CARD EDGE PURGE FUNCTION SIGNALS

For the card edge connector, MFCs with normally open and normally closed valves
require inverse connections. Be sure to connect the signal properly. (To check whether
an MFC is normally closed or normally open, see "Model Numbers for this Manual"
on page 1-1.) Figure 4-5 shows the connections. Figure 4-6 and Figure 4-7 show the
internal circuitry for normally open and normally closed MFCs, respectively.
To disengage this function, disconnect the MFC terminal.
