Signal	Return	Name	Signal	Description
Pin	Pin		Type
22	9	OVERTEMP	Digital	When an internal
			output	overtemperature shutdown
				condition is detected, a low
				(opto-coupler output) impedance
				is created between this pin and
				pin 9 (6 mA max).
				See Wiring Diagram 4-9.
				Note: This pin only detects a
				overtemp shutdown
				condition. The warning
				indication described in the
				Overtemp LED section is
				not reported on this pin.
23	10	INTERLOCK LOOP		See Pin 10.
		RETURN
24	11	DC BUS OK	Digital	When the interlocks are satisfied
			output	and the AC input voltage is
				within its specification, a low
				(opto-coupler output) impedance
				is created between this pin and
				pin 11 (6mA max).
				See Wiring Diagram 4-10.
25		CEX LOCK	Digital	See pin 12
