APPENDIX 1 Alarm Information.
APPENDIX 1a Alarm, Warning and Fault Codes
The alarm, warning and fault codes shown on the display when the alarm pages are selected contain a alarm function code
as listed below together with the time and date that the alarm was set and reset (if that has occurred). In all the following
items N will indicate the Stream number 1, 2 or 3.
