Safety notes
▸
Only use original SICK spare parts.
For devices used in potentially explosive atmospheres:
▸
Maintenance and inspection should only be carried out by experienced/trained
personnel with knowledge of the rules and regulations for potentially explosive
atmospheres, especially:
– Ignition protection types
– Installation regulations
– Zone classification
▸
Standards to be applied:
– IEC 60079-14, Annex F: Knowledge, skills and competencies of responsible
persons, operatives and designers.
– IEC 60079-17: Electrical installations inspection and maintenance
– IEC 60079-19: Equipment repair, overhaul and reclamation
WARNING:
Risk of burns through hot gases
▸
With process temperatures > 65°C, let the TRANSIC151LP cool down before starting
maintenance work.
WARNING:
Toxic gases escaping
▸
Ensure the seals are fitted.
▸
Incorrect sealing materials lead to leaks.
▸
Check the installation regularly for leaks.
WARNING:
Risk of fire through reaction with oxygen
▸
Keep components with sample gas contact free from grease and dust.
WARNING:
Risk of injury through pressure
▸
Only assembly and disassemble the TRANSIC151LP when free from pressure.
When necessary, provide separating elements to ensure safe installation and removal.
WARNING:
Risk of explosion through use of an unsuitable flange
Oxygen measurement only functions in the range 0.8 to 1.4 bar(a).
Do not use the flange with M5 screws when the pressure to be expected is above
1.5 bar absolute or the plant is designed for such pressures.
▸
Only use components designed for the process pressure in the application.
▸
Observe the components pressure conditions,
see “Pressure suitability”, page 78
▸
Observe regional regulations
CAUTION:
Laser beam invisible
▸
Switch the TRANSIC151LP off during cleaning
Cleaning tools positioned on the probe can reflect the laser beam coming out of the
probe.
