Converting The Vtsa; Conversion To Ducted Pilot Exhaust And Venting Air - Festo VTSA Series Description

5. Maintenance and conversion
5.4 Converting the VTSA... valve terminal

5.4.1 Conversion to ducted pilot exhaust and venting air

5−18
The following conversion work can be done on the VTSA...
valve terminal:
Conversion of the valve terminal to internal or external
pilot air supply.
Conversion of the valve terminal to ducted pilot exhaust
Addition of pressure zones
Addition of vertical stacking components
Addition of valve positions (manifold sub−bases) or supply
blocks
By turning the valve seals, you can vent the pilot exhaust air
ducted via port 12 on the right end plate.
Note that the ducted exhausting of the pilot exhaust air via
connection 12 does not conform to the ISO standard. Under
certain circumstances, the VTSA... valve terminal can no
longer be operated with ISO valves from other manufacturers.
Proceed as follows:
1. Please observe the general safety measures in
section 5.1.
2. Use a screwdriver with a narrow blade to loosen the re
taining screws for all the valves. Remove the valves from
the manifold sub−bases (see Fig. 5/1).
3. Check the exhaust variant for which the VTSA... valve
terminal has been constructed.
