    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 cir- cuit for limited movement of hazardous machine components during installation, set up and positioning) In safety circuits in accordance with EN 60204-1 The unit is designed for use with...

  • Page 6: Safety Regulations

    Safety regulations Safety assessment Before using a device, a safety assessment in accordance with the Machinery Directive is required. The product as an individual component fulfils the functional safety requirements in accord- ance with EN ISO 13849 and EN 62061. However, this does not guarantee the functional safety of the overall plant/machine.

  • 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. The safety contact 17-18 is opened redundantly and the auxiliary contacts 25-26, 35-36 will close once the set pulse time has elapsed.

  • 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.
