2.2.2. Installation

The VTEST function block is automatically installed during the Valve Manager setup. If the Valve
Manager is to be installed on a different PC, the VTEST function block must be installed separately.

The Valve Manager Setup program offers an option to install the required VTEST function block library
component. Start the Valve Manager Setup program. Proceed through the installation normally, but
select the “Custom” option from the “Setup Type” dialog.
