Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 

The Optical Encoder EXME is a small flameproof construction enclosure containing the electronics. The encoder housing is manufactured from stainless steel or acid proof stainless steel with drive shaft in one enclosure end shield. The shaft can be either solid type shaft (EXME-A) or hollow type shaft (EXME-H). The drive end shield is secured to the body with six M4 counter bored socket head cap screws. The non-drive end shield is secured to the body with six M4 counter bored socket head cap screws. The body makes one cylindrical joint with the non-drive shield on one side and another cylindrical joint with the drive end shield on another side. O-rings are fitted to each cylindrical joint. There is a shaft seal on drive end shield, where two ball bearings are mounted to the cylindrical joint between the shaft and the drive end shield.

The encoder housing can be provided with one to four M20 × 1.5 – 6H, or M25 × 1.5 – 6H, or ½’’ NPT, or ¾’’ NPT threaded entries on the non drive end shield. These threaded entries are closed with the suitable separately IECEx certified cable glands. All unused entries must be closed with suitable separately IECEx certified blanking elements. The fasteners used to secure enclosure body to end shields shall have a minimum yield stress of 450 MPa. The apparatus is rated at 300 mA maximum current and voltage range from 4.5 V d.c or 10 V d.c. to 30 V d.c.. The encoder model numbers and coding is shown in the drawing 00240171. Rated speed for type variants with shaft seal maximum 3000 rpm; without shaft seal maximum 6000 rpm.



 SPECIFIC CONDITIONS OF USE:   YES as shown below:
 
 
  1. As flameproof joints parameters are different from the minimum/maximum defined in Table 2 of IEC 60079-1, the repair must be carried out only by the manufacturer in accordance with the certification drawings.
  2. The manufacturer’s instruction must be followed to minimize the risk from electrostatic discharge.
  3. For ambient temperature 65°C to 70°C, cable must be rated for at least 85°C.
  4. The fastener used to secure enclosure body to end shields shall have a minimum yield stress of 450Mpa
  5. Use only suitably certified Ex db I Mb cable glands, thread adaptors and blanking elements comply to ambient temperature range - 40°C to + 70°C and relevant IP rating -IP64/65/66/67/68 (1h/1 meter)
