Master and Slave Control Capabilities
The 8440-1945 supports master/slave control. This feature allows multiple generators to work together. One unit acts as the master. The others follow as slaves. Consequently, you can parallel several gensets easily.
Moreover, this controller works in both mains parallel and islanded operations. For grid-connected sites, it synchronizes with utility power. For remote sites, it runs independently as an island. This flexibility makes the 8440-1945 suitable for diverse projects.
Expansion and Connectivity Features
The 8440-1945 includes analog I/O and discrete expansion board connectivity. You can add more inputs or outputs as needed. However, remember that this P1 model has fewer built-in interfaces than P2 versions. Plan your I/O requirements before installation.
Typical connections include generator voltage inputs, current transformer inputs, and remote control signals. Since the unit has no local display, all monitoring and control happen through a remote panel or SCADA system.
Frequently Asked Questions (FAQ)
1. Why does the 8440-1945 have no LCD screen?
The 8440-1945 uses a sheet metal frame design without a built-in display. Woodward designed this model for remote operation only. You must use an external HMI or PC for configuration.
2. Can I use the 8440-1945 for a single generator without mains?
Yes, select the “GCB” or “none” application mode. The 8440-1945 works perfectly for islanded single-generator sites.
3. What is the difference between the 8440-1945 and a P2 series model?
P2 models have more I/O ports and connector options. The 8440-1945 (P1) has fewer interfaces and no LCD. However, it costs less and fits smaller cabinets.
4. How do I configure the 8440-1945 without a screen?
You need Woodward’s configuration software and a PC connection. Connect via the rear communication port. Then set all parameters remotely.
5. Does the 8440-1945 support auto mains failure (AMF)?
Yes, when you select modes like GCB/GGB/L-MCB, the 8440-1945 provides full AMF functionality. It starts the generator automatically upon mains failure and transfers loads.
