	Name	Description		Values			Meaning

	AA	Alarm relay configuration
	id	Identity	rELy			Relay output
	Func	Function	nonE			No function
			dIG			Digital output
	SEnS	Digital output sense	nor			Normal (output energises when
						TRUE, e.g. program events)
			inv			Inverted (output de-energises
						when TRUE, e.g. alarms)

The following digital events appear after ‘SEnS’. Any one, or more, of the events can be combined on to the output (see Fig. 6-2) by selecting ‘YES’ in the lower readout.

1 - - -	Alarm 1 active	YES / no	(- - -)= alarm type (e.g. FSL).
2 - - -	Alarm 2 active	YES / no	If an alarm has not been
			configured

3 - - -	Alarm 3 active	YES / no	in ‘AL ConF’ list, then display
			will

4 - - -	Alarm 4 active	YES / no	differ:- e.g. Alarm 1 = ‘AL 1’.
