Recommendations and Requirements
We recommend the use of power cables with a minimum cross-section of
0.5mm2.
TEC-8A-24V-PID-HC uses serial port (COM) to communicate with PC. There
are a lot of desktop applications which can be used to read out data, sending from
the controller and to write in parameters (Advanced version). Below, there are only
a few examples:
● RealTerm (Windows)
● Minicom (Linux)
● PuTTY
If you are able to program, you can also write your own application. There
are a lot of libraries for serial communication in any programming language.
Protection
The system detects a lack of connection with the thermistor and then
switches WARNING LED on. As long as the connection is lost, the driver will not
take any action and the open collector output is grounded.
If the measured temperature exceeds an overriding limit of +70°C in the NTC
10k versions (+120°C in the Advanced -100/+100 version), the Peltier module is
switched off.
If the measured temperature is out of Tmin...Tmax range, the WARNING LED
is ON and the open collector output (OC) is connected to ground. The PID regulator
works normally (unless the overriding limit mentioned before is exceeded). In the
Basic version, Tmin and Tmax are 0°C and 70°C respectively. In the Advanced
versions, Tmin and Tmax have fixed values when the SJ1 jumper is open: 0°C and
70°C respectively in the Advanced NTC 10k version, and -120°C and +120°C
respectively in the Advanced -100/+100 version. In the Advanced versions, Tmin
and Tmax can be set by the user (through the serial connection) and the settings
become valid when the SJ1 jumper is closed.
If the measured temperature lies between +45°C and Tmax, the WARNING
LED is flashing. The open collector output (OC) is not connected to ground. The PID
