Micro controller based laser beam supervision Scanner Safety 4.xx USB / RS232 for 6 color channels
It is at any time possible that your laser soft- or hardware fails in such a way that dangerous laser beams go into your audience. This can be avoided only with a scanner safety.
Standing or slowly moving rays, which can damage the human eye, are hidden. The safety monitors the system to technical defects.
In X and Y direction, the limits of the range are set, where the laser beam must have a minimum speed. If the beam in this area, a CPU monitors the safety requirements. If the specifications are not achieved, the safety shuts down all 6 color channels.
If the laser is dark / blanked, the CPU detects this condition and allows the shutdown passive.
A watchdog monitors the CPU and switches optionally after 0.01 seconds the laser dark.
The power supplies are patrolled internally within limits.
8 Seconds after applying a voltage the Safety is ready to work.
When booting the Safety a green LED will flash and the laser output remains dark.
In operation and sufficient scanner movement, the green LED will stay on permanently.
The red LED is indicating if the movement is inadequate and the Safety intervenes.
In case of failure the LCD lighting is turned on at the same time like the red LED.
