2. Ensure gasket (D) is fitted before you mount the additional single station modular sub-base
(C). Then bolt the single station modular sub-base (C) together with the existing modular
sub-base. Tighten mounting screws (two per modular sub-base) with the specified torque. If
you are using a power screwdriver consider the maximum speed allowed.
3. Insert carefully the expansion PCB (E) in the same groove of the modular sub-base as the
main PCB. (The exception to this rule is AS-Interface. Please refer to section 8.1.4 .) Check
to make sure the plug-in connection on the PCB is centred with the orifice for the valve
interface.
4. Repeat steps 2 and 3 if you expand the valve island with more than one station.
5. Ensure end plate gasket is fitted before you remount the right end plate (B) to the modular
sub-base. Tighten mounting screws (two per end plate) with the specified torque. If you are
using a power screwdriver consider the maximum speed allowed.
6. Ensure valve body gasket is fitted on the bottom of the additional valve (F). Place additional
valve (F) onto the modular sub-base (C) aligned to the interface. Use plug-in connection as
positioning point.
