INTRODUCTION
BE21 features Automatic Mains Failure (A.M.F.) and Generating Set (hereinafter GEN-SET) control and monitoring. The BE21 provides visual indication by means of LEDs and Display
Messages for the following: Fuel Level, Overload, Remote Lock, Alarm 1, Alarm 2, Low Oil Pressure, High Temperature, Mains Simulation, Periodic Test, Starting Failure, High/Low Battery voltage, Contactor status, Belt Break and Engine Running (see sections 4.0 and 5.0).
The following measurements and parameters are displayed on the front panel:
Mains/Generator Voltage, Battery Voltage, Generator Current, Generator Frequency, Charger voltage and Programmable Settings. The outputs are relay controlled (START, STOP, ALARM, FUEL SOLENOID, control of the MAINS and GENERATOR CONTACTOR).
The front panel includes pushbuttons, LEDs and a 4-digit DISPLAY (section 17.0).
OPERATING MODE selection
The operating modes are indicated by means of yellow LEDs (see section 17.0). By pushing the [MODE-DOWN] pushbutton (NOTE), it is possible to select AUTO (section 2.2), MANUAL (section 2.3) or TEST (section 2.1) operating mode. The [MODE-UP] pushbutton allows you to return to RESET. Every time the power supply is switched on, the BE21 automatically enters into RESET operating mode. The software upgrade 1.25 allows the BE21 to enter the AUTO operating mode automatically (see section 21.0).
NOTE: The effect of the [MODE-DOWN] [MODE-UP] pushbuttons is delayed for 1 second, in order to avoid unwanted selection of the operating mode. The BE21 does not allow operating MODE selection during the STOP procedure ([MODE-DOWN] and [MODE-UP] are inhibited)
>TEST< operating mode (use [MODE-DOWN] pushbutton to enter this mode)
The TEST operating mode tests the GEN-SET. The BE21 starts the engine according to the programmed parameters (section 12.0, Ch.14-17) and transfers the load to the GEN-SET (see parameter [Ch.29] for the available options). The BE21 stops the engine in ‘AUTO’ operating mode (if the Mains is within the programmed settings) or in MANUAL operating mode (by using the [STOP] pushbutton). If you push the [STOP] pushbutton, ‘ALARM2’ will energize. To clear the alarm, select the ‘RESET’ operating mode (section 2.4).
>AUTO< operating mode (use [MODE-DOWN]/[-UP] pushbuttons to enter this mode)
The engine starts if the Mains fails, (Automatic Mains Failure) according to the Ch.0/1/2/3 parameters (section 12.0). The contactor of the MAINS opens, and the contactor of the GENERATOR (KG) closes (after the warm-up time) (Ch.4) if the Voltage and Frequency are within the settings (Ch.6/7/8/9). If the Mains restores (Ch.1), the contactor of the GENERATOR opens, and the contactor of the MAINS closes (after a 2 second delay). The Engine will stop after a cooling down time (Ch.5). In case of alarm, the KM closes after the STOP cycle independently of the Mains status. In ‘AUTO’ operating mode, the BE21 periodically tests the engine if the channels '26' and ‘27' have been programmed (section 22.0). During the periodic test, the yellow LEDs indicating the AUTO operating mode will continue to blink. The starting characteristics are programmed in the channels ‘14’ to ’17‘. Channel '11’ provides overload protection for the GEN-SET against Over Current (the protection is delayed by 6 seconds). In 'AUTO' operating mode, the BE21 monitors the status of the JC5 'Input 1' terminal, (according to the setting of the channel '22' (see sections 8.0 and 12.0).
>MANUAL< operating mode (use [MODE-DOWN]/[-UP] pushbuttons to enter this mode)
The MANUAL operating mode allows ‘Off-Load’ use of the Engine by means of the [START] and [STOP] pushbuttons. To start the engine, push the [START] pushbutton until engine starts (the display shuts down during the start pulse, see section 21.0). To stop the engine, push the [STOP] pushbutton until the [StOP] message appears on the display. If the engine has already stopped, it is possible to clear the 'STOP-cycle' by pressing the [STOP] pushbutton. The BE21 does not transfer the Load to ‘MANUAL’ operating mode. (To control manually the contactors see the section 22.0).
>RESET< operating mode (use [MODE-UP] pushbutton to enter this mode)
This operating mode clears the fault alarms and enters the parameters for programming or reading (sections 6.1 and 6.3). If the BE21 stays in 'RESET' operating mode for more than 5 minutes, the Display and LEDs are turned off automatically. A dot on the display will begin to blink slowly (see section 3.0). Push one of the pushbuttons on the front panel to restore the Display and LEDs operating mode.
