Light Curtain Power Failure & Forced Power-on Protection

OTCP2 controller identifies safety travel signals and offers two selectable modes, A and B. In mode A, the light curtain provides full-range protection; in mode B, the cam switch signal blocks the light curtain signal, eliminating protection during the return stroke. The OTCP2 controller has no function switch, providing both power-off protection and forced power-on protection, thus avoiding safety hazards caused by not using photoelectric protection devices.
