Nitrogen Option On/ Off Control
Introduction
Nitrogen control is saved specific to a recipe. If operating the machine in Manual
Mode, clicking on the toggle button under “Nitrogen Control” turns On the
nitrogen. If the nitrogen was turned Off at the valve, refer to the following
procedure for turning it On. It is not necessary to manually turn Off the nitrogen
unless Lock Out / Tag Out is performed.
Procedure for Turning
Nitrogen On
• Manually open the On/Off inlet fully counterclockwise.
• Ensure that the Nitrogen is turned On in the software.
• Turn the pressure gauge clockwise until the pressure increases to 44 psi (3
bar). At this pressure the nitrogen flow rates can be read directly from the
flow meters.
• Adjust the controls above the flow meters until the desired flow rate is
achieved.
• Adjust the nitrogen at the flow meters until the desired flow rate is attained.
• Verify satisfactory ppm levels (<50 ppm).
