CIRCUIT BREAKERS
Power to the unit must be supplied from a dedicated breaker. No other equipment should be
powered from this breaker. A tag on the motor identifies the maximum current draw of the motor.
If two units are supplied from one breaker, that breaker must be capable of handling the load of
both motors.
PUMP MOTOR
Pumps are shipped from the factory with motors wired according to the specifications given on the
order as to kind of current, frequency and voltage.
Very often on installation, it becomes necessary to change the original setting to suit the AC power
source. To do this, locate the motor change-over plate (typically located on the shaft end of the
motor) and remove the screw which secures it in place. Slide the plate so that the desired
voltage, as marked on the plate, lines up with the screw hole. Reinsert the screw and secure the
plate in place. 380 VAC pumps are permanently set and cannot be changed.
Many motor failures result from improper setting of the motor change-over plate. If set for 120
VAC and a 240 VAC feed is used, the motor will burn out after running only a short time. If set for
240 VAC and a 120 VAC feed is used, the motor will run very slowly and the starting field will soon
burn out.

PULSERS AND PULSER WIRING
A pulser is an optional device which is used when external monitoring of the dispensing unit
operation is desired. The pulser transmits one electrical signal (pulse) for each predetermined
amount of fuel dispensed. The signal is received by the external monitor (fuel management
system) which keeps a running total of the quantity of fuel being dispensed during each
transaction.
All Series 580 pulsers are operated with DC voltages. These are reed pulsers which are available
as either 1:1 or 10:1 pulses per unit of measure. The pulser type should be selected according to
the monitoring equipment, the application, and the regulations that must be met.
All Series 580 pulsers are mechanically driven by the register. The shaft which drives the pulser
does not turn during reset.
