Woodward 9908-363 LSOV25 Liquid Fuel Shutoff Valve

In the event that on supply needs to be replaced, the recommended method for changing

Power Modules is with the power off (to the module being removed and the module being inserted).

The system will tolerate this “cold swap” method without failure.

Each main power supply has four LEDs to indicate power supply health (OK, Input Fault,

Overtemperature, and Power Supply Fault).

See MicroNet Plus Power Supply Troubleshooting (Section 5.5) for a description of the LED indications.

Input power connections are made to the power supply through a plug/header assembly on the front of

the power supply.

For redundant operation, the control can use any combination of power supplies.

The power supplies can only be installed into slots PS1 (power supply #1) and PS2 (power supply #2). If

redundant power supplies are not needed, blanking plates must be installed in the slots not being used.

Branch circuit fuses, circuit breakers, and wiring must meet appropriate codes and authorities having

jurisdiction for the specific country (CE, UL, etc.). See Table 4-3 for maximum recommended fuse or

breaker ratings. Do not connect more than one main power supply to any one fuse or circuit breaker. Use

only the wire sizes specified in Table 4-3. which meet local code requirements. Time delay fuses or circuit

breakers must be used to prevent nuisance trips.
