CHAPTER 4: FUNCTIONALITY

A 6% voltage unbalance equates to a roughly 25% current unbalance and will frequently cause motor damage.

•LdLoss Setup (load loss setup): Load loss is based on watts, defined as follows:

watts = 1.732 ⋅ average current ⋅ voltage ⋅ power factor

(EQ 4.3)

The power factor is determined using the phase relationship between voltage and phase C current readings. Full load would be when the average current is at FLA, voltage is at nominal value, and power factor equals 0.85. This would equate to a load loss level of 100%. The LdLoss Setup Fault trip point is programmable as a percentage of this value. The motor would need to drop below this level for the preset time to cause the load loss fault. The relay is shipped with this option disabled.

The time delay settings are described below.

•AuxSns1 and AuxSns2 (auxiliary sense failure): Should the LM10 detect that a contactor did not open/close according to its command, an auxiliary sense (AuxSns) trip failure will be recorded in the fault record and shut down the run relay. This fault is factory preset at 0.4 seconds. The delay time for closing the relay can be changed however opening time is set at a constant 0.4 seconds to detect contact welding.

Applications requiring a delay between the run command and the starter pulling-in can be accommodated using this feature (for example, fans requiring damper closer before running). The AuxSns1 and AuxSns2 time delays can be set to match the damper closure time.
