1.0 Introduction and general description


The JOWA SEAGUARD 15ppm Bilge alarm is designed to monitor the effluent
from a bilge water separator. The alarm is approved to IMO MEPC 107(49).

There are 2 alarm out signals which are triggered by the ppm oil content of the
separators effluent.

The JOWA SEAGUARD has a cleaning function, auto flush, designed to keep
the sensor as clean as possible. Auto flush occurs automatically.

The JOWA SEAGUARD log is controlled by a signal from the separator and is
saved on a removable SD card.

Before leaving our workshop each unit has to pass a quality-test, where
all functions are tested and checked.

All components are of the highest quality. Spare parts are easily available from
one of our offices or representatives worldwide.

3.0 Installation



This chapter contains step-by-step information detailing how the JOWA
SEAGUARD is installed.

3.1 Delivery

The JOWA SEAGUARD is delivered as a complete unit mounted on a base
plate

The unit has passed a work-shop tested before delivery.

3.2

Placement of the skid


The JOWA SEAGUARD should be placed on a plane vertical surface and
bolted using the pre drilled holes in the base plate. When installing the unit it is
important to leave a minimum of 500mm working space in front of the unit (see
mechanical drawings chapter).

3.3 Pipe

Connections


All pipe connection points are G ¼” female threads (see mechanical drawings
chapter). Piping layout from the separator to the JOWA SEAGUARD should
follow the schematic shown in the flow diagram chapter.

3.4 Electric

Connections


The electrical equipment of the JOWA SEAGUARD is ready for installation
when delivered. The power supply should be single phase 230 VAC 50/60Hz.
Other power supplies on request. See the electrical drawings for further
information.

Connect the main cable to terminal J1 1,2 in the main control box.

3.5

Adjusting the back pressure / flow in the sensor


To adjust the back pressure/ flow in the sensor there is a small flow restrictor in
the sample outlet connection. The flow restrictor is only 11mm in Diameter/
4mm thick and the orifice is 1mm.
The flow restrictor is located behind the coupling that is mounted in the sample
outlet.
Standard delivery is 1mm, but if this is too small hole, it is very easy to drill a
bigger hole.
It is recommendable to drill only 1 millimetre each time and then test again to se
if the back pressure/ flow are ok.

When the Bilge alarm is delivered as a loose item, the flow restrictor is delivered
in a bag taped on to the bilge alarm.

This flow restrictor should always be mounted in the outlet hole before the
coupling is connected.

4.0 System Function Description.



This chapter provides a detailed description of the unique functions of the
JOWA SEAGUARD. It is intended that the information in this chapter may be
used to help the operator optimise the JOWA SEAGUARD performance to his
or her specific bilge requirements.

4.1 Basic Functions

The main task of the JOWA SEAGUARD is to monitor the oil content of the
effluent from a bilge water separator and alarm if the oil content exceeds
15ppm. The JOWA SEAGUARD also logs specific events from the separator
and the JOWA SEAGUARD. These logs are useful in connection with
inspections.


4.2 Alarms

There are 2 alarm out signals which are triggered by the ppm oil content of the
separators effluent or by internal error codes. The first alarm triggers when the
effluent goes over the alarm’s set point. If the ppm oil content of the separators
effluent remains over this set point for a defined period the second alarm is
triggered. The alarm set points and time delays are adjustable.

4.3 Logged

Data


The JOWA SEAGUARD log is controlled by a signal from the separator and is
saved on a removable SD card . NOTE! The SD card is sealed against
unauthorised removal. The log updates every minute if there is no new events
occurring within the minute. The following data is logged:

• Date/GMT

time

• Start/stop of the log
• Auto flush start/stop
• High ppm alarm
• Alarm reset (under 15ppm)

11

4.3.1 Format of the log names

The logs are named following the following routine:

YY-MM-DD-HH:TT:SS

YY = year e.g. 06 for 2006
MM = month, 01-12
DD = day, 01-31
HH= hour, 00-24
TT= min, 00-60
SS= sec,00-60

4.3.2 Format of the logged data

PPM = actual PPM value at recorded time.
Lim = the ppm set point for alarm.
Sep = status for separator. (0 = inactive, 1 = active)
Val = position for 3-way valve.(0 = sample, 1 = clean water)
Al1 = condition for ALARM1

(0 = inactive, 1 = active)

Al2 = condition for Alarm2

(0 = inactive, 1 = active)

Sim = simulation mode ( 0 = inactive, 1 = active)
Err = Error code. (00 = no errors)


4.3.3 Auto

flush


Auto flush function cleans the sensor. During auto flush both alarms are
activated.

Auto flush occurs according to the following steps:


0

Both alarms are triggered at the same time.

1

2 seconds pause

2

Valve changes to clean water

3

Flushing for 20 seconds (adjustable)

4

Re-zero of the sensor (takes 13 sec)

5

Valve changes to sample water

6

2 seconds pause

7

Alarms released, ready


NOTE:
When auto flush is enabled, an auto flush procedure is performed when the
separator is started and when it is stopped. If the re-zero action fails at start up,
a second flush procedure is performed.

5.3.5 Simulation.

According to MEPC 107(49) § 4.2.5, onboard testing according to the
manufacturers instructions shall be permitted.

To facilitate this the JOWA 15ppm bilge alarm has a service menu called
simulation. A simulation run permits the user to imitate a ppm over the alarm set
point, (max alarm set point 15ppm).

This simulation run works by simulating the ppm ramping up from the real ppm
to a peak of 20ppm and down to the real ppm again.

-In this case “real ppm” refers to the ppm which is actually present.

Each ppm step in the simulation run takes 2 seconds. If, for example, the real
ppm is 10ppm when the simulation is started the alarm counts up from 10ppm
to 20ppm. If at the end of this simulation the real ppm is now 8ppm the count
down stops here


NOTE!
-If the real ppm value is higher than 15ppm then it is not possible to start a
simulation run
-During simulation the alarm continually monitors the real ppm in the
background. If at any time during a simulation run the real ppm goes higher
than 15ppm, there will be an alarm.
-All simulation runs are logged if the Sep in signal is active.

6.0 Maintenance

The JOWA SEAGUARD requires very little maintenance.

Weekly maintenance:

- Clean the sensor with the provided brush.

- Do an manual auto flush after the sensor is clean.
Go to the “service menu” and in that menu please choose “Clean Sensor”.
Now the fresh water is flushing the sensor and in the same time a clean
water calibration is done.

On every IOPP certificate renewal:

According to resolution MEPC.107(49) § 4.2.11

The accuracy of the 15 ppm Bilge Alarms should be checked at IOPP
Certificate renewal surveys according to the manufacturers instructions.
Alternatively the unit may be replaced by a calibrated 15 ppm Bilge Alarm.
The calibration certificate for the 15 ppm Bilge Alarm, certifying date of last
calibration check, should be retained onboard for inspection purposes.
The accuracy checks can only be done by the manufacturer or persons
authorized by the manufacturer.

On the JOWA 15PPM Bilge alarm it is only necessary to replace the sensor
unit.
With the sensor, a calibration certificate with the last calibrating date will follow.
