Caution Modiﬁcation to the instrument may only be carried out by trained personnel that are authorized by Radac BV. Failure to adhere to this will invalidate the warranty and the approval certiﬁcate. Warning In hazardous areas it is compulsory to: •...
Page 7: Positioning
Positioning For obtaining the best results from each WaveGuide sensor, the following positioning criteria must be taken into account: • It is advised to choose a mounting position such that the WaveGuide radar beam is free of large reﬂecting obstacles (the beam of the F08 antenna can be approximated to a conical shape having a 5 [deg] half top angle as shown...
Page 8 • The point array is the recommended conﬁguration in most situations. For that pur- pose a 10 [deg] radar mounting frame WG5-MPD10-CP can be supplied by Radac. Here the three radars are mounted on a single frame. One radar is looking vertically downwards.

Figure 1.4: Top view of the three radar positions labeled A,B Upon request, Radac can provide the mounting plates alone and C in an anticlockwise se- (product no. WG5-MPD10-CP) or the mounting plates to- quence. In this case the labels apply to the physical radars and gether with a mounting frame (product no.
Page 11 The optional point array mounting frame (product no. WG5-MPD10-CP) consists of three parts as shown in ﬁgure 1.6. The mounting frame should be installed on two horizontal beams (the horizontal beams are not included in the mounting frame package). Note: when designing and producing the horizontal mounting beams, enough horizontal distance should be left between the radars and the structure they are mounted to.
Page 12: The Line Array
A mounting plate can be used to ﬁx each radar to two horizontal beams at the desired location (an example sketch of such a plate is given in Fig. 1.9). Upon request, Radac can supply such a mounting plate (product no. WG-MP-SS). During installation it is advised to install the mounting plate ﬁrst and secondly install the radar.
Page 13: The Triangle Array
A mounting plate can be used to ﬁx each radar to two horizontal beams at the desired location (an example sketch of such a plate is given in Fig. 1.11). Upon request, Radac can supply this mounting plate (product no. WG-MP-SS). During installation it is advised to install the mounting plates ﬁrst and secondly install the radars.

Chapter 2 Wiring Block diagram Figure 2.1: Block diagram of the Waveguide 5 Direction-Onboard 2. The three sensors A, B and C are connected to the local network as well as the processing unit. This diagram assumes the processing unit and the radars to be powered by a single power supply.

• The cable must be shielded and can have a maximum length of 80 [m]. Upon request, Radac can supply an optional cable that complies with the WaveGuide system require- ments for power and data transmission. The terminal compartment contains a six pole and a two pole connector as well as a ground connection point, as shown in Fig.
Page 16 Note Connecting the Reset poles for for 0.5 to 2 seconds during operation will cause the sensor to temporarily use the default IPV4 address 192.168.111.71 until the system is rebooted. Connecting the Reset poles for longer than 10 seconds during operation will cause the sensor to reset to default factory settings and reboot.

Chapter 3 WaveGuide system commissioning With all system components correctly connected as described in the previous chapter, the processing unit can be conﬁgured using the following steps (explained in the current chapter): 1. Connect the WaveGuide processing unit to a computer. 2.
Page 19: Step 1. Connect The Waveguide Processing Unit To A Computer
Step 1. Connect the WaveGuide processing unit to a computer Once the WaveGuide system is connected to a Local-Area-Network, communication can be done via the available web interface (Fig. 3.1). For this purpose any web browser with JavaScript enabled can be used. Figure 3.1: The web-interface of the WaveGuide processing unit.

Step 3. Conﬁguration The conﬁguration page contains ﬁve sections as listed in Table 3.2. Link Description Date&Time For viewing and setting the system time. Network For viewing and changing the network settings. Sensor For viewing and changing the sensor speciﬁc settings and for view- ing reﬂection diagrams.

network that includes a time server, then the system can be adjusted to synchronize time and date with the local time server using the "Set NTP" button and submitting the local NTP server address. Step 3.2: Adjust network settings Figure 3.4: Adjusting the network settings. The network settings can be modiﬁed via the web-interface (Fig.
Page 23: Step 3.3: Sensor Configuration
Step 3.3: Sensor conﬁguration Figure 3.5: Sensor conﬁguration menu. The WaveGuide Direction-OnBoard 2 is designed with a high level of ﬂexibility in mind, to apply to every possible mounting situation. The sensor menu allows the conﬁguration of those parameters that are speciﬁc to the sensor installation (Fig. ??). During the installation process it is important to register the position of each of the three sensors.
Page 24 Figure 3.6: Preview of the array orientation based on user input. The mounting height above the reference water level, and possibly a number of other parameters, needs to be set for each speciﬁc mounting location. This can be done in the conﬁguration table that is shown in Fig.
Page 25 Max. Range The range maximum in [m] is the maximum distance at which the sensor will detect the water level. In general there is no need to modify this parameter. Yet in some situations it is advised to set this parameter to a value lower than two times the distance from the radar to the lowest expected water level.
Page 26: Step 4: Perform A System Check
Step 4. Perform a system check This section explains how to inspect the quality of measurements after conﬁguring and rebooting the WaveGuide processing unit (the start-up process can take up to 5 minutes): Step 4.1: Check the system information page The system information table can be reached through the status menu item on the right top.
Page 27: Step 4.2: Check The Reflection Diagrams
Step 4.2: Check the reﬂection diagrams The reﬂection diagram for each sensor can be accessed via the sensor conﬁguration page by clicking on the corresponding "reﬂection" button (Fig. 3.9). A reﬂection diagram is a graphic representation of a 25 [ms] scan, where the signal strength [dB] is plotted against the measurement distance [m].
Page 28: Step 4.3: Check Measurements
Step 4.3: Check the measurements On the ’Dashboard’ page, the heave parameter shows data measured during the last 1, 3 or 10 minutes. Please inspect the available heave and slope graphs to visually conﬁrm the measured data. From the same menu all calculated parameters are available. Please take into account that it can take up to 10 minutes to gather enough raw data to calculate the parameters.
