OUT1…OUT4 LED Meaning
Green Output switched-on
Off No input voltage connected or output active switched off via pushbutton
Green flashing
(2 Hz) Current/power budget exceeded
The sum of the output currents exceeded the permissible total output cur-
rent of the power supply. Outputs with low priority are switched off
Green flashing
(4 Hz) Pushbutton lock It is not possible to switch the output on or off via the
pushbutton.
Possible causes:
n
Pushbutton is locked by “external interface” or “button lock feature”.
n
Interval between charge and switch-on cycles < 5 s (MOSFET protection).
n
Too high temperature at the output.
Orange Pre-alarm: Output switched on, output current exceeds pre-alarm level,
overload imminent.
Orange flashing
(1 Hz) Overcurrent at output due to overload
The eFuse at the output has tripped. The output has switched off.
„ Press pushbutton at the output (OUT1…OUT4) to restart the channel.
Orange flashing
(2 Hz) Installation faulty, cables or connected hardware at the outputs are not in-
stalled correctly. The output has switched off automatically.
„ Switch off channel manually via pushbutton at output (OUT1…
OUT4).
Conditions:
n
PSU with NEC outputs: Difference between positive and negative current
of the output has been >1 A for 6…6.5 s
n
PSU without NEC outputs: Connector negative wire overcurrent accord-
ing to negative trip curve, or Output was contributing to negative over-
current of another output.
Orange flashing
(4 Hz) Short-circuit at output
The eFuse at the output has tripped. The output has switched off (output
current at channel > 48 A).
Possible causes:
n
Electrical short circuit
n Too high loads connected
n
Plugging in a large capacitance during operation
„ Press pushbutton at output (OUT1…OUT4), outputs with eFuse try to
restart automatically.
Orange/green
flashing (2 Hz) MOSFET overtemperature limit reached (125 °C)
The output switches on again automatically when the temperature has
dropped to max. 90 °C.
Red Hardware Fault, MOSFET damaged (short circuit), PSU will be turned off.
Cause: The power switch of a specific output is damaged. Replacing the
power supply may be necessary.
Red flashing
(1 Hz) Hardware of the measuring circuit defective or values outside the permiss-
ible range.
Replacement of the power supply unit may be necessary
Possible causes:
n
The deviations of the internal output current sensors exceed the per-
missible limits.
n
Temperature sensor measurement out of range (-40 °C or +150 °C for
more than 5 s).
