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


The Optical Encoders EXAG are small flameproof enclosures containing electronics. The encoder housing is manufactured from stainless steel, acid proof stainless steel or aluminium with a drive shaft in one end shield. The shaft can be either solid type shaft (EXAG-A) or hollow type shaft (EXAG-H). The body makes one cylindrical joint with the drive end shield on another side. Each end shield (the drive end and the non-drive end) is secured to the body with six M4 counter bored socket head cap screws. O-rings are fitted to each cylindrical joint. There is a shaft seal on drive end seal, 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 up to four M20x1.5, M25x1.5, 1/2"NPT or 3/4"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 apparatus is rated at 300 mA maximum current and voltage range from 10 V dc to 30 V dc.

Rated speed for type variants with seal max 3000 rpm, without seal max. 6000 rpm.

Max. permissible load on the shaft: axial 60 N and 80 N radial.

Additionally the encoders meet IP64/65/66/67 in accordance with EN 60529.

 



 SPECIFIC CONDITIONS OF USE:   YES as shown below:
 
 

It is a condition of certification that the flame paths have to comply with the manufacturers drawings and can only be repaired by the manufacturer.

It is a condition of certification that the precautions must be taken to avoid dust from forming layers on the encoder.
 
The fasteners used to secure enclosure body to end shields shall have a minimum yield stress of 450 MPa.

Use only suitably certified Ex db IIC Gb and Ex tb III C Db cable glands, thread adapters and blanking elements.
