14 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. www.deepseaplc.com.
Registration on the website is required. This is free of charge, along with all other downloads.
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.
14.1 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.
14.2 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.
14.3 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.
14.4 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)
