2216L and 2208L Temperature Controllers
Installing and Operating Instructions
The 2216L and 2208L are precision PID temperature controllers
ideal for plastic extrusion machines, ovens, chillers and other
heating and cooling processes. The 2216L is in a 48 x 48mm panel
size (1/16 DIN) and the 2208L in a 48 x 96 panel size (1/8 DIN).
Both controllers have up to three outputs for heating, cooling and
alarms. In addition the 2208L has two contact closure inputs to
select second setpoint and standby mode (all outputs off, except
alarms).
The controller will have been built and configured according to
the ordering code given on page 5. Check the ordering code on
the controller side labels to determine the configuration of your
particular controller.
This controller meets the European directives on safety
and EMC.

ELECTRICAL CONNECTIONS
To install the controller
Please read the safety information on pages 5 & 6 before
proceeding.
Prepare the panel cut-out to the size shown
Insert the controller through the cut-out.
Spring the panel retaining clips into place. Secure the
controller in position by holding it level and pushing both
retaining clips forward.
Unplugging the controller
The controller can be unplugged from its sleeve by easing the
latching ears outwards and pulling it forward out of the sleeve.
When plugging the controller back into its sleeve, ensure that
the latching ears click into place to maintain the IP65 sealing.
Wire Sizes
All electrical connections are made to the
screw terminals at the rear of the
controller. These accept wire sizes from
0.5 to 1.5 mm2 (16 to 22 AWG), and are
protected by a hinged cover to prevent
hands or metal making accidental contact
with live wires. Rear terminal screws
should be tightened to a torque of 0.4 Nm
(3.5 lb in).

AUTOMATIC TUNING
In PID control, the output from the controller is the sum of three
terms: Proportional, Integral and Derivative. These three terms
deliver just the right amount of power to hold the temperature at
setpoint without oscillation. For stable control, the PID values
must be ‘tuned’ to the characteristics of the process being
controlled. In the 2216L and 2208L this is done automatically
using advanced tuning techniques.
Automatic tuning is performed by switching the output of the
controller On and Off to induce an oscillation in the measured
temperature. From the amplitude and period of the oscillation,
the PID values, shown in the table below, are calculated.
Parameter Display Meaning or Function
Proportional
band
0
The bandwidth in °
or °
over which the output
power is proportioned between minimum and
maximum.
Integral time
6O
Determines the time taken by the controller to
remove steady-state error signals.
Derivative
time
6
Determines how strongly the controller will react
to the rate-of-change of temperature.
Low cutback
)
The number of °
or °
below setpoint at which
the controller will cutback the output power to
prevent overshoot on heat up.
High
Cutback
#
The number of °
or °
above setpoint at which
the controller will increase the output power to
prevent undershoot on cool down.
Relative
cool gain
5)D
Only present if cooling has been configured.
Sets the cooling proportional band by dividing the
Pb value by the
5)D
value.
If the process cannot tolerate 100% heating or cooling during
tuning, the power can be restricted by the heating and cooling
limits in the Output list. However, the measured value must
oscillate to some degree for the tuner to determine values.
Tuning is normally performed only once during the initial
commissioning of the process. However, if the process under
control subsequently becomes unstable (because its
characteristics have changed), you can re-tune again at any time.
It is best to start tuning the process from ambient temperature, to
allow the tuner to calculate more accurately the cutback settings.
Heating and Cooling Output Cycle Times
Before commencing a tuning cycle, set the values of
@D#
(heating output cycle time) and
@D
(cooling output cycle
time) in the
/0
(output) list.
For a logic heating output (switching a solid state relay), set
@D#
to
D
sec.
For a relay output, set
@D#
to
D
sec.
For a logic cooling output used to control a solenoid valve, set
@D
to
D
sec.
Tuning procedure
1. Set the setpoint to the value at which you will normally
operate the process.
2. In the ‘
69.
’ list, select ‘
69.
’ and set it to ‘
/.
’
3. Press the Page and Scroll buttons together to return to the
HOME display. The display will flash ‘
69.
’ to indicate
that tuning is in progress.
4. The controller will induce an oscillation in the temperature by
turning the heating on and then off.
5. After two cycles of oscillation the tuning will be completed
and the tuner will switch itself off.
6. The controller will then calculate the tuning parameters and
resume normal control action.
If you want ‘Proportional only’ or ‘P+D’ or ‘P+I’ control, you
should set the ‘
6O
’ or ‘
6
’ parameters to
before
commencing the tuning cycle. The tuner will leave them off and
will not calculate a value for them.
Typical automatic tuning cycle
Calculation of the cutback values
When low cutback or high cutback is set to ‘
97/
’ their values
will be fixed at three times the proportional band, and will not be
altered during automatic tuning. If set to any other value, they
will be calculated as part of the tuning process.
MANUAL TUNING
If for any reason automatic tuning gives unsatisfactory results,
you can manually tune the controller, as follows:
With the process at its normal running temperature:
1. Set Integral Time ‘
6O
’and Derivative Time ‘
6
’ to
.
2. Set High Cutback and Low Cutback, ‘
#
’ and ‘
)
’, to
‘
96/
’
3. Ignore the fact that the temperature may not settle precisely at
the setpoint
4. Reduce the proportional band ‘
0
’ until the temperature just
starts to oscillate. If the temperature is already oscillating,
increase the proportional band until it just stops oscillating.
Allow enough time between each adjustment for the
temperature to stabilise. Make a note of the proportional band
value ‘B’ and the period of oscillation ‘T’.
5. Set the PID parameter values according to the formula below:

P + I + D 1.7xB 0.5xT 0.12xT
Setting the cutback values
The above procedure sets up the parameters for optimum steady
state control. If unacceptable levels of overshoot or undershoot
occur during start-up or for large step changes in temperature,
then manually set the cutback parameters
)
and
#
.
Proceed as follows:
1. Set the low and high cutback settings to 3 x the proportional
band (that is to say,
)
=
#
= 3 x
0
).
2. Note the level of overshoot or undershoot that occurs for
large temperature changes (see the diagrams below).
In example (a) increase
)
by the overshoot value. In example
(b) reduce
)
by the undershoot value.
Example (a) Example (b)
When the temperature approaches the setpoint from above, you
can set
#
in a similar manner.
Manual reset
When the integral term is set to

This parameter sets the
output power when the error signal is zero. This value can be
manually adjusted to remove the steady state error - the function

RE-CONFIGURATION INSTRUCTIONS
The 2216L and 2208L are normally supplied pre-configured to a customer’s requirement using the simple ordering code. The type of
heating, cooling and alarm outputs are defined in the ordering code and cannot be changed by the customer because they are part of the fixed
hardware build. You can, however, change the following software features:
1. The setpoint limits.
2. The temperature display units: °C or °F
3. The type of control: On/Off or PID
4. The type of input sensor
5. The alarm output configuration
6. To configure outputs 1 & 2 to heating and cooling
These instructions tell you how to make these changes.
TO CHANGE THE SETPOINT LIMITS

TO CHANGE OUTPUTS 1 & 2 TO HEATING OR
COOLING
The controller is supplied with output 1 configured as a heating
output, and output 2 configured as a cooling output. It is possible
to re-configure either output for heating or cooling.
It is also possible to configure both outputs for heating (or
cooling) The advantage of this is that one output can be fitted
with a relay and the other with a logic, which gives the user the
choice of using either a logic output or a relay output for the
same function.
Proceed as follows:
TO RECONFIGURE THE ALARM OUTPUT
The alarm output is operated by up to four internal ‘soft’ alarms
i.e. indication only. These alarms can be individually configured
in the

list.
Note: If an alarm is disabled it will not appear in the alarm list in
Operator level.

SAFETY AND EMC INFORMATION
Safety
This controller complies with the European Low Voltage
Directive 73/23/EEC, amended by 93/68/EEC, by the application
of the safety standard EN 61010.
Electromagnetic compatibility
This controller conforms with the essential protection
requirements of the EMC Directive 89/336/EEC, amended by
93/68/EEC, by the application of a Technical Construction File.
This controller satisfies the general requirements of the industrial
environment defined in EN 50081-2 and EN 50082-2.
GENERAL
The information contained in these instructions is subject to
change without notice. While every effort has been made to
ensure the accuracy of the information, Eurotherm Controls shall
not be held liable for errors contained herein.
Unpacking and storage
The packaging should contain the controller with two panel
retaining clips and this instruction leaflet.
If on receipt, the packaging or the controller are damaged, do not
install it but contact your nearest Eurotherm Controls agent.
If the controller is to be stored before use, protect from humidity
and dust in an ambient temperature range of -30oC to +75oC.
SERVICE AND REPAIR
This controller has no user serviceable parts. Contact your
nearest Eurotherm Controls agent for repair.
C
aution:
Charged capacitors
Before removing a controller from its sleeve, switch off the
supply and wait two minutes to allow capacitors to discharge.
Failure to observe this precaution may damage the controller or
cause some discomfort to the user.
Electrostatic discharge precautions
When the controller is removed from its sleeve, it is vulnerable to
damage by electrostatic discharge from someone handling the
controller. To avoid this, before handling the unplugged
controller discharge yourself to ground.
Cleaning
Do not use water or water based products to clean labels or they
will become illegible. Isopropyl alcohol may be used to clean
labels. A mild soap solution may be used to clean other exterior
surfaces of the product.
Safety Symbols
The following safety symbols are used on the controller:
Caution, (refer to the
accompanying documents) Functional earth
(ground) terminal
!
Personnel
Installation must only be carried out by qualified personnel
Enclosure of live parts
To prevent hands or metal tools touching parts that may be
electrically live, the controller must be installed in an enclosure.
Caution:
Live sensors
The logic outputs and the two contact closure inputs are
electrically connected to the sensor input (e.g. thermocouple). In
some installations the temperature sensor may become live. The
controller is designed to operate under these conditions, but you
must ensure that this will not damage other equipment connected
to these inputs and outputs, and that service personnel do not
touch these connections while they are live. With a live sensor,
all cables, connectors and switches for connecting the sensor and
non-isolated inputs and outputs must be mains rated.
Wiring
Wire the controller in accordance with the wiring data given in
these instructions. Take particular care not to connect AC
supplies to the low voltage sensor input or logic outputs. Only
use copper conductors for connections, (except thermocouple).
Ensure that the installation complies with local wiring
regulations.
Power Isolation
The installation must include a power isolating switch or circuit
breaker that disconnects all current carrying conductors. The
device should be mounted in close proximity to the controller,
within easy reach of the operator and marked as the disconnecting
device for the controller.
Earth leakage current
Due to RFI Filtering, there is an earth leakage current of less than
0.5mA. This may affect the design of an installation of multiple
controllers protected by Residual Current Device (RCD), or
Ground Fault Detector (GFD), type circuit breakers.
Voltage rating
The maximum continuous voltage applied between any
connection and ground must not exceed 264Vac.
For the above reason the controller should not be wired to a three
phase supply with an unearthed star connection. Under fault
conditions such a supply could rise above 264Vac with respect to
ground and the product would not be safe.
Conductive pollution
Electrically conductive pollution must be excluded from the
cabinet in which the controller is mounted. For example, carbon
dust is a form of electrically conductive pollution. Where
condensation is likely, for example at low temperatures, include a
thermostatically controlled heater in the cabinet.
Grounding of the temperature sensor shield
In some installations it is common practice to replace the
temperature sensor while the controller is still powered up. Under
these conditions, as additional protection against electric shock,
we recommend that the shield of the temperature sensor is
grounded. Do not rely on grounding through the framework of
the machine.
Over-temperature protection
When designing any control system it is essential to consider
what will happen if any part of the system should fail. In
temperature control applications the primary danger is that the
heating will remain constantly on. This could damage the
product, the machinery being controlled, or even cause a fire.
Reasons why the heating might remain constantly on include:
• the temperature sensor becoming detached from the process
• thermocouple wiring becoming short circuit;
• the controller failing with its heating output constantly on
• an external valve or contactor sticking in the heating state
Where damage or injury is possible, we recommend fitting a
separate over-temperature protection unit, with an independent
temperature sensor, which will isolate the heating circuit.
Please note that the alarm relays within the controller will not
give protection under all failure conditions.

Installation Requirements for EMC
• For general guidance refer to Eurotherm Controls EMC
Installation Guide, HA025464.
• When using relay outputs it may be necessary to fit a filter
suitable for suppressing the conducted emissions. The filter
requirements will depend on the type of load. For typical
applications we recommend Schaffner FN321 or FN612.
Routing of wires
To minimise the pick-up of electrical noise, the sensor input
wiring should be routed away from high-current power cables.
Where it is impractical to do this, use shielded cables with the
shield grounded at both ends.
