POWERCIATTM LX Water chillers desCRiptionoFthemainComponents ■ Remote management Connect Touch is equipped as standard with an RS485 port and an ETHERNET (IP) connection, offering a range of options for remote management, monitoring and diagnostics. Using the integrated Webserver, a simple internet connection uses the unit’s IP address to access the Connect Touch interface on the PC, facilitating everyday management tasks and maintenance operations. A range of communication protocols are available: MODBUS/ JBUS RTU (RS485) or TC/IP as standard, LONWORKS – BACNET IP as an option, enabling most CMS/BMS to be integrated Web server Adresse IP Several contacts are available as standard, enabling the machine to be controlled remotely by wired link: -automatic operation control: when this contact is open, the machine stops -setpoint 1/setpoint 2 selector: when this contact is closed, a Remote management via web server second cooling setpoint is activated (energy storage or Connection to RJ port unoccupied mode, for example) Connection via IP address Power limitation: closing the contact concerned allows the All the HMI functionalities - power or refrigerating consumption of the machine to be limited available on the PC by stopping one or more compressors (this limit can be set with Simplified remote monitoring a parameter) -fault reporting: this contact indicates the presence of a major fault which has caused one or both refrigerant circuits to stop -operational status reporting indicates that the unit is in production mode. E-mail alerts -switch control for the customer pump, external to the machine (on/off). Contacts available as an option: -setpoint adjustable via 4-20 mA signal: this input is used to adjust the setpoint in COOLING mode -power limitation adjustable by 4-20 mA signal -Second power limitation level -Power indication: analogue output (0-10 V) providing an indication of the unit’s load rate. -user fault reporting, enables integration of a fault in the water loop -general fault reporting: this contact indicates that the unit has stopped completely -alert reporting: this contact indicates the presence of a minor fault which did not cause the refrigerant circuit in question to stop. -End of storage signal: enables return to the second setpoint at the end of the storage cycle -Schedule override: closing this contact cancels the time schedule. ■ Maintenance Connect Touch has two maintenance reminder functions as - the scheduled maintenance reminder: when activated, this standard, making users aware of the need to regularly perform function enables the period between two maintenance maintenance operations and to guarantee the service life and inspections to be set. This period may be set by the operator performance of the unit. These two functions can be activated in either days, months or operating hours, depending on the independently. application. - the compulsory F-GAS sealing test maintenance reminder: A reminder message appears on the unit’s HMI screen, and when activated, this function, which is the default factory stays there until it is acknowledged by the maintenance setting, enables the period between two sealing tests to be operator. selected, according to the unit’s refrigerant charge, in The information and alert relating to these functions are compliance with the F-GAS regulations. available on the communication bus to be used on the CMS/ BMS. 460 460 CATALOGUE 2021
