Flexibly safe. Transponder-coded safety systems CES
Open the catalog to page 1Transponder-coded safety systems CES The coded electronic safety systems CES are modern interlocking devices of type 4 for the protection of persons, machines and processes. They are based on non-contact transponder technology and consist of a coded actuator, a read head and evaluation electronics. In some systems, the read head and evaluation electronics form a self-contained unit. A unit of this kind is referred to as a safety switch. All safety functions are combined in a single component here (internal evaluation). With external evaluation, the actuator is read via a separate read head...
Open the catalog to page 2External evaluation With external evaluation, the evaluation electronics for the transponder signals are accommodated in a separate housing. This separation minimizes the read head’s size. This is particularly advantageous if the available space at the location to be protected is very limited. Evaluation of signals in the control cabinet Transponder signals are evaluated in the evaluation unit CES, directly in the control cabinet. Up to four read heads (which may be of different types) can be connected and evaluated. The wiring work is minimal, because each read head can be connected to the...
Open the catalog to page 3Evaluation of signals in the field The transponder signals are evaluated in the field evaluation unit CES-FD. Read heads CKS and CES-LMN can be connected to the device via an M8 plug. The status of the CES-FD can be seen at any time on two LED indicators. The switched semiconductor signals (safety outputs) are forwarded to the higher-level control system via an M12 plug connector. CES-AZ CES-AZ Internal evaluation With internal evaluation, the evaluation electronics and read head are accommodated in the same housing (safety switch). Transponder signals are evaluated in the field, not in the...
Open the catalog to page 4n System family AR/BR For series connection of up to 20 safety switches CES. All EUCHNER products with an AR or BR interface can be connected in series. A mix of AR and BR devices must not be used in a switch chain, however. Three different wiring concepts are available: 1. Series connection in the control cabinet Wiring takes place in the control cabinet. All information about the status of individual CES products can be forwarded directly to the control system. 2. Series connection via plug connectors in the field All safety switches used are interconnected by Y-plugs in the field, and...

Open the catalog to page 6n Protection against tampering with unicode evaluation Each CES actuator features a transponder with high coding level (corresponding to EN ISO 14119), enabling absolute protection against tampering. The highly coded actuator is precisely assigned to the safety switch via a teach-in operation. This prevents bypassing the guard using an actuator of identical design. There are different types of actuator recognition: Unicode: Only the actuator taught-in for the safety switch is recognized. F ixcode: An actuator is permanently assigned to the safety switch on delivery and cannot be replaced...
