2.2 Wire Sizes
The screw terminals accept wire sizes from 0.5 to 1.5 mm (16
to 22AWG). Hinged covers prevent hands or metal making
accidental contact with live wires. The rear terminal screws
should be tightened to 0.4Nm (3.5lb in).
2.3 Precautions
• Do not run input wires together with power cables
• When shielded cable is used, it should be grounded at
one point only
• Any external components (such as zener barriers, etc)
connected between sensor and input terminals may
cause errors in measurement due to excessive and/or
un-balanced line resistance or possible leakage currents
• Not isolated from the logic outputs & digital inputs
• Pay attention to line resistance; a high line resistance
may cause measurement errors

• It is not necessary to fit an
external burden resistor to the
4-20mA input
• If the 4-20mA remote setpoint input is connected and
valid (>3.5mA; < 22mA) it will be used as the main
setpoint. If it is not valid or not connected the controller
will try to use the Volts input. Volts sensor break occurs at
<-1; >+11V. The two inputs are not isolated from each
other
• If neither remote input is valid the controller will fall back
to the internal setpoint, SP1 or SP2 and flash the alarm
beacon. The alarm can also be configured to activate a
relay or read over digital communications.
• To calibrate the remote setpoint, if required, see section
15.3.5
• A local SP trim value is available in access level 3.

2.10 General Note About Relays and
Inductive Loads
High voltage transients may occur when switching inductive
loads such as some contactors or solenoid valves. Through
the internal contacts, these transients may introduce
disturbances which could affect the performance of the
instrument.
For this type of load it is recommended that a ‘snubber’ is
connected across the normally open contact of the relay
switching the load. The snubber recommended consists of a
series connected resistor/capacitor (typically 15nF/100Ω). A
snubber will also prolong the life of the relay contacts.
A snubber should also be connected across the output
terminal of a triac output to prevent false triggering under
line transient conditions.
WARNING
When the relay contact is open or it is connected to a high
impedance load, the snubber passes a current (typically
0.6mA at 110Vac and 1.2mA at 240Vac). You must ensure
that this current will not hold on low power electrical
loads. If the load is of this type the snubber should not be
connected.

3. Safety and EMC Information
This controller is intended for industrial temperature and
process control applications when it will meet the
requirements of the European Directives on Safety and
EMC. Use in other applications, or failure to observe the
installation instructions of this handbook may impair safety
or EMC. The installer must ensure the safety and EMC of
any particular installation.
Safety
This controller complies with the European Low Voltage
Directive 73/23/EEC, by the application of the safety
standard EN 61010.
Electromagnetic compatibility
This controller conforms with the essential protection
requirements of the EMC Directive 89/336/EEC, by the
application of a Technical Construction File. This instrument
satisfies the general requirements of the industrial
environment defined in EN 61326. For more information on
product compliance refer to the Technical Construction File.
GENERAL
The information contained in this manual is subject to
change without notice. While every effort has been made to
ensure the accuracy of the information, your supplier shall
not be held liable for errors contained herein.
Unpacking and storage
The packaging should contain an instrument mounted in its
sleeve, two mounting brackets for panel installation and an
Installation & Operating guide.
If on receipt, the packaging or the instrument are damaged,
do not install the product but contact Super Systems, Inc. If
the instrument is to be stored before use, protect from
humidity and dust in an ambient temperature range of -30oC
o
to +75
C.
SERVICE AND REPAIR
This controller has no user serviceable parts. Contact Super
Systems, Inc. for repair.
Caution: Charged capacitors
Before removing an instrument from its sleeve, disconnect
the supply and wait at least two minutes to allow capacitors
to discharge. It may be convenient to partially withdraw the
instrument from the sleeve, then pause before completing
the removal. In any case, avoid touching the exposed
electronics of an instrument when withdrawing it from the
sleeve.
Failure to observe these precautions may cause damage to
components of the instrument or some discomfort to the
user.
Electrostatic discharge precautions
When the controller is removed from its sleeve, some of the
exposed electronic components are vulnerable to damage by
electrostatic discharge from someone handling the
controller. To avoid this, before handling the unplugged
controller discharge yourself to ground.
Cleaning
Do not use water or water based products to clean labels or
they will become illegible. Isopropyl alcohol may be used to
clean labels. A mild soap solution may be used to clean
other exterior surfaces of the product.
3.1 Installation Safety Requirements
Safety Symbols
Various symbols may be used on the controller. They have
the following meaning:
Caution, (refer to

accompanying documents )
Equipm ent protect ed
throughout by DOU BLE
INSULATION
Helpful hints
Personnel
Installation must only be carried out by suitably qualified
personnel in accordance with the instructions in this
handbook.
Enclosure of Live Parts
To prevent hands or metal tools touching parts that may be
electrically live, the controller must be enclosed in an
enclosure.
Caution: Live sensors
The controller is designed to operate if the temperature
sensor is connected directly to an electrical heating element.
However you must ensure that service personnel do not
touch connections to these inputs while they are live. With a
live sensor, all cables, connectors and switches for
connecting the sensor must be mains rated.
Wiring
It is important to connect the controller in accordance with
the wiring data given in this guide. Take particular care not
to connect AC supplies to the low voltage sensor input or
other low level inputs and outputs. Only use copper
conductors for connections (except thermocouple inputs)
and ensure that the wiring of installations comply with all
local wiring regulations. For example in the UK use the
latest version of the IEE wiring regulations, (BS7671). In the
USA use NEC Class 1 wiring methods.
Power Isolation
The installation must include a power isolating switch or
circuit breaker. This device should be in close proximity to
the controller, within easy reach of the operator and marked
as the disconnecting device for the instrument.
Overcurrent protection
The power supply to the system should be fused
appropriately to protect the cabling to the units.

Series 3 Operations Manual
Voltage rating
The maximum continuous voltage applied between any of
the following terminals must not exceed 264Vac:
• relay output to logic, dc or sensor connections;
• any connection to ground.
The controller must not be wired to a three phase supply
with an unearthed star connection. Under fault conditions
such a supply could rise above 264Vac with respect to
ground and the product would not be safe.
Conductive pollution
Electrically conductive pollution must be excluded from the
cabinet in which the controller is mounted. For example,
carbon dust is a form of electrically conductive pollution. To
secure a suitable atmosphere in conditions of conductive
pollution, fit an air filter to the air intake of the cabinet.
Where condensation is likely, for example at low
temperatures, include a thermostatically controlled heater in
the cabinet.
This produ ct has been designed to conform to BS EN61010
installat ion category II, pol lution degree 2 . These are defined as
follows:
Installation Category II (CAT II)
The rated impulse voltage for equipment on nominal 230V supply
is 2500V.
Pollution Degree 2
Normally only non conductive pollution occurs. Occasionally,
independent temperature sensor, which will isolate the
heating circuit.
Please note that the alarm relays within the controller will
not give protection under all failure conditions.
Routing of wires
To minimise the pick-up of electrical noise, the low voltage
DC connections and the sensor input wiring should be routed
away from high-current power cables. Where it is
impractical to do this, use shielded cables with the shield
grounded at both ends. In general keep cable lengths to a
minimum.
however, a temporary conductivity caused by condensation shall
be expected.
Grounding of the temperature sensor shield
In some installations it is common practice to replace the
temperature sensor while the controller is still powered up.
Under these conditions, as additional protection against
electric shock, we recommend that the shield of the
temperature sensor is grounded. Do not rely on grounding
through the framework of the machine.
Over-temperature protection
When designing any control system it is essential to consider
what will happen if any part of the system should fail. In
temperature control applications the primary danger is that
the heating will remain constantly on. Apart from spoiling
the product, this could damage any process machinery being
controlled, or even cause a fire.
Reasons why the heating might remain constantly on
include:
• the temperature sensor becoming detached from the
process
• thermocouple wiring becoming short circuit;
• the controller failing with its heating output constantly
on
• an external valve or contactor sticking in the heating
condition
• the controller setpoint set too high.
Where damage or injury is possible, we recommend fitting a
separate over-temperature protection unit, with an

4.4.4 Auto, Manual and Off Mode
!
The controller can be put into Auto, Manual or Off mode –
see next section.
Auto mode is the normal operation where the output is
adjusted automatically by the controller in response to
changes in the measured temperature.
In Auto mode all the alarms and the special functions (auto
tuning, soft start) are operative
Manual mode means that the controller output power is
manually set by the operator. The input sensor is still
connected and reading the temperature but the control
loop is ‘open’.
In manual mode the MAN beacon will be lit, Band and
deviation alarm are masked
The power output can be continuously increased or
decreased using the
Manual mode must be used with care. The power
level must not be set and left at a value that can damage
the process or cause over-heating. The use of a separate
‘over-temperature’ controller is recommended.
Off mode means that the heating and cooling outputs are
turned off. The process alarm and analogue retransmission
outputs will, however, still be active while Band and
deviation alarm will be OFF.

relay, set the value to 5.0 seconds or greater to prevent damage to the device due
to rapid switching.

6. Access to Further Parameters
Parameters are available under different levels of security
and are defined as Level 1 (Lev1), Level 2 (Lev2), Level 3
(Lev 3) and Configuration (Conf).
Level 1 has no passcode since it contains a minimal set of
parameters generally sufficient to run the process on a daily
basis.
Level 2 allows access to parameters which may used in
commissioning a controller or settings between different
products or batches.
Level 1 and Level 2 operation has been described in the
previous sections.
Level 3 and Configuration level parameters are also
available as follows:
6.1.1 Level 3
Level 3 makes all operating parameters available and
alterable (if not read only). It is typically used when
commissioning a controller.
Examples of parameters available in Level 3 are:
Range limits, setting alarm levels, communications
address.
The instrument will continue to control when in Levels 1, 2
or 3.
6.1.2 Configuration Level
This level makes available all parameters including the
operation parameters so that there is no need to switch
between configuration and operation levels during
commissioning. It is designed for those who may wish to
change the fundamental characteristics of the instrument
to match the process.
Examples of parameters available in Configuration level
are:
Input (thermocouple type); Alarm type; Communications
type.
WARNING
Configuration level gives access to a wide range of
parameters which match the controller to the process.
Incorrect configuration could result in damage to the
process being controlled and/or personal injury. It is the
responsibility of the person commissioning the process
to ensure that the configuration is correct.
In configuration level the controller is not controlling the
process or providing alarm indication. Do not select
configuration level on a live process.

6.2 Parameter lists
Parameters are organised in lists. The top of the list shows
the list header only. The name of the list header describes
the generic function of the parameters within the list. For
example, the list header ‘ALARM’ contains parameters
which enable you to set up alarm conditions.
6.2.1 To Choose Parameter List Headers
Press
this key is pressed.
The name of the list header appears in the lower display,
followed, after a few seconds, by a scrolling longer
description of the name.
The following example shows how to select the first two list
headers.
6.2.2 To Locate a Parameter
Choose the appropriate list, then press . Each parameter
in the list is selected in turn each time this button is
pressed. The following example shows how to select the
first two parameters in the ALARM List. All parameters in
all lists follow the same procedure.

6.2.3 How Parameters are Displayed
As shown above. whenever a parameter is selected it is
displayed as a mnemonic, of four or five characters, for
example ‘A1.TYP’.
After a few seconds this display is replaced by a scrolling
banner which gives a more detailed description of the
parameter. In this example ‘A1.TYP’ = ‘alarm 1 type’. The
scrolling banner is only shown once after the parameter is
first accessed.
The name of the list header is also displayed in this way.
The upper part of the display shows the value of the
parameter.
The lower part shows its mnemonic followed by the
scrolling name of the parameter
6.2.4 To Change a Parameter Value
With the parameter selected, press
