1.4 Measuring range The DLS-C(H)/FLS-C(H) is an optical instrument, whose operation is influenced by environmental conditions. Therefore, the measuring range achieved in use may vary. The following conditions may influence the measuring range: Key Factors increasing range Factors reducing range Target surface Bright and reflective surfaces such as the target plates (See Accessories) Matt and dark surfaces Green and blue surfaces Airborne particles Clean air Dust, fog, heavy rainfall, heavy snowfall Sunshine Darkness Bright sunshine on the target The measurement range may be influenced by configuring different measurement modes. See 8.3.2 Enhanced measuring Modes (sNuc) on page 25. The DLS-C(H)/FLS-C(H) does not compensate the influence of the atmospheric environment, which may be relevant when measuring long distances (e.g. > 150m). These effects are described in: B.Edlen: “The Refractive Index of Air, Metrologia 2”, 71-80 (1966) 1.5 Prevention of erroneous measurements 1.5.1 Rough surfaces On a rough surface (e.g. coarse plaster), measure against the center of the illuminated area. To avoid measuring to the bottom of gaps in the surface use a target plate (see accessories) or board. 1.5.2 Transparent surfaces To avoid measuring errors, do not measure against transparent surfaces such as colorless liquids (such as water) or (dust-free) glass. In case of unfamiliar materials and liquids, always carry out a trial measurement. ) Erroneous measurements can occur when aiming through glass panes or if there are several objects in the line of sight. 1.5.3 Wet, smooth, or high-gloss surfaces 1 Aiming at an “acute“ angle deflects the laser beam. The DLS-C(H)/FLS-C(H) may receive a signal that is too weak (error message 255) or it may measure the distance targeted by the deflected laser beam. 2 If aiming at a right angle, the DLS-C(H)/FLS-C(H) may receive a signal that is too strong (error message 256). 1.5.4 Inclined, round surfaces Measurement is possible as long as there is enough target surface area for the laser spot. On irregular and round surfaces the arithmetic average of the illuminated surfaces will be measured. 1.5.5 Multiple reflections Erroneous measurements may occur if the laser beam is reflected by other objects than the target. Avoid any reflective object along the measurement path. Distance Laser Sensor Page 6/41

2 Device setup We recommend that you carry out the configuration steps in an office before mounting the device, especially if you are not familiar with the DLS-C(H)/FLS-C(H). The DLS-C(H)/FLS-C(H) supports two types of operating modes: • Controlled mode (Host controlled) • Automatic mode (for use in stand-alone operation) The first decision to be taken is the type of operating mode that will be used to transmit the distance measurement data. While the controlled mode provides maximum flexibility and accuracy, it is often not suitable for integration into existing PLCs or analog environments. In such cases the automatic mode might be preferred. Influence factors controlled mode automatic mode (with analog and/or digital outputs) Accuracy Maximum measurement accuracy Accuracy depends on signal scaling (see 8.3.6 Set/Get distance range (sNv) on page 27) Flexibility Access to full command set Limited Integration Requires protocol implementation Wiring of AO and/or DO signals Connection Connection of up to 10 DLS-C(H)/FLS-C(H)s to a single RS-422 line. Point-to-point connection The following two sections describe the configuration of the DLS-C(H)/FLS-C(H) for the controlled and automatic modes. 2.1 Connection To be able to configure the DLS-C(H)/FLS-C(H), it must be powered and connected to a PC. Figure 2 shows the necessary connections. On the PC, any terminal program can be used to communicate with the module. A configuration utility is also available on the web page www.dimetix.com.

2.2 Controlled mode In controlled mode, each operation of a DLS-C(H)/FLS-C(H) is triggered by a command sent from a host system over a serial line. While a single device can be connected to the host system using the RS232 interface, up to 10 devices can be connected to a single serial RS422 line. The related command set is described in Chapter 8 on page 20. 2.2.1 Configuration After connecting the module, the steps below are necessary to configure the DLS-C(H)/FLS-C(H) for the controlled interface mode. No. Action Comment Command 1 Set ID switch Changes to the module ID are activated after a power cycle. Example for module 0: Change the ID Switch to position 0 Set ID switch to position 0 Power OFF; Wait 10s; Power ON 2 Set controlled mode Set the DLS-C(H)/FLS-C(H) to the controlled mode, if not already in controlled mode. Example for module 0: Set to controlled mode by means of the stop command. s0c1) 3 Set communication parameters If necessary, change the settings for the serial interface. Example for module 0: Set serial interface to 19200 Baud, 8 Bit, no Parity s0br+21) Power OFF; Wait 10s; Change settings on the host; Power ON 1) Commands are described in 8 Command set on page 20 Note: If the communication parameters of the module are lost, please reset the configuration to the factory settings (7 Factory settings on page 19) using the reset button (5.2 Reset switch on page 16). Please note that the ID switch must be reset manually. 2.2.2 Host software Host software is required for operation of the DLS-C(H)/FLS-C(H) in controlled mode. When connecting multiple devices to a single serial line (RS422), strict Master-Slave communication must be implemented (DLS-C(H)/FLS-C(H) operates as slave). For software sample-code or application-notes please consult our web site www.dimetix.com. Careful testing of the host software together with the devices prior to installation is strongly recommended. Distance Laser Sensor Page 8/41

2.3 Automatic mode An automatic mode is provided for host-less operation of the DLS-C(H)/FLS-C(H). The analog and digital outputs are updated according to the configuration described below as soon as the unit is powered off and on. Analog Output The analog output is configurable and works with two ranges: – 0..20mA – 4..20mA Digital Outputs Three digital outputs are included in the DLS-C(H)/FLS-C(H). Two are programmable, while the third is used to signal an error state of the device. 2.3.1 Configuration After connecting the module, the following steps are necessary to configure the DLS-C(H)/FLS-C(H) for automatic mode. No. Action Comment Command 1 Set current output range Defines the current output range from 0 to 20mA or from 4 to 20mA. Example for module 0: Set current output range from 4mA to 20mA. s0vm+11) 2 Set distance range Defines the minimum distance (Dmin) and the maximum distance (Dmax) for the current range of the analog output. Example for module 0: Set distance range from 0m to 10m s0v+00000000+001000001) 3 Set analog output in case of an error Sets the current that should be applied in case of an error. Example for module 0: Set current to 0mA in case of an error. s0ve+0001) 4 Configure digital output Set the ON and OFF level for the digital outputs. Example for module 0: DO 1: off=2000mm on=2005mm DO 2: off=4000mm on=4005mm s01+00020000+000200501) s02+00040000+000400501) 5 Save settings The changed configuration must be saved to make it permanent. Example for module 0: Save settings for module 0 s0s1) 6 Set automatic mode Set the DLS-C(H)/FLS-C(H) to the automatic mode with the desired sample rate. Example for module 0: Set sample rate to fastest possible speed. s0A+01) 1) Commands are described in 8 Command set on page 20 Note: If the serial line settings of the module have been lost, please reset the configuration to the factory settings (7 Factory settings on page 19) using the reset button (5.2 Reset switch on page 16). Please note that the ID switch must be reset manually. Distance Laser Sensor Page 9/41

2.4 Display Mode If Display Mode is enabled, the DLS-C(H)/FLS-C(H) formats the measured distance as ASCII string, which is understood by External Displays with a serial interface. Since the DLS-C(H)/FLS-C(H) outputs this formatted string automatically on the serial interface after completing a measurement. Measurement results can be displayed on an external display without an additional controller. For a detailed description of this mode, please contact Dimetix or your dealer. 2.5 External Trigger The DLS-C(H)/FLS-C(H) includes the option of triggering measurements with an external switch or push button on Digital Input 1 (DI 1). Using the Digital Input DI 1 disables the Digital Output DO 1. The command to activate the external trigger option is described in 8.4 Digital Input on page 30. 2.5.1 Configuration After connecting the DLS-C(H)/FLS-C(H), the following steps are necessary to activate the external trigger. The example shows the configuration for triggering a single distance measurement. No. Action Comment Command 1 Activate digital input DI1 Defines the action for a trigger event on DI1. Example for module 0: Configure DI1 to trigger a single distance measurement. s0DI1+21) 5 Save settings The changed configuration must be saved to make it permanent.

3 Installation 3.1 Mounting Three M4 threaded holes in the bottom of the DLS-C(H)/FLS-C(H) make it easy to mount the device. Always obey all applicable safety regulations and never use the device outside the specifications stated under 4 Technical data on page 14. 3.2 Device wiring 3.2.1 Power Supply For trouble-free operation use a separate power supply for the DLS-C(H)/FLS-C(H). FLS-C, DLS-C: 9...30V, 0.5A DC FLS-CH, DLS-CH: 24...30V, 2.5A DC 3.2.2 Cable connection A ferrite core must be fitted to the connecting cable. Use a ferrite core with an impedance of 150 Ω to 260 Ω at 25MHz and 640 Ω to 730 Ω at 100MHz. For example you can use KCF-65 from KE Kitagawa. 3.2.3 Shield and Ground The DLS-C(H)/FLS-C(H) contains two electrically isolated grounds, the general ground (GND) and the analog ground (AGND). GND and AGND are connected to the housing by a RC element. Please see figure 3 Distance Laser Sensor Page 11/41 DLS-B(H) Fig. 3 Connection between shield and ground Screw terminal GND AGND 15 pin D-Sub GND AGND 20nF 1M 10nF 500k

3.2.4 Controlled mode RS232 Only point-to-point communication is possible when using the RS232 interface. Never connect multiple DLS-C(H)/FLS-C(H)s on a RS232 serial line RS422 It is possible to connect multiple devices on a single RS422 line. To ensure proper operation, strict Master-Slave communication must be applied. It is important, that the Master has full control of the communication and never initiates a new communication before termination of the previous communication (answer from the DLS-C(H)/FLS-C(H) or timeout). Ensure, that all DLS-C(H)/FLS-C(H)s are set to different ID numbers Distance Laser Sensor Page 12/41 Fig. 4 Point-to-point connection with RS232 DLS-B(H) DLS-C(H) FLS-C(H) Fig. 5 Connecting multiple devices with RS422 DLS-C(H) / FLS-C(H) R+ R- T+ T- ID switch Position 0 A B A B Host (PC or PLC) Rt Rt 5 4 6 3 14,15 Rt Rt 7,8 V+ R+ R- T+ T- ID switch Position 1 5 4 6 3 14,15 7,8 V+ R+ R- T+ T- ID switch Position 9 5 4 6 3 14,15 7,8 V+ 9..30VDC 24..30VDC with Heating 0V (slave) (slave) (slave) (master) DLS-C(H) / FLS-C(H) DLS-C(H) / FLS-C(H) Tx Host (PC or PLC) Rx Tx Rx 2 7,8 1 14,15 V+ 9..30VDC 24..30VDC with Heating 0V

3.2.5 Automatic mode The analog interface of the DLS-C(H)/FLS-C(H) is isolated from the rest of the device. When using the analog interface, connect the analog ground (AGND). Make sure, that the total resistance in the analog path is lower than 500 3.3 Alignment of the laser beam Alignment of the laser beam is often difficult when the target is far away, as the laser spot is not visible. An optional telescopic viewfinder is available which simplifies the alignment significantly.

4 Technical data 4.1 Measuring accuracy The measuring accuracy corresponds to the ISO-recommendation ISO/R 1938-1971 with a statistical confidence level of 95.4% (i.e. ± twice the standard deviation σ, refer to diagram on the right). The typical measuring accuracy relates to average conditions for measuring. It is ±1.0mm for the FLS-C(H) 10, ±1.5mm for the DLS-C(H) 15 and ± 3.0mm for the DLS-C(H)/FLS-C(H) 30 valid in the tracking mode. Maximum deviation may occur under unfavorable conditions such as bright sunlight or when measuring to poorly reflecting or very rough surfaces. Measuring accuracy may deteriorate by approximately ±0.02mm/m for distances above 30m. The DLS-C(H)/FLS-C(H) does not compensate changes of atmospheric environment.

8.3.2 Enhanced measuring Modes (sNuc) Multiple measuring modes available in the FLS-C measuring devices meet different requirements for various applications. With these measuring modes measuring rate and accuracy can be optimized for special requirements. The FLS-C measuring device has with factory settings an accuracy of ±1 mm (FLS-C(H) 10) respectively ±3 mm (FLS-C(H) 30) at 2σ. Measuring rate depends on environmental conditions such as target surface, distance, background light (e.g. sun light), etc. Good environmental condition increase measuring rate (e.g. white target surface or orange reflective target plate and dark environment). Measuring Mode overview Mode Measuring rate σ Typical accuracy @ 2 Characteristics Application examples FLS-C(H) 10 FLS-C(H) 30 Normal (factory settings) max. 10 Hz1) ±1 mm ±3 mm Measuring range on natural surface: typical 65 m Various Fast max. 20 Hz1) ±2 mm ±6 mm Increased measuring rate up to 20 Hz.

8.3.3 Set automatic mode (sNA) This command activates the automatic mode of the DLS-C(H)/FLS-C(H). It triggers continuous measurement of the distance. The analog, digital and SSI outputs are updated according to the measured distance values. The sampling time defines the measurement rate. If the sampling time is set to zero, the measurements are executed as fast as possible (depending on target conditions). The automatic mode is active until the STOP/CLEAR command (sNc') is issued. The operating mode is stored in the DLS-C(H)/FLS-C(H) and activated immediately. This mode is also activated after next power ON. Internally, “tracking with buffering” is started (command sNf). Therefore, the last measurement can also be read out from the module with the command sNq. Command Command sNA+xxxxxxxx Return successful gNA?

8.3.7 Set/Get digital output levels (sNn) Sets the distance levels at which the digital outputs are switched ON and OFF with a hysteresis. Two different situations are possible: ON level > OFF level The ON level of the hysteresis is larger than the OFF level. With an increasing distance, the digital output is switched on (open drain output is closed) when the distance exceeds the ON level. With a decreasing distance, the digital output is switched off (open drain output is open) when the distance falls below the OFF level. ON level < OFF level The ON level of the hysteresis is smaller than the OFF level. With a decreasing distance, the digital output is switched on (open drain output is closed) when the distance falls below the ON level. With an increasing distance, the digital output is switched off (open drain output is open) when the distance exceeds the OFF level.
