Remedies for outputs of [ALARM] and [ERROR]
warning signals
When the [ALARM] or [ERROR] external signal is
output, the UJ20 operation is under a warning condition.
Take appropriate actions by referring to the table below.
When [ALARM] is output, the [READY] signal is on,
and UV irradiation is possible. When [ERROR] is output,
the [READY] signal is turned off, and UV irradiation is
not possible.

Status
The LED head temperature has reached the
Temperature warning
warning level during UV irradiation.
The UV irradiation continues.
The LED head temperature has exceeded the
warning level during UV irradiation.
The UV irradiation stops.
There are less than 30 hours remaining before the
LED replacement
total irradiation time of the LED reaches the preset
warning
replacement print.
The total irradiation time of the LED has reached
LED replacement time
the preset LED replacement point.
The UV irradiation stops.
Interlock emergency
The interlock contact, [EMER], was opened during
stop
UV irradiation.
Irradiation incomplete
The irradiation was stopped before completion.

pattern is not connected.
LED wire broken
LED circuit opening was detected during irradiation.
LED short-circuited
LED short-circuiting was detected during irradiation.
Calibration error
The UV intensity did not reach the set intensity.
Cause
The head is overheated because the size of the head
mounting bracket was inadequate.
Review the choice of the head mounting bracket.
Press the [POWER] SW during UV irradiation to check the
LED head temperature.
Replace the head and reset the total irradiation time.
Hold down the [TIME] SW and select the channel of the
head to be replaced.
Press

Hold down [SET] to go back to the operation mode.
Ensure the safety and then short the interlock terminal,
[EMER] (11), and terminal (12).
The [STOP] external signal was input, or the [EMISSION]
SW was pressed, and the UV irradiation was stopped before
completion.
Clarify and remove the cause.
Hold down the [SET] SW and input the [STOP] signal again
to reset the error.
Hold down the [SET] SW to reset the error.
Connect the required head.
Hold down the [SET] SW to reset the error.
Turn off the power and check the cable and head.
Replace them if necessary.
The UV intensity calibration may be impossible depending
on the head installation position and the lens type. Decrease
the intensity setting and then retry the calibration.
It is also possible that the lens is stained or that the head
intensity has decreased.
