2.2.5 Reaction Archive Screen
The Reaction Archive holds information on TIC, TOC, TC, VOC (in mgC/l), COD, BOD (in mgO/l), Drinking
Water parameters (REMOVAL in %, and RESULT in FAIL/PASS condition), stream valve, reaction range,
start time and related analysis information for the last 9999 reactions. If the archive is full, then every new
reaction overwrites the oldest one in the archive. As the Reaction Archive contains 9999 events, the user
must first enter the date at which the viewing of the archive starts. The Enter Date menu allows the user to
specify the date of the first displayed reaction from the archive.
Each reaction record in the reaction archive contains:
- Start Time - reaction start time, which is displayed without seconds in this menu
- Date - reaction date
- Reaction Type - with the prefixes below:
S1 to S3: Reactions from stream 1 to stream 3.
M1 to M3: Reactions from manual sample stream 1 to manual stream 3.
√ Sample sensor detected the sample or there is no significant quantity of air
bubbles in the stream/manual grab sample lines.
x Sample sensor detected no sample or there is significant quantity of air
bubbles in the stream/manual grab sample lines. See Sample Status in
section 8.3.8 Fault Setup for details.
RS: Remote standby reaction.
ZC: Zero calibration reaction.
ZK: Zero check reaction.
ZM: Manually input zero adjust.
SC: Span calibration reaction.
SK: Span check reaction.
SM: Manually input span adjust.
A1 to A3: 24 hours average result from stream 1 to stream 3.
The user can navigate through the displayed reactions individually by pressing the UP and DOWN keys each
time, or can navigate in steps of 10 reactions using the LEFT and RIGHT keys. Depending on system
analysis type (e.g. VOC, TC –TIC etc.) and system display options (e.g. COD and/or BOD) settings, BioTector
displays additional reaction data held on additional Reaction Archive screens. To access the screens, press
the ENTER key, and to return to the previous screen, press the ESCAPE key.
2.2.6 Fault Archive Menu
In the Fault Archive menu, the user can view the last 99 faults/warning/notification events logged in the
system, confirm if these events are current or not, and acknowledge the current events. If the archive is full,
then every new event overwrites the oldest one in the archive. The user can navigate through the displayed
reactions individually by pressing the UP and DOWN keys each time, or can navigate in steps of 10 reactions
using the LEFT and RIGHT keys. See Section 9 Troubleshooting of System Fault, Warning and
Notification Events for a list of all systems fault, warning and notification events.
The faults archive events are divided into three categories:
- Fault: Faults are categorized as events, which stop BioTector operation. The 4-20mA signals are set
to the fault level, and the fault relay is activated. The BioTector cannot be started unless the fault in
the archive has been acknowledged.
- Warning:
Warning is a minor event, which does not require the BioTector to stop. The 4-20mA
signals are not changed, only the fault relay is activated.
- Notification: A notification is an information (e.g. “86_Power Up”, “87_Service Time Reset” etc.)
displayed on the screen.
To acknowledge any current events marked with an “*” in the archive, first identify and locate the
faults/warnings/notification. Follow the necessary troubleshooting procedures to solve the problem. See
Section 9 Troubleshooting of System Fault, Warning and Notification Events for details.
Acknowledge the fault by pressing the ENTER key in the Fault Archive menu. Please note that there are
system faults (e.g. 05_Pressure Test Fail), which cannot be acknowledged by the user. Such faults are reset
and acknowledged automatically by the system when system is started, when system is rebooted or when the
fault condition is solved. If an event cannot be acknowledged when the system is running, a “SYSTEM
RUNNING” message is displayed on screen.
