In the case "Warning" or "Error" is displayed on the LCD display screen
Symptom (LCD display)
When the oil concentration detector cannot be recovered by the above operations, call your local Fellow Kogyo distributor or Sales Division of
Fellow Kogyo.
In the case the other data is displayed on the LCD display screen
Symptom (LCD display)
Possible cause
The operational log memory card is
demounted while power is supplied to
the oil concentration detector.
The operational log memory card is not
mounted correctly.
Sensor unit transmission error.
Failure in the display PC board or the
operational log memory card.
The operational log memory card has no
free space.
The connectors of the sensor unit are
disconnected.
The connectors of the sensor unit are
disconnected.
Possible cause
The detection tube is not clean.
The water supplied at fresh water inlet is not
clean.
When the zero-point compensation is
omitted.
When an oil concentration of 5 ppm or more
is detected in the zero-point compensation
process (due to the influence by oil or
contaminant left in the detection tube)
When the zero-point compensation is
omitted.
When an oil concentration over 5 ppm is
detected in the zero-point compensation
process (due to the influence by oil or
contaminant left in the detection tube)
Action / measures
Turn off power to the oil concentration detector, mount
the memory card correctly, and turn on the oil
concentration detector again.
Turn off power to the oil concentration detector, mount
the memory card correctly, and turn on the oil
concentration detector again.
Turn off power to the oil concentration detector and
check the connection of Connector 1 (see "2-3 Internal
layout figure and terminal base"). If the error still
occurs, turn off power to the oil concentration detector
and replace the sensor unit.
Turn off power to the oil concentration detector, mount
the operational log memory card correctly, and turn on
power to the oil concentration detector again. If the
error still occurs, replace the operational log memory
card by a new one.
Replace the operational log memory card by a new
card. When the operational log memory cards must
be replaced so often since measurement is repeated
so frequently or power is turned on and off so
frequently, check the bilge pump pressure source and
the power supply source.
Confirm the connection of Connector 2 according to
"2-3 Internal layout figure and terminal base."
Confirm the connection of Connector 1 according to
"2-3 Internal layout figure and terminal base."
Action / measures
Execute manual washing (see"8-2-1") and clean the
sensor (with brush (see "8-4")).
Perform the zero-point check (see"8-1-2") and check
whether the oil concentration detector can run
normally. Inspect the fresh water supplied at fresh
water inlet when the oil concentration detector can
run normally.
Execute manual washing (see"8-2-1") and clean the
sensor(with brush (see "8-4")).
Execute manual washing (see"8-2-1") and clean the
