Ɣ The operational log memory card is
demounted while power is supplied to
the oil concentration detector.
Ɣ The operational log memory card is not
mounted correctly.
Ɣ Turn off power to the oil concentration detector, mount
the memory card correctly, and turn on the oil
concentration detector again.

Ɣ Sensor unit transmission error.
Ɣ 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.

Ɣ Failure in the display PC board or the
operational log memory card.
Ɣ 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.

Ɣ The operational log memory card has no
free space.
Ɣ 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.

Ɣ The detection tube is not clean.
Ɣ The water supplied at fresh water inlet is not
clean.
Ɣ Execute manual washing (see”8-2-1”) and clean the
sensor (with brush (see “8-4”)).
Ɣ 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.
