Automatic gas cabinet controller

There are a number of automatic monitors available that combine a number of the functions mentioned above into a single unit. These are sometimes connected to the panel s emergency shutoff valve or plant alarm systems, and will usually allow the operator to shut off the cabinet/panel by depressing an emergency shutoff button. For more extensive system control, the automatic gas cabinet controller, explained in the next section, should be used. 

During these various modes of control, the automatic gas cabinet controller should monitor the pressures in the panel providing an alarm and shutdown should the controller determine that one of the monitored parameters is not correct. The controller may be able to detect a leak, such as one caused by improper tightening of the CGA cylinder connection.
