Room air quality is understood as subjective air quality, felt by human beings with their olfactory organs. As perception varies from person to person and therefore, air quality is assessed differently, a general definition of criteria for room air quality is not possible. By linearising and high operating temperatures, the air quality sensor achieves marginal drift and good stability. The sensor is automatically self-calibrating. The air quality sensor does not trace the concentrations of individual gases, but assesses the mixed gas as such, i.e. gas concentrations are not measured selectively. Therefore, it is not possible to specify gas concentrations by the unit ppm. Detectable gases: mixed gas, vapours of alcanoles, cigarette smoke, automobile exhaust gases, exhaled breathing air, combustion smoke (from wood, paper, plastics). In addition, compounds of alkanes, alkenes, aromats, terpenes, halogenated hydrocarbons, esters, aldehydes and ketones as well as native VOCs such as terpenes and isoprene are ranking among volatile organic compounds VOC. VOCs also evaporate from chemical products used in construction such as coating compounds, adhesives, or sealing compounds, furnishing objects, cleaning and care products, office chemicals and floor carpeting. The sensor's service life is depending on the type of burden and gas concentration and is more than 60 months under normal load conditions. The new design implies the alternative to choose between three sensibility ranges by means of DIP switches, comparable to three measuring ranges: LOW for low, MEDIUM (default, equivalent to the hitherto existing type of this device) for medium, and HIGH for high noxious gas contaminations.

KLQ AERASGARD ® RLQ - UP Room air quality sensor (VOC) with active output, in-wall, panel switch programme The room air quality sensor AERASGARD ® RLQ-UP is used to determine the air quality and qualitative estimation of room air pollution by diverse gas fractions (e.g. cigarette smoke, exhaled breathing air, solvent vapours, etc.). Energy conservation is achieved by ventilation of rooms on an as-needed basis. This in-wall version was developed for users with highest demands in respect of design, as these sensors are available in line with all current panel switch programmes, e.g. Busch - Jaeger, Berker, Feller, Gira, Legrand, Merten, Niko and Jung. The sensor's service life is depending on the type of burden and gas concentration and is more than 60 months under normal load conditions.

Pushbutton manual calibration air quality Features min. max. (RLQ-UP-S) Relay switching threshold Normally open contact Automatic Manual Notes Notes regarding RLQ - This device may only be used in non-precipitating air without above-atmospheric or below-atmospheric pressure at the sensor element. - In the operating mode with current output, the device delivers an output current of either 0...20 mA or 4...20 mA (selectable via jumper). This device is not a transmitter. - The voltage output is short-circuit proof. - Applying overvoltage will destroy the device. - In case of pollution, we recommend cleaning and recalibration in the factory. - The air quality signal “good“...“bad“ is represented by the output signal 0...10 V. - The device operating range covers 10...95 % relative humidity respectively 0...50 °C. Beyond that range, mismeasurements or increased deviations will occur. - The chemical sensor is a consumable. The lifetime of the sensor depends on nature and concentration of the pollutant gas burden. - If this device is operated beyond the specified range, all warranty claims are forfeited. Air quality is measured through a VOC sensor (metal oxide). Due to its functional principle, the lifetime of the sensor depends on nature and concentration of the pollutant gas burden. The sensitive layer of the sensor element reacts with all volatile organic compounds and is thereby modified in its electrical properties or “exhausted“. This process results in a displacement of the characteristic curve. Such characteristic curve displacement however amounts to less than 15 % ⁄ year under normal burden. In measuring air quality, the general condition of air quality is detected. Whether air quality is “good“ or “bad“ is differently interpreted by each person. Different pollution burdens and concentrations influence the air quality signal (0...10 Volt) in different ways. Examples for this are cigarette smoke, deodorant sprays, cleaning agents, or also various adhesive materials for floor and wall coverings as well as dyestuffs. Increased burdens e.g. by solvents, nicotine, hydrocarbons, aerosol propellants etc. intensify consumption ⁄ aging of the sensor element. Particularly under high pollutant gas burdens – also during non-operational idle state periods of the devices (transport and storage) – zero-point drift will occur. Consequently, this must be corrected at site according to the respective circumstances or basic burdens. Enclosure Frija To open the enclosure, set a screwdriver (2.0) in the groove at centre, press down, and lift up the bottom frame slightly. Pull top cover forward and hold it. Air quality measuring instruments of different manufacturers cannot directly be compared because of different functional principles, preset basic burdens (zero-point), and permitted burdens (amplification ⁄ sensitivity). Devices are preset respectively calibrated a ccording to the sensor manufacturer‘s specifications. Here, a zero-point and a final value is determined and thus a maximum burden. In particular cases, exceeding measuring ranges or excessive basic burdens on the devices will occur (outgassing floor carpeting, wall paint, etc.). In order to enable distinguishing different air qualities, devices need to be adjusted by the customer according to the c onditions existing on site that do not correlate to the factory-preset definition range and calibration. Please note that factory calibration is thereby lost and compliance with technical data can no longer be guaranteed. Automatic calibration of air quality (default), except for UP The minimum initial value for air quality is memorized within a period of ca. 4 weeks. After that period has lapsed, the output signal is standardised to zero-point (1.0 V). The maximum amount of correction is thereby limited to 1 V ⁄ interval. In this way, long-term drifts and operational aging effects of the sensor element are completely eliminated. Manual calibration of air quality, except for UP Manual calibration can be started independently from the position of jumper J3 by pushing the button. After connecting the device, a period of at least 2 hours of continuous operation of the device at „normal“ air quality is to be ensured. Manual calibration of the output signal to 1 V (zero-point) is started be pressing the button „Manual calibration“ (for ca. 5 seconds). Preparing for calibration is indicated by a blinking LED. Setting the output to 1 V at actual ambient conditions follows automatically thereafter. During this phase, the LED is permanently activated. After calibration is completed, the LED is deactivated. Putting in operation Upon energizing the device, a self-test and tempering takes place. Depending on ambient conditions, this process takes 3 to 5 minutes. During that time, the output analog voltage deviates from the actual measured value.

For operating voltage reverse polarity protection, a one-way rectifier or r everse polarity protection diode is integrated in this device variant. This internal one-way rectifier also allows operating 0 -10 V devices on AC supply voltage. Individual operation Connection scheme The output signal is to be tapped by a measuring instrument. Output voltage is measured here against zero potential (0 V) of the input voltage! When several devices are supplied by one 24 V AC voltage supply, it is to be ensured that all ”positive“ operating voltage input terminals (+) of the field devices are connected with each other and all ”negative“ operating voltage input terminals (–) (= reference potential) are connected together (in-phase connection of field devices). All outputs of field devices must be referenced to the same potential! Power supply AC 24V~ 0V DC 15-36V = GND Circuitry 0...10V When this device is operated on DC supply voltage, the operating voltage input UB+ is to be used for 15...36 V DC supply and UB– or GND for ground wire! V 0V/GND Supply voltage: Parallel operation Connection scheme In case of reversed polarity at one field device, a supply voltage short-circuit would be caused by that device. The consequential short-circuit current flowing through this field device may cause damage to it.
