Description

(2)

Current Transformer

Ratio

500

This is the rated value of current transformers.
All transformers must have the same rating.
The secondary of the transformer will be 5 Amps.

(2)

Overcurrent Limit

If the current goes above this limit, during the period
defined in

Overload Timeout

then a

Overcurrent Load

Dump

alarm will be generated.

If this parameter is 0 then Overcurrent check is disabled.

(2)

Excess Power Limit

If the active power goes above this limit, during the
period defined in Overload Timeout then an

Excess

Power Load Dump

alarm will be generated.

If this parameter is 0 then Excess Power check is
disabled.

(2)

Overload Timeout

sec

This is the period between the current or active power go
over the limits and

OVERCURRENT

EXCESS

POWER

Load Dump alarms occur.

This is also the period between the frequency goes out
of the limits and

OVERSPEED

UNDERSPEED

alarms

occur.
This is also the period between the genset voltage goes
out of the limits and

HIGH VOLTAGE

LOW

VOLTAGE

alarms occur.

(1)

Mains Voltage Low Limit

170

If one of the mains phases goes under this limit, it
means that the mains are off and it starts the transfer
to the genset in

AUTO

mode.

(1)

Mains Voltage High Limit

270

If one of the mains phases goes over this limit, it
means that the mains are off and it starts the transfer
to the genset in

AUTO

mode.

(2)

Mains Frequency Low

Limit

If the mains frequency goes under this limit, it means
that the mains are off and it starts the transfer to the
genset in

AUTO

mode.

(2)

Mains Frequency High

Limit

If the mains frequency goes above this limit, it means
that the mains are off and it starts the transfer to the
genset in

AUTO

mode.

(2)

Genset Low Voltage

Shutdown Limit

180

If one of the generator phase voltages goes under this
limit when feeding the load, this will generate a

GENSET

LOW VOLTAGE

shutdown alarm

and the engine will

stop.

(2)

Genset Low Voltage

Warning Limit

190

If one of the generator phase voltages goes under this
limit when feeding the load, this will generate a

GENSET

LOW VOLTAGE

warning.

(2)

Genset High Voltage

Warning Limit

260

If one of the generator phase voltages goes above this
limit when feeding the load, this will generate a

GENSET

HIGH VOLTAGE

warning.

(2)

Genset High Voltage

Shutdown Limit

270

If one of the generator phase voltages goes over this
limit when feeding the load, this will generate a

GENSET

HIGH VOLTAGE

alarm and the engine will stop.
