Wiring
Dimensions
IMPORTANT: All electrical wiring connections should be made
only by trained personnel, and in strict accordance with the
National Electrical Code and local regulations.
Figure 2. Case Dimensions
The Series CN8200 controller has built-in circuitry to reduce
the effects of electrical noise (RFI) from various sources.
However, power and signal wires should always be kept
separate. We recommend separating connecting wires into
bundles: power; signal; alarms; and outputs. These bundles
should then be routed through individual conduits. Shielded
sensor cables should always be terminated at one end only.
Prior to mounting the Series CN8200 in your panel, make
sure that the cutout opening is of the right size, 1.771" x
1.771" (45 mm x 45 mm), and deburred to enable a smooth
fit. A minimum of 4" (100 mm) of depth behind the panel is
required.
Mounting
When properly installed
through a NEMA
enclosure, the integrity
of the enclosure will be
maintained and will
remain “Watertight.”
If additional RFI attenuation is required, noise suppression
devices such as an R.C. snubber at the external noise source
may be used.
Figure 3. Series CN8200 Mechanical Components
Insert the Series CN8200 through the front panel cutout and
slide the mounting collar back onto the unit from behind the
panel. Push the mounting collar up tight to the back of the
mounting panel.

Make sure that you are using the appropriate thermocouple
and extension wire. Connect the negative lead (generally
colored red in ISA-type thermocouples) to contact #9;
connect the positive lead to contact #10. Extension wires
must be the same polarity as the thermocouple.

Figure 6. RTD Wiring
The Series CN8200 accepts input from 2- or 3-wire, 100 ohm
platinum resistance temperature detectors (RTDs). Connect
2-wire RTDs to contacts #9 and #10, with a jumper across
contacts #8 and #10. Keep leads short and use heavy gauge
copper extension wire, if necessary, to minimize lead
resistance. For long runs, 3-wire RTDs should be used.
The Series CN8200 power supply accepts 100 to 250 Vac and
100 to 250 Vdc line power without any switch settings or
polarity considerations. All connections should be made in
accordance with the National Electrical Code and local
regulations, using only NEC Class 1 wiring for all power
terminals.
It is advisable, but not necessary, to fuse one leg of the
incoming power line, contact #11, with a 2AG, 0.5 amp rated
fuse. It is recommended that instrument power and load
power be fused independently.

Output Types
The Type “R” output
is a mechanical device
and subject to wear.
To extend the life of
the relay, set the Cycle
Time for the relay
output to the longest
duration that still
affords good control.
When you ordered your Series CN8200 controller specific
output types were specified, designated as “R”, “DC”, “T”,
“F”, or “FH”. You also had the option of configuring your
controller with either one or two output actions. The numbers
below are suggested for most typical applications.

Note: The damping parameter specifies how aggressively the
controller performs its autotuning. The “Normal” setting is a
compromise between the fast recovery and overshoot. The
“Low” setting provides faster recovery, but with the possibility
of overshoot; the “High” setting a slower recovery, but with
minimum or no overshoot.
Recipe (Ramp/

Single Setpoint Ramp Time
This selection will cause the controller to ‘ramp’ the
process from the starting point (current process value)
to the setpoint in the time specified. This ramp will take
place at startup when selected from the Ramp/Soak menu.
The setpoint must be at least ±0.2% of sensor span for the
ramp to be employed.
Multi-Step Ramp
This selection will enable the programming of a recipe (make all
ramp/soak recipe variables visible). Recipes can be resumed on
startup if interrupted by a power failure or initiated, held, and
terminated from the front panel via the Mode Menu or with the
logic input option (initiate and held/resumed only).
Holdback Band
Specifies the maximum number of degrees above or below
setpoint that the process can be for the segment timer to keep
going. The timer will hold while the process settles back into the
band and then continue. If this feature is not desired, this
parameter should be set to
which will disable it.
Termination State
This parameter determines what the control will do at the
completion of a recipe. Last Setpoint refers to the last
temperature specified in the ramp/soak recipe. Default
Setpoint refers to the standard setpoint which was in effect prior
to recipe initiation.
Recycle Number
Specifies the number of times after the first time that the recipe
is run before the program terminates.

Power Fail Resume
Setting this parameter to On will cause the control to resume
a recipe which was active when a power failure occurred. The
recipe will resume at the start of the last active ramp or soak
segment.

Autotuning
In order for the controller
to autotune properly, the
setpoint value must be at
least 1% of span above or
below the initial process
value. Make sure that the
Setpoint Target Time
parameter is set to OFF.
Tuning accuracy increases
as the spread between
ambient and setpoint
value increases.
Tuning should be
performed with system
in equilibrium (no latent
energy remaining).
Autotuning
To place the controller in Autotune mode:
1) Configure the controller by following the directions for
Initial Setup Sequence through Step 3 on page 16. Set
damping parameter. (See page 26.)
2) If the controller is not already in Standby mode, place it
in Standby now as follows. Press and hold the
Mode/Enter
key for three seconds. Display will
indicate your current operating mode. Press the Raise
key or Lower
key to select Standby. Press Mode key
again and the display will alternate between
and
the process value. This will deactivate all outputs.
Autotuning Procedure Diagram
3) If Setpoint Value has not been entered, adjust setpoint
now by using the Raise or Lower key to set the desired
setpoint.
Note: Keep in mind that the setpoint value must be at least
1% of span above or below the initial setpoint, and that the
process value must be stable prior to initiating the tune.
4) Wait for process to stabilize before proceeding, e.g., in
the case of a heating and cooling process, return to
ambient temperature.
Current
Mode
5) Initiate Autotuning. Press and hold the Mode/Enter key
again for three seconds, then press the Raise or Lower
key repeatedly until
appears. Finally, press the
Mode/Enter key again. The display will alternately indicate
and process value as the controller “learns” the
proper proportional band, derivative, and integral values
for the process. If unacceptable overshoot occurs on
restart, shut down the process and increase the damping
setting. If sluggish response is observed, shut down the
process and decrease the damping setting.

If a tune error condition occurs, the upper display will toggle
between
and a numeric error code for three seconds
before the tune process terminates. The controller will then
automatically go into Standby mode when a tuning error
occurs. Possible error codes are:

Manual Tuning Procedure
(Zeigler-Nichols PID Method)
This tuning method may be used for non-temperature control
processes or if the spread between ambient temperature and
process operating temperature is small. For best results, the
use of a recording device is required when tuning with this
method.

5) Adjust setpoint to the desired value with the Raise/Lower
keys.
6) Press the Mode/Enter
key for four seconds, the Raise
key twice
, and the Mode/Enter key again to
return the controller to normal operation.
7) While monitoring the recording device, decrease the
proportional band value by repeatedly halving the value
until a small, sustained temperature oscillation is
observed. Measure the period of one cycle of oscillation
(“T” on the diagram below).
T
8) Divide the period of oscillation (T) by eight. The resulting
number is the correct Derivative
time in seconds.
Multiply this number by four. This is the correct Integral
time
in seconds.
9) Multiply the bandwidth value obtained in Step 7 by 1.66
and enter this as the new proportional band value.

Glossary
Alarm Delay - the time delay between the detection of the alarm condition and
the initiation and indication of the output action.
Alarm Inhibit - prevents low setpoint alarm activation during cold startup
applications.
Bias - allows the operator to compensate for any difference between sensor
temperature and the point to be measured. The process display and setpoint
will be offset by the value entered in the Bias parameter in the input menu. Ex:
Desired temperature is 150 degrees. Sensor is adjacent to heater and reads 50
degrees higher than the actual process temperature. Enter bias of -50. Enter
setpoint of 150. Process will display 150 even though sensor will be
measuring 200 degrees.
Blanking - controls the time the setpoint value display remains on. After the set
time, the setpoint value display turns off. Pressing any button causes the
setpoint value display to reappear for the selected time interval.
Cycle Time - The period of time in which the controller’s output completes an
on-off cycle (Proportional Output Type only).
Example: Output type = Mechanical relay
Cycle time = 10 seconds
Output power = 50%
Controller output = 5 seconds closed,
5 seconds open
Deadband - In On/Off temperature control, it is the band above or below the
setpoint where there is no output action. It has the effect of moving the
apparent setpoint.
Derivative (rate) - Adjusts the controller gain quickly in response to load
changes.
Failsafe State - designates the percentage of power output that the controller
defaults to after it detects a loop break condition and after the loop break time
has elapsed.
Filter (in Display menu) - changes the filtering speed for the process value
display only. It does not affect control. This parameter is mainly used to slow
down the flickering of the display when the decimal position chosen is greater
than zero.
Filtering (in Input menu) - sets the time period over which the process value is
averaged.
Highest Reading - records the highest process value read by the controller. It
may be reset to zero by using the Raise or Lower arrow keys.
Hysteresis - In On/Off temperature control, hysteresis represents the band
where the output changes state from deactivated to activated. It prevents
chattering around the setpoint and prevents rapid output cycling.
Integral (automatic reset) - slowly adjusts the position of the Proportional
Band (range of power output) to eliminate offset error.
Loop Break - a condition where the input is not changing or responding
properly to the output action. This could be caused by a thermocouple or input
failure, or a heater or load failure.
42
Glossary
Loop Break Time - the time interval from when the controller detects a loop
break condition and the initiation of the failsafe state.
Lowest Reading - records the lowest process value read by the controller. May
be reset to zero by using the Raise or Lower arrow keys.
Lower Setpoint Limit - prohibits users from adjusting the setpoint lower than
the selected value.
Manual Reset - an adjustment that moves the Proportional Band up or down by
a fixed percentage so that more or less power is applied at setpoint. It is used
to eliminate offset error.
On/Off Output Type - In a heating application, the controller applies 100%
output power if the process temperature is below the setpoint and 0% at the
setpoint. For a cooling application, the controller applies 100% output power if
the process temperature is above the setpoint and 0% output power at the
setpoint. There are only two output states: fully on and fully off.
Applications for On/Off Control:
1. When temperature oscillation is acceptable.
2. When constant cycling of mechanical devices is
prohibited (Compressors, Blowers, etc.)
3. Under-powered processes
Output Low Limit % - Prohibits the controller’s output from going
below the specified percentage.
Output High Limit % - Prohibits the controller’s output from going above the
specified percentage.
PID Output Type (Proportional - Integral - Derivative) - The controller
modulates output power by adjusting the output power percentage within a
proportional band. Power is proportionally reduced as the process temperature
gets closer to the setpoint temperature. PID control helps reduce overshoot on
start-up, enhances stability, and compensates for process lag. The PID
parameters are automatically calculated for a particular application during the
autotune procedure.
Applications for PID Control:
1. Where process temperature lags exist
2. When load changes are present
3. When overshoot is prohibited
4. When very accurate control is required
Proportional Band - the band (expressed in degrees of temperature) in which
the controller modulates its power percentage.
Temperature Lag - The product of thermal resistance and thermal capacity.
Also defined as delay of the transmission of heat from the controlled element
to the sensor caused by thermal mass of the process material and/or process
container, or the distance between the control element and the sensor.
Upper Setpoint Limit - prohibits users from adjusting the setpoint higher than
the selected value.

Quick Setup Instructions - Series CN8200 Temperature Controller
Experienced users, already familiar with the Series CN8200, and using the
controller with PID outputs, may follow these condensed instructions to
autotune the controller and get started quickly once the instrument is properly
mounted and wired, and the Security Level is set to
. Once setup is
complete, we recommend changing the Security Level back to the most
restrictive level suitable for your application.
These quick setup instructions are not meant as a substitute for reading the full
instruction manual supplied with the controller. Please be sure to read through the manual for specific
details of operation and, most importantly, for safety precautions. If you have any questions, or
experience problems with setting up your controller, consult the full instruction manual first and, if
