9. Error messages
Typically, an error message is displayed above all content, and requires a key-
press (using the OK button) to clear the error. A small LED indicator light on the
front of the PSU indicates an error (red light).
9.1 PSU error messages
“PSU HOT”
If the internal temperature of the PSU reaches above +80° / +176 F, the PSU
switches off its light modules, and the PSU displays a “PSU HOT” error. It is rec-
ommended to switch the PSU off immediately upon noticing this error, since this
is a highly atypical case which should not occur under normal conditions (under
the dened operating ambient temperature range for this product).
If the error occurs again or restricts operation, the PSU probably requires main-
tenance; please contact technical support for assistance.
9.2 Light module error messages
“LAMP HOT”
If the temperature of the PCB on the light module reaches above +80° / +176 F,
it is switched off and an error is displayed. The displayed error message includes
information about the location of the overheated light module in a stack, along
with its port.
Check that light module cooling is not restricted. Remove all objects that block
airow around the light module, especially around the fan grating. Push OK but-
ton to clear the error. If light module is still too hot, an error message is displayed
again, otherwise normal operation is resumed.
If the problem persists, the light module probably requires maintenance; please
contact technical support for assistance.
