3. Cascade
3.1. PRINCIPLE OF CASCADE CONTROL
When cascade control is fitted, the Load Loop in the Nanodac senses the temperature of the
workload, and the Element Loop in the Nanodac senses the element temperature. Depending on
the oven or furnace model, the Load Thermocouple may be in a fixed position, or may be movable.
The Element Thermocouple is fixed in a predetermined position near the heating elements
If movable, the Load Thermocouple should be placed as near as possible to the work to be heated.
The Load Loop communicates with the Element Loop, calling for heat according to the load
temperature and the current program or setpoint. The Element Loop regulates the heat according
to element temperature and the requests from the Load Loop.
The element temperature could, in principle, vary between the furnace or oven maximum and
minimum, regardless of the working temperature of the load. In practice, the cascade control
system is configured to limit the element temperature to a band around the load temperature,
typically of ±500 C of the setpoint temperature.
The Load Loop is always accessible to the operator. The Element Loop may or may not be located
out of sight inside the control compartment. If the Element Loop is visible to the operator, the
display may be disregarded.
In a three-zone furnace for which the “three zone cascade” option has been ordered there are
three Element Controllers, all receiving the same control instructions from the Load Controller
3.2. OPERATION
The operator may ignore all the complications of the system, and program the Load Loop
according to the standard instructions for that controller. Home display is top view (Load Loop)
bottom view (Element loop). By pressing page, separate views of load and element loops will
show.
The Element Loop should never be adjusted. Note that the elements usually run at a higher
temperature than the load.
Because the details of the customer’s cascade application (in particular the nature of the load) are
generally not known, the feed forward parameter (Cascade Trim) is made easily accessible on the
cascade trim page. (Refer to instrument operating instructions). Its default setting is ±500 C. If
overshoot of the load temperature occurs – often a problem at low temperatures – then Cascade
Trim can be reduced in order to limit the amount of overshoot. If Cascade Trim is reduced too
much, however, the load may not reach the desired temperature. If the load does not reach the
desired temperature or is slow in the final stages, Cascade Trim can be increased: a maximum of
750 C is suggested.
When attempting to control at very low temperatures it can become a problem to achieve stable
control because of excessive power being supplied during heating. The available power can be
limited using the power limit parameter OP.Hi, and make a note of the original settings before
adjusting. The manual for the furnace or oven may also list standard settings for this parameter.
The parameter is normally set to 100% and contact Carbolite Engineering if this value needs to be
amended.
3.3. CAUTION
If the Load Thermocouple is removable, leave it in the furnace or oven chamber
whenever possible.
Operating with the Cascade Control active and with the Load Thermocouple in
an unheated position (such as lying on the work bench) may cause the furnace
or oven to heat up to its maximum temperature, wasting power and possibly
shortening element life.
5 MC27 –EN–1.04
nanodac™
3.4. OVER-TEMPERATURE CONTROL
Where over-temperature control is fitted, it normally protects against failure of the control system or
of a component such as a power control relay. The over-temperature controller must be set at a level
higher than the greatest element temperature, typically 15°C above maximum.
If the working temperature is less than the maximum temperature, then it may be possible to set the
over-temperature limit as follows:
Working Temperature + Cascade trim high (eg 50) +15°C
Example: for working at 800°C in a 1200°C furnace, the over-temperature limit could be set to
800+50+15=865°C.

4. 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.
4.1 INTRODUCTION
The operator interface consists of a display screen and four push buttons.
4.1.1 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 4.4 below;
configuration is described in Section 5
In display mode, the screen is split horizontally into three areas (figure 1.1.1)
1. a faceplate giving channel details.
2. the main display screen showing channel traces etc.
3. the status area, displaying instrument name, the current time and date and any system icons.
Figure 1.1.1 Display mode screen (vertical trend)
In configuration mode, the entire display screen is devoted to the selected configuration menu.
4.1.2 Navigation Pushbuttons
7 MC27 –EN–1.04
There are four navigation buttons, called ‘Page’, ‘Scroll’, ‘Lower’ and ‘Raise’ located below the screen. The
general properties of these buttons are described 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 1.1.2) 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 scroll push-button scrolls through the channels enabled in the
group. The Faceplate cycling ‘Off’ selection can be used to keep a particular channel permanently
displayed, 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
value 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,
when 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 can 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 user to select
one from a number of alternative values within menu items. These keys are also used to navigate through
the virtual keyboards and number pads used to enter text or numeric strings.
4.1.3 On Screen Help
The top level configuration menu includes contextual help text on the right-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.

4.2 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 setting up the recorder to produce the
required displays and history formats. The remainder of section four discusses the process variable
displays, alarm displays and so on; configuration details are to be found in Section 5.
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’.
Figure 1.2 below, depicts a typical trend display and gives details of the various areas of the display page.
Figure 1.2 Typical display screen (Vertical trend)
Figure 1.2 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 4.4, below.
A display mode can also be selected from the Top level menu ‘Go To View’ item which appears when the
‘Page’ key is operated.
The scroll button can be used to scroll through the points in the group, overriding the ‘Faceplate Cycling’
on or off selection
4.2.1 Alarm Icons
Note:
Trigger alarms do not display threshold marks or bars, or faceplate symbols
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 alarm which is no longer
active but which has not been acknowledged
Icon steadily illuminated the alarm is active and has been acknowledged.
Alarm thresholds and deviation alarm bars appear for horizontal and vertical trend modes. For deviation
bars, the bar stretches from (Reference - Deviation) to (Reference + Deviation). Vertical and Horizontal
bargraph modes display only absolute alarm symbols.

DISPLAY MODE SELECTION
Use the up/down arrow buttons to highlight the required display
mode. Once the required display mode is highlighted, operation of
the scroll button causes the recorder to leave the ‘Go to View’ menu
and to display channel values in the selected mode. See Section 4.4
for a description of the various display modes.
Alternatively the up and down arrow buttons can be used from any of
the display modes to cycle through the available modes in the order
listed in the figure.

4.3.4 History
This top level menu item allows the user to switch from real-time
trending to review mode, where channel values, messages, alarm
triggers etc. can be viewed back as far as the last significant
con.figuration change. History mode is discussed in Section 4.5
4.3.5 Faceplate Cycling on/off
For the purposes of this document the channel whose faceplate 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
the user to the trend display.
4.3.6 Operator Notes
This area allows up to 10 notes to be created when logged in as Engineer, using either the text entry
techniques described in Section 4.6, 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 techniques described in Section 4.6. Once the note is
complete, operation of the page button calls a confirmation display. The down arrow is used to highlight
‘Yes’, and when 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.
4.3.7 Demand Archiving
This allows a user, with a high enough access level, to archive a selected portion of the recorder history,
either 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.

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
5.1.2).
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 instrument 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, as if on a chart, or as a
spreadsheet. The host 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 (using
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 include one or more ‘points’ from one 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’.
4.3.8 Login
Login allows the user to enter a password in order to gain access to areas of the unit’s configuration which
are not available when the user is logged out.
LOGGED OUT ACCESS LEVEL
Logged out mode allows the user to select viewing mode, to view history, to view alarms, to toggle
faceplate cycling on and off, to send notes, to suspend/resume USB archiving and to access the login
process.
OPERATOR ACCESS LEVEL
In addition to the logged out features, Operator access level allows the user to acknowledge alarms, to
edit notes and to perform demand archive operations.
By default, no password is required in order to enter Operator level, but a password can be set either at
Supervisor level or at Engineer level. (See section 1)

required to enter Supervisor level, but a password can be set in the Instrument area of configuration,
either at Supervisor level or at Engineer level. (See section 1)
ENGINEER ACCESS LEVEL
This allows full access to all areas of the recorder configuration. The default password is 100, but this can
be edited in the Instrument area of configuration (See section 1).
Note: recording is stopped for as long as the user is logged in at Engineer level,
even if the recorder is not being configured. This is indicated by the Record icon
at the bottom left corner of the process value display screen being replaced by
the Configuration (wrench) icon.
LOGIN PROCEDURE
From the top level menu, use the up or down arrow keys as often as necessary in order to highlight
‘Login’, and then operate the Scroll key to produce the ‘Access Logged out’ display.
Note: this procedure describes how to login to an access level with a password associated with it.
For non-password protected logins, the user needs only to select the required access level, and
press the scroll key.

4.4 DISPLAY MODES
The following subsections describe the various display modes available 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:
4.4.1 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 (5.2.1).
Figure 1.4 Vertical trend mode display elements
MC27 –EN– 1.04 22
nanodac™
By default, after a few seconds, the
‘chart’ expands leftwards to hide the
scale.
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 approximately five seconds -i.e. the
channels are cycled through, starting with the lowest numbered channel. Once the final channel in the
Group has been 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 4.3.5
.
The scroll button can be used to cycle through the channels manually in both Faceplate cycle on and off
modes.
Use of the up arrow button causes the next enabled display mode to be entered (default = horizontal
trend).
The page key calls the top level menu.
4.4.2 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 of the display (as shown below), but in order to show the maximum amount of trend data, the scale
is overwritten after a few seconds.
Figure 1.4.2 Horizontal trend display mode
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.
4.4.3 Vertical Bargraph mode
This display mode shows the channel values as a histogram. Absolute alarm threshold values appear as
lines across the bars, grey if the alarm is not triggered; red if the alarm is triggered. Alarm symbols appear
for active alarms.
Bargraph widths for four to six channels divide the width of the display screen equally between them. For
one and two channels, the width is fixed, and the bars are centred on the screen. Figure1.4.3 shows some
examples (not to the same scale).

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 Slave ‘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.
