I. INTRODUCTION
The Programmable Temperature Controller is used with the Brookeld Thermosel for measuring
viscosity at high temperatures. The unit includes a solid state proportioning temperature control-
ler, 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 nal 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
Brookeld DV-II+ Pro Viscometer, DV-III+ Rheometer or DV-III Ultra 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 Brookeld.
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. SAFETY SYMBOLS AND PRECAUTIONS
Safety Symbols
The following explains safety symbols which may be found in this operating manual.
Refer to the manual for specic warning or caution information to avoid personal injury
or damage to the instrument.
Precautions
This instrument is not intended for use in a potentially hazardous environment.
If this instrument is not used in a manner specied by the manufacturer, the protection
provided by the instrument may be insufcient.
Brookeld Engineering Labs., Inc. Page 5 Manual No. M/02-207-C0109
IV. 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 IV.1.
Figure IV.1
IV.1 Probe
The probe is a 100 ohm precision platinum RTD (resistance temperature detector) probe (Brook-
eld 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 RTD 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 Temperature Controller is turned on and the RTD Probe is not installed.
IV.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 Temperatures)
Brookeld Engineering Labs., Inc. Page 6 Manual No. M/02-207-C0109
For example, the temperature corresponding to a reading of 2.5 V (2500 mV) would be calculated as follows:
(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 (Brookeld
Part No. HT-88Y) is available from Brookeld.
IV.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:
RS-232C PIN CONNECTIONS

2 Data Out (Tx)
3 Data In (Rx)

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 Remote
mode (indicated by the lit REMOTE LED on the instrument front panel).

IV.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 congured will be indicated on the bottom of the Programmable Temperature Con-
troller. The power consumption at 120 VAC is 400 ma plus the Thermo Container load power.
The power fuse must be a 2A/250V Littlefuse, fast acting type, GMA series or equivalent. This
fuse protects the controller electronics only.
Brookeld Engineering Labs., Inc. Page 7 Manual No. M/02-207-C0109
IV.5 Load
The Thermosel connector is provided to supply power to the Thermo Container. The connector
is 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.
Brookeld Engineering Labs., Inc. Page 8 Manual No. M/02-207-C0109
V. CONTROL KEYS AND DISPLAY PANEL
The front panel of the unit, which includes all user controls and status indicators, is shown in
Figure V.1:
Figure V.1
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 meaning:

This key is used to toggle the units in which temperatures are displayed and entered. The right
