    They serve to avert dangers to life and limb of users and maintenance personnel and to prevent damage to property. General safety instructions The DURAG Compact Flame Monitor D−LX 200, D−LX 720 is in accordance with the current state of technology and the recognised technical safety regulations, hazards can nevertheless arise.

  • Page 18: Hazards Due To Electrical Equipment

    Cables must be routed so as to exclude the possibility of a risk of accident by persons stumbling over them or hanging from them. We recommend a power supply that guarantees reliable isolation between the primary and secondary circuits (e.g. the DURAG D-NG 24/05). CAUTION! Damage to electronic components due to electrostatic discharge (ESD) Electronic components are becoming increasingly small and complex.

  • Page 19: Hazard To The Device Due To Purge Air Failure

    2 Safety instructions  The Compact Flame Monitor is mounted directly at the boiler. In the case of systems with a low danger potential (ambient pressure, low temperatures, no health hazard), mounting/removal can occur during system operation. The applicable provisions and safety regulations for the system must be complied with and any necessary and appropriate protective measures taken.

  • Page 20: Qualified Personnel

    Qualified personnel The operating company's personnel who are responsible for safety must ensure that work on DURAG devices or systems is only carried out by qualified specialist personnel, whose competence has been verified by responsible experts.

    3 Explosion protection A process that generates a strong charge is a procedure by which charge quantities are generated per time that are high in comparison with the charge dissipation and hence can accumulate. Typical procedures are e.g. running drivebelts, pneumatic bulk material conveyor or multiphase liquid flows. Experience shows that exclusively manual procedures do not generate a strong charge.

Functional description The Compact Flame Monitor D−LX 200, D−LX 720 comprises an optical flame sensor and a control unit in one housing. The flame sensor converts the light signal from the flame into an electrical signal, while the control unit ensures self-monitoring, evaluates the flame signal and communicates the result.
  • Page 58 6 Layout and function Figure 6.3: Functional diagram In both microcontrollers for control and monitoring of the safety-relevant flame monitor functions and self-monitoring, both the static and the dynamic flame signals, depending on the set switching threshold (frequency, intensity), are evaluated for the Flame ON or Flame OFF signal.

    7 Installation, commissioning 7.6.1 Cable and screen The Compact Flame Monitor D−LX 200, D−LX 720 is designed for switching 24 V⎓ voltages via the operation readiness contact and the flame contact. The contacts can generate sparks when switching a load, which, in the case of long line lengths, can affect other switching circuits.
  • Page 81 7 Installation, commissioning recommended that the thermal insulator D-ZS 117 I (see page 45) is screwed on between the flame monitor and sighting tube and/or D-ZS 033-I swivel mount. It should however always be ensured that the Compact Flame Monitor does not exceed the maximum operating temperature of +85°C.

    8 Adjusting the flame monitor both switches must always (simultaneously, within 8s) be switched and moved to the same position. The D−LX 200, D−LX 720 has thresholds for the intensity (Intens.) and flame flicker frequency (Freq.). The thresholds are operated by means of rotary switches.

  • Page 89: Adjusting The Thresholds

    8 Adjusting the flame monitor Adjusting the thresholds Along with the usual threshold for flame intensity (Figure 8.3) D−LX 200, D−LX 720 also has the possibility of using the different flicker frequencies for the flame and background light (Figure 8.4) for deciding between flame OFF and flame ON.

  • Page 91: Setting The Amplification Characteristics Curve

    8 Adjusting the flame monitor Figure 8.4: Setting the flicker frequency [Hz] of the flame With the threshold of the flicker frequency, switch position 0 (zero) means a deactivation of the threshold. The detection of periodic signals is deactivated. With a switch position > 0 (zero) a threshold is established. The measured flicker frequency of a flame must exceed this threshold in order for a flame ON signal to be given (see Figure 8.4).

    9 Maintenance CAUTION! Damage to electronic components due to electrostatic discharge (ESD) Electronic components are becoming increasingly small and complex. Their susceptibility to damage from electrostatic discharge is increased accordingly. To protect these components, measures must be undertaken to prevent electrostatic discharge for all work performed at the open device (ESD protection).
