See Appendix D for a description of each message. The history log always keeps the most recent 128
messages of any type in memory. All three types of messages are also logged to the Micro SD card if
present.
Various screens are used in the CL1/CL2 to show some or all the messages (figure 5.2). Each of these
screens work in a similar manner.
Figure 5.2
The arrow next to the upper left soft key indicates to press that key to view the full log. When the soft key is
pressed a screen like figure 5.3 will be displayed. Pressing the <ESC> key will return to the previous menu or
screen.
Figure 5.3
From the screen shown in figure 5.3 the arrow keys below the screen allow scrolling of the messages in the
log. On some of the fault/event screens the <F4> key will acknowledge all the current fault/events.
NOTE: The history log does not allow messages to be cleared. The details for each screen in section 5.4 –
5.6 will describe which keys may be used.
Pressing the <ESC> key once will return to the screen in figure 5.2. Pressing the <ESC> key again from that
screen will return to the previous menu or screen.
