Frequently Asked Questions
Below we've compiled the most common questions and answers regarding this product.
How is the r-tec safety photocell (IR40) connected and aligned?
The photocell is mounted as a transmitter (TX) and a receiver (RX) on either side of the passage, aligned to see each other (range 25 m). The transmitter only takes power (+/−); the receiver has power (+/−) and a relay output (COM/NC/NO) connected to the photocell input of the control board. The supply is 12/24 V AC/DC. If the photocells do not see each other, first check the alignment and cables; on automatic-door units the line is verified with the photocell test button.
