Table 7.01A - Mains Failure Control Note: [ xx " ] = seconds, [ xx ' ] = minutes, [xxh ] = hours
Parameter Code & Description
Mains Contactor Control (KM). If the Mains Failure persists for more than [P.0]
(seconds or minutes), the Mains contactor will open and the [P.1] timer will start to
count. The Mains contactor will close only after the [P.2] timing.
Mains Failure time. After the [P.0] timing (see above), the engine will start if the
Mains Failure persists for the [P.1] time.
Mains Restore time. The Be242 transfers the Load to the Mains once the MAINS
is stable for at least [P.2] (seconds, minutes or hours). During [P.2], the engine will
continue to run ON-LOAD. After [P.2], the [P.24] timer will take place to run the engine
OFF-LOAD (the contactor of the generator will open).
NOTE: WHEN VOLTAGE OR FREQUENCY IS OUTSIDE LIMITS, THE GREEN INDICATORS BLINK
SLOWLY. DANGEROUS VOLTAGE MAY BE PRESENT IN THE CONTROLLER EVEN IN CASE THE
INDICATORS ARE OFF
Table 7.01B - Mains Failure Control Note: [ xx " ] = seconds, [ xx ' ] = minutes, [ oFF ] = disabled
Parameter Code & Description
Contactors changeover. This timing introduces a delay
between the switching of the contactors.
Undervoltage limit. If the Phase-to-Phase voltage falls
under this limit, the [P.0] timer will energize.
Overvoltage limit. If the Phase-to-Phase voltage rises
above the limit, the [P.0] timer will energize.
UnderHz limit. If the Phase-to-Phase frequency falls
under the limit, the [P.0] timer will energise.
OverHz limit. If the Phase-to-Phase frequency rises
above the limit, the [P.0] timer will energise.
Phase Selection. It allows 3-Phase or Single Phase control
of voltages and currents. The following options are available:
[0] 3 Phase V Mains & 3 Phase Generator
[1] 3 Phase V Mains & 1 Phase Generator
[2] 1 Phase V Mains & 3 Phase Generator
[3] 1 Phase V Mains & 1 Phase Generator
