Mode Switching Safety Module Datasheet

Overview

The Mode Switching Safety Module (CE-SA-018-0001) is ideal for situations where partial body entry into a machine is necessary, such as replacing a part during machine tending, without triggering an emergency stop (e-stop). The machine’s program can account for the time it takes to replace the part by incorporating this duration into the software. A safe sensor detects the end of a cycle and temporarily mutes light sensors for a few seconds until the operator completes the replacement. The next cycle then proceeds without an e-stop unless the operator’s hand enters the machine at any other time during the cycle, which would immediately trigger an e-stop. This module interfaces with up to four safety devices on MachineMotion V2, requiring at least two devices, with the unused ports populated with device jumpers. Every safety equipment deployment should be paired with a safety assessment to ensure risk reduction.

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 Mode Switching Safety Module may only be connected to the equipment listed in this manual.
• The Mode Switching 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.
• Mode switching is not designed for full body entry. As there is no latch on the monitoring of the safety device ports 1A and 2A, it is not acceptable to allow full body entry.
• When using the mode switching function, it shall be ensured that the safety device ports 1B and 2B represent the safe state of the application. As there is no latch on the monitoring of the safety device ports 1B and 2B, these safety inputs shall always be low if the machinery is in an unsafe state or location.
• 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 Smart 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 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

If device A and device B are triggered, a Safety OUT state will be triggered. The Safety OUT state is latched until a manual reset is engaged. There are two groups of mode switching (Zone 1 and Zone 2).

Port Definitions

Safety OUT - Pin-out - M12, male, 12-pin, A-Keyed

The Safety OUT port connects to the SAFETY IN port of another Safety Module (if daisy-chaining multiple safety modules) or to a MachineMotionV2.

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.

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