STARTING A PROGRAM
To start a program running:
1.3
PUTTING A PROGRAM IN HOLD
A program can be put in Hold (i.e. frozen) at any time whilst it is running. The program
setpoint will stay at its value at the instant the program entered Hold until the
program is released (see Subsection 1.4) or aborted (see Subsection 1.5). To put a
program in hold, momentarily press the RUN key. The RUN indicator will flash whilst
the program is in hold.
1.4
RELEASING A PROGRAM FROM HOLD
To release a program currently in Hold, momentarily press the RUN key. The RUN
indicator will then go ON continuously.
1-2
1.5
ABORTING A PROGRAM
To abort the current-running (or held) program, hold down the RUN key for 5
seconds. The program will be aborted, the RUN indicator will go OFF and the
normal Controller functions will be resumed.
NOTE: When a program is aborted, the instrument returns to the Controller
setpont value. If a program is successfully completed, the Controller setpoint is
automatically set to the final setpoint value of the program. If it is desired to
restore the initial Controller setpoint value after the program is completed,
theis value should be used as the program's Final Setpoint Value.

1.7
RaPID CONTROL FEATURE
The RaPID control feature may be used when extra fast responses and minimum
overshoot are required. The RaPID feature works best when PID terms are well-tuned;
therefore, it is recommended that the Pre-Tune feature (see Subsection 1.8) is run
before the RaPID feature is engaged.
To dis-engage RaPID control, use the same key actions. NOTE: The RaPID feature
cannot be engaged if Proportional Band 1 or Proportional Band 2 is set to 0.
1.8
PRE-TUNE FEATURE
This facility may be used to provide initial tuning of the Controller’s PID parameters.
Pre-Tune may be engaged (and subsequently dis-engaged) as follows:
1-4
NOTE: The Pre-Tune facility will not engage if (a) a program is currently running,
(b) the process variable is within 5% of input span of the setpoint, or (c) an
erroneous key sequence is used. Pre-Tune is a single-shot process which
automatically dis-engages itself when completed.
1.9
ENGAGING BOTH PRE-TUNE AND RaPID FEATURES
The Pre-Tune and RaPID features can be
engaged in one key action sequence
(see right). Pre-Tune will operate first. When
it is completed it will dis-engage itself and
the RaPID feature will then operate
automatically.

INSTALLATION
2.1
UNPACKING PROCEDURE
1. Remove the Controller from its packing. The Controller is supplied
with a panel gasket and push-fit fixing strap. Retain the packing for
future use, should it be necessary to transport the Controller to a
different site or to return it to the supplier for repair/testing.
2. Examine the delivered items for damage or deficiencies. If any is
found, notify the carrier immediately.
2.2
PANEL-MOUNTING THE
CONTROLLER
The panel on which the Controller is to be
mounted must be rigid and may be up to 6.0mm
(0.25 inches) thick. The cut-out required for a
single Controller is as shown in Figure 2-1.
45mm +0.5 -0.0
Several controllers may be installed in a single
cut-out, side-by-side. For n Controllers mounted
side-by-side, the width of the cut-out would be:
(48n - 4) millimetres or (3.78n - 0.16) inches.
Figure 2-1
Cut-out Dimensions
The Controller Programmer is 110mm deep (measured from the rear face of the front
panel). The front panel is 48mm high and 48mm wide. When panel-mounted, the
front panel projects 10mm from the mounting panel. The main dimensions of the
Controller are shown in Figure 2-2.
Figure 2-2
Main Dimensions
2-1
The procedure to panel-mount the Controller Programmer is shown in Figure 2-3.
CAUTION: Do not remove the panel gasket, as this may result in
inadequate clamping of the instrument in the panel.
NOTE: When installing several Programmer Controllers side-by-side in
one cut-out, use the ratchets on the top/bottom faces.
Figure 2-3
Panel-Mounting the Controller Programmer
Once the Controller is installed in its mounting panel, it may be subsequently
removed from its housing, if necessary, as described in Subsection 7.1.
2.3
CONNECTIONS AND WIRING
The rear terminal connections are illustrated in Figure 2-4.
WARNING ! This instrument is designed for installation in an
enclosure which provides adequate protection aganist electric
shock. All pertinent local regulations should be rigidly observed.
Consideration should be given to prevention of access to the
rear terminals by unauthorised personnel. Disregard for these
instructions may cause injury or death!
2-2

2.3.1
Mains (Line) Input
The Controller will operate on 96 - 264V AC 50/60Hz mains (line) supply. The power
consumption is approximately 4 VA. Power should be connected via a two-pole
isolating switch (preferably situated near the equipment) and a 1A fuse.
If the Controller has relay outputs in which the contacts are to carry mains (line)
voltage, it is recommended that the relay contact mains (line) supply should be
switched and fused in a similar manner but should be separate from the Controller
mains (line) supply.
2.3.2
24V (Nominal) AC/DC Supply
The supply connections for the 24V AC/DC option of the Controller are as shown in
Figure 2-4. Power should be connected via a two-pole isolating switch and a 315mA
slow-blow (anti-surge Type T) fuse.
With the 24V AC/DC supply option fitted, these terminals will accept the following
supply voltage ranges:
24V (nominal) AC 50/60Hz 24V (nominal) DC -
2.3.3
20 - 50V
22 - 65V
Thermocouple Input
The correct type of thermocouple extension leadwire or compensating cable must
be used for the entire distance between the Controller and the thermocouple,
ensuring that the correct polarity is observed throughout. Joints in the cable should
be avoided, if possible. The Controller’s CJC facility must be enabled (normal
conditions) for this input (see Subsection 6.4).
NOTE: Do not run thermocouple cables adjacent to power-carrying
conductors. If the wiring is run in a conduit, use a separate conduit for the
thermocouple wiring. If the thermocouple is grounded, this must be done at
one point only. If the thermocouple extension lead is shielded, the shield must
be grounded at one point only.
2.3.4
RTD Inputs
The compensating lead should be connected to Terminal 4. For two-wire RTD inputs,
Terminals 4 and 5 should be linked. The extension leads should be of copper and the
resistance of the wires connecting the resistance element should not exceed 5 ohms
per lead (the leads should be of equal resistance).
2-4
2.3.5
Linear Inputs
For linear mA input ranges, connection is made to Terminals 4 and 6 in the polarity
shown in Figure 2-4. For linear mV and V ranges, connection is made to Terminals 4
and 5 in the polarity shown in Figure 2-4. For details of the linear input ranges
available, refer to Appendix A.
2.3.6
Remote Run/Hold Input
With this option fitted, Terminals 11 and 12 are used for external Run/Hold control of
the currently-selected program; this has an effect identical to that of the front panel
RUN key. These terminals may be connected to (a) the voltage-free contacts of a
switch or relay, or (b) a TTL-compatible voltage. This is an edge-sensitive input for
which the following convention has been adopted:
For TTL input, OFF = logic 1 and ON = logic 0
Fot a voltage=free input, OFF = open and ON = closed
Program control is as follows:
OFF-ON transition:
The currently-selected program will run (or will
resume running if it is currently held).
ON-OFF transition:
The currently-running program will be held.
NOTE: When this input is used, the front panel RUN key can be used
only to abort a program. Powering-up the Controller Programmer whilst
this input is ON will not cause a program to run. The RS485 Serial
Communications option and the Remote Run/Hold option are mutually
exclusive.
2.3.7
Relay Outputs
The contacts are rated at 2A resistive at 120/240V AC.
2.3.8
DC Pulse Outputs
These outputs produce a time-proportioned non-isolated DC signal (0 - 4.2V nominal
into 1kΩ minimum).
2-5
2.3.9
AC SSR Outputs
These outputs provide up to 1A AC drive with a longer lifetime than an
electromechanical relay. For further details, refer to Appendix A.
2.3.10 DC Outputs
See Appendix A.
2.3.11 RS485 Serial Communications Link
The cable used should be suitable for data transfer at the selected rate (1200, 2400,
4800 or 9600 Baud) over the required distance. Transmitters/receivers conform to the
recommendations in the EIA Standard RS485.
The “A” terminal (Terminal 11) on the Controller should be connected to the “A”
terminal on the master device; the “B” terminal (Terminal 12) on the Controller should
be connected to the “B” terminal on the master device. Where several Controllers
are connected to one master port, the master port transceiver in the active state
should be capable of driving a load of 12kΩ per Controller; the master port
transceiver in the passive state must have pull-up/pull-down resistors of sufficiently low
impedance to ensure that it remains in the quiescent state whilst supplying up to
±100µA each to the Controller transceivers in the high impedance state.
NOTE: The RS485 Serial Communications option and the Remote
Run/Hold option are mutually exclusive.

PROGRAM DEFINITION MODE CREATING/EDITING A PROGRAM
NOTE: Program editing/creation is not possible whilst any program is
running or held.
3.1
ENTRY
In Base Mode, select the required Program Number (see Subsection 1.1), then:
NOTE: If the Program Define Mode lock code has been set to 0, pressing the
SET UP key in Step 2 will give direct access to Program Define Mode; no entry
of lock code is required.
Upon entry into Program Define Mode, the first Segment Definition parameter for
Segment 1 of the selected program will be displayed.
3-1
3.2
CREATING A PROGRAM
A program is created in two steps:
1. Define the segments of your program; the parameters used depend on
what Program Mode has been configured - Rate Mode (see Subsection 3.2.2)
or Time Mode (see Subsection 3.2.3). The segment definitions determine
whether the selected segment is a Ramp Segment, a Dwell (soak) Segment or
an End Segment.
2. Set the required Program Options (see Subsection 3.2.4). These determine:
(i) The number of cycles performed by the program,
(Ii) The timebase to be used (hours/minutes or minutes/seconds)
(Iii) The width of the Guaranteed Soak Band (if enabled),
(Iv) The state of the event indicator for each segment in the program,
(v) The lock code to be used for subsequent entries into Program Define
Mode.
3.2.1
Basic Guidelines
1. The Controller Programmer may contain up to four programs.
2. Each program may comprise up to 16 segments.
3. Each segment may be:
(a) a Ramp Segment (setpoint changing at a defined rate or between
the initial value and a pre-determined final value over a defined time),
(b) a Dwell Segment (setpoint constant for a defined time,) or
(c) an End Segment (marking the end of the program).
4. A program may contain only one End Segment (the last segment in the
program).
5. If the program comprises 16 segments, Segment 16 is automatically an End
Segment.

The Guaranteed Soak Band is applicable to sOAK segments only and operates as
follows (depending on whether Guaranteed Soak has been enabled or Manual
Guaranteed Soak has been configured):

3.2.6
Segment Event Status
For every segment in a program there is an event indicator. This may be set ON or
OFF for that segment. The status for the segments in the currently-selected program
appears in the following form in the upper display:
The first display shows the current event status for Segments 1 - 8 and the second
display shows the current event status for Segments 9 - 16. Each event marker may
be set ON (Up key) or OFF (Down key) in order of segment number. Only the event
indicators for the segments in the program are displayed. If the program has less
than 16 segments (including the End Segment), the non-applicable display positions
are blank; if the program has eight segments or less, the second display is not
3-7
included.. The lower display shows the current segment number. Thus, the key
sequence to define the event markers for Segments 1 - 8 could be:
Pressing the SET UP key would then display the event markers for Segments 9 - 16
(as applicable), which could be defined in a similar manner.

CONTROLLER SET-UP MODE
In this mode, the parameters which define the operation of the controller are
defined. Controller Set-Up Mode can be entered (whether or not there is a program
currently running) as follows:
NOTES:
1. If the Controller Set-Up Mode lock code has been set to 0, pressing the SET
UP key in Step 2 will give direct access to Controller Set-Up Mode; no entry of
lock code is required.
2. If the upper display initially shows all decimal points
illuminated (see right), one or more configuration
parameters have been altered and, as a
consequence, all ControllerSet Up Mode parameters
have been automatically set to their default
values/settings. To clear this display, simply alter the value/setting of any
Controller Set Up Mode parameter.
4-1
Upon entry into Controller Set-Up Mode, the first in a sequence of controller
parameters will be displayed. The operator may then step through the parameter
sequence using the SET UP key, adjusting the setting/value of each displayed
parameter using the Up/Down keys. The parameter sequence is as follows:

MODBUS COMMUNICATIONS
5.1
INTRODUCTION
This Section specifies the MODBUS communications protocol as implemented on the
Controller Programmer.
Certain restrictions have been imposed upon this implementation:
(i) Baud rates may be set to 1200, 2400, 4800 and 9600 only
(ii) Support for multi-parameter Writes is limited to support of the Multi-word
Write Function (Number 16) but will permit writing of one parameter only per
message
(iii) The multi-parameter Read function supports a maximum of 10 parameters
in one message.
5.2
MODBUS FUNCTIONS SUPPORTED
In the following list, the original Gould MODBUS function names have been used,
followed by the JBUS names in italics, where such an equivalence exists. The
MODBUS Function number follows the names.
A
Read Coil Status (Read n Bits)
01/02
B
Read Holding Registers (Read n Words)
03/04
C
Force Single Coil (Write 1 Bit)
05
D
Preset Single Register (Write 1 Word)
06
E
Loopback Diagnostic Test
08
F
Preset Multiple Registers (Write n Words)
16
The instrument will identify itself in reply to a Read Holding Registers message which
enquires the values of parameter numbers 121 & 122, as specified in the CNOMO
documentation, and MODBUS Function 17 (Report Slave ID) will not be supported.
5-1
5.3
MESSAGE FORMATS
The first character of every message is an instrument address. The valid range of
such an address is 0 to 255. The second character is always the Function Number.
The contents of the remainder of the message depends upon the function number.
In most cases the instrument is required to reply by echoing the address and function
number, together with an echo of all or part of the message received (in the case of
a request to write a value or carry out a command) or the information requested (in
the case of a read parameter operation). Broadcast Messages (to which the
controller responds by taking some action without sending back a reply) are
supported at instrument address zero. Commands which can be broadcast are
marked with the symbol B.
Data is transmitted as eight-bit binary bytes with 1 start bit, 1 stop bit and optional
parity checking (None, Even or Odd). A message is terminated solely by a delay of
more than three character lengths at the given Baud Rate, and any character
received after such a delay is treated as a potential address at the start of a new
message.
The following individual message formats apply. Since only the RTU form of the
protocol is being supported, each message is followed by a two-byte CRC16.
Details of how the checksum must be calculated are given at the end of this section.
A.
Read Coil Status (Read n Bits)
01/02
The message sent to the controller will consist of 8 bytes, as follows:
The normal reply will echo the first two characters of the message received, and will
then contain a single-byte data byte count, which will not include itself or the CRC.
For this message, there will be one byte of data per eight bits-worth of information
requested, with the LSbit of the first data byte transmitted depicting the state of the
lowest-numbered bit required.
5-2
This function will be used largely to report controller status information, and so a bit
set to 1 indicates that the corresponding feature is currently enabled/active, and a
bit reset to 0 indicates the opposite.
If an exact multiple of eight bits is not requested, the data is padded with trailing
zeros to preserve the 8-bit format. After the data has been transmitted, the CRC16
value is sent.
B.
Read Holding Registers (Read n Words)
03/04
The message sent to the controller to obtain the value of one or more registers is an
eight-byte message as follows:
The reply sent by the controller echoes the first 2 characters received and then
contains a single-byte data byte count, the value of which does not include either
itself or the CRC value to be sent. For this message, the count equals the number of
parameters read times two. Following the byte count, that number of parameter
values are transmitted, MSB first, followed by the CRC16.
C.
Force Single Coil (Write 1 Bit)
05
B
The message received by the controller is 8 bytes long, consisting of the standard
preamble and the address of the bit to force, followed by a two-byte word whose
MSB contains the desired truth value of the bit expressed as 0xFF (TRUE) or 0x00
(FALSE).
Generally, this function will be used to control such features as Auto/Manual and
Tuning. The normal reply sent by the controller will be a byte-for-byte echo of the
message received.
5-3
D.
Preset Single Register (Write 1 Word)
06
B
The message sent to the controller consists of 8 bytes: the address and function
number as usual, the address of the parameter to be written, and the two-byte value
to which the parameter will be set, and finally the CRC16.
The normal response is to echo the message in its entirety.
E.
Loopback Diagnostic Test
08
The controller is sent an 8 byte message consisting of the usual preamble, a two-byte
diagnostic code, and two bytes of data, followed by the CRC16.
Full MODBUS support in this area is not appropriate - consequently, the only
Diagnostic Code supported is code 00. In response to the message, the controller
must echo the message received exactly.
F.
Preset Multiple Registers (Write n Words) 16
B
This message consists of eleven bytes. Only one parameter may be written at a time,
even though this function number is supported. The preamble is followed by the
address of the parameter to be written, and then a two-byte word count (always set
to 1) and a single-byte byte count (always set to 2). Finally, the value to be written is
followed by the CRC16.
The controller normally responds with a eight-byte reply, as follows:
5-4
G.
Error and Exception Responses
If the controller receives a message which contains a corrupted character (parity
check fail, framing error etc), or if the CRC16 check fails, the controller ignores the
message. If the message is otherwise syntactically flawed (e.g. the byte count or
word count is incorrect) the controller will also not reply.
However, if the controller receives a syntactically correct message which nonetheless
contains an illegal value, it will send an exception response, consisting of five bytes
as follows:
The Function Number field consists of the function number contained in the message
which caused the error, with its top bit set (i.e. function 3 becomes 0x83), and the
Exception Number is one of the codes contained in the following table:

CRC16 Calculation
This is a 16-bit cyclic redundancy checksum. It is calculated in accordance with a
formula which involves recursive division of the data by a polynomial, with the input
to each division being the remainder of the results of the previous one.
The formula specifies that input is treated as a continuous bit-stream binary number,
with the most significant bit being transmitted first. However, the transmitting device
sends the least significant bit first.
According to the formula, the dividing polynomial is 216 + 215 + 22 + 1 (Hex 18005),
but this is modified in two ways:
5-5
i. Because the bit-order is reversed, the binary pattern is reversed also,
making the MSB the rightmost bit, and
ii. Because only the remainder is of interest, the MSB (the right-most bit) may
be discarded.
This means the polynomial has the value Hex A001. The CRC algorithm is as follows:
5-6
5.4
PARAMETER NUMBERS
The parameter numbering system, in order to conform to the CNOMO standard, splits
parameters into BITS and WORDS and numbers each group independently.

NOTES:
1. If Output 2 is a relay/Solid State/SSR Drive output, it may be a control output
(COOL), an event output or an alarm output; if it is set to be a DC output, it
can only be a control output (COOL).
2. If Output 3 is a relay/SSR Drive output (it cannot be an Solid State output), it
can only be an event output or an alarm output; if it is set to be a DC output, it
can only be a recorder (i.e. re-transmitted process variable or setpoint) output.
The maximum setting available for this code is 4887. For example, the code for a
thermocouple input, DC 4 - 20mA primary output (Output 1) and relay Output 3
would be 2701.
NOTE: It is essential that this code is changed promptly whenever
there is a change to the instrument’s hardware configuration
(change of input/output type, alarm/recorder output
added/removed etc.). The instrument software depends upon this
code to ensure that the instrument operates correctly.
This code may be viewed as a Read Only display in Base Mode (see Subsection
1.11).

INTERNAL LINKS AND SWITCHES
REMOVING THE CONTROLLER PROGRAMMER FROM ITS
HOUSING
WARNING ! Before removing the instrument from its housing, ensure that
all power has been removed from the rear terminals. Disregard for
these instructions may cause injury or death!
To withdraw the instrument from its housing, simply grip the side edges of the front
panel (there is a finger grip on each edge) and pull the instrument forwards. This will
release the instrument from its rear connectors in the housing and will give access to
the instrument PCBs. Take note of the orientation of the instrument for subsequent
replacement into the housing.The positions of the PCBs in the instrument are shown in
Figure 7-1.

REMOVING/REPLACING THE OUTPUT 2/OUTPUT 3
OPTION PCBs
With the instrument removed from its housing:
1. Gently push the rear ends of the CPU PCB and Power Supply PCB apart
slightly, until the two tongues on each of the Output 2/Output 3 Option PCBs
become dis-engaged - see Figure 7-2B; The Output 2 Option PCB tongues
engage in holes in the Power Supply PCB and the Output 3 Option PCB
tongues engage in holes on the CPU PCB.
2. Carefully pull the required Option PCB (Output 2 or Output 3) from its
connector (Output 2 Option PCB is connected to the CPU PCB and Output 3
Option PCB is connected to the Power Supply PCB) - see Figure 7-2C. Note the
orientation of the PCB in preparation for its replacement.
Adjustments may now be made to the link jumpers on the CPU PCB, the Output
2/Output 3 Option PCBs (if DC output) and (if fitted) the DC Output 1 PCB. The
replacement procedure is a simple reversal of the removal procedure.
7.3
REMOVING/REPLACING THE RS485 COMMUNICATIONS
OPTION PCB OR REMOTE RUN/HOLD OPTION PCB
The RS485 Communications Option PCB or Remote Run/Hold Option PCB is mounted
on the inner surface of the Power Supply PCB and can be removed when the
instrument is removed from its housing (see Subsection 7.1) Figure 7-3 illustrates the
removal/replacement procedure. It is not necessary to remove the Output 2/Output
3 Option PCBs to perform this procedure.
7.4
REPLACING THE INSTRUMENT IN ITS HOUSING
To replace the instrument, simply align the CPU PCB and Power Supply PCB with their
guides and connectors in the housing and slowly but firmly push the instrument into
position.
CAUTION: Ensure that the instrument is correctly orientated. A stop
will operate if an attempt is made to insert the instrument in the
wrong orientation (e.g. upside-down). This stop must not be
over-ridden.

SELECTION OF INPUT TYPE AND OUTPUT 1 TYPE
The selection of input type and Output 1 type is accomplished on link jumpers on the
CPU PCB. The CPU PCB may be either of two forms: (a) for a relay, solid state or SSR
drive Output 1 (see Figure 7-4) or for a DC Output 1 (see Figure 7-5).
7.5.1
Input Type
The required input type is selected on
link jumpers LJ1/LJ2/LJ3 on the CPU PCB
(see Figure 7-4 or 7-5, as appropriate,
and Table 7-1).

The required type of Output 1 is
selected by Link Jumpers LJ4, LJ5, LJ6
and LJ7 on the Relay/SSR Drive/Solid
State Output 1 CPU PCB (see Figure 7-4
and Table 7-2) or, on the DC Output 1
CPU PCB, Link Jumpers LJ8 and LJ9 (see

OUTPUT 2 TYPE/OUTPUT 3 TYPE
The type of output for Output 2 and Output 3 is determined by the Option PCB fitted
in the appropriate position (see Figure 7-1) and, in the case of the DC Output Option
PCB being fitted, the setting of Link Jumpers LJ8 and LJ9 on that Option PCB (see
Figure 7-6 and Table 7-3). There are four types of option PCB which may be used for
Output 2 and Output 3:
1. Relay Output Option PCB (no link jumpers)
2. SSR Drive Output Option PCB (no link jumpers)
3. Solid State Output Option PCB (no link jumpers) - Output 2 only
4. Analog DC Output Option PCB (link jumpers as shown in Figure 7-6)
