Initial Configuration and Usage

Direct Startup

  1. Check that the chiller coolant is above the minimum level. Important! If the coolant level is below minimum, top up the coolant before starting the system.
  2. If a water to air chiller is fitted, turn on the green main switch on the chiller front panel. The switch illuminates indicating that the chiller is in standby mode.
  3. Turn on the main switch on the power supply front panel. The white Power status lamp illuminates.
  4. Ensure that the Emergency Stop (System Off) button on the power supply front panel is in the active position. (Turn it clockwise to release.)
  5. Insert the key in the key switch and turn the key switch clockwise to position 1. The white Warmup/Ready status lamp flashes to indicate that the system is warming up. The white laser emission warning indicator lamps on the front of the power supply and on the top of the laser head diode module illuminate. The chiller starts to run. Note 1: The key can only be inserted or removed when the switch is in position 0. When the white Warmup/Ready lamp illuminates continuously, the system is ready for use but the shutter is disabled. Note 2: The warm up may take up to 15 minutes.
  6. Turn the key switch to position 2. The shutter is enabled.

Direct Shutdown

  1. Turn the key switch anticlockwise to position 1. The shutter closes.
  2. Turn the key switch to position 0. After a few seconds the chiller switches off. The Warmup/Ready lamp and the emission warning indicator lamps on the laser head and power supply go out.
  3. Switch off the main switch. The Power lamp goes out.

Remote Startup

This assumes that:

  1. The laser power supply main switch is on
  2. The key switch is in position 2
  3. No Emergency Stop has been activated. If fitted, the water to air chiller main switch is on 1. Turn on the AC mains power to power supply and chiller. The Power status lamp and chiller main switch lamps illuminate.
  4. Wait for five seconds to allow the system to initialize.
  5. Send a system reset signal (from the interlock connector or the RS232 interface).
  6. Apply a system enable signal (from the customer interface or the RS232 interface). The Warmup/Ready status lamp flashes to indicate that the system is warming up.
The laser emission warning indicator lamps on the front of the power supply and on the top of the laser head diode module illuminate. The chiller starts to run. When the system is warmed up, the Warmup/Ready lamp illuminates and the shutter is enabled.

Remote Shutdown

  1. Deactivate the system enable signal (from the customer interface or the RS232 interface). The shutter is disabled. After a few seconds the chiller switches off. The Warmup / Ready lamp and the emission warning indicator lamps on the laser head and power supply go out.
  2. Turn off the AC mains power to the power supply and the chiller. The Power status lamp and chiller main switch lamps go out.

Emergency Shutdown

In an emergency either: Press the Emergency Stop (System Off) button on the power supply front panel fully in until it locks or activate any external Emergency Stop device fitted to the complete system.

Restart after an Emergency Shutdown

  1. Release all Emergency Stop (System Off) devices that have been activated and locked in the off position.
  2. Apply a system reset signal (from the interlock connector or the RS232 interface) or turn the key switch to the 0 position.
  3. Perform a normal direct or remote start up procedure.
