APPENDIX 2:

Installation instructions for HP-1M warming plate

for use with TCAT-2LV and TCAT-2DF controllers

Check contents of package carefully to verify contents comprising:

1. HP-1M Warming Plate

2. 3 foot long connector cable (Other lengths can be made to order)

INSTALLATION INSTRUCTIONS

1. Attach the round 7-pin connector to mating socket on rear of TCAT-2LV or TCAT-2DF. The
connector is mechanically polarized to prevent incorrect insertion. Once inserted, rotate the outer
ring at the tip of the connector 90° in a clockwise direction to lock in place.

2. Attach opposite end of cable to the HP-1M warming plate. This connector is also polarized
to prevent incorrect insertion and has a built-in locking tab to prevent accidental removal. To discon­nect from warming plate press down the locking tab and pull back.

3. A Platinum RTD Sensor built into the plate signals the controller to prevent it from overheat­ing. Power to the plate is interrupted if the plate temperature exceeds 42° centigrade. If higher plate
control temperatures are required, please call our service department for instructions on how to
change the set point.

4. A second sensor (Type T thermocouple), described in the Operating Manual for TCAT-2LV
and TCAT-2DF, provides feedback control in the system. For rats this would normally be RET-1
flexible rectal probe and for mice the IT-18 can be used.

If you have questions about a specific application, please call our engineering department at

973-779-5577, ext 15. Or e-mail us at [e-mail]

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 (heating pad or blanket) the Low Voltage 7-pin Output Socket on the rear of the
controller

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

4. Turn on controller Power Switch (rear panel).

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.

TCAT-2 CONTROLLER

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.
