Hawk Gladiator Acoustic Switch Quick Start

Blocked Chute Detection
Principle of Operation
The Gladiator Acoustic Switch uses Acoustic Wave technology in a
new Sender/Receiver form for blocked chute detection. The Gladiator
Amplifier powers two Transducers which use special Hawk developed
software where both units pulse & receive each others Acoustic echoes.
When the path between the Transducers is blocked the units immediate-
ly detect the change of the return signal and trigger a communications
relay for indication or control purposes.
Hawk's Acoustic Wave Transducers are self cleaning. The Acoustic
Switch is designed for continuous operation in dusty, wet environments
where other technologies fail. The power of each pulse (pressure wave)
blows the water, moisture & build-up off the face of the diaphragm.
Two Acoustic Switch Remote Transducers with
UHMW flush mount sleeve & FA4A-4 flange mount.
Transducer Setup
Gladiator Acoustic Switch transducer pairs leave the factory
programmed as pairs (marked TD1 and TD2). A single transducer
may need to be initialised.
If your amplifier is displaying 'error 01' or 'error 11' with a
reset loop you will need to enter the advanced menu to initalise
the transducer. See the full version manual for information on
transducer initialisation.
If on power up you are prompted by the unit to 'press cal to
initialise' follow on screen instructions. If you are seeing 'error
01' or 'error 11' continually most likely one of the transducers
has not been initialised correctly. See the full version manual for
information on transducer initialisation.
Cable Extension
If using a cable run or extending the Hawk supplied cable use
Belden 3084A cable. Hawk supplies lengths of this cable. For
customer supplied cable junction boxes seperate the shield
cable at the terminals of the junction box. The shield should
only have one ground point through the cable run which is the
Gladiator amplifier 'black' terminal along with the black wire as
per the cable which is potted to the Transducers.
It is preferable to have no extra connection points between the
Transducers and the Hawk supplied junction box. Transducers
can be ordered with 50m potted cable.

or slightly (<2mm) protruding.

Note: Other flange sizes available upon request.
For vessels with falling product the transducers MUST be flush
mount with the vessel wall. For heavy falling product chutes the
titanium face 15kHz version is recommended along with welding
a protective hood above each transducer (not in front of).
The transducer has a specially designed UHMW seal which must
either be perfectly in line with the vessel wall interior or slightly
(<2mm) protruded. It should not be recessed in the vessel wall.
Pipe Specification: 4-00" Z40 ID = 100mm Black Pipe
The closest point of the mounting flange when fully screwed on
will be 95mm from the face of the transducer. Take note that
this 95mm should theoretically be the flush mount point for the
transducer face in the vessel.
Alignment - The transducers need to be as accurately facing
each other as possible. No special rotation required. 'Alignment'
software not required.
