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.
‡ Optional vacuum system kit.

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.
Optional differential connection kit.
