ENFORCER E-931-S35RRQ Manual

Introduction

The ENFORCER E-931-S35RRQ Retro-Reflective Photoelectric Beam Sensor provides reliable sensing of objects that enter the space between the sensor and reflector, thus breaking the infrared beam. It is suitable for various types of such as detection such as sensing approaching vehicles to open a garage door or outdoor gate, as an entry notification for stores, for measuring parking distances, industrial automation, or an alarm notification, as well as many other uses.

Installation and Adjustment

LED Functions

• Red LED – When ON, indicates the sensor is triggered.
• Yellow LED – When ON, indicates the sensor is properly aligned with the reflector, and not triggered.

Understanding Sensing Range Adjustment

The Sensing Range adjustment determines the strength of the infrared signal emitted by the sensor.

• Min. Setting – Weakest infrared signal – sensor easily be triggered by small objects but more susceptible to false alarms
• Max. Setting (default) – Strongest infrared signal – sensor less likely to be susceptible to false alarms

Installation

1. Mount the reflector and the sensor so they face each other (see Mounting the Reflector, below and Mounting the Sensor).
2. Connect power to the sensor (see Wiring Diagram). The red LED will probably light, indicating that the sensor and reflector are not yet aligned. If the yellow LED lights (red LED OFF), it indicates that the sensor and reflector are aligned (though it may still be necessary to further adjust the alignment).
3. Turn the sensing range knob to Max.
4. To find the best alignment, slowly adjust the angle of the sensor (and/or reflector) up, down, left or right.

NOTES:

• Correct alignment is reached when the red LED is OFF and the yellow LED is ON.
• If both LEDs are OFF, the sensor is at the edge of signal range and may not work properly.

Adjusting Sensing Range

After the sensor and the reflector have been properly installed, the next step is to adjust the appropriate setting for the sensing range.

1. Starting from the Min. position, slowly turn the sensing range adjustment (see Fig. 2) clockwise until the yellow LED turns ON Mark this as position A.
   
   NOTE: If the yellow LED is on at the Min. setting, consider this as position A.
2. Place an object similar to what you desire to detect between the sensor and reflector at the point where you would normally want it to be detected. The yellow LED should turn off and the red LED should turn on.
3. Slowly turn the sensing range adjustment clockwise until the yellow LED turns on again. Mark this as position B.
   NOTE: If the yellow LED does not turn on even at the Max. position, then consider Max. as position B.
4. Turn the sensing range adjustment counterclockwise to a point approximately midway between points A and B.

Testing

1. Power up the sensor. The yellow LED should be ON and the red LED should be OFF.
2. Pass a typical object to be detected between the sensor and reflector. The red LED should turn ON and the yellow LED OFF indicating successful detection.

NOTE: If a shiny object, such as a chrome-plated item or one with reflective tape, comes in close proximity to the IR beam, the sensor may not be able to detect accurately. If so, you may need to adjust the sensing range counterclockwise until the desired results are obtained.
