Fault Handling:
Idle channels must be terminated with jumpers (voltage input to 0.5V, current input to a shunt) to prevent false alarms due to floating signals.
Do not connect non-equivalent modules in series; output voltage tolerance must be ≤±2%.
Firmware and Configuration: Configuration updates are performed using the Woodward ToolKit service tool, enabling remote diagnostics in conjunction with the RP-3500 remote panel.
