Muting Safety Module AI Datasheet

Overview

The Muting Safety Module AI (CE-SA-015-0001__2) is essential when an emergency stop (e-stop) function is required in the machine, ensuring a critical layer of safety. This module interfaces with up to four safety devices and is the default safety module for safety systems with MachineMotion AI. It can connect to area scanners, light curtains, and other safety devices to perform safety functions, which are essential for reducing risk. Additionally, it can be used to mute light curtains or area scanners, allowing the passage of objects like boxes on a conveyor without triggering an e-stop. 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 Muting 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 Muting Safety Module AI may only be used in VENTION safety ecosystem;

• The Muting Safety Module AI 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.

• The Muting function is not considered to be a safety function.

• Muting must only be performed on Material. A risk assessment shall be performed to verify that the use of the muting function does not create new hazards. Refer to IEC/TS 62046 for additional considerations when applying muting.

• 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 Muting Safety Module AI is designed IP54 dust ato 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 AI 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.

Technical specs

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.

Physical Interface

LED Indicators

Functionality

A safety fault on either Device 1 or Device 2 will immediately trigger and latch a fault on the Safety Out towards the MachineMotion AI controller. Except if in a muting state, a fault on either Device 3 or device 4 will immediately trigger and latch a fault on the Safety Out as well. The fault is latched until a reset signal is received.

The muting state is triggered when the corresponding A channel becomes triggered followed by the B channel. The sensors come from the muting kit (CE-AP-002-0000) and should be placed in a specific order to activate the muting for material.

Muting sensors A and B must be triggered within 2 seconds for the muting to occur. The order does not matter. Activating the muting sensors for more than 10 consecutive seconds will disable muting. The physical positioning of the sensors is critical for proper function and safety.

Port definitions and pinouts

Device 1 and Device 2 - M12, female, 12-pin, A-Keyed

The Device 1 and Device 2 ports connect to safety devices and will systematically trigger the Safety Out port. If any of these ports is unused, plug the included black jumper (CE-SA-125-0001).

Device 3 and Device 4 - M12, female, 12-pin, A-Keyed

The Device 3 and Device 4 ports also connect to safety devices and can be muted. If any of these ports is unused, plug the included black jumper (CE-SA-125-0001).

Muting 3A/3B & Muting 4A/4B - M12, female, 4-pin, A-Keyed

The Muting 3A/3B and Muting 4A/4B ports connect to a muting kit (CE-AP-002-0000). Triggering the sensors in a precise sequence will mute the associated Device port. If the muting function is not used, leave these ports unconnected.

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

The Safety Out port connects to the Safety In port of the MachineMotion 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).

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).

PNP Sensor Muting Configuration

When muting with Vention Muting kit (CE-AP-002-0000), please use the procedure below to configure the PNP sensors.

Important information

• The electronic fuse contained in the Muting Safety Module AI protects from internal faults and external faults, but only on the Device and Muting 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 port System 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.

For each of these functions performed by the Robot Safety Module, safety data can be found in the following table:
