Each selection on the main menu is detailed below
5.4.a Start Analysis (Figure 5.7)
Selecting this menu item will bring up the analysis screen below and start gas analysis.
Pressing <F1> during analysis will end analysis and return to the main menu.
Figure 5.7
The screen continuously displays the current gas concentration as long as the system remains in analysis mode.
When the concentration exceeds one or both of the alarm levels the text “Alarm 1” and “Alarm 2” will blink
appropriately. Anytime Alarm 1 is active the concentration display will also blink. When the concentration
passes the alarm levels the corresponding alarm output relay is triggered. The trigger will remain set depending on
the setting of Latching Relays – see section 5.4.c .
The bar graph on the right side of the display reflects the % of full scale for the current concentration reading. At
the lower left of the screen the display will show ‘P1’ or ‘P2’ if a pump is disabled either manually or
automatically. See section 5.4.d
During analysis the two keys on the right side of the display are active. When pressed the upper right key next to
the alarm levels will display a screen showing the current alarm messages. Analysis remains active while this
screen is displayed. If alarms are active they may be cleared by pressing <F4> (see alarm screen operation in
section 5.3.f). NOTE : If an alarm is cleared but gas is still present above the present alarm level the alarm will
immediately trigger once again. Pressing <ESC> will return to the analysis screen.
An asterisk next to the lower right soft key indicates that there are new warning/fault messages. Pressing the key
on the lower right next to the asterisk will display the messages while remaining in analysis mode. Any active
warning/fault messages may be cleared by pressing <F4> (see alarm screen operation in section 5.3.f). Pressing
<ESC> will return to the analysis screen.
