6.12. Nitrogen Control Module
The Nitrogen Control module
(AZI P/N: Y990-0214) is an optional accessory
that is used in conjunction with the Nitrogen
Purge Kit to conserve nitrogen. The module
turns on nitrogen to the instrument prior to a test
and turns off the nitrogen after a test. This is
especially helpful when using a limited supply of
nitrogen (bottled nitrogen). The module also
monitors the nitrogen pressure and alerts the
user when the nitrogen source is depleted. The
incoming pressure must be between 4 and 20
psi inclusive.
The module connects to the USB Type A / Host port (marked USB) on the back panel.
• Unpack the module.
• Plug the Type A flat end of the included cable into the MAX
®
4000’s mating socket
(marked USB). If other USB devices are being used, a USB hub is needed to connect
multiple devices to the MAX
®
4000. (The hub must be self-powered, i.e. use an
external power adapter, or the Nitrogen Control module will not function correctly).
• Connect the Type B square end of the cable to the mating socket on the Nitrogen
Control module.
• The module is enabled through the SETUP menu (See section 8.4.6 Nitrogen
Control Module on page 76).
• When the module is connected, the module icon will appear in the bottom
left corner of the main screen, above the CONTRAST soft key.
The module’s flow connectors are connected into the nitrogen supply just after the
regulator in the standard nitrogen purge setup.
• Connect the input to the regulator, as shown.
• Connect the output to the Y-Connector, as shown.
