Conversion And Extension; Changing The Flow Direction (As2, As3, As5); Converting The Filter Pressure Regulator Valve (Fre) And Pressure Regulator Valve (Rgs And Rgp); Changing The Pressure Gauge And Housing Cover | Series As2, As3, As5 - Emerson AVENTICS AS1 Betriebsanleitung

7 Conversion and extension

Danger of injury if extension or conversion work is performed under pres-
sure or voltage!
Extension and conversion when under pressure or electrical voltage can lead to
injuries and damage to the product or system parts.
1. Make sure that the relevant system part is without pressure and voltage be-
fore extending or converting the product.
2. Protect the system against being restarted.

7.1 Changing the flow direction (AS2, AS3, AS5)

No conversion is necessary on the AS1 series. The "right/left flow" ver-
sion has a separate order number.
On delivery the flow direction is from left (1, IN) to right (2, OUT). The following
conversion on the product is necessary if the flow direction is to be changed:
7.1.1 Converting the filter pressure regulator valve (FRE) and pres-
sure regulator valve (RGS and RGP)
On all components, the flow direction change is performed by rotating an instal-
lation by 180° around the vertical axis. The housing cover and pressure gauge
need to be replaced for the purpose.
7.1.2 Changing the pressure gauge and housing cover | Series AS2,
AS3, AS5
See g Fig. 7
1. Remove the mounted pressure gauge by unscrewing it from the thread in a
counterclockwise direction.
2. Remove the blanking plug and screw it into the opposite side.
3. Remove the side cover caps on the compressed air connections by sliding a
suitable tool under the cover cap wings, carefully lifting them up and taking
them off.
4. Lift the front and rear cover cap by pushing the lock-in bolts (2 on each side)
up on the latches.
CAUTION! Remove the cover caps carefully and evenly so that the 4 lock-in
bolts do not break off.
5. Lift the front and rear caps evenly by carefully levering them open with a suit-
able tool and taking them off.
6. Mount the cover caps on the opposite sides in the reverse order.
The cover cap with the AVENTICS logo should be facing to the front.
7. Screw in the pressure gauge on the opposite side (see chapter g 5.2. Mount-
ing the pressure gauge)
8. Screw the blanking plug into the opposite side.

7.1.3 Rotating the reservoir (AS2, AS3, AS5)

1. Remove the reservoir.
2. Rotate reservoir 180° and click it back into place.
The release is now pointing to the front.
7.1.4 Pressure regulator valve conversion with continuous pressure
supply
No conversion is required for pressure regulator valves and precision
pressure regulator valves RGS-DS and RGP-DS with continuous pres-
sure supply. On these devices, air can be supplied from the left as well
as the right.

8 Cleaning and servicing

• Close all openings with suitable safety devices so that no cleaning agent can
enter into the system.
• Never use solvents or aggressive detergents!
• Do not use high-pressure cleaners for cleaning!
• Do not use compressed air for cleaning (blowing off) the maintenance unit or
equipment.
