About this manual
This manual is valid for all field evaluation units CES-FD-AP-M-01-… (Multicode) and
CES-FD-AP-U-01-… (Unicode).
Correct use
The field evaluation units series CES are safety devices for monitoring movable
safety guards.
The complete safety system consists of three components:
coded actuator (transponder), read head and field evaluation unit.
- In combination with a separating safety guard and the machine control, this safety
system prevents dangerous machine movements from occurring while the safety
guard is open. A stop command is triggered if the safety guard is opened during
the dangerous machine function.
Before safety components are used, a risk assessment must be performed on the
machine, e. g., in accordance with:
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì EN ISO 12100, Safety of machinery – General principles for design – Risk as-
sessment and risk reduction
Ì IEC 62061, Safety of machinery. Functional safety of safety-related electrical,
electronic and programmable electronic control systems.
Correct use includes compliance with the relevant requirements for installation
and operation, for example
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì EN 1088, Safety of machinery. Interlocking devices associated with guards.
Principles for design and selection
Ì EN 60204-1, Safety of machinery. Electrical equipment of machines. General
requirements
Ì EN 60947-5-3, Specification for low-voltage switchgear and controlgear. Con-
trol circuit devices and switching elements. Requirements for proximity devices
with defined behavior under fault conditions
The unit must be used only in conjunction with the CES read heads and CES ac-
tuators from EUCHNER. On the use of different actuators, EUCHNER provides no
warranty for safe function.
