Installation

Important Safety Precautions:

• Do not touch un-insulated cables unless they are disconnected upstream.
• Do not install the sensor during storms with lightning.
• If the cable is subjected to flexing, use a coiled section with a bending radius that prevents 90-degree bends.

Installation Steps:

1. Install the photocell vertically with the bracket, at a height of 20cm.
2. Power on the photocell to determine the position of the reflector.
3. Ensure there is no obstruction between the photocell and the reflector.
4. Fix the reflector when the working light of the photocell is Green.

Wiring Connection

Terminal Definitions:

• TS (#1): No use. Terminal for factory testing.
• AC10-25V DC12-30V (#2 & #3): Power Input (10-25VAC or 12-30VDC). Polarity does not matter for DC power.
• NO (#4): Output contact. Normal open when the photo beam is aligned. Normal closed when the photo beam is obstructed.
• NC (#5): Output contact. Normal closed when the photo beam is aligned. Normal open when the photo beam is obstructed.
• COM (#6): Common Output contact.

Note: When connecting to a TOPENS gate opener, refer to its user manual. For other brands, confirm the power output and photocell input terminals. If the gate opener lacks a suitable AUX power output, a separate power supply for the sensor is required.
