Product Description

Dungs GW500A4 250V IP 54 221201 Gas Pressure 100-500 Mbar High Burner Control Compressor Switch Adjust Air

Product Description

 

Technical description

The GW…A4 pressure switch is an adjustable pressure switch as per EN 1854 (GW 6000 A4 as per DIN 3398T3) for burners. It is suitable for closing, opening or switching over a current circuit when the actual pressure value deviates from the specified pressure setpoint. The specified pressure setpoint (operating point) is set at a setting wheel using a scale.

 

Application

Pressure monitoring in burner control systems Suitable for gases of gas families 1,2,3 and other neutral gaseous media, as well as air, flue gases and combustion products. GW 500 A4: Free of non-ferrous metals, suitable for gases up to max. 0.1 % by vol. H2 S, dry.

 

Approvals

EU type test approval as per EC Gas Appliance Directive: GW…A4 CE-0085 AO 3220 EU type test approval as per EC Pressure Equipment Directive: GW…A4 CE0036 Approvals in other important gasconsuming countries.

 

Functional description

Single-acting pressure switch or pressure limiter in pressure range. The pressure switches and/or pressure limiters work without using any auxiliary power.

GW ...A4 pressure switch

The control unit responds to pressure. If the set reference value is exceeded or undershot, the circuit is switched on, off or over.

ÜB A4, NB A4 pressure limiters

The control unitresponds to pressure. Interlock is performed when the set reference value is exceeded or undershot.

The "Locked" switching state is indicated by a glow lamp. Restart is only possible by activating the reset
button on the setting wheel of the pressure limiter after the operating pressure is attained.

ÜB A4: Switches and locks when the set pressure is exceeded.

NB A4: Switches and locks when the set pressure is undershot.

Double pressure switch GW A4 / GW A4

CombinationoftwoGWA4singlepressure switches flanged together. The setting of the two reference values is performed separately and independently. This permits a combination of different reference value setting ranges. The same medium and pressure are applied to the two control units.
