Description

(2)

Current Transformer

Ratio

500

This is the rated value of the current transformer.
The secondary of the transformer will be 5 Amps.

(2)

Overcurrent Limit

If the current goes above this limit, during

Overload

Timeout

then a

Overcurrent Load Dump

alarm will be

generated. If this parameter is 0 then Overcurrent check
is disabled.

(2)

Power x 3

If this parameter is set to 1, then the power read from
the genset phase will be displayed as multiplied by 3.

(2)

Excess Power Limit

If the active power goes above this limit, during
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.

(2)

Genset Voltage Low

Limit

170

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

GENSET

LOW VOLTAGE

alarm

and the engine will stop.

(2)

Genset Voltage High

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.

(2)

Low Battery Voltage

Warning

9.0

If the battery voltage falls below this limit, this will
generate a

LOW BATTERY

warning.

(2)

High Battery Voltage

Warning

31.0

If the battery voltage goes over this limit, this will
generate a

HIGH BATTERY

warning.

(2)

High Battery Voltage

Shutdown

33.0

If the battery voltage goes over this limit, this will
generate a

HIGH BATTERY

shutdown

alarm and the

engine will stop.

(1)

Mains Waiting Timer

min

0.5

This is the time between the mains voltages entered
within the limits and the generator contactor is
deactivated.

(2)

Genset Contactor Timer

sec

This is the period after the mains contactor has been
deactivated and before the generator contactor has been
activated.

(2)

Mains Contactor Timer

sec

This is the period after the generator contactor has been
deactivated and before the mains contactor has been
activated.

(2)

Reverse power warning

limit

If the genset power is negative and goes above this
limit then a

REVERSE POWER

warning will be

generated.

(2)

Reverse power

loaddumpg limit

If the genset power is negative and goes above this
limit then a

REVERSE POWER

loaddump will be

generated.

(2)

Load Shedding Low

Limit

If the genset power goes below this limit then the load
shedding relay will be deactivated.

(2)

Load Shedding High

Limit

If the genset power goes above this limit then the load
shedding relay will be activated.
