1.2 Features
1.2.1 Safety measures for the laser diode and the TEC element
To protect the connected laser diodes and the TEC elements the combined controller
ITC8xxx contains the following protection circuits:
•
Soft start when switching on the laser diode current
Protection against capacitive and inductive parasitic elements (switching peaks).
•
Software limit for the injection current and the TEC element in all operating
modes and additional hardware limit for the injection current
Protection against thermal destruction of the devices.
•
Interruption control of the connection cable to the laser diode (interlock)
Protection against accidental operation.
•
Contact protection of the laser diode (open circuit)
Protection against cable damage or bad contact.
•
Electronic short-circuit switch for the laser diode
Protection against static discharge when touching the switched off laser.
•
Protection of the sensor
Protection against the use of an wrong temperature sensor / protection against line
interruption to the temperature sensor.
•
Separate on and off function for each module
Protection against operating errors.
•
Separate over-temperature protection for each module
Protection against thermal failure of the module.
•
Control LED for the laser and/or TEC current active
•
Mains filter
Protection against line transients and interferences.
•
Line failure protection
In case of line failure/line damage the combined module must explicitly be
switched on anew since it cannot be taken for granted that all components of the
measurement setup are still working faultlessly.
•
Key-operated power switch
Protection against unauthorized or accidental use.
•
Action check
After power up the combined modules are in LASER OFF mode.
