INSTRUCTION MANUAL

INSTRUCTION MANUAL
FOR ETR-3200
CONTENTS
Failure of devices, such as the thermocouple-RTD sensor, heater output relay or temperature control can result in
severe damage to a product while in process, melting of the heater or a damaging fire. An over-temperature protec-
tion device must be installed in your process that will remove all power from the heating circuit if the above failure
occurs. We recommend that this device be classified as a safety control and carry FM, U.L. and CSA Listing or
Certification. Failure to install high-limit temperature control protection where a potential hazard exists, could result
in damage to equipment and property, and fatal injury to personnel.
WARNING!
Section 1: INTRODUCTION
This manual contains information for the installation and
operation of the Ogden Model ETR-3200 auto-tuning
micro-processor based controller.
Ease of use is an essential feature on this versatile
controller. Three touch keys are used to select sensor
type, control mode, control parameters, alarm mode,
degrees C/F, auto-manual mode, and to lock the para-
meters from the prevention of unauthorized tampering.
A large 4-digit display shows process values at a
glance. Precise 14 slope sensor linearization, self-diag-
nostic capability, cold junction compensation and 3-
mode PID calculations are automatically executed by
the single chip microprocessor. The wide selection of
parameters, values, sensor types, set points, control
modes, alarm modes, degrees C/F and security codes
are held in a non-volatile memory. Batteries are not
necessary.
The auto-tuning function determines the correct propor-
tional band, rate and reset values to provide accurate
control with minimal overshoot and temperature oscilla-
tion. This is accomplished without the need for expen-
sive and time consuming procedures for set-up of con-
trol parameters. In case of a power failure or temporary
shutdown, the instrument retains the correct parame-
ters. This instrument also has manual override capabili-
ties that allow the operator to bypass the auto-tuning
parameters. Required fine tuning adjustments can then
be made.

Section 3: SPECIFICATIONS

Wiring Precautions:
•Before wiring, verify the label for correct model num-
ber and options. Switch off the power when checking.
•Care must be taken to ensure that maximum voltage
ratings specified in Section 3 on previous page are
not exceeded.
•It is recommended that power to these instruments
be protected by fuses and circuit breakers rated at
the minimum value possible.
•All units should be installed inside a suitably ground-
ed metal enclosure to prevent live parts being acces-
sible to human hands and metal tools.
•All wiring must conform to appropriate standards of
good practice, national and local codes and
regulations. Wiring must be suitable for the maximum
voltage, current, and temperature ratings expected in
the system.
•Take care not to over-tighten the terminal screws.
•Unused control terminals should not be used as
jumper points as they may be internally connected,
causing damage to the unit.
•Verify that the ratings of the output devices and the
inputs as specified on page 3 are not exceeded.
•Electric power in industrial environments contains a
certain amount of noise in the form of transient volt-
ages and spikes. This electrical noise can enter and
adversely affect the operation of microprocessor-
based controls. For this reason we strongly recom-
mend the use of shielded thermocouple extension
wire which connects from the sensor to the controller.
This wire is a twisted-pair construction with foil wrap
and drain wire. The drain wire is to be attached to
earth ground at the sensor end only. We carry both
type J and type K in our stock.
RISK OF ELECTRIC SHOCK - Dangerous and poten-
tially fatal voltages are present when working on this
equipment. Before installation or beginning any trou-
bleshooting procedures, the electric power to this equip-
ment must be disconnected and locked out as described
by OSHA Standards. Units suspected of being faulty
must be removed and returned to Ogden for inspection
and/or repair. They contain no user serviceable compo-
nents.
To help minimize the possibility of fire or shock hazards,
do not expose this instrument to rain or excessive
moisture. This control is not to be used in hazardous
locations as defined in Articles 500 and 505 of the
National Electric Code.
Do not use this instrument in areas subject to
hazardous conditions such as excessive shock,
vibration, dirt, moisture, corrosive gases or oil. The
ambient temperature of the areas should not exceed
the maximum rating specified in Section 3, on previous
page.
Unpacking:
Upon receipt of the shipment inspect the unit for ship-
ping damage. If any damage due to transit is noticed,
report and file a claim with the carrier. Write down the
model number and serial number for future reference
when corresponding with our service center. The serial
number is located on the housing of the control.
Mounting:
Make panel cutout to dimensions shown below. Insert
the controller into the panel cutout. The maximum
panel thickness is 1⁄8" (3.2mm).

Power Wiring:
Connect terminals as shown in Figure 4.3. The power
switch S1 and Fuse F1 are included for illustrative
purpose only. Refer to Figures 4.4, 4.5, 4.6, 4.7 on the
following pages for sample wiring diagrams.
Input Wiring:
Connect the appropriate sensor to terminals 8, 9, 10, 11
or 12 as illustrated in Figure 4.3. Verify that the instru-
ment is selected for the correct sensor and the correct
polarity is observed at both the sensor-end and instru-
ment-end of the cable. Do not run sensor cables in the
same conduit or wiring trough as the power lines,
because the low level signal is noise sensitive.
When wiring the thermocouple, check the thermocouple
and extension wire (compensating cable) to make sure
they conform to the appropriate thermocouple type
specified by the instrument. Extension wires must be
the same alloy and polarity as the thermocouple. The
total lead resistance should not exceed 100 ohms for
accurate measurements. One hundred ohms of lead
resistance will introduce a 1°F (0.5°C ) error.
For wiring 3 wire RTD (Resistance Temperature
Detector) all leads connecting the RTD to the controller
must be the same gauge and material. If the RTD is a
3 wire device, install the two common wires of the RTD
to terminals 10 and 11. If a 2 wire RTD is to be used,
install a jumper between terminals 10 and 11.
See page 21 for instructions to re-range the input to
volts, milli-volts or milli-amps.

NOTE: The use of motor starters in place of
magnetic contactors should be avoided. They
have very large inductive loads that can
damage the controller’s relay.

Output Wiring:
Five different types of output devices can be used from
output one. Relay, Triac, current, voltage and pulsed
voltage provide a variety of control applications, Verify
that the output device is correctly selected to meet your
application requirements and make certain the ratings
of the output devices are not exceeded before wiring
the system.
The external connections depend on what type of
output is installed. Pulsed voltage output is not
isolated from the internal circuits of the instrument.
Sensor Placement
Proper sensor placement can eliminate many problems
in a control system. The probe should be placed so
that it can detect any temperature change with minimal
thermal lag. In a process that requires fairly constant
heat output, the probe should be placed close to the
heater. In processes where the heat demand is
variable, the probe should be closer to the work area.
Some experimenting with probe location is often
required to find this optimum position.
In a liquid process, addition of a stirrer will help to
eliminate thermal lag. Since the thermocouple is
basically a point measuring device, placing more than
one thermocouple in parallel will provide an average
temperature reading and produce better results in most
air heated processes.
Proper sensor type is also a very important factor in
obtaining precise measurements. The sensor must
have the correct temperature range to meet the
process requirements. In special processes the sensor
might have to have different requirements such as
leak-proof, anti-vibration, antiseptic, etc.
Standard thermocouple sensor limits of error are ± 4
degrees F (±2 degrees C) or 0.75% of sensed temper-
ature (half that for special) plus drift caused by improp-
er protection or over-temperature occurance. This
error is far greater than controller error and cannot be
corrected at the sensor except by proper selection and
replacement.
When installation has been completed, the clear protective
film can be removed from the faceplate.

Table 5.5 Engineering Level
The engineering level can be entered at any time by
pressing the keys. This level contains six
parameters for control configuration and options. The
parameters are defined as:
Manual Mode (hand control) –This feature is used if
the sensor fails. The control can now be used as an
on-off proportional timer to control the load until a new
sensor can be installed. The setting for heating or cool-
ing is 0 - 100% of the proportional cycle time.
Peak Process Values –The minimum and maximum
peak values of the process are indicated here.
Calibrate A-D Converter –This parameter is used
during the calibration procedure.
Fail Safe –This defines the status of the outputs if the
sensor fails.
Lock Parameters –Levels 0, 1 or 2 in the operators
level can be locked-out to prevent unauthorized
tampering.
Configuration Level –This feature allows parameters
to change levels (0, 1 or 2) in the operators level. The
purpose of this is to allow only selected parameters to
be adjustable and all the others to be locked-out. For
example, if only the set point is to remain un-locked, all
the other parameters in level 0 can be moved to level 1.
Then lock out level 1 and 2.

Operator Level Parameter Definitions:
PV - Process Value This is the temperature (or other
process variable) as measured at the sensor. This will
indicate a value within the range between the low scale
(Lo.SC) and high scale value (hi.SC). This indication
will read an error code if the temperature (process
variable) goes out of the preset span. Note items 6 and
7 of the troubleshooting guide on page 24 for the error
code descriptions.
SV - Set Point Value This parameter is the desired set
point of the process. It can be adjusted within the
range defined by the low scale (Lo.SC) and high scale
value (hi.SC). The span adjustments can be used to
limit the set point of the controller.
ASP1 - Alarm 1 Set Point Value or Dwell Time This
sets the points at which alarm 1 will energize if A1.SF
(alarm 1 special function) is set for an alarm function.
If A1.SF is selected for the dwell timer function (toon or
toof), then this becomes the timer setting in minutes.
The dwell timer starts counting when the process value
reaches the set point value. Note page 19 for more
information.
rAMP - Ramp Rate This controls the heat-up and
cool-down rate of the process. This setting is in
degrees per minute.
oFSE - Offset Value This parameter is only functional
if the integral time (automatic reset) is set to zero. The
oFSE then functions the same as manual reset to
correct the process temperature to the set point temper-
ature. If the process temperature stabilizes below the
set point, then set a positive amount of oFSE. If the
process temperature stabilizes above the set point, set
a negative amount of oFSE. Wait for the system to
stabilize and make further adjustments as required.
ShiF - Display Shift A value entered here will be
added or subtracted from the process value. This offset
can be used as a correction factor if the sensor does
not read the same temperature as the item being
sensed. Note page 21 for more information.
Pb, Ei and Ed - PID Values Proportional band,
Integral (reset) and Derivative (rate) time constants.
These must be set as close as possible to the process
application requirements. Note page 16 for more infor-
mation.
AhY1 - Hysteresis of Alarm 1 The values entered
here define the deadbands for the alarm. The alarm
will not change state until the temperature is outside of
the deadband.
hySE - Hysteresis of On-Off Control This parameter
defines the deadband when on-off control is used and
PID control has been disabled. For on-off control, set
Pb, Ei and Ed to 0. The output on a relay control will
not change state until the temperature is outside the
deadband. Note page 16 for further information.
Addr - Interface Address For external communica-
tions with a computer or retransmission output setting.
Lo.SC, hi.SC - Low/High Scale Range These
parameters are used to define the range (span) of the
control. These should be set for the requirements and
safety of your process. Refer to Initial operation on
page 16 for further information. If inputs other than
thermocouples or RTDs are required, refer to page 21
for directions.
PL.1, PL.2 - Power Limit These parameters are used
to limit the output percentage of power for heating or
cooling. If the control has relay or pulsed voltage
outputs, then the percentage of “on”time will be
decreased. The actual output levels will be decreased
if the control has linear current (4-20mA) or linear volt-
age outputs.
inPE - Input Type This parameter is used to program
the control to the type of input sensor used.
uniE - Process Units This parameter is used to set
the display in degrees F, C or blank for engineering
units.
rESo - Display Resolution This parameter is used to
place a decimal point in the process and set point
values. A two-place decimal point can only be set if the
uniE adjustment is set to engineering units (PU).
Con.A - Control Action of Output 1 This parameter
selects heating (reverse) or cooling (direct) action for
output 1.
A1.Md - Alarm Mode Selection for Alarm 1 and This
adjustment sets the type of alarm required: deviation
alarm, band alarm or process alarm. Refer to page 19
for more information.
A1.SF - Alarm 1 Special Function This selects
special functions required for use with alarm 1. The
special functions include latching alarms, hold
(inhibited) function or dwell timer function. Refer to
page 19 for more information on alarms.
CyC - Proportional Cycle Time of Output 1 This sets
the proportional cycle time for output 1. This should be
set according to the type of output device used. For
mechanical relays, cycle times of 15 to 20 seconds are
used. For solid-state relays, set this adjustment to 1 or
0. For 4-20mA or other linear outputs set this to 0.
CCyC - Cooling Cycle Time Only used if A1.SF
(alarm 2 special function) has been set for cooling. Use
the same settings as the above paragraph.
C.Pb, d-b Cooling Proportional Band, Cooling
Deadband Only used if A1.SF (alarm 1 special
function) has been set for cooling. Refer to page 21 for
further information on the settings to be used for cooling
output.

Initial Operation:
When the control has been wired you can apply power.
The display should indicate 2220, software version and
LED lamp illumination test. The temperature (or other
process variable) as measured at the sensor should be
indicated by the PV display. The thermocouple is wired
in reverse if the indicated temperature decreases as the
temperature at the thermocouple increases. While
making initial settings to configure the control, the set
point should be lowered to a value (eg. 30°F) to assure
the heaters will not be energized. This will allow time to
make any adjustments of the parameters in the opera-
tors or engineering level.
During this initial set-up, alarm points and other settings
can be made. The low limit and high limit range set-
tings (Lo.SC) and (hi.SC) should be adjusted to your
process. This sets the range (span) of the control. The
set point cannot be adjusted out of this range.
Generally, for plastics processing and packaging, a
span of 0 - 800°F is common. If oils are used, a lower
span such as 0 -300°F should be entered.
When the configuration settings have been made, you
can return to the PV/SV level. Adjust the required
process set point. The red “out”lamp should illuminate,
indicating the heaters have been powered.
Autotuning:
The autotune function “teaches”the controller the main
characteristics of the process. It “learns”by cycling the
output on and off. The process will oscillate around the
set point during autotuning. Note the diagram below:
Adjust the set point to a lower value if overshoot
beyond the normal process value may cause damage.
The results are measured and used to calculate the
optimum PID values. It should not have to be repeated
on the same process. The autotune function starts by
depressing the and keys for 4 seconds; then
release. The process value display will flash on and off
indicating the control is in the autotune mode. No other
adjustments can be made to the system while the con-
trol is autotuning. The control will finish autotuning by
itself and the correct PID values will be entered into the
control’s memory.
Autotuning will not function if the control has been con-
figured from PID to ON-OFF. For electric heating PID is
usually recommended.
Autotuning may not give satisfactory results and hold a
close temperature on all applications. If this occurs,
you can change the PID values manually using the
three charts in Figure 5.2 on the top of the next page
for a guide. It is recommended to change only one
parameter at a time, so the results of that change can
be clearly noted.
Adjusting PID Parameters:
The PID parameters can be reviewed by operating the
scroll key and noting whether the values are reasonable
or not. Examine the controller’s result. Modify the PID
values until the control quality is acceptable.
ON-OFF Control:
On-off control action is recommended when continuous
cycling of the load cannot be used. Examples are
mechanical solenoids, large contactors and valves. For
on-off control, set the following parameters to zero:
proportional band; integral; derivative and offset (oFSE).
The hysteresis (hySE) adjustment is now used to set
the deadband. The larger the hysteresis is set, the
larger the deadband will be. A large deadband will
cause the contactor (or other device) to switch less
often, but the process will oscillate farther from the set
point. This setting is measured in degrees.

The proportional band ( ) adjustment is a percentage of
SPAN or RANGE value.
Integral action (automatic reset) corrects for offset (load
error) for load variations. Reset wind-up inhibition prevents
integral action from occurring outside of the proportional
band. Software antisaturation minimizes process oscilla-
tions when the load changes.
Derivative action is adjusted to match the response time of
the process and to compensate the integral action.
Correct adjustment provides power output compensation
for process load variations. It also minimizes overshoot
and oscillations at start up or in large process upsets.
Refer to Figure 5.1 for additional adjustment instructions.
Manual Tuning Procedures:
For some systems it is difficult to execute automatic tuning
or the automatic tuning results are not satisfactory. The
following steps can then be used for initial tuning of a
three-mode control:
Step 1: Adjust the integral and derivative values to 0. This
inhibits the rate and reset action.
Step 2: Set an arbitrary value of proportional band and
monitor the control results.
Step 3: If the original setting introduces a large process
oscillation then gradually increase the proportional
band until the oscillation disappears.
Step 4: If the original setting does not introduce process
oscillations then gradually decrease the propor-
tional band until steady cycling is observed.
Record this important proportional band percent-
age (Pc).
Step 5: Time the period of steady cycling. Record this crit-
ical period Tc. The PID parameters are deter-
mined as:

PID Control
For various applications the controller can be used as P
control only (set integral = 0, derivative = 0); PI control (set
derivative = 0), PD control (set integral = 0), and PID
control.
Figure 5.4, on page 17, represents the response of a
typical control system using various modes of control.
1.) P control results in a response showing a deviation
(offset), a high overshoot and a moderate period of
oscillation. In addition, a significant length of time is
required before the system ceases to oscillate.
2.) PI control has no offset, but elimination of offset comes
at the expense of higher overshoot, larger period of
oscillation and a longer time required for oscillations to
cease compared with other modes of control.
3.) PD control generally brings the system to steady state
in the shortest time with the least oscillation. However,
it still has offset.
4.) PID control is essentially a compromise between the
advantages of PI and PD control. Offset is eliminated
by the integral action. The derivative action serves to
lower offshoot and to eliminate some of the oscillations
realized with PI control.
Ramp and Soak Function:
The ETR-3200 can be programmed as a two segment
ramp and soak control. The ramp rate, in degrees per
minute, is determined by the ““setting. The soak
function is accomplished by configuring alarm 1 relay as a
timer. The heater (or contactor coil) must be wired in
series through the alarm 1 relay and the “out 1”relay.
Refer to wiring diagram figure 4.8 on page 8. To use this
feature, set A1.SF (alarm 1 special function) to . Set
the soak period at ASP1 (alarm 1 set point). The alarm
relay will be closed at start-up. It will remain closed until
the process temperature has remained at the set point
temperature for the time period (minutes) set in ASP1.
Note the following example: The ramp rate is set to 20
(degrees per minute), A1.SF is set to and ASP1 to
30 (minutes). When the control is powered, the process
will climb at 20 degrees per minute to the set point of
475°F. Once the set point temperature has been reached,
the soak timer begins counting. After a time period of 30
minutes has elapsed, the alarm relay 1 will open and the
process temperature falls at an uncontrolled rate. This
process will repeat every time power has been switched
off and on to the controller. Note diagram 1 below.
Single Event (Dwell) Function:
The single event (dwell) function may be used to control
external devices such as lights, bells or locks. It could
also be used to alert the operator when a guaranteed
soak time has been reached. To use this feature, set
ASP1 (alarm 1 set point) to the time period (in minutes) of
the timer. Set A1.SF (alarm 1 special function) to .
The alarm relay will now operate as a timer. The alarm
relay will be open at start-up. Once the set point tempera-
ture has been reached and the time period set in ASP1
has elapsed, the alarm relay will close. This relay will
remain closed until power to the control has been discon-
nected. The cycle will repeat each time the control has
been energized. Other features such as ramp rate can
also be used. Note diagram 2 below. The set point is
175°F and the dwell time has been set to 30 minutes.
