Page 12: Easygen Connected To Gcp/Mfr (Can)
Manual 37442B LSG - Load Share Gateway easYgen connected to GCP/MFR (CAN) The easYgen devices communicate via CAN bus among each other with an easYgen specific protocol which dif- fers from the GCP/MFR protocol. The LSG is able to connect GCP/MFR and easYgen devices in a single load share network on the same CAN bus. -
Page 13: Easygen Connected To Legacy Device (Can/Analog)
Manual 37442B LSG - Load Share Gateway easYgen connected to legacy device (CAN/Analog) The easYgen devices communicate via CAN bus among each other and therefore can´t communicate directly to analog legacy devices which have no CAN bus interface. The LSG is able to connect analog legacy devices and easYgen devices in a single load share network. -
Page 14: Figure 2-4: Application - Analog Active And Reactive Power
Manual 37442B LSG - Load Share Gateway Active and reactive power loadshare: On CAN (easYgen) the LSG for active power loadsharing is fixed to work as generator with address 16 the LSG for reactive power loadsharing to work as generator with address 15. For this reason it is not allowed, to set any easYgen to address 15 or 16. -
Page 15: Figure 2-5: Application - Analog Active Power
Manual 37442B LSG - Load Share Gateway Examples B: Active power loadshare: On CAN (easYgen) the LSGs are fixed to work as generator with addresses 15 and 16. For this reason it is not al- lowed, to set any easYgen devices to address 15 and 16. -

Manual 37442B LSG - Load Share Gateway Half-Duplex on RS-485 Figure 4-5: RS-485 - connection for half-duplex operation NOTE Please refer to EGCP-2 manual 26076 / 26174 „Installation and Operation – Chapter 3. Electrical Instal- lation and Specifications”. This manual describes how the bus needs to be terminated. Is the LSG at the end of the RS-485 bus, a terminating resistor of 120 ohm needs to be connected to the Sub-D connector. -
Page 22: Can Bus Interface
Manual 37442B LSG - Load Share Gateway CAN Bus Interface The CAN baud rate is detected automatically. For the supported baud rates please refer to „Maximum CAN Bus Length“, Page 23. Figure 4-6: CAN bus - overview Terminal Description not connected... -
Page 23: Figure 4-7: Interfaces - Can Bus - Termination
• The configured baud rate is too high for wiring length • The CAN bus cable is routed in close proximity with power cables Woodward recommends the use of shielded, twisted-pair cables for the CAN bus (i.e.: Lappkabel Unitronic LIYCY (TP) 2×2×0.25, UNITRONIC-Bus LD 2×2×0.22). -
Page 24: Bus Shielding
Manual 37442B LSG - Load Share Gateway Bus Shielding All bus connections of the LSG are internally grounded via an RC element. Therefore, they may either be grounded directly (recommended) or also via an RC element on the opposite bus connection. -
