INFORMATION This gives advice on applications and provides information on special fea- tures. Safety Intended use The unit operates as a pulse relay in accordance with EN ISO 12100:2010 section 6.2.11.10, 6.3.2.4 and 3.28.9 (inching circuit for limited movement of hazardous machine components during installation, set up and positioning) in safety circuits in accordance with VDE 0113-1 and IEC 60204-1 The unit is designed for use with... -
Page 6: Safety Regulations
Safety regulations Safety assessment Before using a device it is necessary to perform a safety assessment in accordance with the Machinery Directive. Functional safety is guaranteed for the product as a single component. However, this does not guarantee the functional safety of the overall plant/machine. In order to achieve the re- quired safety level for the overall plant/machine, define the safety requirements for the plant/machine and then define how these must be implemented from a technical and organ- isational standpoint. -
Page 7: For Your Safety
For your safety The unit meets all the necessary conditions for safe operation. However, please note the following: Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120 VDC) are present on the unit, connected control elements and sensors must have a rated insulation voltage of at least 250 V. -

Page 9: Function Description
Function description The unit is ready for operation when the feedback loop Y1-Y2 is closed. Input circuit closed (supply voltage is present) "POWER" LED is illuminated. The safety contact 17-18 will be closed immediately and the auxiliary contacts 25-26, 35-36 will open, time sequence starts. The "OUT" LED is lit. -
Page 10: Installation
Installation The unit should be installed in a control cabinet with a protection type of at least IP54. Use the notch on the rear of the unit to attach it to a DIN rail (35 mm). When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket or end angle). -

Page 12: Operation
Operation When the relay outputs are switched on, the mechanical contact on the relay cannot be tested automatically. Depending on the operational environment, measures to detect the non-opening of switching elements may be required under some circumstances. When the product is used in accordance with the European Machinery Directive, a check must be carried out to ensure that the safety contacts on the relay outputs open correctly. -
