1.3.3 Enabling device and hold-to-run functionalityThree-position enabling deviceThe three-position enabling device is a manually operated, constant pressurepush-button which, when continuously activated in one position only, allowspotentially hazardous functions but does not initiate them. In any other position,hazardous functions are stopped safely.The three-position enabling device is of a specific type where you must press thepush-button only half-way to activate it. In the fully in and fully out positions,operating the robot is impossible.NoteThe three-position enabling device is a push-button located on the teach pendantwhich, when pressed halfway in, switches the system to MOTORS ON. Whenthe enabling device is released or pushed all the way in, the manipulator switchesto the MOTORS OFF state.To ensure safe use of the teach pendant, the following must be implemented:• The enabling device must never be rendered inoperational in any way.• During programming and testing, the enabling device must be released assoon as there is no need for the robot to move.• Anyone entering the working space of the robot must always hold the teachpendant. This is to prevent anyone else from taking control of the robotwithout his/her knowledge.Hold-to-run functionThe hold-to-run function allows movement when a button connected to the functionis actuated manually and immediately stops any movement when released. Thehold-to-run function can only be used in manual mode.How to operate the hold-to-run function for IRC5 is described in Operatingmanual - IRC5 with FlexPendant.24 Product manual - DressPack/SpotPack IRB 6650S3HAC055424-001 Revision: C© Copyright 2004-2018 ABB.
