Notes: Refer to Section 6 Reference and Specification for details of other system components.
* High pressure gas exhaust - depending on pressure range.
† Optimum controller transient response and minimum time to set-point may be degraded if either
the pneumatic supply or vacuum system has restricted flow. Installing a reservoir volume, which
has larger capacity than the load volume, located in close proximity to the controller supply ports
can improve the controller response.

To protect the control module, for ranges above 100 bar, from over-pressure a suitable protection
device (such as a relief valve or bursting disc) must be fitted to limit the applied supply pressure to
below the MWP.
