Exact digital time setting

Dual counter/timer with optional sequential operation

Plug-in outputs and power cord for convenience in cooling tower applications



The PT35 digital counter-timer is designed to be used with Seametrics (or similar) meters and fow 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 PT35 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 PT35 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 fow 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.

The PT35 can be used with dry contact meters, contact-ing-head meters with solid-state pickups (Seametrics MJE
meters), or insertion fow sensors (Seametrics IP, TX, and EX series).
