Section 4 – Installation
4.1 Introduction
Before installing the equipment, make sure
Section 2 – Safety
is read and fully understood.
This section explains how to install the Seanet Lodestar before deploying.
4.2 Unpacking and Inspecting
The Lodestar AHRS includes a number of delicate and sensitive electronic components. In
particular, the accelerometers and RLGs that form the Inertial Measurement Unit (IMU) are sensitive
to shock and vibration. If damaged, these components cannot be replaced in the field, and the
complete Lodestar unit must be returned to the factory for repair and recalibration.
Note
Always handle the Lodestar with care. Store the unit in the shipping container until it is ready to
be installed in the prepared location.
Inspect the Lodestar and all the supplied parts on receipt and check the shipment includes all the
items listed on the shipping documents. Inform Sonardyne immediately if there are any parts
missing, or if any of the supplied parts show signs of damage.
4.3 Installation Location
The Lodestar 500 can be installed at any convenient location on the vehicle. However, to gain
optimal performance from the system, identify a location to install the Lodestar 500 that conforms as
closely as possible to the following criteria:
•
If possible, the location should be close to the vehicle centre of rotation under normal
operating conditions.
•
The location must not be subject to excessive vibration or impulse shock.
•
The location must not exceed the environmental limits for temperature defined in
Section
12.2.3 “Environmental”.
•
The location must provide a mounting surface that is of sufficient strength to support the
Lodestar 500’s weight safely and without flexing.
•
The location must provide access for power and communication connections.
•
There must be sufficient space to allow easy access to install the Lodestar 500.
•
Do not store tools, equipment or chemicals where they can damage the Lodestar 500 or
the connection cables.
•
Make sure the Lodestar 500 and its connection cables do not cause an obstruction to
personnel operating in the area.
•
Do not use a location where the connection cables are likely to suffer damage from
mechanical stresses or chemical attack.
