Functional description

The intended use of the Controller FS4 is the control of up to 4 pneumatic valves. These can be individually configured or used for up to 2 automatic changeovers between 2 gas sources each.

The control unit is designed to allow 3 different programs to be selected by the user:

The first program is intended for 2 independent gas supply systems, each of which has 2 gas sources, which switch automatically when one side is empty. This ensures uninterrupted gas supply. This can be carried out using valves located before or after the pressure regulating unit.

The second program is intended for 1 independent supply system which has 2 gas sources that switch over automatically when one side is empty. This ensures uninterrupted gas supply. This can be carried out using valves located before or after the pressure regulating unit. In addition, 2 valves can be controlled for an emergency or source shutdown.

The third program is intended for 4 valves for emergency or source shutdown. When valves are configured as independents, they can be enabled/disabled from the configuration screen.

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.
