Figure 4: Distance to reflecting surfaces It is thus important to respect a minimum distance between the AOPD and reflecting surfaces. The minimum distance, D , depends on: • operating distance between transmitter (TX) and receiver (RX) • effective aperture angle (EAA) of the AOPD: For a Type 4 AOPD, EAA = 5°...
The formula to get for a Type 4 AOPD: (m) = 0.15 for operating distance < 3 m (m) = 0.5 × operating distance (m) × tan (2α) for operating distance ≥ 3 m Warning! If the reflecting surface is the floor, whatever the calculated D , the minimum installation distance to the floor must still be respected, see chapter “Minimum installation distance”.
Figure 7: Minimum distance to an adjacent device as a function of the operating distance The formula to get for a Type 4 AOPD: (m) = 0.3 for operating distance < 3 m (m) = operating distance (m) × tan (2α) for operating distance ≥ 3 m Warning! Please note that TX can interfere with RX in the same way as TX...
Figure 8: Installation of several devices close to each other 4.2.5 Transmitter and receiver orientation The two units shall be assembled parallel to each other and with the markings on active and passive units on the same side, both up or both down for example.

Figure 10: Use of deviating mirrors Note! The following precautions must be respected when using the deviating mirrors: • The alignment of the transmitter and the receiver can be a very critical operation when deviating mirrors are used. Even a very small displacement of the mirror is enough to loose alignment.
Checks after first installation Control operations to carry-out after the first installation and before machine start-up. The controls must be carried-out by authorized personnel, either directly or under the strict supervision of the person in charge of machinery safety. Check that: •...

Alignment procedure The alignment between the transmitter and the receiver is necessary to obtain the correct functioning of the AOPD. A good alignment prevents outputs instability caused by dust or vibrations. The alignment is perfect if the optical axes of the first and the last beams of the transmitter coincide with the optical axes of the corresponding elements of the receiver.

• Fix the two units firmly using pins and brackets. • Disconnect the power supply. • Re-connect the power supply. • Check that the green LED on the receiver is on when the beams are not interrupted. Then check that the green LED ( ) turns off and the red LED ( ) turns on when one single beam is interrupted.
Functions Dip-switch selectable functions A slot situated on the front side of the receiver (see Figure 18) and easily opened with a screwdriver, facilitates the access to the internal dip-switches. Dip-switches Figure 18: Location of the dip-switches Figure 19: Lock over the dip-switches To open the lid, insert the tip of a flat screwdriver into the groove of the hinged lid and lever it up slightly until the snap happens.
Configuration at delivery The device is supplied with the following configuration: Muting timeout = 10 min T/X-muting EDM deactivated Automatic Reset Note! The Muting function can only be activated if the muting sensors are properly connected to the Muting A and Muting B inputs and if one of the lamps operates correctly.
Figure 21 below illustrates how Automatic Reset and Manual Reset work: Figure 21: Automatic/Manual Reset The selection of the Manual/Automatic Reset function is made with the dip-switches placed under the lid on the receiver: dip-switches 4 and 8 must be ON for the Automatic Reset function and OFF for the Manual Reset function.
Figure 23: Time chart of the Acknowledge function EDM function The AOPD has a function for monitoring actuation external devices (EDM). This function can be activated or deactivated. Figure 24: Dip-switches 3 and 7 OFF to activate the EDM function To use this function correctly: •...
Figure 26: Time chart of the EDM function and T are the times between the change of state of the OSSD outputs and the change of state of the NC contact of the external device. ≤ 200 ms: the external NC contacts must open within this time after the OSSD outputs have switched ON.
8.6.1 Typical muting application and connection of the AOPD Figure 28: Typical muting application The figure above shows a typical muting application: the box on the conveyor may go through the AOPD without stopping the machine but the worker may not. Following a correct activation sequence of the A1, B1, A2 and B2 sensors, the AOPD is temporarily bypassed.
Page 31
Figure 29: Integrated lamp • When the Muting function is on, the integrated lamp on the top of the receiver is on and the lamp output (pin 8) is driven. • If both the integrated lamp and the external lamp are broken and/or not connected, the muting request causes the AOPD to enter Error mode and the OSSD outputs to switch off.
NORMAL OPERATION OSSD ON Figure 30: The muting lamp is on when the muting function is activated 8.6.2 Muting direction The AOPD can be used with: • T/X-muting when the “boxes” can move in both directions. This is the default setting. T-muting demands four muting sensors and X-muting only two.
8.6.3 T/X-muting Suitable when the objects/”boxes” can move in both directions. This is the default setting: Dip-switches 2 and 6 ON for T/X-muting Figure 31: • T-muting demands four muting sensors, A1, B1, A2 and B2. • X-muting demands two muting sensors, A1 and B2. The sensors named A1/A2 are connected to MUTING A and the sensors named B1/B2 are connected to MUTING B.

D must be less than L, D < L d1max [cm] = V [m/s] × T max [s] × 100 d2max [cm] = V [m/s] × T max [s] × 100 Note! Guidance in the positioning of the muting sensors can be found in IEC/TS 62046.
8.6.4 L-muting Suitable only when the objects/“boxes” move in one direction. Figure 34: Dip-switches 2 and 6 OFF for L-muting • L-muting demands two muting sensors, A and B. The sensor named A is the farthest from the AOPD and must be activated first. If the sensor named B is activated first, the Muting function is not activated.

Override The override function is used to bypass the AOPD completely and switch on the OSSD outputs when it is necessary to start the machine despite one or more beams of the AOPD being interrupted. The purpose is usually to clear the detection zone and move a “box” that has stopped there because of a cycle anomaly.
8.7.1 Override at start-up • Switch off the power supply. • Restore the power supply and press the RESET button after approx. 5 s but within 9 s and keep it pressed for at least 5 s. The OSSD outputs switch on and remain activated for a maximum time of 600 s.
8.7.2 Override at run time • One or both muting inputs must be active. • Press and release the RESET button 3 times < 1 s. The OSSD outputs will be activated for more than 2 s and 600 s max. •...
Diagnostic functions Visualization of the status of the AOPD The operator can check the status of the AOPD using four LEDs on the receiver and two LEDs on the transmitter (Figure 40). Figure 40: LED display on the receiver and the transmitter LEDs on the transmitter •...

Periodical checks The following is a list of recommended checks and maintenance operations that should be periodically carried-out by authorized personnel. Check that: • The AOPD remains in OSSD OFF state ( ) during beam interruption along the entire detection zone, using the suitable “Test Piece” and following the Figure 11 scheme (see chapter “Checks after first installation”).
Device maintenance Orion2 Base light grids do not require special maintenance operations. To avoid the reduction of the operating distance, optic protective front surfaces must be cleaned at regular intervals. Use soft cotton cloths damped in water. Do not apply too much pressure on the surface to avoid making it opaque.
