OPERATING INSTRUCTIONS
In normal operation, the operator must not remove the Controller from its housing
or have unrestricted access to the rear terminals, as this would provide potential
contact with hazardous live parts.
Installation and configuration must be undertaken by technically-competent
servicing personnel. This is covered in Volume II of this manual.

OVERRIDE FEATURE
In either Dual Setpoint operation or Remote Setpoint operation, the Override
feature is available. This enables the active setpoint selected by the digital input
to be manually overridden from the keyboard. To engage the Override feature,
with the Controller displaying the desired setpoint value (see Subsection 1.1):
This indicates that the displayed setpoint is now the active setpoint, regardless of
the state of the digital input. To cancel an Override condition, press the same
keys again with this display shown.
1.3
VIEWING/ADJUSTING THE SETPOINT VALUE
If the desired setpoint display (i.e.
lower display showing the legend
SP, SP1, SP2 or LSP as appropriate)
is selected (see Subsection 1.1), the
setpoint value can be adjusted
using the Raise/Lower keys.
1.4
VIEWING/ADJUSTING THE SETPOINT RAMP RATE
If setpoint ramping is enabled, the
ramp rate display may be selected
(see Subsection 1.1). The ramp rate
(expressed in units/hour) may be
adjusted (using the Raise/Lower
keys) within the range 1 to 9999.
Any attempt to increase the value
beyond 9999 will cause the upper
display to go blank and setpoint
ramping to be switched OFF (default).

OM063-1
PM-0063
NOTES: The Pre-Tune facility will not engage if the setpoint is currently
ramping or if the process variable is less than 5% of input span from the
setpoint. Since the Pre-Tune facility is a single-shot operation, it will
automatically dis-engage itself once the operation is complete. The
Pre-Tune facility and the RaPID feature may be engaged together (see
Subsection 1.11).
1.10
SELF-TUNE FACILITY
This facility is used to optimise tuning whilst the Controller is operating. Self-Tune
may be activated as follows:

THE RaPID FEATURE
To engage the RaPID feature:
The same key action is used to dis-engage the RaPID feature.
To engage the RaPID feature and the Pre-Tune feature together:
The Pre-Tune feature then performs its single-shot operation (AT indicator will flash
green), after which the RaPID feature automatically starts to operate (AT indicator
will be ON green). For a detailed description of the RaPID feature, refer to
Appendix B.
NOTE: If either PB1 or PB2 is zero, the RaPID feature cannot be engaged.

SET UP MODE
2.1
ENTRY INTO SET UP MODE
NOTE: If the upper display shows:
one or more of the critical Configuration Mode parameters - typically input
range or output use/type - have been altered and, as a consequence, all
Set Up Mode parameters have been automatically set to their default
values/settings. To clear this display, alter any Set Up Mode parameter (see
below). It is recommended that Set Up Mode parameters are adjusted to
requirements only after all configuration parameters have been finalised.

2.2
SET UP MODE PARAMETERS
The parameters available for view/adjustment in
Set Up Mode are summarised in Table 2-1.
When Set Up Mode is entered, the lower display
will show the legend for the first parameter (Filter
Time Constant) and the filter time constant value
will be shown in the upper display. The user may
then select and adjust Set Up Mode parameters
(see left). In each case, the legend identifying
the parameter will be shown in the lower display
and the current value/setting will be shown in
the upper display.
2.2.1
Input Filter Time Constant
The Controller input is equipped with a digital filter which is used to filter out any
extraneous impulses on the process variable. This filtered PV is used for all
PV-dependent functions (control, alarms etc.).
CAUTION: If this parameter is set to an excessively high value, the control
quality may be significantly impaired. The value chosen should be
sufficiently large to attenuate stray noise on the process variable signal but
no larger.
2.2.2
Process Variable Offset
This parameter is used to modify the actual process variable value (measured at
the Controller’s input terminals) in the following manner:
Offset PV value = Actual PV value + Process Variable Offset value.
For Controllers fitted with a linear input, the displayed process variable value is
limited by Scale Range Maximum (see Subsection 2.2.35) and Scale Range
Minimum (see Subsection 2.2.36). The offset process variable value is used for all
PV-dependent functions (control, display, alarm, recorder output etc.).
CAUTION: This parameter value should be chosen with care. Any
adjustment to this parameter is, in effect, a calibration adjustment.
Injudicious application of values to this parameter could lead to the
displayed process variable value bearing no meaningful relationship to the
actual process variable value. There is no front panel indication when this
parameter is in effect (i.e. has been set to a non-zero value).

This parameter is the current Output 1 power level.

2.2.4
Output Power 2
This parameter is the current Output 2 power level (if Output 2 is fitted). It is a
“Read Only” parameter and is not adjustable.
2.2.5
Proportional Band 1
This parameter is the portion of the input span of the Controller over which the
Output 1 power level is proportional to the displayed process variable value. The
function of Proportional Band 1 is illustrated in Figure 2-1.
2.2.6
Proportional Band 2
This parameter is the portion of the input span of the Controller over which the
Output 2 power level is proportional to the displayed process variable value. In
Figure 3-2, Proportional Band 2 is shown (a) with a non-zero value (Case 1 and
Case 2) - PID control, and (b) with a zero value (Case 3) - ON/OFF control.
2.2.7
Reset (Integral Time Constant)
This parameter is adjustable in the range 1 second to 99 minutes 59 seconds and
OFF (value greater than 99 minutes 59 seconds). This parameter is not applicable
if Proportional Band 1 (see Subsection 2.2.5) is set to 0 (ON/OFF control).
2.2.8
Rate (Derivative Time Constant)
This parameter is adjustable in the range 00 seconds to 99 minutes 59 seconds.
This parameter is not applicable if Proportional Band 1 (see Subsection 2.2.5) is set
to 0 (ON/OFF control).
2.2.9
Overlap/Deadband
This defines the portion of the Proportional Band (Proportional Band 1 +
Proportional Band 2) over which both outputs are active (or, in the case of a
deadband, neither output is active). It is adjustable within the range –20% to
+20% (negative value = deadband). The function of the overlap/deadband is
illustrated in Figure 2-1.
Note that, with Output 2 set to ON/OFF control (Figure 2-1 Case 3), the
Overlap/Deadband parameter has the effect of moving the ON Differential band
of Output 2 to create an overlap (positive values) or a deadband (negative
values). When Overlap/Deadband = 0, the “Output 2 OFF” edge of the Output 2
ON/OFF Differential band coincides with the point at which Output 1 reaches 0%.

2.2.10 Bias (Manual Reset)
This bias to the output power is expressed as a percentage of output power. This
parameter is not applicable if Proportional Band 1 = 0.
2.2.11 ON/OFF Differential
This is a switching differential used when one or both outputs have been set to
ON/OFF control (i.e. Proportional Band 1 or Proportional Band 2 or both = 0).
2.2.12 Setpoint High Limit
This is the maximum limit for setpoint adjustment. It should be set to a value which
prevents the setpoint being given a value which will cause damage to the
process being controlled.
2.2.13 Setpoint Low Limit
This is the minimum limit for setpoint adjustment. It should be set to a value which
prevents the setpoint being given a value which will cause damage to the
process being controlled.
2.2.14 Remote Setpoint Maximum
This, and the Remote Setpoint Minimum parameter (see below) define the scaling
of the RSP input (which is a linear input). After scaling, the RSP value range is
limited by the Setpoint High Limit. Thus, if the scaled RSP value is greater than the
Setpoint High Limit, the RSP value will be clamped to the Setpoint High Limit.
2.2.15 Remote Setpoint Minimum
This, and the Remote Setpoint Maximum parameter (see above) define the
scaling of the RSP input (which is a linear input). After scaling, the RSP value range
is limited by the Setpoint High Limit and Setpoint Low Limit. Thus, if the scaled RSP
value is less than the Setpoint Low Limit, the RSP value will be clamped to the
Setpoint Low Limit.
2.2.16 Remote Setpoint Offset
This parameter is used to modify the remote setpoint value in the following
manner:
Offset remote setpoint value = setpoint value + remote setpoint
offset value.

Volume I
OM063-2
PM0063
2.2.17 Recorder Output Scale Maximum
This parameter defines the value of process variable or setpoint (whichever is
applicable) at which the Recorder Output reaches its maximum value; for
example, for a 0 - 5V Recorder Output, this value corresponds to 5V. The decimal
point position for the Recorder Output is always the same as that for the process
variable input range. This parameter is not applicable if the Recorder Output
option is not fitted.
2.2.18 Recorder Output Scale Minimum
This parameter defines the value of the process variable or setpoint (whichever is
applicable) at which the Recorder Output reaches its minimum value; for
example, for a 0 - 5V Recorder Output, this value corresponds to 0V. The decimal
point position for the Recorder Output is always the same as that for the process
variable input range. This parameter is not applicable if the Recorder Output
option is not fitted.
2.2.19 Output 1 Power Limit
This parameter is used to limit the power level of Output 1 and may be used to
protect the process being controlled. If no protection is required, this parameter
may be set to 100% (the default value). This parameter is not applicable if
Proportional Band 1 is set to 0.
2.2.20 Output 1 Cycle Time
The cycle time value required is dependent upon the process being controlled
and the type of output being used for Output 1. For a Relay Output, the cycle
time should be as large as possible (whilst remaining compatible with the process
control requirements) in order to maximise relay life. For an SSR Drive Output or
Solid State Output, the cycle time may have a lower value (and thus satisfy the
requirements of a fast-change process variable e.g. flow or pressure). This
parameter is not applicable if Proportional Band 1 is set to 0 or if Output 1 is a DC
linear output.
2.2.21 Output 2 Cycle Time
The cycle time value required is dependent upon the process being controlled
and the type of output being used for Output 2. For a Relay Output, the cycle
time should be as large as possible (whilst remaining compatible with the process
control requirements) in order to maximise relay life. For an SSR Drive Output or
Solid State Output, the cycle time may have a lower value (and thus satisfy the
requirements of a fast-change process variable e.g. flow or pressure). This
parameter is not applicable if Proportional Band 1 or Proportional Band 2 is set to
0 or if Output 2 is not fitted or is a DC linear output.

2.2.22 Process High Alarm 1 Value
This parameter, applicable only when Alarm 1 is selected to be a Process High
alarm, defines the process variable value at or above which Alarm 1 will be
active. The operation of a process high alarm is illustrated in Figure 2-2.
2.2.23 Process Low Alarm 1 Value
This parameter, applicable only when Alarm 1 is selected to be a Process Low
alarm, defines the process variable value at or below which Alarm 1 will be
active. The operation of a process low alarm is illustrated in Figure 2-2.
2.2.24 Band Alarm 1 Value
This parameter, applicable only if Alarm 1 is selected to be a Band Alarm, defines
a band of process variable values, centred on the setpoint value. If the process
variable value is outside this band, the alarm will be active. The operation of a
band alarm is illustrated in Figure 2-2.
2.2.25 Deviation (High/Low) Alarm 1 Value
This parameter, applicable only if Alarm 1 is selected to be a Deviation High/Low
Alarm, defines a value above (positive value - Deviation High alarm) or below
(negative value - Deviation Low alarm) the setpoint; if the process variable
deviates from the setpoint by a margin greater than that defined by this
parameter, Alarm 1 goes active. The operation of Deviation Alarms is illustrated in
Figure 2-2.
2.2.26 Alarm 1 Hysteresis
This parameter applies a hysteresis band on the “safe” side of the Alarm 1 value.
Thus, Alarm 1 will become active when the Alarm 1 value is exceeded; Alarm 1
will become inactive when the process variable value is outside the hysteresis
band on the “safe” side of the Alarm 1 value. The effect of the hysteresis value on
the operation of the different types of alarm is illustrated in Figure 2-3.
2.2.27 Process High Alarm 2 Value
This parameter, applicable only when Alarm 2 is selected to be a Process High
alarm, defines the process variable value at or above which Alarm 2 will be
active. The operation of a process high alarm is illustrated in Figure 2-2.

2.2.29 Band Alarm 2 Value
This parameter, applicable only if Alarm 2 is selected to be a Band Alarm, defines
a band of process variable values, centred on the setpoint value. If the process
variable value is outside this band, the alarm will be active. The operation of a
band alarm is illustrated in Figure 2-2.
2.2.30 Deviation (High/Low) Alarm 2 Value
This parameter, applicable only if Alarm 2 is selected to be a Deviation High/Low
Alarm, defines a value above (positive value - Deviation High alarm) or below
(negative value - Deviation Low alarm) the setpoint; if the process variable
deviates from the setpoint by a margin greater than that defined by this
parameter, Alarm 2 goes active. The operation of Deviation Alarms is illustrated in
Figure 2-2.
2.2.31 Alarm 2 Hysteresis
This parameter applies a hysteresis band on the “safe” side of the Alarm 2 value.
Thus, Alarm 2 will become active when the Alarm 2 value is exceeded; Alarm 2
will become inactive when the process variable value is outside the hysteresis
band on the “safe” side of the Alarm 2 value. The effect of the hysteresis value on
the operation of the different types of alarm is illustrated in Figure 2-3.
2.2.32 Loop Alarm Enable
This parameter is the means by which the user can enable or disable the Loop
Alarm. The Loop Alarm is a special alarm which detects faults in the control
feedback loop by continuously monitoring process variable response to the
control output(s).
The Loop Alarm facility, when enabled, repeatedly checks the control output(s) for
saturation i.e. either or both outputs being at the maximum or minimum limit. If an
output is found to be in saturation, the Loop Alarm facility starts a timer; thereafter,
if the saturated output has not caused the process variable to be corrected by a
pre-determined amount (V) after a time (Loop Alarm Time) has elapsed, the Loop
Alarm goes active. Subsequently, the Loop Alarm facility repeatedly checks the
process variable and the control output(s). When the process variable starts to
change value in the correct sense or when the saturated output comes out of
saturation, the Loop Alarm is de-activated.
OM063-2
Volume I

PM0063
For PID control, the Loop Alarm Time is always set to twice the value of the Reset
(Integral Time Constant) parameter. For On/Off control, the value of the Loop
Alarm Time parameter (see Subsection 2.2.33) is used. The value of V is
dependent upon the input type:
°C ranges:
2°C or 2.0°C
°F ranges:
3°F or 3.0°F
Linear ranges:
10 least significant display units
For single output Controllers, the saturation limits are 0% and Out1Max%. For dual
output Controllers, the saturation limits are –100% and Out1Max%.
NOTES:
1. Correct operation of the Loop Alarm depends upon reasonably
accurate PID tuning.
2. The Loop Alarm is automatically disabled during Manual Control Mode
and during execution of the Pre-Tune facility. Upon exit from Manual
Control Mode or after completion of the Pre-Tune routine, the Loop Alarm is
automatically re-enabled (if selected).
2.2.33 Loop Alarm Time
When full ON/OFF control is selected (i.e. Proportional Band 1 is set to 0) and Loop
Alarm is enabled, this parameter determines the duration of the saturation
condition after which the Loop Alarm will be activated. This parameter is omitted
from the Set Up display sequence if ON/OFF control is not selected or Loop Alarm
is disabled.
2.2.34 Scale Range Decimal Point
This parameter, applicable only if a linear
primary input is fitted, defines the position
of the decimal point in values of the
process variable, setpoint, alarm levels and
recorder outputs as shown on the right.

TUNING THE CONTROLLER MANUALLY
2.4.1
Controllers Fitted with Output 1 Only
Before starting to tune the Controller to the load, check that the Setpoint High and
Low Limits (SPhi and SPLo) are set to safe levels.
The following simple technique may be used to determine values for proportional
band (Pb1), derivative time constant (rAtE) and integral time constant (rSEt).
NOTE: This technique is suitable for use only with processes which are not
harmed by large fluctuations in the process variable. It provides an
acceptable basis from which to start fine tuning for a wide range of
processes.
1. Set the setpoint to the normal operating process value (set it to a lower
value if overshoot beyond the normal operating process value is likely to
cause damage).
2. Dis-engage the RaPID feature (see Subsection 1.11) if it is currently
engaged.
3. Select ON/OFF Control (i.e. set Pb1 = 0).
4. Switch on the process. Under these conditions, the process variable will
oscillate about the setpoint and the following parameter values should be
noted:
(a) The peak-to-peak variation (P) of the first cycle i.e. the difference
between the highest value of the first overshoot and the lowest value
of the first undershoot - see Figure 2-4)
(b) The cycle time (T) of this oscillation in minutes (see Figure 2-4)

NOTE: After setting up the parameters, set the Controller to Operator Mode
(see Subsection 2.5) to prevent unauthorised adjustment to the values.
2.4.2
Controllers Fitted with Output 1 and Output 2
Before starting to tune the Controller to the load, check that the Setpoint High and
Low Limits (SPhi and SPLo) are set to safe levels.
The following simple technique may be used to determine values for proportional
band (Pb1), derivative time constant (rAtE) and integral time constant (rSEt).
NOTE: This technique is suitable for use only with processes which are
not harmed by large fluctuations in the process variable. It provides
an acceptable basis from which to start fine tuning for a wide range
of processes.
1. Tune the Controller using Output 1 only as described in Subsection 2.4.1.
2. Set Pb2 to the same value as Pb1 and monitor the operation of the
Controller in dual output mode. If there is a tendency to oscillate as control
passes into the Output 2 proportional band, increase the value of Pb2. If
the process appears to be over-damped in the region of the Output 2
proportional band, decrease the value of Pb2.
3. When values of proportional bands, integral time constant and derivative
time constant have been determined for tuning, if there is a “kick” as
control passes from one output to the other, set OL to a positive value to
introduce some overlap. Adjust the value of OL by trial and error until
satisfied.
2.5
EXIT FROM SET UP MODE
To leave Set Up Mode, select the initial Operator Mode
display (normally process variable) then depress the
Raise and Function keys simultaneously, whereupon the
Controller will return to Operator Mode. NOTE: An
automatic return to Operator mode will be executed if
there is no key activity in Set Up Mode for two minutes.

RS485 SERIAL COMMUNICATIONS
The RS485-compatible serial communications option provides the means for
communication between the Controller and a master device (e.g. a computer or
terminal). This may be used on two-wire systems or three-wire systems.
3.1
COMMUNICATIONS ENABLE/DISABLE
When Communications are enabled (in Set Up Mode - see Subsection 2.2.36), the
Controller parameters may be adjusted by the master device via the serial
communications link. If communications are disabled, the Controller will not adjust
or change any parameters in response to commands received from the master
device and will send a negative acknowledgement in response to such
commands. Whether communications are enabled or disabled, the Controller will
return the requested information in response to a Type 2 Interrogation message
(see Subsection 3.2.5) from the master device.
3.2
PHYSICAL REQUIREMENTS
3.2.1
Character Transmission
Data format is fixed to be even parity, seven data bits and one stop bit. The Baud
rate may be selected to be 1200, 2400, 4800 (default) or 9600 Baud.
3.2.2
Line Turn-Round
The communications link is operated as a multi-drop half duplex system. When a
device is transmitting, it drives the transmission lines to the appropriate levels;
when it is not transmitting, its outputs are set to a high impedance in order that
another device can transmit. It is important that a transmitter releases the
transmission lines before another device starts transmission. This imposes the
following restraints on the master device:
(a) The transmitter must release the transmission lines within 6ms of
the end of the last character of a message being transmitted. Note
that delays due to buffers such as those used in universal
asynchronous receivers/trans-mitters (UARTs) within the master device
must be taken into account.
(b) The transmitter must not start transmission until 6ms has elapsed
since the reception of the last character of a message.
All Controllers in this range having an RS485 communications facility adhere to this
standard; thus, provided that the master device conforms similarly to the
standard, there should be no line contention problems.
3-1
Volume I
OM063-3
PM-0063
3.2.3
Communications Protocol
The protocol assumes half duplex communications. All communication is initiated
by the master device. The master sends a command or query to the addressed
slave and the slave replies with an acknowledgement of the command or the
reply to the query. All messages, in either direction, comprise:
(a) A Start of Message character
(b) One or two address characters (uniquely defining the slave)
(c) A parameter/data character string
(d) An End of Message character
Messages from the master device may be one of four types:
Type 1:
Type 2:
Type 3:
Type 4:
L {N} ? ? *
L {N} {P} {C} *
L {N} {P} # {DATA} *
L {N} {P} I *
Table 3-1
where all characters are in ASCII code and:
L
{N}
is the Start of Message
character (Hex 4C)
is the slave Controller
address (in the range 1 32); addresses 1 - 9 may be
represented by a single digit
(e.g. 7) or in two-digit form,
the first digit being zero (e.g. 07).

No space characters are permitted in messages. Any syntax errors in a received
message will cause the slave controller to issue no reply and await the Start of
Message character.

PM-0063
3.2.4
Type 1 Message
L {N} ? ? *
This message is used by the master device to determine whether the addressed
slave Controller is active. The reply from the slave Controller, if it is active, is
L {N} ? A *
An inactive Controller will give no reply.
3.2.5
Type 2 Message
L {N} {P} {C} *
This type of message is used by the master device to interrogate or modify a
parameter in the addressed Controller. {P} identifies the parameter and {C}
represents the command to be executed, which may be one of the following:
+ (Hex 2B) - Increment the value of the parameter defined by {P}
– (Hex 2D) - Decrement the value of the parameter defined by {P}
? (Hex 3F) - Determine the current value of the parameter defined by {P}
The reply from the addressed Controller is of the form:
L {N} {P} {DATA} A *
where {DATA} comprises five ASCII-coded digits whose format is shown in Table
3-1. The data is the value requested in a query message or the new value of the
parameter after modification. If the action requested by the message from the
master device would result in an invalid value for that parameter (either because
the requested new value would be outside the permitted range for that
parameter or because the parameter is not modifiable), the Controller replies with
a negative acknowledgement:
L {N} {P} {DATA} N *
The {DATA} string in the negative acknowledgement reply will be indeterminate. If
the process variable or the deviation is interrogated whilst the process variable is
outside the range of the Controller, the reply is L{N}{P}<??>0A* if the process
variable is over-range, or L{N}{P}<??>5A* if the process variable is
under-range.
Scan Tables
A parameter identifier character “]” in the message from the master device
indicates that a “Scan Table” operation is required. This provides a facility for
3-3
OM063-1
PM-0063
interrogating the values of a group of parameters and status in a single message
from the master device. The reply to such a command would be in the form:
L {N} ] xx aaaaa bbbbb ccccc ddddd eeeee A *
where xx is the number of data digits to follow; this is 20 for a single-control-output
instrument and 25 for a dual-control-output instrument. The digits are expressed as
shown in Table 3-1. For further information, refer to Subsection 3.5.6.3.
3.2.6
Type 3 Message
L {N} {P} # {DATA} *
This message type is used by the master device to set a parameter to the value
specified in {DATA}. The command is not implemented immediately by the slave
Controller; the slave will receive this command and will then wait for a Type 4
message (see below). Upon receipt of a Type 3 message, if the {DATA} content
and the specified parameter are valid, the slave Controller reply is of the form:
L {N} {P} {DATA} I *
(where I = Hex 49) indicating that the Controller is ready to implement the
command. If the parameter specified is invalid or is not modifiable or if the
desired value is outside the permitted range for that parameter, the Controller
replies with a negative acknowledgement in the form:
L {N} {P} {DATA} N *
3.2.7
Type 4 Message
L {N} {P} I *
This type of message is sent by the master device to the addressed slave
Controller following a successful Type 3 message transmission and reply to/from
the same slave Controller. Provided that the {DATA} content and the parameter
specified in the preceding Type 3 message are still valid, the slave Controller will
then set the parameter to the desired value and will reply in the form:
L {N} {P} {DATA} A *
where {DATA} is the new value of the parameter. If the new value or parameter
specified is invalid, the slave Controller will give a negative acknowledgement:
L {N} {P} {DATA} N *
where {DATA} is indeterminate. If the immediately-preceding message received
by the slave Controller was not a Type 3 message, the Type 4 message is ignored.

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.
1.2
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 1-1.
Figure 1-1
Panel Cutout Dimensions
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:
1
-DIN Controllers: (48n - 4) millimetres or (3.78n - 0.16) inches.
8

Main Dimensions
The procedure to panel-mount the Controller is shown in Figure 1-3.
CAUTION: Do not remove the panel gasket, as this may result in inadequate
clamping of the instrument in the panel.
NOTE: The mounting clamp tongues may engage in the ratchets either on
the sides of the Controller housing or on the top/bottom faces of the
Controller housing. Therefore, when installing several Controllers
side-by-side in one cutout, use the ratchets on the top/bottom faces.
Once the Controller is installed in its mounting panel, it may be subsequently
removed from its housing, if necessary, as described in Subsection 2.1.

1.3.1
Mains (Line) Input
The Controller will operate on 96 - 264V AC 50/60Hz mains (line) supply. The power
consumption is approximately 4 VA.
CAUTION: This equipment is designed for installation in an enclosure which
provides adequate protection against electric shock. Local regulations
regarding electrical installation should be rigidly observed. Consideration
should be given to prevention of access to the power terminations by
unauthorised personnel. Power should be connected via a two-pole
isolating switch (preferably situated near the equipment) and a 1A fuse, as
shown in Figure 1-4. 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.
1.3.2
24V (Nominal) AC/DC Supply
The supply connections for the 24V AC/DC version of the Controller are shown in
Figure 1-4. Power should be connected via a two-pole isolating switch and a
315mA slow-blow fuse (anti-surge Type T). The nominal 24V supply may be in the
following ranges:
24V (nominal) AC 50/60Hz 24V (nominal) DC -
1.3.3
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 3.3).
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.
1.3.4
RTD Inputs
The compensating lead should be connected to Terminal 3. For two-wire RTD
inputs, Terminals 2 and 3 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 length).
SM063-1
Volume II
1-5
PM-0063
1.3.5
Linear Inputs
For linear mA input ranges, connection is made to Terminals 1 and 4 in the
polarity shown in Figure 1-4. For linear mV and V ranges, connection is made to
Terminals 2 and 3 in the polarity shown in Figure 1-4. For details of the linear input
ranges available, refer to Appendix A.
1.3.6
Dual Setpoint Selection
With the Dual Setpoint option fitted, Terminals 16 and 17 are used for external
selection of the active setpoint. These terminals may be connected to (a) the
voltage-free contacts of a switch or relay, or (b) a TTL-compatible voltage.
Setpoint selection is as follows:
Voltage-Free:
Contacts open - Setpoint 1 selected
Contacts closed - Setpoint 2 selected
TTL-compatible:
>2.0V - Setpoint 1 selected
<0.8V - Setpoint 2 selected
NOTE: The Dual Setpoint option and the RS485 Serial Communications
option are mutually exclusive.
1.3.7
Remote Setpoint Selection Input
With the Remote Setpoint option fitted, Terminals 8 and 9 are used for external
selection of either the remote setpoint or the local setpoint. These terminals may
be connected to (a) the voltage-free contacts of a switch or relay, or (b) a
TTL-compatible voltage. Setpoint selection is as follows:
Voltage-Free:
Contacts open - Local setpoint selected
Contacts closed - Remote setpoint selected
TTL-compatible:
>2.0V - Local setpoint selected
<0.8V - Remote setpoint selected
With the Remote Setpoint option fitted and Dual Setpoint switching selected (see
Subsection 3.2.3), Terminals 8 and 9 are used for external selection of Setpoint 1
or Setpoint 2:
Voltage-Free:
Contacts open - Setpoint 1 selected
Contacts closed - Setpoint 2 selected
TTL-compatible:
>2.0V - Setpoint 1 selected
<0.8V - Setpoint 2 selected
This enables a Controller to be equipped with the RS485 Serial Communications
option and be capable of dual setpoint operation.

1.3.8
Remote Setpoint Input
With the Remote Setpoint option fitted, the secondary analogue input on
Terminals 5, 6 and 7 is used as the remote setpoint input. The following input types
are available:
0 - 20mA, 4 - 20mA,
0 - 5V, 1 - 5V, 0 - 10V, 2 - 10V,
0 - 50mV, 10 - 50mV, 0 - 100mV
Potentiometer (up to 2kΩ)
For further information, refer to Appendix A.
1.3.9
Relay Outputs
Refer to Figure 1-4. The contacts are rated at 2A resistive at 120/240V AC.
1.3.10 Solid State Outputs
These outputs provide up to 1A AC drive with a longer lifetime than an
electromechanical relay. For further details, refer to Appendix A.
1.3.11 SSR Drive Outputs
Refer to Figure 1-4. These outputs produce a time-proportioned non-isolated DC
signal (0 - 4.3V nominal, output impedance 250 ohms).
1.3.12 DC Outputs
See Figure 1-4 and Appendix A.
1.3.13 RS485 Serial Communications Link
The three-wire RS485 serial communications connections are on Terminals 16, 17
and 18, as shown in Figure 1-4. 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. The cables 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.
NOTE: The RS485 Serial Communications option and the Dual Setpoint
option are mutually exclusive.

REMOVING THE CONTROLLER FROM ITS HOUSING
CAUTION: Before removing the Controller from its housing, ensure that
all power has been removed from the rear terminals.
To withdraw the Controller from its housing, simply grip the side edges of the front
panel (there is a finger grip on each edge) and pull the Controller forwards. This
will release the Controller from its rear connectors in the housing and will give
access to the Controller PCBs. Take note of the orientation of the Controller for
subsequent replacement into the housing.The positions of the PCBs in the
Controller are shown in Figure 2-1.

NOTES:

If Output 2 is set to be a relay/SSR drive/solid state
output, it may be a control output (COOL) 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 set to be a relay/SSR drive/solid state
output, it can only be 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.
3.
It can be seen from the table above that the SSR Drive
output and the Solid State output share the same
Hardware Definition Code. However, these two output
types to not have the same sales ordering code.
SSR Drive Output = 2; Solid State Output = 8.
The maximum setting available for this code is 4777. For example, the code for a
Controller with 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 Controller’s hardware configuration (change of input/output
type, alarm/recorder output added/removed etc.). The Controller software
depends upon this code to ensure that the Controller operates correctly.
This code may be viewed as a Read Only display in Operator Mode (see Volume

Alarm Inhibit Feature
On power-up, an “alarm” condition may occur, based on the alarm value, the
process variable value and, if appropriate to the alarm type, the (active) setpoint
value. This would normally activate an alarm. However, if the pertinent alarm is
inhibited, the alarm indication is suppressed andf the alarm will remain inactive.
This will prevail until the “alarm” condition returns to the “inactive” state, whereafter
the alrm will operate in its normal fashion.
Also, during dual setpoint operation or remote/local setpoint operation, whenever
there is switching from one setpoint to the other, similar alarm suppression will
occur if the pertinent alarm is inhibited.

APPENDIX B
RaPID CONTROL FEATURE
RaPID (Response-assisted PID) offers dramatic improvements in control quality
compared with conventional PID techniques. It responds more effectively than PID
techniques to load conditions. With this feature, the Controller’s response at
start-up, during setpoint changes and during disturbances shows considerably
reduced overshoot and much shorter settling times (see Figure B-1).
Figure B-1
SM063-B
Comparison of RaPID Control with Standard PID Control
Volume II
B-1
PM-0063
RaPID works best with well-tuned PID terms. It is therefore recommended, on
newly-installed Controllers, that the Pre-Tune facility (see Volume 1 Subsection 1.9)
is run before RaPID is engaged.
NOTE: If Pre-Tune and RaPID are both engaged, Pre-Tune will run first. Once
Pre-Tune (a single-shot process) is automatically dis-engaged, RaPID will
operate automatically.
In conditions of frequent change in load characteristics, it is recommended that
the Self-Tune facility (see Volume 1 Subsection 1.10) is used.
NOTE: With Self-Tune and RaPID engaged together, Self-Tune is suspended
until RaPID is dis-engaged, whereupon Self-Tune will operate
automatically.

APPENDIX C
ALARM HYSTERESIS OUTPUT
The Alarm Hysteresis option for Output 2 Usage and Output 3 Usage in
Configuration Mode provides compatibility with the identical feature in some
earlier controllers in this range.
An Alarm Hysteresis output is made active only when both alarms become active;
it subsequently becomes inactive only when both alarms are inactive. Therefore,
the status of an Alarm Hysteresis output when only one alarm is active depends
upon the alarm status immediately prior to that alarm being activated; thus:
