Power supply diagnostics
There are two LEDs on the front cover of the R3000 power supply unit. They provide basic
diagnostic information on the connections: wiring and power supply connection status.
The following table covers the various possible sequences.
LED
Color
Pattern
Meaning
STATUS
Green
On constant
Output voltage (52 VDC) is
available to the transceiver
POWER
Green
On constant
Input supply is good, voltage is
within acceptable range
OFF
N/A
No supply, or protection fuse is
blown
Red
On constant
•
R3000 switch set to OFF
•
Output overload
•
Input voltage too high (>45 V
DC)
•
Input voltage too low (<17 V DC)
•
Output voltage too high (>60V)
•
Temperature too high (>125° C)
Red
Blinking
Output overload
Ú
Note:
The power supply has an initialization sequence at startup, and will momentarily
illuminate the red LED, this is normal behavior.
Control unit power and alarm output connection
The R3016 Control unit power cable has four wires, two of which provide power to the unit,
and two for the alarm output.
