Euroterm 2604 Manuals

VL SUPPLY VOLTAGE OPTION This is suitable for connection to a power supply of 24Vac -15,+10% 48-62Hz or 24Vdc -15,+20%, 20W maximum. Note. This MUST be fused using a T type fuse (EN60127 time-lag type) rated at 4A. ! Caution Ensure that mains supplies are connected to the power supply terminals (100 to 230Vac only), the fixed relay terminals or to relay or triac modules. Under no circumstances should mains supplies be connected to any other terminals. A protective Earth connection is required. ALWAYS ensure that the protective Earth is fitted first and disconnected last. 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, a temporary conductivity caused by condensation must be expected. PERSONNEL Installation MUST only be carried out 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 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 (3.5lbin) 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 (1 meter) to the unit, 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 is fused appropriately to protect the cabling to the unit. CONDUCTIVE POLLUTION 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. OVER-TEMPERATURE PROTECTION 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. This may occur if the, � temperature sensor is detached from the process � thermocouple wiring has 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. Note. Alarm relays within the unit will not indicate 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. � 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. Installation Safety Requirements Various symbols used on the instrument are described below: !

POWER SUPPLY SPECIFICATION VH SUPPLY VOLTAGE OPTION This is suitable for connection to a power supply of between 100 and 230Vac ±15%, 48 to 62 Hz, 20W maximum. Note. This MUST be fused using a T type fuse (EN60127 time-lag type) rated at 1A. Digital I/O Terminals The eight digital I/O connections provided can be individually configured as, � Input. Inputs are Logic (-1 to 35Vdc) or Contact Closure, and can be configured for Manual, Remote, Run, Hold, Reset, etc, � Output. Outputs are open collector requiring an external power supply, and can be configured as event Alarms, Time proportioning or valve position outputs. Note. These terminals are NOT isolated from the Instrument ground.

See Note 2 I/O Expander Terminals DATA TRANSFER The primary use of the I/O Expander terminals (E1 and E2) is to connect an I/O Expander Module (Model No 2000IO). This adds a further 20 digital inputs and 20 digital outputs to this instrument. Data transfer is performed serially via a two wire interface from instrument to expander. DIGITAL INPUT These terminals can only be used as a secondary digital input if the I/O Expander is not fitted. If used in this way simply connect a 2K2, ¼W limiting resistor in series with the input.
