r-PA Series Safety Light Curtain is designed to protect machine operators and plant personnel from hazards associated with moving machinery with fail-safe control reliability. In operation, r-PA extends a collimated “Curtain of Light” in front of hazardous areas. If a worker’s hand interrupts the “light curtain”, a signal is sent to the “stop” circuit of the machine. r-PA is designed with fail-safe circuitry, if any component within the system fails, a stop command is sent to the press, disabling it until the failure is corrected.

Features

Self-diagnosis function at power-up
At power-on, self-diagnosis is performed for about 1 second
When no abnormality is found, the sensor immediately starts to operate normally.
Error-mode Monitor
When an error arises, its cause is indicated with LED flashing patterns.
Mutual-interference Preventive Function
When 2 sensors are so close to be mutual-interference, it’s prevented with making mutual-interference
preventive connection.
Ambient-light Diagnosis Function
With modulated light system, it’s mostly unaffected by ambient-light
Also, it turns to be lock-out state when detecting external abnormal light.
External Diagnosis Function (Emitting Stop)
Stops emitting of the emitter forcibly.
It’s effective when pre-operation check of the safety system.
Both-Side Protection
Control box (option) is selectable from one-side and both-side types.
The both-side type enables to control 2 pairs of emitters and receivers simultaneously.
