General Description Sensor Input

This temperature control displays both the setpoint and process temperature and uses the most modern control
technology for the best temperature stability. The Auto-tune feature minimizes setpoint overshoot and learns your
process. Changing your setpoint is easily done with the interface keys. The controller can also perform ramp rate
operations to allow the user to slowly raise the process temperature. There are several input types available. This unit
comes with a 6’ detachable power cord, grid support bracket, which is ideal for fume hood mounting to maximize bench
space. This control is a microprocessor-based, digital indicating, automatic temperature control with a single input and a
single output. It features an auto-tuning function that allows automatic setting of control parameters with a minimum of
user input required. This family of control accepts a type "J", “K”, “T” thermocouple, or RTD (model 3622564) input
depending on the model ordered.

The control automatically sets the PID parameters through a "learning" sequence in the auto-tuning mode. PID
parameters include proportional band, reset/integral and rate/derivative. User-friendly features include automatic LED
indicators to aid in monitoring and setup, as well as dual LED displays for process temperature and set point indication.
This control automatically stores all information in a non-volatile memory.

How to Setup and Operate

First, connect the heater load and the sensor to the load and sensor receptacles on the front panel. Next, plug the control
line cord into an appropriate 3-wire grounded power receptacle. Push the power switch to the "ON" position. Wait five
seconds for the control unit to energize.

The control is shipped from the factory with the display reading in degrees C. If a display in degrees F is desirable, press
the UP/DOWN arrow keys simultaneously for three seconds to access the Setup Page. Press the Advance key until the
Celsius_Fahrenheit parameter [C-F] is shown in the lower display. Press the UP arrow key to change from C to F.

After changing the display, press the Infinity key to display the set point temperature and the process temperature
(temperature at the sensor).

To begin the heating process, use the Up/Down arrow keys to enter the desired set point temperature. This is shown in
the lower display. Auto-tuning is recommended in all applications. Auto-tuning allows the control to set the PID
parameters without those parameters being manually entered/calculated by the user. It also minimizes the amount of
temperature overshoot of the set point and decreases the time required for the process to stabilize. See page 8 for
instruction on performing the auto-tune function.

It is recommended that the auto-tune feature be used every time the process temperature set point has been changed. If
the process is being repeated, the parameters learned in the initial setup are stored in the memory of the control and the
auto-tune process isn’t required to be repeated in most applications.

Control Sensor

Range Type J:

-200°C to 1200°C

Range Type K:

-200°C to 1370°C

Range Type T:

-200°C to 400°C

Range Type RTD:

-200°C to 800°C

Proper placement of the sensor can eliminate many problems associated in the total operation of the system. The probe
should be placed so that it can detect any temperature change with little thermal lag. In a process that requires fairly
constant heat output, the probe should be close to the heating source. In processes where heat demand is variable, the
probe should be placed close to the work area. Experimenting with probe location should be tried to provide optimum
results for your particular process.
