EWCM 800 series controller for compressor pack units

S Description

Technical Data

EWCM 800 controllers can be used to manage all compressors in a compressor room of refrigerating plant by means of the inlet pressure. These controllers offer reversal tables for the most used freon gases and enable therefore values to be displayed and set in bar, PSI, °C and °F. Depending models, they can have 4 (EWCM 840/S), 6 (EWCM 860/S) or 9 (EWCM 890/S) compressors; each compressor must have an alarm input to disconnect the system in the event of failure. It is possible to configure two different set points: for standard operation or for operation with limited requirements. The reduced set point can be configured by means of the internal clock or by a clock enabled with a digital input. EWCM 800 models have a RS485 serial connection for TelevisSystem. The values measured by the probes are displayed with 4 digits. These controllers are available with 230, 115, 24 or 12 Va power supplies.

Solutions for Refrigeration blast and quick chillers, ovens and monoblock split units

Description

Solutions for temperature blast chilling cells Cards for temperature blast chilling cells are electronic controllers which manage all blast chilling, freezing and preservation functions. These devices are suitable for all refrigeration and catering applications, but can be used also on combined devices, because they blast chill the product at temperatures close to 0°C or values suitable for deep–freezing, depending on requirements. These cards are therefore the ideal solution to guarantee a safe and optimal preservation of all types of food.

EWFC 1000 EWFC 1000 controllers are designed for temperature blast chilling and preserving cells. These controllers have three analogue inputs for PTC temperature probes, to control the defrost end and to measure the product temperature. They also have 3 digital inputs for the s of pressure switch alarms, and fan and door switch alarms. The switching from the positive, hard positive or negative blast chilling cycle to preservation cycle can occur when the temperature measured by the insertion probe (wire probe) has been reached or at a specified time, if this probe is not available. The cell thermostat is always on the cell probe. The control is configured to start at specific intervals of time, even if a "wire" probe is present and it has not been placed at the center of the product. Defrost cycles can be configured by the depending on requirements. An internal buzzer signals when the cycles have been correctly completed. The buzzer can also signal a pressure switch or cell probe alarm. The outputs on relays control all blast chiller actuators: compressor, fans, defrosting cycle and lights.

Description TelevisSystem150 is an efficient solution to monitor temperatures and any other physical units of measurements of refrigerating systems used for the preservation and processing of food. TelevisSystem150 program is able to communicate with a series of modules, designed to measure analogue values (temperature, humidity, etc.), logical statues (alarms, door switches, pressure switches) and with a series of instruments which can be connected to one other using an ordinary serial line linked to a Personal Computer. TelevisSystem150 can be installed in new or existing systems, regardless the type of controllers used for the regulation. The friendly and easy to use interface makes this system suitable also for beginners.

ALARM MANAGEMENT The devices linked on line continuously transmit the measured data to the computer, thus enabling s to promptly manage alarms and abnormal operating conditions. After detecting the fault, s can enable warning or emergency devices using the EWTV 280 module. A practical procedure enables to automatically transmit faxes/SMS messages every time an alarm occurs. Messages are automatically sent to the preset numbers of Help Centers or authorized operators.

ENABLING REMOTE ACTIONS REMOTO

Televis 150 can be connected, via modem and an ordinary telephone line, to a computer installed in a remote location as compared to the refrigerating system. The efficient software routines of the program enable s to carry out the actions remotely, thus facilitating the outsourcing of the management and troubleshooting of the refrigerating system. LOCALE

111

RECORDING AND PRINTING All the data transmitted from the modules to the PC are recorded at specific intervals, in accordance with the requirements or recommendations regarding food preservation. The data storage capacity of the PC is defined at the time the system is configured. All the values stored on the hard disk can be printed or displayed at any time. It is also possible to select a start or end date for the desired intervals of time. s can print reports, graphs and tables or customize the system according to the type of data analysis they wish to carry out.

DATA DISPLAY IN REAL TIME The main information transmitted by devices (inputs values and statuses) can be viewed in real time. The PC displays an immediate detailed overview of the system's status along with a series of functions that the can select for data analyses purposes. It is also possible to display the information stored in the system. A pane shows the list of all the devices that have detected an alarm condition. To display the details of an alarm or device, it is sufficient to select it. The second pane that opens displays real time and historical data.

112

TelevisSystem200 monitoring and remote management software

S Description TelevisSystem200 has been designed to monitor and manage problems associated to refrigerating systems. Operations can be carried out locally using a PC or from a Help Center via modem. The system enables s to simply and practically monitor and display all alarms.

LAYOUT The layout shows the physical arrangement of the instruments within the plant in which they are installed. Therefore, it enables to acquire immediate information on all the instruments from one location only. The main information is graphically displayed for each instrument shown. The program can manage up to 100 different layout sheets.

RVD The concept of virtual instrument has been specifically developed to help s to work on-site. The controller that needs to be managed is displayed, thus allowing s to select all the configuration and options on the screen as it were a real instrument. Most of new instruments can be connected using an optoinsulated RS485 line with high immunity from disturbances. The system can also automatically detect all the instruments connected to the PC. If the plant configuration is changed, it is sufficient to run this routine to reconfigure the system.

113

GLOBAL COMMANDS This function enables to simultaneously perform specific operations on all the devices with a single command. It is possible, for example, to switch the devices and lights on and off, or perform this operation for each single device. The diagnostic tool enables s the view the results of the commands they have selected for each device..

ALARM MANAGEMENT Televis 200 continuously queries the connected instruments, acquiring all possible data including information on the alarms reported. -friendly panes display information on the alarms in real time, thus enabling the to be continuously updated on the status of the system. If an alarm or abnormal situation occurs, TelevisSystem200 performs the action specified by the during set-up. For example, it can automatically send a detailed fax/SMS message to the preset numbers.

REMOTO

LOCALE

RECORDING AND PRINTING TelevisSystem200 continuously monitors the status of the system. s can therefore require information on the temperature of a specific unit or cell or even historical data. It is also possible to display information on previous failures and use this information to program scheduled maintenance before the occurrence of a serious problem. Printouts are compliant with the food standards. Data is printed with a resolution of one tenth to ensure full compliance of all printed documentation with applicable standards and regulations.

REMOTE MANAGEMENT

The most important advantage offered by Televis 200 lies in the possibility of completely controlling a system from a PC installed in a remote location as compared to the site of installation of the instruments. The use of a modem, the possibility of notifying alarms telephonically and the RVD function enable the operators of Help Centers to perform the same operations that are available on the local PC in the site of installation. Remote management functions enable s to send fax messages to preset numbers even if a computer is not available.

114

TelevisStation central unit with pre-installed Televis software

Description TelevisStation is ideally suited for Televis 150 and Televis 200 software because it is a personal computer that meets the more restrictive reliability and quality industry standards. The license for the application software must be purchased separately. The software is pre-installed and can therefore be immediately used after a few simple operations. The available models are TelevisStation3500 and TelevisStation3700 . This program is available in several versions, depending on the type and the language of the operating system installed and pre-installed software versions and models.

TelevisStation3500 TelevisStation3500 is compact and can be easily mounted on walls and on s (2 screws are required for wall-mounting, 1 for the safety lock). It is also possible to purchase an accessory (available on request) to protect the connectors and power switch from tampering. The LCD monitor display high resolution images, thus simplifying the use of the software. TelevisStation3500 also has a VGA for the connection of external monitors. The internal modem, approved in the main European countries, is pre-installed. To use the software (also remotely, via modem) immediately, it is sufficient to the telephone line. It is also possible to use an external modem without removing the internal one. The product contains the EWTK module (depending on the selected license) that usually interfaces the PC and the RS485 network. Therefore, only three network cable terminals (+, – and gnd) are used for the connection of TelevisStation3500 and for immediate programming. TelevisStation3500 also has a PS2 connector for the keyboard and another one for the mouse (accessories supplied). A parallel port for the printer and other auxiliary ports (RS232, USB, Ethernet) are also available for additional requirements and future expansions. A 3” 1/2 floppy drive (supplied) is also available. Although the software is compatible with several operating systems, it is preferable to use it with Microsoft Windows, as this OS enables to efficiently use the features of TelevisStation3500 and Station 150/200. The operating system (in Italian or in English) is supplied as standard. The availability of other languages must be checked when the order is placed.

TelevisCompact electronic unit for remote management and installation monitoring

S Description TelevisCompact is an electronic unit that enables to remotely manage plants and monitor installations by connecting several Televis compatible instruments to a network. Together with the two complementary software applications, TelevisInteractive and TelevisInteractivePlus, is the ideal solution for customers who wish to control a single installation (monitoring and plant management) and for customers who need to simplify the monitoring of several plants or require an automatic and centralized solution for remote installations. The installation and configuration of TelevisCompact is quick and easy. All operations can be performed from the keyboard of the devices, but also by means of the -friendly program for PCs (“Configuration tool”) that runs in a Windows environment. The products of the TelevisCompact family can record data at -defined time intervals.

TelevisCompact20 It is suitable for local monitoring applications. This program reads and saves data from devices connected on line (from a maximum of 35 devices at recording intervals of 15 minutes), detect alarm conditions and record them. If an alarm occurs, the device notifies its occurrence by switching the LED on the display on, enabling the buzzer and alarm relay, and by sending faxes and SMS to several s. All recorded data can be displayed on the LCD display and printed. If TelevisInteractive is used, it is also possible to transfer all the data saved to a TelevisCompact20 memory bank.

The data storage time interval varies according to the number of devices connected and to the time interval chosen for the recording. Collected data can be printed manually or automatically or transmitted, via modem, to a Help Center where the working software TelevisInteractive stores all the data. If an alarm occurs, the electronic exchange displays the information using a LED on the front . If a modem or fax is available, it is possible to send notifications via SMS to a Help Center or to TelevisInteractivePlus. The software stores the data and, if necessary, sends messages and alarm notifications for each alarm received from local installations. The system can also transmit (via fax) a daily status report, at the -defined time, and display a history of the last alarms occurred, both for system alarms (TelevisCompact) and network alarms (instruments connected to the system). A system prevents non authorized s from using the instrument. Three models of TelevisCompact are available: TelevisCompact20, TelevisCompact40 and TelevisCompact60. Not all the functions listed above are available for the three models. The sections that follow detail the characteristic of each model to allow s to select the version that best suits their needs.

117

TelevisCompact60 This application is particularly suitable to access data via modem. TelevisInteractive displays and changes the operating parameters of TelevisCompact60 as well as the instrument parameters of the tools linked on line. TelevisCompact60 can be configured to send alarms to TelevisInteractivePlus software, which records them and enables s to display and print them. Depending on the settings selected during the product configuration, it is also possible to filter the alarms and send them via fax or SMS even to multiple s. Thus, the software receives all data automatically and centrally and manages several installations. The information acquired on instrumentation can be periodically sent to TelevisInteractive or TelevisInteractivePlus to allow it to be centrally recorded; this function can be activated automatically to avoid that older data be erased when the memory is freed up to make space for new data. All other functions are identical to those of the previous model.

TelevisCompact40 If remote management of the installation only (or rather that there is no need locally to intervene directly) is of interest, this is the ideal product. It offers all the functions of TelevisCompact60 except that it has neither a display, nor a buzzer nor alarm relay. Furthermore the memory available is limited; this happens, obviously, since all the data are periodically sent to the TelevisInteractive central software or to TelevisInteractivePlus software which records them periodically and makes them available for future use.

Technical Data Casing: metallic varnished, IP20. Size: 197x198x60 (L x H x P). Mounting: on wall. Relay: free-voltage s, 12/24 Va/c, Imin 100mA - Imax 1A Power supply: 230 Va ±10%, 50/60 Hz. Absorption: max 5 VA. Connections: Televis RS485 port; 2 modem/PC RS232 ports; Centronics printer port.

CONFIGURATION TOOL This software automatically recognises all the devices connected to one TelevisCompact and enables the selection of desired operation by means of setting up the machine parameters. It is, thus, possible to quickly, simply and safely set up the tools’ names, the time interval for data acquisition, help centers, etc. Furthermore, it is possible to execute a series of advanced operations which must be carried out exclusively by specialized personnel; operations which allow to update the second language available for software and communication drivers with the tools; should the TelevisCompact model include it, the operations described may also be done via modem.

118

TelevisInteractive Family software for the remote and centralized management of one or more installations

Description

TelevisInteractive This software can be used to interact with TelevisCompact and the devices connected to it. It is also possible to directly connect the PC to TelevisCompact using the serial port or remotely via modem. This connection enables s to data or monitor all the devices connected on line. Connection via modem is available for TelevisCompact40 and TelevisCompact60 only. Collected data can be processed and exported, displayed and printed as table or chart. It is also possible to use the RVD (Remote Virtual Device) function and global commands on any device connected to the network. If appropriately configured, TelevisInteractive can also operate in “call waiting” mode. In this mode, data ing is carried out automatically without the operator's supervision. This function is also available onTelevisCompact40 and TelevisCompact60.

TelevisInteractivePlus The TelevisInterctivePlus software extends of TelevisInteractive. If set in "call mode" the software is able to receive alarm messages from one or more TelevisCompact40 or TelevisCompact60. The messages are stored for each single installation and are available for subsequent viewing. The incoming messages can be forwarded to the final recipients (including several s) at specific intervals of time (hour/day/month/year) that can be configured for each . Information on the activities undertaken and transmission result are saved and may be displayed at a later time along with all the other information associated with the alarm.

Televis network Example of connection of a TelevisSystem

Description Devices are connected to the network by means of a RS485 opto-insulated connection to ensure a higher protection from electromagnetic disturbances and electric noise. Some devices manufactured by Eliwell already have a RS485 serial connection, while others have a TTL serial output. The latter require a specific interface module to converts the TTL output into RS485 for the connection to the network. This module is part of the BusAdapter range. The devices that can be connected include Televis controllers described in several sections of this catalogue and data acquisition modules described in the last part of this section.

EWTV 280 alarm management module

S Description

Technical Data

The EWTV 280 module is a remote repeater for the management of signals of TelevisSystems. These signals may be generated by “system” alarms (excessively high or low temperature, power failure, faulty probe, etc.) which occur on instruments or other modules in the network. Signals are “sent” to EWTV 280 through the TelevisSystem software which, for this purpose, can relate the relay output to an instrument or a group of instruments. EWTV 280 provides a second relay which is triggered in the event of “no link” alarm (no communication on serial line from an instrument or module). In the event of communication failure due to cable breakdown or PC fault, an additional security feature in EWTV 280 activates both relays for alarm repetition. TelevisSystems can be connected to a maximum of 15 EWTV 280 modules. EWTV 280 is available in 70x85 mm standard size (4 DIN modules) for DIN rails (Omega 3) or for wall mounting and is directly powered by the mains.

O16, O52 Thermostats for cooling and ambient air

Description

Technical Data

016 and O52 are thermostats for room and commercial refrigeration, equipped with a unipolar SPDT switch that opens or closes when the temperature increases or decreases. The tripping temperature can be adjusted by means of a screw on all versions, while the differential is adjustable on some models only. Thermostats can also be equipped with a sensor to measure the air temperature, with straight capillary, with spiral capillary and remote bulb. Models with capillary, which enable temperature to be measured along the whole length, are used in applications in which the sensing element has a lower temperature as compared to the thermostatic head; the straight capillary is more suitable for longer distances, while the spiral one is recommended for smaller distances. Models with remote bulb, in which temperatures are detected by the sensing bulb only, are available with wide or narrow differential. It is also possible to order models with an integrated disconnect switch if it is necessary to stop the plant without changing the settings of the thermostat. The range also includes a model for ice refrigerators O16–H6999 with fixed calibration, specifically designed to cyclically adjust the thickness of ice by means of a water-filled bulb sensor. The special version for anti-frost O16–H8923 has a 6 m straight capillary that can be used to protect pipes, coils, etc. from frost. This is factory preset to start at 2°C and to disconnect at 3.5°C. For this model and for O16–H6951, a model with manual reset button is also available. O16 and O52 models differ only by the class of protection that is equivalent to IP66 for OH52 and to IP44 for O16.

Electrical ratings: the electrical rating of the unipolar SPDT switch is 16(16)A 250Va N.O. or N.C.; 1(1)A 250Va on the opposite side.

Wiring Diagram

151

Compliance: all models are compliant with EN60730–2–6 and EN60730–2–9, and manufactured in accordance with the requirements of standard ISO9001. These thermostats are also compliant with current European standards. Terminals: 1 common, 2 opens the when the temperature increases, 4 closes the when the temperature increases. Cable input: 14 mm insulating bushing for O16 and P.G. 16 connector for O52. Coolants: suitable to be used with all types of gases. Mounting: two male holes on the rear of the controller for the insertion of M4x6 mm screws (supplied with the thermostat). Differential: the differential is the difference between the enabling and disabling point of a variable. Given the characteristics of the “filling material” of temperature versions the differential may vary within the range of the thermostat. Control: by means of hex nut with cutout for cross screwdriver, present both on the shaft of the capacity and on that of the differential. There is also a control knob, which is supplied as standard with some O52 temperature controllers.

T24 Defrost timer with temperature sensor

171

Description

Technical Data

T24 are defrost timers in which the defrost cycle is enabled at a specific time (factory preset) or as soon as the defrost end temperature is reached. This condition is detected by a probe. These timers are also available in versions that delay the start of the fans at the end of the defrost cycle. Series T24–100 The start of the defrost cycle closes 2–3 that enables the electric heater and opens 3–4 that switches the compressor off. The defrost cycle ends at the preset time or as soon as the defrost end temperature is reached. At this time, the defrost electric heater is disabled and the compressor is restarted. Series T24–3000 This model has the same operating features of Series 100 models, except for the fact that the defrost electric heater switches off at the preset time or as soon as the defrost end temperature is reached. The compressor is restarted only after the defrost time has elapsed. Series T24–6000 This version, which is similar to Series 3000 models has an auxiliary that delays the start of the fans as compared to the compressor.
