Frequently Asked Questions
What is the main difference between the Woodward EASYGEN 3200-5 (8440-1831) and the 3100-5 series?
The EASYGEN 3200-5 (P/N 8440-1831) features a front-panel graphic LCD with an interactive membrane keypad and synchroscope. The 3100-5 series is a rear cabinet-mounted variant designed without an integrated display screen, intended for remote panel interaction or SCADA control.
Does the 8440-1831 Rev. F controller support direct speed and voltage bias to electronic governors?
Yes. The controller provides two galvanically isolated analog outputs capable of delivering ±10 V, 0–20 mA, or PWM control signals directly to voltage regulators (AVR) and speed governors or engine ECUs.
How do I resolve a CAN load share communication fault on the EASYGEN 3200-5?
Check network continuity across terminals, verify that the baud rate is set identically across all connected units (typically 250 kbps or 500 kbps), and confirm that 120 Ω line termination resistors are present at both ends of the CAN bus.
Can this unit handle 480V or 600V nominal generator AC sensing directly?
Yes, the 8440-1831 accepts direct AC voltage input sensing up to 600 VAC (UL rating) without requiring external potential transformers (PTs). For systems exceeding 600 VAC, external PTs must be configured in the software setup.
