This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
The electrical apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The optoelectronic sensors, type OCT300- , operate as reflection light scanners. They react to variations in light intensity within a range of up to 300 mm.
The optoelectronic sensor, type OCS2000-M1K-N2, is a reflection-type light barrier. The light emitted is reflected by a reflector and collected by the receiver of the optoelectronic sensor. The sensor types mentioned above are designed for use in potentially explosive atmospheres.
The lowest permissible ambient temperature is –25 °C.
1. When using the optoelectronic sensors, types OCS2000-M1K-N2 and OCT300-M1K-N2, within the temperature range –25°C to –20 °C, the sensors shall be installed in an additional enclosure to protect them against impact effects.
2. The connectors of the optoelectronic sensors, types OCS2000-M1K-N2 and OCT300-M1K-N2, shall be installed in such a way that the degree of protection IP20 in accordance with IEC 60529 will be achieved as a minimum.
3. For the relationship between the type of the connected circuit, the maximum permissible ambient temperature and the temperature class as well as the effective internal reactance, reference is made to the table in the annex of this IECEx certificate.
