Mini8™ CONTROLLER
INSTALLATION AND WIRING INSTRUCTIONS
HA028497/7 (CN27932)
Installation Category And Pollution Degree
This unit has been designed to conform to BS EN61010 installation category II
and pollution degree 2. These are defined as follows:
 Installation category II. The rated impulse voltage for equipment on
nominal 230V ac mains is 2500V.
Pollution degree 2. Normally, only non-conductive pollution occurs.
However, occasionally a temporary conductivity caused by condensation
shall be expected.
Personnel
Installation MUST be carried out only by qualified personnel.
Enclosure Of Live Parts
To prevent hands or metal tools touching parts that may be electrically live,
the unit must be installed in an enclosure.
Wiring
It is important to connect the unit in accordance with the data on this
sheet, ensuring the protective Earth connection is ALWAYS fitted first and
disconnected last. Wiring MUST comply with local wiring regulations, e.g. in
the UK, the latest IEE wiring regulations (BS7671), or for the USA, NEC Class
1 wiring methods. Use only copper conductors for connections. Terminal
tightening torque 0.4Nm max.
Caution
Do not connect AC supply to low voltage sensor input or low level inputs and outputs.
Power Isolation
The installation must include a power isolating switch or circuit breaker.
This should be in close proximity to the unit (< 1 metre), in easy reach of the
operator and marked as the disconnecting device for the unit.
Overcurrent Protection
It is recommended that the power supply to the system be fused appropriately
to protect the cabling to the unit.
Conductive Pollution
Electrically conductive pollution, e.g. carbon dust, MUST be excluded from
the enclosure in which the unit is installed. To secure a suitable atmosphere in
conditions of conductive pollution, an air filter should be fitted to the air intake
of the enclosure. Where condensation is likely, a thermostatically controlled
heater should be included in the enclosure.
Over-temperature Protection
When designing a control system it is essential to consider the consequences
should any part of the system fail. In temperature control applications the
primary danger is the heating will remain constantly on. This could spoil the
product, but more seriously, it might damage the process machinery being
controlled, or even cause a fire.
Reasons for the heating remaining on continuously include:
1The temperature sensor is detached from the process
2The thermocouple wiring has short circuited
3The unit has failed with the heating output constantly on
4The external valve or contactor is sticking in the heating condition
5Unit setpoint is set too high
Where damage or injury can occur, it is recommended that a separate
over-temperature protection unit, and an independent temperature sensor, to
isolate the heating circuit, be fitted.
Note Alarm relays within the unit do not indicate all failure conditions.
Installation Requirements For EMC
To comply with European EMC directive certain installation precautions are
necessary:
For general guidance, refer to EMC Installation Guide, part no. HA025464.
With relay outputs, it may be necessary to fit suitable filters to suppress
conducted emissions. Filter requirements depend on the type of load. Typical
applications may use Schaffner FN321 or FN612.
For table-top installation, if a standard power socket is to be used, 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.

THE ADDRESS SWITCH
This switch is situated at the bottom of the Comms slot. Switches 1 to
7 are used to configure the instrument unit ident parameter. Switch 8
is used for DHCP (Dynamic Address) enabling.
Note Use iTools to configure the address when the switches are set 0 and the
unit identifier parameter is set to ‘Instr’.
ALLOCATION OF IP ADDRESS
DHCP is where the instrument (IP host) will ask a DHCP server to
provide it with an IP Address. Typically this happens at start-up, but can
be repeated during operation. DHCP includes the concept of assigned
values that will ‘expire’.
A DHCP server is required that can respond to the request. The DHCP
server will need to be configured to correctly respond to the request.
This configuration depends on the local company network policy.

COMMUNICATIONS - MODBUS
Protocol is Modbus RTU, EIA422, EIA485 3-wire or 5-wire.
The Modbus network connection is two RJ45 sockets connected
in parallel. This allows category 5 patch cables to be used, the first
socket into the unit and the second one out to daisy-chain on to the
next slave, or for a line terminator.
RJ45 COMMUNICATION TERMINATORS
The communication line must daisy-chained from unit to unit with
the unit at each end of the chain correctly terminated. A black
Modbus terminator containing the correct termination resistors is
available from the supplier, order code SubMin8/TERM/MODBUS/
RJ45.
Note The Baud rate is default to 19200, but can be set during configuration
using the iTools configuration software.
THE ADDRESS SWITCH
This switch is situated below the the Comms connector.
Each unit must have a unique address on the Modbus network.
Note If address 0 is set the unit will take the address and Parity settings from
the configuration of the instrument.
Note The Prog position must be selected when the instrument is started to
enable firmware upgrades.
