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.
II. Specifications Power Voltage Specifications Input Voltage/Frequency 85 to 265 VAC; 50/60 Hz (check the label beneath the Programmable Temperature Controller for the voltage requirements of your unit) TABLE 2 Controller Voltage Specifications 15°C above ambient to 300°C Range 27°F above ambient to 572°F Resolution 0.1 °C or °F Reading Accuracy ± 0.5°C (between ambient and +100°C) ± 1.0°C (between +101°C and +200°C) ±2.
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. Probe Recorder Power Comm Port Thermosel Input Figure 1 III.
(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.
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. IV.
IV.1 °F °C The °F/°C key 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). RUN IV.2 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.
IV.7 REMOTE The Remote LED The REMOTE LED is illuminated when an RS-232C cable (Brookfield Part No. HT-106 for connecting the Model 106 to a computer) is plugged into the Programmable Temperature Controller. IV.8 RUN The Run LED The RUN LED is illuminated when the temperature of the Thermo Container is being controlled by the Programmable Temperature Controller. IV.9 PROGRAM The Program LED The PROGRAM LED is illuminated when a temperature program is being established, viewed or run. IV.
trolled to a specified setpoint temperature for the specified time interval and then the setpoint will be automatically changed to the next programmed temperature. The programmed setpoints may be of a “RAMP UP” type, “RAMP DOWN” type or a mixture of the two.
5) If the user scrolls to some new setpoint temperature lets up on the or keys and presses SET the key, the Temperature Controller will accept the scrolled-to temperature as the new RUN instead of the SET key, the temperature setpoint temperature. If the user had pressed the STBY controller would have begun controlling the Thermo Container at the new scrolled-to setpoint temperature.
The time required to reach a temperature set point is dependent on a variety of factors such as the ambient temperature and the difference between the desired temperature and the previous temperature. The temperature/time program indicates how long the Thermo Container should be maintained at the selected temperature before the temperature is changed to the next temperature. The Programmable Temperature Controller only allows for constant “hold” time which in this case has been set at 15 minutes. V.
4) The display now reads: 100.00 We have now altered the current program step to correspond to the first entry for Table 7. 5) Press the SET key to accept this value and move to the next program step. 45.0 1 45 is the previously set temperature for the second entry. 1 indicates the second program entry. Enter the desired temperature for the second entry (140) and press the SET key when the correct value has been entered. 6) Continue to enter additional steps for the temperature program.
hÏ l Ë This could just as easily have been displaying the word s‰Ïp if that were the last selected hÏlË/ s‰Ïp decision. It will always on first entry display the last option selected. Here, you are being asked if you want the Programmable Temperature Controller to maintain or terminate the last programmed temperature (290 in our example) when the last program step time interval expires.
to run your program at this time, press PROG key to exit program mode. This is indicated by the PROGRAM LED being extinguished. V.6 Entering A Single Setpoint Temperature Program A single setpoint program differs from the Single SetPoint Operation - Non Program Mode described above in that temperature will be ramped up to and held at a set temperature for the time duration entered in the program time input.
perature Controller will maintain the 160 °C setting until power is shut off or the RUN key is pressed to stop the program. You may have noticed that this single setpoint program using the hÏlË option is exactly the same as the Single SetPoint Operation - Non Program Mode except that we are in the program mode! V.7 Reviewing and Editing An Existing Program To review an existing program, press the PROG key. The PROGRAM LED will be illuminated.
minutes were entered as a hold time, you would see 14 displayed as the time remaining if you were to look at the hold time immediately after its start, and 0 if the hold time were in its last minute. While the Programmable Temperature Controller is ramping up (or down), you can also determine the temperature setpoint for the next step by pressing the SET key twice: once to view the next setpoint temperature and once to see the programmed hÏlË time interval. V.
perature Controller are formatted as a four digit integer number. Setpoint temperatures being sent should first be multiplied by a factor of ten and expanded to four digits with leading zeros if necessary. All temperatures (sensed or setpoint) being read from the Programmable Temperature Controller should be divided by a factor of ten to obtain the actual temperature.
The actual response to the above command will be RS1004F2{CR}. The last digit indicates that the system is in stand-by mode (see Table 8). 4) To change the operating mode, enter RA{st}{CR} at the external device where st indicates the desired state of the controller (as described in Table 8) and must be either a 1 or a 2.
2) The controller is providing power to the Thermo Container, but the temperature sensor is not reporting an increase in temperature. The power to the Thermo Container will be interrupted. It will be necessary to power down the Programmable Temperature Controller and determine the cause of the fault before continuing operation. 3) The Programmable Temperature Controller sensed a temperature higher or lower than its builtin limits. The following paragraphs provide further detail. VII.
eÂÂ The Programmable Temperature Controller will stop control and will stay in this state until the problem is corrected. The only way to correct this error is to power-down (turn off) the Programmable Temperature Controller and then turn it back on. VII.3 High/Low Temperature Limit Error If a temperature outside of the Programmable Temperature Controllers high or low temperature limits is detected, either of the two messages -lÏ- or -h1- shown directly above will be displayed.
