We design the safety of each machine end to end, from the sensor that detects the hazard to the stop that removes it, without guards that end up open or stops that halt the line for no reason. We start from the risk assessment and reach up to PLe per ISO 13849-1 and SIL 3 per IEC 62061.
Cuando la seguridad de una máquina falla, la consecuencia es un accidente, una máquina clausurada y una responsabilidad legal que recae sobre la empresa y sobre quien firmó la instalación. El error que más vemos en planta es creer que comprar componentes certificados alcanza. El nivel de seguridad lo da la cadena completa: un contactor sin monitoreo, un interruptor que se puentea con un actuador de repuesto o un rearme ubicado donde no se ve el riesgo bajan la función real muy por debajo de lo que dice el papel. La máquina “cumple” hasta el día del accidente.
We start from the risk, not from the catalogue.
We assess the machine per ISO 12100.
We define the PL or SIL each function requires.
Logic, detection and control with our partners' technology.
It is the last line of defence: it does not replace a guard, but it must be within reach the moment something goes wrong. On a compact machine, well-placed push buttons are enough; on a conveyor hundreds of metres long you need a rope that can be pulled from any point. What decides is the operator's distance to the hazard and that the stop stays latched until a manual reset.
A movable guard only protects if the machine knows it is open. If the hazardous part stops before someone can reach it, interlocking the door is enough; if it keeps running down by inertia, the door must stay locked until it stops. The selection criteria are stopping time versus access time, the coding level so it cannot be defeated, and the environment: vibration, washdown or dust.
When the operator enters many times per shift, a guard with a door slows production and ends up open. Non-contact detection protects without getting in the way: a barrier at the loading opening, a scanner watching the floor of a cell, or a radar where dust, steam or sparks blind an optical sensor. The safety distance is non-negotiable: the sensor must detect the person early enough for the machine to stop before they reach it.
This is where the decision is made whether the machine keeps running or stops. It receives dual-channel signals, detects wiring and device faults, and enables reset only when it is safe. For a few functions, fixed logic is enough; when there are many doors, zones and operating modes, a configurable controller that also tells the line PLC what tripped and where is the better choice.
Some tasks require entering the machine: changing a die, teaching a robot, cleaning or clearing a jam. The risk is someone energising it while a person is inside. It is solved with key-based access sequences that do not depend on electronics, enabling devices for working in service mode, and controls that require both hands outside the danger zone.
