DIN-1DIMU4 Troubleshooting (Continued)
TROUBLE POSSIBLE
CAUSE(S)
CORRECTIVE
ACTION
Disconnect load to verify
problem persists.
Leave load
disconnected, or
connect to another
channel
LOADS
LED on a channel
is constantly
blinking fast.
Light connected
to dimmer stays
on full brightness. The unit has a
permanent fault.
Contact Crestron for
support.
Check Network Wiring
Use the
Right Wire To ensure optimum performance over the full range of your installation
topology, Crestron Certified Wire and only Crestron Certified Wire may
be used. Failure to do so may incur additional charges if support is
required to identify performance deficiencies because of using improper
wire.
Calculate
Power CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
CAUTION: Provide sufficient power to the system. Insufficient power
can lead to unpredictable results or damage to the equipment. Use the
Crestron Power Calculator to help calculate how much power is needed
for the system (
www.crestron.com/calculators ).
When calculating the length of wire for a particular Cresnet run, the
wire gauge and the Cresnet power usage of each network unit to be
connected must be taken into consideration. Use Crestron Certified Wire
only. If Cresnet units are to be daisy chained on the run, the Cresnet
power usage of each network unit to be daisy chained must be added
together to determine the Cresnet power usage of the entire chain. If the
unit is run from a Crestron system power supply network port, the
Cresnet power usage of that unit is the Cresnet power usage of the entire
run. The wire gauge and the Cresnet power usage of the run should be
used in the following equation to calculate the cable length value on the
equation’s left side.
