" PSM STATUS " LED(S) DOES NOT LIGHT UP
·
The associated module has become defective. The unit will still operate
normally as the remaining working modules will share a higher load. The
unit will go into current limit and the output voltage will drop if the load
drawn is more than the combined maximum rated output of the remaining
modules. Reduce the load so that the maximum load drawn is less than the
combined maximum rated output of the working modules.
Remove the defective module and replace with a new module.
OUTPUT VOLTAGE DROPS
·
The unit has gone into current limit as the load being drawn is more than
the combined maximum rating of the working modules. This may also result
if one or more modules has failed . Check that all the modules are
operating properly. If a module has failed, its green LED would extinguish.
Reduce the load drawn to a value less than the combined maximum rated
output of the working modules. If the voltage does not rise to the rated
voltage of 27.6 V, then switch off all the loads. If the voltage in this
condition is also low, switch off the unit and contact technical support
ONE OR MORE "PSM STATUS" LED(S) FLASHES
·
The output voltage of the individual modules is not the same or the forced
shared control circuitry of the module(s) is defective. Adjust the voltages of
the modules to 28 V as explained on page 8.
If the problem still exists, contact technical support.
