Description

The infrared light curtain OPTIGUARD™ consists of a transmitter (TX) and a receiver (RX) edge, both of which have a built-in controller. These two active parts are electrically connected directly to the door drive unit of the elevator and mechanically mounted either to the car door faces and/or to the strike jamb.

The transmitter and the receiver edge build up a grid of infrared beams, which cover the door entrance to a height of 1,800 mm (6 feet). Due to the use of criss cross beams, the number of active beams used for the door protection is higher than the number of elements.

The transmitter and the receiver require a power supply of 14 to 30 VDC. The output of the receiver is a push/pull (PNP/NPN) stage, which is compatible with loads connected to either positive (PNP) or negative (NPN) power.

The Universal Power Supply (UPS) provides the power described above for the transmitter and receiver edges. It also includes a relay output that provides the N.O. or N.C. contact signal to the door operator circuit to reopen the elevator cab doors. The UPS accepts any voltage available from 20 to 265 VAC or VDC without any special wiring or adjustments. The polarity of DC voltage is irrelevant.

Installation of Transmitter (TX) and Receiver (RX)

The installation should be completed using the following sequence:

Mount the Transmitter and Receiver

The transmitter and receiver edges can be mounted either to the elevator cab doors (center-opening) or to the elevator cab door and the strike jamb (side opening).

The black “eyes” in the aluminum profile are the optical elements that form the front of the edge. This front side must face the companion piece, which is mounted on the opposite door or on the strike jam.

NOTE: The receiver (the edge with the blue connector) can be sensitive to "foreign" light. Avoid other sources of external light, including the transmitter of a different light curtain or single beam photo-electric system.

While the OPTIGUARD™ is designed to be tolerant of bright sunlight, it is better to mount the receiver so sunlight does not shine directly into the receiver lenses. This minimizes the possibility that the receiver will be “blinded” by direct sunlight.

Additional mounting hardware is included in the light curtain kit (e.g., mounting profiles, spacer profiles, and vision shields). Vision shields simply snap on over the transmitter and receiver to help protect them from damage.

The transmitter and receiver can be mounted directly to the elevator cab door or strike jamb, or the additional mounting hardware provided can be used to create a more aesthetic installation or fill large gaps that may exist between the elevator cab doors and the hoistway doors. The following illustrations provide examples of how this mounting hardware can be used:

Figure 1


UT-ID 3.4.6-1Page 7

NOTE: It is important that the alignment angle of the emitter to the receiver is less than ± 10° when the door is fully closed. We recommend that you keep this angle as close to zero as possible.

NOTE: It is important that the alignment angle of the emitter to the receiver is less than ± 10° when the door is fully closed. We recommend that you keep this angle as close to zero as possible.

NOTE: When using vision shields, you need to provide a minimal gap (see Figures 4–5) between the mounting profile of the light curtain and any perpendicular mounting surface immediately to the left or right of the mounting profile. Otherwise you will be unable to snap on the vision shield over the light curtain.

NOTE: The light curtain is designed to have high immunity to ambient light conditions (100,000 Lux). Avoid exposing the receiver unit to sources of light that exceed this value (e.g., strobe lights, other optical sensors, and direct sunlight) as it may be “blinded” by the light source.

Important Mounting Guidelines

It is also important to observe the following mounting guidelines:

• Never scratch or paint the optical lenses because they form the light path.

• Do not drill additional holes into the light curtain transmitter or receiver as this may cause internal damage to the device.

• Do not bend or twist the transmitter or receiver edges.

• Oil may damage the cable. Contamination must therefore be avoided at all times.

• Avoid external light from other infrared light sources like photo eyes, light barriers, or direct sunlight.

• For installation of the transmitter and receiver:

Exit both cables in the same direction.

Do not over-bend the cables or expose them to tension.

Ensure that the cables are away from AC main power or sources of high voltage.

Do not force, stretch, or squeeze the cables.

Ensure that the cable is well fastened and routed.

Keep the transmitter and receiver clean from dust and dirt.

Avoid contamination by oil or greasy liquids.

Avoid obstructions caused by objects entering the detection area.



February 2013


Cable Installation

CAUTION: Route cables properly to prevent damage.

The cables are color-coded. The transmitter cable features white connectors and the receiver cable features blue connectors. Make sure you connect the white cable ends together and the blue cable ends together. The transmitter and receiver cables are not interchangeable. If the white plug is connected to the blue connector (or vice versa), the system will not function correctly.

Route the cables properly using appropriate mounting material, neoprene cable ties, and cable guide wires.

CAUTION: If the cables are not properly fixed and guided, their lifetime could be reduced greatly. Cables can also be damaged due to swing or snag in the hoistway. Carefully follow the cable guide instructions, which can be found in this TIP.

Pay close attention to proper cable installation to ensure the highest possible reliability and lifespan of the light curtain. A properly installed cable will withstand more than 20 million door movements in applications where the light curtain is mounted on a moving door, while a poorly installed cable may break after less than 100,000 door movements.

Do not expose the cables to oil or other greasy liquids.

Ensure that the cable bending radii are greater than 3.2 inches (80 mm).

Universal Power Supply Installation

The universal power supply unit should be mounted in a convenient place on the car top. It can be mounted either horizontally or vertically using four mounting screws (see Figures 14–15).

CAUTION: The PCB is sensitive to electrostatic discharge and must be handled with care to prevent callbacks. Use anti-static procedures when handling it.

OBSTRUCTION IN OPENING

CAUTION: The maximum contact rating of the output relay is: • 250 VAC / 8 A

• 125 VDC / 0,5 A

• 30 VDC / 8 A

• min. 5 VDC / 10 m

When switching DC voltage loads higher than referenced here, use a pilot relay (not included).

Connect Light Curtain to Universal Power Supply

The light curtain system has two cables that connect the transmitter/receiver to the universal power supply.

1. Connect the blue receiver cable to the blue receiver cable receptacle on the receiver edge. Plug the 3-pin WAGO plug into the corresponding receptacle on the UPS control board.

2. Connect the white transmitter cable to the white transmitter cable receptacle on the transmitter edge. Plug the 2-pin WAGO plug into the corresponding receptacle on the UPS control board.

Power-Up and Test

Turn on power after the installation is completed. The LED indicators should have the following behavior:

• The green LED on the universal power supply should be illuminated when powered.

• The amber LED on the universal power supply indicates the status of the light curtain and the output relay. It should be illuminated when there is an obstruction and should be dark when the detection field is clear of obstruction.

• The green LED on the transmitter edge indicates that the transmitter is powered.

• The amber LED on the receiver edge indicates whether an obstruction of the detection field has occurred. It should be illuminated when there is an obstruction and should be dark when the detection field is clear of obstruction.

LED Indicator Meanings

Edge / UPS LED Color LED On LED Off

Receiver / UPS Amber

Power OK, Object Detected

or Not Aligned

No Power or No Object

Transmitter / UPS Green Power OK No Power

When the light curtain is obstructed during door closure, the obstruction should cause the doors to reopen.

Installation Tip

The UPS has a built-in buzzer feature. The buzzer can be left enabled or disabled. When the buzzer is switched on with the sliding switch located on the universal power supply, an obstruction is indicated by a buzzer signal. This feature may be helpful for troubleshooting, which is described in the next section.

Figure 12 provides basic connection and system behavior information.

Troubleshooting

If the light curtain does not operate as required:

1. Cycle power to the universal power supply.

2. Make sure you have connected the correct relay output for your application (i.e., NO vs. NC contact).

3. Check whether the green indicator LED in the transmitter edge is on. If not, verify that the cable connection between the UPS and the transmitter is secure.

4. Check whether the amber LED in the receiver edge is on. If so, make sure there are no obstacles between the transmitter and the receiver. If there are no objects, but the LED remains on, verify the cable connection between the UPS and the receiver is secure. If the output signal of the receiver is not stable during door closing, make sure that:

• The cables have not been routed near sources of electrical noise generated by a door drive or other device.

• No obstacles are entering the detection field during door closure.

• The edges are properly installed so that they cannot swing or vibrate, thus causing misalignment.

• The optical elements of the edges are clean and not covered by dust or dirt.
