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).
Refer to Figure 1 for a vie w of the front panel of the Temperature Controller R/
S. Refer to Figures 2 and 3 for a view of the back panels of the 115 V or 230
V versions.

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.

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.

HEAT, COOL, TUNE LED Annunciators
These three indicators will light to indicate Temperature Controller functions.
The green HEAT light will tur n on when power is being applied to the heater
output. The g reen COOL light will turn on when the Temperature Controller is in
the cooling mode and power is applied to the cooler output. The yellow TUNE
light will turn on when the Temperature Controller is in the AUTO tuning mode .
How to Use this Product
Here is a summary of the steps required to setup and operate the Temperature Controller R/S.
1. Install the unit.

Calibrate system, if better accuracy is desired.
Set safety stops (over temperature and loop break).
Select control action and mode desired (PID, on/off or Ramp/Soak).
Setup recorder output temperatures, if a recorder is connected.
Set baud rate for serial connection, if a PC is connected.
3. Set the run temperature and begin controlling.
Press the SET key and enter the desired setpoint temperature.
Press TUNE if autotune is selected in setup and you want to automatically determine the PID settings.
Press the RUN/STOP key to begin temperature control.
The setpoint (SP) temperature and the actual temperature (or process
variable, PV) are displayed.
Press ALARM to acknowledge an alarm condition.
