Manual 82384 SPM-A Synchronizer Chapter 1. General Information Regulatory Compliance • The SPM-A Synchronizer is suitable for use in Ordinary Locations per CSA and/or UL for Canada and the U.S. or non-hazardous locations only. See table below for agency listed options. -
Page 6: Description
Select the low impedance output for single-unit synchronization when the engine is controlled by a Woodward 2301A, 2500, or Electrically Powered Governor (EPG) control through a Generator Load Sensor. Use the EPG output when using a Woodward EPG control without load sensing. Both units have the following features: •... -
Page 7: Theory Of Operation
If phase and frequency are within proper limits, the synchronizer issues the breaker closure command. (Voltage is not checked in the Permissive Mode.) See Woodward Application Note 50511 for information on the prediction of the phase angle at paralleling breaker closure. Woodward... - Page 8 SPM-A Synchronizer Manual 82384 Synchronizing the Generator The phase detector compares the two signals and determines any difference between the generator and bus phases. When there is a difference, the speed bias circuit sends a correction signal to the Load Sharing and Speed Control.

CAUTION—ELECTROSTATIC DISCHARGE To prevent damage to the components of the synchronizer, read and follow the Electrostatic Discharge Awareness precautions on page ii. Set the dwell time using the four-position gang switch located in the upper left corner of the circuit board (see Figure 3-1). -
Page 21: Test And Adjustment
Manual 82384 SPM-A Synchronizer Test and Adjustment Bench Test A simple bench test may be done prior to installing the synchronizer. No adjustments can be made as a result of this test. The bench test only provides an indication of proper basic operation. - Page 22 SPM-A Synchronizer Manual 82384 Place the mode switch in the RUN position. The ENABLE indicator will be off, and the BREAKER CLOSURE contacts will be open. Place the mode switch in the OFF position. The ENABLE indicator will be off, and the BREAKER CLOSURE contacts will be open.

Page 23: Dynamic Check
Manual 82384 SPM-A Synchronizer Dynamic Check The best way to test and adjust the synchronizer is to operate it while in the CHECK mode. Place the mode switch (user supplied) in the OFF position for starting. Apply power to the electronic governor and start the engine according to the manufacturer's instructions. - Page 24 SPM-A Synchronizer Manual 82384 Phase Offset Adjustment If the synchroscope steadies at other than 0 (zero) degrees (in the CHECK mode), the phase offset potentiometer may need adjustment. Note the potentiometer position before changing the setting. Turn the potentiometer as necessary to center the indicator of the synchroscope.
