ProtoCessor Module LEDs
PWR LED
When the PT-Link is fi rst powered up, the “PWR” LED should light up
and stay on continuously. See Figure 19. If the LED doesn’t light up,
check that the ProtoCessor is installed correctly and fi rmly connected
to the Base Board.
GPI05 LED
The “GPI05” LED will light up when the Base Board and the Proto-
Cessor Module have established communications. This can take up to 3
minutes depending on the number of units connected to the PT-Link. If
it fails to light up after 3 minutes, check that the ProtoCessor is installed
correctly and fi rmly to the Base Board.
LON LED
When the unit is fi rst powered up, before commissioning has occurred,
this LED will be blinking to indicate the unit has not been commis-
sioned yet. Once the unit is commissioned, the LED will stay off during
normal operations.
LA LED
When the unit is fi rst powered up, this LED should be blinking constantly.
If this LED is constantly on or constantly off, the Module is not working
properly and needs to be replaced.
TX & RX LEDs
These LEDs work together to indicate that communication is being
established with the desired protocol network. If both LEDs are blink-
ing, then communication is working properly. If both are not blinking,
check the protocol network wiring.
If all of these tests are made and the controller still doesn’t operate,
