The coloured indicator circle at the top right of the display is visible on all panels. It provides
a quick indication of the analyzer status. When it is green, the analyzer has no active faults
or warnings - all monitored parameters are within their specified ranges. When it is yellow,
this indicates that the Service relay is in the Warning state. When it is red, this indicates that
the Status indicator is in the Fault state, and so the analyzer will remain in back-purge mode
until the active fault(s) have cleared.
4.2.2 The Handheld Keypad
The handheld keypad is used to navigate between the various panels of the local display
user interface, perform a variety of control operations, and enter numerical data in user-
editable fields. It is shown in Figure 21.

The keypad must ONLY be connected to or disconnected from the analyzer when
the analyzer’s installation environment is known to be safe (non-explosive) .
The white keys on the keypad are used for numerical data entry, including a decimal point.
Not all the grey keys will be used for analyzer operation. The grey keys which do have a
function related to analyzer operation are described in Table 7.
