Attachment: The sensor’s orientation towards the vessel is
maintained by the steel and nylon attachment rings. The number
of meshes the attachment rings are supported between must be
restricted to avoid unnecessary stress on the sensors fastening
lugs. The use of both nylon and steel attachment rings is
required to secure the sensor lugs if excessive forces are applied
on them. The nylon rings will stretch or break down, but the
steel ring will prevent the sensor from being lost. Note that two
steel rings must be mounted on the same side of the sensor.
Rubber straps: The two rubber bands (E) must be stretched
towards aft, and mounted to the meshes in such a way that the
detection wires are engaged during normal operations. The
angle between the two rubber bands should be appr oximately 70
degrees. Inspect the rubber straps regularly and always before a
new haul. Replace them if you detect visible signs of cracks or
damage.
Sacrificial water switch sensor
If the water switch on your sensor is a sacrificial brass screw,
this screw must be checked every month. Whenever required
due to wear and tear, the screw must be replaced. Refer to the
Operational procedures in the operator manual.
