When the LSM is active with breaker closure [connection of terminal 13 to 14],

then the LSM seeks to equalize its generator percent of load with the average presented on the load share line.

The AGLC provides a ramping of the individual generator relative to the average on the load share line.

The LSM creates an offset up or down to match its percent loading to that of the generator average.

When this is achieved, the LSM output should again be at it normal 2.5 Vdc.

The output bias and load share signals are low power and very susceptible to influence by induced voltage.

Please check shielding and proper grounding.

The speed pot creates and output offset,

so its condition and resolution are critical.

A quality multi-turn pot is typical.

Table 4-3 gives the maximum overload

protection for supply mains connected to any single or redundant pair of MicroNet Plus main power

supplies. It is not recommended that both MicroNet Plus main power supplies of a redundant pair be

connected to a single source, since failure of that source would disable the system.

Multiple chassis systems using MicroNet Plus power supplies may have power supplies of the same

model, but in different chassis, connected to the same source. In this case, each branch to a chassis

must have its own overcurrent protection sized according to Table 4-3. and the power source must be

sized for the sum of the branches.

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.
