Checking Power and Current Readings
If the power reading is below 25V
The field installation is consuming so much power that the Ranger Converter 3000 has lowered the
power on the two-wire, and you should go locate the problem in the field (See Section 8.4, “When there
is a Short Circuit in the Field” [50]).
Note
The current reading can be "normal" in this situation (350-600mA or lower) - this is one of
the Ranger Converter 3000's safety features.
If the power reading is between 25V and 31V
This is abnormal. The Ranger Converter 3000 will keep running normally, but there's a probability you
have a short somewhere - you should go locate the problem in the field (See (See Section 8.4,
“When there is a Short Circuit in the Field” [50])).
If the power reading is between 31V and 35V when no stations are running
In this range you must inspect the current to estimate the health of your system.
The following table tries to give you an idea of whether or not your system is behaving as expected.
You calculate the expected current as
0.5mA x <number of stations>. Though no station consumes
exactly 0.5mA, the figures average out the more stations you have connected to your system.
Important
Troubleshooting is not an exact science and this is not matrix for exactly determining the
health of your system. This table can help point you in the right direction though.
