SINGLE PHASE AUTOMATIC FUEL PUMP CONTROL
WORKING MODES: OFF: all off (used with external remote switch)
MAN: the fuel level is maintained constant at MAX STOP
AUTO: the fuel level is maintained between MIN START and MAX
STOP (the pump starts when the level is lower than MIN. START and
stops at MAX STOP level)
BLOCKS: MAX ALARM: stops the pump both in manual and automatic
modes CHARACTERISTICS: - Supply voltage 12 or 24VDC
- Fuel pump engine max voltage 250Vac - Max engine current 10A
at 250Vac (6.3 A with default fuse) - Safety solenoid voltage 12 or
24V (same that supply voltage) - Max solenoid current 3A
PROTECTIONS: - 5x20mm glass fuse as protection for the pump
engine - Self-restoring integrated fuse as protection for the
solenoid - Protection against the supply voltage inversion
CONNECTIONS: J1 connector power supply 12 or 24V J2 connector
supply 230Vac J3 connector connections to level contacts J4
connector level contacts outputs (to others devices) J5 connector
fuel pump engine J6 connector remote command switch J7 connector
security fuel solenoid NOTES: In order to use a remote switch, the
internal switch must left in OFF position. The
supply inputs for the security solenoid command are pin X
(positive 12-24V) and 20 (ground 0V) of the connector J1: connect
the X pin to a positive which is present only when the engine is
running and with a proper current rate.
SIGNALLING LEDs: ON PUMP: fuel pump running MAX ALARM: level
higher than the maximum (with block) MAX STOP: maximum level (pump
stop)
MIN. START: minimum level (pump start) RESERVE: fuel reserve
EMPTY: fuel end
