Introduction
Use this calibration procedure after a Load Sharing Module is installed on a generator set, to obtain the needed operating characteristics during load sharing.1. Check that the proper voltage is connected to terminals 15(+) and 16(-). Proper polarity must be maintained. See the plant wiring diagram, Figure 1-3.2. Remove wires from load sharing line terminals 10 and 11, and from the SPM-A Synchronizer (if used) at terminals 24 and 25.3. Select isochronous operation by shorting terminals 13 and 14.4. If a speed setting potentiometer is used, set it to mid position 50%.
- START-UPBe prepared to make an emergency shutdown when starting the engine, turbine, or other type of prime mover, to protect against runaway or overspeed with possible personal injury, loss of life, or property damage.
5. Start the engine according to the engine manufacturer's instructions. Adjust the engine for rated speed. Apply full load to the generator set. NOTEThe most accurate calibration is made at full load. However, if it is not possible to run the generator set at full load, run it at less than full lad, and reduce the voltage readings given in this calibration procedure proportionally. For example: run a 200 kW generator set at 100 kW and divide all voltages given in this calibration procedure by 2. If you reduce the load in this manner, be sure to reduce it by the same
