UV irradiation pattern switching
The UV irradiation patterns (TYPE00 to 15) of UJ20 can be switched with
external signals [TYPE Cng1 to 4].
The irradiation pattern can be switched by changing the input status of
the [TYPE Cng1 to 4] signals while the [READY] signal is on.
* While the [READY] signal is off, the irradiation pattern cannot be switched even if
the [TYPE Cng1 to 4] signal settings are changed.
* While the [READY] signal is on, the irradiation pattern can be switched by
changing the input status of the [TYPE Cng1 to 4] signals.
* When a pattern that is not registered in UJ20 is specified by the [TYPE Cng1 to 4]
signals, the pattern is switched; however, the [READY] signal will be turned off.
This is because the unregistered pattern is specified.
* Use a PLC or other transistor output device to input the pattern switching signals.
If a relay is connected, the pattern switching operation may be unreliable due to
contact chattering.
