SAFETY PRECAUTIONS
DANGER: There are no user-serviceable parts in this
instrument. Do not remo ve cover , as high volta ges exist inside the unit. Refer servicing to your dealer .
DANGER: If thermocouples are at a high voltage, this volt-
age will be present at other points inside the unit.
DANGER: For continued fire protection, replace fuse only
with a fuse of the specified current, voltage, and type. Remove power cord from wall socket before checking or replacing a fuse. High voltages exist on fuse terminals.
WARNING: To avoid electric shock, the power cord protective
grounding conductor must be connected to earth-ground.
WARNING: Install an independent temperature limit control
protection system where a fault condition could result in fire or other hazard. Failure to install such a system could result in injury to personnel or damage to property.

INTRODUCTION
This manual provides information for installing and operating the Tempera­ture Controller R/S (advanced model).

APPLICATION DATA
Applications for the Temperature Controller R/S include heating and cooling of solids, liquids, and gases. For all applications, there are certain set-up operations that should be made carefully to assure optimum and safe perf or­mance. The power and type of heater , the positioning of the sensor , the amount of thermal insulation, the flash point of the heated material and the many controller set-up menu options are among the many variables to be consid­ered in setting up the controller.
One of the most important of these considerations is the heater sizing. A heater that is too low powered ma y not be able to raise or ev en maintain the material at the desired set point. A heater that is too high po wered will not maintain precise temperature control and may be unsafe. Because of the many system vari­ables, optimum heater sizing must be determined experimentally; howev er, an approximation can be made through a fe w calculations . These calculations are included in the software program included with the unit.
DESCRIPTION
GENERAL
The Temperature Controller R/S is designed to maintain a constant, pre-set process temperature. It uses a temperature sensor to detect the temperature of the process. Using a microprocessor softw are algorithm, it adjusts a heater or cooler by varying the output duty cycle. The Temperature Controller R/S is a single-loop controller intended for laboratory or industrial applications. The unit can control loads of up to 15 amperes (A).
The Temperature Controller R/S is housed in a rectangular metal enclosure, with plastic bezels on the front and back. All connections are made on the rear of the unit. The display and keypad are on the front. A bail bar, or tilt stand, is used to elevate the front display panel for easy viewing and opera-
3
tion. The unit can also be mounted in a panel with the use of an optional panel mount kit. A two-line, 16-character, 14-segment vacuum fluorescent display is used for display of operating, setup, and alarm parameters.
A number of accessories can be used with this deluxe model of the Tempera­ture Controller, including v arious types of temperature sensors, heating units, cooling units (such as fans or pumps), remote alarms, and recorders.
One of several additional R/S model features (not available in the standard models) is “Ramp and Soak,” which uses a timed sequence pre-set user temperature set points.
The unit also has RS-232-C Serial Communications, so that it can be set up and controlled by a computer. An IBM®-compatible PC (personal computer) disk is included with the R/S controller, along with a separate operator's man ual. It can be used to set up the controller and perform logging and other func­tions. For advanced users, a serial communications specification is included on disk for customized programming.

FIGURE 4. FRONT PANEL DISPLAYS
Vacuum Fluorescent Readout
The vacuum fluorescent readout displays operation and setup parameters. Alarm conditions are also displayed.
UP, DOWN, LEFT Arrows
The UP and DOWN arrow keys will increment or decrement the current val­ues of displayed (blinking) numerals or enable you to scroll through a list where multiple-choice parameters are offered. The LEFT arrow key allows
4
you to change default numeric settings by moving the blinking cursor left to the next most significant digit. When you have reached the most significant digit (furthest left), the LEFT arrow key will move the flashing cursor back to the least significant digit (furthest right).
MENU Key
The MENU key allows you to access all of the user-configurable setup pa­rameters of the Temperature Controller. Pressing the MENU key will scroll through the parameter options, using the arrow ke ys to change those param­eters. Refer to the Setup Procedures section for additional information on each parameter.
SET Key
The SET key allows y ou to change the control setpoint (SP), using the arrow keys. Pressing the SET key again will exit the setpoint mode. In the Ramp and Soak mode, the SET key will toggle the displa y between setpoint and run time remaining. Refer to the Operation section for additional information on changing the setpoint.
ALARM Key
The ALARM key enables y ou to acknowledge temperature control alarm con­ditions and silence the audible alarm. Pressing the ALARM k ey will erase any alarm messages on the display and stop the ALARM from flashing. If the alarm condition is still present, the ALARM LED will remain on until the PV (process variable) is out of the alarm condition. If manual Reset mode is selected in setup, the ALARM key will also de-energize the alarm relay.
Refer to Setup Procedures section for additional information on setting the appropriate alarms.
TUNE Key
The TUNE key will start an AUTO tune cycle. Heat (or cooling) is automati­cally applied to determine PID values. AUTO tuning must be enabled in the setup mode for this key to function. Refer to the AUTO Tuning section for additional information on this setting.
NOTE: When the TUNE key is pressed, the output is turned full on three
times for a period of time and overshoot of the setpoint will occur. Do not use the AUTO tune feature if this would have an adverse affect on your process.
RUN/STOP Key
Pressing this key when the Temperature Controller is stopped will start the control process and activate the load, if required. Pressing this k e y when the Temperature Controller is r unning will cause it to stop.
