■1-1.Introduction
Thank you for selecting the 15-ppm bilge alarm (oil concentration detector) Model FOCAS-2000.
The bilge alarm (oil concentration detector) Model FOCAS-2000 has been developed based on market needs integrated with Fellow Kogyo’s
proprietary technologies.
This product meets the IMO resolution MEPC. 107(49).
Be sure to read this instruction manual. Store this manual always in a place of easy read.
IMPORTANTBe sure to read the following
The product is delivered with the precision and type approval certificates attached. Store them with caution.
Validity period of accuracy assurance is 5 years. MEPC.107(49) requires the manufacturer or a party approved by the manufacturer to verify the
accuracy of the product and take the IOPP certificate renewal examination within 5 years. (Replacement with a calibrated product is allowed.) Be
sure to request the agent or manufacturer for accuracy verification.Do not use the equipment for facilities relating to human safety. We will not
be responsible for any outcome resulted from such use.
1. Checking after shipment must be performed in accordance with the IMO regulations by a person having skills certified by Fellow Kogyo.
●Operating history is stored in the operation record memory in accordance with MEPC 107(49) Directives.
●It is a user's duty to store the record data for 18 months.
●Before the free space of the operational log memory becomes insufficient, this machine tells it on the LCD display.
When the free space of the operational log memory becomes insufficient, the machine may be disabled to run.
To run the machine, you must replace the operational log memory by a new one.
●The old operational log memory must be kept aside for at least 18 months from the date of replacement.
For more information, call your local Fellow Kogyo distributor or Sales Division of Fellow Kogyo.
2.
As this equipment is a certified one, no modification is allowed.
In addition, never break the equipment seal, as such an act is deemed as fraudulent.
3.
This equipment is warranted for one year after delivery. In case any failure responsible to Fellow Kogyo is experienced during the period,
the pertaining part or component shall promptly be replaced or repaired.
■1-2.Product Features

■1-3.Safety precautions
DANGER
●Shut off the power when undertaking construction of the equipment (installation, piping and wiring).
Fire, electric shock or injury may be caused due to a short circuit.
●Do not machine, disassemble or modify the product. An accident, fire, electric shock, electronic part mage or burnout may
be caused. If the product has been modified, we cannot take charge of repair.
WARNING
●Do not use the product when it is faulty. An accident such as electric shock and fire may be caused.
Stop the operation at once and repair the product.
●This machine is not provided with a power switch for the primary power supply.
Be sure to install a power switch at the power supply source.
●Do not leave the product in a subzero environment in the status where sample water or fresh water remains in the sample
water detection tube. The sample water detection tube will be broken by freezing, resulting in a failure.
●Never feed water contaminated with oil or impurities directly into the detection tube in the sensor unit. Since this machine
is a precision equipment, a malfunction or impossibility of measurement may be caused by contaminated detection tube.
●Please use the battery properly without making mistakes in terms of orientation of polarity.
Equipment might break down or be heated which leads to ignition.
CAUTION
●Never use the operational log memory card of this oil concentration detector (FOCAS-2000) for the existing oil
concentration detector (FOCAS-1800). If used, its data will be lost. We cannot assure and recover any operational log
data lost by the use in the existing oil concentration detector. By the way, FOCAS-2000 can read the operational log
memory card of FOCAS-1800.

Apply seal tape to the threaded part of the copper tube before coupling the tube to the port.
Restrictions on piping
ƕ䎃The length from the sample water outlet to the end of piping shall be 2 m or less and the fall shall be within 1.5m.
Be sure to provide hoppers.
ƕ䎃Piping length between Bilge Separator and Bilge Alarm shall be 3m or less. Bilge Alarm shall be set above the
Outlet height of Bilge Separator. Do not install Bilge Alarm lower than 2m below the top of Bilge Separator.
Operation pressure of Bilge Alarm is 0.03Mpa – 0.3Mpa. In consideration of recommended pressure for Bilge
Separator, adjust the operation pressure.䎃

䎃
䦟4-2. Outline of operating conditions
ƔThe FOCAS-2000 oil concentration detector automatically starts to operate when detecting a water pressure of 0.03 MPa or more at the
sample water inlet.
ƔAfter starting to run, the oil concentration detector waits for a preset time (warm-up time) until the sample water state becomes stable so as not
to detect a residue in the area between the sample water pipeline and the detection tube. In this state, the three-way valve output signal is off
and the bilge does not drain.
ƔThe oil concentration detector has two oil alarm points (Alarm1 and Alarm2). You can set an alarm point (in ppm) in the range of 5 to 15 ppm.
ƔThe Alarm1 oil alarm point is in synchronism with the three-way valve output signal. When the oil concentration is less than the specified oil
alarm point, the bilge drains. By the way, when the oil concentration exceeds the oil alarm point, the three-way valve output signal is output to
immediately stop drainage of the bilge independently of the setting of Alarm1 oil alarm delay.
ƔWhen the water pressure at the sample water inlet falls under 0.03 MPa, the oil concentration detector stops operation, feed fresh water into
the detection tube for a preset time period to keep it clean and leave no residue in the tube, and enters the standby state.
䦟4-3.䎃Preparing for Operation
ƔBe sure to set the clock right before using the oil concentration detector. If not, the oil concentration detector cannot run.
(When the clock is not set, an alarm is output. The alarm is reset, when the clock is set.)
ƔIf the oil concentration detector has any error, "Warning [xxx] or Error [xxx]" is displayed on the screen portion of the oil concentration detector
body.
ƔThe inside of the external pipe may be fouled with sediment. Be sure to flush clean the pipe inside before connecting the pipe to the oil
concentration detector.
1. Before turning on the oil concentration detector, be sure to check pipe joints and cable connection to the terminal base and make sure they
are firmly tightened.
2. When shipped out from the factory, the clock backup battery is insulated with an insulating sheet. Pull it out to enable the battery.
3. Check and make sure the clock backup battery and the operational log memory card are mounted firmly.
Pull out the
insulating sheet.
Make sure the clock
backup battery is mounted
correctly.
Make sure the operational log
memory is firmly mounted.
Make sure the connectors
are tightly fastened.
Esc Enter
Make sure the upper lid,
joint, filter, and drain are
fastened tight.
4. Turn on power to the oil concentration detector. Make sure the "POWER" lamp (green) lights.)

When it is judged the detection tube is not clean, "Warning: cell too dirty" is displayed on screen.
When this message is displayed, manually wash the detection tube (see “8-2-1”), shut off the primary power supply and clean the sensor

Since stain level of sample water detection tube is judged after manual operation is finished, this message disappears when the detection
tube is clean. If the message is still displayed, repeat the above steps. (clean the sensor (with brush, see”8-4”), manual operation using
mineral water (see “8-1-1”) and judging the stain level of sample water detection tube).
