If this LED is turned on, verify that the fans in the power supply chassis are turning and free of dust and

other obstructions, and that the temperature around the power supply is less than 55 °C. If the power

supply is cooled down without delay, it can recover from this situation without shutting down. This LED

will turn off once the internal power supply heat sink temperature falls below approximately 90 °C.

POWER SUPPLY FAULT LED—This red LED turns on when one of the supply’s three power converters

has shut down or one or more of the supply levels is below internally specified levels. If this LED is on,

check for a short circuit on external devices connected to the control’s power supply.

When the short circuit has been removed, the supply will resume normal operation (Note that if the 24 V or 5 V outputs

are shorted, these power converters will be latched OFF and can only be cleared by removing the shorted

condition and removing the input power for 1 minute (or until the front panel LEDs extinguish). If no short

circuit is found, reset the supply by removing input power for one minute. If the power supply is still not

functioning after input power has been restored, verify that the supply is properly seated to the

motherboard connector. If the supply is properly seated but is not working, then replace the supply.

Simplex Power Supply Checks

The following is a troubleshooting guide for checking areas which may present difficulties. If these checks

are made prior to contacting Woodward for technical assistance, system problems can be more quickly

and accurately assessed.

• Is the input power within the range of the control’s power supply input?

• Is the input power free of switching noise or transient spikes?

• Is the power circuit dedicated to the governor only?

• Are the control’s supplies indicating that they are OK?

• Are the control’s supplies outputting the correct voltage?

• Is the RTN / CPU Low Vcc LED ON?
