functioning
Ensure that the SmartSeal Temperature Sensor
is properly connected to the NMEA 2000 network
and is getting power.
If this is a vessel without a NMEA 2000 network,
ensure that the power connector is properly
connected to the “private” network and the 12V
power source is operating correctly.
Verify that the harness cable(s) are
properly connected to the Main control
unit.
Inspect the ring thermistor(s) at the
injection fitting(s) for poor connection to
the sensor cable. If any problem is
found, replace the sensor cable.
This condition is due to a failure
detected in the Main control unit self-test
which occurs on each power up. Other
internal issues could cause the self-test
to fail. In this case, please contact
Technical Support for assistance.
This is the same indication as the power up
flashing Red LEDs above but the error has been
detected while the Main control unit is operating
(vs powering up as above).
Verify that the sensor cable(s) are properly
connected to the Main control unit.
Inspect the ring thermistor(s) at the injection
fitting(s) for poor connection to the sensor cable.
If any is found, replace the sensor cable.
Remote units are designed to enter this state if
no communication is received from the Main
control unit. This condition can also occur if the
Remote unit is not receiving power.
Ensure the Remote is properly connected to the
NMEA 2000 network or the “private” network
created on installation and that it is receiving
power.
Ensure the Main unit is powered and operating.
System Operation
Possible Causes of Alerts
In general, the temperature of the shaft seal may become elevated if there is
a problem with the cooling water supply to the shaft seal which is necessary.
If an alert has occurred, check for the following:
-Twisted, kinked or leaking water pick-up line from engine to shaft seal.
-Water pick-up line has become blocked with debris (sand, rust particulate
etc.)
-Crossover water line (twin engine applications) is either kinked or blocked
when only one engine is running.
-Water pump malfunction
System Self Test
The SmartSeal Temperature Sensor system has a built in self-test function.
When the system is powered on, both the Main Control and Remote
Monitoring units will cycle through each LED color 2-3 times indicating all
internal self-tests have passed and the unit is operating correctly. In
addition, the Main Control Unit will beep one or two times indicating it is a
single or twin engine unit. The Remote will beep once in either a single or
twin engine installation.
Error Indications
If the self test determines that the Smart Seal System is not operating
correctly after power up, the following error indications will be displayed
Red LEDs flashing and audible alarm sounding rapidly.
-Occurs if the system is powered up and there is a problem in one or both of
the thermal sensor connections of the Sensor cable.
All three LED colors are flashing.
-Occurs, while the system is operating, if trouble is detected in one of the
thermal sensor connections.
The Remote Unit(s) have no illuminated LEDs
-This indicates that the Remote unit(s) are either or both not receiving data
from the Main Control Unit or power from the network to which it is
connected.
