TEMPERATURE SENSOR
Temperature Sensor:
Use this dropdown menu to select
the sensor for temperature control. It is populated with all the
available factory- and user-defined sensors.
Bias Current:
Use this dropdown menu to select the bias
current for the temperature sensor. Options are Automatic,
10 μA, 100 μA, 1 mA, 10 mA.
LIMIT PARAMETERS
Current Limit - (A):
Enter the negative current limit for the
thermoelectric here as a positive number in Amps. Maximum
value is model-dependent.
Current Limit + (A):
Enter the positive current limit for the
thermoelectric here as a positive number in Amps. Maximum
value is model-dependent.
TEC In Current Limit:
This indicator will light if the unit is
operating in a current limit condition. This usually happens
when first driving toward a distant setpoint.
Temp Limit Min:
Enter the low temperature limit here in units
chosen by the
Temperature Units
dropdown. Available range
is -99 to 250°C. This value must be less than
Temperature
Setpoint
and
Temp Limit Max
.
Temp Limit Max:
Enter the high temperature limit here in units
chosen by the
Temperature Units
dropdown. Available range
is -99 to 250°C. This value must be greater than
Temperature
Setpoint
and
Temp Limit Min
.
TEC Voltage Limit (V):
Enter the maximum voltage to the
TEC here. This parameter is updated by IntelliTune. Range
is 9 to 18 V.
TOLERANCE & CABLE RESISTANCE
Temp Tolerance:
Defines the temperature window for the in-
tolerance criteria. Range is 0.01 to 10°C.
Temp Time Tolerance (sec):
Defines the time window for
the in-tolerance criteria. Range is 0.1 to 50 seconds. If the
actual temperature stays within
Setpoint Temperature
±
Temp
Tolerance
range for the length of time tolerance, the system is
stable and considered "In-Tolerance."
TEC Cable Resistance (Ohms):
Set the value of the cable
resistance to the thermoelectric in ohms. Range is 0 to 10 Ω.
