Description
Genset Current
Unbalance Limit
% 0 100 0.0
If any genset phase current differs from
the average more than this limit, it will
generate a Current Unbalance fault
condition. The action taken upon fault
condition is programmable.
If this parameter is set to 0.0 then
voltage unbalance is not monitored
Genset Current
Unbalance Action
- 0 3 0
0: no action
1: shutdown alarm
2: loaddump alarm
3: warning
Genset Reverse Power
Warning Limit
kW 0 50000 0
If the genset power is negative and
goes above this limit then a
REVERSE
POWER warning will be generated. If
this parameter is set to 0 then reverse
power fault is not monitored.
Genset Reverse Power
Loaddump Limit
kW 0 50000 0
If the genset power is negative and
goes above this limit then a
REVERSE
POWER loaddump will be generated.
Genset Reverse Power
Fail Timer
sec 0 120 5
If the genset power is negative and over
limits during this timer, a reverse power
fault will occur.
Genset Overcurrent Limit Amp 0 50000 0
If one of the genset phase currents goes
over this limit when feeding the load, this
will generate a genset overcurrent fault
condition. The action taken upon fault
condition is programmable. If this
parameter is set to 0 then overcurrent
fault is not monitored.
Genset Overcurrent
Limit-2
Amp 0 50000 0
When secondary voltage is selected, if
one of the genset phase currents goes
over this limit when feeding the load, this
will generate a genset overcurrent fault
condition. The action taken upon fault
condition is programmable. If this
parameter is set to 0 then overcurrent
fault is not monitored.
Genset Overcurrent
Limit-3
Amp 0 50000 0
When tertiary voltage is selected, if one
of the genset phase currents goes over
this limit when feeding the load, this will
generate a genset overcurrent fault
condition. The action taken upon fault
condition is programmable. If this
parameter is set to 0 then overcurrent
fault is not monitored.
Genset Overcurrent
Action
- 0 3 0
0: shutdown alarm
1: loaddump alarm
Overcurrent Time
Multiplier
0 1 64 16
This parameter defines the reaction
speed of the overcurrent detector. A
higher number means higher sensitivity.
