1 Compact es for gas and air GW A6 Double GW A6 / GW A6 5.6 Printed in Germany Rösler Druck Edition Nr Technical description The GW A6 and the double GW A6 / GW A6 are adjustable compact es for firing systems. They are suited for ing a circuit on, off or over if the actual value changes compared to the setpoint. The setpoint (ing point) is set on an adjusting wheel with scale. A test nipple is integrated in the metal housing as standard. Application Pressure monitoring in combustion, ventilation and air-conditioning technologies. Suitable for gases of families,, and other neutral gaseous media. Approvals EU type test approval as per EU Gas Appliance Directive. TÜV (German Technical Inspectorate) test as ; special construction type as per TRD 604 and VdTÜV leaflet, Edition 00/, as well as Class S as per EN 854. GW...A6 CE-0085 AO 00 Approvals in other important gas-consuming countries.

2 Functional description Single-acting in over range. The es operate without any power supply. Switching response GW A6 Short response time during fluctuations. GW A6/ Slow response time during short-term fluctuations by additional damping nozzle. GW A6 The control unit responds to. If the setpoint (mbar) is exceeded or undershot, the circuit is ed on, off or over. GW A6 / GW A6 double Combination of two flanged GW A6 single es. The two setpoints (mbar) are set separately and independently. A combination of different setpoint ranges is therefore possible. The two control units are fed from the same medium at the medium s. GW A6 ing function If increases: NC opens, NO closes. If drops: NC closes, NO opens. COM p NO NC Definition of p ing difference The p ing difference is the difference between the upper and lower ing. Pressure at control unit p ing difference Setting tolerance Adjustment when drops upper ing rising falling lower ing 6
