Auto-Reset Safety Module AI Datasheet

Overview

The Auto-Reset Safety Module AI (CE-SA-019-0001__2) is designed for situations where a collaborative robot needs to automatically reset from collaborative mode without requiring the operator 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 collaborative safety function automatically. It interfaces with up to three safety devices and can connect to area scanners, light curtains, and other safety devices to perform safety functions. Every safety equipment deployment should be paired with a safety assessment to ensure risk reduction.

This document covers requirements for latest version of Vention’s Auto-Reset Safety Module. For previous version, refer to link below:

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 AI may only be used in VENTION safety ecosystem;

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

• No emergency stop button shall be connected to the Safety IN port;

• 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 Robot Safety Module AI 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. Refer to ISO 13855 and ISO 13857 for additional considerations on safety distances;

• The Auto-Reset Safety Module AI 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.

General Specifications

Electrical Specifications

** 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 AI those requirements are met.

LED Indicators

Functionality

The Auto-Reset Safety Module AI has 3 inputs ports (Zone 1, Zone 2 and Zone 3) and can connect with up to 3 devices. These devices can be multiple light curtains or a single area scanner with 3 outputs. The inputs must be triggered sequentially and there must be an overlap where 2 contiguous zones are triggered at the same time. Any incorrect sequence will disable the automatic reset and require a user reset. The Auto-Reset Safety Module AI should always be connected to the Reduced Speed port of a Robot Safety Module AI. Only the collaborative mode function is affected by the automatic reset.

Once the sequence is initiated, a fault is immediately triggered and latched on the Safety Out port. 5 seconds after the sequence is completed, the module will reset the fault on the Safety Out port. If the sequence is not respected, the module will latch the fault indefinitely, until a user presses on a reset button. The full sequence does not have to be completed for the automatic reset to occur. For example, an automatic reset would occur if a user only triggers Zone 1 then exits the cell without ever triggering Zone 2. The Auto-Reset Module AI does not have agency over the physical Reset signal on pin 7 of the Safety In and Safety Out port and thus cannot reset an emergency stop.

Port definitions and pinouts

Safety Out - M12, male, 12-pin, A-Keyed

The Safety Out port connects to the Reduced Speed port of the Robot Safety Module AI, or to another Safety Module when daisychaining.

Safety In - M12, female, 12-pin, A-Keyed

The Safety In port connects to the Safety Out port of another Safety Module when daisychaining. If the port is unused, plug the included yellow jumper (CE-SA-102-0001).

Zone 1/2/3 - M12, female, 12-pin, A-Keyed

The Zone 1/2/3 ports connect to safety devices. If any of these ports is unused, plug the included black jumper (CE-SA-125-0001).

Mounting

Install the module mounting bracket (CE-HW-005-1002) to the extrusion with the screws provided (HW-FN-003-0018). Install the module onto the mounting bracket as illustrated below.

Wiring Diagram

*Note: Insert a jumper on any unused safety input for proper functionality. See table below to identify the appropriate jumper part number (included with the module).

Important information

• The electronic fuse contained in the Auto-Reset Module AI protects from internal faults and external faults, but only on the Zone ports. The 24V power output on the Safety In port is not protected by the electronic fuse. The electronic fuse has an auto-retry mechanism (it does not latch faults and does not require a power cycle to reset).

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.

The above information have been calculated based on the following operation conditions:
