do not touch connections to such inputs whilst the inputs are live. With live sensors,
all cables, connections and switches for connecting the sensor must be mains rated
for use in 240V Cat II.

the temperature sensor whilst the instrument is live, it is recommended that the
shield of the temperature sensor be grounded to safety earth, as an additional
protection against electric shock.

Warning: The instrument must not be wired to a three-phase supply with an unearthed star

connection, because, under fault conditions, such a supply could rise above 240V
RMS with respect to ground, thus rendering the instrument unsafe.

Note: Safety requirements for permanently connected equipment state:

a. A switch or circuit breaker shall be included in the building installation
b. It shall be in close proximity to the equipment and within easy reach of the operator.
c. It shall be marked as the disconnecting device for the equipment.

Note: Recommended external fuse ratings are: 2A Type T 250V.

* A full definition of ‘Hazardous’ voltages appears under ‘Hazardous live’ in BS EN61010. Briefly, under nor­mal operating conditions, hazardous voltages are defined as being > 30V RMS (42.2V peak) or > 60 V dc.

1. This instrument is intended for industrial temperature and process control applications within the require­ments of the European directives on safety and EMC.

2. Installation may be carried out only by qualified personnel.

3. To prevent hands or metal tools coming into contact with parts that are electrically live the instrument
must be installed in an enclosure.

4. Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/filtering/
sealing etc. must be installed in the enclosure.

5. The mains supply fuse within the power supply is not repl a ceable. If it is susp ected tha t the fuse is fa ulty,
the manufacturer’s local service centre should be contacted for advice.

6. Whenever it is likely that protection has been impaired, the unit shall be made inoperative, and secured
against accidental operation. The manufacturer’s nearest service centre should be contacted for advice.

7. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment might be impaired.

8. The unit must be wired according to the instructions in this manual.

9. Before any other connection is made, the protective earth terminal shall be connected to a protective con­ductor. The mains (supply voltage) wiring must be terminated in such a way that, should it slip, the Earth
wire would be the last wire to become disconnected. The protective earth terminal must remain con­nected (even if the equipment is isolated from the mains supply) , if any of the I/O circuits are co nnected to
hazardous voltages*.
The protective earth connection must always be the first to be connected and the last to be disconnected.
Wiring must comply with all local wiring regulations, e.g. in the UK, the latest IEEE wiring regulations
(BS7671) and in the USA, NEC class 1 wiring methods.

10. Signal and supply voltage wiring should be kept separate from one another. Where this is impractical,
shielded cables should be used for the signal wiring.SAFETY NOTES (Cont.)

11.

The maximum continuous voltage applied between any of the following terminals must not exceed 240Vac.

1.Relay output to logic, dc or sensor input connections

2.Any connection to ground.
The ac supply must not be connected to sensor input or low-level inputs or outputs.

12. Over temperature protection: A separate over-temperature protection unit (with an independent tempera­ture sensor) should be fitted to isolate the process heating circuit should a fault condition arise.

Alarm relays within the recorder/controller do not give protection under all fault conditions/

13. In order to allow the power supply capacitors to discharge to a safe voltage, the supply must be discon­nected at least two minutes before the instrument is removed from its sleeve. The touching of the
exposed electronics of an instrument which has been removed from its sleeve should be avoided.

14. Instrument labels may be cleaned using iso-propyl alcohol, or water or water-based products. A mild
soap solution may be used to clean other exterior surfaces.

USB DEVICE PRECAUTIONS

Note: The use of U3 USB Flash drives is not recommended.

1. Precautions against electrostatic discharge should be taken when the instrument terminals are being
accessed. The USB and Ethernet connections are particularly vulnerable.

2. Ideally, the USB device should be plugged directly into the instrument, as the use of extension leads may
compromise the instrument’s ESD compliance. Where the instrument is being used in an electrically
‘noisy’ environment however, it is recommended that the user brings the USB socket to the front of the
panel using a short extension lead. This is because the USB may ‘lock up ’ or reset in noisy envir onments
and the only means of recovery is to remove the device, then re-insert it. For memory sticks, EMC-related
failure during a write operation might cause corruption of the data held on the stick. For this reason, the
data on the memory stick should be backed up before insertion and checked after removal.

3. When using a USB extension cable, a high quality scre ened cable must be used. The total length of USB
cable between the device and the USB port must not exceed 3 metres (10 ft.)

4. Most barcode readers and keyboards are not designed for use in industrial EMC environments, and their
operation in such environments may result in impaired performance of the recorder/controller.

32-BIT RESOLUTION

Floating point values are stored in IEEE 32-bit single precision format. Values which require gr eater resolution
than is available in this format are rounded up or down.

1 INTRODUCTION

This document describes the installation, operation and configuration of a paperless graphic recorder/control­ler. The instrument comes, as standard with four input channels and is equipped, for secure archiving via FTP
transfer and/or to USB memory stick.

1.1 UNPACKING THE INSTRUMENT

The instrument is despatched in a special pack, designed to give adequate protection during transit. Should
the outer box show signs of damage, it should be opened immediately, and the contents examined. If there is
evidence of damage, the instrument should not be operated and the local re presenta tive conta cted for in struc­tions. After the instrument has been removed from its packing, the packing should be examined to ensure that
all accessories and documentation have been removed. The packing should then be stored against future
transport requirements.

2 INSTALLATION

Caution: Before installation, ensure that the specified instrument supply voltage matches the

facility supply

2.1 MECHANICAL INSTALLATION

Figure 2.1.1 gives installation details.

2.1.1 Installation Procedure

2.1.2 Demounting

Warning: Before removing the supply voltage wiring, isolate the su pply voltage and secure it

against unintended operation.

1. Isolate the mains supply and secure it against accidental operation. Remove all wiring and the USB
device and Ethernet cable (if any).

2. Remove the retaining springs by unhooking them from the sides using a small flat-blade screwdriver.

3. Pull the instrument forwards out of the panel.

2.1.3 Removing the Instrument from its Sleeve

The instrument is designed to be removed from its sleeve from the front panel. However, if a USB memory stick
or the Ethernet cable is fitted then this must be remove d first.

When the instrument is shipped from the factory it is fitted with two small red clips, one in the top side of the
sleeve and the other below. These are intended as a safeguard against removal of the instrument from its
sleeve when an Ethernet cable is fitted. These clips must also be removed, using a small screwdriver, before
the instrument can be taken out of its sleeve.

Ease the latching ears (Figure 2.1) outwards and pull the controller forward.
When plugging back in ensure that the latching ears click into place to maintain the panel sealing.

2.2.2 Low Voltage Option

This option allows the use of a low voltage ac or dc 24 V supply. The specification in Appendix A gives full
details. The polarity of the dc supply connection is not important - it may be connected either way round.

2.2.3 Dual Input Option

This is a cost option, enabled on a channel-by-channel basis by means of entering the relevant password in the
‘Feature3 Pass’ field in Instrument.Security menu described in Section 4.1.6.

For each enabled channel, a pair of thermocouple, mV or mA inputs can be connected to the instrument. These
inputs are called ‘primary’ and ‘secondary’, and are terminated at the a nalogue inpu t terminals (An In1 to An In

4) as shown in ‘figure 2.2, above. The primary inputs 1 to 4 are assign ed to channels 1 to 4, as nor mal. Each
secondary input must be soft wired to a maths channel configured as Operation = ‘Copy’ if it is to b e recorded/
displayed/alarmed etc.

Note: Due to the nature of the input circuit, a large offset may appear for secondary thermocouple

inputs. This offset can be removed only by using the input adjust feature described in Sec­tion 4.1.9 Because of this offset, the dual thermocouple input option is not suitable for
AMS2750D applications

Soft wiring is described in Section 7
Maths channels are described in Section 4.5.1
Channel configuration is described in Section 4.4.1
Input adjust is carried out as described in Section 4.1.9

SAMPLE RATE

For dual input channels, both primary and secondary sample rate is reduced to 4 Hz (250ms) from the no rmal
8Hz (125ms).

SENSOR BREAK DETECTION

Input sensor break detection is not supported for secondary inputs. The internal circuit acts as a ‘pull up’ on the
secondary input which therefore saturates high in the event of a sensor break.

DUAL MILLIAMP OFFSET CORRECTION

If ‘Dual mA’ is selected as input type, then an automatic offset correction will be made, according to the shunt

value entered in channel configuration.

INPUT RANGE LIMITATION

There is no 10V range associated with the secondary input. Any input greater than +2V or less than -2V is
deemed to be ‘bad range’.

2.2.4 Modbus Master communications

The master instrument can be connected directly to up to two slaves using standard ethernet network cable
either directly (single slave only) or via a hub or switch (one or two slaves). In e ither ca se, ‘straigh t through’ or
‘crossover’ cable may be used. The cable is terminated at the RJ45 socket at the rear of the unit.

2.2.5 EtherNet/IP

The Client and Server are connected in the same way as described above for Modbus Master communications,
except that there can be only one client and one server.

3 OPERATION

On power up a default or custom splash screen appears and remains visible whilst the unit is ini­tialising. If during this process a network broadcast storm is detected, the unit stops, displaying a
network failure icon until the broadcast storm has cleared, after which the initialisation process re­sumes.

3.1 INTRODUCTION

The operator interface consists of a displa y sc re e n and fo ur pus h bu tto n s.

3.1.1 Display Screen

The display screen is used both to display channel information (in one of a number of display modes), and to
display the various configuration screens which allow the user to setup the recorder to display the required
channels, to set up alarms and so on. Display modes are described in Section 3.4 below; configuration is de­scribed in Section 4.

In display mode, the screen is split horizontally into three areas (figure 3.1.1)

1. a faceplate giving channel details.

2. the main display screen showing channel traces etc.

3. the status area, displaying instrument name, the current tim e and date and any system icons.

Figure 3.1.1 Display mode screen (vertical trend)

In configuration mode, the entire display screen is devoted to the selected configuration menu.

3.1.2 Navigation Pushbuttons

Figure 3.1.2 Top level menu (Engineer level access)

There are four navigation buttons, called ‘Page’, ‘Scroll’, ‘Lower’ and ‘Raise’ located below the screen. The gen­eral properties of these buttons are descri bed in the remainder of this section, but some have additional, context
sensitive functions, which, for the sake of clarity are not described here but in the relevant sections (e.g. ‘Mes­sage summary’) of the manual.

Navigation Pushbuttons (Cont.)

PAGE BUTTON

From any non-configuration page, pressing this push button causes the top level menu (figure 3.1.2) to appear.
The figure shows the menu for a user logged in with ‘Engineer’ level access. Other access levels may have
fewer menu items.

Within configuration pages, the Scroll button can be used as an enter key to select lower menu levels. In such
cases the page button is used to reverse this action, moving the user up one menu level per operation.

SCROLL BUTTON

From trending pages, operation of the scro ll push-button scrolls through the ch annels enabled in the group. The
Faceplate cycling ‘Off’ selection can be used to keep a particular channel permanently displaye d, and the scroll
pushbuttons can then be used to select channels manually.

In configuration pages, the scroll key operates as an ‘enter’ key to enter the next menu level associated with
the highlighted item. Once the lowest menu level is reached, operation of the scroll key allows the valu e of the
selected item to be edited by the relevant means (for example, the raise/lower keys, or a keyboard entry).

The ‘Page’ key is used to move the user back up the menu structure, until the top level menu is reached, wh en
the scroll key can be used again to return to the Home page.

The scroll button is also used to initiate user wiring as described in Section 7.

RAISE/LOWER BUTTONS

Within trending displays, the Raise and Lower keys ca n be used to scroll through the enabled display modes in
the sequence: vertical trend, horizontal trend, vertical bargraph, horizontal bargraph, numeric, vertical trend...
and so on.

Within configuration pages, these pushbuttons act as cursor keys, allowing, for example, the user to highlight
menu items for selection using the scroll button, and in many cases allowing the u ser to select one from a num­ber of alternative values within menu items. These keys are also used to navigate through the virtual keyboards
(Section 3.6) and number pads used to enter text or numeric strings.

3.1.3 On Screen Help

The top level configuration menu includes contextual help te xt on the righ t-hand half of the screen. Mostly this
text fits within on screen height. Where this is not the case, the text can be moved up or down the screen by
holding the Page button operated whilst using the up and down arrows to move the text.

The down arrow moves the text upwards on the screen; the up arrow moves it downwards.

3.2 PROCESS VARIABLE DISPLAY

As discussed above, the operator interface consists of a display screen and associated push buttons. The
display screen shows process variables in one of a number of formats, or operational details (notes or alarm
history for example), or configuration details for use in settin g up the recorder to produce th e required displa ys
and history formats. The remainder of section three discusses the process variable displays, alarm displays
and so on; configuration details are to be found in Section 4.

Note: Some of the items below can be selected for use only by users with a suitable permission

level as set up in the ‘Instrument’ ‘Security’ menu described in Section 4.1.6.

Figure 3.2 below, depicts a typical trend display an d give s de ta ils of the var io us ar ea s of the dis pla y page .

Figure 3.2 shows a vertical trend page. Operating the Raise/Lower push-buttons allows the user to scroll
through the other display modes: Horizontal trend, Vertical bargraph, horizontal bargraph, numeric, vertical
trend... and so on. All these display modes are described in Section 3.4, below.

A display mode can also be selected from the Top leve l menu ‘Go To View’ item which appears when the ‘Pag e’
key is operated.

The scroll button can be used to scroll through the p oints in the gr oup, o verriding the ‘F aceplate Cyclin g’ on or
off selection

3.2.1 Alarm Icons

The alarm icons shown below appear in some display modes. The icons on a channel faceplate show the status
of that channel’s alarm(s), as follows:

Icon is flashing alarm is active but unacknowledged or it is an Auto alar m which is no longer a ctive

Icon steadily illuminated the alarm is active and has been acknowledged.

Alarm thresholds and deviation alarm bars app ear for hori zontal and ver tical tren d modes. For deviation bars,
the bar stretches from (Reference - Deviation) to (Reference + Deviation). Vertical and Horizontal bargraph
modes display only absolute alarm symbols.

CHANNEL ALARM

This indicator appears if any channel (including channels not in the display group) is in an alarm state. The
symbol is illuminated continuously if all alarms are acknowledged or flashes if any one or more alarms is
unacknowledged. Alarms are acknowledged from the Root menu ‘Alarm summary’ item as described in Section

3.3.3 or in the Channel configuration area (Section 4.4.3) if the user’s access permission is appropriate.

USB

This icon appears whenever a memory stick (max. capacity 8GB) or other supported USB device (Se ction 8) is
plugged into the USB port at the rear of the recorder.

When data transfer is in progress between the instrument and the memor y stick, the icon changes to a ‘busy’
version.

Caution: The Memory stick must not be removed while archiving

(demand or automatic) is in progress, as to do so may
irreparably damage the file system of the memory stick,
rendering it unusable. It is recommended that all archiving be
suspended before the memory stick is removed.

mode is fully discussed in Section 3.5.

3.3.5 Faceplate Cycling on/off

For the purposes of this document the channel whose fac eplate is current­ly displayed and whose ‘pen’ symbol is visible is called the ‘Active’ channel.

By default, the recorder scrolls through all the channels in the display group, with each channel becoming the
active channel in turn. This top level menu ‘Faceplate Cycling’ item allows the user to inhibit this scrolling action
such that the currently active channel remains active permanently, or until a manual scroll is performed using
the scroll button (or until Faceplate Cycling is re-enabled).

‘Faceplate Cycling’ is highlighted by using the up/down arrow buttons. Once highlighted, the status can be
changed from ‘On’ to ‘Off’ or vice-versa using the scroll button. Operation of the ‘Page’ button returns th e user
to the trend display.

3.3.6 Operator Notes

This area allows up to 10 notes to be created when logged in as Engineer, usin g either the text entry techniques
described in Section 3.6, or ‘iTools’ described in Section 6. Once logged out, operating the scroll button whilst
a note is highlighted calls a selection box allowing the user either to send that note to the chart, or to write a
Custom Note.

CUSTOM NOTE

The Custom Note is written using the text entry tech niques described in Section 3.6. Once the note is complete,
operation of the page button calls a confirmation display. The down ar row is used to h igh light ‘Yes’, and whe n
the scroll key is then operated, the message is sent to the chart. This custom message is not retained for further
use, so if it is required on a regular basis, it is suggested that one of the Operator Notes 1 to 10 be configured
(Engineer access level required) so that it may be used instead.

Note: Each note can contain up to 100 characters

This allows a user, with a high enough access level, to archive a selected portion of the reco rder history, eith er
to a ‘memory stick’ plugged into the USB port at the rear of the recorder ( Local Archiving), or to a pc, by means
of the FTP protocol (Remote Archiving). The archived data remains in the flash memory of the instrument.
When the flash memory is full, new data causes the oldest file(s) to be discarded.

The up and down arrow keys are used to navigate to the required field.

Suspend Schedule When set to ‘Yes’, automatic (scheduled) archiving is stopped, once the transfer of the

current file is complete. Suspend Schedule must be set to ‘No’ again, to restart the sus­pended archive. Suspend can be used to allow the memory stick to be removed and re­fitted safely.

Cancel All When set to ‘Yes’, this cancels USB archiving activity immediately, or cancels FTP archiv-

ing once transfer of the current file (if any) is complete.

Last Archive Shows the date and time at which the last archive (demand or automatic) was attempted.

If a demand archive is requested, or is in operation when an a utomatic archive is triggered,
the automatic archive takes precedence.

Demand Archiving (Cont.)
FTP SERVER ARCHIVING

This allows the archiving of recorder files to a remote computer via the RJ45 type connector at the rear of the
recorder, either directly or via a network.

In order to carry out a successful transfer:

1. Details of the remote host must be entered in the Network.Archive area of configuration (Section 4.2.2).

2. The remote computer must be set up as an FTP server. Help from the user’s IT department may be nec­essary in order to achieve this. Appendix C, Section C2 to this manual suggests one way, using Filezilla.

3. The remote computer must also be set up to respond to ‘pings’. This is because the instru ment pings the
host whilst establishing connection, and if it does not receive a response the archive attempt fails.

When accessing files using Microsoft® Internet Explorer, the address (URL) field can be in one of two formats:

1. ftp://<instrument IP address>. This allows a user to log in as the anonymous user (if the recorder has any
account with the user name set to ‘anonymous’ with a blank password.

2. ftp://<user name>:<password>@<instrument IP address> to log in as a specific user.

For IE5 users, Microsoft® Internet Explorer displays, by default, history files only. To quit the history folder,
either uncheck the Tools/Internet Options/Advanced/Browsing/’Enable folder view for FTP sites’ option, or
check the Tools/Internet Options/Advanced/Browsing/’Use Web based FTP’ option.

REVIEW SOFTWARE

‘Review’ is a proprietary software package which allows the user to extract ‘archive’ data from one or more suit­able instruments* and to present this data on a host computer, a s if on a ch art, or as a spre adsheet. The ho st
computer must be set up as an ftp server (see Appendix C section C2 for a description of one way of doing this).

As described in the Review help system, ‘Review’ allows the user to set up a regular transfer of data (u sing ftp)
from connected instruments into a database on the pc, and then from this database to the chart or spreadsheet.
The chart/spreadsheet can be configured to includ e one or more ‘points’ from o ne or all connected instruments
(where a ‘point’ is an umbrella term for channel, totaliser, counter etc.).

It is also possible to archive instrument history files to a memory stick, Compact Flash card etc. (depending on
instrument type) and to use this to transfer the data to the pc.

Each type of instrument has its own remote user name and password configuration - for this instrument, the
user name and password are both ‘history.

*Suitable instruments are connected instruments, the archive files of which have the suffix ‘.uhh’.

3.4 DISPLAY MODES

The following subsections describe the various display modes availab le to the user. By default, the ‘Home’ dis­play mode is ‘Vertical Trend’, but this can be edited as a part of ‘Instrument.Display’ configuration. This config­uration area also allows the user to disable one or more display modes should they not be required.

The current display mode can be chosen either by using the top level menu ‘Go to View’ item or, from any dis­play mode, by scrolling through the enabled modes using the up or down arrow button.

Details of the various display modes are to be found in the following subsections:

3.4.1 Vertical Trend

In this mode, channel values are traced as though on a chart rolling downwards (i.e with the latest data at the
top). The chart speed, and the number of major divisions are configured in the ‘Group.Trend’ area of configu­ration (Section 4.3.1). By default, the chart background is black, but this can be changed to white or grey in the
‘Instrument’ ‘Display’ area of configuration (Section 4.1.3).

One of the channels is said to be the ‘current’ or ‘scale’ channel. This channel is identified by its pen icon being
displayed, and by the channel descriptor, dynamic value and its scale being displayed on a ‘faceplate’ across
the width of the display, above the chart.

Each channel in the Group becomes the ‘current’ channel in turn, for app roximately five seconds -i.e. the chan­nels are cycled through, starting with the lowest numbered channel. Once the final channel in the Group has
ben displayed for five seconds, the first channel is returned-to and the process repeats. This scrolling behaviour
can be enabled/disabled from the top level menu ‘Faceplate Cycling (Off)’ item described in Section 3.3.5.

The scroll button can be used to cycle through th e channels manually in both Faceplate cycle on and off modes.
Use of the up arrow button causes the next ena bled display mode to be entered (default = horizontal trend).
The page key calls the top level menu.

3.4.2 Horizontal Trend mode

This view is similar to the vertical trend mode described in section 3.4.1 above, except that the traces are pro­duced horizontally rather than vertically. Initially, as each channel appears, its scale appears at the left edge o f
the display (as shown below), but in order to show the maximum amount of trend data , the scale is overwritten
after a few seconds.

Note: Timestamps appear to the right of the gridline to which they relate

Use of the up arrow button causes the next enabled display mode to be entered (default = vertical bargraph).
Use of the page key calls the top level menu.

3.4.3 Vertical Bargraph mode

This display mode shows the channel values as a histogram. Absolute alarm threshold va lues appear as lines
across the bars, grey if the alarm is not triggered; red if the alarm is triggere d. Alarm symbols appear for active
alarms.

Bargraph widths for four to six channels divide the width of the display screen e qually between them. For o ne
and two channels, the width is fixed, and the bars are centred on the screen. Figure 3.4.3 shows some exam­ples (not to the same scale).

Use of the up arrow button causes the next enabled display mode to be entered (default = horizontal ba rgraph).
Use of the page key calls the top level menu.

3.4.8 Cascade Display Mode

This display mode appears only if ’Cascade’ has been enabled in the Instr ument.Displa y area of configura tion
Section 4.1.3). See also Advanced Loop configuration (Section 4.7).

Figure 3.4.8a Cascade display mode

Operating the scroll button highlights the Master ‘Mode’ field. Operating the scroll button again, enters edit
mode allowing the user to use the up/down arrow buttons to scroll through the available modes. Once the re­quired mode appears, a further operation of the scroll button confirms the entry and quits edit mode.

Once out of edit mode, the down arrow key can be used to select Master ‘SP1’, Slave ‘SP’ and Slav e ‘Man OP’.
The Mode selected determines how many of these items are editable by the operator.

Mode Cascade: The master loop is in auto mode and provides the slave setpoint. Changing

modes causes the slave to switch to the local slave setpoint.
Slave: A simple single loop controlling with a local setpoint.
Manual: Provides a single manual % power output.

SP1 Setpoint 1 is the primary setpoint of the controller. If the controller is in automatic control

mode, then the difference between the setpoint and the process variable (PV) is continu­ously monitored by the control algorithm. The difference between the two is used to pro­duce an output calculated to bring the PV to the setpoint as quickly as possible without
causing overshoot.

SP The slave setpoint, either local (Manual or Slave mode) in which case it can be edited, or

supplied by the master loop (Cascade mode), in which case it is not editable.

Man.OP The percentage output power to be applied when in Manual mode (100% = full on; 0% =

off).

Note: The default loop names (‘Master’ and ‘Slave’) can be replaced by user-entered strings of up to

10 characters in Advanced Loop Setup configuration (Section 4.7.2).

Program name This is the name of the loaded program. If the program has been modified since being

saved, an asterisk (*) appears after the name . Default background colour shown. This col­our changes to that assigned to the input channel when this is configured.

Segment name This is the name of the current segment. If not named in Segment configuration, then the

segment number appears instead.

Program status At the top right hand corner of the display, this can be any one of the following:

The program is running (or ran last time) without any PV ‘Alarm’ events or user inter­vention.

The user has intervened in the running of the program, by placing it in ‘hold’ or ‘r eset’,
or by advancing a segment, or by adjusting a duration, target setpoint, ramp rate or time­to-target value.

A PV ‘Alarm’ Event has activated. A PV ‘Alarm’ Event is an absolute high/low or a
deviation alarm on the PV input.

There is no program loaded, or if a program is loaded, it has not yet run.

Program edit This icon appears for users with appropriate access perm issions, to in dicate that set-

point programs can be configured (as described in Program edit, below).

Segment type For single channel displays, this indicates the type of segment currently being run:

Dwell. The segment value remains constant for the duration of the dwell period.
End (dwell). Displayed on completion of the program. The segme nt value remain s

at the final value until reset
End (reset). Displayed on completion of the program. The program resets.
Ramp. The segment value ramps at a fixed rate or over a fixed period to the Target

setpoint. Ramp up icon shown; ramp down is similar but inverted.
Step. The segment value switches immediately to the new Target setpoint. Step

down shown; step up similar but inverted.
Wait. The segment value remains constant until the wait criteria are satisfied.

HOLDBACK

Holdback pauses the program (freezes the Programmer setpoint (PSP) and the time remaining parameters) if
the difference between the Process value (PV) and the PSP exceeds a user-specified amount (Holdback
value). The program remains paused until the PV returns to within th e specified deviation.
In ramp or step segments, holdback indicates that the PV is laggi ng the SP by mor e than the specified amount
and that the program is waiting for the process to catch up. In a dwell segment, holdback is used to guaran tee
that a work piece stays at set-point within a specified tolerance for the specified dwell duration

Type Select a segment type. Default is ‘End’.

Ramp. For any program, Ramp segments can be either ‘Ramp Rate’ segments or ‘Ramp

Time’ segments according to the ‘Ramp Style’ setting described above. See also ‘Ch1(2)

Time’ or ‘Ch1(2) Rate’, below.

Dwell. The setpoint is maintained at its current value for the period defi ne d in ‘Dur a tion’

(see below).

Step. A step segment allows a step change to be entered for the target set-points Ch1

TSP and Ch2 TSP.

Wait. A wait segment causes the program to wait for a certain event to occur befo re con-

tinuing. See ‘Wait For’, below.

Go Back. A Go Back segment allows a specifiable number of iterations to be performed

of a group of segments. This could be used, for example, to cycle an entire program by

having a Go Back segment immediately before the end segment an d specifying segment

1 as the ‘Go Back To’ point. Setting ’Cycles’ to ‘Continuous’ causes the program to loop

indefinitely, until interrupted by the user. ‘Nested’ loop s are not permitted i.e. ‘Go Back’ is

not available as a segment type for segments inside an existing GoBack loop.

End. The final segment of a program allows the user to select ‘Dwell’ or ‘Reset’ as the ac-

tion to be taken at the end of the program (see ‘End Type’, below)
Ch1(2) TSP Target setpoint. The value that Ramp or Step segments seek to attain, for channel 1(2).
Ch1(2) Rate For Ramp Rate segments, this specifies the speed at which the process value ramps to-

wards the target, for Channel 1(2). The ramp units (per second, per minute, per hour) are

set in Ch1(2) ramp units described above.
Ch1(2) Time For Ramp Time segments, this allows the user to specify the time to be taken by the seg-

ment for the process value to reach the target.
Duration For Dwell segments, this allows the entry of the time for which the segment dwells.
Go Back To For ‘Go Back’ segments, this defines the number of the segment to which the program is

to return.
Cycles The number of times the ‘Go Back’ instruction is to be carried out. If set to ‘Continuous’,

the program continues until the user intervenes to stop it.
End Type Allows the user to select the action to be taken at the end of the program:

Dwell: the set-point is maintained indefinitely and event outputs remain at their configured

state.

Reset: the set-point reverts to the value used by the control loop before the program was

started and the event outputs return to their default states.
Wait For Digital High: Wait segments can be configured to wait for ‘Wait Digital’ to go ‘high’ before

allowing the program to continue.

Analog 1(2): The segment waits for ‘Wait Analog1(2) to meet an Absolute High or Low,

or Deviation High or Low condition before allowing the program to continue.

Analog Both: As Analog 1(2) above, but waits for both Channels’ conditions to be true

before continuing.

Note: ‘Wait Digital’, Wait Analog 1’ and ‘Wait Analog 2’ parameters are configured in the

Programmer.Set Up menu described in Section 4.8.3.

Ch1 Wait Select ‘Abs High’, ‘Abs Low’, ‘Dev High’ or ‘Dev Low’ as the wait criterion for channel 1.

Appears only if ‘Wait For’ (above) is set to ‘Analog 1’ or ‘Analog Both’.
Ch2 Wait Select ‘Abs High’, ‘Abs Low’, ‘Dev High’ or ‘Dev Low’ as the wait criterion for channel 2.

Appears only if ‘Wait For’ (above) is set to ‘Analog 2’ or ‘Analog Both’.

BCD Switch

PROGRAM LOAD VIA A PROGRAM NUMBER

This feature has been added to firmware versions V5.00 and above.
To allow a program (stored as a file) to be loaded, either via a BCD switch, wir ed to a set of digital inputs, or via

a single comms transaction, it is necessary to prefix the progam name with a program number in the range 01
to 99. For example, 01kiln1.uipz, 01furnace.uipz, 02kiln2.uipz, 03kiln3.uipz etc. The program name can con­sist of up to 18 characters. Note that program numbers 1 to 9 must be entered as 01 to 09 otherwise they will
not be recognised by the switch or via comms.

On value change of the program number, the first program file with the prefixed number in the instrument’s in­ternal User drive (listed lexographically) will be loaded. In the above example if program 01 is selected, 01fur­nace.uipz will be loaded, 01kiln1.uipz will not be loaded using the BCD switch or through comms. It can, of
course, be loaded manually.

If no program number is prefixed it is not po ssible to load the progra m via the BCD switch or via comms. It is,
however, still possible to load the program by selecting the file as described in the previous section.

Note: When a BCD switch is turned from its current value to another value, intermediate switch

positions may be seen on the inputs of the BCD function block and could potentially be used
by subsequent blocks wired from the BCD input. A Settle Time parameter has been intro­duced which will in effect filter out these intermediate values by applying a time in which the
inputs can settle before their converted decimal value is seen on the output parameters of the
block. The Settle Time can be set from 0-10seconds with a default of 0s i.e. no filtering as in
previous firmware versions. The BCD block is described in Section 4.19.

OPERATION

A sterilising cycle cannot be initiated whilst the unit is in Configuration (Engineer) mode.
A steriliser cycle is started by setting its relevant ‘Start’ input to ‘Yes’ for the duration of the cycle. The cycle

waits (status ‘Waiting’) until input 1 reaches its setpoint, at which point the cycle enters the equilibration period
(status ‘Equilibration’), and remains there until all the configured inputs are valid. The cycle then enters the ster­ilising period and stays in this mode until the sterilising period has expired (status ‘Passed’) or until one of the
inputs becomes invalid (status ’Failed’) for longer than its configured ‘Failure Dwell’ time.

There are four input status beacons near the top right hand corner of the display, one for each input.
During equilibration, the beacons are flashing red for inputs that have not attained the Target setpoint, and go

value The beacons revert to red if input falls below* the target setpoint.

During sterilisation, the beacons go red for any input whose value rises above Band High or falls below* setpoint
for a duration exceeding the configured ‘Failure Dwell’ period.

APPLICATION DETAILS

Figure 3.4.10c shows a typical steriliser application, with temperature and pressure signals from the sterilisation
chamber being applied directly to the rear terminals of the controller/recorder, and control signals connected
from the controller to both the chamber and the controller/recorder.

Analogue inputs 1 to 3 receive signals from temperature transducers ( typically thermocouples) within the cham­ber. These inputs are internally connected to channels 1 to 3 respectively, allowing transducer type, ranges,
alarms etc. to be configured (Section 4.4). Inputs are assumed to be degrees Celsius*.

The pressure transducer is connected to channel 4 and can be configured in the same way. The input is as­sumed to be in milliBar. Other pressure inputs should be converted using virtual channels*.

PV1 to PV4 in the Steriliser configuration is software wired (Section 7) to Ch 1 to Ch4.

Start cycle input and the ‘Running Output’ and ‘Passed Output’ signals are software wired to suitable DIO ter­minals, for connection to the Controller.

TEST CYCLES

A ‘Test’ cycle is initiated by initiating a 121°C cycle and a 134°C cycle simultaneously. A test cycle allows the
user to check actual performance against expected performance.

Figure 3.4.10c Typical steriliser application

Note: For Fahrenheit inputs, use one virtual channel to subtract 32, and a second to divide the

result by 1.8 (where 32 and 1.8 can be configured as user values). Sim ilar techniques should
be used to convert pressure input units if necessary.

Steriliser Display Mode (Cont.)

F0 is a means of calculating ‘equivalent time at sterilising temperature’ for temperatures below, at and above
sterilizing temperature, using the equation below.

Where:
Sterilisation time Depends on the application, typically 15 minutes at Ts = 121°C
Temp The value of the temperature measuring input.
Ts Desired Sterilising temperature
Z Temperature interval representing a factor-of-10 reduction in killing efficiency. Z = 10 for

steam sterilising (F

), or Z=20 for dry heat sterilising (FH). Z = 10 for thermal disinfection

0

(A0).
To ensure that steriliser loads which contain materials with different thermal inertias are thoroughly sterilised, a

number of sensors are located withing the load. The F va lue sh ould be calculated using the sen sor clo sest to
that part of the load which has the highest thermal inertia. For maximum accuracy, the temperature sensor
should be calibrated and the input adjust function used to compensate for any inaccuracy found.

F0 calculation examples

For all the examples following, the following are assumed: Sterilisation time = 15 minutes; Sterilisation target
temperature =121°C and Z = 10.

1. For an actual sterilising temperature of 111°C

Which means that 15 minutes at 111°C is equivalent to 1.5 minutes at 121°C

2. For a sterilising temperature of 121°C

Which means that the sterilising temperature is ideal (by definition)

3. For a sterilising temperature of 124°C

Which means that 15 minutes at 124°C is equivalent to nearly 30 minutes at 121°C.

Normally sterilising temperatures would not remain constant at temperatures below or above the target value,
so the above equations are illustrative only of the facts:

1 Temperatures below the target have some killing efficacy
2 Temperatures above the target value have a greater killing efficiency, so that the sterilising time can be

reduced.

In order to calculate the value dynamically, the instrument uses the equation:

PV is not visible unless that channel is enabled (i.e. it is not ‘Off’).

PARAMETER SELECTION

1. Open iTools and scan for the instrument, (see Section 6).

2. Once the instrument has been found, stop the scan. When th e in strume nt has synchronise d, click on the
‘Access’ button near the top of the display to set the unit into configuration mode (a password may be
required).

3. Click on the ‘+’ sign to the left of the Instrument folder in the tree list (left-most pane) to expand the folder.
Double-click on ‘Promote List’, to display the Promote list in the main pane. The list contains 20 entries, 1
to 10 being for parameters, 11 to 20 being available to the user to add descriptors for parameters 1 to 10
respectively.

4. Expand further folders, as necessary, to access the required parameters, and click-drag these parame­ters into the promote list. Enter a descriptor for the parameter if the default is not as required. As each
parameter is dragged into the list, it appears in the Promote list.

5. If the parameters are modified at the operator interface, the changes are reflected in iTools, and vice-
versa.

6. Once all the parameters have been added, it is re commen ded that the Access bu tton be used to quit con­figuration mode, as otherwise it will not subsequently be possible to quit from the operator interface.

The list of parameters can be scrolled through
using the up/down arrows. Values being read by
the master are read only, but the user may enter
values for parameters being written by the mas­ter, by highlighting the relevant item and using
the scroll key to enter edit mode.
The use of the Page key causes a return to be

3.4.12 Modbus Master display mode

This display mode consists of two pages, as shown below.

Page one opens by default and shows the first eight paramete rs being read from (left pointing arro w) or written
to (right pointing arrow) the relevant slave. These items are configured in the Mod bus Master configuration de­scribed in Section 4.9. Hidden parameters may be viewed by operating the scroll key, then using the arrow
keys to scroll through the list. A green arrow means that the item may be edited by the user when logged in.

A pair of animated indicators in the top left-hand corner of the screen show the conne ction status of the
two possible slaves. A green moving ‘streak’ indicates that successful communications are bein g carried
out. A red flashing circle indicates that there is a break in the transmission line or that the slave is switched
off. A grey, non-animated display indicates that that slave has not yet been configured as a part of the
communications link (i.e it is ‘off line’).

A ‘traffic light’ indicator appears to the right of each p arameter. Green indicates that the parameter is being read
from or written to successfully. Orange indicates that a write of the value is pending. Red indicates that there
is an error and that no value is currently being read or written; the value displayed is the last good value read
or written depending on whether the data item is a read or write. If the indicator is black, the parameter is ‘off’.

Operation of the scroll key highlights the page symbol in the top right-hand corner of the screen, and a further
operation of the scroll key calls page two to the screen.

Page two contains the IP address of the Modbus master and of an y slaves connected to it, together with some
diagnostic information, as described in ‘PING DETAILS’ below.

PING DETAILS

The ‘Ping...’ field of the first slave is highlighted by default. As shown above, the down (or up) arrow can be
used to highlight the ‘Ping...’ field of the other slave instead.

Once the relevant ‘Ping...’ field is highlighted, the scroll key can be used to enter edit mode and the up/down
arrow key used to select ‘Start’. A further operation of the scroll key initiates the ‘Ping’ and if this is successful,
a green indicator appears alongside the field (and the text re turns to ‘Ping...’). If the Ping is unsuccessful, then
the indicator is coloured red.

The up or down arrow can now be used to retu rn to slave 1, or the page key can be used to re turn to the previous
parameter display page.

As shown in the figure above, some diagnostic information is given. This includes the total number of success­ful attempts that the master has made to communicate with the relevant slave, and the total number of failed
attempts. Fuller diagnostic details are to be found in the Modbus Master Communications configuration de­scription (Section 4.9)

Ethernet/IP Display Mode (Cont.)

If the EtherNet/IP option has been ordered and enabled, the nanodac can be con figured as either a client (m as­ter) or a server (slave) (see Section 4.10). The client and se rver displa ys are iden tical exce pt that the configu­ration area of the client display is more extensive than that of the server display.

Figure 3.4.13a, above shows a typical set of display pages for an EtherNet/IP client.

CONFIGURATION OF IMPLICIT INPUT/OUTPUT TABLES

Configuration of the input and output tables is carried out via iTools drag and drop only by:
a. Entering the parameters to be read by the clie nt into th e se rve r outp ut table.
b Entering the destination parameter into the equivalent location in the client input table.
c. Entering the parameters to be written by the client into the client output table.
d Entering the destination parameter into the equivalent location in the server input tab le.
The example in figure 3.4.13b attempts to show this (using the nanodac as the client) in graphical form, using

just a few parameters (there can be up to 50 in each table)

Note: 1.Channel values from the Server can be ‘wired’ into nanodac Virtual channel inputs (as

shown above) so that they can be traced and/or recorded. In such cases the virtual
channel ‘Operation’ must be set to ‘Copy’ (see Section 4.5.1).

CONNECTION STATUS INDICATOR

A circular status indicator appears in a number of the EtherNet/IP display pages. This indicator can indicate the
following states:

Note: 2.Inputs and outputs would normally be given suitable descriptors (e.g. ‘Reset timer’ instead

of ‘Channel.1.Alarm1’).

Green rotating ‘flash’: the instrument is on line and at least one CIP connection is established.
Green flashing circle: the instrument is on line but no CIP connections have been established.
Red flashing circle: there is a break in the physical conne ctio n be tween the client a nd the server, or the

remote unit is switched off or is initialising.

Ethernet/IP Display Mode (Cont.)

Adding parameters to the input and output tables can be achieved only through the proprietary software pack­age ‘iTools’, running on a pc. It cannot be configured through the user interface. The following descrip tion as­sumes that the user is familiar with ‘iTools’. Section 6 of this manual shows how to set up an iTools link to the
unit and the iTools on-line help system and its pdf version (HA028838) should be referred-to as necessary.

Note: the client/server and the pc must all be on the same network.

Once iTools has started up and the ‘Scan’ process has ‘found’ the relevant instru ment,
the scan process should be stopped and the instrument (s) allowed to synchronise.
(The scan may be left to run its course, but the speed at which iTools operates is re­duced for the duration of the scan process.)

EXAMPLE

To add Loop 2 Setpoint 2 to Output 4 of the Client Output table.
In the example shown below, the instruments have both synchronised, and the

‘Access’ tool button clicked-on for both instruments to set them into configuration
mode.

With the client selected, expand the EtherNet/IP folder in the Browse list, then
double-click on the ‘ImplicitOutputs’ folder.

Locate and expand the Loop 2 SP folder in the Browse window, and click-drag
SP2 to ‘Output 4’ and release.

An alternative to the click-drag technique is to r ight click on the require d output (five in the example below), and
select ‘Edit Wire...’ from the context menu that appears. A browse window pops up, allowing the user to navi­gate to the required parameter. This technique can be used both on p reviously empty inputs or outputs and o n
those previously filled.

Figure 3.4.13d Context menu details

EXPLICIT DATA

As shown in table 3.4.13, when configured as a server, there is only one explicit ap plication object, and that has
the class ID= A2 (162 decimal). The instance ID is the Modbus address of the parameter and the Attribute is
always = 1. Explicit service codes hex10 (decimal 16) and 0E (14) are both supported, for writing and reading
single attributes respectively.

Table 3.4.13 Explicit data specification

When configured as a client, two separate connections are available allowing the user to produ ce two independ­ent explicit read or write messages to different server devices.

Figure 3.4.13e below, shows an example of how to configure an explicit message request. The instance ID and
the data type are taken from the server manufacturer’s data. In this example a read request is configured to
determine the Group recording status of a nanodac server, and it can be seen from table 5.3 that the decimal
modbus address for this parameter is 4150 and the data type is int16. It is this address which is used as the
instance ID.

Once all the information has been entered, the read is requested by setting ‘Send’ to ‘Yes’. The Data field
changes to ‘3’ for this example and from table 5.3 it can be se en that the recording status is ‘Recording enabled’.

Note: The nanodac supports only 16 bit data types for reading and writing of explicit messages.

USING TAGS

When acting as servers, many PLCs present their data in a tag format instead of implicit data format. For this
reason, when the client is configured as ‘Client (Tags)’, (Section 4.10) 30 input and 30 output tags become avail­able to the user via iTools (figure 3.4.13f).

This allows tag names to be typed in, input tags 1 to 30 being associated with implicit inputs 1to 30 respectively
and output tags 1 to 30 being associated with implicit outputs 1to 30 respectively.

Figure 3.4.13f iTools display showing input tags.

In the example above, the value of the parameter with the tag ‘Channel 1’ will be written to implicit input 1.

Note: 1. Most PLCs have a data buffer limit of 500 Bytes. The total number of bytes being used is

given by the equation: Total number of data bytes = (tag length + 10) × the number of
requested tags.

Note: 2. Input data direction is always to the nanodac:

in server mode input data is written to the nanodac from the client
in client mode, input data is read by the nanodac from the server device.

Note: 3. Output data direction is always from the nanodac:

in server mode output data is written to the client from the nanodac
in client mode, output data is read by the server from the nanodac.

1. Use the up/down arrows to highlight the item to be edited.

2. When highlighted (orange background), operate the scroll button. The highlighted text turns black.

3. Use the up and down arrow keys to scroll to the required va lue for th e fie ld, then oper ate th e scro ll butto n
again. The text goes white.

4. Repeat the above editing process for all the remaining items which are to be edited.

5. Use the up/down keys to select ‘Yes’. The ‘Search for’ window closes, and the history display jumps to
the selected time and date.

Note: 1. If no history exists for the selected time and/or date ‘No History Available’ is displayed.
Note: 2. The time and date format and Daylight Savings Time (DST) effects are as set in the

‘Locale’ area of Instrument configuration. See Section 4.1.2 for further details.

3.6 TEXT ENTRY

The user is often required to enter text characters or num bers (when editing operator notes, for exa mple). This
is done using the pop-up keyboards which are displayed when required. When only numerals are required a
special keyboard is presented which contains only numerals.

Figure 3.6 shows the three standard keyboards, along with a ‘scan’ direction for operations of both up arrow
and down arrow keys. To change keyboards, u se the ar row pushb utto ns to high ligh t th e keybo ar d name ( ‘Nu ­meric’, ‘Symbols’ or ‘Alpha’), and then operate the scroll button.

Generally, to enter text, the required character is highlighted usin g the up and down arrows and the scroll button
is used as an ‘Enter’ key. Once text entry is complete, the Page button is used to confirm the edit (use the down
arrow to select ‘Yes’ then operate the scroll button).

Pressing and holding the scroll button and then immediately operating the up or down arrow, causes the char­acter insertion point to move to the left (down arrow) or to the right (up ar ro w) .

The user can press and hold the scroll key to display variations on certain characters (the letter ‘e’ in the figure).
Once displayed, the up and down arrows can again be used to scroll through auxiliary list, allowing capital let­ters, and characters with diacriticals (e.g. accents, umlauts, tildes, cedillas) to be selected and entered using
the scroll button.

The backarrow key is used as a back space key - i.e. it deletes the character to the left of the cursor position.
The ‘Del’ key deletes the character to the right of the cursor.

Note: Leading and trailing space characters are automatically removed from text strings

.

3.6.1 Numeric keyboard

As mentioned previously, for functions which can take only numerals, a special numeric
keyboard appears, as depicted in figure 3.6.1.

From firmware versions V3.01 and above there is an option to allow numbers to be rounded. The reason for
this is driven primarily from a control point-of-view. With truncation, it is quite likely that the PV will look as
though it never settles onto setpoint. The rounding/truncation affects the UI display and MODBUS scaled in­tegers, the underlying numbers are not affected, nor the values saved in the history files. Over MODBUS
comms, all floating point parameters that are read via scaled integer comms will take note of the configured
setting for rounding or truncating and reflect this. On the UI, ALL floating point values rendered will adhere to
the configured setting of rounding or truncating.

4.1.5 Upgrade

Caution: 1. Power must not be remove d from the unit whilst upgrade is in progress, as to do

so will cause permanent damage to the unit.

2. For USB upgrades, the memory stick must not be removed whilst upgrade is in
progress or the instrument will be permanently damaged.

This item allows the user to update the instrument firmware, either from a memory stick in the USB socket at
the rear of the unit, or via FTP transfer from a host computer. Firmware up grade files are downloaded from the
recorder manufacturer and transferred to the instrument by memory stick or by FTP transfer. Splash screens
are prepared by the user and transferred using a memory stick. The unit re starts automatically after an upgrade
or splash screen replacement.

Upgrade Select ‘Firmware (USB)’, ‘Firmware (FTP)’, ‘Bootrom (USB)’ or ‘Splash (USB)’ as the

source of the upgrade.

Server IP Address For ‘Upgrade’ = ‘Firmware (FTP)’ only, this field must contain the IP address of the pc

which is to supply the upgrade file.
Account Username For ‘Type’ = ‘Firmware (FTP)’ only, the username set up in the host ftp server
Account Password For ‘Type’ = ‘Firmware (FTP)’ only, the password set up in the host ftp server
Source Path The name of the directory from which the upgrade file is to be read. This is only the name

of the directory without any path elements (e.g. ’/’) included unless the path is ‘release/

upgrade/files’.
Initiate Select ‘Yes’ to initiate the upgrade.

CUSTOMISING THE SPLASH SCREEN

‘Splash (USB)’ allows the user to select a new image for the splash screen (i.e. the screen that appears at power
up or restart). When ‘Initiate’ is set to ‘Yes’, the instrument searches the USB device for a file called
‘splash.bmp’ located in the ‘release’ folder. If such a file is found, it is loaded, and the instrument re-starts with
the new image as the ‘splash’ screen. If no file is found , the request is ignored. If the image is not of the correct
type or size, the instrument re-starts with the default splash screen.

The original splash screen is included on the ‘tools’ DVD, so that it can be restored if required.
Rules:

1. This feature is available only with Bootrom versions 2.0 and above.

2. The file must be located in a folder called ‘release’ and the file name must be ‘splash.bmp’.

3. The image must be 320 x 240; 24-bit resolution.

4. The image must be in bitmap (suffix.bmp) format.

5. The image may not exceed 256kB.

Feature Pass This is a password supplied by the manufacturer to enable the software options (e.g.

Loop, Zirconia block, Toolkit blocks etc.). When applying for this code, the manufacturer
will require the instrument’s MAC address (Network.Interface menu Section 4.2.1) and the
instrument’s firmware Version (Instrument.info menu - Section 4.1.4). The password is

MAC address dependent so that it cannot be used on any other instrument.
Feature2/3 Pass Similar to ‘Feature Pass’ above, but for additional features.
Comms Pass Enables/disables password security for external communications (including via iTools). If

set to ‘Enabled’, the Engineer level password will be required if an attempt is made to enter

the configuration menus from a remote pc. If set to ‘Disabled’, then access to configura-

tion can be gained over a communications link, without a password.

If enabled, then entry to configuration mode via the Instrument Mode (IM) para meter must

be completed within 5 seconds of entering the password, or the attempt will fail.

OEM SECURITY

In products that incorporate user wiring, the value of an application may lie more in the user wiring (conne cting
the function blocks together) than in the configuration of the instrument's parameters.

OEM Security allows the user to prevent the application from being cop ied either via comms (by iTools or a third
party comms package) or via the instrument's user interface.

When OEM security is enabled, users are prevented from accessing wiring (for reading or writing) from any
source (comms or user interface), and it is not possible to Load or Save the configuration of th e instrument via
iTools or by using the Save/Restore facility (Section 4.1.8).

From firmware version V5.00 onwards OEM Security is enhanced by providing an option, enabled by a new
parameter ‘Instrument.Security.OEMParamLists. This parameter is available only through iTools and allows
the OEM to:-

1. Make all parameters that are read/write in Engineer access level only, read only when the instrument is
OEM locked AND it is in Engineer access level. It is possible for the OEM to select up to 100 parameters
which are to remain read/write in Engineer access level.

2. Make up to 100 parameters that are read/write in Su pervisor acce ss level, read o nly when the instrument
is OEM locked.

Examples of how to set up OEM security are given in the iTools Section 6.6.10.

4.1.8 Save/Restore

This allows the user to save and/or restore instrument clone configurations to a memory stick inserted into the
USB connector at the rear of the unit. The format of the saved/restored files is iTools clone files (*.uic)

Selecting ‘Restore’ presents a list of clone files in the configured directory on the USB device. (In the example
below, the file is located in the basic usb0 directory - it has not been saved to a particular configuration directo­ry.)

When ‘Save’ is selected, the virtual keyboard must be used to enter the filename. If the file already exists on
the USB device, a warning appears offering ‘Cancel’ or ‘Overwrite’ alternatives.

Note: 1. The ability to save and restore is disabled if OEM security is enabled.
Note: 2. Configuration save/restore is available only when the unit is logged into at ‘Engineer’

access level.

Note: 3. During USB cloning (USB save/restore), the priority of modbus slave comms is lowered.

This allows the save/restore process to complete in a minimal time (around 60 seconds).
During this period, modbus slave comms response times will be extended and may result
in the master device timing-out.

Figure 4.1.8 Save/Restore display

Operation Select ‘Save’ or ‘Restore’. Use the up/down arrow keys to highlight the required .UIC file,

then use the scroll key to initiate the operation.

Status Shows the status of the operation, as fo llow s:

Inactive: Neither saving or restoring a clone file has occurred since the last time the in­strument was power cycled.

Complete: Indicates that the cloning process has completed.
Restoring: Restore operation is currently in progress.
Saving: A clone file is currently being saved.
Cold started: A power-cycle of the product occurred whilst a Restore operation was

in progress. The product configuration is unr eliable and has been rese t to factory default.

The ‘Restoring’ and ‘Saving’ status text is accompanied by an animated d isplay (circling green ‘flash’) to indicate
that the operation is in progress.

4.1.9 Input adjust

Note: 1. Input adjust cannot be applied to input channels with input type of ‘Digital’, ‘Test’ or ‘Off’.
Note: 2. Input adjustments can be carried out only by users logged in as ‘Engineer’ (see Section

3.3.8).

Note: 3. The instrument must be powered for a sufficient time (e.g. 30 minutes) for it to reach ther-

mal equilibrium before an input adjust is performed.

This facility allows the user to compensate for tolerance errors etc. The technique used is to select those chan­nels to which adjust is to be applied, then for each channel to:

a apply a known low level signal (at or close to the low input range value) to the relevant input. When the

recorder reading is steady, press ‘Apply’.

b. apply a known high level signal (at, or close to, th e high inpu t range valu e) to the relevant inp ut. When the

recorder reading is steady, press ‘Apply’.

If ‘IP Type’ = ‘Fixed’, the user may enter an IP address (IPV4 dot notation). This would
normally be supplied by the user’s IT department, or from the Network supervisor.

If ‘IP Type’ = ‘Fixed’, this sets a range of IP addresses that can be accessed. Normally
supplied by the user’s IT department, or from the Network supervisor.

Gateway Read only if ‘IP Type’ = ‘DHCP’.

If ‘IP Type’ = ‘Fixed’ this allows the user to enter a gateway address for use when the unit
is to communicate outside the local network. Normally supplied by the user’s IT depart­ment, or from the Network supervisor.

SNTP Enable Select ‘Yes’ to allow time synchronisation from a Simple Network Time Protocol (SNTP)

server to be enabled. When enabled the instrument time is updated every 15 minutes.
SNTP always works using UTC/GMT. Time zones are handled separa te ly.

SNTP is a protocol that allows clients on a TCP/IP network to synchronise the instrument
clock with that of a server - port number 123. nanodac can act only as a client.

Servers such as Microsoft ‘TimeServ’ cannot be used with the nanodac beca use they are
not SNTP servers.

SNTP Server The IP address of the SNTP Server. This only appears if the SNTP server is enabled.

If ‘IP Type’ is set to ‘DHCP’, the SNTP Server address is automatically assigned. Although
this address can be altered it will be overwritte n once the instrument is power cycle d. The
SNTP address should only be entered manually if ‘IP Type’ is set to ‘Fixed’.

For a description of SNTP alarms see Section 3.2.2.

4.2.2 Archiving

This area of configuration is used to set up the parameters for use during unattended archiving. Some of the
fields appear only if other fields are set to a particular value. For example, the CSV fields appear only if ‘File
Format’ is set to ‘CSV’ or to ‘Both’.

The archived data is not removed from the flash memory of the instrument. When the flash memory is full, new
data causes the oldest file(s) to be discarded.

Note: For remote archiving, the host computer must be se t up to respond to ‘pings’. This is because

the nano pings the host whilst establishing connection, and if it does not receive a response
the archive attempt fails.

Rate Allows the user to specify the frequency at which the contents of the Flash memory are

archived to the USB port or, via FTP, to a pc. Scrollable settings are:
None: Automatic archiving is disabled. Any archiving must be initiated by the user

using Demand Archiving, as described in Section 3.3.7.
Hourly: Archive occurs on the hour, every hour.
Daily: Archive initiated at 00:00* each day
Weekly: Archive is initiated at midnight* every Sunday
Monthly: Archive is initiated at 00:00* on the 1st of every month.
Automatic: The recorder selects the least frequent of the above archive periods which is

guaranteed not to lose data as a result of the in ternal flash memory’s ru nning
out of space.

Note: * Archive times are not adjusted for daylight saving time (DST). Thus, if the archive is set to

‘Daily’, ‘Weekly’ or ‘Monthly’, then during summer time, the archive will be triggered an hour
late (i.e at 01:00 hours instead of midnight).

Destination Select ‘FTP Server’ for archive to a remote pc, or ‘USB’ to archive to the USB port device.
File format Select ‘Binary (UHH)’ ‘CSV’ or ‘Both’.

Binary (UHH):

A proprietary format used by the instrument that needs other software (e.g. Re­view’, to interpret the data before it can be presen ted in spreadsh eets etc. Bina ry
files have the extension ‘.uhh’.

CSV: This format is a standard open-file format for numeric data. A simple ASCII-based

format, it is readable by a wide range of pc applications as well as being suitable for
direct import into many commercial databases. CSV files have the extension ‘.csv’.

Both: Archiving includes both .uhh and .csv files.

Note: .CSV is ASCII based and cannot interpret Unicode characte rs. For this reason, some charac-

ters available to the user will not be displayed correctly in .csv files.

CSV Values Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then process

values are included in the file (see figure 4.2.2b for details).

CSV Messages Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then messages

are included in the file (see figure 4.2.2b for details).

CSV Headers Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then Header

details are included in the file (see figure 4.2.2b for details).

CSV Headings Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then column

headers are included in the file (see figure 4.2.2b for details).

CSV Date Format Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. Allows ‘Text’ or ‘Spreadsheet’ to be

selected. Text causes a time/date to appear in the spreadsheet. ‘Spreadsheet Nu’
displays the number of days since December 30th 1899. The decimal part of the number
represents the latest six hours. For example: DDD--- --DD.25 represents 06:00 hours and
DDD--- --DD.5 represents 12:00 hours. Spreadsheet Numeric format is more easily
interpreted than ‘Text’ by some spreadsheet applications.

CSV Tab Del Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’.

CSV (Comma Separated Variables) does not always use commas as separators. For
example, in some countries the decimal point is represented by a full stop (period), whilst
in others a comma is used. In order to avoid confusion between a comma as a decimal
point and a comma as a separator, a different separator can be used. This field allows
the ‘tab’ character (^t) to be used instead of a comma.

On Media Full For ‘Destination’ = ‘USB’ only, this allows the user to select ‘Overwrite’ or ‘Stop’ as the

action to be taken when the memory stick is full. ‘Overwrite’ causes the oldest data to be
discarded from the memory stick to make room for newer data. ‘Stop’ inhibits archiving
activity.

4.3 GROUP CONFIGURATION

Group configuration is separated into two areas, one which defines trending characteristics (for display chan­nels) the other defining the recording characteristics for saving data to the Flash memory ready for archiving.

4.3.1 Group Trend configuration

This allows the user to define which points are to be trace d on the disp lay and at what interval , and also allows
the number of chart divisions to be set up. Figure 4.3.1 shows a typical configuration page.

Note: The background chart colour is set up as a part of Instrument Display configuration (Section

4.1.3)

Figure 4.3.1 Group Trend Configuration

Descriptor Allows the user to enter a descriptor (20 characters max.) for the group.
Interval The trending interval which defines how much data appears on one screen height or width.

A number of discrete intervals can be chosen between 0.125 seconds to 1 hour. The se­lection should be made according to how much detail is required, and how much data is
to be visible on the screen.

Major Divisions Allows the user to select the number of divisions into which the scale is divided and how

many gridlines are displayed. Setting the value to 1 results in just the zero and full scale
values appearing. Setting the value to 10 (the maximum) results in a scale with zero, full
scale and nine intermediate values appearing, with associated grid lines.

Point1 to Point6 Allows the user to select which channels and virtual channels are to be traced. The max-

imum number of traces is six.

4.4.1 Channel Main

This section describes all possible menu items, but it should be noted that some items are context dependent
(e.g. Cold Junction settings appear only for Type = ‘Thermocouple’).

Channels one to four in the configuration relate to An In 1 (terminals 1I, 1+ and 1-) to An In 4 ( terminals 4I, 4+
and 4-) respectively - see figure 2.2.

Page 84

Note: For the sake of completeness, the figure above shows all possible fields, even though

many are mutually exclusive. For example, ‘Test signal’ appears only when ‘Test’ is
selected as Type. It would never appear when Type = thermocouple (as shown). Simi­larly, ‘Shunt’ would appear only for Type = mA.

Descriptor Allows a (20 character max.) descriptor to be entered for the channel. Some thought

should be given to ensure that the descriptor is mea nin gf ul be ca us e in som e disp lay

appear as ‘Furnace 1 a’ and thus be indistinguishable from one another, except in

background colour.
PV Read only. Displays the current value of the channel.
Status Read only. Shows the channel status as one of: ‘Good’, ‘Channel Off’, ‘Over range’,

‘Under range’, ‘HW error’, ‘Ranging’, ‘HW (capability) exceeded’.
PV2 Read only. For dual inputs only, displays the current value of the secondary input.

described in Section 4.1.9.
IP Adjust State2 As ‘IP Adjust State’, above but for secondary channels.
Resolution Allows the number of decimal places to be defined for the channel. Valid entries a re zero

to six.
Units Allows a units string of up to five characters to be entered.
Type Allows the user to select an input type for the channel. Available selections are: ‘Off’,

‘Thermocouple’, ‘mV’, ‘V’, ‘mA’, ‘RTD’, ‘Digital’, ‘Test’ or ‘Ohms’. If the Dual Input option

is fitted, Dual mV, Dual mA, Dual T/C (if enabled) are also available.

Note: If Dual T/C is selected then it is essential that the secondary T/C input is field calibrated

using the Input Adjust procedure (Section 4.1.9)

Test signal Appears only if ‘Test’ is selected as ‘Type’. Allows either a sinusoidal or a triangular

waveform to be selected at one of a number o f cycle time s between 40 seconds a nd five

hours.
Input Low* For Type = mV, Dual mV, V, mA, Dual mA or Ohms, the lowest value of the applied signal

in electrical units.
Input High* As ‘Input Low’, but the highest value of the applied signal in electrical units.
Shunt value For mA and Dual mA input types only, this allows the value of the shunt resistor (in Ohms)

to be entered. The recorder does not validate this value - it is up to the user to ensure that

the value entered here matches that of the shunt resistor(s) fitted. For Dual mA input type,

both primary and secondary inputs must have independent shunts each of the same

value.
Lin type Linear, Square root, x3/2, x5/2, User Lin.

Thermocouple types (alphabetical order): B, C, D, E, G2, J, K, L, N, R, S, T, U, NiMo/NiCo,

Offset2 The nature of the secondary input results in an offset being introduced into the process

variable value.

For mA inputs this offset is removed automatically, without user intervention.

For mV inputs the offset depends on the value of the voltage source impedance and is

equal to 199.9μV/Ω. This offset can be compensated for either by using this Offset2 pa-

rameter, or by carrying out the ‘Input Adjust’ procedure (Section 4.1.9).

For Dual T/C inputs, it is recommended that the ‘Input Adjust’ procedure be used instead

of Offset2 as the use of Offset2 results in an offset which is non-linear over the thermo-

couple range.
Input filter Damping can be used to filter out noise from slowly

changing signals so that the underlying trend can be

seen more clearly. Valid input values are between 0

and 60 seconds.

Note: Applying a filter to an input channel can affect the operation of any Rate-of-change alarms

configured to act on that channel.

CJC Type For thermocouple input types only, this allows the user to select ‘None’, ‘Internal’, ‘Exter-

nal’ or ‘Remote 1’ to ‘Remote 4’. For Dual T/C inputs, both primary and secondary inputs

use the same cold junction.

None: No Cold junction compensation applied.

‘Internal’ uses the recorder’s internal cold junction temperature measurement.

‘External’ means that the cold junction is to be maintained by the user, at a fixed, known

temperature. This temperature is entered in the ‘External CJ Temp’ field which appears

when ‘External’ is selected.

Remote 1 (2) (3) (4) means that the cold junctio n temperature is being measur ed by input

channel 1 (2) (3) (4) respectively. (This must be a different channel from that currently

being configured).
Ext. CJ Temp Appears only if CJC type is set to ‘External’, and allows the user to enter the temperature

at which the external cold junction is being maintained.
Sensor Break Type Defines whether the sensor break becomes active for circuit impedances greater than

expected.

‘Off’ disables Sensor Break detection.

Break Low: Sensor break active if measured impedance is greater than the ‘Break Low

impedance’ value given in table 4.4.1.

Break High: Sensor break active if measured impedance is greater tha n the ‘Break High

Impedance’ value given in table 4.4.1.

For mA inputs, limits are applied, such that if the process value lies outside these limits, a

sensor break is assumed to have occurred. These limits are (Input lo - 4% Span) and

(Input high + 6% Span). For example, for a 4 to 20mA signal, an input below 3.36mA or

above 20.96mA will trigger a sensor break event

Input sensor break detection is not supported for secondary inputs. The internal circuit
acts as a ‘pull up’ on the secondary in put wh ich there fore saturates high in the event of a
sensor break.

Fault Response Specifies the behaviour of the recorder if a sensor break is detected or if the input is over

driven (saturated high or low).
‘None’ means that the input drifts, with the wiring acting as an aerial.
‘Drive High’ means that the trace moves to (Scale High +10%). ‘Drive Low’ means that
the trace moves to (Scale Low -10%), where the 10% values represent 10% of (Scale High

- Scale Low).

This area allows the configuration of channel colour and span.

Figure 4.4.2a Channel Trend menu Figure 4.4.2b Colour selection

Colour Allows a colour to be specified for the channel. The Scroll key is used to enter the colour

swatch page. The up and down arrows are used to scroll through the available colours,

with each colour being enlarged for as long as it is ‘selected’. Once the required colour, is

reached, the scroll key is used again to return to the Trend Configuration.
Span Low/High Span low and high values.

Note: Trend colours and alarm settings for secondary inputs are configured in the maths channels

to which they are wired.

SPAN EXAMPLE

In an input range of 0 to 600 degrees C, the temperatur e ra nge betwee n 500 an d 600 degr ees is of most inter ­est. In such a case, Span Low is set to 500 and Span High to 600 so that the recorder trends only the required
part of the temperature range, effectively magnifying the area of interest.

Note: Trending is restricted to th e PV range (Span High - Span Low) , but the instrument ca n display

values outside this range

CHANNEL CONFIGURATION EXAMPLE

A type J thermocouple is used to measure a temperature range of 100 to 200 degrees Celsius. This thermo­couple output is transmitted to the recorder by a 4 to 20mA transmitter, for display as a value between 0 and
100%.

4.4.3 Alarm 1 menu

Allows the alarm characteristics for Alarm 1 to be configured. The figure below shows a typical configuration
page (expanded for clarity). Actual configuration parameters are context sensitive.

Figure 4.4.3 Typical alarm 1 configuration menu

Type Select an alarm type from: ‘Off’, ‘Abs. High’ (absolute high). ‘Abs. Low’ (absolute low),

‘Dev. High’ (deviation high), ‘Dev. Low’ (deviation low), ‘Dev. Band’ (deviation band), ‘Rise

ROC’ (rate-of-change: rising), ‘Fall ROC’ (rate-of-change: falling), ‘Digital High’, ‘Digital

Low’. See ‘Alarm types’, below, for definitions.
Status Read only. This shows that the alarm is Off, Active, SafeNotAcked or ActiveNotAcked.

For ‘Auto’ and ‘Manual’ alarms only, ‘SafeNotAcked’ means that the alarm trigger source

has returned to a non-alarm state, but the alarm is still active because it has not been ac-

knowledged. Similarly, ‘ActiveNotAcked’ means that the source is still active and the

alarm has not been acknowledged. Always shows ‘Off’ when the alarm is inhibited (see

below).

Threshold For absolute alarms only, this is the trip po int for th e ala rm. Fo r ab so lu te hig h alar ms , if

the threshold value is exceeded by the proces s value (PV) of this channel, th en the alarm

becomes active, and remains active until the PV falls below the value (threshold - hyster-

esis). For absolute low alarms, if the PV of this channel falls below the threshold value,

then the alarm becomes active and remains active until the PV rises above (T hre shold +

Hysteresis).
Reference For deviation alarms only, this provides a ‘centre point’ for the deviation band.

Deviation For deviation alarms only, ’Deviation’ defines the width of the deviation band, each side of

Page 89

For ‘deviation high’ alarms, the alarm becomes active if the process value (PV) rises

above the value (Reference + Deviation) and re mains active u ntil the PV falls below (Ref-

erence + Deviation - Hysteresis).

For ‘deviation low’ alarms, the alarm become s active if the process value (PV) falls below

the value (Reference - Deviation) and remains active until the PV rises above (Reference

- Deviation + Hysteresis).

For ‘deviation band’ alarms, the alarm is active whenever the process value (PV) lies out-

side the value (Reference ± Deviation) and remains active until the PV returns to within

the band, minus or plus Hysteresis as appropriate.

the Reference value, as described immediately above.

Alarm 1 Menu (Cont.)

Hysteresis For absolute and deviation alarms, this provides a means of preventing multiple alarm trig-

gering, if the process value is drifting close to the trigger value.
Amount For rate-of-change alarms only. The alarm becomes active if the process value rises

(Rise ROC) or falls (Fall ROC) by more than the specified ‘Amount’ within the time period

defined in ‘Change Time’, below. The alarm remains active until the rate of change falls

below the value (Amount/Change Time) in the relevant sense.
Change Time Settable to 1 second, 1 minute or 1 hour. See ‘Amount’ (above).
Average Time For rate-of-change alarms only. This allows an averaging period (for the process value) to

be entered to reduce nuisance trips due to signal noise, or if the rate of change is hovering

around the trip value.
Latch None: the alarm remains active until the monitored value has returned to a non alarm

state, when it becomes inactive.

Auto: The alarm remains active until the monitored value has r eturned to a non alarm state

and the alarm has been acknowledged. Acknowledgement can take place either before

or after the value has returned a non alarm state.

Manual: The alarm remains active until the monitor ed value has retu rned to a n on alar m

state and the alarm has been acknowledged. Acknowledgement is permitted only after

the value has returned a non alarm state.

Trigger: Not enunciated, this mode is used only to initiate an action de fined by user wiring

either using iTools or using the user interface.
Block Alarms with ‘Block’ set to ‘On’ are inhibited until the monitored value has entered the 'safe'

condition after a start-up. This prevents such alarms from becoming active whilst the pro-

cess is brought into control. If a latching alarm is not acknowledged then the alarm is re-

asserted (not blocked), unless the alarm’s threshold or reference value is changed, in

which case the alarm is blocked again.
Dwell Initiates a delay between the trigger source becoming active, and the alarm becoming ac-

tive. If the trigger source returns to a non alarm state before the dwell time has elapsed,

then the alarm is not triggered and the dwell timer is reset.
Acknowledge Select ‘yes’ to acknowledge the alarm. Display returns to ‘No’.
Active Read only. Shows the status of the alarm as ‘Yes’ if it is active , or No, if inactiv e. The ac-

tive/inactive state depends on the Latch type (above) and acknowledgment status of the

alarm. Always shows ‘No’ if the alarm is inbited (below).
Inactive As for ‘Active’ above, but shows ‘Yes’ if the alar m in inactive and ‘No’ if the alarm is active.

Always shows ‘Yes’ if the alarm is inbited (below).
N.acknowledged As for ‘Active’ above but shows ‘Yes’ for as long as the alarm is unacknowledged, and ‘No’

as soon as it is acknowledged. Always shows ‘No’ if the alarm is inbited (below).
Acknowledgement Fleetingly goes ‘Yes’ on alarm acknowledgement, and then returns to ‘No’.
Inhibit When ‘Inhibit’ is enabled, (tick symbol), the alarm is inhibited. Status is set to ‘Off’; ‘Active’

and ‘N.acknowledged’ are set to ‘No’, and ‘Inactive’ is set to ‘Yes’. If the alarm is active

when inhibit is enabled, then it becomes inactive until inhibit is disabled, when its status

depends on its configuration. Similarly if the alarm tr igger becomes active when the alarm

is inhibited, the alarm remains ‘off’ until inhibit is disab led, when its status dep ends on its

configuration.

As above for Alarm 1 menu.

Note: The parameters ‘Acknowledge’, ‘Active’, ‘Inactive’, ‘N(ot) Acknowledged’ and, ‘Acknowledge-

ment’ can all be ‘wired’ to other parameters, so, for example, a relay can be made to operate
whilst the alarm is inactive or whilst it is active or on acknowledgement etc. by wiring the rele­vant parameter to the relay’s ‘PV’ input. See Section 7 for details of user wiring.
