The DPT35 digital counter-timer is
designed to be used with (or similar) meters and flow sensors
that produce a pulse signal. It is
typically used in water treatment
and chemical dosing applications,
most often in cooling towers and
boilers. The DPT35 serves as either
a single or a dual timer, depending
on whether one or both of its
independent accumulators and
timers are used.
When the DPT35 is used as a
single timer, the accumulator counts
the pulses coming from the meter.
When a pre-set number of pulses
has been reached, output power
turns on for a set time, and then the
cycle repeats.
For applications requiring dual
timers (typically, one chemical
feed and one water bleed), both
accumulators and timers are set to
operate independently, even though
input is from a single meter or flow
sensor. A sequential function can
be selected to lock one timer out
while the other is operating, this
prevents feed and bleed from
occurring simultaneously.
