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 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 electronics of the pulse generator is designed as a metallic “d” enclosure which is intended for mounting directly on the corresponding gearbox. The counter disc is built-in into the enclosure, with a corresponding optical tracking, which is activated from the gearbox by a leading-in shaft. The connection cable mounted by the manufacturer is lead into the enclosure through a cemented stopping box, which is integrated in the enclosure.
Type variants covered: Encoder type name: 01-08
It can be delivered with a different number of channels (1-channel, 2-channels or 3-channels)
Supply voltage range 4.5 to 24 VDC, max 100 mA
Maximum measurable rotating speed: 600 rpm
Ambient temperature range
-30°C to + 70°C – with fixed mounted cable
-25°C to + 60°C – with movable cable
1. Permitted range of the ambient temperature: -30°C to +70°C with fixed mounted cable and -25°C to +60°C with movable cable. 2. The encoder cable must be routed and externally fixed in such a way that it is protected from mechanical damage. 3. The encoder is constructed with a permanently connected cable, which must be connected in a safe area or by use of a certified “e” or “d” junction box certified in accordance with IEC 60079-7 or IEC 60079-1. 4. The encoder shaft must be driven via a coupling arrangement that allows some radial and axial movement; otherwise damage to the shaft bearings may occur.
