  • Page 8: Safety Instructions

    2 Safety instructions This operating manual is part of the device. It must be kept in the vicinity of the controller as well as for future use so that it can be consulted when required. The operating manual must be available to the operating and maintenance personnel at all times in order to avoid operating errors.

  • Page 9: Disclaimer In The Event Of Non-Compliance

     WARNING Warning of damage to goods! In our experience, the transmission of fault messages is not yet functional during the putting into service (no internet connection, no telephone line installed, etc.). It is strongly recommended in such cases to monitor the controller via the CAN bus using a system centre, a store computer or an operator terminal and to enable the transmission of fault messages, for example using a GSM modem via a mobile telephone system.

    9 Operation of WRG 3010 E The WRG 3010 E controller for heat recovery can only be operated and parametrised with the PC software LDSWin. The connection of LDSWin to the system centre (that functions as gateway for the controller) can either be made remotely (via modem or via the network) or directly on-site (via a serial connection): ...
  • Page 92 If a WRG 3010 x or GLT x010 has been connected in the E*LDS system via the CAN bus, the entry "BMS" is displayed in the menu bar in LDSWin:  If this entry is missing, then either the controller has not been detected by the system centre or the dongle does not have rights as "BMS project engineer".
