SPECIAL FUNCTION SIGNAL DESCRIPTIONS
The following sections provide detailed signal information for signals that are
dedicated to specific functions.
Alarm Output (Error Detection) Signals
Not all MFC models provide these signals. To see if your model provides alarm output
signals see the specifications for the MFC model in question (see “Model
Specifications” on page 6-1). For signal descriptions, see Chapter 4, “I/O Connections
and Communication.”
FC-77X and FC-77XX MFCs provide error detection as a standard feature. The
function is an option on some other models.
For MFCs with the error detection feature, the MFC provides alarm output if it detects
a difference between the flow rate set point and the actual flow rate for longer than
eight seconds.
