Brookfield Temperature Controller, Model 106 - Manual (Page 9)

Brookfield Engineering Labs., Inc. Page 9 Manual No. M/98-206-A0402
IV.7 REMOTE
The Remote LED
The REMOTE LED is illuminated when an RS-232C cable (Brookfield Part No. HT-106 for con-
necting 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.10 Piezo Buzzer
The unit includes a buzzer which will provide an audible tone (beep) in the following situations:
• During the Programmable Temperature Controller startup sequence.
• When a temperature/time program has been completed.
• If an illegal data entry has been made (e.g. attempting to set a temperature above or below the
allowable inputs).
• If the temperature probe is removed.
V. PROGRAMMABLE TEMPERATURE CONTROLLER OPERATION
V.1 Powering Up the Temperature Controller
The Programmable Temperature Controller is turned on by placing the rear panel mounted ON/OFF
switch in the ON position. The buzzer will beep and, after a few seconds, the digital display will
indicate the present temperature of the Thermo container. When the unit is initialized, all of the
indicator LED’s are off. The
REMOTE LED will be illuminated if the Programmable Temperature
Controller is connected to an external device through an RS-232C cable.
V.2 Control Modes
The user can select one of three control modes.
In the MANUAL or SINGLE SETPOINT MODE, the Programmable Temperature Controller func-
tions as a single setpoint controller. The user sets a desired temperature, presses the
RUN/STBY key
and the unit will control the Thermo Container at this temperature indefinitely until the unit is shut
off, or a new setpoint is entered and run or the Programmable Temperature Controller is placed in the
standby mode.
In the PROGRAM MODE, the Programmable Temperature Controller functions as a multiple setpoint
temperature controller. The user may define up to ten different setpoints in the controller’s memory.
The user must also define the time interval which will be used for each temperature setpoint (up to 15
hours 00 minutes per setpoint). The user may then run this pre-set program and the Programmable
Temperature Controller will automatically execute the program. The Thermo Container will be con-
