Syntax

If ($BATT.eq.DEAD) then...

Use

This status indicator compares the value of the $BATT resident point to determine if the backup battery is discharged. This comparison is true if the battery is discharged.

Example

600  IF ($BATT.EQ.DEAD) THEN ALARM(P26BAT)

An alternate method to test the battery strength is to use the numeric value (0) of DEAD.

600  IF ($BATT.EQ.0) THEN ALARM(P26BAT)

Notes

This function can only be used in automation stations that have the ability to monitor the strength of their backup battery.
