Protection Starts
With the System
Reliable machine protection is more than selecting a single component. System behaviour, environmental conditions, physical protection and integration all need to work together.
Define the Risk.
Then Define the Protection.
Protection decisions should start with how the machine is used, how it should behave when something goes wrong and what the operating environment demands.
Normal operation, foreseeable misuse and environmental conditions define the protection requirements.
Consider degraded operation, diagnostics, safe stop and failure containment early in the design.
Installation, service access, inspection and component replacement are part of a robust protection strategy.
Safety & Protection – a system perspective
Three Areas
That Need to Align
Robust machine protection connects system behaviour, environmental protection and the interfaces between mechanical and electrical subsystems.
System Behaviour
Define how the machine should behave during normal operation, abnormal situations and component failures.
- Operating scenarios
- Failure modes
- Diagnostics
- Safe and degraded operation
Physical & Environmental Protection
Components and enclosures need to withstand the environment in which the machine actually operates.
- Ingress protection
- Corrosion
- Vibration & shock
- Temperature & service access
Interfaces & Integration
Mechanical, electrical and subsystem boundaries must be considered together to achieve predictable behaviour.
- Signals & power
- Connectors & harnesses
- Mounting & sealing
- Assembly & maintenance
Protection in
the Real Machine
Enclosure selection is defined by the environment, installation, service requirements and the interfaces surrounding the protected electronics.
Environmental Protection
Enclosures can be selected around ingress, corrosion, vibration and temperature requirements while considering mounting, harness routing and service access.
Designed for Integration
Mounting, sealing, electrical interfaces and maintenance access should be defined as part of the machine architecture, not added as an afterthought.
Protection That Works
as Part of the Machine
The right solution depends on the machine, environment, operating scenario and integration constraints. Comtrium supports the discussion from requirements and component selection through practical machine integration.
