At power-on the new crushing point protector OSW-3 runs an initialisation test of all its optical characteristics. They are: rubber quality, gate width, amount of bending of the sensor as well as dirt on the optical parts of the unit. The result of the test is displayed via a blinking code of 1 to 16 pulses directly at the sensor unit. When the unit is working properly, a yellow LED is activated.
