700XA not responding - 3v power diagnostic LED shows orange

Hello - I have a 700XA installed several thousand kilometers away, which has stopped working - I'm not onsite so information is 2nd hand....

I've asked them to check the Power LEDs, most are green except for the 3V is showing Orange colour

I checked the user manual which states the LED should either be Green or 'not lit' - it does not mention Orange

Can anyone confirm if the manual is correct or not.

I asked them to measure the voltage on the 3v test point, they read 3.35v

kind regards, Phil McKay. Melbourne Australia.

  Hi Phillip
  Please make sure you check the voltages, if 3Volts is not solid green means there is an issue with the Base I/O Board , please see the information below for your reference:
  The backplane has a set of test points that allow you to measure the voltage output of the
  Base I/O card. Each test point is labeled with a voltage value that, when measured with a
  voltmeter, should give a measurement equal to what is displayed on the label. A reading
  that does not match this label may indicate a faulty Base I/O card. Try swapping out the
  suspect card with a different one, and take another measurement. To get a measurement
  for a test point, touch the voltmeter’s negative probe to the D GND test point, and touch
  the voltmeter’s positive probe to the desired test point.
  The following test points are associated with the following GC components:
  Test Point GC Component Tolerances
  24V (Regulated) GC power ±2.4V
  17V Preamp (Input for the bridge circuit) ±0.5V
  12V Optional I/O cards ±0.6V
  5V1 System chips ±0.25V
  3.3V System chips ±0.15V
  FVIN, F GND Field voltage input and ground ±0V - 3V (21v - 30v)
  SV1, SV2 Solenoid voltages that drive the heater/solenoid card ±2.4V
  The input voltage range for DC/DC power supply is between 21 and 30 volts. The input
  range for AC/DC power supply is 90 - 264 volts (auto-ranging).
  Voltage LEDs
  Hope this Helps

  Thanks Ray for your response.
  I was more curious about the meaning of the Orange LED indication as it's not mentioned in the manual
