I. INTRODUCTION
The Model 106 Programmable Temperature Controller is used with the Brookfield Thermosel for
measuring viscosity at high temperatures. The unit includes a solid state proportioning temperature
controller, a means for entering the desired temperature/time data and appropriate status indicators.
The Programmable Temperature Controller can maintain a constant temperature in the Thermosel or
be programmed to effect temperature changes. The program indicates each desired temperature and
the period of time that the Thermosel should be maintained at that temperature. In this manual, a
time/temperature combination is termed an “entry” or “step”. A program can have up to 10 entries.
The Programmable Temperature Controller can automatically stop maintaining the temperature of
the Thermosel Container at the termination of the program. Alternatively, the Programmable Temperature Controller can be programmed to maintain the final preset temperature at the termination of
the program.
The front panel is used to display and edit temperature/time programs. The front panel also presents
the status of the system (e.g. the current temperature of the Thermosel and error messages).
An RS-232C communication channel is provided to establish control and/or observe operating parameters via a remote device (e.g. a personal computer or a remote terminal). Rheocalc, an optional
software package available from BROOKFIELD, can be used, in conjunction with the BROOKFIELD
Model DV-III+ Rheometer, to provide temperature/time inputs to the Programmable Temperature
Controller via a personal computer. (Optional Cable HT-106 is required to interface the Programmable Temperature Controller to the PC.)
An analog output port is available to send temperature data to a strip chart recorder. Optional Recorder Output Cable (Part No. HT-88Y) is available from Brookfield.
A list of the parts shipped with the Programmable Temperature Controller is provided below. If any
parts are missing or damaged, please contact BROOKFIELD or your local authorized representative
immediately.

III. INSTALLATION
Plug the temperature sensor into the Probe receptacle, the Thermo Container into the Thermosel
receptacle, the strip chart recorder (if used) into the Recorder jack and a remote RS-232C device
(again, if used) into the Comm Ports 25-pin plug. The rear panel will appear as follows in Figure 1.

III.1 Probe
Probe

Comm Port
The probe is a 100 ohm precision platinum R TD (resistance temperature detector) probe (Brookfield
Part Number DVP-94Y) which is plugged into the Probe port on the rear panel.
Note: The RTD Probe must be plugged into the Programmable Temperature Controller and
the R TD Probe end must be inserted into the Thermo Container before power is turned
on. The Controller will beep on/off. An error message (0.RTD) will be displayed if the
Programmable T emperature Controller is turned on and the RTD Probe is not installed.
III.2 Recorder
The Recorder jack provides a signal to a recording device (the optional HT-88Y cable is provided for
this service) such as a strip chart recorder. The full scale recorder output signal range is from 0 to 4 V
for the Thermosel systems. The temperature can be obtained from the output potential (in mV) as
follows:
The 0 to 4 volt output corresponds to a temperature range of -100°C (-148°F) to 300°C (572°F).
Realistically , temperatures in Thermosel systems will typically be above ambient. Therefore, output
voltages will generally range from slightly less than 2 volts (<100°C) to the full 4 volts (300°C). The
temperature corresponding to any intermediate output voltage can be obtained from the following:
(0.1 * mV) -100 = °C(Centigrade Temperatures)
(0.18 * mV) -148 = °F(Fahrenheit T emperatures)
For example, the temperature corresponding to a reading of 2.5 V (2500 mV) would be calculated as
follows:
Brookfield Engineering Labs., Inc. Page 5 Manual No. M/98-206-A0402
(0.1 x 2500) - 100 = 150°C or (0.18 x 2500) - 148 = 302°F
The recorder jack is a standard 1/4" phono jack. An optional analog output cable (Brookfield Part
No. HT-88Y) is available from Brookfield.
III.3 Comm Port
The COMMUNICATION PORT provides an RS-232C data link to an external device such as a
computer or remote terminal. The RS-232C pin assignments are:

NOTE: Pin number 13 should be connected to pin 25 on the connector being inserted into the
Comm Port in order to place the Programmable Temperature Controller in the Re-
mote mode (indicated by the lit REMOTE LED on the instrument front panel).

III.4 AC, Power Switch and Power Fuse
The primary power requirement for the Programmable Temperature Controller can range from 85 to
265 VAC; 50/60 Hz and must be connected through the power cord. The voltage for which the unit
has been configured will be indicated on the bottom of the Programmable Temperature Controller.
The power consumption at 120 VAC is 400 ma plus the Thermo Container load power.
The power fuse must be a 4A/ 250V fast blow Littlefuse type 3AG 312.5 or equivalent. This fuse
protects the controller electronics only.
III.5 Load
The Thermosel connector is provided to supply power to the Thermo Container. The connector is
Brookfield Engineering Labs., Inc. Page 6 Manual No. M/98-206-A0402
specially keyed so that other loads cannot be readily substituted. The power limit supplied by this
connector is 300 watts.
Note: The current provided to the Thermosel connector is potentially dangerous. Do not insert
or remove the Load plug while power is applied to the Programmable Temperature Controller.

The digital display is used to display system status, to set up temperature/time programs, to review
temperature/time programs and to present certain messages to the user.
The allowable range for temperature entries is:
0.0°C to 300.0°C (32.0°F to 572.0°F), with a minimum increment of 0.1° (either scale). The
allowable range for time entries is from 1 to 900 minutes with a minimum increment of 1 minute.
If a proposed temperature value is above the maximum input for that unit, or if a proposed temperature value is below the minimum input for that unit, an audible sound (beep) will be heard and the
current maximum (or minimum) value will be displayed.
The various buttons and light emitting diodes (LED’s) have the following functions or meanings:

°F
The °F/°C key
°C
This key is used to toggle the units in which temperatures are displayed and entered. The right
most digit in the main display indicates the units currently being used (F = Fahrenheit; C = Centigrade).
IV.2
RUN
STBY
The Run/Stby Key
The RUN/STBY key initiates or stops operation of the Programmable Temperature Controller. To
initiate a temperature program or single setpoint operation, press RUN/STBY. The LED labeled
RUN will light up to indicate the present status of the controller . When the Temperature Controller is
operating, pressing the RUN/STBY key will place the unit in a standby mode and cease control of
the Thermo Container.
IV.3
SET
The Set Key
The SET key is pressed when the operator wants to view or edit temperature and time data. In single
setpoint (non-program) mode, the SET key accesses the temperature setpoint. In programmed mode,
the SET key is used to cycle through the time/temperature program and to accept various options
when the user is “building” a temperature/time program.
IV.4
PGM
The Program Key
The PGM key is pressed when the operator wants to establish, review or use a temperature/time
program. The LED labeled PROGRAM is illuminated when the Programmable Temperature Controller is in the program mode.
IV.5 The Arrow (direction) Keys
The ARROW keys are used to increment (or decrement) temperature values and to scroll through
sub-program options where required. When used to input temperatures, a single press of either of
these keys will result in a single digit increment in the displayed temperature value. When large
temperature steps are required, the user will find it simpler to press and hold these keys. At first, this
will result in a slow increment (or decrement) of the display temperature. However, after a couple of
seconds, the display will rapidly increment (or decrement) and the user must be careful not to overshoot (or undershoot) the desired input value.
These keys will not work when the Programmable Temperature Controller is in the run mode.
IV.6 HEAT
The Heat LED
The HEAT LED is illuminated when the controller is providing power to the Thermo Container . The
LED will flash at a rapid rate when the temperature of the Thermo Container is being maintained at
a programmed temperature.
