ALVE ISLAND EXPANSION
9.1 G ENERAL INFORMATION
A configured Multipole or Fieldbus valve island is single step expandable up to a maximum of 4
additional valve stations. Confirm your valve island has not used any additional stations before
proceeding.
• In case of even number of stations, the valve island is expandable up to 4 additional valve
stations.
• In case of odd number of stations, the valve island is expandable up to 3 additional valve
stations because the last sub-base is a single additional station.
• The maximum number of valve stations is 16 (32 solenoids).
Note:
• When changing number of valve stations of a valve island, the part number on the label will
no longer correspond to the configuration. If you order the valve island based on the
Norgren part number, the original configuration will be delivered.
• If more than 4 additional valve stations are required to be added to the main PCB, the main
PCB must be changed.
• Fieldbus valve islands may have to be reconfigured after expansion. Please refer to the
specific information for each Fieldbus protocol in section 8 .
• For expansion of an AS-Interface valve island, please refer to section 8.6.5 and 8.6.7 .
• Please notice the position of blanking discs (multi pressure) before you expand a valve
island (see section 5.1.7 ).
• Fieldbus valve islands contain electronic devices, which could be damaged through
electrostatic discharge. Therefore electrostatic precautions must be taken. Specifically, the
person assembling or configuring the valve island must be connected to an earth ground.
To expand the VS18/VS26 valve island, expansion sets (A) are available. The set includes:
• 1 single station modular sub-base (C)
• 1 gasket (D)
• 2 socket screws
• 1 single station expansion PCB (E)
(Valves and accessories to be ordered separately.)
