Page 4: About This Document
Non-Contact Safety Switch CES-A-C5H-EX 1. About this document 1.1. Scope These operating instructions are valid for all CES-A-C5H-EX. These operating instructions, the document “Safety information and maintenance” and any enclosed data sheet form the complete user information for your device. 1.2. Target group Design engineers and installation planners for safety devices on machines, as well as setup and servicing staff possessing special expertise in handling safety components. -
Page 5: Correct Use
Ì EN 60079-14 Ì EN 60079-31 The safety switch must be used only in conjunction with the designated CES actuators from EUCHNER. On the use of different actuators, EUCHNER provides no warranty for safe function. Important! Ì Devices with ATEX rating may be operated only with actuators that also have an ATEX rating for the same zone. -

Page 7: Explosion Protection Safety Concept
… Dc X = To prevent electrostatic charging, do not subject the switch to any processes that generates a large amount of charge. Safety switches with ATEX identification marking from EUCHNER are not safety devices as defined by the ATEX Directive. The specified type of protection ic applies only to the integrated reader module. The electrical circuits in the device connec- tion (M12 plug connector) are not intrinsically safe! If mounted on heat/cooling sources, the permissible ambient temperature (see technical data) must be observed. -
Page 8: General Safety Precautions
Prior to use, read the operating instructions and keep these in a safe place. Ensure the operating instructions are always available during mounting, setup and servicing. EUCHNER cannot provide any warranty in relation to the readability of the CD for the storage period required. For this reason you should archive a printed copy of the operating instructions. -
Page 9: Function
Operating Instructions Non-Contact Safety Switch CES-A-C5H-EX 7. Function The safety switch monitors the position of movable guards. The safety outputs are switched on/off when the actuator is moved to/removed from the operating distance. The system consists of the following components: coded actuator (transponder) and switch. -

Page 12: Mounting
Operating Instructions Non-Contact Safety Switch CES-A-C5H-EX 9. Mounting WARNING On use in potentially explosive atmospheres the following applies: Ì Protection against mechanical effects on the switch: - Install switch so that the rear of the housing is entirely covered in order to protect it from me- chanical damage through impact. -
Page 13: Operating Instructions
Operating Instructions Non-Contact Safety Switch CES-A-C5H-EX Note the following points: Ì Actuator and safety switch must be easily accessible for inspection and replacement. Ì Actuator and safety switch must be fitted so that - the front faces are at the minimum switch-on distance 0.8 x S or closer when the guard is closed. -
