NETWORK#
Sets the equipment No. in the range of #00 to #15 before performing remote
operations from the personal computer by external communication function.
TEMP CONT
ALARM
L
H
Sets the control temperature of cooling water.
Sets the alarm temperature range by lower limit value (L) and upper limit value (H).
Usually, it is not necessary to change the set value. When you must change it for a
compelling reason, contact us for information.
<Note>
When the cooling water temperature is below 5ºC, Error No.11 LOW
TEMPERATURE OF COOLANT occurs.
The laser can be used if the cooling water temperature is more than 5ºC but
below the set value of L, the temperature rise is less than 0.3ºC per minute. If the
leaser does not become ready in 30 minutes after turning ON the power supply,
Error No.11 occurs. When the set value of "H" is exceeded, Error No.10 HIGH
TEMPERATURE OF COOLANT occurs.
POSITION
AUTO OFF
Sets the time required for the guide light to go out automatically in the range of 01 to
98 minutes. This can be set in units of minute.
When 00 is set, no guide light is output.
When 99 is set, the guide light does not go out automatically.
SW1
SW1-1
SW1-2
SW1-3
SW1-4 · 5
SW1-6
SW1-7
SW1-8
Sets the functions assigned to 1 to 8 of "SW (SWITCH) 1" to ON or OFF.
1: Sets the high voltage to ON or OFF. At ON, a high voltage is not output at AUTO
START and the screen is displayed in the status of HV: OFF.
2: Switches the laser start/stop control by using the EXT.I/O connector. At ON,
laser start/stop control can be exerted from the PLC connected to the EXT.I/O
connector even in the status of PANEL CONTROL (internal control).
3: At ON, the laser output signal is output from pin No.7 of the EXT.I/O (1)
connector. It is turned ON at the start of the rst shot and turned OFF at the end
of the last shot.
4 and 5: Unused.
6: Switches the measurement accuracy of the measured laser energy value (J).
OFF: x 1 (000.0 J)/ON: x 10 (00.00 J)
<Note> At ON, the maximum peak value of laser output "PEAK" on the SCHEDULE
screen becomes 1.0 kW regardless of the model.
7: Switches the setting range of pulse width (laser output time ms).
OFF: 00.0 ms/ON: 0.00 ms
<Note> At ON, the maximum total value of laser output time (ms) ("FLASH1" +
"FLASH2" + "FLASH3") on the SCHEDULE screen becomes 5.00 ms.
8: Sets to ON to change the setting of No.6 or No.7 of SW1.
<Note>
When the setting of No.6 or No.7 is changed, the set values of SCHEDULE are
initialized. To prevent misoperation, the setting cannot be changed unless No.8
of SW1 is set to ON. When the setting of No.6 or No.7 of SW1 is changed and
the ENTER key is pressed, the setting of No.8 of SW1 is returned to OFF. It takes
about 15 seconds until initialization is completed. The POWER lamp blinks during
that time. Turn o the power supply after blinking stops.
