Correct Use - EUCHNER CES-A-UEA-02B Operating Instructions Manual

2. Correct use

Evaluation units of the series CES-A are used to evaluate safety-related signals from EUCHNER read heads. The system
forms an interlocking device. It meets the requirements according to EN IEC 60947-5-3.
The system consists of evaluation unit, read head and actuator. It forms an interlocking device with low coding level (type 4).
In combination with a movable guard and the machine control, this system prevents dangerous machine functions from oc-
curring while the guard is open. A stop command is triggered if the guard is opened during the dangerous machine function.
This means:
Ì Starting commands that cause a dangerous machine function must become active only when the guard is closed.
Ì Opening the guard triggers a stop command.
Ì Closing a guard must not cause automatic starting of a dangerous machine function. A separate start command must
be issued. For exceptions, refer to EN 12100 or relevant C-standards.
Before use, a risk assessment must be performed on the machine, e.g. according to the following standards:
Ì EN ISO 13849-1
Ì EN ISO 12100
Ì IEC 62061
Correct use includes observing the relevant requirements for installation and operation, e.g. according to the following
standards:
Ì EN ISO 13849-1
Ì EN ISO 14119
Ì EN 60204-1
The following components can be connected to the evaluation unit CES-A-UEA...:
Ì CES read heads
Ì CEM read heads
Ì CET read heads
For further information, refer to the operating instructions of the corresponding component and to Table 1: Possible com‑
binations for CES components on page 6.
Important!
Ì The user is responsible for the proper integration of the device into a safe overall system. For this
purpose, the overall system must be validated, e.g. in accordance with EN ISO 13849-2.
Ì Correct use requires observing the permissible operating parameters (see technical data).
Ì If a data sheet is included with the product, the information on the data sheet applies.
Ì It is only allowed to use components that are permissible in accordance with the table below.
