Compressed air is one of the most important types of energy. Even smallest leaks can lead to high costs in the course of time. Compressed air losses in a robot cell with different tools are to be minimised. The compressed air supply consists of two compressed air circuits (6 and 12 bar), which are to be monitored separately. In case of compressed air losses, an error message is to be sent to the maintenance staff.

In both compressed air lines, compressed air meters of the type SD8000 are
installed. They continuously monitor the compressed air consumption - during production as well as in quiescent condition. There are limit values for both operating states. An error message is generated when the limits are exceeded.

Not only the energy costs could be reduced by monitoring the compressed air. The purchase of another compressor was no longer necessary and an existing compressor could be switched to standby. Installation and purchase of the compressed air meter is paid off in no time.

For security reasons, the maximum permissible angles of rotation on the different axes of an industrial robot are monitored. So far, roller level switches have been used in conjunction with switching cams. Disadvantage: The mechanics are subject to wear and often have to be readjusted in a complicated way. The task was a low-cost retrofitting to electronic sensors, possibly as a complete set in modular design.
Geri dönüşüm
Fail-safe inductive sensors of the types GG505S and GG507S were used,
connected to the existing PILZ controller. Position detection of the switching cams is carried out without contact. One sensor replaces two roller lever switches. A total of four axes is monitored in this way.

The solution has proved its worth: Due to the elimination of mechanical components the position detection is now wear-free. Readjustment is no longer necessary, which leads to an increase in plant uptime. Retrofitting with the sets was quick and easy. The solution can be flexibly extended as the application changes.

The task here is to monitor high speed doors with a safety switch. To avoid unnecessary loss of time, the safety switch should enable the next step before the door reaches the end stop.
Geri dönüşüm
Instead of a mechanical safety switch, an electronic fail-safe sensor type GM701S is used here. Advantage: it does not need a special coded target for a reliable switching. Using a longer target the safe state is detected well before reaching the end position. The subsequent clamping processes are already started when shutting the gate.

By means of a simple design feature the process cycle time was reduced by three seconds - while maintaining the degree of safety. This means a greater productivity in terms of quantities as compared to the old detection system that uses mechanical safety switches.
