The TRAINLINK . ATX does not require the use of a SmartPack battery. It is equipped with an air turbine generator that operates over a pressure range of about 50 to 125 psi*. It will operate in the same environmental conditions as a standard EOT.

*Note: TRAINLINK . ATX (Air Turbine) EOTs should not be routinely operated at pressures greater than 100 psi, since this may significantly shorten the projected lifespan of the unit.

Air must be applied to the EOT for startup. When air is present on the EOT, the alternator supplies electrical power and charges the back-up battery. Arming and pre-departure procedures will be identical to present battery powered EOT operations. However, the read out information is different than the existing equipment. The TRAINLINK . ATX will scroll through the following displays on each button press.

When air is removed from the TRAINLINK . ATX, a back up battery powers the EOT for four (4) hours. If after 3 hrs. and 55 min. air has not been re-applied to the EOT, the EOT will transmit a "NO AIR" message for five (5) minutes, then the EOT will shut down. When air is re-applied, the EOT will wake up automatically and begin to "trickle-change" the back up battery. However, when the air pressure on the EOT is less than 50 psi, the air generator will supply sufficient power to operate the EOT, but will not charge the back up battery.

The TRAINLINK . ATX will function normally even if the back-up battery is dead. In the event of an emergency brake application, which would remove the air source, the energy stored in the air turbine’s flywheel will be sufficient to complete the emergency command at the EOT.

While operating on the battery the TRAINLINK . ATX will transmit the message "REPLBAT" (replace battery) to the LCU when the voltage drops below 10.5V. If air is applied, the voltage will climb above 11.0V and the EOT will send a "clear" message. Additionally, no "DEADBAT" (dead battery) alarm will be sent. However, if the voltage continues to drop to below 9 volts the system will shut down after a delay of 4 minutes. This prevents deep-discharge of the battery.

As in standard EOTs, the TRAINLINK . ATX shuts down on the tilt-to-horizontal. However, it must remain tilted for a period of approximately 5 minutes to completely shut down the Battery Micro Controller. When the unit is restored to the upright position, and air is applied, the EOT will automatically wake up.

Messages displayed on the LCU will be the same except that the following displays will have a specific meaning when operated with the TRAINLINK . ATX.

Air from the brake pipe serves as the supply for the TRAINLINK . ATX air turbine. Air passes through a filter assembly and then through a small nozzle that directs the high velocity air onto the turbine blades. Airflow through the air filter/nozzle assembly can be verified by applying pressure to the EOT and observing the generator output on the EOT’s display. At 80 psi input, the generator output should be no less than 25 Vdc (G25 or higher will be seen in the EOT display). This information is also transmitted to the LCU and displayed in the Charge Units field.
