VS18/VS26 MAINTENANCE & INSTRUCTION BOOKLET
8.1.4 AS-Interface assembly / Installation of PCBs
Tool:
VS18/VS26 Philips screwdriver size 1
1. Important: Make sure valves are not already mounted on the valve island, because the AS-
Interface PCB (B) as well as the expansion PCB (C) could become damaged during
assembly.
2. Insert the AS-Interface PCB (B) in the middle groove of the left end plate and the modular
sub-bases. Consider, that the single station expansion PCB (C), different from the main
PCB (B), has to be inserted in the left groove of the left end plate and the modular sub-
bases. Check to make sure the plug-in connection on the PCB is centred with the orifice to
the valve interface.
3. Plug the lowest connector of the Fieldbus E-connector-kit (A) into the connector on the AS-
Interface PCB (B).
4. Plug the other connector of the Fieldbus E-connector-kit (A) into the upper connector on the
AS-Interface PCB (B).
5. Ensure connector-kit gasket is fitted on the left end plate.
6. Mount the Fieldbus E-connector-kit (A) with two mounting screws on the left end plate.
Tighten the screws then with the specified torque. If you are using a power screwdriver
consider the maximum speed allowed.
7. Ensure gasket on the bottom of the LED window (D) is fitted and place the LED window on
the left end plate. Turn mounting screws by hand in the existing threads and tighten then by
hand.
