BERNINI DESIGN BE32 User Manual

BE32 NET USER MANUAL VersionA17C
1.0 GENERAL DESCRIPTION
BE32 is a control system for STANDBY GEN-SET features 22 powerful programmable
parameters (section 10.00 and 11.02 ). Input from the GEN-SET provides visual indication for
the following:
LOW FUEL LEVEL , OVERLOAD, ALARM 1 and2 , LOW OIL PRESSURE, HIGH
TEMPERATURE (two channels), FUEL ALARM, EXTERNAL EMERGENCY STOP, ENGINE
RUNNING and REMOTE TEST.
The following parameters are measured and sampled as analogue inputs:
MAINS VOLTAGE (3-PHASE), GENERATOR VOLTAGE (3-PHASE), BATTERY VOLTAGE,
GENERATOR CURRENT (3-PHASE), GENERATOR and MAINS FREQUENCY.
These outputs are relay controlled : START, STOP SOLENOID, ALARM OUTPUT, FUEL
SOLENOID, MAINS CONTACTOR and GENERATOR CONTACTOR , GLOW PREHEAT and
'IDLE SPEED' .
For the remote transmission of alarms, and for special functions, eight static outputs are
available: 'OIL' , 'TEMP'., 'FUEL' , 'STARTING FAILURE', 'OVERLOAD FIRST LEVEL',
'ENGINE RUNNING',' BATTERY FAILURE' and 'GENERATOR VOLTAGE'.
The BE32-NET version includes RS232C interface and SENDERS interface for oil pressure
and engine temperature .
1.1 FRONT PANEL SELECTIONS
The control key switch, on the front panel, has 3 positions 'AUTO'-'RESET'-'MAN'. The key
position 'RESET' or 'MAN' of the key switch is repeated on the JB9 output connector.
1.10 'AUTO' OPERATING MODE
The timers referring to GEN-SET automation are expressed on the ch. '0' and '1' (see page 7).
These timers are activated when the voltage parameters on ch. 'D' and 'E' reach the
programmed thresholds. The GEN-SET starts in 'AUTO' for the following : MAINS voltage or
frequency failure, periodic 'START' (ch 'A' and 'B'), REMOTE TEST (input JM-10) and/or
'REMOTE START'(input JF7). All starting characteristics are specified on ch.'5'-'6'-'7'-'D'-'E'-'G'
and 'F''.
'C' is the trip level of overload protection for the GEN-SET. The first level 'c' warns to
disconnect the 'NON VITAL' loads by using JB-4 output. The GEN-SET will stop after full
MAINS restoration (or remote control restoration) or when an alarm is detected. The MAINS and
GENERATOR contactor are controlled automatically by means of the timers and thresholds .
The contactor will be enabled only if the electrical parameters VOLTAGE/FREQUENCY are
within the programmed value (ch.'D'-'E'-'H'-'h'-'L' ). If the sequences of the phase are not the
same for the mains and for the generator an alarm -r- will appear on the display. In this
condition the contactor remains disabled.
1.11 'MANUAL' OPERATING MODE
This allows the 'off-load' starting of the GEN-SET by means of the 'START' and 'STOP' push-
buttons. The load is not tranferred to the generator. To enable the GENERATOR contactor in
'MAN' the user must provide external wiring by using JB3 terminal ('GENERATOR VOLTAGE'
output).
NOTE:' ch'. means 'channel of the automation parameter'. Example: ch. 'C' is the 'C' parameter
on the automation table (see page 7).
