5.2.2 PT-Link Module LEDs
Refer to Figure 28 for LED locations.
PWR LED
When the PT-Link II is fi rst powered up, the “PWR” green LED should
light up and stay on continuously. If the LED doesn’t light up, check
that the ProtoCessor is installed correctly and fi rmly connected to the
Base Board.
RX & TX LEDs
During normal operation, the “RX” LED will fl ash when a message is
received on the fi eld port of the ProtoCessor and the “TX” LED will
fl ash when a message is sent on the fi eld port of the ProtoCessor The
“TX” and “RX” LEDs work together to indicate that communication
is being established with the desired protocol network. If both LEDs
are blinking, then communication is working properly. If not, check
the protocol network wiring and the baud rate in the confi guration fi le.
RUN LED
Upon powerup, the “RUN” LED should light up and stay solid for 15
seconds. It should then blink steadily, signifying normal operation. The
Protocessor will be able to access RUINET once this LED starts fl ashing.
RUN2 LED
The “RUN2” LED should blink steadily after power up, signifying
normal operation. The Protocessor will be able to access RUINET once
this LED starts fl ashing.
SYS ERR LED
The “SYS ERR” LED will go on solid 15 seconds after power up and
then shut off. A steady red light will indicate there is a system error on
the ProtoCessor. If this occurs, immediately report the related “system
error” shown in the error screen of the Remote User Interface to Field-
Server Technologies for evaluation.
NODE OFFLINE LED
The “NODE OFFLINE” amber LED will go on solid 15 seconds after
power up and then shut off. A steady amber light indicates the ProtoCes-
sor is not communicating with a device that it is polling.
NOTE:
If all of these tests are made and the controller still doesn’t
operate, please contact WattMaster Controls Technical
