Re-fitting the Main Boards

This product is designed to allow the user to reconfigure some hardware options in
the field by changing the modules fitted in slots 1, 2, 3, & A. The main boards
(display/CPU, power supply, inputs 1 & 2 and digital input/USB) are factory fitted, but
may be removed while reconfiguring the plug-in modules. Take care when re-fitting
these boards. Observe the power supply board transformer colour, and case labelling
to check the supply voltage, otherwise irreparable damage may occur.

CAUTION: In the event of a fault, replacement of defective main boards

should only be carried out by trained personnel.

NOTE: For an effective IP66 seal against dust and moisture, ensure

gasket is well compressed against the panel, with the 4 tongues
located in the same ratchet slot.

Rear Terminal Wiring

CAUTION: The instrument is double insulated. All external circuits

connected must provide double insulation.
Failure to comply with the installation instructions may impact the
protection provided by the unit.

CAUTION: Check correct operating voltage on the side label before

connecting power. A UL listed anti-surge fuse should be fitted to the
power input. An IEC60947-1 & IEC60947-3 compliant isolation switch
should be fitted close to the unit, in easy reach of the operator, and
appropriately marked.

NOTE: The wiring diagrams show all possible option combinations. The

connections required depend on the options & modules fitted.
Use single strand (1.2mm / AWG18 max size) copper wire, except for
thermocouple inputs, where the correct thermocouple or compensating
cable and connectors should be used.

Central Terminals 1 to 24

CAUTION: External computing devices connected to the

communications port must comply with the standard, UL 60950.

Outer Terminals 25 to 42

2. POWER UP SEQUENCE

Following the power-up self-test and logo screen, the instrument normally enters
Operation Mode, from which the user can select the instrument’s Main Menu (refer to
the Screen Sequences on page 5). The exceptions to this are the first power-up after
purchase where the Setup Wizard is shown, or if a plug-in module error is detected.

Plug-in Module Errors

If an invalid or unknown module is detected in one of the plug-in module slots the
message “Fault Found, Press R, for details” followed by “Replace faulty module in
Module Slot n, Press R,” (where n identifies the problem slot). The Service Contact

information is displayed next showing details of who to contact if a fault persists

CAUTION: Do not continue using the product until the issue causing

the error is resolved.

3. OPERATION MODE

This mode is entered at power on, or can be accessed from the Main Menu.
The initial screens shown in operation mode vary depending on the options fitted and
the configuration. Subsequent screens display and may allow the selection or
adjustment* of Setpoints, setpoint ramps, enable/disable control, auto/manual
operation, alarm status, profiler & recorder status and graphical trend views.
Some screens will persist until the user navigates away, others will ‘time-out’ back to
the main screen (refer to Operation Mode: in Screen Sequences).

Press R or L briefly to move forward/back through parameters. Where adjustment is
possible*, press D or U to alter the values. The next/previous screen follows the last
parameter - or hold down R or L >1sec to skip straight to next/previous screen

accepting ALL values shown.

* If required, all Operation Mode parameters can be made read only (see Display
Configuration on page 6) and others may be removed from this mode altogether.

NOTE: Configuration must be completed before starting normal

operations.

back through the last 240 data points.

NOTE: Data is not retained at power down or if the sample interval is

changed.

Manual Control

Depending on the Control Configuration settings, automatic or manual control can be
selected from the Auto/Manual selection screen, or via a digital input. Switching to or
from manual mode is via Bumpless Transfer.
In Manual mode the Setpoint display is replaced by a -100 to 100% power output
level, labelled “Man”.

Press D or U to set the required manual power.
When using VMD control, Manual mode replaces the Setpoint display with the valve
movement status (Opening, Closing or Stopped), and is labelled “Man”.

The U key opens the valve and the D key closes the valve.
If Manual control is selected when in Cascade mode, the slave loops % power value
is shown. This is the power output fed directly to the control actuator (e.g. heaters).

NOTE: Selecting Manual Control will cause a running profile to hold

until control is returned to automatic mode.

CAUTION: Manual mode overrides the automatic control loop. It also

ignores any output power limits, valve open/close limits and the control
enable/disable setting. The operator is responsible for maintaining the
process within safe limits.

Over/Under Range & Input Fail Indications

If the process or auxiliary inputs are >5% above or below the scale max/min, the

displayed value is replaced with the word “HIGH” or “LOW”.
If a signal break is detected, the value is replaced with “OPEN”; except in Ratio

control where an open input 1 or 2 is shown as “x1-Open” or “x2-Open”.
An un-calibrated input is replaced by “ERROR”.
In OPEN or ERROR conditions, the Control Outputs go to the pre-set power value
(see Control Configuration on page 6).

CAUTION: Correct the problem causing the error condition before

continuing normal operation.

Customising Operator Mode

The user can choose to enable or disable some operator mode screens from the
Display Configuration menu (see page 6). These are: cascade mode switching;
auto/manual control selection; setpoint ramp-rate values; selecting the setpoint
source; control enable/disable; clear latched outputs; manually triggering a recording;
recorder status information and trend views – these are marked ◘ in the screen list on
page 5 to indicate that they are optional.
In addition, up to 50 configuration mode parameters can be copied into operation
mode using the PC software. Any parameters selected in this way are shown at the
end of the normal operator mode screen sequence.

NOTE: Configuration mode parameters copied into operation mode

are not pass code protected.

It is recommended that you only enable operator mode screens if they are important
for daily operation. Consider using Supervisor Mode (see section 21) for parameters
that the operator may need less often or that you want to limit access to.

4. AUTOMATIC TUNING

To automatically optimise the PID tuning (PI tuning in VMD mode) for the process, you
can use Pre-Tune, Self-Tune or Auto Pre-Tune independently for each loop.
Pre-tune performs a single start-up disturbance test. It stops running when the test
has completed. The user chooses which PID set the new tuning terms will be applied
to, and this selection does not change the selected “active PID set”. There are two
modes; Standard Pre-Tune which tests the process response half-way from the
activation point (the process value when pre-tune began running) to the current
setpoint; or Pre-Tune at Value which allows the user to specify the exact process
value at which the test will occur.

CAUTION: Consider possible process over-shoot when selecting the

value to tune at. If there is a risk of damage to the product or equipment
select a safe value.

If Auto Pre-Tune is selected, a Standard Pre-tune will attempt to run at every power
up. If Self-Tune is selected it constantly monitors the process and adjusts the tuning
when control errors occur. Auto pre-tune and self-tune apply the new tuning terms to
the current Active PID set. Auto pre-tune and self-tune are not possible with cascade.

NOTE: To pre-tune a cascade, first select “Cascade-Open” to tune the

PID set(s) on the slave. After the slave has successfully tuned,
remember to pre-tune the master/slave combination (this time select
“Cascade-Closed”). The cascade remains open until you do this.

See PID Sets & Gain Scheduling on this page and Automatic Tuning on page 5. Refer
to the Full Product Manual (from your supplier) for more about tuning.

NOTE: Automatic tuning will not engage if either proportional band is

set to On/Off control. Also, pre-tune (including and auto pre-tune
attempt) will not engage if the setpoint is ramping, a profile is running,
or the Process Variable is <5% of span from setpoint.

5. PID SETS & GAIN SCHEDULING

Up to 5 sets of PID tuning terms (primary & secondary proportional bands or on-off
differential, integral & derivative times, overlap/deadband) can be entered for each
control loop, allowing the unit to be pre-set for differing conditions. For each loop one
set can be selected as the “Active PID” set, or alternatively, if the process conditions
change significantly during use (e.g. if it is partially exothermic as the temperature
rises) Gain Scheduling can be employed.

Gain scheduling ‘bumplessly’ switches
PID sets automatically at successively
higher setpoint or process values, giving
optimal control across a wide range of
process conditions. PID set 1 is used
from the scaled input lower limit until the
“breakpoint” for set 2 is passed and that
set becomes active. Set 2 is used until
the breakpoint for Set 3 is reached etc. If
any breakpoint is set to OFF, the
subsequent PID sets are not used.

See Automatic Tuning section 4 for tuning the PID sets.

NOTE: ON/OFF control is possible with the individual PID sets but

cannot be used with gain scheduling. On/off control is replaced with
the default proportional band if gain scheduling is turned on.

6. APPLICATION SETUP

Setup Wizard

An easy Setup Wizard runs automatically at first ever power-up. Follow the wizard to
setup parameters required for basic applications. The screens/parameters marked “w”
in the Screen Sequences lists are included, see pages 5 & 6. The wizard can be run
again at any time from the main menu. An option to reset all parameters to default
(recommended) is offered when manually running the wizard.

Pre-commissioning Considerations

The next sections provide guidance for more complex applications where the wizard is
not sufficient. It is important to understand how the instrument is to be used before
commencing with the setup. Consideration must be given to the following questions:

If fitted, how will the 2nd input be used?

 One loop only (2nd input not used in this application)
 Two independent control loops.
 Valve feedback for loop 1
 A “redundant” backup for the 1st input (see section 10).
 Cascaded with the first control loop (see section 7).
 A reference input for ratio control (see section 8).

How will the instrument control the process?

 Primary only or primary & secondary control outputs (see section 12).
 Direct valve motor drive outputs (see section 11).

The table below shows the main input and control configuration settings for these
application types (see page 6 for the configuration menus).

Which outputs will be used for control, and are alarms or event outputs needed?

 Output configuration (see page 6).
 Alarms & Profile Events (see pages 5 & 6).

Where will the controller setpoint come from?

 Local setpoint(s) only, or a remote setpoint input (see page 6).
 Profile Control (see section 15).

Is Input re-configuration required:

 Analogue input calibration & scaling (see section 13).
 Digital input functions (see section 9).

Which other features are to be used?

 Data Recorder (see section 17).
 Serial Communications (see section 19).
 USB Interface (see section 16).

CAUTION: Configuration & commissioning must be completed before

proceeding to Operation Mode. It is the responsibility of the installing
engineer to ensure that the configuration is safe.

7. CASCADE CONTROL MODE

Applications with long time lags (e.g. with two or more capacities such as heated
jackets) can be difficult to control with a single control loop. The solution is to split the
process into two or more cascaded loops consisting of a Master and Slave(s) acting

on a common actuator. Ideally, the slave loop’s natural response time should be at

least 5 times faster than the master.
The master loop compares the process temperature with the desired setpoint and its
correcting variable (0 to 100% PID output) becomes the slave loops effective setpoint
(scaled to suit the process). This setpoint is compared to the slave’s process input,
and the controlling actuator is adjusted accordingly.

NOTE: Cascade control is available on models fitted with the 2nd

Universal Input. The master connects to input 1; the slave to input 2.

Example

In this example the controlling actuator is a heater, indirectly heating the product via
an oil jacket. The maximum input to the slave represents 300ºC, thus restricting the
jacket temperature. At start-up the master compares the product temperature
(ambient) to its setpoint (250ºC) and gives 100%. This sets the maximum slave
setpoint (300ºC), which is compared to the oil temperature (ambient) and the slave
requests maximum heater output.
As the oil temperature rises towards the slave setpoint, its output falls. Eventually, the
product temperature will also begin rising, at a rate dependant on the transfer lag

between the oil jacket and the product. This causes the master’s PID output to

decrease, reducing the slave setpoint. The oil temperature is reduced towards the
new slave setpoint. This continues until the system becomes balanced. The result is
quicker, smoother control with the ability to cope with changes in the load. Overshoot
is minimised and the jacket temperature is kept within acceptable limits.

Cascade Operation

Normal Cascade Operation

During operation, the master and slave are coupled together and. "Cascade" is
displayed. The master process value and setpoint are most relevant to the user. This
setpoint is directly adjustable, and the process value of the slave controller is
displayed for information only.

Cascade-Open

The cascade can be disconnected (via digital inputs or menu selection), switching
from normal operation to direct control of the slave. "Cascade-Open" is displayed.
The process is then controlled and adjusted solely by the slave controller using its
internal setpoint (displayed as SlaveSP). Switching back to Cascade is “Bumpless”.

CAUTION: The master process value is not under control when the

cascade is open, but will be affected by the slave process. The
operator is responsible for maintaining safe conditions.

Manual Mode

The controller can be put into manual mode (via digital inputs or menu selection),
bypassing the cascade to take direct control of the slave loop’s correcting variable.
Manual power is adjusted from -100 to 100%. "MAN" is displayed in manual mode.

CAUTION: Manual mode disables the cascade loop. It also ignores any

output power limits, valve open/close limits and the control
enable/disable setting. The operator is responsible for maintaining the
process within safe limits.

Cascade Tuning

The user can tune manually or use the pre-tune feature (see Automatic Tuning).

In either case the slave control loop must first be optimised on its own, followed by
the master loop in combination with the previously tuned slave.

To pre-tune a cascade:

1. Go to the Automatic Tuning menu

2. Select “Cascade-Open” to tune the PID set(s) on the slave.

3. After the slave has successfully tuned, pre-tune the master/slave combination
(this time select “Cascade-Closed”). The cascade remains open until you do this.

To manually tune a cascade:

1. Open the cascade, breaking the link from master to slave.

2. Set the slave controller setpoint manually to an appropriate value.

3. Tune the slave for relatively fast control (‘proportional only’ is often sufficient).

4. Close the cascade and tune the master/slave combination.

8. RATIO CONTROL MODE

A ratio control loop is used where the quantity of one of the material is to be controlled
in proportion to the measured quantity of a second material. The controller mixes the
materials at the desired ratio by adjusting the flow of input 1. The flow of input 2 may
be controlled separately, but is not controlled by this loop.
The process value used by the controller is therefore determined by the ratio of the
two inputs rather than being measured as one process variable.

NOTE: Ratio control is available on models fitted with the 2nd Universal

Input. Connect the Air flow to input 1 and the fuel to input 2.

Stoichiometric combustion

Below is an example of standard ratio control using stoichiometric combustion.
For optimum combustion the fuel-air ratio must be controlled. The ratio is selected so
that there are no inflammable residues in the waste gas.

It is normal in this application to display the process value and setpoint as relative
values rather than the physical ratio or absolute values. A scaling factor is set such
that the displayed value will be 1.00 at the correct stoichiometric ratio for the
application.

Inputs 1 and 2 are configured and scaled to match the attached flow meters.
In this example a 4 to 20mA signal at x1 represents 0 to 1000m3/h of airflow controlled
by a valve. The second 4 to 20mA signal at x2 represents 0 to 100m3/h of fuel oil. The
fuel flow is not affected by this control loop.
Atomizing air is fed in with the fuel oil at a constant rate ‘NO’. This must be considered
when calculating the correct fuel/air mix. Total airflow is x1 + NO.
The stoichiometric factor, SFac is entered to match the desired ratio. E.g for 10 parts
total airflow to one part fuel, SFac would be 10.

The setpoint (entered as a relative value such as 1.00) is multiplied by SFac when
calculating the control deviation. E.g. with a setpoint of 1.00 and SFac of 10 the
controller attempts to make the physical ratio 10. With a setpoint of 1.03 it would
attempt to make the ratio 10.3 for 3% excess air.

The instantaneous (controlled) process value is calculated from the physical ratio,
divided by SFac. Like the setpoint, this is displayed as relative value.
E.g. if SFac is 10, 59.5m3/h air is measured at x1, 0.5m3/h atomising air is applied at
NO and 6m3/h fuel is measured at x2, the instantaneous process value would be:

9. DIGITAL INPUTS

Digital inputs are driven to one of two states (active or inactive) by an applied voltage
signal or a contact opening/closing. They can be used for profile selection (see Digital
Input Setup sub-menu on page 6), with any remaining inputs available for functions
such as selecting setpoint sources, running a profile or driving an output on/off (the
Digital Input Specifications on page 4 lists all possible functions).

A diagnostic screen assists commissioning
and fault finding by showing the current
signal state for all digital inputs.

Slot A, C1 to C8 & Soft digital input status
( = Active, Ø = Unavailable)
Profile select bit format (BCD or Binary)
Profile selected (e.g. BCD 6 from C1-C3)

Digital inputs can be inverted to reverse

their action with an “on” input turning off.

Step thorough each input using the R
key. Press U to invert  the highlighted
input and D to un-invert . Hold R down
to skip to next screen accepting the
values shown.

Highlighted Input

Four “soft” digital inputs can be configured
by combining physical inputs, alarms &
events using Boolean logic. The input AND
selections are globally OR’d with input OR
selections, alarms & events. By using the
invert inputs function, NAND & NOR
equivalents can be created.

Soft inputs and any physical digital inputs
not allocated for profile selection can be
used to change the instrument status.
Functions include: Setpoint or Auto/man
select; control on/off; automatic tuning;
clearing latched outputs; profile control;
data recording; forcing outputs on/off or
mimicking key presses.

10. REDUNDANT INPUT

If the 2nd universal input is fitted, it can be used with a backup sensor so that if the
main sensor fails, the instrument automatically switches to the redundant sensor. In
this condition, if input 1 has a signal break alarm configured it will activate, but any
other process input or control status alarms seamlessly switch to the 2nd input. This
input continues to be used until the signal to input 1 is restored. The user may not
even be aware of the sensor fault, so signal break alarms should be configured for
both inputs to provide notification.
The redundant sensor must be of the same type, and be correctly located in the
application ready to take over if needed. If this option is selected, the 2nd input cannot
be used for other functions.

NOTE: If both signals are lost at the same time, the PV is replaced with

“OPEN” and the normal sensor break actions occur.

11. VALVE MOTOR / 3-POINT STEPPING CONTROL

When directly controlling motorised modulating valves, set the Control Mode to VMD
in configuration mode to enable the 3-point stepping Valve Motor Drive control
algorithm. This provides switched outputs to move the valve further open, or further
closed when a control deviation error is detected. If the error is reduced to zero no
further output is required until the load conditions change.

NOTE: Some modulating valves have positioning circuitry to adjust the

valve position. These need a DC linear mA or voltage output and use the

standard control algorithm (Set Control Mode to Standard).

VMD doesn’t allow On-Off Control (Prob. Band minimum is 0.5% of input span) and
usually requires PI control, where the Derivative parameter is turned OFF.

Special Wiring Considerations for Valve Motor Control

Valve Motor Drive (VMD) mode requires two identical outputs to be assigned to
position the valve. One to Open and one to Close the valve. These outputs can
be two single relays, two triacs, two SSR drivers or one dual relay, but it is
recommended to use two single relays (SPDT change-over contacts), and to
interlock the wiring as shown. This prevents both motor windings from being
driven at the same time, even under fault conditions.

CAUTION: The windings of a valve motor effectively form an

autotransformer. This causes a voltage doubling effect when power is
applied to either the Open or Close terminal, causing twice the
supplied voltage at the other terminal.

Switching actuators directly connected to the valve motor must only be used up to
half of their rated voltage. The internal relay and triac outputs are rated at 240VAC
Therefore, the maximum motor voltage when using them is therefore 120V unless
interposing relays are used. Interposing relays or other devices used to control the
valve must themselves be rated for twice the motor supply voltage.

Position Feedback

The VMD mode in this instrument uses a boundless, open-loop, algorithm. It does not
require any kind of position feedback in order to correctly control the process and can
therefore avoid problems associated with faulty feedback signals.
However, where feedback is available it can still be displayed as a percentage (0 to
100%) of the possible valve opening.
Valve Position Feedback is usually provided by means of a potentiometer
mechanically linked to the valve. The output of a related flow meter can also be used
to indicate the relative valve position. Flow meters typically have linear 0-20/4-20mA
or 0-5/0-10V signals. To display the position/flow signal the 2nd input is must be
configured for this purpose.
The input is adjusted and scaled to read 0 to 100% for valve fully closed to fully open
or for the flow rate equating to fully closed and open.

Valve Limiting

When Valve Position Indication is to be used the signal can be used by the
instrument to limit the valve movement. Valve limits can be set beyond which the
controller will not attempt to drive the valve.

CAUTION: These limits must be used with care. They are effectively

control power limits. Do not set values that prevent proper control of
the process!

12. CONTROL TYPE

The control type defines if a control loop has single (unidirectional) or dual
(bidirectional) control outputs. Single control has a primary output only. This can drive
the process in one direction (e.g. heating only, cooling only, increasing humidity etc).
Dual control has both primary and secondary outputs which can force the process to
increase or decrease (e.g. heating & cooling, humidifying & dehumidifying etc). This
selection isn’t required for VMD control which provides direct 3-point stepping control
for valves, and always has one output to increase and another to decrease the
process value (see section 11).

13. INPUT CALIBRATION & SCALING

The process inputs can be adjusted to match the characteristics of the attached
process or to remove sensor errors. For each loop, independent use of base
(unadjusted), single point offset or two point calibration strategies are possible, as is
the use of multi-point scaling for the displayed values.

CAUTION: Calibration & Scaling must be used with care. Careless

use could lead to the displayed value bearing no meaningful
relationship to the actual process variable. There is no front panel
indication of when these parameters are in use.

NOTE: These methods do not alter the internal instrument calibration.

Simply choose Base Calibration to restore normal measured values.

Re-calibration of the internal base values is possible, but should only be
attempted by qualified personnel as it overwrites the factory calibration ­refer to the Full Product Manual if this is required.

Single Point Calibration

This is a ‘zero offset’ applied to the process variable across the entire span. Positive

values are added to the reading, negative values are subtracted. It can be used if
the error is constant across the range, or the user is only interested in a single
critical value. Simply enter a value equal, but opposite to the observed error.

This example shows a positive
offset value.

E.g. if the process displays 27.8
when it should read 30, an
offset of +2.2 would correct the
displayed value to 30.
The same offset is applied to all
values, so at 100.0 the new
value would be 102.2.

Two Point Calibration

This method is used where an error is not constant across the range.
Separate offsets are applied at two points in the range to eliminate both zero and
span errors. Measure the error at a low point in the process, and again at a high
point. In the Input Calibration, enter the desired low point as the Calibration Low PV
value, and an equal, but opposite value to the observed error as the Calibration Low
Offset. Repeat this for the high point PV and calibration offset in the next screen.

This example shows the effect
of adding a positive Low Offset
and a negative High Offset.

E.g. if the process displays +0.0
at the low end, an offset of +0.5
would change the value to +0.5
A high end value of 100 with a -

1.7 offset would read 98.3.
There is a linear relationship
between the two calibration
points.

NOTE: Choose values as near as possible to the bottom and top of

your usable span to achieve maximum calibration accuracy. The
effect of any error can grow past the chosen calibration points.

Multi-point Scaling

If an input is connected to a linear signal (mA, mV or VDC), multi-point scaling can
be enabled for that input from the Input Configuration sub-menu, so that a non-linear
signal can be linearized.
The scaled input upper & lower limits define the values shown when the input is at
minimum and maximum values. Up to 15 breakpoints can scale the input vs.
displayed value between these limits.
Enter the 1st Scaling point (this is a % of the scaled input span), and the desired
display value to be shown at that input value. Next set the 2nd point and display
value, followed by the 3rd etc. Continue unit all breakpoints are used or you have
reached 100% of the input span. A breakpoint set at 100% ends the sequence
It is advisable to concentrate the break points in the area of the range with the most
non-linearity, or an area of particular importance to the application.

14. SETPOINT SOURCES

The setpoint is the target value at which the instrument attempts to maintain the
process variable. Each loop can have a Main “local” setpoint set from the keypad
and Alternate setpoint. The alternate setpoint sources can be either another local

Setpoint” or a remote setpoint (RSP), set by a mA or V DC signal fed to the auxiliary

or 2nd process input. The controller can only use one setpoint source at a time for
each loop. This is called the “Active Setpoint”.
Main/alternate setpoint selection can be made via a digital input; from Control
Configuration or if enabled in Display Configuration, an operator menu can be used
to select the setpoint.
Refer to the control configuration screen on page 6 for setpoint settings.

NOTE: In profile control mode, the selected profile provides the

active setpoint source for one or both control loops (see section 15).
Once profile control mode is exited, the selected Main or Alternate
setpoints become active again.

15. PROFILER OPTION

The Profiler (or setpoint programmer) feature allows the user to store up to 255
profile segments (each with the possibility of 2 setpoints in two-loop control), shared
between a maximum of 64 Profiles. Each profile controls the value of the setpoint(s)
over time; increasing, decreasing or holding their values as required.

NOTE: If this feature is fitted, Profiler options are added to the Main

Menu, and optionally to Operation Mode. See sections 3 & 20.

Profiler Enabling

Controllers supplied without the Profiler option can be upgraded in the field by
purchasing a licence code. To obtain the correct code you must tell your supplier the
instrument serial number – this can be found in Service & Product Information.

To enter this code, hold down the L + D keys during the power-up splash screen.
Enter the 16-character licence code in the displayed screen, then press R.

To confirm if profiling is installed, refer to Service & Product Information.

General Profile Configuration

General profile configuration settings apply to all profiles. They enable/disable profile
editing while running, and automatic starting of profiles that were setup with delay or
day & time start triggers. When disabled profiles can only be manually started, and
this is with immediate effect even if they have a delay or day & time trigger defined.
When enabled, delayed starts are possible, and if the selected profile has a day &
time trigger it will wait and then start at the time set.

Profile Header & Segment Information

Each profile has its own header information plus 1 or more segments. The header
contains the profiles name; if it is to control one or both loop; how it should start &
stop; abort/power-loss recovery actions and if it should repeat. Segments can be
ramps, dwells, steps or special segments such as holds, ends, joins or loop backs.

NOTE: Header information is only stored as the Segment creation

sequence begins. No profile is created if you exit before this point.
Segment information is stored as each segment is created, but the
profile remains invalid until an end or join segment is defined.

Following a Start Trigger, profiles can start immediately, or if enabled after a delay,
or at a specified day & time (Recorder only).

NOTE: Profiles with segments outside of the current setpoint limits will

not run, A “profile not valid” error shows.

Segments have an end of segment Target Setpoint. If the 1st segment is a Ramp-
Time, the slope needed to reach the target changes with the Starting Setpoint
value. For a Ramp-Rate segment, the time will change instead. A Dwell (or “soak”)
holds the last segments value. Step segments jump straight to the target value.
Segments in two-loop controllers control the setpoints of both loops.

NOTE: If the last segment is a Join, the join target profile will start, but

if the join target has been deleted the profile sequence will abort.

An End segment ends the profile or sequence of joined profiles.

2-Loop Profiles

If required, the setpoint of both
control loops can be maintained
when profiling. The example to
the right shows how this works.
Auto-Hold settings and target
setpoints are independent for
each loop, but the segment types
and time settings are the same.

Seg. ➀ & ➁ shows a ramp and a
dwell with the shared time base.

Independent

Setpoints

Loop 1

Loop 2

Seg. Nos

Both loops on same time-base

The ramp direction can be different (Seg. ➂), and although one loop cannot ramp
while the other dwells, a "dwell" is achieved by a ramp with its final setpoint value at

the same value as the previous segment (Seg. ➄). Similarly, if only one loop is to
Step to a new value, make the other “step” to its existing setpoint value. If you later
change the previous setpoint, you may have to change both segments.
The Loop-back feature takes both loops back to the previous segment.
Ramp-Rate segments are not possible with 2-loop profiling.

NOTE: Either loop can cause the profile to auto-hold. The profile

continues only when both loops are back within their hold bands.

Run/Hold & Hold Segments

Hold Start

Continue
Triggers

Hold Stop

Hold Segments

A Hold condition during a segment maintains the current setpoint value of both
loops. Once the hold is stopped the Ramp or Dwell continues.

NOTE: A running segment will hold if the operator or a digital input

instructs it to, during “auto-hold”, if one of the profile control loops is

disabled, if a cascade is set to “open” or if manual control is selected.

A Hold Segment maintains the value of the last 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 (Recorder only).

Loops Segments

Loop back target segment

Loop Segment

End

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, but they must not cross.

Profile Cycles & Repeat Sequences

PROFILE 4

PROFILE 31

PROFILE 7

Join (Profile 4 to Profile 31)

Join (Profile 31 to Profile 7)

A profile can be made to run itself 1 to 9999 times or continuously using the Profile
Cycles setting. A profile ending with Repeat Then End will run the entire sequence
of profiles again 1 to 9999 times or continuously.

Auto-Hold

Each segment has independent Auto-Hold settings. If used, these ensure process
and profile remain synchronised. If the process does not closely match the setpoint,
the profile can be held until it returns within bounds. The segment time is increased
by the time that the process is out of bounds. When Auto-Hold is active the profile
status is shown as Held. The user can choose to hold the profile if the process
beyond the Hold Band Above only, Below only or Band (either side of the setpoint).
2-loop profiling has individual Auto-Hold settings for the two loops. The entire profile
(i.e both loops) will be held if either process is outside of its Auto-Hold Band.

End, Abort and Power/Signal Lost Recovery

If the power is cut or the input is lost (either signal for 2-loop profiling) while a profile
is running, the instrument will use the defined Profile Recovery Method once the
signal / power returns. These options are explained below.

A

End the profile and maintain the profile value from the time the power failed.

B

End the profile and use Controller Setpoint value.

C

End the profile with the control outputs off – setpoint value display says “OFF”

D

Restart the profile again from the beginning.

E

Continue profile from the point it had reached when the power failed

On Recorder versions, option E will always be used if the power / signal is lost for
less than the Profile Recovery Time. If the power / signal is lost for more than this
time the defined Profile Recovery Method is used.

Similar options are offered for the Profile End Action taken at the normal profile
end, or for the Profile Abort Action if the profile is force to end before it is finished.
These can be defined to act in a similar manner as A, B or C above

16. THE USB INTERFACE

The USB Interface can be used to upload or download instrument settings to or
from a USB memory stick. It allows easy configuration of multiple instruments or the
transfer of settings to/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.

NOTE: If this feature is fitted, a USB Menu option is added to the Main

Menu. See USB Port information in section 20.

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.

NOTE: To speed up the disk operation, keep the number of files stored

in these folders to a minimum.

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 name already

exists, data will be overwritten

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.

The first recorder log file is named 001-0001.csv. A new file is created with the first
3 digits incremented (e.g. 002-0001.csv; 003-0001.csv etc) each time the data being
recorded is changed. The last 4 digits increment (e.g. 001-0002.csv; 001-0003.csv
etc) if the file size reaches 65535 lines, if a recording is stopped then re-started or if
there is a period of >10s without an alarm when recording from an alarm trigger.

CAUTION: During Data Transfer, normal operation carries on in the

background, but operator access to other screens is not possible.
Transfer of full memory can take up to 20 minutes. Only begin a
transfer when access (e.g. setpoint changes) will not be required.

17. DATA RECORDER

This option can record the process conditions to memory over time. It operates
independently from the Trend Views.

NOTE: If fitted, Recorder options are added to the Configuration and

Main Menus. Recorder Control can be also added to Operation Mode.
See Data Recorder information in section 20.

CAUTION: This feature includes a battery backed Real Time Clock

(RTC). Servicing and replacement of the internal lithium battery
should only be carried out by a trained technician.

The RTC also expands the profiling capabilities and allows a “calibration due”
reminder at a specified date. See page 5 for Profile Setup:, & page 6 - Input

Configuration: for the calibration reminder, and Clock Configuration for RTC settings.

Recorded Data

For each control loop, a combination of values can be recorded at each sample,
selected from: Process Variable; Maximum or Minimum PV (since the previous
sample); Setpoint; Primary Power, Secondary Power or Auxiliary Input values.
Additionally the status of Alarms and Profiler Events can be recorded, as can when
the unit is turned On/Off.

NOTE: If recorded, each alarm/event change forces an extra sample

to be recorded, reducing the remaining recording time available.

Sample rates between 1 second and 30 minutes are possible, with the data
recorded until the memory is full, or continuous First In/First Out memory overwriting
the oldest data with new. See Recorder Configuration on Page 6 for more details.

Recorder Triggers

Options for starting/stopping recordings include Manually (from the recorder menu
or a screen added to operation mode); a Digital Input; during a Running Profile;
or Record on Alarm. Any active trigger that has been configured will cause the
recorder to run. The recorder status screen has a % memory used bar graph and
icons for the active record triggers.

Manual Record ON

Digital Input ON

Profile Record ON

Alarm Record ON

Downloading Recordings

Recordings can be transferred to a memory stick using the USB Port or downloaded
to the PC software via the configuration port or serial communications if fitted.
Recordings are stored in Comma Separated format (.csv) which can be opened and
analysed with the optional PC software. The recorded data files can also be opened
directly into a spreadsheet, or imported into other software. See Section 16Error!
Reference source not found. for file information.

NOTE: Analysis with the PC software is limited to 8 analogue

channels, so only the first 8 will be displayed. The number of
recorded alarms & event channels is not limited.

Calibration Reminder

The recorders RTC allows a "calibration due reminder" to be shown if the date is
equal to or after the Calibration Reminder Date. The reminder screen persists until

the R key is pressed. If due, the reminder is shown at Power-up, and repeated
every 24hrs until the reminder date is changed.
See Input Configuration: for the calibration reminder settings.
