Figure 5-10 Aux Supply Low and External Control Fault LEDs

Aux Supply Low LED
LED turns red when the nominal
•
+24 VDC control voltage drops
below +19.5 VDC
External Control Fault LED
LED lights red: (a) when fault
•
occurs in internal I/O switch
power, or (b) when fault occurs
in the external control circuit
powered by +24 VDC supplied
via J4 pin 6
