Safety

 

Undetected faulty operations, lack of alarms, lack of information for the operator and not understanding the operation of automated equipments are all major causes of accidents.

 

Unexpected conveyor start

 

Conveyors are among the devices that cause the most accidents. The following is a typical accident scenario:

 

Before reprogramming

 

1- The conveyor is stopped and there is no load on it.

2- The unaware operator walks by or even on the conveyor.

3- Doing so, he accidently activates a sensor.

4- The equipment starts and causes an accident.

 

After reprogramming

 

1- All the sensors are armed.

2- The conveyor only starts if one load is incoming from the previous station.

3- Equipment behaviour easily becomes predictable.

 

Unexpected equipment start

 

Before reprogramming

 

1- A mechanism jams and does not finish its stroke.

2- No alarm nor message is displayed on the screen.

3- The operator gets closer to identify the problem with the equipment.

4- The mechanism finishes its stroke and the equipment restarts unexpectedly.

 

After reprogramming

 

1- A mechanism jams and does not finish its stroke.

2- An alarm is triggered and displayed on the screen.

3- The operator knows exactly where the problem is and corrects the situation.

4- The operator resets the alarm and the machine restarts.

 

Useless product handling

 

Before reprogramming

 

1- A product is damaged by the equipment.

2- The operator withdraws the defective product.

3- After several attempts to restart the equipment, the operator must empty the machine to be able to restart it.

4- Loads are heavy and the operator strains his back.

 

After reprogramming

 

1- A product is damaged by the equipment.
2- The operator withdraws only the defective product from the machine.

3- The operator withdraws this product on the operator screen.

4- The equipment is ready to restart.

 

ReflexTM / QuadAlarmTM is a winning combination. Our customers see the difference and adopt our technology as a standard. To know the advantages of this method, click here.

 

Free demo

We have prepared a short demo with ReflexTM. This is done on a scaled down conveyor, with different sensors and actuators.

 

During the presentation, different programming methods of PLC are compared, including SFC and GRAFCET. Typical problems and machine safety will be discussed.

 

The presentation is a must for control engineers, directors of maintenance, operations and health & security departments.

 

This demo will catch your interest and shed new light on system programming.
