5.9.1 General
The General box contains fields that affect the overall configuration of the analyzer.
• Live PPM Enable - If a checkmark is placed in this box, the analyzer’s LCD screen will
update the gas concentration as it is calculated within the analyzer on a live basis. When
this checkbox is left un-checked, the screen will only update with a new concentration value
when an analysis cycle has completed.
If Live PPM is enabled, the concentration units displayed on the LCD screen will have an L
in front of them – i.e. if the concentration units are PPM, then the screen will read LPPM if
Live PPM is enabled.
•
Live mV Enable -
If a checkmark is placed in this box, the analyzer’s LCD screen will show
the raw sensor output, counting down from approximately 1000mV, rather than the sensor
output that is adjusted to count up from 0mV. If the Live mV is enabled, the units of the
sensor output displayed on the unit’s LCD screen will change from mV to LmV.
• Backlight Lock On - The LCD on the analyzer has a backlight that causes the screen to
light up and be easier to read. If this checkbox is checked, the backlight on the screen will
be continuously turned on. This should only be checked if power consumption on the
analyzer is not a serious concern.
• Analysis Result Display Decimal Place (GUI Only) - This field allows the user to set the
number of decimal places from 0 – 4 in the analysis result. This is shown only on the
Analysis tab.
•
Site Identification - This box contains three fields that contain the unit’s unique
identification. The Serial Number field contains the analyzer’s serial number. The Tag field
tells the operator which site the analyzer is installed at, and the Location field tells the
operator where in the site the analyzer is installed. Do not change the Serial Number field
under any circumstances unless instructed to by Galvanic service personnel.
• Version - The values in the three unchangeable fields in this box show the current versions
of firmware installed in the analyzer, the sensor block, and the Rosetta that helps the GUI
identify the data it reads from the analyzer. These values are useful for diagnosing
problems.
• Bypass Timeout - Bypass mode disables any outputs that may be triggered by alarms and
is normally used when service is being performed to avoid inadvertent triggering of alarms,
for normal operation, it is essential that bypass mode be disabled.
The analyzer is equipped with a bypass timeout. When enabled, by putting a checkmark in
the Enable box, bypass mode will automatically be exited by the analyzer after a certain
number of seconds after the last keypad button push. The length of the bypass timeout, in
seconds, can be set by the user in the Bypass Timeout (s) field. By default, this is set to
450 seconds, and is disabled. When the analyzer is in bypass mode, the output from both
analog outputs goes to the fail-safe output to ensure that the user recognizes that the
analyzer is in bypass mode.
•
Furnace - This box is only relevant for systems that include the total sulfur accessory
(Section 2.9). The
Furnace Pulse Width
is the duty cycle of power that is delivered to the
total sulfur furnace, and serves as a temperature control mechanism for the furnace.
Generally, the duty cycle for a 110-volt system is 40% and 10% for a 230-volt system. If the
furnace is not present, the Furnace Pulse Width will be set to 0.
