Initial Start-up and Maintenance:
Initial Start-up: Before initial operation, remove all foreign objects and dust from pressure switch enclosures. Verify correct functioning to avoid dangerous malfunctions.
Inspection and Maintenance: Compliance with EN 60079-17 standards is required for inspection and maintenance of electrical installations in hazardous areas. Only original spare parts should be used.
Qualifications: Maintenance should be performed by trained personnel familiar with explosion protection and installation procedures.
Maintenance Intervals: These should be determined based on application-specific conditions.
Operating Temperature: The permissible operating temperature range is -25°C to +70°C, considering additional heat sources.
Enclosure and Disposal Requirements:
Enclosure Requirements: Check the condition of gaskets and seals to ensure proper sealing.
Dust Ingress: Clean enclosures if dust enters during maintenance.
Defective Pressure Switches: Report or return defective units to the manufacturer.
Disposal: Disposal must comply with national directives like RoHS and REACH.
Technical Specifications:
Pressure Ranges: Detailed pressure ranges and specifications for different types of pressure switches are provided, with references to complete technical specifications available on the manufacturer's website.
