that do not require operating the machine in the DAILY MACHINE INSPECTION portion of SECTION 9 – MAINTENANCE AND ADJUSTMENTS of the Laser System Operation, Safety, and Maintenance Manual. Turn on the Assist Gas supplies. Verify that they are regulated to the required pressures.

2.

Note: The supply pressure must be about 100 PSI (690 kPa) above the maximum desired cut pressure.

Verify that the main electrical disconnect at the rear of the main frame is on. If the electrical supply to the chiller has 3.

been off for 30 minutes or less, then verify that the chiller power disconnect is on and proceed to the next step. If the chiller disconnect has been off for more than 30 minutes, then follow the instructions in this CAUTION note:

If chiller power disconnect has been off for more than 30 minutes, turn the chiller selector switch to STANDbY, turn the chiller disconnect ON, and then wait 8 hours before turning the selector switch to LOCAL or REMOTE. Failure to follow this procedure can damage the chiller. CINCINNATI INCORPORATED recommends leaving the chiller power disconnect ON at all times, unless maintenance or repair procedures require turning off chiller power. Refer to CHILLER WARM-UP

section for more details.

Verify the chiller temperature control set-point is 80.0°F (26.7°C). To enable the control to automatically start and stop 4.

the chiller, turn the chiller selector switch to “REMOTE”. To run the chiller independent of the Laser System control, turn the chiller selector switch to “LOCAL”. In Local mode, the chiller should start immediately.

To operate the Laser System, log on to the Microsoft Windows® - based PC control to start the Laser System

5. CNC/

HMI Software application. If the previous user did not log off, then the CNC/HMI program should be running, proceed to Step 7. If the screen saver is displayed on the control station monitor, then move the trackball or press any keyboard key to restore the CNC/HMI Software Interface display. If the CNC/HMI user interface is not visible, then proceed with the following instructions to log on.

When the control is first powered-up, the Windows Logon screen will be displayed on the control station monitor. To log on, click a user name and enter the corresponding password. There are different user logon levels, starting with the Operator user.

User Logon Levels

Operator: For normal machine operation, select “Operator” for the user name and enter “driver” for the password (without quotation marks). The Laser System CNC/HMI application will start automatically after each Operator logon. The Operator user has access to all user interface controls needed to prepare the Laser System for operation, load and execute cutting programs. Operator has limited access to Machine Configuration settings.

Note: The user name is NOT letter case sensitive. Any combination of upper or lowercase letters can be entered for the user name. The password is case sensitive. The user must enter the appropriate password exactly as instructed.

Manager: The Manager level extends Operator-level access by adding the capability to perform administrative functions such as installing software updates, setting the system date/time, backing-up/restoring files and configuring the automatic backup system. See the Windows Administration topic for more about these administrative functions. The Manager logon level also provides edit access to all Machine Configuration parameters.

Setup: The Setup level combines the administrative capabilities of the Manager level with network/domain setup and configuration capabilities. The Setup level is limited to performing administrative functions. The laser cutting system can not operate using the Setup logon level. To log on to the Setup account, press the “Ctrl + Alt + Delete” key combination twice while the Windows Logon screen is displayed. This will cause a login box to open, enter “setup” for the user name and the corresponding password.

If the

1. CNC/HMI program is not already running, start it now by clicking the ‘CNC LASER’ icon. When the

2. CNC/HMI application begins running, the Alarms and Messages window will display: “Main drives are off”, “Axes have not been homed”, “Tip standoff calibration not completed”, and “Auto Focus Head not homed”. Make sure all personnel and equipment remain clear of the moving gantry. Turn the “DRIVES” selector keyswitch on the Operator Control Station Side Panel to the “ENABLED” position, press the “DRIVES ON” pushbutton and then press the “RESET” button. The “Drives On” indicator on the Control Station Side Panel should illuminate and the Main drives are off message should disappear from the Alarms and Messages window.

Home the machine axes by selecting the “Axes Home” button on the Operator Console Control Bar and then pressing the 3.

“CYCLE START” pushbutton. When the homing operation starts, the “Axes Home” button text changes to “Homing” and the color changes to amber. When all axes have moved to their reference positions, all axis motion stops, the Axes Home function ends, and the control automatically changes to Jog mode.

Rotate the “HIGH VOLTAGE” keyswitch on the Control Station Side Panel to the “ENABLED” position, and then 4.

press the “Laser Ready” button on the Operator Console Control Bar. The laser control will now start a power-up sequence that may take several minutes to complete. While the power-up sequence is in progress,, the “Laser Ready” button will be flashing. When the laser power-up sequence is complete, the “Laser Ready” button will be bright green and not flashing.

Perform the steps in the
