a: These submenus can be accessed from both Menus (Main and Extended); except the Service submenu,
they contain more parameters and commands in the Extended Menu.
b: There are four modes: Latch, Normal, Force ON and Force OFF.
The following Sections describe the parameters and commands of each submenu.

5.5.1 History Submenu

The History submenu allows the user to:
• Consult the four historic data files:
- Events (recording at the time of events; example: alarms).
- Short Term (recording at fixed logging rate; example: every 15 minutes).
- Long Term (recording at fixed logging rates; example: every 6 hours).
- Service (recording at the time of the semimonthly, automatic sensor test).
• Set the logging rate of these files.
• Clear the content of these files.
5.5.1.1 Events History
When an event occurs, the date and time of occurrence, an event message and ten
variables are stored in historic data file Events. Its capacity is 500 recordings; when the
file is full and a new recording occurs, the oldest recording is deleted (first in, first out
method). All event messages and their description are provided in Appendix E.
