Layout and function 5.2 Functional diagram The measuring device D−R 800 operates according to the () forward scattering principle. The concentrated and modulated light of a laser diode penetrates the measuring volume. The light scattered by the dust particles is largely scattered forwards, therefore the receiving lens is positioned here.
Layout and function for converting scattered light into mg/m³ must be entered. However this does not affect the current outputs, limit values etc.. A pollution measurement is performed every 5 min in order to record dust deposits on the optical boundary surfaces and the ageing of the optical elements. 5.3 Supply unit 5.3.1 Layout of the supply unit The power supply for the measuring head contains...
Layout and function 5.3.2 Purge air heater (optional) The purpose of the (optional) purge air heater is to heat up the purge air to 40°C max. This option is required only if the local climatic conditions mean that the minimum temperature listed in the checklist in section 6.2.1 (from page 48) for the purge air supply may not be attained.

Configuration, installation, commissioning Is suitable purge air available? The fresh air drawn in by the supply □ unit for the purge air supply must be free of dust and oil, and have a temperature between -20 and +40°C. purge air heating (see page 43) should be provided if necessary.
Configuration, installation, commissioning Figure 6.2: Dimensionaldrawing (measuring )probe 6.2.2 Transport The laser in the probe is optically calibrated, therefore avoid impacts to the measuring probe. If due to rough treatment the measuring light beam does not reach the receiving unit coherently, the measuring result will be corrupted. Wherever possible, use the original packaging for transport: The moulded packing is designed to ensure safe transport.
Configuration, installation, commissioning The installation location should be as free of vibrations and oscillations as pos- sible. If this is not possible, the device should be installed so that it is insulated from any vibrating suction draught, so that the measuring system is not affected. Figure 6.3: Installation point of the probe;...
Configuration, installation, commissioning If there is not enough space available, the upstream section (A) should be longer than the downstream section (B) in the ratio 2:1. 6.3 Installation 6.3.1 Weldingin the flange The welding in of a welded-in flange is different in a vertical flue from a horizontal flue.
6.3.2 Connection Power supply, operating media Install the supply unit. All external connections of the DURAG Dust concentration meter are made via the supply unit. Power supply, data interface and purge air supply are located in this unit.
Configuration, installation, commissioning As the purge air is made available in the supply unit (2), the device casing must be sealed airtight. For this reason the casing door is sealed with a rubber bead and the unused cable ports are closed with plugs. (A) Intake ferrule for purge air (B) Purge air hose (C) Purge air restrictor (see Installation, purge air supply from page 58)

Configuration, installation, commissioning The two potential-free current outputs 1/2 and 3/4 are active and have an common earth potential. The current input 5/6 is active and is intended for direct connection to an optional temperature transmitter. The earth potential is at that of the supply. Installation, purge air supply The purpose of the purge air is to protect the module mounted on the dust duct.

Page 60
Configuration, installation, commissioning The two connections on the measuring probe must not be switched over. Otherwise the supply of purge air could not reach the measuring probe, and the transmitting/receiving unit would quickly be irreversibly damaged by overheating and dust. Never push the measuring probe into the dust duct without switching on the purge air supply! The purge air hose is designed for a maximum ambient temperature of...
Configuration, installation, commissioning 6.4 Commissioning 6.4.1 Measures before initial commissioning Are the preconditions for operation satisfied? Is the supplied dust measuring probe suitable for the existing duct in □ respect of its gas flow orientation (horizontal, vertical flow direction, see section Equipment on page 38)? For a system that has been correctly configured and installed the red dots on the probe flange and the welded-in flange should be alongside each other in the upper position.
Configuration, installation, commissioning 6.4.2 Commissioning First plug in the connection cable to the measuring probe, using the plug connector and secure it with the cap nut. The cap nut screwed connection is sealed with a rubber ring. The nut must be well tightened against the resistance of this rubber ring, to make sure of a reliable seal at the connection.
Configuration, installation, commissioning Each time it is switched on, the device performs a self-check and a reference measurement. During this process, "I24 Initial" appears on the display and flashes. Measurement is then started immediately, and the current dust concentration (A01) is shown on the display.

Operation 8.5 Set-up, adjustment Before the D−R 800 can output the correct dust value it must be set up and calibrated. 8.5.1 Calibration In principle, a gravimetric comparison measurement should be performed by a recognised test institute (accredited measuring body) to EN 13284 to calibrate the D−R 800.
Operation For a sufficient signal level it may be necessary to make the smaller (<25mg/m³), so that a larger part of the current output range is used. The following simple relationship applies: (example.. 2500 The current I is calculated from the scattered light S according to the following function f(S): ...
Operation This gives (to EN13284-2) Current Concentration mg/m³ 3.93 0.38 4.70 0.90 5.16 1.21 8.34 3.34 18.09 9.87 Table 8.2: Value pairs table for the calibration function These values are subjected to a variability check during calibration (permissible deviation of the gravimetric concentrations from those of the D−R 800 has not been done for this example).

The measuring lance then performs a reset and an auto-initialisation. Any measuring results not saved beforehand will be lost!

Maintenance Figure 9.3: Cleaning the optics on the measuring probe b) Using a 2.5 mm hex wrench, unscrew the four socket-head screws and remove the protective cap from the receiver end of the optics unit at the end of the lance. Pull off the protective cap, and use oil-free compressed air or a soft lint-free cloth, moistened with water and alcohol if necessary, to remove any deposits.

Maintenance 2. Push down the button (circled) on the temperature limiter miniature circuit- breaker that has tripped (Figure 9.6B) back into the retracted position (Figure 9.6A). The switch can be reset only once the instantaneous heater has cooled to temperature lower than the setting of the temperature limiter (Figure 9.6a). 3.
