3.9 Polarity Check of the TEC Element
Pre-Settings
·
Connect TEC element and temperature sensor. The sensor must be in good thermal contact
to the active surface of the TEC element.
·
Switch on the PRO8000 (-4) / PRO800 system.
·
Select the TED8000 module.
·
Select the correct type of sensor.
·
Set the correct value for I
MAX
.
Polarity check of the TEC element
Observe T
ACT
(or R
ACT
) and switch on the module by pressing the key ”ON/OFF”
·
If T
ACT
(or R
ACT
) runs away from T
SET
(or R
SET
), the TEC element is reverse poled. Change
polarity and repeat the procedure.
·
If T
ACT
(or R
ACT
) is oscillating around the value T
SET
(or R
SET
), the TEC element is connected
correctly, but the P, I and D share values of the control loop are still incorrect. (Refer to
section
)
·
If T
ACT
(or R
ACT
) is settling properly to the value T
SET
(or R
SET
), the TEC element has been
connected correctly, the values for the P-, I- and D-share of the control loop may still need
improvement.
3.10 Connecting the Status Display LED
To display the operating status a standard LED may be used between pin 1 and pin 8. The LED
will light up when the current output is switched on.
