The following table gives some guidelines as to whether or not your system is operating as expected.
Current
Current could be in these ranges depending on
the number of connected stations:
State
Number of connected
stations
20
40
60
80
96
Low current less
than
15%
< 9mA
< 17mA
< 25mA
< 34mA
<
42mA
It is possible that one or
more stations are not
connected correctly. Try
running the test
Program
.
Normal current
15
% to 20%
9
-12mA
17
-24mA
25
-36mA
34
-48mA
42
-60mA
Everything is fine. The
system
is looking healthy.
High current 20%
to 50%
12
-15mA
24
-30mA
36
-45mA
48
-60mA
60
-75mA
You might have a problem
somewhere
on the 2 - ‐ wire
causing an excess
consumption.
Problems that
dramatically increase under
wetter conditions.
Excessive current
greater than 50%
> 15mA
> 30mA
> 45mA
> 60mA
> 75mA
Immediate attention is
required.
Locate the
problem in the field right
away.
T ypically
, the problem
will
be a bad connection or
a cable left
open - ‐ ended in
the
field. Troubleshooting is
identical to when locating
for
short circuits in the field,
but the
current will not be
as excessive as when a short
occurs.
