Info

Operationthe Auxiliary input is picked, then the output to the radio will be a CLEAR signal as long as therail integrity can be established.When MLK II B receives a radio signal to wake up and verify the integrity of TK#2, MLK II Bwill send a message to MLK II C. MLK II C will receive a wake signal from the track circuit,and MLK II C will respond to MLK II B saying that it verified the integrity of TK#2. WhileMLK II C is still awake, it can also receive a radio signal to verify the integrity of TK#2 for theopposite direction. MLK II C will remain awake and send a response to Radio #3, clarifying theintegrity of TK#2.The same rules apply, as in the previous paragraph. As the train approaches TK#3, a radiomessage is sent from Radio #4 instructing MLK II D to check the status of TK#3. MLK II Dbegins checking TK#3, which in turn sends a message along the track to MLK II C while MLKII C is still awake. MLK II C will respond and send a return message to MLK II D, clarifyingthe integrity of TK#3.4.2.4. Sleep Test ModeEnter TEST Mode by pressing a pushbutton on the SLEEP Board for the direction to be tested.The unit at the other end will wake-up automatically if everything is OK. The units will stayawake for a period of time that is defined in the application by the user.If testing is complete, the operator can either let the units time out or turn the unit OFF and thenback ON. This will remove the signal to the other units and they will go to sleep.If the units are turned OFF, the operator must be aware of the following considerations:1. If the MASTER (EAST) side is turned OFF, the SLAVE (WEST) end will stay awake fora period of time that is defined in the application by the user, after the SLAVE detects theloss of the signal on the track. There is a slight possibility of the SLAVE unit reawakeningthe MASTER end if the MASTER side is turned off immediately after amessage was transmitted, and then the MASTER was immediately turned back on. If thisoccurs, both units will be in TRACK WAKE-UP Mode. The application should be set upso that both units will remain awake until they determine that they are both in TRACKWAKE-UP mode, then they will go back to sleep.2. If the SLAVE (WEST) side is turned OFF, the MASTER (EAST) end will stay awake fora period of time that is defined in the application by the user, after the MASTER detectsthe loss of the signal on the track. There is a higher possibility of the MASTER unit reawakeningthe SLAVE end because, once the MASTER is awake, the MASTER unit willtransmit every 6 seconds, unless the MASTER’s transmitter has been properly disabled inthe application. If this occurs, both units will be in TRACK WAKE-UP Mode. Theapplication should be set up so that both units will remain awake until they determine thatthey are both in TRACK WAKE-UP mode, then they will go back to sleep.4-8 SM6800B 1D1.0032, Rev. 1, November 2010
OperationTo prevent either unit from accidentally waking up the other unit after turning the power OFFthen ON, leave the unit OFF for a period of time that will allow bits to change state which willput the MICROLOK II unit into Sleep mode; again this is dependent upon how the application issetup. This will allow the other end to go back to sleep after loss of communication.1D1.0032, Rev. 1, November 2010 SM6800B 4-9
