1.1 Protection of the TEC element
·
Limit of the TEC current in all operating modes
Protection against thermal destruction.
·
Protection of the sensor
Protection against use of incorrect temperature sensors; protection against interrupted
connection of the temperature sensor.
·
Contact protection of the TEC element (open circuit)
Protection against cable damage, bad contact or TEC element with too high resistance.
·
Control LED for TEC current on
Protection against accidental turning off the cooling.
·
Overtemperature protection
Protection against malfunction caused by internal overheating of the controller.
·
Line failure protection
The TEC current is switched off immediately if a power failure or line interruption occurs. In
this case, same as after turning on the controller, the TEC current remains switched off and
can be switched on manually only.
1.2 Safety
Attention
All statements regarding safety of operation and technical data in this instruction manual will
only apply if the unit is operated correctly as it was designed for.
All modules must be operated with proper shielded connection cables only.
Only with written consent from Thorlabs may changes to single components be carried out or
components not supplied by Thorlabs be used.
This precision device is only serviceable if properly packed into the complete original packaging
including the plastic foam sleeves. If necessary, ask for a replacement package.
Prior to apply power to the TED200C controller, make sure that the protective conductor of the
3 conductor mains power cord is correctly connected to the protective earth contact of the
socket outlet!
Improper grounding can cause electric shock with damages to your health or even death!
Also make sure that the line voltage setting of the fuse holder at the rear panel agrees with your
local supply and that the corresponding fuses are inserted. If not, please change the line
voltage setting (see section
) and the mains fuses (see section
).
The TED200C controller must not be operated in explosion endangered environments!
Do not obstruct the air ventilation slots in housing!
Do not remove covers!
Refer servicing to qualified personnel!
Attention
Use only duly shielded connection cables for laser, photodiode and control input/output
connections.
