  • Page 10: Operating Scenarios

    Operating scenarios The Tron SA20 PLB is most effective when placed in a clear and if possible elevated area. Metal objects or people in the immediate vicinity of the PLB may distort the radiation pattern of the radio signal. It is therefore desirable to have the transmitting PLB a few meters clear of such objects.

  • Page 12: Self-Test

    Self-test Self-tests shall be performed regularly to verify that the Tron SA20 PLB is working correctly. Jotron recommends performing one self-test every month, and one extended self-test instead of the normal self-test every third month. Performing self-tests more often will affect battery life.
  • Page 13 The test indicator will light up with green light for 3 seconds if the self-test is successful. If the self-test detects a fault in the PLB module, the test indicator LED will start flashing red at the end of the test. For fault codes see the table in chapter 3.5.3.

  • Page 14: Extended Self-Test

    3.5.2 Extended self-test The extended self-test includes a GNSS test in addition to the normal self- test. To start the extended self-test press and hold the black test button for a minimum of 7 seconds. Keep holding until both the yellow test indicator and the green GNSS indicator lights up.

Failure indication Number of flashes Battery failure Transmitter failure No position...
  • Page 17 Contact your service partner if this does not help. 3.5.4.3 No position The GNSS receiver in the Tron SA20 PLB needs a free view of the sky to get a position within the time limit. Windows and canopies will also reduce the signals from the satellites.

  • Page 18: Deactivation Of The Plb

    Deactivation of the PLB If the PLB has been accidentally activated or if you want to deactivate it after use, press and hold the PLB Off button for 4 seconds. All three indicators will light up when the button is pressed. Keep pressing until all lights are turned off.

  • Page 19: Product Description

    Product description The main purpose of the Tron SA20 PLB is to alarm the SAR authorities in a distress situation. When activated the PLB will transmit a signal, which includes the ID of the ship in distress and the position of the PLB. The strobe light will start flashing in both visible and infrared light.

  • Page 20: Controls

    The Tron SA20 PLB is equipped with two buttons. A red activation button that is hidden behind a tamper proof cover, and a black button that is used to start self-tests and to turn the Tron SA20 PLB off after activation. Page 20 of 38...

  • Page 21: Indicator Lights

    Indicator lights The Tron SA20 PLB is equipped with a white strobe light and 3 colored LED indicator lights with associated icons. See the tables below for descriptions and possible statuses. Indicator lights icons Icons GNSS Test Description (Green) (Blue)

  • Page 22: Infrared (Ir) Light

    Infrared (IR) light To enhance visibility for SAR teams using night vision goggles and systems, the PLB is equipped with an infrared (IR) light in addition to the visible strobe light. The IR light is located at the top of the PLB, next to the strobe light, and will start flashing automatically when the PLB is activated.

  • Page 23: Rls Information

    RLS information This PLB has RLS capability. For more information about RLS see chapter 7.10 If the PLB has the RLS protocol enabled the text RLS will appear as shown in this figure. If the PLB does not have the RLS protocol enabled the text RLS will be masked.

  • Page 24: Registration

    Registration Registration of the PLB Your PLB must be registered before use. This allows the SAR authorities to retrieve information about you and your emergency contacts in an emergency. Which again enables them to contact you to determine if the distress signal from the PLB is a false alarm, and an expensive rescue operation can be avoided.

  • Page 25: Change Of Ownership

    Change of ownership If the ownership of the PLB is transferred, the PLB must be re-coded and re-registered on the new owner in accordance with local rules. Testing and maintenance To ensure reliability and to minimize the risk of false distress alerting it is important that the PLB must undergo testing and maintenance as described in this chapter.

  • Page 26: Battery Expiry Date

    The battery expiry date can be found on a label located on the transparent top on the back side of the PLB. The Tron SA20 PLB is fitted with special lithium batteries, and it is not possible to replace the batteries. The PLB must be replaced when the battery expiry date has passed.

The PLB should then be replaced earlier than the date stated on the battery expiry label. If not the quoted 24-hour operating life of the PLB may be reduced.

  • Page 31: Cospas-Sarsat System

    When the Tron SA20 PLB is activated (1), the next passing satellite (2) will detect the transmitted signal and relay it to an antenna at a LUT (3). The signal will be routed from the LUT to an MCC (4).

  • Page 32: 121.5 Mhz Homing Signal

    SAR vessels. Position receiver (GNSS) Jotron PLBs have a built in GNSS receiver capable of receiving position signals from GPS, GLONASS and Galileo satellite systems. The position is encoded by the message generator of the PLB and transmitted to the Cospas-Sarsat satellites.

  • Page 33: 7.10 Rls System

    7.10 RLS system This PLB sends a Return Link Service status together with the distress signal on 406 MHz when it is activated. When this message is received by the ground station, an acknowledge signal is returned to the PLB through the Galileo position system.
