Page 5: Preliminary Information
Preliminary information The ProGas 4 Gas Detector is a device designed as a component of the Gas Safety System and is intended for operation under heavy duty industrial conditions with broad variations of environmental factors (high temperatures, corrosive gases or vapours, moisture and dust). -
Page 6: The Principle Of Operation
www.atestgaz.pl The principle of operation The gas detectors measures the concentration of a given component, and then turns it – depending on the variety (described below) – to understandable signal for other devices of the gas safety system. In addition to the implementation of the measurement, the detector analyses the value of the measured concentration and may provide information about exceeding the following threshold values: warning 1,... -

www.atestgaz.pl Figure 2: Calibration of a gas detector with the FL.C head Safety Testing of the detector with a gas of unknown composition or excessive concentration is forbidden since it may lead to irreversible damage of the gas sensor. All activities related to connecting detectors, signallers and other system components must be carried out while control unit's power supply is off. -
Page 9: Conditions Of The Working Environment
www.atestgaz.pl Despite the power supply voltage for the Gas Safety System is off, dangerous voltage may persist across terminals of the Control Unit. Such a voltage may come from another system controlled by the same unit, for instance ventilation, that use one output pin of the control unit. -

Page 16: Figure 9: Correct Mounting Of The Gas Detector
www.atestgaz.pl Figure 9: Correct mounting of the gas detector The manufacturer recommends application of the Mounting Bracket WM8 (see Table 13) – since it enables easy calibration of gas detectors and protects their housings against damage. First the mounting bracket should be mounted to a support structure (wall) by means of two rawlplugs or M6 bolts. - Page 17 www.atestgaz.pl Should the cable gland design allows, connect cable shields to the gland to avoid threading the cable braiding into the device housing. Do never connect cable shields to the earthing potential (ground) of electronic boards. Cable shields must be insulated and slightly protrude from the cable gland inside the device interior. Do never connect shields to any terminal of the electronic device.
