Adjust I Share
Turn on the I share, if it was if disabled, by pressing key (F25) for at least one second. The
sensor LED (F19/F20/F21) stops flashing if the I-share is enabled.
Change set temperature again repeatedly for ± (1...2)°C around room temperature while
observing the settling behavior of the actual temperature.
Increase the I share gradually by turning potentiometer (F24) clockwise.
Higher values will accelerate the settling to the set temperature. Too high values will increase
the amplitude and number of overshoots. The I share is set correctly when the actual
temperature reaches the set temperature in short time with at most one overshoot.
3.2.3 Over-Temperature Protection
The TED200C controllers come with an internal over-temperature protection. If the internal heat
sink is overheated, the output of the controller is disabled automatically. The LED "OTP" (F5)
lights up and a short beep is heard. The TEC current is switched off immediately. Pressing the
key "TEC ON" (F9) has no effect in this case.
After the internal heat sink's temperature decreased for about 10°C, the LED "OTP" (F6)
extinguishes and the laser current output can be switched on again.
3.2.4 Disabling the Beeper
If audible signals are unwanted, the beeper can be disabled in this way:
· Press and hold the key “UP” (F18).
· Press the key “Down” (F17). Now the beeper state is displayed:
· “Sd.ON” - Sound ON
· “Sd.OFF” - Sound OFF
To change the beeper state, hold the key “UP” pressed and toggle the beeper state by pressing
"DOWN" key.
