L/PULSE parameters allow you to set
the characteristics of the meter. The
TIMEOUT parameter considers the
maximum interval between
subsequent pulses.
When the pump receives an external
input signal sending pulses, it doses
the liquid based on the concentration
value of the liquid and millimetres
per quintal (MLQ)
destination. The PULSE/L
L/PULSE parameters allow you to set
the characteristics of the meter. The
TIMEOUT parameter considers the
maximum interval between
subsequent pulses.
When the pump receives a pulse
input signal, it adjusts the flow rate
based on the value of pulses per
minute received between
maximum and minimum values. The
TIMEOUT parameter considers the
maximum interval between
subsequent pulses.
The pump adjusts the flow rate
based on an external analog signal
and the maximum and minimum
values set in the inputs.
The pump adjusts the flow rate
based on an external analog signal
and the maximum and minimum
values set in the inputs.
The pump alternates pause periods
with constant flow rate operation
periods whose duration can be set.
