Data Retrieval - Turner Designs TD-107 5.0 Operation Manual

5.0
TD-107 Oil Content Monitor
Operation Manual
are set to Greenwich Mean Time (GMT) and
cannot be changed.
The following alarms and indications are
possible logged events within the
Datalogger:
•
POWER ON: Indicates that the power
has been turned on.
•
FLOW: Indicates whether the bilge
water is flowing to the monitor. Unless a
meter or external sensor input is
supplied, the flow input signal is derived
from auxiliary contacts on the separator
pump. Closed contacts on the pump
contact or provide the input signal to the
OCM flow contacts TB1 & 2 on the OCM
relay board.
•
SEPARATOR: Indicates whether the
separator is operating. This signal is
derived from the pump contactor
however the input to the separator
signal on the datalogger may be derived
from auxiliary contacts on the OWS
main power contactor. Closed contacts
indicate separator on.
•
HIGH (5 ppm) SIGNAL ALARM:
Indicates that the oil content is 5.0 ppm
or higher.
•
EARLY WARNING: Indicates that the
oil content is higher than the set point
stored in the instrument.
•
ZERO SIGNAL ALARM: Indicates that
the oil content reads 0.0 ppm. This
signal is logged for information purposes
and has no effect on OCM operation.
•
CELL CONDITION: Indicates the
sample cell has reached oil detection
limit of 10% and the cell could require
cleaning.
•
MAINTENANCE MODE: Indicates that
the monitor is being maintained (or that
the inlet valve is closed). Note that all
alarm relays are in alarm state while in
Maintenance Mode.
•
INSTRUMENT ALARM: A datalogger
event that can be caused by one of the
following alarms: LED Failure, Cell
Condition, or High Water Temperature.

8.2 Data Retrieval

Perform the following steps to retrieve data
from the Datalogger:
1. Close the inlet valve. This will log a
MAINTENANCE MODE event.
2. Open the enclosure door and insert a
USB data key into the USB data
port."EVENTS DOWNLOAD" will flash
on the LCD to indicate that the
"EVENTS.txt" file is being written to the
USB key. A row of '' will appear
across the bottom of the LCD as the file
writing progresses. This process may
take some time if the file to be written is
large.
3. "ALLDATA DOWNLOAD" will flash on
the LCD to indicate that the
"ALLDATA.txt" file is being written to the
USB key. A row of '' will appear
across the bottom of the LCD as the file
writing progresses. This process may
take longer than Step 4 due to the larger
file size.
4. When the LED is not illuminated the
USB key can be safely removed.
5. Shut and secure the enclosure door
after retrieving data.
The data files are text files that can be
imported into a computer. The EVENTS.txt
file only writes when there is a change of
alarm states. It includes the time and date
upon which alarm event occurred in addition
to the concentration measurement at that
time. The ALLDATA.txt file writes every 10
seconds with all alarm events and
concentration measurements.
Failure to shut the enclosure door
properly can result in corrosion of
the internal electronics.
