Auto-Reset Safety Module Datasheet

Cover image of technical document

Overview

The Auto-Reset Safety Module (CE-SA-019-0001) is designed for situations where the machine needs to automatically reset from an emergency stop (e-stop) event without requiring the user to press a physical reset button. This module enables the machine to resume normal operation when the user exits the danger zone in the correct manner and orientation, resetting the safety system automatically. It interfaces with up to three safety devices on MachineMotion V2 and can connect to area scanners, light curtains, and other safety devices to perform safety functions. The module will automatically reset its state if the correct zone exit sequence is followed. Every safety equipment deployment should be paired with a safety assessment to ensure risk reduction.

Important Notes

Safety


Vention’s safety modules perform safety functions as a part of a whole installation or machine. A complete safety system normally includes sensors or input units, logic units and contactors or output units. The manufacturer of the installation or machine is responsible for ensuring proper functioning of the whole system. The total concept of the control system into which the safety module is integrated must be validated by the user. Vention cannot guarantee all specifications of an installation or a machine without being responsible for the risk assessment and the design of the safety system. Vention takes over no liability for recommendations which are given or implied in the following description.
The following items must be taken into consideration during the design, risk assessment & installation of the safety system :

  • The Safety Modules shall be put into operation only after the safety functions have been tested during the commissioning.

  • According to EN IEC 60204-1:2018 and EN ISO 10218-1:2011 it is not allowed to restart automatically after emergency stop. Therefore the control systems of the connected devices have to disable the automatic start after emergency stop.

  • Opening the Safety Module or implementing unauthorized changes voids any warranty.


Functional error! Danger to life, risk of serious injuries or property damage

  • The Auto-Reset Safety Module may only be connected to the equipment listed in this manual.

  • The Auto-Reset Safety Module does not monitor the input redundant signals at the safety device ports. If the connected devices do not have monitoring of its output signals, the performance level of the safety function can be reduced.

  • When using the auto-reset function in a full body entry application, we recommend to use Devices 1, 2 & 3. If the risk assessment doesn’t show risks of using only two zones, only Device 1 and Device 2 can be used;

  • When using the auto-reset function in a partial body entry application, it is possible to use only the Device 1 port and connect a jumper to Device 2 and Device 3.

  • When using the auto-reset function the risk of having two personnes entering the safeguard space at the same time shall be considered in the risk assessment. For example, that one of the personne access a non-monitored dangerous area from the monitored area.

  • The auto-reset module should only be used in a safety chain connected to the Reduced port of a Smart Robot Safety Module and/or if the safety assessment permits it.

    • The risk assessment shall demonstrate that when triggering the safety devices connected to the Device ports, the state of the machine and the safety distance are acceptable;

  • The Auto-Reset Safety Module is designed to operate in indoor environments without dust or high humidity. Dust and dampness may lead to malfunction. Do not install or operate the Muting Safety Module outdoors.

  • The machine shall be designed in such a way that it is not possible to press the reset button from inside a safeguarded area without triggering one of the devices connected to the Device ports.

*Note: Due to the inrush of safety devices, the E-FUSE might trip if you power the unit while 4 or more Safety devices are plugged into it. To fix this issue, you can remove power from the MachineMotion and start it again.

** Note: In North America the Safety Module shall be supplied by a certified class 2 power supply. In Europe, the Safety Module must be supplied by an SELV circuit. When powered by the MachineMotion those requirements are met.

Functionality

The Auto-Reset Safety Module has 3 devices as inputs. The devices can be multiple light curtains or a single area scanner with 3 outputs. The transitions must overlap and an incorrect sequence will cancel the internal reset. The internal reset does not send a reset outside of the module.

Figure 2: Auto-Reset Safety Module logic

Figure 2: Auto-Reset Safety Module logic

Once the sequence is initiated, the safety out port is triggered. If the sequence is not respected the module will not auto-reset. The internal reset happens 5 seconds after the sequence is respected. The auto-reset module can change the state of the safety out if certain conditions are met. If device 1 is triggered then not triggered, the safety out will be tripped when the device 1 is triggered then when the device 1 is not triggered after a delay the safety out will be reset. The Auto-reset module does not send a reset pulse (this would be unwanted since it could potentially automatically reset the emergency stop safety chain).

Safety Data

The Vention’s Safety Modules realize the following safety functions :

  • System emergency stop output at the Safety OUT connector from the Safety IN port (E-stop_SafetyIN-to-SafetyOUT);

  • The Device port (light-curtain or area scanner) to the Safety OUT portSystem emergency stop output at the Safety OUT connector from a Safety Device port (E-stop_Device-to-SafetyOUT); and

  • System reset propagation from the Safety IN port to the Safety OUT port (Reset_SafetyOUT).

For each of these functions, safety data can be found in the following table.
