Reaction Archive; Fault Archive - Hach BioTector B7000 User Manual

Reaction Archive

The Reaction Archive holds information on TIC, TOC, TC, VOC, COD, BOD, TN, 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
- Date
- Reaction Type - with the prefixes below:
S1 to S6:
M1 to M6:
√
x
CF:
RW:
RS:
ZC:
ZK:
ZM:
SC:
SK:
SM:
A1 to A6:
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.

Fault Archive

In the Fault Archive menu, the user can view the last 99 faults/warnings logged in the system, confirm if the
faults/warnings are current or not, and acknowledge current faults/warnings. If the archive is full, then every
new faults/warnings 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.
The faults/warnings 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 fault, 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 and information (e.g. "86_Power Up", "87_Service Time Reset" etc.)
-
displayed on the screen.
To acknowledge any current faults/warnings marked with an "*" in the archive, first identify and locate the
faults/warnings. See Section 9 Troubleshooting of System Faults and Warnings. Follow the necessary
troubleshooting procedures to solve the problem. 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.
