Additionally, at the bottom of the Home panel there are three status indicators / toggles whose functions
are described in Table 4.
Table 4: Home Panel Status Indicators / Toggles
Indicator
Function
Direct Board Control
Will indicate either (On) or (Off). If set to (Off), the analyzer’s inputs and outputs
are under control of the analyzer control board. If set to (On), the analyzer’s
inputs and outputs can be controlled manually to test functionality during
commissioning / maintenance. If set to (On), the analyzer cannot function
normally as it is unable to automatically control inputs / outputs in this state. To
toggle on or off, use the FIELD NEXT / FIELD PREV buttons to select, then press
ENTER to toggle.
Bypass
Will indicate either (On) or (Off). If set to (On), the analyzer’s analog output(s)
will output the fail-safe value (default 3mA) and the analyzer’s alarm / fault
relays will not be triggered in the case of an alarm / fault condition. This mode is
typically only set to (On) during analyzer maintenance. Bypass mode can be set
to automatically time out after a specified time interval of no input into the
analyzer keypad. The time interval can be set via the AccuLase-GPA™ web GUI.
To toggle on or off, use the FIELD NEXT / FIELD PREV buttons to select, then press
ENTER to toggle.
Save Log to USB
Stick
This function is only available if there is a USB thumb drive connected to one of
the USB ports on the AccuLase-GPA™ control board – if there is no thumb drive
connected, this function will be greyed out as shown in Figure 17. If a thumb
drive is connected, navigating to this function with the FIELD NEXT or FIELD PREV
buttons and pressing ENTER when the function is highlighted will cause the
analyzer’s archive log data to be copied to the attached USB thumb drive.
3.5 Alarms Panel
The Alarms panel indicates all currently system alarms, which can be hardware faults or stream related
(i.e. concentration) alarms. It is shown in Figure 18. When there are no alarms active, this screen will be
blank. Additionally, the bell icon to the left of the word ‘Alarms’ in the tab on the left side of the screen
will be green. However, if there are any alarms active, either hardware faults or stream-related alarms,
the bell icon be replaced with a yellow exclamation point icon ( ); this icon will also appear in the top
right corner of the analyzer display and will be visible on all panels. The alarm LED above the display will
also be illuminated. The description of all currently active alarms will be shown on this panel. Additionally,
alarms can be configured to be ‘latchable’. If an alarm is set to be latchable, it will continue to be displayed
on this page, and the hardware actions associated with that alarms (such as a relay or a solenoid) will
remain active until the alarm is manually acknowledged from this page. To manually acknowledge alarms,
use the FIELD NEXT / FIELD PREV button to select the Acknowledge Alarms button at the bottom of the
page, then press ENTER. All currently latched alarms will then be unlatched and cleared. If an alarm is not
configured to be latchable, it will automatically clear from this page, and the associated hardware actions
disabled, when the condition that caused the alarm to be triggered is cleared.
