Rockwell Automation 1606-XLS960E-3 Power Supply Reference Manual - Manual (Page 10)

All parameters are specified at 24V, 40A, 3x400Vac, 25°C ambient and after a 5 minutes run-in time, unless noted otherwise.

10. Remote Control of Output Voltage
The shut-down input can also be used to remotely adjust the output voltage between typically 14Vdc and 28Vdc. All
other functions of shut-down input remain the same.
The control voltage is referenced to the main ground (negative output voltage).

Instructions:
1. Set the unit into “Single Use” mode.
2. Set the output voltage adjustment (24-28V) to the maximum desired voltage.
3. Apply a control voltage to reduce the output voltage.
11. Internal Data Logging
A protected microcontroller inside the power supply acquires and stores operating data during the life of the unit. The
data can be downloaded with a small tool and special software by Rockwell Automation service and repair personnel,
even if the unit is faulty. Having the data facilitates troubleshooting. Knowledge of the events occuring just before a
failure allows for a more accurate analysis of the problem.
The data will be acquired with a fixed sampling rate unless the peak detectors trigger due to an abnormal condition.
In such cases, the abnormal condition is properly captured.
Acquired data:
- Family name of unit (1606-XLS), revision of firmware
- Operational hours and expired portion of lifetime
- Operational data; latest 60 values with timestamps of the last 158 minutes of:
Number of over-voltage transients,
Average input voltage,
Peak input voltage,
Inside temperature,
Overloads > 2s,
Missing of one input phase (minimum output load required)
- Failure data; various errors such as:
Internal errors,
Over-temperature shut-down,
OVP,
Long-term overloads,
Remarkable temperatures inside the unit,
….
- Number of turn-on sequences and overvoltage transients
