Temperature Controller:
The temperature controller provides a separate digital display for setpoint
temperature as well as process temperature. Buttons are provided on the front
panel for configuring the controller. The CL900A/CL950A is shipped pre-
configured. The customer should not alter any parameters except for the
displayed engineering units (°F/°C).
P.I.D. Indicator:
When this light is illuminated, the unit is heating up the target plate.
NOTE:
P.I.D. Control:
Proportional, integral, derivative control ( P.I.D.) is a temperature control algorithm used in
high-end temperature controllers. The controller causes the process to attain the desired
temperature by turning the process on or off. The process may be a heater or refrigerator. As
the process temperature approaches the setpoint temperature the hot or cold process will be
pulsed to reduce the corrective measures and minimize overshooting. The controller provides
a visual representation of the process status through LED indicators. An indicator may be lit
continuously, blink or shut off entirely to indicate that the process is on, being pulsed, or off,
respectively.
