Configuration of switches, failures (lock-outs) and incidents
F
ailures
These are indicated b
y
the red LED on the
YKlon board.
If no f
ailure is
present, this LED remains OFF per
manently
. When a f
ailure occurs
, this
LED flashes in tw
o sequences
. The first indicates the compressor aff
ected:
One flash f
or compressor 1, tw
o flashes f
or compressor 2, three flashes
for compressor 3 and f
our flashes f
or accesor
ies
, f
ollo

The second indicates the cause of the f
ailure
.

Thermostat DPC-1
When a f
ailure occurs
, and there is comm
unication, the ther
mostat
indicates time and f
ailure (according to the f
ailures tab
le).
Also indicates others indicents of the ther
mostat.
Incidents
Incidents are indicated b
y
the g
reen LED on the
YKlon board.
If no incidents
is present, this LED flashes at a constant frequency
. When an incident occurs
,
the LED flashes in three sequences
.
The first indicates the compressor
aff
ected:
one flash f
or compressor 1, tw
o flashes f
o
r compressor 2, three
flashes f
or compressor 3 and f
our flashes f
or others
, f

.
The second and third indicates the cause of the incident.
Test push-b
utton
- Also shor
tens cer
tain timings and resets an
y f
ailure detected if pressed until
the g
reen LED goes ON.
- Also identifies optional accesor
ies and probes connected to the board when
pressed an held until the red LED goes ON.
- Oper
ates as a LonW
or
ks pin ser
vice b
utton.
When pressed it sends the
Neuron ID through the LonW
or
ks netw
or
k.
- If the module is po
w
ered with this push-b
utton pressed and held f
or o
ver 3
seconds
, the setup of the node is cancelled (only used b
