Solution
Check power supply to the device.
Check for broken wires.
Check controllers are online and
contributing to the network supply.
Add power supply to boost voltage.
Ensure that all metal in the wall and
surrounding metal is Earthed.
Connect the DyNet shield, wall box and
mounting plate to Earth.
Ensure that unused wires have been
connected correctly to Earthed shield
terminal (for example Brown/Brown-
white pair).
De-energize potential noise sources in
a sequence and run a test to localize
problem. Further segregate cabling
where required and separate Earth
return to minimize noise contamination
on network. Isolate and replace any
non-compliant equipment found.
Solution
Check power supply adaptor and
ensure correct supply voltage and
current.
Check for shorted or broken wires.
Check plug is inserted correctly.
Check for shorted or broken RS-485
wires.
Check voltage at device for correct
electrical values.
Correct the mounting position
