• Methods of entering a set time and resetting an operation time
In this normal state, this screen prohibits the entry of data so that
data such as operation times is not deleted by mistake.
To enter data, first set bit 1 of parameter No. 15610 (MDS) to 1.
To enter a set time or reset an operation time, position the cursor
on the desired field, using the arrow keys as appropriate, enter a
setting from the MDI unit, and press the <INPUT> key.
No special soft keys such as all clear are not available. To reset
an operation time, set 0.
When the run time of an item being monitored has exceeded the
corresponding set time, the warning signal (F226#0) is issued to the
PMC.
When the run time of any of the following items has exceeded the
corresponding set time, the signal (F226#1-#5) is output:
• Turbo overhaul F226#1
• Turbo oil replacement F226#2
• Chiller water replacement F226#5
• Internal mirror cleaning F226#3
• Optical path length unit mirror cleaning F226#4
9.1.3.3 Discharge-related alarm history display
When the CNC detects any of the following alarms, the CNC
automatically preserves data such as power supply operation state and
displays such data on the discharge-related alarm history screen:
- ALM.4063 R/F power supply error
- ALM.4066 Abnormal discharge start
- ALM.4076 Decreased laser power
- ALM.4088 Abnormal discharge tube voltage
If alarms subject to data preservation are issued, up to five data items
can be preserved. If an alarm is issued besides the existing five alarms,
the oldest data is deleted to preserve the new data. In addition to five
data items preserved for issued alarms, one data item collected at the
end of normal power compensation operation is preserved as normal
data. Thus, data for an alarm issued can be compared with normal
data.
Pressing the [ALARM] soft key displays the discharge-related alarm
history screen. This screen consists of six pages. The first page
displays data collected at the end of normal power compensation, and
the second through the sixth pages display data for alarms issued. To
switch pages, use the "PAGE ↑" and PAGE ↓" keys on the MDI panel.
The discharge-related alarm history screen allows data to be
referenced only. The discharge-related alarm history screen does not
allow preserved data to be modified and deleted. The CNC preserves
the data below when an alarm mentioned above is issued and when
power compensation ends.
(1) Data preserved at the end of normal compensation operation
• Compensation end date
• Compensation end time
• Output conditions (output, frequency, duty cycle)
