Determine that the IED's originating signal is within standards
.
NOTE
If the Link/Repeater is not connected directly to an IED, determine that the electrical signal
receiv
ed by the Link/Repeater is not corrupt. The Link/Repeater only repeats the signal it is given,
it does not re-clock or re-generate the signal.
• Review the IED's software and protocols. Does the IED have physical "handshaking"
r
equirements and have the appropriate settings on the IED been made to compensate for
these requirements
?
•
Consult factory.
NOTE
The LEDs only illuminate when there is signal traffic and are not illuminated during signal "quiet"
t
imes. The LEDs may "flicker". This is normal operation.
NOTE
Link/Repeaters contain no serviceable parts. Opening the unit will void the warranty.
