4 Proper use MagicWatch MWE850 (item number: MWE-850-4DSM) is an ultrasonic reverse warning system. When reversing, it monitors the space behind the vehicle and provides an audible and visible warning signal for any obstacles it detects. Since MWE850 is designed merely as an additional aid for reversing, it does not relieve you of the duty to take proper care when reversing. MWE850 is designed for installation in cars. 5 Technical description

5.1 Functional description

MagicWatch MWE850 consists of four built-in sensors, a display for visual warning signals, and a piezoelectronic speaker for audible warning signals. The piezoelectronc speaker is fitted on the parcel shelf or boot cover. The display can be mounted on the dashboard, on the rear view mirror on the windscreen or on the boot cover. It measures distances based on the echo time principle. The four sensors constantly emit ultrasonic signals when you reverse. The sensors contain both transmitters and receivers, and capture any ultra- sonic signals reflected by obstacles. The distance to the obstacle is calcu- lated using the echo time, and signalled by the speaker using a sequence of impulse tones. The closer the obstacle approaches, the faster the succes- sion of warning tones. The DSM (digital signal memory) function creates a space profile during the measurement, which records any small fixed objects (such as trailer cou- plings). This means these are not signalled as obstacles. The system only signals an obstacle when the space profile changes. The display signals the position of the obstacle using two LEDs. A numerical display shows the distance in 10 cm increments. The sensors are installed on the bumper. The sensors may be painted. WAECO recommends having the sensors painted by a specialist workshop. Since the sensors are equipped with their own amplifiers, you can extend the connection between the sensors and the controller to up to 10 m. MWE-850-4DSM.book Seite 35 Mittwoch, 23. Mai 2007 4:35 16Technical description MagicWatch MWE850

Only use WAECO cables. Otherwise, proper operation cannot be guaranteed. Defective sensors can be replaced without removing the bumper. There is a plug connector just behind the sensor for this.

The detection range of MWE850 is divided into three zones (see fig. 5, page 5): z Zone 1 This zone is the first limit range. Small or objects with poor reflective char- acteristics are sometimes not detected in this zone. z Zone 2 Nearly all objects are displayed in this zone. z Zone 3 Nearly all objects are displayed in this zone, but some objects may come into the blind spot of the sensors. Situations may arise where MWE850 does not detect objects or fails to signal their distance correctly, due to their physical charac- teristics. Note the four following examples. Example 1 (see fig. 6, page 5) Objects which do not enter the detection area of the sensors cannot be recorded. Example 2 (see fig. 7, page 5) The distance to objects with large gaps in them may not be correctly sig- nalled. In the example, A is not signalled, but only B or C instead. Example 3 (see fig. 8, page 5) For diagonal obstacles, the shortest distance A is signalled. MWE-850-4DSM.book Seite 36 Mittwoch, 23. Mai 2007 4:35 16MagicWatch MWE850 Technical description

Example 4 (see fig. 9, page 6) In this case, MWE850 displays the distance A. As the vehicle approaches the audible indicator goes over to the stop zone, and as it approaches further, the distance A goes into the blind spot, so that MAGIC WATCH signals the dis- tance from point B. Caution! As these four examples show, situations can arise where the device fails to display an object or does not display the shortest distance. The device does not relieve you of your obligation to take special care when reversing. Therefore, always be extremely careful when reversing. If an object enters the blind spot of the sensors, MWE850 automat- ically shows the distance to the next object. This means the piezo- electronic speaker changes from fast to medium beeps and the dis- play shows a different distance. In this case, always stop the vehicle immediately and check the sit- uation. The DSM function ensures that objects attached to the vehicle (such as trailer couplings) are not classified as obstacles. As a rule they do not pro- trude more than 0.3 m over the sensors. They are therefore in the close area (zone 3) of up to 0.3 m, in which MWE850 gives a stop warning and where you should stop (see the “Testing functions” on page 44 section). Caution! If loads or objects on the vehicle protrude over the close area of 0.3 m, there is a danger of accidents. An obstacle can collide with the load or the object before it is detected by the sensors in the close area and MWE850 gives a stop warning (see fig. 11, page 6). MWE-850-4DSM.book Seite 37 Mittwoch, 23. Mai 2007 4:35 16Installing MWE850 MagicWatch MWE850

For installation and assembly you require the following tools: z Drill bit set (see fig. 1.1, page 3) z Drill (see fig. 1.2, page 3) z Screwdriver (see fig. 1.3, page 3) z Set of ring or open-ended spanners (see fig. 1.4, page 3) For making and testing the electrical connection the following tools are required: z Diode test lamp (see fig. 1.5, page 3) or Voltmeter (see fig. 1.6, page 3) z Crimping tool (see fig. 1.7, page 3) z Insulating tape (see fig. 1.8, page 3) z Cable bushing sleeves, if required To secure the controller and the cable you may require additional screws and cable binders.

6.2 Fitting the sensors

The sensors must be correctly aligned for the device to work. If these point to the ground, bumps in the ground may be inter- preted as obstacles. If they point too far up, obstacles will not be detected. Note the following information during installation: z The maximum range is approximately 1.5 m. z So that the corners of the vehicle (indicator lights etc.) can be monitored, the sensor should not be fitted more than 0.3 m away from them. z The distance from the sensors to the ground must be between 40 cm and 50 cm (see fig. 10, page 6). z The installation location should be as flat as possible so that the cover ring of the sensor is on the bumper. MWE-850-4DSM.book Seite 38 Mittwoch, 23. Mai 2007 4:35 16MagicWatch MWE850 Installing MWE850

The sensor is preset to have a vertical installation angle of approximately +5°. This means that the cover ring is thicker at the bot- tom. Note that the sensors must be aligned in a particular direction. The top of the sensor is marked with a ▼ (see fig. 12.1, page 6). z Fit the sensors at regular intervals along the total width of the vehicle in order to guarantee the optimum monitoring. z The sensors may be painted. WAECO recommends having the sensors painted by a specialist workshop. The installation procedure is as follows: ➤ Choose an installation location on the bumper which is as perpendicular to the road surface as possible (see fig. 12, page 6). When fitting the sensors, make sure that the coupling of the sup- ply line can be reached outside the hole. This ensures that if you have to replace the sensors you do not have to take off the bum- per (fig. 20, page 9). z If the sensor cable is not long enough, you can order one-metre extension cables (MWCS-1) as accessories. Caution! Before making any drill holes, ensure that no electrical cables or other parts of the vehicle can be damaged by drilling, sawing and filing. ➤ For each sensor, drill a hole in the bumper with a diameter of 22.5 mm (22.5 mm core bit supplied). ➤ For a more accurate fit, slant the drill downwards slightly when drilling the hole on the inside of the bumper. The sensor cover can now be easily inserted at a downward angle. ➤ Guide the cables of the sensors through the corresponding hole. ➤ Insert each sensor into the corresponding drill hole until it latches into place.

6.3 Laying the sensor extension cables

When laying cables, ensure that: z They are not kinked or twisted z They do not rub on edges z They are not laid in sharp edged ducts without protection (see fig. 3, page 4). z The plugs must be connected with the correct polarity. A blocking pin pre- vents reverse polarity (see fig. 13 A, page 6). z Make sure the locking pin catches (see fig. 13 A, page 6). Only then is trouble-free operation guaranteed. To release the connection press the holder and pull the plug and socket apart (see fig. 13 B, page 6). z If the sensor cable is not long enough, you can order one-metre extension cables (MWCS-1) as accessories. Note The extension cables are marked: L (left), CL (centre left), R (right), CR (centre right). This marking helps you connect them to the control electronics to ensure that the display is correct. Caution! Before making any drill holes, ensure that no electrical cables or other parts of the vehicle can be damaged by drilling, sawing and filing. ➤ Take suitable precautions to protect holes made in the bodywork from water penetration, for example by spraying the cable and the sleeve with sealant. ➤ Where possible, use existing rubber bungs in the boot for laying the extension cables. If there are no rubber bungs, make a suitable hole with a diameter of around 13 mm and insert a cable sleeve. Note Pull the plugs of the extension cables through the cable sleeve before inserting the sleeve in the body work. MWE-850-4DSM.book Seite 40 Mittwoch, 23. Mai 2007 4:35 16MagicWatch MWE850 Installing MWE850

➤ Lay out the extension cables in the boot so that they cannot be damaged under any circumstances (e.g. by flying grit). ➤ Carefully fasten the extension cables behind the bumper. ➤ Insert the sensor plugs into the sockets of the corresponding extension cables (see fig. 16 A, page 8).

6.4 Fastening the control electronics

Note the following information when selecting a place to fit the control elec- tronics: z Note the length of the sensor cables. z The control electronics may not be damaged if you have luggage or objects in the boot. ➤ Fasten the control electronics to a suitable place in the boot. The control electronics should not be exposed to any moisture. Note The extension cables are marked: L (left), CL (centre left), R (right), CR (centre right). This marking helps you connect them to the control electronics to ensure that the display is correct. These markings can also be found on the control electronics. The plug polarities cannot be reversed: They can be only be plugged into the connection in one way. ➤ Insert the plugs of the sensor extension cables into the corresponding sockets on the control electronics (see fig. 16 B, page 8). Make sure the locking pin catches. MWE-850-4DSM.book Seite 41 Mittwoch, 23. Mai 2007 4:35 16Installing MWE850 MagicWatch MWE850

Note the following information when selecting a place to fit the display: z Note the length of the display cable. Note that the boot cover swings upwards on vehicles that have a big tail- gate. z The display must be easily visible when you are reversing. z The display must not be covered or damaged by any objects placed on the boot cover. z Fit the display so that there is no danger of injury, for example when sharply braking. z Its compact design means it can be fitted in many places in the vehicle. Good positions at the front are (see fig. 14, page 7): – Above the rear view mirror – On the dashboard – On the ceiling – On the window beside the wing mirror Good positions to the rear are (see fig. 15, page 8): – On the boot cover – On the ceiling – Next to the window – On the C pillar ➤ Pull off the protective foil and stick the display in a suitable position. Note The extension cables are marked: L (left) and R (right). This marking helps you connect them to the control electronics to ensure that the display is correct. These markings can also be found on the control electronics. The polarity of the socket cannot be reversed: They can be only be plugged into the connection in one way. ➤ Insert the display plug into the socket of the corresponding extension cable (see fig. 16 A, page 8). ➤ Guide the extension cable to the control electronics and insert the socket of the extension cable into the connection on the control electronics (see fig. 16 B, page 8).

6.6 Installing the speaker on the boot cover

The piezoelectronic speaker should be glued to or mounted on a suitable place on the boot cover. Note the following information when selecting the installation location for the piezoelectronic speaker: z Note the length of the speaker cable.Note that the boot cover swings upwards on vehicles that have a big tailgate. z The piezoelectronic speaker must not be covered or damaged by any objects placed on the boot cover. z You can set the volume to either off (Off), low (Lo), or loud (Hi), using the switch on the front of the speaker. ➤ Insert the socket of the piezoelectronic speaker into the plug of the exten- sion cable (see fig. 18 A, page 8). ➤ Guide the extension cable to the control electronics and insert the socket of the extension cable into the connection on the control electronics (see fig. 18 B, page 8). ➤ Remove the protective foil and affix the speaker ... ➤ Or attach it using suitable screws.

6.7 Connecting the control electronics

Caution! Make sure the polarity is correct. On some vehicles, the reversing light only works when the ignition is switched on. In this case, you must switch on the ignition in order to identify the positive and negative wires. ➤ Connect the red cable (fig. 19.2, page 8) on the control electronics to the positive wire (+) of the reversing light (fig. 19.1, page 8). ➤ Connect the black cable (fig. 19.3, page 8) to the earth wire (–) of the reversing light or to earth (bodywork). MWE-850-4DSM.book Seite 43 Mittwoch, 23. Mai 2007 4:35 16Testing functions MagicWatch MWE850

7Testing functions Conduct the functional test as follows: ➤ Switch on the ignition and engage reverse gear. Be very careful when you first operate the device, and make sure you get to know the various sequences of beeps. In Zone 3 it can occur that obstacles are not detected, because they are no longer within range of the sensors (depending on design). The device is equipped with a diagnostic function: If the sensors are defec- tive, you will hear three short beeps when you engage reverse gear. Zone Description (see fig. 5, page 5) Sound sequence LEDs 1 MWE850 recognises obstacles from a distance of around 1.5 m (measured from the sensor) and signals them with a series of slow beeps from the speaker and by the illumination of the green LED group. Beep Beep Beep Green 2 From a distance of around 0.95 m (measured from the sensor) MWE850 switches to the green LED group and to the medium beep sequence. Beep Beep Beep Beep Beep Yellow 3 At a distance of around 0.3 m (measured from the sensor) and below, MWE850 switches to the red LED group and the the continuous tone. When you reach this zone, stop the vehicle. Otherwise you might damage the vehicle or the obstacle. Beeeeep… Red MWE-850-4DSM.book Seite 44 Mittwoch, 23. Mai 2007 4:35 16MagicWatch MWE850 Using MWE850

8Using MWE850 MWE850 is activated automatically when you engage reverse gear with the ignition on or the motor running. As soon as there is an obstacle within the detection range, a repeated signal tone sounds and the green LEDs light up. As you reverse, the sequence of beeps changes according to the zone you are in, thus indicating the distance (see “Testing functions” chapter on page 44). The display also modifies as the zones change. Be very careful the first time you use the system, until you are familiar with the various sequences of beeps and the display. Caution! Stop the vehicle immediately and check the situation (getting out if necessary), if the following happens while you are reversing: The device first shows an obstacle while you reverse, and the beeps speed up as normal (i.e. from slow to medium). Suddenly the beeps become slow again or no obstacle at all is shown. This means that the original obstacle is in the blind spot of the sen- sors (depending on the design), and you might hit it. Caution! If loads or objects on the vehicle (e.g. bicycle racks) protrude over the close area of 0.3 m, there is a danger of accidents. An obstacle can collide with the load or the object before it is detected by the sensors in the close area and MWE850 gives a stop warning (see fig. 11, page 6). 9 Maintaining and cleaning MWE850 Caution! Do not use sharp or hard objects to clean the device as these may damage the sensors. ➤ Clean the sensors with a damp cloth from time to time. MWE-850-4DSM.book Seite 45 Mittwoch, 23. Mai 2007 4:35 16Searching for errors MagicWatch MWE850

10 Searching for errors The device indicates no function. The cables to the reversing light are not connected or are switched. The plug for the display is not connected or is not properly plugged into the control electronics. The plugs for the sensors are not connected or are not properly plugged into the control electronics. ➤ Check the plugs, and plug them in so that they latch in place. A defective sensor is indicated (three beeps when you engage reverse gear) If a defective sensor is indicated (see “Testing functions” chapter on page 44), this is what to do: ➤ Park the vehicle about a metre away from a large obstacle, such as a garage door. ➤ Engage reverse gear. ✓ The slow beeps sound (Zone 1, see fig. 5, page 5) and the green LEDs of the intact sensors light up. ➤ Then stand in front of each sensor in succession. ✓ The beeps speed up. The beeps do not change on the defective sensor. 11 Guarantee Our general guarantee conditions apply.
