TECHNICAL REFERENCE MANUAL 1 Introduction Measured distance Target Measuring reference The DLS-A(H) is a powerful distance measuring instrument for integration into industrial applications. It allows accurate and contact-less distance measurement over a wide range using the reflection of a laser beam: Fig. 1 Standard application Key features • Measurement range 0.2 to 200 m • Serial interface (RS232 and RS422) • Connection of up to 10 modules on a single RS422 line • Wide range power supply (9.
TECHNICAL REFERENCE MANUAL 1.1 Product identification The product is identified by the serial label on the top of the enclosure: Version Typical Accuracy 1.5mm 3.0mm Standard version DLS-A 15 Part No.: 500502 DLS-A 30 Part No.: 500501 Extended temperature range DLS-AH 15 Part No.: 500512 DLS-AH 30 Part No.: 500511 1.
TECHNICAL REFERENCE MANUAL 1.4 Measurement range The DLS-A(H) is an optical instrument, whose operation is influenced by environmental conditions. Therefore, the measurement range achieved in the application can vary.
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.
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.
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.
TECHNICAL REFERENCE MANUAL No. Action Save settings Comment The changed configuration must be saved to make it permanent. 5 Example for module 0: Save settings for module 0 Set automatic mode 6 Command s0s1) Set the DLS-A(H) to the automatic mode with the desired update rate. Example for module 0: Set measurement rate to fastest possible speed.
TECHNICAL REFERENCE MANUAL 3 Installation 3.1 Mounting Three M4 threaded holes in the bottom of the DLS-A(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 13 3.2 Device wiring 3.2.1 Cable connection A ferrite must be mounted to the connecting cable. Use a ferrite with a impedance of 150 Ω to 260 Ω at 25MHz and 640 Ω to 730 Ω at 100MHz. As example you can use SFC10 from KE Kitagawa.
TECHNICAL REFERENCE MANUAL 3.2.3 Controlled mode RS232 When using the RS232 interface only point-to-point communication is possible. ❢ Never connect multiple DLS-A(H)s on a RS232 serial line Host (PC or PLC) Tx 1 Rx Rx 2 Tx DLS-A(H) 9..30VDC 24..30VDC for DLS-AH 7,8 V+ 14,15 0V Fig. 4 Point-to-point connection with RS232 RS422 It is possible to connect multiple devices on a single RS422 line. To ensure proper operation, strict Master-Slave communication must be used.
TECHNICAL REFERENCE MANUAL 3.2.4 Automatic mode The analog interface of the DLS-A(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 smaller than 500 Ω. 13 DLS-A(H) 12 9 10 7,8 14,15 AO Analog Input 0..20mA AGND PLC 24V= DO 1 DO 2 V+ GND Digital Input 9..30VDC 24..30VDC for DLS-AH 0V Fig. 6 Connection of an instrument and a PLC 3.
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 σ, 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.
