2G. Thus this detector is suitable to be operated in hazardous areas with potentially explosive atmospheres of zone 1 and zone 2. The PQ series detector comprises a gas sensor type Ex- proof (protection type flameproof enclosure db type). PQ Series detector for flammable gases performs % 0 to % 100 LEL measurement range;... - Page 7 1. Very high gas concentrations The measuring method of PQ series detector based on heat produced by reaction on the oxidation of a flammable gas when pellistor sensor used. There is not enough oxygen in the sensor to perform oxidation process correctly in case of high gas concentrations. Hence the measuring signal decreases at high gas concentrations and even can lead to measuring signal within the measuring range again.

Page 15: Electrical Connections
Caution: All electrical connections should be made in accordance with any relevant local or national legislation, standards or codes of practice. Prosense detectors can operate between 12 - 24 VDC. The connection socket located on main board as given in Diagram-11 (page 19) and details given in below table 2:... - Page 16 Minimum power consumption of the detector without any optional module is 1W. The current required to drive the detector at the minimum voltage is (I = P / V) : 1.0 / 12 = 85mA (I detector). Maximum power consumption of the detector when optional relay modules installed and all relays are active is 4.0W.
