General information on operation
During regular operation, the system will be in supply mode. For information on general operation, refer to the operating manual for the pressure control panel.
If the outlet pressure is too high, the relief valve integrated on the pressure regulator opens. The outlet side of the relief valve is connected to the SP300 via a control line. If the pressure in the control line increases, the closing piston in the SP300 closes the supply line. All subsequent devices and fittings are no longer supplied with the medium used. In the triggered state, renewed pressurisation on the SP300 is prohibited!
The gas supply is only guaranteed again after the closing piston in the SP300 has been manually reset.
NOTICE

The pressure relief line cannot be discharged, as it is used to activate the safety shut-off device. Only the waste gas / exhaust air lines can be discharged.
The procedure and further instructions for installation, commissioning, operation and dismantling are described in the operating instructions of the pressure control panel.
