1.3 Features
• Key-operated power switch
Protection against unauthorized or accidental use.
• Defined states after switch-on
When switching on the ITC5xx with the mains switch the laser and TEC current
outputs are always switched off. The ITC5xx will always wake up in a mode that
can be selected via a DIP switch at the rear.
• Softstart
The switch on delay of the softstart function protects the laser diode against
undesired transients.
• Limit for the laser diode- and the TEC current (hardware limit)
Manually adjustable current limits restrict the maximum allowed current. The limit
values are set with two 25-turn potentiometers at the front panel.
• Interlock
The interlock input realizes several protective functions simultaneously.
• Safety lock to prevent unintentional use
• Cable damage monitoring
• An external emergency switch may be connected
• Application of external automatic protection equipment, e.g. for the temperature
of cooling water
• ON/OFF LED of the laser diode
The laser can only be operated with the interlock input being duly closed.
• Contact protection of the laser diode (open circuit)
If the cable connecting the laser should be interrupted even for a short time during
operation, an emergency switch turns off laser current immediately.
• Contact failure display of the TEC element (open circuit)
Cable damage, bad contact or too high resistive TEC element is displayed with a
LED. The output will remain switched on since also a wrong TEC element can still
provide cooling and thus further protects the laser diode.
