Press and hold ✱and use the ▲ or ▼ buttons to select from the choices Rly , SSd or
AnLG depending on the model supplied. SP2 and SP3 outputs will be automatically
allocated. (See output options table on page 8).
4To enter initial configuration into controller memory
Press and hold both ▲ and ▼ buttons for 3 seconds. The display will now read
PArK
and measured variable (e.g. ambient temperature 23°). PArK is displayed because a
setpoint has not yet been entered.
To display setpoint units
Press and hold ✱The displays will now read
unit (eg. °C ) and 0
To enter setpoint
Press and hold ✱and use ▲ button to increase or ▼ button to decrease the reading and
scroll to required setpoint value. (The digit roll-over rate increases with time).
THE CONTROLLER IS NOW OPERATIONAL
WITH THE FOLLOWING FACTORY SETTINGS
Proportional band/Gain 10ºC/18ºF/100 units
Integral time/Reset 5 mins
Derivative time/Rate 25 secs
Proportional cycle-time 20 secs
(Typical setting for relay output)
DAC Derivative approach control 1.5
(Average setting for minimum overshoot)
Note: For more precise control or for non temperature applications where a Linear input
transducer is being used, the controller may need to be tuned to the process.
Please refer to the following section on AUTOTUNE.
AUTOTUNE
This is a single shot procedure to match the controller to the process. Select either Tune or
Tune at Setpoint from the criteria given below.
The Tune program should be used for applications other than those listed under Tune at
Setpoint below. The procedure will apply disturbances when the temperature or process
reaches 75% of the setpoint value, causing overshoot which is monitored in order to adjust
the DAC overshoot inhibit feature. Care should be taken to ensure that any overshoot is safe
for the process.
The Tune at Setpoint program is recommended when:
●The process is already at setpoint and control is poor
●The setpoint is less than 100°C in a temperature application
●Re-tuning after a large setpoint change
●Tuning multi-zone and/or heat-cool applications.
Notes: DAC is not re-adjusted by Tune at setpoint. Proportional Cycle Time can be pre-
selected before running the Autotune program. (see page 5).
GETTING STARTED
After power-up the controller requires programming with the following information:
Type of Sensor (See list of sensors p.22)
Operating unit °C °F bAr PSi Ph rh SEt
Allocation of Output Device to SP1/SP2 (Relay / SSd) or analog. SP3 is always relay.
Setpoint
When the above information has been programmed into the controller it will be
operational with factory PID settings.
INITIAL SET-UP
On power-up the controller will display the self test sequence followed by the initial
display
inPt : nonE
1Select input sensor.
Press and hold ✱and use the ▲or ▼buttons to scroll through the sensor selection
list until the correct sensor is displayed. Release the buttons. The display will now read
selected sensor type e.g.
inPt : tCS (type S thermocouple).
Press ▲once The display will now read
unit : nonE
LINEAR INPUT
When Linear Input is selected, the display resolution of the setpoint and many other
functions will be changed from the setting previously made at
di.SP in Level 2, to that set
at
dECP in Level A.
It is therefore recommended that on completion of the Initial Set-up the Linear Input
settings in Level A be completed before moving on to configure Levels 1, 2 and 3. (see
Set-up Procedure page 6).
2Select operating unit.
Press and hold ✱and use the ▲or ▼ buttons to scroll through the unit selection list
until the correct unit is displayed. Release the buttons. The display will read selected
unit e.g.
unit : °C
Press ▲once The display will now read SP1.d : nonE
3Select SP1 (Main setpoint output device)
Analog output
The allocation of the analog output to SP1 automatically overrides the default
proportional cycle time setting of 20 seconds. Where the analog output is allocated
to SP2, the default
CyC.2 setting on/off must be manually changed in Level 1 to a
time proportioning setting to enable the analog output to operate in proportional
control mode.

AUTOTUNE (continued)
TUNE OR TUNE AT SETPOINT PROGRAM
Enter program (▲▼) and from the display tunE : oFF press and hold ✱ and press ▲ to
display
tunE : on or tunE : At.SP Exit program mode (▲▼).
The TUNE program will now start. The display will show tunE as the process variable
climbs to setpoint.
Note: Avoid tuning while running a program as SP1 may be different from the target
setpoint..
When the TUNE or TUNE AT SETPOINT program is complete the PID values are entered
automatically. The process will rise to setpoint and control should be stable. If not, this may
be because optimum cycle time is not automatically implemented. To set the cycle time
see PROPORTIONAL CYCLE-TIME.
PROPORTIONAL CYCLE-TIME
The choice of cycle-time is influenced by the external switching device or load. eg.
contactor, SSR, valve. A setting that is too long for the process will cause oscillation and a
setting that is too short will cause unnecessary wear to an electro-mechanical switching
device.
Factory set
To use the 20 sec factory set cycle-time no action is needed whether autotune is used or
not.
To Manually Select AUTOTUNE Calculated CYCLE-TIME
When AUTOTUNE is completed, enter program (▲▼) and select
CYC.t in Level 1. The
display will read
CYC.t : 20 (the factory setting).
To view the new calculated optimum value, press and hold both ✱ and ▼ buttons until
indexing stops. The calculated value will be displayed eg.
A16 . If acceptable, exit program
(▲▼) to implement this setting.
To Pre-select Automatic Acceptance of AUTOTUNE Calculated CYCLE-TIME
Before AUTOTUNE is initiated select
CYC.t in Level1, press and hold both ✱and ▼buttons
until indexing stops at
A – – . Exit program (▲▼) to accept calculated value automatically.
To Manually Pre-select Preferred CYCLE-TIME
Before AUTOTUNE is initiated select
CYC.t in Level 1, press and hold both ✱and ▲ or ▼
buttons until indexing stops at preferred value then exit program (▲▼) to accept.

LINEAR INPUT
Set-up Procedure
The 4–20mA input model converts current into voltage using an internal resistor which
spreads the signal across the input range 10 to 50 mV. using multiplier of 2.5. When using a
transducer with an output less than 4–20mA, the input maximum and minimum mV values
can be calculated using the same multiplier.
Models with 0to 5V input use an internal resistor to spread the signal across the input
range 0 to 50 mV using a divider of 100. Where a transducer provides a smaller output, the
input maximum and minimum values can be similarly calculated.
Decide what scale minimum and maximum will be required, and whether the scale needs
inverting. (See Level A; Linear Input Scaling for list of settings and limits, page 10).
The example below shows how a 4–20mA linear Input should be configured.
# e.g. 4–20mA = 60 to 260 units where 4mA = 60 units
Follow INITIAL SET-UP procedure (also see page 4).

FUNCTION OVERVIEW
The Programmer function in Level P enables the Model 9500P to control applications
needing Setpoint changes over time. Examples of this are Ramp changes where a gradual
Rate of change can be set, or Step changes which are instantaneous. These can be
separated by Soak periods during which the process is held at a constant value. Each
individual time interval of the program or Segment, together with it’s associated moving
setpoint value can be stored as a unique Program and for example be represented by the
diagram below.
Setpoint
Ramp
Soak Step
Time (Segments)
In addition to those settings that determine the segment profile, it is also necessary to set
program start values, together with the preferred ramp rate time units for each individual
program.
At the end of a sequence, a Program can be arranged to repeat (Loop), either a specified
number of Cycles, or continuously. Only one Loop can be included in a Program. When
the program is running, the Display indicates progress through the sequence of segments,
and can additionally be interrogated for further segment information.
To speed up Program configuration, several Edit functions have been provided so that
individual Segments and Programs may be Deleted or Inserted, and an entire Program
may be Copied and then Pasted into another that it will replace.
For safety reasons, three modes of recovery from a power failure are available. These either
automatically Re-start the Program from the beginning, Continue it from where it stopped,
or Hold it waiting for a user re-start.
Either one or both of the two auxiliary outputs can be configured as Event outputs.
Engaging the Holdback feature will temporarily halt Setpoint ramping to allow the process
temperature to catch up should it deviate by more than a pre-set amount during a Ramp
segment.
To afford maximum programming flexibility, memory is allocated dynamically, and not pre-
allocated. This allows the user the freedom to configure a small number of long programs
or a larger number of shorter ones, up to the permitted maximum of 126 Segments per
program, and a limit of 31 Programs. Should these limits be exceeded, or the Programmer
memory become fully used, the display will read ProG FULL. Programs can be planned
using the Memory Allocation Table which details the memory requirements of individual
segment types. During configuration a check can be kept on memory usage by
interrogating the USEd feature of the display to give an instant reading of ‘percentage
memory used’.
Finally, once a program has been configured, it can be run from the run off/on/hold
controls in Level P, and in addition a quick access run/hold toggle is directly available from
the front panel.
The Programmer Functions List describes the full range of available Settings for each
Programmer Function together with their display mnemonic. The Model 9500P is supplied
with a suite of Factory Settings for each Function. These are shown in bold type.
The Functions Map illustrates the relationship between the Functions and their Settings
and provides a guide to the Keying Operations required to navigate around the menu
when configuring or running a Program.

GETTING STARTED (PROGRAMMER)
For users with previous experience of configuring programmers, the Function List and
Functions Map on pages 14/15 and 16/17 respectively will be reasonably self explanatory.
The Functions and their Settings are grouped to maximise speed of Programming.
New users should take a short time to study the following before starting to configure the
first program, and may wish to take on board the following tips and suggestions.
Program Mode Exit switch ( ProG/Auto ) Program Level 4.
This standard feature of the Model T2016P2 causes automatic exit from program mode after
sixty seconds of Key inactivity. It is highly recommended that this setting be disabled and
changed to
ProG/StAy to ensure that adequate time is available for making unfamiliar
adjustments. (see page 9). It may also be useful at this point to consider the setting also on
Level 4,
SEt.L that enable the Programmer menu entry point to be changed from it’s default
position to the point of last exit. (see page 9).
Program Parameter List
Listing the required Program Settings and Parameter Values segment by segment beside
each Setting/Segment Number, and Program Display Mnemonic will reduce the risk of
programming mistakes during the learning period.
Memorise Basic Key Functions
Use the Function Map on pages 14 and 15 to become familiar with the following Menu
Navigation principles.
Hold both ▲ and ▼ for three seconds to enter or exit Program Mode.
Key either ▲ or ▼ to view Functions (follow horizontal arrows).
Key either ✱▲ or ✱▼ to view or change settings (follow vertical arrows).
Key ✱ and hold for three seconds to confirm Edit Functions.
Note: Factory Settings appear in the lower display in each of the Functions illustrated in
the Function Map.
Program configuration
When the PROGRAMMER function is entered at LEVL P, the Programmer is automatically
presented in Configuration Mode, and the instrument display can be used to access and
adjust the various FUNCTIONS as they appear in the FUNCTIONS MAP illustrated on pages 14
and 15.
Program Run Mode
To run a Program from LEVL P,
Press ▲ once, then use ✱▲ to select the required program number from the
PrOG list.
Press ▲ again once then use ✱▲ to select the run/on option.
Press ▼▲ and hold for three seconds to exit configuration mode and run the program.
Run/Hold Toggle Feature
Press ✱▼ and hold for 3 seconds to hold the program.
Press ✱▼ again and hold for 3 seconds to run the program.
Note: Level P is ‘read only’ while a program is active.
DISPLAY FUNCTIONS
Once the program is running, the display automatically tracks the progress of the program as
it indexes through it’s sequence of segments. When it concludes it’s final instruction, the
upper display alternates
StoP with the Process Value and the lower display reverts to the
instrument SP1 Setpoint.
RAMP
The upper display alternates between SPr and the moving Process Value while the lower
display shows Target Setpoint. If Holdback is activated, the decimal point in the lower right
corner of the upper display will be illuminated.
SOAK
The upper display alternates between SoAK and the Process Value. The lower display
reads the Target Setpoint of the current segment.
STEP (not displayed)
As this involves an instantaneous change of the Target Setpoint, this segment occupies zero
time and the program immediately moves to the next segment. The lower display then
registers the new Target Setpoint, with the upper display alternating in either
SPr or SoAK
mode according to the segment configuration.
HOLD
If the program is paused in HOLD, the upper display alternates between hoLd and the
Process Value, while the lower display indicates the Target Setpoint of the current
segment.
User Displays
With the program running, a further display function is available at any time.
Press and hold ✱ Display shows Program Number
Also press ▲ once Display shows Segment Number
Press ▲ again Display shows number of loops completed if a loop function has
been set.
Press ▲ again Upper display reads
t.SP
Lower display shows moving Ramp setpoint
Or if in Soak Segment Upper display reads
Sint (Soak interval)
Lower display reads remaining Soak time

MECHANICAL INSTALLATION
The Controller is designed to be sleeve mounted in a 1/16 DIN panel cutout with only the
front panel rated to NEMA4/IP66, provided that:
● the panel is smooth and the panel cutout is accurate;
● the mounting instructions are carefully followed.
DIN PANEL CUTOUT
1/16 DIN: 45.0mm +0.6 / -0.0 wide, 45.0mm +0.6 / -0.0 high
Maximum panel thickness 9.5mm
Minimum spacing 20mm vertical, 10mm horizontal
MOUNTING
To mount a Controller proceed as follows:
1 Check that the controller is correctly orientated and then slide the unit into the cutout.
2 Slide the panel clamp over the controller sleeve pressing it firmly against the panel until
the controller is held firmly.
3 The controller front bezel and circuit board assembly can be unplugged from the sleeve.
Grasp the bezel firmly by the recesses on each side and pull. A screwdriver can be used
as a lever if required.
4 When refitting the bezel assembly it is important to press it firmly into the sleeve until the
latch clicks in order to compress the gasket and seal to NEMA4X/IP66.
CLEANING
Wipe down with damp cloth (water only)
CAUTION: The controller should be isolated before removing or refitting it
in it’s sleeve. Live circuits can hold a charge for short periods after isolation
from voltage supply. Electrostatic precautions should be observed when
handling the controller outside it’s sleeve.

OUTPUT DEVICES
WARNING:
Three types of output device may be factory fitted to the controllers, and users must choose
how to allocate these to outputs SP1 and SP2. (SP3 is always RLY). Check the model number
and output configuration against the Output Options Table on page 8 before wiring the
instrument and applying power.
1 Solid state relay drive (SSd1/SSd2)
6Vdc (nominal) 20mA max.
To switch remote SSR (or logic)
2 Miniature power relay (rLY/rLY1/rLY3)

3 Analog Output (
AnLG ) (isolated)
Specify; 4–20mA 500Ωmax +/- 0.1% fs typical
0–5Vdc 10mA (500Ωmin) +/- 0.1% fs typical
0–10Vdc 10mA (1KΩmin) +/- 0.1% fs typical
SUPPLY VOLTAGE
100–240V 50–60HZ 6.0VA (nominal)
+/- 10% maximum permitted fluctuation
WIRING THE CONNECTOR
Prepare the cable carefully, remove a maximum of 8mm insulation and ideally tin to avoid
bridging. Prevent excessive cable strain. Maximum recommended wire size: 32/0.2mm 1.0mm2
(18AWG).
INDUCTIVE LOADS
To prolong relay contact life and suppress interference it is recommended engineering practice
to fit a snubber (0.1uf/100 ohms) between relay output terminals.
CAUTION:
Snubber leakage current can cause some electro-mechanical devices to be held ON.
Check with the manufacturers specifications.

EN61010 - /CSA 22.2 No 1010.1 92
Compliance shall not be impaired when fitted to the final installation.
Designed to offer a minimum of Basic Insulation only.
The body responsible for the installation is to ensure that supplementary insulation suitable for
Installation Category II or III is achieved when fully installed.
To avoid possible hazards, accessible conductive parts of the final installation should be
protectively earthed in accordance with EN61010 for Class 1 Equipment.
Output wiring should be within a Protectively Earthed cabinet.
Sensor sheaths should be bonded to protective earth or not be accessible.
Live parts should not be accessible without the use of a tool.
When fitted to the final installation, an IEC/CSA APPROVED disconnecting device should be used
to disconnect both LINE and NEUTRAL conductors simultaneously.
A clear instruction shall be provided not to position the equipment so that it is difficult to
operate the disconnecting device.
* EMC Immunity
EMC immunity may be improved by fitting large Ferrite cores around the sensor cables at the
point where they enter the cabinet and an earth bond is recommended.
TYPICAL APPLICATION
In this example the load temperature is monitored by a temperature transducer/transmitter
which provides a 4–20mA input signal to the controller. The 4–20mA output has been
