legrand HB300-B L1 High Bay Occupancy Sensor

Product Information

The HB300-B is a sensor module that operates on a voltage of 24VDC and has a power consumption of 7mA. It can be powered by the BZ power pack and can support up to 15 sensors. The coverage of the sensor depends on the type of lens attached to it. For more information about the coverage pattern, range, and density, refer to the HBLx Lens Coverage Guide.

Mounting Options

The HB300-B can be mounted directly to the fixture surface using two screw holes provided in the Power Module. Alternatively, it can be mounted using the HBNB3 back box and chase nipple. The Extender Module (HBEM3) allows for attaching the sensor to the side of the fixture in a number of configurations using provided chase nipples.

Wiring

The wiring diagram for the HB300-B is as follows:

Product Usage Instructions

1. Determine the appropriate mounting location for the sensor module based on the features of the power module and the coverage area. Ensure that the sensor is not obstructed by shelves or other objects.
2. Check if you have the necessary accessories for the sensor mounting configuration. Refer to Mounting Options for more information.
3. Assemble any necessary mounting accessories and attach them to the power module, making sure that the flying leads from the power module are accessible.
4. Connect the line voltage and load wires to the power pack leads as shown in the Wiring Diagram for the unit’s application.
5. Mount the sensor module using one of the mounting options described in Mounting Options.
6. The sensor is factory pre-set with PIR sensitivity set to medium 85% and time delay set using switches 3-7. Adjust these settings as per your requirements.

DESCRIPTION AND OPERATION

The HB300-B and HB300C-B occupancy sensors are designed for automatic lighting control in warehouse and high bay applications. They contain a passive infrared sensor (PIR) and are made up of two parts, a Power Module (HB300-B) and a Lens (HBLx). The coverage area is determined by the lens module. The lenses are interchangeable with any HB3xx series sensor. See the HBLx Lens Coverage Guide for more information.
The sensor model uses a set of DIP switches to set the time delay and PIR sensitivity. The HB300-B sensors operate at 24VDC and requires a Wattstopper power pack.
The HB300-B basic model provides a single output to the power pack, which is controlled only by occupancy.
The HB300C-B is for colder ambient temperature applications: -40° to 131°F (-40° to 55°C)

COVERAGE

Coverage patterns, density and range, are determined by the type of Lens attached to the HB300-B. For a complete description of each lens coverage pattern, see the HBLx Lens Coverage Guide.

INSTALLATION

1. Determine the mounting location appropriate to the features of the power module and the coverage area. Careful consideration must be given to sensor placement. Avoid placing the sensor where shelving or other obstructions may block the sensor’s line of sight.
2. Make sure that you have the appropriate accessories for the sensor mounting configuration. (See Mounting Options.)
3. Assemble any necessary mounting accessories and attach them to the power module, making sure that the flying leads from the power module are accessible.
4. Connect the line voltage and load wires to the power pack leads as shown in the Wiring Diagram for the unit’s application.
5. Do not allow bare wire to show.
6. Make sure all connections are secure.
7. Attach the Lens to the HB300-B as shown in Fig. 3.
8. Restore power from the circuit breaker.

WIRING

MOUNTING OPTIONS

The HB300-B can be attached either directly to the fixture surface via the two screw holes provided in the Power Module or using the HBNB3 back box and chase nipple. The Extender Module (HBEM3) allows attaching the sensor to the side of the fixture in a number of configurations using provided chase nipples.

Surface mounting requires holes in the fixture to pass wires and attach two No. 6 pan head sheet metal screws through the surface mounting screw holes on the component side of the Power Module as shown.

HBNB3 back box mounting requires a standard 1/2” knockout for the chase nipple. The box comes ready for side mounting. It can be modified for rear mounting as follows:

1. Pop out the cap in the rear knockout.
2. Un-snap the chase nipple from the side mount and snap intothe rear mounting hole.
3. Use the cap to close the side mount hole.
4. The chase nipple provided can be pushed into a standard 1/2”knockout in a metal fixture (max of 1 mm (0.04”) thick metal)without the need for the included internal nut. The nut can beused for added security if it is felt to be necessary.
5. The Power Module mounts to the back box with a bayonet typefitting requiring a slight twist of the units to lock them into place.

The HBEM3 extender module allows threading the wires through its chase nipples and into the fixture for connection. The two sides of the HBEM3 are then snapped together to protect the wires. The short chase nipple is designed to snap into the HBNB3 connection box while the longer chase nipple snaps into any metal fixture or connection box with a standard knockout. The caps on the HBEM3 can be removed in various configurations to allow moving the chase nipples and adjusting the height of the sensor on the fixture.

ADJUSTMENTS

The sensor is factory pre-set as follows:

• PIR Sensitivity (switches 1 & 2) Medium 85%
• Time Delay (switches 3-7) 15 minutes
• PIR Override (switch 8) OFF

PIR Sensitivity (Switches 1-2)
It may be necessary to adjust the PIR sensitivity if there is any environmental interference causing false triggers or if sensitivity needs to be increased for your particular application. The units are factory pre-set to medium, which should work in most applications. Change the switch settings to adjust sensitivity.

IMPORTANT START-UP INFORMATION

When the power module is installed and power is connected, the load comes ON and stays ON for 50 seconds. This warm-up period only occurs during installation or after a power failure of 5 minutes or more.

• If the sensor detects occupancy during the warm-up, the lights stay ON as long as it continues to detect motion, plus the Time Delay.
• If no occupancy is detected during the warm-up, the light turns OFF after the initial 50 second warm-up period.

TROUBLESHOOTING

During the sensor warm-up period, which can last up to a minute after power is applied to the power module (or after a power outage of 5 minutes or more), the load can be either ON or OFF, depending on the status of the relay before the sensor was powered down. After warm-up, the sensor will open or close the relay to correspond to the occupancy status of the room.
To quickly test the unit, turn the time delay to minimum. Wait for the warm-up period to end. Move out of the sensor’s view. Lights should turn OFF after 15 seconds. Move into the sensor’s view. The sensor’s Red LED should blink and the lights should turn ON.

Red LED on power module does not blink:

Check sensor wire connections. Verify the red and black wires are tightly secured.

Red LED blinks but lights do not turn ON:

1. Make sure that power to the sensor has been ON continuously for at least one minute, then
   • Turn OFF power to the sensor.
   • Check control wire (blue or violet) connection.
   • Turn ON power to the sensor.
   • The load should come ON. If not, continue with step 2.
2. Check power connections to the light fixture.

Lights will not turn OFF:

1. If there is no motion from people or equipment in the sensor’s view but the red LED blinks, look for any nearby source of IR energy in motion, such as turbulent air from a heating or cooling supply, or other sources. Divert the air supply away from the sensor, or move the sensor.
2. Verify time delay. The time delay can be set from 15 seconds to 30 minutes. Ensure that the time delay is set to the desired delay and that there is no movement within the sensor’s view for that time period.
3. Check DIP switch 8 setting. If it is ON, it overrides the PIR function and keeps the load ON.
4. Check sensor wire connections. Verify control wire (blue or violet) is secure
