Sync Time Remaining
The remaining time before the controller issues a fail to
sync warning. The fail to sync warning will cause the
Generator Management to consider this generator
unreliable and to start another generator (if available). If
the system commissioning has been performed
properly, this warning should only occur if the system is
overloaded or if there is a malfunction on this generator.
This value is only populated when the generator is
actively synchronizing (Sync Mode = Active, breaker is
open, generator is running).
Note: Early firmware versions for the Decision-Makerr
3500 controller do not support this parameter
(there is no value populated for it).
Sync Status Generator V Hz OK
This parameter indicates that the voltage and frequency
of this generator are considered to be acceptable. This
must be true before the generator will attempt to
synchronize to the paralleling bus.
This parameter is updated every 50ms, regardless of
the state of the paralleling controls.
Range: False-True
Default: False
Sync Status Voltage Matched
This parameter indicates that the average line voltage of
this generator is within the Voltage Match window of the
average line voltage of paralleling bus. This must be true
before the generator will attempt to connect to the
paralleling bus.
This parameter is only updated if the generator is
synchronizing (in either active or check mode).
Range: False-True
Default: False
222 Section 12 Paralleling System Information
Sync Status Frequency Matched
This parameter indicates that the frequency of this
generator is within the Frequency Match Window of the
bus frequency. This must be true before the generator
will attempt to connect to the paralleling bus.
This parameter is only updated if the generator is
synchronizing (in either active or check mode).
Range: False-True
Default: False
Sync Status Phase Matched
This parameter indicates that the phase angle between
this generator and the paralleling bus is within the Phase
Match Window. This must be true before the generator
will attempt to connect to the paralleling bus.
This parameter is only updated if the generator is
synchronizing (in either active or check mode).
Range: False-True
Default: False
Sync Check Matched OK
This parameter indicates that the voltage, frequency,
and phase of the generator are all within their respective
windows of the paralleling bus. This must be true before
the dwell timer will start timing. If this parameter goes
false while the dwell timer is timing, the dwell timer will
be reset.
This parameter is only updated if the generator is
synchronizing (in either active or check mode).
Range: False-True
Default: False
