D-700 MK3 User Manual Firmware V-16.8
- 122 -
When a genset closes to the Busbar, if
the mater genset controller does detect
the Busbar voltage at the expiration of
this period, a “BUSBAR FAIL” fault
condition will occur.
This is the delay after all generators
close to the busbar and before the
master genset controller acknowledges
“Busbar ready” signal.
Multi Load Subtract
Power Level
When the genset active power goes
over this limit, the controller will start
substracting load as described in
chapter Five Step Load Management.
Multi Load Add Power
Level
When the genset active power goes
below this limit, the controller will start
adding load as described in chapter
Five Step Load Management.
Multi Load Substract
Start Delay
If the load stays over the Multi Load
Substract Power Level parameter
during this timer, then 1 step of load is
substracted.
Multi Load Substract
Wait Delay
This is the minimum period between
two load subtract operations.
Multi Load Add Start
Delay
If the load stays below the Multi Load
Add Power Level parameter during this
timer, then 1 step of load is added.
Multi Load Add Wait
Delay
This is the minimum period between
two load add operations.
Excess power Warning
Limit
If the genset active power goes above
this limit then the controller will give an
Excess Power Warning.
Earth Current
Transformer Primary
This is the rated value of current
transformers at the earth CT inputs.
Earth Current Alarm Limit
If earth current goes over this limit when
feeding the load, this will generate a
overcurrent fault condition.
Earth Current Alarm
Level
Earth Current Fault Delay
If earth current is over the limit during
this timer, earth current alarm will occur.
If any of the phase currents is over the
limit during this timer, an overcurrent
fault will occur.
If any genset phase voltage differs from
the average more the limit during this
timer, it will generate Voltage
Unbalance fault condition.
