INTRODUCTION
This manual provides information for installing and operating the Temperature Controller R/S (advanced model).
Refer to Figure 1 f or a view 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 po wer 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 e ven 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 variables, optimum heater sizing m ust be determined experimentally; however, an
approximation can be made through a f e 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 software 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-
Page 8

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 separ ate operator's manual.
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.

Process Alarms
Process alarms are absolute values. These values remain the same no matter what the setpoint temperature is set to. For example: if the operator sets
an alarm to trigger at 60 degrees Celsius and the SP (setpoint) temperature
is set at 55 degrees Celsius, the alarm will trigger at 60 degrees. If the operator resets the SP temperature to 57 degrees, then the process alarm value
will stay at the already set 60 degrees.
There are three types of process alarms: PROCESS HI, PR OCESS LO, and
PROCESS HILO. Refer to the following paragraphs for more information.
Process HI
1. Process HI is a fixed value and will not change if the SP temperature
value is changed. It activates the alarm when the PV temperature exceeds the set alarm temperature. Refer to Figure 16. If the Control Action
is set to COOL and the PV temperature exceeds the alarm temperature
when the RUN key is pressed, the alarm will not be activated. The PV
temperature must first fall below the alar m temperature before the high
alarm is enabled. This allows for normal system startup without activating the alarm.

below the alarm temperature. Refer to Figure 18. If the Control Action is
set to HEAT and the PV temperature is below the alarm temperature
when the RUN key is pressed, the alarm will not be activated. The PV
temperature must first rise above the alarm setpoint before the lo w alarm
is enabled. This allows for nor mal system star tup without activating the
alarm.

Process HILO
1. Process HILO is a fixed value (a fix ed high and a fixed lo w alarm setpoint)
and will not change if the SP temperature value is changed. The purpose
for process HILO is to set the fixed HI and LO value at which to trigger
the alarm relay. Ref er to Figure 20. Refer to the Process HI and Process

Deviation Alarms
Deviation alarms are offset values relative to the setpoint (SP). The values
change with the SP temperature setting. F or e xample: if an operator sets the
deviation HI alarm to 10 degrees F ahrenheit and the SP temperature is at 50
degrees Fahrenheit, the alarm will trigger when the PV reaches 60 degrees
Fahrenheit. If the operator then changes the previously set SP temperature
to 55 degrees Fahrenheit, then the alar m will tr igger at 65 degrees Fahrenheit. The 10-degree Fahrenheit difference stays the same.
There are four possible deviation alar ms settings: DEVIATION LO, DEVIATION HI, DEVIATION HILO, and DEVIATION BAND. Refer to the following
paragraphs.
Page 20

Deviation LO
Deviation LO adjusts the alarm value as the SP temperature v alue is adjusted.
Whatever value deviation LO is set at, it will remain the same until changed.
Refer to Figure 22.

DEVIATION LO
FIGURE 22. DEVIATION LO SCREEN
For example: if the Deviation LO value is set for 10 degrees Fahrenheit and
the SP temperature is set for 50 degrees Fahrenheit, the alarm will trigger at
40 degrees F ahrenheit. If the SP temper ature value is changed to 45 degrees
F ahrenheit, the Deviation LO will trigger the alarm at 35 degrees F ahrenheit.
If the Control Action is set to HEAT and the alarm condition exists when the
RUN key is pressed, the alarm will not be activated. The PV temperature
must first rise above the alarm setpoint before the alarm is enabled. This
allows for normal system startup without activating the alarm.
Select the DEVIATION - LO screen by pressing the MENU k ey. The f ollowing
screen will appear (refer to Figure 23). Move the cursor to the left using the
LEFT arrow key. When the setting is correct, press the MENU key to enter
that setting and to move the program to the alarm hysteresis screen.

degrees Fahrenheit. If the SP temperature value is changed to 55 degrees
Fahrenheit, the de viation HI will not trigger the alarm until it reaches 65 degrees
Fahrenheit. If the Control Action is set for COOL and the alarm condition exists
when the RUN key is pressed, the alarm will not be activated. The PV temperature must first fall below the alarm setpoint to enable the high alarm. This allows
for normal system startup without activating the alarm.

alarm condition. Alarm hysteresis prevents actuation of nuisance, or recurrent, alarms. Hysteresis is either added or subtracted to the alarm
point, depending on whether a HI or LO ALARM has been set.
For example: If hysteresis is set at 1 degree and the HI alarm has been
set to trigger when the temperature reaches 100 degrees F ahrenheit, the
alarm will trigger at 100 degrees. As soon as the temperature drops below 99 degrees the alarm condition will terminate.
2. Set the hysteresis by using the arrow keys.
