Page 4: About This Document
Scope This document is valid for: Ì Safety Relay with IO-Link for emergency stop, safety door and light grid monitoring ESM-CB 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
Operating Instructions Safety Relay with IO-Link ESM-CB 2. Correct use The safety relay is used to monitor safety-related signaling devices and to control actuators. The safety circuit monitors two sensor circuits. Each sensor circuit can have one or two channels. When at least one sensor circuit is interrupted, the safety relay initiates the safe state. -
Page 6: Description Of The Safety Function
Operating Instructions Safety Relay with IO-Link ESM-CB 3. Description of the safety function 3.1. Monitoring of sensor circuits The safety circuit monitors two sensor circuits. Each sensor circuit can have one or two channels. The safety relay can be operated only if both sensor circuits are used. If only one sensor circuit is used, the second sensor circuit must be bridged. -
Page 7: Exclusion Of Liability And Warranty
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 8: Function
Operating Instructions Safety Relay with IO-Link ESM-CB 6. Function 6.1. IO-Link communication and functions The safety relay is an IO-Link device. Communication via IO-Link offers cyclical (process data) and acyclical (device data and events) data exchange. Important! The cyclical and acyclical data can be found in chapter 14. IO-Link communication and diagnostic data. -
