Fault Status - Hach BioTector B7000 User Manual

Fault Status

O2 FLOW
RELAY PCB FAULT
OZONE PCB FAULT
CO2 ANALYZER FAULT
BIOTECTOR TEMPERATURE
COOLER TEMPERATURE
 This menu gives a short status history of several system devices
before a fault is registered. The default 0.0 values indicate that
there are no faults detected for the specific device.
 The O2 FLOW menu consists of 120 entries for the MFC
setpoint value (first column) and MFC flow value (second
column). The entries are sampled at every 1 second intervals. If
a fault is detected, the events are stored in the O2 FLOW fault
archive and are retained even if the fault is acknowledged in
Fault Archive menu. The archive is only over-written if a new
fault is detected.
 The RELAY PCB FAULT menu consists of 120 readings of the
input to terminal S41 FLT on the Signal PCB. If a fault is
detected, the number logged is "1". The events stored in the
RELAY PCB FAULT archive and are retained even if the fault is
accepted in Fault Archive menu. The archive is only over-written
if a new fault is detected. By careful analysis of the fault data, it
is possible to determine between an abrupt fault, and an
intermittent fault.
 The OZONE PCB FAULT menu consists of 120 readings of the
input to terminal S42 FLT O3 on the Signal PCB. If a fault is
detected, the number logged is "1". The events are stored in the
Ozone PCB FAULT archive and are retained even if the fault is
accepted in Fault Archive menu. The archive is only over-written
if a new fault is detected. By careful analysis of the fault data, it
is possible to determine between an abrupt fault, and an
intermittent fault.
 The CO2 ANALYZER FAULT menu consists of 120 readings of
the input to terminal S11, which is the 4-20mA signal from the
CO Analyzer on the Signal PCB. The entries are sampled at
2
every 2 second intervals, covering 240 seconds. If a fault is
detected, the events are stored in the CO2 ANALYZER FAULT
archive and are retained even if the fault is accepted in Fault
Archive menu. The archive is only over-written if a new fault is
detected.
 The BIOTECTOR TEMPERATURE menu consists of 120
readings of the BioTector temperature. The entries are sampled
at every 2 seconds intervals, covering 240 seconds. If a fault is
detected, the events are stored in the BIOTECTOR
TEMPERATURE fault archive and are retained even if the fault
is accepted in Fault Archive menu. The archive is only over-
written if a new fault is detected.
 The COOLER TEMPERATURE menu consists of 120 readings
of the cooler temperature. The entries are sampled at every 10
seconds intervals, covering 20 minutes. If a fault is detected, the
events are stored in the COOLER TEMPERATURE fault archive
and are retained even if the fault is accepted in the Fault Archive
menu. The archive is only over-written if a new fault is detected.
