>Repeatedly push [ ↓ ] to select the function [OEM PARAMETERS].

>Push [→], the following options will appear on the screen:

[READ PARAMETERS] [MODIFY PARAMETERS] [ENGINE TYPE]

>Push [ ↓ ] to select [MODIFY PARAMETERS]

>Push [→] to enter the GENERATOR PARAMETER sub-menu.

The video on the right will help you in carrying out a programming task. We recommend that you limit the access to the parameters by using a Password.

Adjustable Generator Parameters

ADJUSTABLE GENERATOR PARAMTERS LIST

 To select this menu, follow the instructions on the section 11.0 of the OEM manual. Use [ ↑ ] or [ ↓ ] to select a parameter. Push the [→] arrow to enter the numerical field. Push the [ ↑ ] or [ ↓ ] arrow to set a value. Push the [←] push button to return to the parameter list. When you modify a parameter, the Be126 will automatically open the menu-driven page to guide you in saving the settings.

Generator Parameters

Notes

 

UNDER VOLTAGE                       

                         320 VAC

BYPASS DELAY

                             6 sec

 

(limits 60-990V /1-15secs)

 

These parameters define operating limits for the generator voltage & frequency.

If a parameter falls below a limit, the Be124 triggers the alarm and opens the GCB.

The engine will stop after a  cooling down time (see 11.4.6).

During [BYPASS DELAY] ,Be124 ignores the alarm.

Under/V & Under/Hz work only when GCB is closed.

 

In 3-Phase mode,the Be124 monitors voltages Phase to Phase.

In Signle Phase mode the Be124 monitors VL1 to Neutral.

 

OVER  VOLTAGE                        

                  500 VAC

BYPASS DELAY

                     6 sec

 

(60-990V /1-15secs)

These parameters define operating limits for the generator voltage & frequency.

If a parameter rises above the limit, the Be124 triggers the alarm and opens the GCB. The engine will stop immediately.

In 3-Phase mode,the Be124 monitors voltages Phase to Phase.

In Signle Phase mode the Be124 monitors VL1 to Neutral.

[BYPASS DELAY] allows Be124 to ignore the alarm for a programmable time.

 

UNDER HZ                   

                        47.0 Hz

BYPASS DELAY

                          6 sec

 

(20.0-599.9Hz /1-15secs)

 

 

OVER HZ                        

                       53.0  Hz

BYPASS DELAY

                         6 sec

 

(20.0-599.9 Hz /1-15secs)

 

WARNING CURRENT                      

                             OFF

BYPASS DELAY

                           6 sec

(1-2000A /1s-15mins)

These parameters define operating limits for the generator current. If the current rises above a limit, the Be124 triggers the alarm and opens the GCB.

 

WARNING CURRENT  provides a pre-alarm only, but  SHORT CIRCUIT  will shut down                  

the engine after cooling down the generator (see 11.4.6).

 

[BYPASS DELAY] allows Be124 to ignore the alarm for a programmable time.

 

OVER CURRENT                    

                          OFF

BYPASS DELAY

                     6sec

(1-2000A /1s-15mins)

 

If the current rises above the limit for over the [BYPASS DELAY] time, the Be124 triggers the alarm, opens the GCB and stop the engine after cooling the generator.

 

SHORT CIRCUIT                      

                           OFF

BYPASS DELAY

                          0.5 sec

 

(1-2000A /0.0s-15secs)

 

 

ALTERNATOR FAIL                      

                        OFF

PHASE MODE

                     3 PHASE

[PHASE MODE] options:

[1]= single Phase Mode

[3]= 3Phase Mode

[3+CW]= 3Ph. Clock Wise

[3+CCW]= 3Ph. Counter Clock Wise

If you set  CW or CCW the engine will stop in case of wrong phase sequence. The display indicates the sequence (see 6.02)

[ALTERNATOR   FAIL]

The Be124 shutdowns the engine if Vac (or Hz) is outside of the operating range for over 150 seconds (*). This alarm works only in ‘AUTO’ or 'TEST' mode of operation.

 

(*)The 150 seconds timer starts to count when you start the engine.

 

 

KVA SHUTDOWN                         

                            OFF

BYPASS DELAY

                          30 sec

(10 -1500kVA 1s/59 mins)

If the Total Power rises above the [KVA SHUTDOWN] limit for over the [BYPASS DELAY] time, the Be124 opens the contactor and shuts down the engine after cooling the generator (see 11.4.6).

 

REVERSE POWER         

                               OFF

BYPASS DELAY

                        1 sec

(10-1500kW 1-15 secs)

If the active power of one phase becomes negative and exceeds the limit for over the [BYPASS DELAY] time, the Be124 opens the GCB and shutdowns the engine after cooling the generator.

 

PHASE UNBALANCE                   

                                OFF

BYPASS DELAY

                        15 sec

(10-990V /1-59 secs)

If the difference of voltage between phases rises above the setting for over [BYPASS DELAY] seconds, the Be124 opens the GCB and shutdowns the engine immediately.

 

EARTH FAULT                 

                            OFF

BYPASS DELAY

                      1.0 sec

(0.1-200.0A /0.3s-10.0sec)

Provides Earth Fault Protection.

The engine stops immediately.

 

(During [BYPASS DELAY], the Be124 ignores the alarm).

 

CT SIZE    L1 L2 L3                   

                             500

CT SIZE EARTH

                         0

(5-2000A / 5A)

 

It defines the size of the CTs for the phases L1-2-3 of the generator and the size of the CT for earth current monitoring. (CT size Earth Fault below 100/5 will provide 0.01A resolution)
