User Manual
6.3.3 Overload Light is On
CAUSE
Unit is overloaded
Unit is switched to high voltage range.
Current Limit is programmed to a value
that is lower than the load current
6.3.4 Distorted Output
CAUSE
Power source is grossly overloaded.
The crest factor of the load exceeds 3:1.
6.3.5 Unit Shuts Down after 1-2 Seconds
CAUSE
Output shorted
Output grossly overloaded.
-400 Input module failure
Operating load with too high inrush or start
up currents.
6.3.6 No Output and No Lights on Front Panel
CAUSE
Input circuit breaker switched off.
No input power.
-400 Input Power Supply failure
6.3.7 No Output But Front Panel controller is active
CAUSE
"OUTPUT ON" button is turned off.
Current limit programmed down or to zero.
Voltage programmed down or to zero.
Voltage programmed to the wrong output
There is an output on at least one output
but not on the other outputs
REMOTE SHUTDOWN logic line at J32
pin 7 is shorted to D COM or A COM.
Voltage programmed down or to zero.

SOLUTION
Remove overload or check CL setting
Select correct voltage range.
Increase the Programmed Current Limit
value.
SOLUTION
Reduce load
Reduce load current peaks by reducing
load.
SOLUTION
Remove output short
Remove overload.
Have power module serviced
Consult factory for application advice.
SOLUTION
Switch the breaker on.
Ensure 3 phase power is present at AC
input terminal block
Have -400 input supply serviced.
SOLUTION
Press OUTPUT ON so that "ON" LED is
lit.
Program current limit higher.
Program the correct output voltage
Program the correct output phase
Check the 3-phase AC line input. If there
is one phase of the AC line input missing
one or more outputs will be missing.
Remove connection from J32 pin 7.
Program a higher output voltage.
