designed for installation in tube systems and cooling matrices.

The bi-metal switch is installed at the lowest point of the sensor tube to always ensure sufficient contact with the medium be-

ing measured.

5.3 Thermolog MK2/EK2 Temperature Sensor with 4-20mA Output

Type MK2 and EK2 temperature sensors use a Pt100 temperature sensor per DINEN/IEC60751 Class B to generate a temperat-

ure-dependent resistance signal.

The built-in electronics convert this resistance signal into a standard 4-20 mA two-lead signal.

The Pt100 sensor is installed at the lowest point of the sensor tube to always ensure sufficient contact with the medium being

measured.
