Notes:
(Ref: Section 6
Reference and Specification) for details of other system components.
* High pressure gas exhaust - depending on pressure range.
** Optional vacuum system kit, allows the -ve port gas to be directly discharged to
atmosphere, by-passing the vacuum pump.
† 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 negative gauge pressure generator kit.

To protect the control module, for ranges of 70 bar and above 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.
