Main Display: Auxiliary Sensors
Main Display: Digital I/O State
The set point will depend on the control mode you have selected. When in T
Mode, the set point will be temperature. When in R Mode, the set point will be in
the active sensor’s units (ohms for thermistor and RTD, uA for AD590, and mV
for LM335). When in Ite Mode, the set point will be in amps.
Measurements
The second line of the display contains the measurements appropriate for the
control mode. In T Mode, the actual temperature, current, and voltage can be
displayed, depending on the display mode. In R Mode, the actual sensor value
is displayed instead of the actual temperature. In Ite Mode, the actual
temperature is displayed.
No Set Point Error
Because the
TECSource uses a digital PID loop, it will always stabilize at the set
point, and you will never have a temperature offset often found with analog
controllers.
Using Limits
The
TECSource supports four different types of limits: temperature, sensor,
current, and voltage. 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,
as determined by settings in the
Output Off Menu .
