OPERATING INSTRUCTIONS

The TCAT-2 Controller parameters are set at the factory for the specific load supplied with it. If the
TCAT-2 has not been so supplied, see the Operating Manual for adjustment of the control parameters

1. Connect the thermocouple sensor to the blue Feedback Sensor Socket on the rear panel and
position the sensor.

2. Connect the load (lamp or mat, etc.) to the Controlled AC Output on the rear of the controller
(7amp max.) or the Low Voltage 7-pin Output Socket

3 Connect the controller power cord to a suitable AC outlet.

4. Turn on controller Power Switch (rear panel). Set position of Heat/Cool Switch depending on
control protocol (See manual for details.)

5. Set the control temperature:

a) Press SHIFT. A digit will flash.
b) Use UP and DOWN buttons to change
the flashing digit. Press SHIFT again to
select the next digit.
c) When all digits are changed, press SET
to enter new control temperature.

3.0 SETTING UP THE TCAT-2AC CONTROLLER

3.1 Connect a suitable load (500 Watts maximum) to either of the auxiliary AC outlets on the rear
panel of the TCAT-2AC using the auxiliary AC adaptor cable if necessary.

3.2 Insert a type T thermocouple feedback sensor into the blue socket. Ensure that the sensor tip is
securely attached to the load at an appropriate location. Call our Engineering Applications Department
(1-800-452-8510) for more information on sensor placement.

3.3 Connect the AC power cord to the AC input module and to any suitable AC outlet.

1.0 GENERAL DESCRIPTION

1.1 The TCAT-2 is a general purpose autotuning controller for a variety of laboratory applications.

The TCAT-2AC provides two time-proportioning controlled AC outlets for the control of resistive
loads such as heat lamps or warming blankets. It can also be adapted to many different types of load
(maximum 500 Watts.)

The TCAT-2LV provides a low voltage DC output for electrically sensitive applications where AC fre­quencies will interfere with monitoring devices. It can be supplied with a variety of different DC
power supplies depending on the load requirements. The TCAT-2LV uses a dual set point control cir­cuit to prevent a heating element from overshooting the control point. This is recommended in applica­tions such as animal warming tables or blankets where thermal lag in the control system is an issue and
might lead to burns.

The TCAT-2DF combines features of both the instruments described above.

A type T thermocouple probe is used as the temperature feedback sensor and any of Physitemp’s
extensive line of probes can be used for this application.

All the TCAT-2 instruments operate on a 110V - 230V AC supply.
