count cannot exceed 9000 pulses per minute. The pulse count is determined by multiplying the

flow rate (i.e., 9 gallons per minute) times the divide rate (i.e., 100 pulses per gallon). This

example would be 900 pulses per minute. Separating the AC control wires and DC pulser cables

in separate conduit will also eliminate any bleedover.

e. One Pulser, Two FMUs.

CAUTION

Power inputs (+12V) from two different FMUs or power sources to a single pulser can result in

damage to both FMUs and, possibly, the pulser. If possible, power the pulser from only one

power source. DC grounds (0V) from both sources must be joined (made common) for pulses to

be detected by both FMUs. Grounds must not

be joined (made common) unless both power

sources are 12 VDC. AC grounds are not the same as DC commons/grounds.

ATTENTION

Des entrées d'alimentation (+12 V) de deux FMU différentes sources ou de la puissance d'un

émetteur unique peut entraîner des dommages aux deux FMU et, éventuellement, le générateur

d'impulsions. Si possible, le pouvoir du pulseur d'une seule source d'alimentation. motifs DC

(0V) à partir de deux sources doivent être rejoint (en commun) pour les légumineuses à détecter

par les deux FMU. Motifs ne doit pas être rejoint (en commun) à moins que les sources

d'énergie sont de 12 VDC. AC motifs ne sont pas les mêmes que Commons CC / motifs.

Applications have been requested for one pulser in one dispenser to provide outputs to two

FMUs. When doing so, caution must be used in making pulser connections. Power inputs (+12V)

from two different FMUs or power sources to a single pulser may result in damage to the FMUs

and pulser. Power from either source will feed back to the other source and may result in

damage to both FMUs and, possibly, the pulser. DC commons/grounds (0V) from both sources

must be joined (common) for pulses to be detected by both FMUs. Grounds must not be joined

(made common) unless both power sources are 12 VDC. If the power sources are not both 12

VDC, and the grounds are not joined (common), pulses from a single pulser to two FMUs will not

be detected. AC grounds are not the same as DC commons/grounds.
