3. Putting into Operation Use the patented screw joints of the curved tube on both sides of the cylinder rack to connect the gas cylinders. Tighten the screws with your hands. Please do not use any pliers, because the tightness will be achieved by the cylinder pressure. Close all the high-pressure cut-off intervalves and ventilation valves of the high-pressure manifold. Now you can open the cylinder valves to test if all the connections are tight. After that you can open the high-pressure intervalves. The pressure of the cylinder on the right and on the left is displayed on the...

5. Functional and Operational Principles Pneumatic Components The HEYER AEROTECH switch unit AGS 35 - 50 and AGS 35 – 50 SE is a device which is capable of switching between two cylinders by means of adjustable pressure limits. This process is carried out with the help of a switching valve which switches on the basis of a pressure difference in the medium pressure range. When operating the AGS 80 P with a liquid gas vaporizer, this unit always has priority (the supply takes place in the medium pressure range) and one cylinder side is always ready for operation. The device can also be...

General operation With normal conditions (no fault), the LEDs of Channels 1 / 2 / 4 / 5 (see Illustr. 2) will be green. When a press key is activated (excess or negative pressure) the LED will turn red or orange. At the same time, a permanent acoustic signal will be activated. As soon as the state of alarm has been cleared, the LED will turn green again. The buzzer will be deactivated. The acoustic alarm can be suppressed by means of the button. The LED will shine until the state of alarm has been cleared. Depending on the setting of the piston in the switching valve, the cylinder rack in...
