DATA RETENTION..................eeprom 100 year guaranteed on –40°C to +85°C
CONTROL SYSTEM....................8 bit/6MHz microprocessor with full hardware watch-dog
DESIGN :.......... meet EN50081/1/2,50082/1/2,60801-2,61003-1,60546-1.
EXTERNAL OVER VOLTAGE PROTECTION DEVICES , ON MAINS INPUTS, ARE
RECOMMENDED (2KV ac) TO AVOID FAILURE DURING HIGH ENERGY LIGHTENING.
5.0 PROGRAMMING INSTRUCTIONS
The table on page 7 lists the adjustable parameters. Of the three digits displayed the left is
the address parameter and the right digits are the significant value.
The 'PROGRAM MODE 'is enabled by pressing for 5 seconds at least the ‘STOP’ and ‘ACK’
push-buttons simultaneously (with the key-switch in the RESET position). In the program mode
the led 'DATA' will light. By pressing 'UP' or 'DOWN' it is possible to select the address of
automation parameters. By pressing the 'UP' ( or 'DOWN') and 'STOP' push-buttons together it
is possible to increase (or decrease) the selected parameter.
The BE32 unit is factory pre-programmed with DEFAULT parameters.
The defaults are always available by pressing simultaneously the cursors 'UP' and 'DOWN' for
two seconds at least (only in 'PROGRAM MODE ').
The data are pushed in a non volatile memory at the first transition of the KEY in ‘MAN’ or
‘AUTO’. It is recommended to check the data changing by the following : a) - put the set in
‘MAN’, b) - disconnect V battery for 30 seconds, c) - supply the BE32, d) – select ‘PROGRAM
MODE’ and check the modified data. If an error occurs, try a new programming cycle.
6.0 MAINS SIMULATED
When the JC-10 input is grounded BE32 simulates the presence of the mains.
The internal microcomputer will display an '-on' message to indicate the 'MAINS PRESENCE'.
This connection is used in applications where MAINS is not available and the user needs a
remote starting by means of an external switch, a level switch, a timer or others.
7.0 MAINS HIGH VOLTAGE
In addition to the MAINS failure due to Under Voltage (parameter 'D') or Frequency (parameters
'h'/’H’) there is a MAINS failure for HIGH voltage. The threshold is fixed to 495 Vac. The display
will show a message 'E02'. The failure will disappear as the voltage will come in the window
between 'D' and 495V.
8.0 UNDER FREQUENCY PROTECTION
The under speed protection is programmable at address 'h'. The source of the signal is the
frequency measurement of the ALTERNATOR voltage. If the frequency does not reach the
programmed threshold the BE32 will not enable the contactor of the generator. If BE32 detects
a frequency failure (with the contactor already enabled and the load transferred to the GEN-
SET) an alarm situation is generated: the alternator contactor is opened and the engine is
stopped after a cooling down timing. The display will show
'EO1' that means UNDER FREQUENCY.
9.0 MAINS AND GENERATOR CONTACTOR AUTOMATION
The coil of MAINS contactor is enabled if all three Voltage phases are between 'D' and
495Vac. The frequency must be within 'h' and 'H' values. This stability must persist for time '1'
timer (mains restore). The MAINS contactor is opened if a failure (V or Hz) is detected for 2
seconds at least. The GEN-SET will start after MAINS FAILURE TIME (channel '0') and will stop
after time '1' and '8' timers. The GENERATOR contactor is enabled in the same way but only in
'AUTO'. It will also be opened if any internal or external alarm is detected. The contactor are
enabled only if the mains and generator have the same phase sequence (ccw).
If the phase rotation is different a message -r- will appear on the display. A safe time delay of 2
seconds is inserted between GENERATOR and MAINS contactor actions.
