GND (X5-2)
Power GND related to SV+.
Connect to supply voltage minus.
The base plate is
connected to GND via 10 kΩ.
7.2.2. Peltier element X6
Pin
Name
Function
1
TECminus
Power output to Peltier element minus
2
TECplus
Power output to Peltier element plus
TECminus
(X6-1)
Connection to Peltier element minus.
Voltage:
0 V … Supply voltage
This output pin has to be connected to the minus pin of the Peltier element. It
does not mean, that there is a negative voltage related to the output pin
TECplus
. The polarity on this outputs is dependent exclusively on the
temperature control situation and is not related to GND
Warning:
Do not connect to GND or any other electrical potential.
TECplus
(X6-2)
Connection to Peltier element plus.
Voltage:
0 V … Supply voltage
This output pin has to be connected to the plus pin of the Peltier element. It
does not mean, that there is a positive voltage related to the output pin
TECminus
. The polarity on this outputs is dependent exclusively on the
temperature control situation and is not related to GND.
Warning:
Do not connect to GND or any other electrical potential.
Warning:
Make sure, TECminus and TECplus are not mixed up. If so,
the controller will never come into regulation and will be
unstable. This can lead to sudden shock and damage of
your setup.
The power outputs to the Peltier element are short circuit protected. The short
circuit detector is implemented in hardware and therefore reacting fast (no
software latency).
