Residual hazards

Danger from electric current
Contact with energized parts poses an immediate risk of fatal injury from electric shock.

Opening the housing, servicing, mainenance and/or repairing electrical components of Wandelbots NOVA, e. g. on the physical instance/IPC, may only be executed by authorized and specifically qualified electricians. Defective components must always be exchanged.

Before working on or in the event of defects of electrical components of Wandelbots NOVA, the following measures must be taken immediately:

1. Disconnect all electrical components (switch off the voltage);
2. Secure all electrical components against being switched on again;
3. Ensure the absence of voltage within the electrical components.

Protection against network overload caused by the installed robot application must be ensured by qualified electric personnel.

Appropriate protective measures (such as overcurrent, surge devices and residual current protection devices) must be implemented for the connections of the electrical power supply of Wandelbots NOVA.

Ensure there is sufficient train relief in moving cables

Danger caused by robot
Improper assessment by the integrator of the application-specific hazards can result in people being crushed, drawn in or caught due to the robot's complex movement sequences.

The system integrator must assess the hazards on an application-specific basis and define the required safety functions.

The system integrator must integrate safety functions (especially for "Manual mode with reduced speed" operating mode with enabling switch, operating mode selection by key switch) in accordance with the requirements of EN ISO 13849-1:2015 and EN ISO 10218-2 (5.6.4 Manual operating mode).

Protection from access to the robot in the form of fixed or movable separating protective devices in compliance to EN ISO 13857:2019 and EN ISO 14119:2013 or non-separating (non-contact) protective devices in compliance to EN ISO 13849-1:2015 as well as EN ISO 13855:2010 and EN 61496-1:2013 must be in place.

The following protective measures must be in place:

• Protection from access to security settings on the robot manufacturer's original control panel with a password.
• Protection against unauthorized operating mode switching.
• Movement limits with safety levels or protection zones.
• Implementation of a suitable EMERGENCY STOP concept.

For industrial robots:

• In "Manual with reduced speed" operating mode, the robot's speed is max. 9.84 in/s.
• In "Manual with reduced speed" operating mode, enabling functions for robot movements.

Danger caused by robot
Misuse can cause the robot to move unexpectedly and people can be crushed, pulled in or caught.

• Inspect the motion group id that is indicated in the Robot Pad.
• Only execute controls if the motion group's indicated name matches the desired robot's name and if you visually monitor the area of risk.

Danger caused by robot
Accidentally mixing up HMIs to control the robot can cause unexpected robot movements. People can be crushed, pulled in, or trapped.

Danger caused by moving parts
If devices fail to stop moving parts safely in case of malfunctions and emergencies, people can be crushed or hit.

• Only use Wandebots NOVA with machinery with a suitable EMERGENCY STOP concept, stop functions and only with a regularly inspected EMERGENCY STOP function.

Danger caused by cables, hoses and pipes
People may slip, trip or fall over improperly laid cables, hoses and pipes.

• Lay permanently installed cables, hoses andpipes safely and without affecting the operating paths and transportating routes.
• Remove temporarily laid cables, hoses and pipes after completing all tasks and store them in a safe place.
• Cables, hoses and pipes always have to be laid flat on the floor.

Material damage due to improper utilization of Kontron IPC
The physical instance Kontron IPC is equipped with IP2X protection. Operating this physical instance in industrial environments without additional protection against dirt or soiling can result in damage to the IPC.

• Protect the IPC sufficiently against dirt or soiling when operating in industrial environments or clean it on a regular basis.

Danger caused by robot
When controlling the robot through Wandelbots NOVA with faulty robot safety settings, the robot can move at high speed. People can be crushed or hit.

• Always adjust the robot's speed according to the situation.
• Adhere to the robot's speed limits. For more information refer to the robot manufacturer's original operating instructions.

For industrial robots:

• In "Manual with reduced speed" operating mode, all movements controls executed by with Wandelbots NOVA will be executed in reduced speed.
• In "Manual with reduced speed" operating mode, the robot's speed is max. 9.84 in/s.

Material damage due to misuse
Misuse of Wandelbots NOVA may cause material damage.

• Wandelbots NOVA with physical industrial robots may only be used in the "Manual with reduced speed" operating mode.
• All Wandelbots NOVA components must be sufficiently visible from the user's location during usage.
• Prevent operating or control errors.

• If an EMERGENCY STOP was triggered, it must be reset and the safety functions confirmed manually. After confirming the safe status of the area of risk, communication must be reactivated between Wandelbots NOVA and the robot control.
• If an EMERGENCY STOP was triggered, the program's execution will be stopped immediately. Refer to the robot manufacturer's documentation for more information on stop categories. As soon as the EMERGENCY STOP trigger reason has been eliminated, the restart must be confirmed manually.
• Safety functions (in particular for industrial robot's "Manual with reduced speed" operating mode with enabling switch, operating mode selection by key switch) must be present in compliance with the requirements of EN ISO 13849-1:2015 and EN ISO 10218-2.
• Inspecting and testing of work equipment or operating resources may only be executed by qualified personnel, fulfilling the TRBS 1203 or TRBS 1201- Part 1 requirements.

The work place's emission sound pressure level is lower than or equals 70dB(A).

• If any defects are identified, inform your superior.
• In the event of malfunctioning, resume operating Wandelbots NOVA only after all robot application defects have been professionally remedied or eliminated and its original intended state has been restored.
• After defects have been remedied or eliminated, responsible qualified personnel has to inspect and confirm the proper functionality of safety functions.

The interfaces to be used between Wandelbots NOVA and the physical robot controller are defined by Wandelbots GmbH.
