1.1 Intended ApplicationPull rope switches are installed in conveying systems foremergency cut-out of continuously running conveyors.The pull rope switches comply with the highrequirements of the trade associations, who obligatorilystipulate emergency devices in belt conveyors forpersonal security (UVV – VBG 10). Applications other than specified and unauthorized mod-ifications to the device or its components may lead to in-jury to persons and damage to the device for which themanufacturer is not liable."Intended Application" means that any work performedwith the device or on the device must be carried out inaccordance with these operating instructions. Onlyqualified personnel that are familiar with theregulations for the prevention of accidents as well asthe standard safety rules, are allowed to work on thedevice.This will ensure that you protect yourself and pre-vent damage to the device!

3.2 HEN and HEK with DUPLINE bus terminal

The pull rope switch types HEN and HEK with DUPLINEbus terminal differ from the basic types so far that a DU-PLINE field an installation bus node has been integratedin addition to the emergency cut-out function. The DU-PLINE bus enables the direct locating of a triggered pullrope switch within the total system of a conveying sys-tem.

Danger!The DUPLINE bus is a pure information busand not a safety bus! Switching off a convey-er system must still take place by discon-necting!

When the cut-out function is triggered the contacts of theswitch elements (13) S1 are opened to switch off theconveying system. When triggering the HEN resp. HEKwith DUPLINE bus a further switch element (13) S2 willbe closed. The integrated bus terminal recognises thisand transmits this information via the DUPLINE bus.Closing the switch element (13) S2 will also be indicatedby the light emitting diode (23).By means of the manual coder (type GAP 1605) an ad-dress will be applied to each pull rope switch via a pro-grammable plug (24).

5.2 Mounting

5.2.1 Important Mounting Pointers

By all means the pointers given below are to be consid-ered during the mounting to ensure correct operation ofthe emergency cord switches. In case of deviating con-ditions you have to consult KIEPE ELEKTRIK (see backcover for company address).� Only use KIEPE accessories for the mounting.� The operating temperature range of the emergency

cord switches and the activating arrangement is between – 25 °C and + 70 °C.

� Mounting has to be carried out at an ambient temper-ature of about + 15 °C.

� The emergency cord switch has to be mounted con-centrically between the fastening points. Deviation of up to maximum 3 % of the distance between the
