Functional description

The intended use of the Controller FP4 is the control of up to 4 pneumatic valves. These can be configured for an automatic purge process as well as for an additional valve as a cylinder valve, propellant gas valve or line shut-off valve.

The controller is designed to control an automatic purge process before and after a gas source change. The number of purge cycles and the duration of the individual steps can be individually set. In this case, the purge operation can optionally be monitored by a contact pressure gauge or a pressure-measuring sensor.

All controller actions which require an input from an operator are protected by a dual layer password system that allows up to five trained operators to have different operational access via their own personal Identification Number (PIN).

Configuration of the controller type, digital and analogue inputs and alarm settings are all set via the GUI.
