8 Warning indications
46
In the event of an error during irradiation, a warning will be displayed on the display panel of the controller (in
operation mode).
■
Temperature warning
When the LED head temperature reaches the warning level during irradiation in operation mode, “TEMP”
(units indicator) will start to flash, and the LED lights next to the switch of the affected channel will turn
orange (mixture of green and red) and the external output signal “ALARM” will be turned ON.
Temperature warning
When the measured LED head temperature reaches the warning level, “TEMP”
(units indicator) will start to flash, and the LED light next to the switch of the
affected channel will turn orange. When the temperature reaches an abnormal
level, an error code (E40) will be displayed and the buzzer will sound, and the
external output signal “ERROR” will be turned ON. When the temperature drops
below the abnormal level the warning is cleared and the warning indicators will
change back to green. If the color does not change to green for a considerable
time, there may be a problem with the LED temperature detection line, such as a
short-circuit. In this case, remove the LED head and the connection cable from
the connector and check the wiring.
■
Time warning
When the warning time is reached in operation mode during irradiation, “×100hrs” (units
indicator) will start to flash, and the “ALARM” external output signal will be turned ON. After
the time warning is detected, “×100hrs” will continue to be displayed until the cumulative time
(head management item) is reset.
Time warning
When the cumulative total irradiation time of an LED head reaches to within 30
hours of the set LED replacement time, “×100hrs” (units indicator) will start to
flash. When the LED replacement time is reached, an error (E50) will be
displayed and the buzzer will sound, and the external output signal “ERROR”
will be turned ON. To reset after this error, hold down the “SET” switch. This
will reset the controller and turn OFF the buzzer and “ERROR” output signal,
but the error code will still be displayed. The error display will be cleared only
after replacing the LED head and resetting the cumulative time.
If irradiation is continued without replacing the LED head, the error message
(E50) will be displayed again and the buzzer will sound.
* To check which channels are subject to time warnings, switch the display mode to show cumulative irradiation time
(×100hrs) for the channel. If the “×100hrs” indicator is flashing, the channel is under a time warning.
