Operation
System Power
The SmartSeal system operates on 12VDC (+/-3VDC).
The Main Control Unit and Remote Monitoring Units are connected to each
other using standard NMEA network hardware components. Use of this
hardware allows the SmartSeal system to be easily added to (and be
powered by) an existing NMEA 2000 network.
If no existing network is available, a suitable power source must be
connected (thus creating a private SmartSeal network). The system is
designed such that you can plug or unplug it from its network whether or not
it is powered.
Operating the System
The SmartSeal Temperature Sensor is an autonomous system. It
continuously monitors shaft seal temperature(s) and reports results as visual
and audible indications on the Main and Remote unit front panels. It also
broadcasts shaft seal and engine room temperature measurements on the
NMEA 2000 network for display on MFDs, etc.
Proper operation of the system is very simple:
If a WARNING or CRITICAL ALERT occurs, the condition must be
immediately resolved.
External Siren
The External Siren is an optional component which is typically installed on
larger vessels where engine rooms can be quite loud and are located some
distance from the main helm station. There are several options for the types of
sound the siren will emit which can be selected at the time of installation.

Cabling
The SmartSeal system uses two types of cabling to connect the various
components:
A custom harness is supplied for connecting the Shaft Seal sensor, Neutral
Safety Switch and External Siren to the Main control unit.
Standard NMEA network cables and hardware are used to connect the power
supply and Remote Monitoring Units to the Main control Unit.

Shaft Seal Sensor
Connected to the Main Control Unit, The Shaft Seal Sensor is attached to the
water injection fitting on the SureSeal. It is held in place by a clamp-on
connector located just below the blue water pick up line running to the engine.
While it should not require any maintenance after installation, it should be
inspected periodically to be sure it is securely attached and in good contact
with the injection fitting.
