DYNACIATTM LGN Water chillers Without condenser ■ 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 (Certified BTL) as an option, enabling most CMS/ BMS to be integrated. Web server IP address 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 Remote management via web server - Setpoint 1/setpoint 2 selector: when this contact is closed, Connection to RJ port a second cooling setpoint is activated (energy storage or Connection via IP address unoccupied mode, for example) All the HMI functionalities - Power limitation: closing the contact concerned allows the available on the PC power or refrigerating consumption of the machine to be limited Simplified remote monitoring by stopping one or more compressors (this limit can be set with a parameter) - Fault reporting: this contact indicates the presence of a major fault which has caused one or both refrigerating circuits to stop - Operational status reporting indicates that the unit is in production mode. E-mail - Switch control for the customer pump, external to the machine alerts (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. ■ Maintenance Connect Touch has two maintenance reminder functions as - The scheduled maintenance reminder:when activated, standard, making users aware of the need to regularly perform this 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. A reminder message appears on the unit's HMI screen, and - The compulsory F-GAS sealing test maintenance reminder: stays there until it is acknowledged by the maintenance when activated, this function, which is the default factory operator. The information and alert relating to these functions setting, enables the period between two sealing tests to be are available on the communication bus to be used on the selected, according to the refrigerant charge, in compliance CMS/BMS. with the F-GAS regulations. 488 488 CATALOGUE 2021
