Page 5: General Information
Thanks to the fail-safe design of the hardware, and the software’s continuous checks of all safety- related functions, the D-LX 100 meets the European standards EN 230 (oil) and EN 298 (gas), as well as technical guidelines for steam boilers TRD 411 to 414 and TRD 604 for intermittent, continuous and 72-hour operation. -

Page 7: Functional Description
DURAG also offers a D-LX 100 flame scanner employing a UV photocell, which can monitor flames in the UV-C range, where wavelength is very short. In this range it is unnecessary to suppress any non- dynamic flame energy. -
Page 8: Self-Check
If employed for continuous operation, any component failure that jeopardizes the safety-related functions of a scanner must trigger an error shutdown. The D-LX 100 is therefore equipped with a dual-channel microprocessor system. -
Page 9: Installation
LED’s will blink alternately. Pressing the reset button on the front panel of the D-LX 100 acknowledges a fault in the unit and allows flame scanning functions to continue after restart. When the reset button is pressed, all LEDs will go off. -
Page 10: Start-Up
The 6° angle of view should always be oriented toward the root of the flame, that is, the bottom third of the flame. The D-LX 100 is mounted onto a sighting tube with a 1¼” pipe (male thread connection). -
Page 11: Setting The Flame Recognition Threshold
LED goes out (flame intensity current is less than 8 (or 5) mA). Once the scanner’s alignment and flame recognition threshold have been properly determined, the D-LX 100 must reliably report if a burner is shut down or if an impermissible deterioration of the flame image occurs. Consideration must be given in order that ambient light sources do not generate faulty system status. -

Page 15: Infrared Flame Scanner
Compared to a UV flame scanner, however, it is more sensitive to ambient light. A silicon photo element with a spectral sensitivity of λ= 300 nm to 1100 nm is used in the D-LX 100 IS. This flame scanner detects visible light. If the flame is red or gold in color, it is ”visible” to the scanner, on the pre-condition, however, that there is movement in the flame, i.e., the flame is dynamic. -

Page 24: Cable And Shielding
D-LX 100 10.9. Cable and Shielding The D-LX 100 is designed for the connection of 230 VAC via the fault contact and flame contact, while the system operates in the low-voltage 24 VDC range. If the contacts are to be used in the ”high-voltage” 230 VAC range, either an appropriately insulated cable must be used to cover the entire distance from the flame scanner, or a distributor panel needs to be installed, with separate cables used after it. -
Page 25: Maintenance And Service
If the outside of the lens regularly accumulates deposits, the purge air flow should be adjusted to alleviate this problem. 11.1 Replacement of the Shutter and the UV-Photocell on the D-LX 100 UL The UV-photocell has a limited lifespan. -
Page 26: (Fig. 15) Layout Of The Shutter Block With The Uv-Cell
Page 22 D-LX 100 The replacement of the Shutter block and the UV Cell is to be done in the following manner: 1. Disconnect the scanner cable. 2. Remove the cover (4 x M3) and the housing (4 x M5 – Allen screws). -
