TUNICS T100S-HP User Manual

3.2

Enabling/Disabling the Laser Output

Subject

For laser safety reasons, the TUNICS T100S-HP laser output is not immediately enabled 

after system turn-on and initialization. 
After the initialization routine, the TUNICS T100S-HP is in Disabled mode, as shown on 

the third display (DATA area). 

Procedure

1.

To enable the laser output: in the DATA area, press the 

Enable

 key. 

On the third display, the message 

Disabled

 is replaced with diode current I.

The 

Enable

 LED is lit to indicate that the TUNICS T100S-HP is emitting a laser output.

2.

To disable the laser output: in the DATA area, press the 

Enable

 key again and check 

that the 

Enable

 key LED is off.

On the third display, the message 

Disabled

 appears.

3.3

Shutting Down the Product

Subject

The following procedure explains how to shut down the product. Do not turn on and off 

the system repeatedly and too rapidly.

Procedure

1.

In the DATA area, press the 

Enable

 key to disable the laser output and make sure the 

message 

Disabled

 appears on the third display.

2.

On the front panel, in the OUTPUT area turn the key-lock switch counterclockwise to 

the STBY position.

The message 

Parking

 displays and the optical head is automatically moved to its 

parking position.

3.

Wait a few seconds until complete system shutdown.

4.

If you want to move the product, or if it is not going to be used for a long period of 
time, set the MAINS power switch on the rear panel to the 

O

 position.

5.

If you want to initialize the laser again, wait at least 30 seconds.

IMPORTANT

For laser safety reasons the TUNICS T100S-HP features a Remote 

Interlock connector at the rear-panel that can connect to an external 

remote interlock switch. When the interlock switch is open, the laser 

output is turned off. To enable the laser output, the interlock switch 

must be closed (see section 

Installing the Remote Interlock, p. 23

).

Do not unplug the fiber-optic cable from the laser output connector while 

the laser is still enabled. Exposure to the laser beam is potentially harmful.

WARNING

During system shutdown, DO NOT TURN OFF the system with the rear 

panel O/I switch. The optical head must be parked when transporting 

the product.

Before transporting the product, make sure the system is completely 

turned off.
