Replacing the operational log memory card
Replace the operational log memory card when the remaining free space of the operational log memory card becomes insufficient or when
viewing the content of the other (old) operational log memory card.
CAUTION
●
Turn off power to the oil concentration detector and make sure all lamps are off.
●
Do not try to replace the operational log memory card while power is supplied to the oil concentration detector.
If done, the memory card may lose its content or destroyed.
●
Do not touch the terminal contacts of the operational log memory card
.
●
The operational log memory card is very sensitive to static electricity and will be easily destroyed by it.
First remove static electricity from the oil concentration detector and your body.
■
Preparation
Prepare an operational log memory you want to use.
■
Removing the operational log memory card
Push the operational log memory card in the direction
①
The operational log memory card is unlocked and pops up a little.
Hold the operational log memory card at

■
Mounting the operational log memory card
Hold the operational log memory card with its notched portion faced to the rear and the gold-plated
contacts faced down and push in the operational log memory card in the direction
①
Push it until it hits the end, pushed back a little, and locked.
(Do not push in the card too strong. The card may not be locked.)
《
CAUTION
》
Please note one memory card should be used for only one
FOCAS-2000 unit.
If the memory card which was used in a certain FOCAS-2000 is inserted in another
FOCAS-2000 unit,

is pressed in this condition, the unit becomes Standby
condition. However density measurement cannot be performed.
All you can do is to confirm log.
For use, please check the instruction manual (replacing the operation recording memory
of FOCAS-2000) which is attached when you bought the memory card.
Notice: The vessels which navigate to US territorial waters, it should be retained
record for at least 3 years it may be needed.(accordance with 2.2.2.1 of 2013VGP)
●
Management and storage of the operational log memory card.
In some cases, the operational log memory card is required for inspection according to rules.
Put the replaced operational log memory card (replaced a maximum of 18 months ago) in a specified static-free storage bag,
write its date of replacement, and carefully store it for 18 months.
At the time of an on-the-spot inspection, the inspector may require the operational log memory card for viewing.

Replacing the fuses
The fuses may be blown out when the oil concentration detector screen shows nothing or the three-way valve connected to the oil concentration
detector is inactive although power is supplied to the oil concentration detector. Check whether the fuse is blown out.
●
The fuses works to protect the oil concentration detector and external units (three-way valve output signals) against overcurrent.
●
The oil concentration detector uses two types of fuses: fuse for the oil concentration detector and fuse for external unit.
Their ratings are different. Do not mix them up.
●
Use the specified fuses only.
●
When one of the fuses is blown out, the oil concentration detector or three-way valve output signal may be abnormal.
●
Do not use a flat-head screwdriver to turn the fuse holder cap.
CAUTION
●
Turn off power to the oil concentration detector and make sure all lamps of the oil concentration detector are off.
●
Replace the fuses by new ones. If the fuses are still blown out, the connections of the terminal base of the oil
concentration detector or the three-way valve may be defective. Inspect the insulation of the three-way valve
(for insulation defect due to aging) and terminal connections of the oil concentration detector.
■
Preparation
Prepare replacement fuses.
Fuse for oil concentration detector:
F
5 - 20 mm, ceramic tube type
3.15A, 250V (1 pc.)
Fuse for three-way valve
F
5 - 20 mm, glass tube type 2A, 250V (2 pcs.)
■
Demounting
1. Turn the fuse holder counterclockwise while pressing it with your finger.
2. Take up the fuse holder.
3. Pull out the fuse from the cap of the fuse holder.
■
Remounting
1. Insert the fuse into the cap of the fuse holder.
2. Turn the fuse holder clockwise with the fuse on the cap.
3. Check and make sure the fuse holder cap is tight.
