15 DSE 4 STEPS TO SUCCESSFUL SYNCHRONISING
Synchronising and load sharing is often considered to be a complex subject. In fact, it is very simple when
broken down into smaller steps.
After following the Commissioning section of this manual, the 4 Steps must be followed before any parallel
operation is attempted.
The following information is a short form guide only, intended as a memory jogger once the steps are fully
understood.
The full video presentation of the 4 Steps is available on the DSE website.

This page is also available as a training document (handout style) from DSE. Part Number 056-001 Four Steps
to Synchronising – included on the DSE website.
15.1 CONTROL
Check the control of the engine is working:
•
Control of AVR
•
Control of Governor
•
Direction of Control
Failure of the above steps will result in poor control of the governor/AVR leading to problems during
synchronising and/or load sharing if not corrected.
15.2 METERING
•
CTs on the Right Phase
•
CTs in the Right Direction
Failure of the above steps will result in incorrect power factor and kW calculations leading to problems
load sharing if not corrected.
15.3 COMMUNICATIONS
•
All Modules Connected on the MSC Link
•
Re-Calibrate, Sync + Load Control, Multi-Set
•
Remove One MSC Plug
Failure of the above steps will result in the controllers being unable to communicate leading to
problems during synchronising and/or load sharing if not corrected.
15.4 SYNC CHECKS
•
Use the Built in Sync Scope to Determine Correct Phase Wiring
•
Phase Checks across the Breaker.
Failure of the above steps will result in serious damage to the system (breakers, bus bars, alternators,
engines etc)
