“FAN SLOW”
If the PSU detects that the cooling fan of the light module is not rotating, or is
too slow, this error message is displayed. This error message indicates the loca-
tion of the light module in a PSU stack, and its port.
Visually check if the fan is rotating. Make sure there is no dust, debris, or other
foreign objects obstructing the fan. Reconnect the light module and see if the
error occurs again. If the problem persists, the light module probably requires
maintenance; please contact technical support for assistance.
“WRONG LAMP”
If an unsupported light module is connected to the PSU, this error message will
be displayed. This message also appears if the light module conguration data is
missing or corrupt. Reconnect the light module and see if the error occurs again.
If the problem persists, the light module probably requires maintenance; please
contact technical support for assistance.
