LEDs Installation Safety Requirements ROUTING OF WIRES Protective earth terminal 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 To minimise interference from electrical noise, low voltage DC connections and sensor input wiring must be routed away from high-current power cables. If this is not practical, use shielded cables, shield grounded at both ends, and keep cable lengths to a minimum. General This unit is intended for Industrial Temperature and Process Control applications, within the requirements of the European Directives on Safety and EMC. The Safety and EMC protection provided can be seriously impaired, if the instrument is not used in the manner specified. The installer MUST ensure the Safety and EMC of all installations. Installation MUST only be carried out by qualified personnel. UNPACKING AND STORAGE ENCLOSURE OF LIVE PARTS The packaging contains the unit, this sheet, and a CD. If on receipt, the packaging or unit are damaged, do NOT install, but contact the supplier. If being stored before use, protect from humitity and dust in an ambient temperature range of -30ºC to +75ºC. To prevent hands or metal tools touching parts that may be electrically live, the unit must be installed in an enclosure. Caution: Electrostatic discharge 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 all local wiring regulations, i.e. UK, the latest IEE wiring regulations (BS7671), and USA, NEC Class 1 wiring methods. Only use copper conductors for connections. Terminal tightening torque 0.4Nm max. Caution Do not connect AC supply to low voltage sensor input or other low level inputs and outputs. Always observe all electrostatic precautions, before handling the unit. SERVICE AND REPAIR Use Isolpropyl Alcohol to clean label. Labels will become illegible if water or water based products are used. A mild soap solution can be used to clean other exterior surfaces. Manufacturer’s name: Eurotherm Limited Manufacturer’s address: Faraday Close, Worthing, West Sussex BN13 3PL, United Kingdom CONDUCTIVE POLLUTION Product type: Process controller and programmer Electrically conductive pollution, i.e. carbon dust, MUST be excluded from the enclosure in which the unit 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. Model(s): Mini8 Safety specification: EN61010-1 EMC emissions specification: EN61326 Class A EMC immunity specification: EN61326 Industrial locations It is recommended that the power supply to the system is fused appropriately to protect the cabling to the unit. 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 to 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 Mini8 Controller is a compact DIN Rail mounting 16 loop PID controller and data acquisition unit. It offers a choice of I/O and field communications. I/O Connection Terminals Power Supply Declaration of Conformity OVERCURRENT PROTECTION Note. Alarm relays within the unit will not indicate all failure conditions. What is the Mini8 Controller? CLEANING The installation must include a power isolating switch or circuit breaker. This should be in close proximity (1 meter) to the unit, in easy reach of the operator and marked as the disconnecting device for the unit. When designing a contol 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 damage the process machinery being controlled, or even cause a fire. If the heating remains constantly on the temperature sensor is detached from the process thermocouple wiring thas short circuited unit fails with the heating output constantly on external valve or contactor is sticking in the heating condition unit setpoint is set to high Where damage or injury can occur, it is recommended that a separate over-temperature protection unit, and independant temperature sensor, to isolate the heating circuit, is fitted.

The Mini8 Controller is mounted on a 35mm Top Hat DIN Rail. It is pre-assembled in the factory, configured with sufficient I/O required for the application as specified in the order code. With standard applications the Mini8 Controller is also supplied as a configured instrument. Alternatively it can be configured using the iTools configuration suite running on a personal computer. Part No. HA028497 Issue 4 Mar 06 The Mini8 Controller Communications Interface Communications - Modbus TO MOUNT THE UNIT Various operational functions are indicated through the LED’s across the top of the unit. All controllers have a configuration port and a field communication port on the communications module. Protocol is Modbus RTU, RS422, RS485 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. The connectors includes 2 LEDs, a Yellow LED showing communication activity and a Green LED showing transmitted data. This unit is intended to be mounted horizontally on a symmetrical DIN rail, 35 x 7.5 or 35 x 15, to the requirements of EN50022. Note. It must be mounted in an enclosure and is for interior use only. See Note LEDS Note. If the Run mode (RN) red LED is permanently ON, the unit is operating normally. RJ45 Pin Colour Configuration Port A The RS232 configuration port is just below the LEDs on an RJ11 socket. The Mini8 Controller is configured via the iTools configuration software running on a PC communicating via the network. Note. The unit will NOT be controlling, while being configured.

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.
