Operating Modes
Control Modes
The
TECPak
offers three control modes: constant temperature mode (T Mode),
constant resistance mode (R Mode), and constant current mode (Ite Mode).
Changing the control mode can only be done through the computer interface,
either through
Arroyo Control
, or by sending the
appropriate TEC:MODE
command.
Constant temperature mode uses the sensor constants to calculate the
resistance of the sensor at the desired or actual temperature.
While most users will only need the temperature control mode, the constant
resistance mode allows you to bypass the sensor equation and directly select
the sensor set point. This can be useful when only the desired sensor value is
known, or when the sensor-to-temperature conversion values are not available
for your sensor.
Using Limits
The
TECPak
supports three different types of limits: temperature, sensor, and
current. There is both a temperature high and temperature low limit, and if the
actual temperature exceeds either of these limits, the output will be shut off.
Likewise, both high and low limits exist for the sensor (R limits), and the output
will be shut off if the sensor measurement exceeds either of these limits.
It is important to properly set these limits to protect your device from damage. If
you are uncertain on how to set the limits, please consult with your local
distributor or directly with the factory.
