LED Indicators

The Woodward 5503-335 has ten LEDs on the front faceplate.
These LEDs provide at-a-glance status monitoring for operators.
The TX/RX LED indicates transmit and receive activity.
LINK shows Ethernet connection status.
STANDBY indicates standby mode operation.
SYSCON shows system controller status.
RUN confirms normal processor operation.
IOLOCK indicates an I/O lock condition in the VMEbus or CPU.
LVCC monitors logic voltage supply status.
WATCHDOG confirms watchdog timer operation.
CAN #1 and #2 show communication activity on each CAN port.
The FAULT LED lights red to indicate a CPU fault with flashing.

System Requirements

The Woodward 5503-335 must be used with an expansion chassis.
This chassis requires a Remote RTN module for proper operation.
As a CPU-based system, it cannot function standalone.
VMEbus backplane connectivity is essential for I/O expansion.
Therefore, plan your system architecture before purchasing the 5503-335 .

Installation Guidelines

First, mount the Woodward 5503-335 in a compatible MicroNet chassis.
Ensure the expansion chassis includes a Remote RTN module.
Insert the module firmly into the VMEbus backplane slot.
Secure the module with front panel retaining screws.
Connect all required communication and I/O cables.
Verify the operating temperature stays within 0 to +55°C.
Keep the installation altitude below 4000 meters.
Ensure adequate airflow around the module for cooling.
Do not exceed IP20 protection rating for environmental exposure.
After installation, check all ten LED indicators for proper status.
