Wiring
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).

To Remove the Controller
from its Sleeve
Ease the latching ears c outwards and pull
the controller forward.
When plugging back in ensure that the
latching ears click into place to maintain

Ensure that you have the
correct supply for your
controller
1. Check order code of the controller
supplied
2. Use copper conductors only.
3. The power supply input is not fuse
protected. This should be provided
externally.
Safety requirements for permanently
connected equipment state:
• A switch or circuit breaker shall be
included in the building installation
• It shall be in close proximity to the
equipment and within easy reach of the
operator
• It shall be marked as the disconnecting
device for the equipment.
Note: a single switch or circuit breaker can
drive more than one instrument.

Operator Level 2
Parameters are available in deeper levels of access protected by security codes.
Level 2 parameters are typically used when commissioning the controller.
To Select Level 2
1. From any display press and hold until LEv1 is shown
2. Release and press V or W to choose Lev 2 (Level 2)
3. Press V or W to enter the pass code. Default = ‘2

General Notes about Relays and
Inductive Loads
When switching inductive loads such as
contactors or solenoid valves, wire the
22nF/100Ω ‘snubber’ supplied across the
normally open relay terminals. This will
prolong contact life and reduce interference.
! WARNING
Snubbers pass 0.6mA at 110V and 1.2mA
at 230Vac, which may be sufficient to
hold on high impedance loads. Do not
use in these installations.

Safety and EMC Information
This instrument is intended for industrial temperature and process control applications within the requirements of the European Directives on
Safety and EMC.
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.
! The safety and EMC protection can be seriously impaired if the unit is not used in the manner specified. The installer must
ensure the safety and EMC of the installation.
Safety. This instrument complies with the European Low Voltage Directive 73/23/EEC, by the application of the safety standard EN 61010.
Unpacking and storage. If on receipt, the packaging or unit is damaged, do not install but contact your supplier. If being stored before use,
protect from humidity and dust in an ambient temperature range of -30oC to +75oC.
Electrostatic discharge precautions. Always observe all electrostatic precautions before handling the unit.
Service and repair. This instrument has no user serviceable parts. Contact your supplier for repair.
Cleaning. Isopropyl alcohol may be used to clean labels. Do not use water or water based products. A mild soap solution may be used to clean
other exterior surfaces.
Electromagnetic compatibility. This instrument conforms with the essential protection requirements of the EMC Directive 89/336/EEC, by the
application of a Technical Construction File. It satisfies the general requirements of the industrial environment defined in EN 61326.
Caution: Charged capacitors. Before removing an instrument from its sleeve, disconnect the supply and wait at least two minutes to allow
capacitors to discharge. Avoid touching the exposed electronics of an instrument when withdrawing it from the sleeve.
Safety Symbols. Symbols used on the instrument have the following meaning:
! Caution, refer to accompanying documents) Equipment protected throughout by DOUBLE INSULATION
Installation Category and Pollution Degree. This unit has been designed to conform to BSEN61010 installation category II and pollution
degree 2, 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. However, a temporary conductivity caused by condensation must be
expected.
Personnel. Installation must only be carried out by suitably qualified personnel
Enclosure of Live Parts. To prevent hands or metal tools touching parts that may be electrically live, the controller must be installed 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 for use in 240Vac CATII.
Wiring. It is important to connect the unit in accordance with the data in this sheet ensuring that the protective earth connection is ALWAYS
fitted first and disconnected last. Wiring must comply with all local wiring regulations, i.e. UK, the latest IEE wiring regulations, (BS7671), and USA,
NEC Class 1 wiring methods.
! Do not connect AC supply to low voltage sensor input or low level inputs and outputs.
Voltage rating. The maximum continuous voltage applied between any of the following terminals must not exceed 240Vac:
• 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 240Vac with respect to ground and the product would not be safe.
Conductive pollution. Electrically conductive pollution i.e. carbon dust, MUST be excluded from the enclosure in which the controller is
installed. To secure a suitable atmosphere in conditions of conductive pollution, fit an air filter to the air intake of the enclosure. Where
condensation is likely, include a thermostatically controlled heater in the enclosure.
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. To prevent overheating of the process under fault conditions, a separate over-temperature protection unit
should be fitted which will isolate the heating circuit. This must have an independent temperature sensor.
Note: Alarm relays within the unit will not give protection under all failure conditions.
Installation Requirements for EMC. To comply with European EMC directive certain installation precautions are necessary:-
• General guidance. Refer to EMC Installation Guide, Part no. HA025464.
• Relay outputs. It may be necessary to fit a suitable filter to suppress conducted emissions. Filter requirements depend on the type of load.
Typical applications may use Schaffner FN321 or FN612.
• Table top installation. If using a standard power socket, compliance with commercial and light industrial emissions standard is usually required.
To comply with conducted emissions standard, a suitable mains filter must be installed, such as Schaffner FN321 or FN612.
Switch On
If the controller has not
previously been configured it will
start up, showing the ‘Quick
Configuration’ codes.

*****
The quick code consists of 5
characters in the format:-
12345
This allows input and output
functionality to be configured as
in shown in the table below.
! Incorrect
configuration can result in
damage to the process and/or
personal injury and must be
carried out by a competent
person authorised to do so. It
is the responsibility of the
person commissioning the
controller to ensure the
configuration is correct.
If the controller has been
previously configured using the
Quick Codes, it will start up

always be done by powering
down the controller, holding
down the button, and
powering up the controller again.
You must then enter a passcode
using the W or V buttons. In
a new controller the passcode
defaults to 4. If an incorrect
passcode is entered you must
repeat the whole procedure.
