ProVU4 Controller, Profiler & Recorder/Controller - Product Manual
1 Introduction
This product is a 1/4 DIN size (96 x 96mm front) microprocessor based graphical process
controller, featuring a 160 x 80 pixel, monochrome LCD with a dual colour (red/green)
backlight. It can control process variables from a variety of sources such as temperature,
pressure, flow and level.
The operating voltage is either 100-240V at 50/60 Hz or 24V-48V AC/DC depending on the
model purchased. Optional features include a USB interface, RS485 or Ethernet
communications, profile controlling and data recording. Non-volatile memory protects against
data or configuration loss during power outages. If the unit is left un-powered, a lithium
battery powers the data recorder’s real-time clock for a minimum of one year.
The USB Interface option allows uploading or downloading instrument configuration settings
to/from a USB memory stick, for easy configuration of multiple instruments or transfer to/from
the PC configuration software. If the Data Recorder of Profiler options are fitted, recordings
and profile information can also be transferred via the memory stick.
The Data Recorder option allows the user to make recordings over time. Recordings can be
transferred to a memory stick using the USB Port or downloaded using one of the
communications options.
The Profiler option allows the user to predefine up 255 segments, shared amongst up to 64
Setpoint Profiles. These control the setpoint level over time, increasing, decreasing or
holding its value as required. When combined with the real-time clock of the Data Recorder
option, the profiling capabilities are expanded to allow automatic program start at a defined
time and day.
Inputs are user configurable for thermocouple and RTD probes, as well as linear process
signal types such as mVDC, VDC or mADC. Multipoint scaling can compensate for nonlinear signals. Output options include relays, SSR drivers, triacs or linear mV/voltage
modules. These can be used for process control, alarms or retransmission of the process
variable or setpoint to external devices. A Transmitter Power Supply option module can
provide an unregulated 24V DC (22mA) auxiliary output voltage for external signal
transmitters.
Alarm indication is standard on all instruments; up to five alarms can be defined. Alarms may
be set as process high or low, deviation (active above or below controller setpoint), band
(active both above and below setpoint), rate of input change, control loop or signal break
types. Alarm status can be indicated by lighting an LED’s, changing the display backlight
colour or viewing the alarm status screen. These alarms can be linked to any suitable output.
The controller can be programmed for on-off, time proportioning, or current proportioning
control implementations, depending on the output modules fitted, and feature manual or
automatic tuning of the PID parameters. A secondary control output is available when
additional output modules are fitted. Optional analogue Remote Setpoint inputs can be
included. Configuration of the major settings is made easy by a Setup Wizard that runs
automatically at first ever power-up or whenever option modules have been changed. Access
to the full range of parameters is via a simple menu driven front panel interface, or the PC
based configuration software.

2 Installation
Unpacking
1. Remove the product from its packing. Retain the packing for future use, in case it is
necessary to transport the instrument to a different site or to return it to the supplier for
repair/testing.
2. The instrument is supplied with a panel gasket and push fit fixing strap. A single sheet
concise manual is also supplied in one or more languages. Examine the delivered items
for damage or defects. If any are found, contact your supplier immediately.
Installation
CAUTION:
Installation should be only performed by technically competent personnel. It is the
responsibility of the installing engineer to ensure that the configuration is safe.
Local Regulations regarding electrical installation & safety must be observed (e.g.
US National Electrical Code (NEC) or Canadian Electrical Code).
Figure 1. Main dimensions
Panel-Mounting
The mounting panel must be rigid and may be up to 6.0mm (0.25 inches) thick. The cut-out
size is:
92mm x 92mm (+0.5mm / -0.0mm).

Instrument
and instrument is clamped in
Instruments may be mounted side-by-side in a multiple installation, but instrument to panel
moisture and dust sealing will be compromised. Allow a 20mm gap above, below and behind
the instrument for ventilation. The cut-out width (for n instruments) is:
(96n - 4) mm or (3.78n - 0.16) inches
If panel sealing must be maintained, mount each instrument into an individual cut-out with
6mm or more clearance between the edges of the holes.
Note:
The mounting clamp tongues may engage the ratchets either on the sides or the
top/bottom faces of the Instrument housing. When installing several Instruments side-byside in one cut-out, use the ratchets on the top/bottom faces.
CAUTION:
Ensure the inside of the panel remains within the instrument operating temperature
and that there is adequate airflow to prevent overheating.

4 Electrical Installation
CAUTION:
Installation should be only performed by technically competent personnel. It is the
responsibility of the installing engineer to ensure that the configuration is safe.
Local Regulations regarding electrical installation & safety must be observed (e.g.
US National Electrical Code (NEC) or Canadian Electrical Code).
Installation Considerations
Ignition transformers, arc welders, motor drives, mechanical contact relays and solenoids are
examples of devices that generate electrical noise in typical industrial environments. The
following guidelines MUST be followed to minimise their effects.
1. If the instrument is being installed in existing equipment, the wiring in the area should be
checked to ensure that good wiring practices have been followed.
2. Noise-generating devices such as those listed should be mounted in a separate
enclosure. If this is not possible, separate them from the instrument, by the largest
distance possible.
3. If possible, eliminate mechanical contact relays and replace with solid-state relays. If a
mechanical relay being powered by an output of this instrument cannot be replaced, a
solid-state relay can be used to isolate the instrument.
4. A separate isolation transformer to feed only the instrumentation should be considered.
The transformer can isolate the instrument from noise found on the AC power input.
AC Power Wiring - Neutral (for 100 to 240V AC versions)
It is good practice to ensure that the AC neutral is at or near ground (earth) potential. A
proper neutral will help ensure maximum performance from the instrument.
Wire Isolation
Four voltage levels of input and output wiring may be used with the unit:
1. Analogue input or output (for example thermocouple, RTD, VDC, mVDC or mADC)
2. Relays & Triac outputs
3. SSR Driver outputs
4. AC power
CAUTION:
The only wires that should run together are those of the same category.
If any wires need to run parallel with any other lines, maintain a minimum space of 150mm
between them.
If wires MUST cross each other, ensure they do so at 90 degrees to minimise interference.
Page 22 Wiring Instructions 59407, Issue 1 – March 2008
Page 24
ProVU4 Controller, Profiler & Recorder/Controller - Product Manual
Use of Shielded Cable
All analogue signals must use shielded cable. This will help eliminate electrical noise
induction on the wires. Connection lead length must be kept as short as possible keeping the
wires protected by the shielding. The shield should be grounded at one end only. The
preferred grounding location is at the sensor, transmitter or transducer.
Noise Suppression at Source
Usually when good wiring practices are followed, no further noise protection is necessary.
Sometimes in severe electrical environments, the amount of noise is so great that it has to be
suppressed at source. Many manufacturers of relays, contactors etc supply 'surge
suppressors' which mount on the noise source. For those devices that do not have surge
suppressors supplied, Resistance-Capacitance (RC) networks and/or Metal Oxide Varistors
(MOV) may be added.
Inductive coils:- MOVs are recommended for transient suppression in inductive coils,
connected in parallel and as close as possible to the coil. Additional protection may be
provided by adding an RC network across the MOV.
Figure 5. Transient suppression with inductive coils
Contacts:- Arcing may occur across contacts when they open and close. This results in
electrical noise as well as damage to the contacts. Connecting a properly sized RC network
can eliminate this arc.
For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor
(1000 volts) is recommended. For circuits from 3 to 5 amps, connect two of these in parallel.
Figure 6. Contact noise suppression
59407, Issue 1 – March 2008 Wiring Instructions Page 23
Page 25
ProVU4 Controller, Profiler & Recorder/Controller - Product Manual
Sensor Placement (Thermocouple or RTD)
If the temperature probe is to be subjected to corrosive or abrasive conditions, it must be
protected by an appropriate thermowell. The probe must be positioned to reflect true process
temperature:
1. In a liquid media - the most agitated area
2. In air - the best circulated area
CAUTION:
The placement of probes into pipe work some distance from the heating vessel
leads to transport delay, which results in poor control.
For a two wire RTD a wire link should be used in place of the third wire. Two wire RTDs must
only be used with lead lengths less than 3 metres. Use of three wire RTDs is strongly
recommended.
Thermocouple Wire Identification Chart
The different thermocouple types are identified by their wires colour, and where possible, the
outer insulation as well. There are several standards in use throughout the world.
The table below shows the wire and sheath colours used for most
common thermocouple types. The format used in this table is:

carefully the supply voltage and connections before applying power.
Powering Up Procedure
At power up, a self-test procedure is automatically started, during which a splash screen is
displayed and the LED indicators are lit. At the first power up from new, or if the option
modules are changed, the Setup Wizard will run, indicating configuration is required (refer to
the Setup Wizard section of this manual). At all other times, the instrument returns to
Operation Mode once the self-test procedure is complete.
Front Panel Overview
The illustration below shows the instrument front panel. The USB socket to the right of the
keypad is fitted to USB and Data Recorder versions only.
Clean the front panel by washing with warm soapy water and dry immediately If the USB
option is fitted, close the USB port cover before cleaning.

8 The USB Interface
The features covered in this section of the manual are available on models fitted with the
optional USB Interface and the Data Recorder version, which includes the USB Interface.
Using the USB Port
The USB Interface option allows the user to upload or download instrument settings to or
from a USB memory stick. This allows easy configuration of multiple instruments or the
transfer to or from the PC configuration software. If the Data Recorder or Profiler options are
fitted, recordings and profile information can also be transferred via USB memory stick. Refer
to the USB Menu section for more details.
USB Memory Stick Folders & Files
When a USB stick is inserted, the instrument looks for, and if necessary creates the DEVICE,
CONFIG, PROFILE and RECORDER folders. Files must be located in these folders in order
to be used. When preparing to upload files from your PC, ensure that you save them to the
correct folder on the memory stick.
DEVICE – This folder must be located in the
Root of the USB memory stick
CONFIG – Configuration files (*.bct)
PROFILE – Profile program files (*.pfl)
RECORDER – Recorder log folders/files The
user is asked for a new recorder sub-folder
name before transferring recorder data to USB.
The log files (*.csv) are placed in this folder.
CAUTION:
If the file or folder named already exists, data will be overwritten
The first recorder log file written is named 000001-1.csv and placed in the new Recorder
sub-folder. Stopping/starting a recording does not create a new file, but each time the
parameters being recorded are changed a new file is created (e.g. 000002-1.csv then
000003-1.csv etc). If any of these files would exceed 65500 data lines, a new file is created
with the last digit incremented by 1 (e.g. 000001-2.csv then 000001-3.csv).
Note:
To speed up the disk operation, keep the number of files stored in these folders to a
minimum.
CAUTION:
Do not remove the memory stick from the USB port whilst a data transfer operation
is in progress. Data loss or corruption may result.

9 The Data Recorder Option
The features covered in this section are available on models fitted with the Data Recorder
option. This option includes a USB Interface (refer to section 8) and a battery backed-up
Real Time Clock (RTC).
Introduction
The Data Recorder option allows the user to make a record their process over time.
Recordings can be transferred to a memory stick using the USB Port or downloaded using
one of the serial communications options?????.
Recordings are stored in Comma Separated format (.csv), suitable for use with
spreadsheets, or for import in to other software. See the USB Memory Stick Folders & Files
details (in section 8) for file information.
A Recorder option is added to the Configuration Menu and recorder control can be optionally
added to the Main Menu or Operation Mode. The RTC also expands the profiling capabilities
(refer to section 10) and allows a “calibration due” reminder to be shown at a date specified
by the user.
Changes To Operation Mode
The Data Recorder adds the option for a Calibration Reminder and a % memory use bar
graph to the Operation Mode screen sequence.
Calibration Reminder
A "calibration due reminder" can be shown if the date is equal to or after the Calibration
Reminder Date. The reminder screen persists until the key is pressed. If due, the reminder
is shown at Power-up, and repeated every 24hrs until the reminder date is changed.
The Calibration Reminder enable/disable and Reminder Date parameters are set in the Input
Configuration Menu.
Memory Use Bar Graph
The bar graph shown in the main Operation Mode screen has the option to show memory
used in place of the standard PID power or control deviation options. This graph shows the
0-100% memory used. The Bar Graph Format is defined in the Display Configuration Menu.

10 The Profiler Option
The features covered in this section are only available on models fitted with the Profiler
(Setpoint Programmer) option. If the instrument also has the Data Recorder option fitted, it’s
Real Time Clock is used to expand the profiling capabilities by adding Day & Time profile
start options, releasing of hold segments at a specific time of day and changing the power fail
recovery option based on the length of time the power has been off for. These features are
explained below and in the Profiler Setup and Profile Control menus (refer to section 7)
Introduction
The Profiler option allows the user to store up to 255 profile segments, shared between a
maximum of 64 Profiles. Each profile controls the value of the setpoint over time; increasing,
decreasing or holding its value as required. If fitted, Profiler options are added to the Main
Menu as well as the Operation Mode.
Profiler Enabling
Controllers supplied without the Profiler option installed can be upgraded in the field by
purchasing a licence code number from your supplier. Refer to the Field Upgrade information
(Section 3) for more details.
Profile Components
The General Profile Configuration settings decide how profiles can be Run, Held or Aborted.
These settings apply to all profiles. Each profile has it’s own header information plus 1 or
more segments.
Profile Header & Segment Information
The profile header contains information about how the profile starts and stops, the power
loss recovery action and if it should repeat.
Note:
Profile Header information is stored to memory as the Segment creation sequence begins.
No profile is created if you exit before this point.
Segments can be ramps, dwells, steps or special segments such as holds, ends or joins.
Note: Segment information is stored as each segment is created, but the profile remains
invalid until an end or join segment is defined.

Target Setpoint
Profile Starting & Standard Segments
The example below shows two profiles containing examples of the standard segment types
required to make simple profiles or profile sequences. A Start Trigger is the instruction to
begin the selected profile. Depending on the Run/Hold Signal parameter setting in the Profile
Setup Menu, this can be from a Key-press given in the appropriate screen, a digital input
signal or via a serial communications command.
Following a Start Trigger, profiles can start immediately, after a delay, or from the Timer
(Timer start available on Recorder version only).
CAUTION:
A timer start time should not clash with other profiles. A profile will not start if
another is running, including delays caused by Manual or Auto-Hold.

Ramps, Dwells and Step Segments have an end of segment Target Setpoint. If the 1
st
segment is a Ramp- Time, the slope needed to reach the target will be changed by the
Starting Setpoint value. For a Ramp-Rate segment, the time will change instead. A Dwell
(sometimes called a soak) holds the last segment’s value for the specified Dwell Time. Step
segments jump straight to the new target setpoint value.
If the last segment is a Join, the join target profile will start. Note: The profile sequence will
abort if the join target has been deleted. An End segment ends the profile sequence.

Example:
Loops Segments
A Loop Segment goes back to a specified segment. This action is repeated for the required
number of times (1 to 9999) before the profile continues onwards. More than one Loop
Segment can be used in a profile, but they must not cross.

A Hold during a segment maintains the current setpoint value. Once the hold is stopped the
Ramp or Dwell continues. Depending on the configuration, a hold can be the started &
stopped by via a key-press, breaking the signal to a Run/Hold digital input, a serial comms
command or by the Auto-Hold feature (see below).
Note:
A running profile will also hold while Manual Control is selected.
A Hold Segment is a pre-planned hold, programmed into the profile. It maintains the value of
the previous segment. The profile does not continue until a Continue Trigger occurs. This
can be via a key-press, a digital input signal or after waiting for a time of day (available on
Recorder version only).

The Auto-Hold Feature
Each profile segment has individual Auto-Hold settings. If utilised, these ensure that the
profile and the actual process remain synchronised. If the process does not closely match
the required setpoint by remaining within the Hold Band, the profile can be held until it
returns within bounds.
The user can choose to hold the profile if the process beyond the Hold Band Above The
Setpoint only, Below The Setpoint only or to Band (either side of the setpoint). When AutoHold is active, the profile status is shown as “Held”.

Power/Signal Lost Recovery Actions
If there is a power cut while a profile is running, the instrument will use the defined Profile
Recovery Method once the power has been restored.
If there is a break in the input while a program is running, the unit will go to the Pre-Set
Power Value during the break condition. Once the condition has ended it carries out the
same recovery action as specified for power failure.
Note:
Recorder versions always use option E (Continue profile from the point it had reached
when the power failed) if the Power Off Time is less than the Profile Recovery Time
setting. If the power is off for more than this time, the defined Profile Recovery Method is
used.

11 Manually Tuning Controllers
Single Control Tuning (PID with Primary Output only)
This technique balances the need to reach setpoint quickly, with the wish to limit setpoint
overshoot at start-up or during process changes. It determines values for the Primary
Proportional Band and the Integral and Derivative time constants that allow the PID control
algorithm to give acceptable results in most applications that use a single control device.
CAUTION:
This technique is suitable only for processes that are not harmed by large
fluctuations in the process variable.
1. Check that the Setpoint Upper Limit and Setpoint Lower Limit are set to safe levels for
your process. Adjust if required.
2. Set the Setpoint to the normal operating value for the process (or to a lower value if
overshoots beyond this value might cause damage).
3. Select On-Off control (i.e. set the Primary Proportional Band to zero).
4. Switch on the process. The process variable will oscillate about the setpoint. Record the
Peak-to-Peak variation (P) of the first cycle (i.e. the difference between the highest value
of the first overshoot and the lowest value of the first undershoot), and the time period of
the oscillation (T) in minutes. See the example diagram below - Manually Tuning PID.
5. Calculate the PID control parameters using the formula below. P.Pb is the Primary
Proportional Band, Int.T is the Integral Time Constant, and Der.T is the Derivative Time
Constant. The Input Span is the difference between Scale Range Lower Limit and Scale
Range Upper Limit:
P.Pb
= x 100

Dual Control Tuning (PID with Primary and Secondary Outputs)
This tuning technique balances the need to reach setpoint quickly, with the wish to limit
setpoint overshoot at start-up and during process changes. It determines values for the
Primary Proportional Band, Secondary Proportional Band, Integral and Derivative time
constants that allow the PID control algorithm to give acceptable results in most applications
that use dual control (e.g. Heat & Cool).
CAUTION:
This technique is suitable only for processes that are not harmed by large
fluctuations in the process variable.
1. Tune the controller using only the Primary Control output as described in the Single
Control Tuning section above.
2. Set the Secondary Proportional Band to the same value as the Primary Proportional Band
and monitor the operation of the controller in dual control mode. If there is a tendency to
oscillate as the control passes into the Secondary Proportional Band, increase its value. If
the process appears to be over-damped (slow to respond) in the region of the Secondary
Proportional Band, decrease its value.
3. When the PID tuning values have been determined, if there is a disturbance to the
process variable as control passes from one proportional band to the other, set the
Overlap/Deadband parameter to a positive value to introduce some overlap. Adjust this
value by trial and error until satisfactory results are obtained.
PI Tuning (Valve, Damper& Speed Controller)
This tuning technique is used when controlling a damper, a modulating valve or motor speed
controller. It determines values for the Primary Proportional Band, and Integral Time
Constant. The Derivative Time Constant is normally set to OFF. This type of control (known
as PI Control) minimises valve/motor wear whilst giving optimal process control.
CAUTION:
This technique is suitable only for processes that are not harmed by large
fluctuations in the process variable.
1. Set the setpoint to the normal operating process value (or to a lower value if overshoot
beyond this value is likely to cause damage).
2. Set controller to On/Off Control mode (i.e. set Primary Proportional Band to the minimum
value).
3. Set the Integral Time Constant to OFF.
4. Set the Derivative Time Constant to OFF.

Fine Tuning.
A separate cycle time adjustment parameter is provided for the Primary and Secondary
control when using time proportioning control outputs.
Note:
Adjusting the cycle time affects the controllers operation; a shorter cycle time gives control
that is more accurate, but mechanical components such as relays have a reduced life
span.
1. Increase the width of the proportional band if the process overshoots or oscillates
excessively.
2. Decrease the width of the proportional band if the process responds slowly or fails to
reach setpoint.
3. Increase the automatic reset until the process becomes unstable, then decrease until
stability has been restored.
Note:
Allow enough time for the controller and process to adjust.
4. Initially add rate at a value between 1/4th and 1/10th of the automatic reset value.
5. Decrease Rate if the process overshoots/undershoots or oscillates excessively.
Note:
When controlling a modulating valve, it is recommended that Derivative is set to OFF to
avoid excessive valve activity. Derivative can cause process instability in these processes.
6. After making all other adjustments, if an offset exists between the setpoint and the process
variable use the Bias (manual reset) to eliminate the error:
Below setpoint - use a larger value
Above setpoint - use a smaller value.

12 Serial Communications
Supported Protocols
Communication with a Modbus RTU or Modbus TCP master device is possible if the
appropriate communications module is fitted into Option Slot A. An RS485 Module is
required for Modbus RTU. An Ethernet Module is required for Modbus TCP.
The instrument can also act as Setpoint Master over RS485 in multi-zone applications. In this
mode the unit continuously sends it’s setpoint value using Modbus broadcast messages.
For a complete description of the Modbus protocol refer to the description provided at
http://www.modicon.com/ or http://www.modbus.org/
All models also have a configuration socket for use with the PC configuration software. An
RS232 to TTL lead (available from your supplier) is required in order to use this socket.
A front mounted USB port is available on some models; this can also be used to configure
the instrument or to transfer recorder or profile files via a USB memory stick.
RS485 Configuration
The RS485 address, bit rate and character format are configured via the front panel from the
Comms Configuration menu or by using the PC Configurator software.
Physical layer configuration settings possible are:
Data rate: 4800, 9600, 19200, 38400, 57600 or 115200 bps
Parity: None (default), Even, Odd
Character format: Always 8 bits per character.
Device Address: See below.
RS485 Device Addressing
The instrument must be assigned a unique device address in the range 1 to 255. This
address is used to recognise Modbus Queries intended for this instrument. With the
exception of broadcast messages, the instrument does not respond to Modbus Queries that
do not match the address that has been assigned to it.
The instrument will accept broadcast messages (global queries) using device address 0 no
matter what device address is assigned. No responses are returned for globally addressed
Queries.
Ethernet Configuration
For Modbus TCP communications (Modbus over Ethernet), the IP address can either be
assigned by a Dynamic Host Configuration Protocol (DHCP), BootP or AutoIP server on the
network, or manually assigned using the IP address allocation software tool.
Refer to the PC Software section of this manual for more information setting IP addresses.
The supported data rates 10/100BASE-T (10 or 100 Mbps) are automatically detected.

MODBUS
SLAVE
QUERY
RESPONSE
Link Layer
A Query (or command) is transmitted from the Modbus Master to the Modbus Slave. The
slave instrument assembles the reply to the master. All of the instruments covered by this
manual are slave devices, and cannot act as a Modbus Master.
MASTER
INSTRUMENT
Figure 48. Modbus Link Layer
A message for either a QUERY or RESPONSE is made up of an inter-message gap followed
by a sequence of data characters. The inter-message gap is at least 3.5 data character times
- the transmitter must not start transmission until 3 character times have elapsed since
reception of the last character in a message, and must release the transmission line within 3
character times of the last character in a message.
Note:
Three character times is approximately 0.25ms at 115200 bps, 0.51ms at 57600 bps,
0.75ms at 38400 bps, 1.5ms at 19200 bps, 3ms at 9600 bps and 6ms at 4800bps.
Data is encoded for each character as binary data, transmitted LSB first.
For a QUERY the address field contains the address of the slave destination. The slave
address is given together with the Function and Data fields by the Application layer. The
CRC is generated from the given address, function and data characters.
For a RESPONSE the address field contains the address of the responding slave. The
Function and Data fields are generated by the slave application. The CRC is generated from
the address, function and data characters.
The standard MODBUS RTU CRC-16 calculation employing the polynomial 216+215+22+1 is
used.

13 Modbus Parameters
The Modbus parameter addresses are detailed in the tables below.
The Access column indicates if a parameter is read only (RO) or if it can also be written to
(R/W). Communications writes will not implemented if the Writing Via Serial Comms
parameter in the Comunications Configuration menu is set to Disabled.
Note:
Some of the parameters that do not apply for a particular configuration will accept reads
and writes (e.g. attempting to scale a Linear output which has not been fitted). Read only
parameters will return an exception if an attempt is made to write values to them.
Data Formats
Data can be read or written in three formats: Integer Only, Integer with 1 Decimal Place and
Floating Point Number.
The Modbus Address column shows the register address for each parameter in integer
format. Other formats can be calculated from the Integer Only address.
When working in Hexadecimal, the format calculations are:
Address for Integer with 1 Decimal Place = Integer address plus 0x4000
Address for Floating Point = Integer address multiplied by 2, plus 0x8000
When working in Decimal, the format calculations are:
Address for Integer with 1 Decimal Place = Integer address plus 16384
Address for Floating Point = Integer address multiplied by 2, plus 32768
