Therefore, the measurement range achieved in the application can vary. The following conditions may influence the measurement range: Key Target surface Airborne particles Sunshine Factors increasing range Factors reducing range Bright and reflecting surfaces such as the Matt and dark surfaces target plates (See 9 Accessories on page 32) Green and blue surfaces Clean air Dust, fog, heavy rainfall, heavy snowfall Darkness Bright sunshine at target The DLS-A(H) does not compensate the influence of atmospheric environment, which may be relevant when measuring long distances (e.g. > 150m). This 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 plaster joints use a target plate (see accessories) or board. 1.5.2 Transparent surfaces To avoid measuring errors, do not measure towards transparent surfaces such as colorless liquids (such as water) or (dust free) glass. For unfamiliar materials and liquids, always take a trial measurement. ) Erroneous measurements can occur when aiming through panes of glass, 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-A(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-A(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. 1.5.5 Multiple reflections Erroneous measurements can occur in the case that the laser beam is reflected from other objects than the target. Avoid any reflecting object along the measurement path. Distance Laser Sensor Page 5/40 https://manual-hub.com/ TECHNICAL REFERENCE MANUAL 2 Device setup We recommend performing the configuration steps in an office before mounting the device, especially if you are not familiar with the DLS-A(H). The DLS-A(H) supports two types of operation modes: · Controlled mode · Automatic mode The first decision to be taken is the type of operation 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. Key Accuracy Flexibility Integration Connection controlled mode automatic mode (with analog output and digital outputs) Maximum measurement accuracy Accuracy depends on signal scaling (see 8.3.5 Set distance range (sNv) on page 23) Access to full command set Limited Requires protocol implementation Wiring of AO and DO signals Connection of up to 10 DLS-A(H)s to a Point-to-point connection single RS-422 line. The following two sections describe the configuration of the DLS-A(H) for the controlled and automatic modes. 2.1 Connection To be able to configure the DLS-A(H), it must be powered and connected to a PC. Figure shows the necessary connections. On the PC, any terminal program can be used to communicate with the module. Additionally, a configuration utility is available on the web page www.dimetix.com. COM1 or COM2 Default setting: Baud: Bit: Parity: Stop: 19200 7 even 1 Tx 3 Rx 2 Gnd 5 9 pin D-Sub 1 2 14,15 7,8 15 pin D-Sub Rx Tx GND V+ -+ 9..30VDC 24..30VDC for DLS-AH Fig. 2 Connection for DLS-A configuration DLS-A(H) Distance Laser Sensor https://manual-hub.com/ Page 6/40 TECHNICAL REFERENCE MANUAL 2.2 Controlled mode In controlled mode, each operation of a DLS-A(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 19. 2.2.1 Configuration After connecting the module, the steps below are necessary to configure the DLS-A(H) for the controlled interface mode. No. Action 1 Set ID switch Comment Changes of the module ID are activated after a power cycle.

Example for module 0: Set to controlled mode by the stop command. s0c<trm>1) If necessary, change the settings for the serial interface. Example for module 0: Set serial interface to 19200 Baud, 8 Bit, no Parity s0br+2<trm>1) Power OFF; Wait 10s; Change settings on the host; Power ON 1) Commands are described in 8 Command set on page 19 Remark: If the communication parameters of the module are lost, please reset the configuration to the factory settings (7 Factory settings on page 18) using the reset button (5.2 Reset switch on page 15). Please note that the ID switch must be reset manually. 2.2.2 Host software Host software is required for operation of the DLS-A(H) in controlled mode. When connecting multiple devices to a single serial line (RS422), strict Master-Slave communication must be implemented (DLS-A(H) operates as slave). Please consult the Dimetix web page for application notes. Careful testing of the host software together with the devices prior to installation is strongly recommended. Distance Laser Sensor https://manual-hub.com/ Page 7/40 TECHNICAL REFERENCE MANUAL 2.3 Automatic mode The automatic mode is provided for host-less operation of the DLS-A(H). The analog and digitals outputs are updated according the configuration described below as soon as the unit is powered up. 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-A(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-A(H) for the automatic mode.

The DLS-A(H) has an adapter for mounting a telescopic viewfinder that simplifies alignment significantly. Please refer to chapter 9 Accessories on page 32 for a description of the viewfinder. Distance Laser Sensor https://manual-hub.com/ Page 12/40 TECHNICAL REFERENCE MANUAL 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 , refer to diagram on the right). The typical measuring accuracy relates to average conditions for measuring. It is ±1.5mm for the DLS-A(H) 15 and ± 3.0mm for the DLS-A(H) 30 valid in the tracking mode 99.7% 95.4% The maximum measuring error relates to unfavorable conditions such as: - Highly reflecting surfaces (e.g. reflector tapes) - Operation at the limits of the permitted temperature range, adaptation to ambient temperature interrupted - Very bright ambient conditions, strong heat shimmer and can be up to ± 2 mm for DLS-A(H) 15 and ± 5 mm for DLS-A(H) 30. The DLS-A(H) does not compensate changes of atmospheric environment. This changes can influence the accuracy if measuring long distances (>150m) at conditions very different to 20°C, 60% relative humidity and 953 mbar air pressure. The influences of the atmospheric environment is described in B.Edlen: "The Refractive Index of Air, Metrologia 2", 71-80 (1966) Distance Laser Sensor https://manual-hub.com/ Page 13/40 TECHNICAL REFERENCE MANUAL 4.2 Specifications Typical measuring accuracy for DLS-A 15 / DLS-AH 15 1) DLS-A 30 / DLS-AH 30 1) Maximum measuring accuracy for DLS-A 15 / DLS-AH 15 1) DLS-A 30 / DLS-AH 30 1) Smallest unit displayed Measuring range on natural surfaces Measuring range on brown (reflecting) target plate Measuring reference Diameter of laser spot at target at a distance of Time for a measurement Single measurement Tracking Light source Laser Life Time 3) ESD EMC Power supply Dimensions Temperature range during operation 2) DLS-A 15 / DLS-A 30 DLS-AH 15 / DLS-AH 30 Temperature range during storage Degree of Protection Weight Interface ± 1.5 mm @ 2s ± 3.0 mm @ 2s ± 2.0 mm ± 5.0 mm 0.1 mm 0.2 to 30 m ca. 20 to 200 m from front edge (See 6 Physical dimensions) 6mm @ 10 m 30mm @ 50 m 60mm @ 100 m 0.6 to ca. 5 sec 0.6 to ca. 5 sec Laser diode 620-690 nm (red) IEC 60825-1:2001; Class 2 FDA 21CFR 1040.10 and 1040.11 Beam divergence:0.16 x 0.6 mrad Pulse duration: 15x10-9 s Maximum radiant power: 0.95 mW Maximum radiant power per pulse: 8mW Measurement uncertainty: ±5% >25'000h @ 25°C IEC 61000-4-2 : 1995 EN 61000-6-4 EN 61000-6-2 9 ... 30V DC 0.5A for DLS-A 24 ... 30V DC 2.5A for DLS-AH (Heating option) 150 x 80 x 55 mm -10 °C to +50 °C -40 °C to +50 °C -40 °C to +70 °C IP65; IEC60529 (protected against ingress of dust and water) DLS-A: 630 g DLS-AH: 680 g 1 serial asynchronous interface (RS232/RS422) 1 programmable analog output 0/4 .. 20mA 2 programmable digital outputs 1 digital output for error status 1) See 4.1 Measuring accuracy on page 13. 2) In case of permanent measurement (tracking mode) the max. temperature is reduced to 45°C 3) 500 1000h at 50°C.
