SAFETY PRECAUTIONS

DANGER: There are no user-serviceable parts in this

instrument.Do not remove cover,as high voltages

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 Tempera-

ture Controller R/S (advanced model).

Refer to Figure 1 for a view of the front panel of theTemperature Controller R/

S.Refer to Figures 2 and 3 for a view of the back panels of the 115V 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 perfor-

mance.Thepowerandtypeof heater, thepositioning ofthesensor,theamount

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 consid-

ered in setting up the controller.

One of the most important of these considerations is the heater sizing.A heater

thatis too lowpoweredmaynot beableto raise or even maintain the material at

the desired set point.A heater that is too high powered will not maintain precise

temperature control and may be unsafe. Because of the many system vari-

ables, optimum heater sizing must be determined experimentally; however, an

approximation can be made through a few 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 software algorithm, it adjusts a heater

or cooler by varying the output duty cycle.TheTemperature 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).

TheTemperature 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-

tion.Theunitcanalsobemountedinapanelwith 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 theTempera-

tureController, including various types of temperaturesensors,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)

diskisincludedwiththeR/Scontroller,alongwithaseparateoperator'smanual.

It can be used to set up the controller and perform logging and other func-

tions.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 val-

ues of displayed (blinking) numerals or enable you to scroll through a list

where multiple-choice parameters are offered. The LEFT arrow key allows

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 pa-

rameters of the Temperature Controller. Pressing the MENU key will scroll

through the parameter options, using the arrow keys to change those param-

eters. Refer to the Setup Procedures section for additional information on

each parameter.

SET Key

The SET key allows you 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 display between setpoint and run

time remaining. Refer to the Operation section for additional information on

changing the setpoint.

ALARM Key

TheALARMkeyenablesyoutoacknowledgetemperature control alarm con-

ditions and silence the audible alarm.Pressing the ALARM key 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 automati-

cally 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 key when the

Temperature Controller is running 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 turn on when power is being applied to the heater

output.The green COOL light will turn on when theTemperature 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 Tempera-

ture Controller R/S.

1. Install the unit.

Setup your process.

Plug the Controller power cord to an AC outlet, turn unit on.

Plug the heater (or cooler) into the Controller rear panel and install in

your process.

Connect a sensor to the rear panel (thermocouple, RTD or thermistor)

and install in your process.

Optional installation connections:

Connect a recorder to the recorder contacts on the rear panel.

Connectanexternalalarmtothealarmoutputconnectionontherearpanel.

Connect a serial cable between the Controller RS232 connector and a

PC and follow the instructions for setup in the separate PC program op-

erator manual.

2. Setup the operating parameters. Press MENU and follow the interactive

setup selections. If your setup is the same as the factory set defaults,

this step is not necessary.However, each of the setup options should be

checked for desired or proper setting.

Set sensor type that was connected.

Select temperature scale.

Set alarms, if desired.

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 automati-

cally 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.
