Safety and EMC
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Power down all equipment before starting the installation, removal, wiring,
maintenance or inspection of the product.
Always use properly rated voltage sensing device to confirm the power is off.
Power line and output circuits must be wired and fused in compliance with local and
national regulatory requirements for the rated current and voltage of the particular
equipment. i.e. UK, the latest IEE wiring regulations, (BS7671), and USA, NEC
Class 1 wiring methods.
Failure to follow these instructions will result in death or serious injury.
Reasonable use and responsibility
The safety of any system incorporating this product is the responsibility of the
assembler/installer of the system.
The information contained in this manual is subject to change without notice. While
every effort has been made to ensure the accuracy of the information, your supplier
shall not be held liable for errors contained herein.
This controller is intended for industrial temperature and process control applications
when it will meet the requirements of the European Directives on Safety and EMC.
Use in other applications, or failure to observe the installation instructions of this
manual may impair safety or EMC. The installer must ensure the safety and EMC of
any particular installation.
Failure to use approved software/hardware with our hardware products may result in
injury, harm, or improper operating results.
11 HA032842ENG Issue 2

Safety and EMC EPC3016, EPC3008, EPC3004
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Do not use the product for critical control or protection applications where human or
equipment safety relies on the operation of the control circuit.
This product must be installed, connected and used in compliance with prevailing
standards and/or installation regulations. If this product is used in a manner not specified
by the manufacturer, the protection provided by the product may be impaired.
Personnel
Electrical equipment must be installed, operated, serviced and maintained only by qualified
personnel.
Enclosure of Live Parts
To help prevent hands or metal tools touching parts that may be electrically live, the
controller must be installed in an enclosure.
Live sensors
The controller is designed to operate if the temperature sensor is connected directly to an
electrical heating element. However, you must ensure that service personnel do not touch
connections to these inputs while they are live. With a live sensor, all cables, connectors
and switches for connecting the sensor must be mains rated for use in 230Vac +15%
CATII.
Charged capacitors
Before removing an instrument from its sleeve, disconnect the supply and wait at least two
minutes to allow capacitors to discharge. Avoid touching the exposed electronics of the
instrument when withdrawing it from the sleeve.
Voltage rating.
The maximum continuous voltage applied between any of the following terminals must not
exceed 230Vac +15%:
• relay output to logic, dc or sensor connections
• any connection to a protective earth ground
Power Isolation
The installation must include a power isolating switch or circuit breaker. This device must
be in close proximity of the controller, within easy reach of the operator and marked as the
disconnecting device for the instrument.
Overcurrent protection
The power supply to the system must be fused appropriately to protect the cabling to the
controller.
Conductive pollution
Electrically conductive pollution must be excluded from the enclosure in which the
controller is installed. For example, carbon dust is a form of electrically conductive
pollution. To secure a suitable atmosphere in conditions of conductive pollution, fit an air
filter to the air intake of the enclosure. Where condensation is likely, for example at low
temperatures, include a thermostatically controlled heater in the enclosure. This product
has been designed to conform to EN61010 installation category II, pollution degree 2.
These are defined as follows:
Pollution Degree 2. Normally only non-conductive pollution occurs. Occasionally,
however, a temporary conductivity caused by condensation must be expected.
Installation Category II (CAT II). The rated impulse voltage for equipment on nominal
230V supply is 2500V.
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.
Failure to follow these instructions will result in death or serious injury.

WARNING
UNINTENDED EQUIPMENT OPERATION
Safety and EMC
Safety and EMC protection can be seriously impaired if the unit is not used in the
manner specified. The installer must ensure the safety and EMC of the installation.
This instrument complies with the European Low Voltage Directive 2014/35/EU, by
the application of the safety standard EN 61010.
Electrostatic discharge precautions.
Always observe all electrostatic precautions before handling the unit. When the
controller is removed from its sleeve, some of the exposed electronic components
are vulnerable to damage by electrostatic discharge from someone directly handling
the controller.
Service and repair.

Electromagnetic compatibility.
This instrument conforms with the essential protection requirements of the EMC
Directive 2014/35/EU. It satisfies the general requirements of the industrial
environment defined in EN 61326.
Installation requirements for EMC.
To comply with the European EMC directive certain installation precautions are
necessary:
• General guidance. Refer to EMC Installation Guide, Part no. HA025464.
• Relay outputs. It may be necessary to fit a suitable filter to suppress conducted
emissions.
• Table top installation. If using a standard power socket, compliance with
commercial and light industrial emissions standard is required. To comply with
conducted emissions standard, a suitable mains filter must be installed.
Wiring.
It is important to connect the controller in accordance with the wiring data given in
this guide. Take particular care not to connect AC supplies to the low voltage sensor
input or other low level inputs and outputs. Only use copper conductors for
connections (except thermocouple inputs) and ensure that the wiring of installations
complies with all local wiring regulations. For example, in the UK use the latest
version of the IEE wiring regulations, (BS7671). In the USA use NEC Class 1 wiring
methods.
Routing of wires.
To minimise the pick-up of electrical noise, the low voltage DC connections and 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. In general
keep cable lengths to a minimum.
Hazard of Incorrect Configuration.
Incorrect configuration can result in damage to the process and/or personal injury
and must be carried out by a competent person authorised to do so. It is the
responsibility of the person commissioning the controller to ensure the configuration
is correct.
Loss of Communications
If the output is not wired, but written to by communications, it will continue to be
controlled by the communications messages. In this case take care to allow for the
loss of communications
Failure to follow these instructions can result in death, serious injury or
equipment damage.

WARNING
EQUIPMENT AND PERSONNEL PROTECTION
• The designer of any control scheme must consider the potential failure modes
which could occur and provide a means to achieve a safe state during and after
a failure.
• Independent or redundant devices must be provided for critical control
functions.
• The control scheme may include communication links. Consideration must be
given to the implications of unanticipated transmission delays or failures of the
link.
• Each implementation of this equipment must be individually and thoroughly
tested for its intended operation before being placed into service.
Failure to follow these instructions can result in death, serious injury or
equipment damage.
WARNING
OVER TEMPERATURE PROTECTION
In temperature control applications a danger could be present if the heating
remains constantly on. Apart from potentially spoiling the end product, this could
damage the process machinery being controlled, or cause a fire hazard. Consider
the following examples:
• a temperature sensor becoming detached from the process
• thermocouple wiring becoming short circuit
• the controller operating with its heating output constantly on
• an external valve or contactor sticking in the heating condition
• the controller setpoint set too high.
The alarm relays within the controller will not give over-temperature protection
under all conditions. The installer must, therefore, fit a separate over-temperature
protection device, with an independent temperature sensor, to isolate the heating
circuit should an over-temperature condition occur.
Failure to follow these instructions can result in death, serious injury or
equipment damage.

Cybersecurity
What’s in this Chapter
This chapter outlines some good practice approaches to cybersecurity as they relate
to use of EPC3000-series controllers, and draws attention to several
EPC3000-series features that could assist in implementing robust cybersecurity.
Introduction
When utilising Eurotherm EPC3000-series controllers in an industrial environment, it
is important to take ‘cybersecurity’ into consideration: in other words, the installation’s
design should aim to prevent unauthorised and malicious access. This includes both
physical access (for instance via the EPC3000 front panel or HMI screens), and
electronic access (via network connections and digital communications).
Secure network topologies and good practices
Overall design of a site network is outside the scope of this manual. The
Cybersecurity Good Practices Guide, Part Number HA032968 provides an overview
of principles to consider. This is available from www.eurotherm.co.uk.
Typically, an industrial controller such as the EPC3000 together with any associated
HMI screens and controlled devices should not be placed on a network with direct
access to the public Internet. Rather, good practise involves locating the devices on a
firewalled network segment, separated from the public Internet by a so-called
‘demilitarized zone’ (DMZ).
Security Features
The sections below draw attention to some of the cybersecurity features of
EPC3000-series controllers.
Principle of Secure by Default
Some of the digital communication features on the EPC3000-series can provide
greater convenience and ease-of-use (particularly in regards to initial configuration),
but also can potentially make the controller more vulnerable. For this reason, these
features are turned off by default:
Comms ports and channels disabled by default
EPC3000-series controllers support a variety of digital communications (see
"EPC3016 Options" on page 34, "EPC3008 and EPC3004 Options" on page 35 and
"Communications List (COmm)" on page 140). By default, the ports and channels
associated with any digital comms are closed to traffic, unless that method of
communication is explicitly selected using the parameters in the mAIN menu (see
"Main Sub List (mAIN)" on page 141).
16 HA032842ENG Issue 2
Page 17
Cybersecurity EPC3016, EPC3008, EPC3004
The only exception to this principle is for the configuration port on the left side face of
the controller. This is a serial port, used with a bespoke Eurotherm-supplied ‘config
clip’ cable, for communication with Eurotherm’s iTools software and for performing
firmware upgrades (see "Using the Configuration Clip" on page 182). Whilst this
serial port is always enabled, it is physically inaccessible when the controller is
installed and mounted in the normal way. It can only be accessed by removing the
controller from its mounting, thus disconnecting all other I/O connections.
Bonjour auto-discovery disabled by default
Ethernet connectivity is available as an option on EPC3000-series controllers (see
"EPC3016 Options" on page 34 and "Auto discovery" on page 274"Auto discovery"
on page 274), including the Bonjour service discovery protocol (see "Bonjour" on
page 274). Bonjour enables the controller to be automatically discovered by other
devices on the network without the need for manual intervention. However, for
cybersecurity reasons, it is disabled by default, as it could be exploited by a malicious
user to gain access to the controller.
See also section "Auto discovery" on page 274.
HMI Access Level / Comms Config Mode
As described in "Operator Levels" on page 69, EPC3000-series controllers feature
tiered, passcode-restricted operator levels, so that available functions and
parameters can be restricted to appropriate personnel.
Level 1 functions are the only ones that do not require passcode access, and are
typically appropriate for routine operator use. The controller powers up in this level.
All other levels are passcode-restricted. Level 2 makes an extended set of
operational parameters available, typically intended for use by a supervisor. Level 3
parameters would typically be set when an authorised person was commissioning the
device for use in a particular installation. Config level allows access to all the
controller’s parameters. Passcode-restricted access to these parameters is also
possible over digital communications, using Eurotherm’s iTools software
("Configuration Using iTools" on page 181),
At config level, it is also possible to customise the other levels from their defaults,
restricting certain parameters to only be available at a higher level, or making certain
parameters available at lower levels. In particular, you can configure the availability of
setpoint program control parameters such as start/stop, auto/manual, setpoint,
manual output, program edit and program run (see "Configuration Sub-List" on
page 109).
HMI Passcodes
When entering passcodes via the HMI, the following features help protect against
unauthorised access:
• Each digit is obscured (replaced with an underscore character) after entry, to
help protect against an unauthorized person seeing the passcode as it’s typed in.
• Passcode entry is locked after three invalid attempts. The time it stays locked for
is configurable (see "Security Sub-List (SEC)" on page 171). This helps protect
against “brute force” attempts to guess the passcode.
17 HA032842ENG Issue 2
Page 18
Cybersecurity EPC3016, EPC3008, EPC3004
• The controller records the number of successful and unsuccessful login attempts
for each level of passcode (see "Diagnostics Sub-list" on page 123). Regular
auditing of these diagnostics is recommended, as a means to help detect
unauthorized access to the controller.
Comms Config Level Passcode
The passcode for Config Level access via iTools has the following features to help
protect against unauthorised access (see "Instrument List" on page 186 for more
details):
• If the passcode is not changed from its initial default value, or is changed to a
password that was used previously, an alert message is displayed.
• By default, each passcode expires after 90 days, and needs to be changed. This
expiry period is configurable.
• Passcode entry is locked after three invalid attempts. The time it stays locked for
is configurable. This helps protect against “brute force” attempts to guess the
passcode.
• The controller records the number of successful and unsuccessful login attempts
for each level of passcode. Regular auditing of these diagnostics is
recommended, as a means to help detect unauthorized access to the controller.
Ethernet security features
Ethernet connectivity is available as an option on EPC3000-series controllers (see
"EPC3016 Options" on page 34 and "EPC3008 and EPC3004 Options" on page 35).
The following security features are specific to Ethernet:
Ethernet rate protection
One form of cyberattack is to try to make a controller process so much Ethernet traffic
that this drains systems resources and useful control is compromised. For this
reason, the EP3000-series includes an Ethernet rate protection algorithm, which will
detect excessive network activity and help to ensure the controller’s resources are
prioritized on the control strategy rather than the Ethernet. If this algorithm is
activated, the rate protection diagnostic parameter will be set to ON (see
"Network Sub List (nWrk)" on page 142).
Broadcast Storm protection
A ‘broadcast storm’ is a condition which may be created by cyberattack: spurious
network messages are sent to devices which cause them to respond with further
network messages, in a chain reaction that escalates until the network is unable to
transport normal traffic. The EPC3000-series includes a broadcast storm protection
algorithm, which will automatically detect this condition, stopping the controller from
responding to the spurious traffic. If this algorithm is activated, the broadcast storm
diagnostic parameter will be set to ON (see "Network Sub List (nWrk)" on page 142).
18 HA032842ENG Issue 2
Page 19
Cybersecurity EPC3016, EPC3008, EPC3004
Communications watchdog
EPC3000-series controllers include a ‘comms watchdog’ feature. This can be
configured to raise an alert if any of the supported digital communications are not
received for a specified period of time. See the four watchdog
Main Sub-list" on page 107. These provide a way to configure appropriate action if
malicious action interrupts the controller’s digital communications.
parameters in "Loop -
Configuration backup and recovery
Using Eurotherm’s iTools software, you can ‘clone’ an EPC3000-series controller,
saving all its configuration and parameter settings to a file. This can then be copied
onto another controller, or used to restore the original controller’s settings—see
"Cloning" on page 213.
For cybersecurity reasons, passcode-restricted parameters are not saved in the
clone file when in operator mode (Level 1).
Clone files are digitally signed using an SHA-256 cryptographic algorithm, meaning
that if the file contents is tampered with, it will not load back into a controller.
Memory Integrity
FLASH Integrity
When an EPC3000-series controller powers up, it automatically performs an integrity
check on the entire contents of its internal flash memory. Additional periodic integrity
checks are also performed in 256 byte blocks during normal runtime. If any integrity
check detects a difference from what is expected, the controller will stop running and
display a
Non-volatile Data Integrity
When an EPC3000-series controller powers up, it automatically performs an integrity
check on the contents of its internal non-volatile memory devices. Additional periodic
integrity checks are performed during normal runtime and when non-volatile data is
being written. If any integrity check detects a difference from what is expected, the
controller enters Standby mode and displays a
appropriate (see "Notification Messages" on page 287 for more details).

Firmware
From time to time, to provide new functionality or address known issues, Eurotherm
may make new versions of the EPC3000-series firmware available.
This firmware may be downloaded from the Eurotherm website, and transferred to an
EPC3000 controller in the field, via a serial communications link, from a Windows PC
running a firmware upgrade utility.
CAUTION
NON SCHNEIDER ELECTRIC FIRMWARE
There is a potential risk that an attacker could upgrade an EPC3000 with
non-genuine firmware that contains malicious code. To mitigate this potential risk,
genuine EPC3000 firmware upgrade utility executables are always supplied
digitally signed with the publisher as Schneider Electric. Do not use a firmware
upgrade utility if it has not been signed by Schneider Electric.

Decommissioning
When an EPC3000-series controller is at the end of its life and being
decommissioned, Eurotherm advises reverting all parameters to their default settings
(see "Cold Start" on page 214 for instructions). This can help to protect against
subsequent data and intellectual property theft if the controller is then acquired by
another party.

Controller Concept
The EPC3000 is a range of programmable single loop process and temperature
controllers which are certified for cybersecurity communications robustness. A full
range of math, logic, totalizer and specialized functions is also available.
A simple "Quick Start" code is used to configure standard applications essential for
controlling specific processes. This enables fast commissioning "Out of the Box"
without the need for configuration software. Applications include (but are not limited
to) heat or heat/cool temperature control, carbon potential control, dew point control,
etc. These applications are pre-configured providing the user with a starting point for
customising to an individual process.
Eurotherm iTools is a software package which is designed for this purpose by

•
⁄4 DIN Model Number EPC3004
Universal input(s) accept various thermocouples, RTDs or process inputs.
Universal input/output (I/O) can be configured for control, alarm, re-transmission
outputs or contact inputs.
A changeover relay is available as standard in all controllers.
Controllers may be powered from either an ac line supply [100 - 230Vac +/-15%] or
low voltage [24Vac/dc (nominal) supply] depending on the order code.
EIA485 (RS485) digital communications is available in EPC3008 and EPC3004 as
standard and as an option in EPC3016.
Options available are:
1. A current transformer (CT) input plus a further contact input.
2. EtherNet communications protocol
3. EIA232/422 (RS232/422) digital communications using Modbus or EI-Bisynch
protocols is available in EPC3016 to provide compatibility with previous products.
The controller may be ordered against a hardware ordering code only ("Order Codes"
on page 25). In this case when it is new and first switched on 'out of the box' it will
start in a 'Quick Configuration' mode ("Start Up—New Unconfigured Controller" on
page 61). Alternatively, it may be ordered against both hardware and software codes,
in which case it will be supplied configured and will start up directly showing the
operator display ("Start Up - New Configured Controller" on page 65). Labels fitted to
the sleeve show the ordering code, serial number, date of manufacture, and terminal
connections for the hardware fitted.

This instrument is intended for permanent installation, for indoor use only, and
enclosed in an electrical panel.
Select a location which is subject to minimum vibrations the ambient operating
temperature is within 0 and 55
non condensing.
The instrument can be mounted on a panel up to 15mm thick.
To ensure effective panel sealing, mount on a non-textured surface.
Please read the safety information in "Safety and EMC" on page 11 before
proceeding. An EMC Booklet, part number HA025464, gives further installation
information and can be downloaded from www.eurotherm.co.uk.
o
C (32 - 131oF) and operating humidity of 0 to 90% RH
Panel Mounting the Controller
1. Prepare a cut-out in the mounting panel to the size shown. If a number of
controllers are to be mounted in the same panel observe the minimum spacing
shown, see "Recommended minimum spacing of controllers" on page 33.
2. Carefully remove the panel retaining clips from the sleeve.
3. To achieve effective panel sealing, make sure the gasket is not twisted and is
fitted behind the front bezel of the controller.
4. Insert the controller through the cut-out.
5. Spring the panel retaining clips back into place. Secure the controller in position
by holding it level and pushing both retaining clips forward.
6. Peel off the protective film from the display.
7. In the unlikely event that it should be necessary to remove the sleeve from the
panel, make sure that all power is turned off. Remove the controller from its
sleeve. Very carefully unhook the panel retaining clips from the side using a small
screwdriver.
The instrument includes polarizing features to help prevent the following:
a. The instrument being inserted upside down into sleeve.
b. Insertion of Low-Voltage PSU unit into High-Voltage PSU sleeve.
c. Insertion of other instruments that have a non-compatible terminal
assignment.

To Remove the Controller from its Sleeve
Ensure that the controller is powered down before attempting to remove it from its
sleeve. It can then be removed from its sleeve by easing the latching clips outwards
and pulling it forward out of the sleeve. When plugging it back into its sleeve, ensure
33 HA032842ENG Issue 2
that the latching clips click back into place to maintain the panel sealing.
If the Ethernet option is fitted, ensure that the Ethernet cable is removed from the rear
of the controller before removing it from its sleeve.

General Information About Relays and Inductive Loads
CAUTION
RELAYS/TRIACS AND INDUCTIVE LOADS
High voltage transients may occur when switching inductive loads such as some
contactors or solenoid valves. Through the internal contacts, these transients may
introduce disturbances which could affect the performance of the controller.
For these types of load it is recommended that a 'snubber' is connected across the
normally open contact of the relay switching the load. The snubber recommended
consists of a series connected resistor/capacitor (typically 15nF/100). A snubber
will also prolong the life of the relay contacts.
A snubber should also be connected across the output terminal of a triac output to
help prevent false triggering under line transient conditions.
When the relay contact is open or it is connected to a high impedance load, the
snubber passes a current (typically 0.6mA at 100Vac and 1.2mA at 230Vac).
You must ensure that this current will not hold on low power electrical loads. If the
load is of this type the snubber should not be connected.
Failure to follow these instructions can result in injury or equipment damage.

Current Transformer
The current transformer input is an option in EPC3016 controller. It is supplied as
standard in EPC3008 and EPC3004 controllers.
A further contact input (LA) shares a common terminal (C) with the CT providing up to
three (EPC3016) and five (EPC3008 and EPC3004) contact inputs altogether.
• C terminal is common to both the CT input and the contact input (LA). They are,
therefore, not isolated from each other, the sensor input or the logic outputs.
• CT input current: 0–50mA rms (sine wave, calibrated) 50/60Hz
• CT input resolution: 0.1A for scale up to 10A, 1A for scale 100A, 10A for scale up
to 1000A
• CT input accuracy: +1% of reading.
• A burden resistor, value 10, is fitted inside the controller.
RISK OF ELECTRIC SHOCK
It is recommended that the current transformer is fitted with a voltage limiting
device to help prevent high voltage transients if the controller is unplugged (for
example, two back-to-back zener diodes - the zener voltage should be between 3
and 10V, rated at 50mA).
Failure to follow these instructions will result in death or serious injury.
Contact Closure Input (LA)
This input is supplied with the current transformer, except on the Ethernet option in
EPC3016 where LA is available but the CT is not.
• Not isolated from the current transformer input, the sensor input or logic outputs
• Switching: 12Vdc at 40mA max
DANGER
• Contact open > 600. Contact closed < 300

EIA485 Wiring
EIA485 allows multi-slaves to be connected to the network. In practice a buffer is
necessary to convert EIA485 connections from the controller to the EIA232 port of
the PC. A suitable Communications Converter unit is recommended for this purpose.
The use of a EIA485 board built into the computer is not recommended since this
board may not be isolated and the RX terminals may not be biased correctly for this
application. This may cause electrical noise problems or damage to the computer.
Connections using a suitable converter are shown in the following diagram.
Note: The device physical interface can only support up to 31 devices for each
segment. More than 31 devices will require additional buffering. For more details see
the Communications Manual HA026230 which can be downloaded from
www.eurotherm.co.uk.

Start Up Modes
What’s in this Chapter
This chapter describes:
• What to expect when the controller is first switched on from new out of the box.
• A general description of the display and button functions.
• Power up after the instrument has been configured or commissioned.
Start up
Start Up (or Power Up) refers to the operation of the controller when Switched On.
EPC3000 range controllers are designed to be application based. Their start up
modes will, therefore, vary depending on the way in which the controller was ordered
and delivered. This chapter describes the different ways in which the controller can
be ordered and delivered and how this affects the operation at power up.
1. Controller new 'out of the box' supplied unconfigured. "Start Up—New
Unconfigured Controller" on page 61.
2. Controller new 'out of the box' supplied fully configured according to the order
code. "Start Up - New Configured Controller" on page 65.
3. Subsequent start ups - Controller previously configured. Go to section
"Subsequent Start-ups" on page 66.
Start up Diagnostic mode
In all cases the controller display will perform a diagnostic in which all bars of each
character and every beacon is illuminated. In a configured controller the diagnostic
display is followed by the firmware version number and the instrument type number,
then a short summary of the Quick Codes. (A new unconfigured controller shows the
Quick Codes only, see section "Start Up—New Unconfigured Controller" on page 61).
Essentially the start up diagnostics is the same for each model.
The opening display is then dependent upon its configuration status and is described
in subsequent sections.
The controller will read the idents of the hardware fitted. If a different hardware is
detected a message will be displayed and the instrument will go into standby mode.
To clear this message, either replace the module fitted with the expected module type
OR the expected module parameter value is to be changed to match the fitted
module parameter value.

Start Up—New Unconfigured Controller
If the controller is new and ordered and supplied unconfigured it will start up in 'Quick
Start Mode'. This is a built in tool which is provided to configure the product for the
most commonly used functions such as the application type, input type, range, and
digital input functions. The Quick Configuration code consists of two ‘SETS’ of five
characters each. The upper section of the display shows the set selected, the lower
section shows the five digits which make up the set. Each digit may result in multiple
parameter values being set. The opening set is SET1 as shown.
Initially all characters are shown as an
X. This is generally the default character for
‘not fitted/none’ or ‘use default’. The first character, initially flashing, selects the
Application Type as listed in the Quick Start Tables in the following sections. To select
the required application type press
or .
Note: Quick Code 1 will only be available if the correct hardware is fitted for the
application. For example, the VPU application must have IO1 and IO2 as relay, triac
or logic outputs.
Press
to select the second character. The second character selects the ‘Input 1
Type’ as listed in the Quick Start Tables in the following sections. If hardware or
features are not available then the character is skipped over when pressing scroll.
Continue to set up all 5 characters using the Quick Start Tables.
When the last character in SET1 has been entered the display will automatically go to
SET2.
Adjust these in the same way as SET1.
At any time to return to the start of SET1, press
WARNING
HAZARD OF INCORRECT CONFIGURATION.
Incorrect configuration can result in damage to the process and/or personal injury
and must be carried out by a competent person authorised to do so. It is the
responsibility of the person commissioning the controller to ensure the configuration
is correct.
Failure to follow these instructions can result in serious injury, or equipment
damage.
More detailed features available in the product may also be configured by entering a
Configuration Level. This is explained in "Configuration Level" on page 84, or by
using iTools as explained in "Configuration Using iTools" on page 181. iTools is a
configuration package available free of charge from Eurotherm by accessing
www.eurotherm.co.uk.

Quick Start Tables
The 1st digit in SET 1 will select an application which automatically configures
relevant function block parameters and creates wires between function blocks to
make a complete control strategy relevant to that application. Application ‘1’, Heat
only controller; application ‘2’ heat/cool controller; application ‘V’ VPU heat only
controller are generally covered by this manual. Other applications such as ‘C’ carbon potential and ‘D’ - dew point control are each provided as an addendum to the
User Manual and are available from www.eurotherm.co.uk.
The digits will present "X" when not fitted and the HMI will skip over that field.
Similarly, entering a value of "X" in a field will disable that feature, if appropriate.
Quick Code Set 1
Note: If no application is selected (1st character in SET 1 = X) the display will go
directly to the EXIT screen. If accepted the controller will take on a set of default
values. Any further configuration may be carried out by accessing the Configuration
Level ("Configuration Level" on page 84) or through iTools configuration software
("Configuration Using iTools" on page 181).
Note: For linear inputs the minimum/maximum input voltage/current will cause the
display to read range low/high respectively
Note: If the input 2 is not fitted Set 2 will be selected immediately after Input 1
Range has been set.
* Temperature, Carbon potential and dew point control are described as separate
supplements to this manual and are available from www.eurotherm.co.uk. Part

current; however, CT alarms will not be configured. This means that if CT alarms are
required they must be wired by the user. A typical example of wiring alarms is shown
in section "Example 1: To Wire an Alarm" on page 195.

To Save or Discard Quick Codes
When all characters have been entered the display will show:
If
No is selected (by pressing ) the display returns to SET1.
Press
or to select SAVE then either press to select or wait for 2
seconds to accept. This accepts the Quick Configuration Codes and the controller
enters Operator Level 1.
OR
Press
seconds to accept
or to select Disc then either press to select or wait for 2
. This discards the last entered codes and returns the controller to
its previous settings.
Selecting either SAVE or diSc will result in the instrument performing a restart.
To Re-Enter Quick Code mode
It is possible to re-enter Quick Start mode, by holding down the Page key during
power up.
It is then necessary to enter the configuration level passcode. See "To Select
Configuration Level" on page 87.
If the configuration of the instrument is subsequently modified by a change made via
Configuration Mode this will be shown by the quick code digits being separated by
the dp dot (indicating that the codes shown may not reflect the current configuration).
If the codes are then accepted the instrument is re-configured to satisfy the code
settings.
Note: If the config clip is connected the instrument may be powered from the USB
port of the PC. In this case it is necessary to disconnect the config clip to re-enter
Quick Start Mode. Alternatively, disconnect the power pins from the config clip. See
"Using the Configuration Clip" on page 182.
Note: If a Cold Start (See "Cold Start" on page 214) has been invoked the
instrument will always start in Quick Code Mode without the need to enter the
configuration passcode.

Start Up Modes EPC3016, EPC3008, EPC3004
Start Up - New Configured Controller
If a product has been ordered using the Order Code it will already be configured.
When new, ‘out of the box’, it will then power up in operating Level 1.
Also, if it has previously been configured, for example, using the Quick Codes then it
will start up in Operating mode.
The start up display is dependent upon the application or the way in which the
controller is configured, see ‘Start-up Modes’ in the following section.
Bar Graph
Setpoint
The view shown above is generally referred to as the ‘HOME’ Display.
In EPC3008 and EPC3004 the HOME display normally consists of three lines. The
upper line normally shows the Process Value "PV",
The centre line normally shows the Working Setpoint "WSP" if the controller is
working in its normal Auto mode or the Output demand if it is in Manual Mode.
The lower line shows a scrolling message providing a longer description of the
selected parameter. It may also display a further parameter value if this has been set
up in the instrument block, see "Display Functionality Sub-List (HmI)" on page 169.
In EPC3008 and EPC3004 a bargraph may also be configured using iTools. The
bargraph may be ‘soft’ wired to any convenient source such as PV input or output
demand, see "Example 4: To Configure a Bargraph" on page 196.
EPC3016 has two lines of display. The line below the top one alternates between a
mnemonic and the scrolling message. A bargraph is not available.
The Setpoint is defined as the value which the process is required to attain. The
value of the setpoint may be obtained from a number of sources, for example,
manually using the front panel keys, via the programmer function block, via an
external analogue source, via digital communications. The working setpoint is,
therefore, defined as the current setpoint derived from any of these sources.

Subsequent Start-ups
When the controller is no longer new and has been in normal use it will start up in
Level 1, even when it has been powered down in Operator level 2 or 3. If, however, it
was powered down when in Configuration level it will power up in ‘Standby’ and show
a message - ‘
re-enter configuration level (with password - see "To Select Configuration Level" on
page 87), then, either continue with changes to the configuration or accept existing
changes by exiting configuration level. The reason for this is that the controller may
have been part configured prior to shut down and either needs completion of the
configuration or confirmation that no further changes are required.
Start-up Modes
The controller may start in manual or in automatic mode depending on the setting of
the ‘Recovery Mode’ parameter, see section "Configuration Sub-List" on page 109.
If the Recovery Mode has been set to Manual (default) the controller will start in ‘Man’
mode. It will show the letter ‘

Start Up Modes EPC3016, EPC3008, EPC3004
Standby
Standby is the term given when the instrument strategy is not controlling due to the
following reasons:
• If the instrument is being configured i.e. in Quick Code Mode, Configuration
Mode or a clone file is being loaded.
• If the instrument has detected an unexpected condition (for example, was
powered down whilst in configuration mode, or fitted hardware does not match
expected hardware). See "Start up Diagnostic mode" on page 56 for more
information on unexpected conditions that will place the instrument into standby.
• If the instrument is forced into standby via the
Instrument.Diagnostics.ForceStandby parameter, see "Subsequent Start-ups" on
page 66.
When the instrument is in standby, the following occurs:
• All outputs are placed into their 'Off' state, unless being used as Valve Raise (Up)
/ Lower (Down) in which case the Standby Action is configurable (Rest, Up,
Down).
• The control loop will be placed into Hold.
• If an alarm has the Standby Inhibit parameter set to On, then the alarm is
inhibited (active alarms will be turned Off and new alarm conditions will not be
acted upon).
• If in standby due to the instrument being configured, a running program will reset.
WARNING
LOSS OF COMMUNICATIONS
If the output is not wired, but written to by communications, it will continue to be
controlled by the communications messages. In this case take care to allow for the
loss of communications.
Failure to follow these instructions can result in serious injury, or equipment
damage.

Operator Levels
What’s in this Chapter
This chapter describes the different operator levels:
• Operator Level 1
• Operator Level 2
• Introduction to Operator Level 3
• Return from a higher level to a lower level of operation
Overview
There are 5 levels of operation:-
1.
LEv1 - Level 1 has no passcode, the control is active and only the home list is
accessible.
2.
LEv2 - Level 2. The control is active and an extended home list is accessible.
3.
LEv3 - Level 3. The control is active and the complete operator parameter set is
shown and modifiable; the complete Configuration parameter set is shown, read
only; the user calibration (two point cal) facility is available.
4.
ConF - Configuration level is used to setup the whole controller; the
configuration parameters are accessible; the operator parameters are available,
without the need to switch to operator mode. The instrument calibration
parameters are also available in this mode. See "User Calibration" on page 278.
Levels 2, 3 and Configuration can be restricted by passcodes.
5. In addition the Quick Start Mode (See "Start Up—New Unconfigured Controller"
on page 61) is provided to configure the product in the minimum number of
operations. It is only available at power up after the instrument is cold started or
by holding the Page key during power up.

The display shown below is for a typical temperature controller.
Manual Mode
In general the current value of the process is shown in the upper display and, when in
‘Auto’ mode, the required value (Setpoint) is shown in the lower display. However,
this may depend, for example, upon the application or if the controller is in Manual
mode (see below).
Additional scrolling messages are shown, for example, when operator parameters
are selected (see section "Level 1 Operator Parameters" on page 72). These may be
standard descriptions of the parameter currently selected or they may be user
specific messages which have been set up using iTools. (See "Parameter Promotion"
on page 203).
In Operator Level 1 the controller may be placed into manual operation as follows:
• By default in EPC3008 and EPC3004 Auto/Manual may be selected by the user
by toggling the F1 button.
• By default in EPC3016 Auto/Manual may be selected by the user by pressing

System Messages
In addition to standard (or customised) scrolling messages, System Messages may
be shown at any time. A list of these is shown in "Notification Messages" on page 287
but a typical message may be ‘USING DEFAULT COMMS CONFIG PASSWORD’.
This is shown if the Comms Config Password has not been changed from its default
value. For example, it is possible to enter configuration mode via digital
communications which is restricted by a passcode. This passcode is only available
using iTools and should be changed from its default value to provide additional
security. When this has been done the message will not appear in the HMI in
operator level.
This particular message may also be disabled in Instrument Configuration mode, see
"Security Sub-List (SEC)" on page 171.
Bargraph
In EPC3008 and EPC3004 a bargraph may also be shown which displays the
configured value as a horizontal bar. This is set up in Configuration Level (See
"Display Functionality Sub-List (HmI)" on page 169).
Comms Configuration Active
The scrolling message ‘COMMS CONFIGURATION ACTIVE’ will be displayed if, for
example, iTools is connected to the controller and has been placed in configuration
mode by iTools.

timeout defaults to 60 seconds but can be adjusted between 0 and 60 seconds. A
setting of 0 means no timeout (see "Display Functionality Sub-List (HmI)" on
page 169), so that the HMI remains in the selected level.

Operator Levels EPC3016, EPC3008, EPC3004
Level 3 Operator Parameters
The Operator Level 3 lists are essentially the same as configuration level. These are
shown in the next chapter.
To Return to a Lower Level
From Level 3 you can select Level 1 or Level 2 as follows:
1. Press and hold until
2. Press
3. Press
or to select LEv1 (or LEv2)
to accept.
Goto is displayed
The display will briefly show PASS and will return to the selected level default display.
A security code is not required when going from a higher level to a lower level.
Note: if the controller had been switched off whilst operating in levels 2 or 3 it will
return to operator level 1 when switched on again. If it was switched off when in
configuration level it will start up with a message -
config mode

Navigation Diagram EPC3016, EPC3008, EPC3004
Navigation Diagram
The Navigation Diagram shows the series of operations of the front panel buttons
which are required to navigate to specific parameters.
For ease of access parameters are arranged in lists. Each list has a header and each
header is selected by repeated presses of the ’Page’ button
has a title, for example, the first header is the Analogue Input (AI LIST).
A list may have a number of instances. For example, if two Analogue Inputs are
supplied then the list is split into 1 INST and 2 INST selected using the ’Raise’ and
’Lower’ buttons /
Similarly a list may have a number of Sub-Lists. For example, the LOOP list. The
sub-lists are selected by entering the first sub-list, using the ’Scroll’ button , then
using the ’Raise’ or ’Lower’ buttons to select the following sub-lists.
When the appropriate list or sub-list has been selected use the ’Scroll’ button to scroll
through a list of parameters. Use the Page button to scroll back.
The Navigation Diagram which follows shows these button presses diagrammatically.
The Navigation Diagram generally includes all lists and all parameters available in
configuration level. Some parameters may not be shown in Level 3 and only those
lists and parameters which are required for a particular application are displayed on
the controller.

Configuration Level
Configuration of the instrument through the front panel is particularly useful where
relatively small changes are required on site, possibly during commissioning. For
larger or more detailed changes the use of Eurotherm iTools configuration package is
recommended and this is described in the next chapter.
What’s in this Chapter
• This chapter describes how to configure the controller through the HMI.
• Lists all parameters which are available in each function block
To Enter Configuration Level
The procedure is similar to that shown in "To Enter Level 3" on page 79.

Function Blocks
The controller is made up of a number of hardware and software function blocks.
Each block has inputs and outputs which are wired together in software (soft wired) to
match the application for which the controller is intended.
The following diagram shows an example of function blocks which make up a typical
controller.
The Temperature (or Process Value, PV) is measured by the sensor and compared
with a Setpoint (SP) set by the user.
The purpose of the control block is to reduce the difference between SP and PV to
zero by providing a compensating output to the plant via the output driver blocks.
The timer and alarms blocks may be made to operate on a number of parameters
within the controller, and digital communications provides an interface for data
collection, monitoring and remote control.
The way in which each block performs is defined by its internal parameters. Some of
85 HA032842ENG Issue 2
these parameters are available to the user so that they can be adjusted to suit the
characteristics of the process which is to be controlled.
These parameters are found in lists in Configuration Level.
The controller can also be configured using iTools as described in "Configuration
Using iTools" on page 181. iTools is proprietary software designed to configure
Eurotherm instruments and may be downloaded from www.eurotherm.co.uk.
Page 86
Configuration Level EPC3016, EPC3008, EPC3004
Configuration Level Parameters
In Configuration Level all parameters are organised in lists (in the same way as
Operator Level 3). Only parameters related to enabled functions are shown.
Each list may contain operator level and configuration parameters; the parameters
are only shown when the instrument is in the appropriate mode. If a list does not
contain at least one displayable parameter, it is not shown.
During navigation, the centre display (lower display in EPC3016) shows the
mnemonic code of the parameter or the List header. A scrolling string with either the
parameter or the List description is displayed in the lower section of the display.

To Select Configuration Level
WARNING
HAZARD OF INCORRECT CONFIGURATION
Incorrect configuration can result in damage to the process and/or personal injury
and must be carried out by a competent person authorised to do so. It is the
responsibility of the person commissioning the controller to ensure the configuration
is correct.
In configuration level the controller does not control the process or provide alarm
indication. Do not select configuration level during a live process.
Failure to follow these instructions can result in death, serious injury or
equipment damage.

Examples
Press
to scroll through each list header (the name of the function block) in turn
Pressing on one of these headers will do the following depending upon the
function block being accessed:
1. Display the first parameter (see Recipes).
2. Display the instance selection (see IO for named instances or Alarm for
numbered instances).
3. Display the subclass selection (see Loop).
When at 2 or 3 above, pressing up and down will cycle through the
instances/subclasses.
The following examples show how to navigate through different function blocks
Example 1: no additional instances and no sub-classes
The CT list is an example of a class which contains no additional instances and no
sub-classes. In other words it is a simple list of parameters under the heading CT
which set up the current transformer.
1. Press
until the list is displayed
2. Then press to scroll through the parameters.
3. To change the value of a selected read/write (R/W) parameter press
or .
Example 2: multiple instances and no sub-classes (named)
The io List is an example of a class which contains multiple instances and no
sub-classes. The instances are named instances, such as io.1, io.2, OP.3 etc (see
"I/O List (io)" on page 97). The list of parameters for each instance are not
necessarily the same.
The navigation diagram for this type of function block is shown below:
1. Press
2. Press to select the first instance of the
to scroll to the io List
io parameters. This is displayed as
io.1 and INST and denotes that this is the first instance of parameters in that
category
3. Press again to scroll through parameters for
io.1 or, to select the next
and subsequent instances press

Example 3: multiple instances and no sub-classes (numbered)
The Alarm List is also an example of a class which contains multiple instances and
no sub-classes. The instances in this case are numbered instances, such as 1 to 6
"Alarms List (ALm)" on page 131. The list of parameters for each instance are not
necessarily the same.
Example 4: single instance and multiple sub-classes
The Loop List is an example of a class that has a single instance and multiple
sub-classes. A sub-class (or List) groups parameters under meaningful
sub-headings. For example, all parameters associated with the setpoint are grouped
together in the SP List (displayed as
S.LIST). Each subclass will be different.
The navigation diagram for this type of function block is shown below:
Example 5: multiple instances and multiple sub-classes
The communications list is an example of a class which has multiple instances and
multiple sub-classes. The instances are Fixed and Option and the Sub Lists are
Main, Network, Broadcast.

0 to 60 Some industrial installations can cause electrical noise to be
introduced into the process measurement. This could be due, for
example, to EMC or mechanical linkages. A filter is provided to
reduce the frequency of electrical noise seen by the instrument.
The effect of electrical noise can be reduced by increasing the
filter time constant, but a compromise must be achieved as it
could affect the closed loop response of the system.
The larger the number, the slower the measured temperature will
be to respond to fluctuations.

AutO 0 A thermocouple measures the temperature difference between
the measuring junction (hot junction) and the reference junction
(cold junction). Auto uses the measurement of the temperature
made by the instrument where the thermocouple is connected to
its rear terminals.
Default: Auto

thermocouple measurement is made by an external transmitter
which does not linearise the thermocouple curve.
Off 0 The controller continuously monitors the impedance of a
transducer or sensor connected to the input. Off means sensor
break is not detected.
LO 1 Sensor break is detected if impedance at the terminals is above a
low threshold (typically between 3 to 5KOhms)
Default: Low

The CJC temperature is a measure of the temperature at the
instrument terminals. It is relevant only for thermocouple inputs
and is provided as a diagnostic aid.
Process value is the displayed value on the instrument, usually
the measured temperature when the instrument is controlling a
temperature loop.
The state of the PV is continuously monitored.

INV 1 Output inverted
0 Minimum pulse time in seconds. This value sets the minimum
duration between any two switching events. Although it is named
'MinOnTime', it applies to both on and off pulses equally.
A contactor datasheet will often specify the minimum pulse time that
will help to ensure correct energizing and de-energizing of the
contactor. This may be the lowest value you should consider using as
a MinOnTime.
Auto(0) - Automatically sets the minimum on time for the output
hardware as follows:
Relay = 1s (time proportioning) or 0.1s (VP raise/lower),
Logic = 0.05s (time proportioning), 0.1s (VP raise/lower)
Alternatively, a value may be set manually but it should be noted that
this value will be clipped if it is below the minimum permissible value
for the hardware that is fitted (relay or logic - see settings above).
For VP raise/lower outputs, smaller values of MinOnTime may
actually produce less actuator activity. This is because the larger the
MinOnTime, the larger the valve movement, and thus the lower the
output resolution. This may lead to increased hunting. Generally
values less than 0.5s should be used.
Default: Auto
0 This value sets the time proportioning output (TPO) and cycle time in
seconds. It is defined as the period of time between output
repetitions.
When this parameter is Auto (0), which is the default setting, the TPO
algorithm will run in a so-called Constant Ripple Mode. Under this
regime, the cycle time will be automatically and continuously
adjusted depending on the output demand. This is to maintain the
amount of ripple in the process at an approximately constant
amplitude. The benefit of this is that actuations are reduced on
average, which can increase the lifetime of contactors and relays. As
suggested, a demand of 50% will produce the shortest cycle time of
4*MinOnTime, and the cycle time is extended the further the demand
moves away from 50%. You should therefore choose a MinOnTime
that gives an appropriate minimum cycle time.
Alternatively, you can set a value of cycle time directly. When a value
is set, the algorithm will run in a so-called Constant Cycle Time
Mode. Under this regime, the algorithm will try to keep the cycle time
constant, assuming constant demand. Note that the cycle time will be
extended if the demand is such that the cycle time cannot be
achieved without violating the MinOnTime. In this case, the effective
cycle time will be extended just enough to help ensure the
MinOnTime and the demand are both achieved.
There are a number of factors that may influence the setting of an
appropriate CycleTime and it is often a trade off. For example, a
longer cycle time may extend the lifetime of contactors but reduce the
lifetime of heating elements. A longer cycle time will also increase the
amount of ripple in the process variable.
Default: Auto
This is the normal setting for control.
Output off when the PID demand is off. For control this is when
PV>SP.
For a Digital Input the input is active when the input is = 1
Default: Normal
This is the normal setting for alarms.
Output off is when the alarm is active.
Output on is when the alarm is in-active.
For a Digital Input the input is active when the input is = 0
