* The same error can occur when the fluorescent lamp has deteriorated over time or fails to turn ON. As
such, if the LED flashes at intervals of 6 sec, check to make sure that the inner side of the glass
around the filament at both ends of the fluorescent lamp has not become black.

Classification
Normal The composite power supply PCB is
operating normally.
Overcurrent The composite power supply PCB
has detected an overcurrent
because of trapped wiring or an
error in a load in relation to +24VR
or +24VU output.
Low-voltage control The difference between the setting for
error in standby +24VR output and the control value in
standby is larger than specified.
Upon detection, error data is sent to
the DC controller PCB. 'E803' will be
indicated on the control panel.
Error in the commu- An error has occurred in the commu-
nication with the DC nication between the DC controller
controller PCB PCB and the composite power supply
PCB, and the communication data is
not renewed for 8 sec or more.
However, LED100 on the DC controller
may not flash or turn ON at times.
'E191' will be indicated on the con-
trol panel.
Low-voltage control The difference between the setting
error during copying* of the +24VR output and the actual
control value is more than specified.
Upon detection, error data will be
sent to the DC controller PCB.
'E803' will be indicated on the con-
trol panel.
+5.1V output control +5.1V output is outside the specified
error range. All outputs of the composite
power supply PCB will be stopped
so that the display indications on the
control panel will also turn OFF.
Check sum error on The CPU on the DC controller PCB
the DC controller has detected a check sum error in the
PCB communication data twice in a row.
All outputs of the composite power
supply PCB will be stopped.
'E1921' will be indicated on the con-
trol panel.
