1.0 INTRODUCTION
The Evapco
Pulse~
Pure Integrated Controller offers conductivity control of evaporative cooling water
integrated into Evapco’s patented water treatment system. This addendum should be used in
conjunction with Evapco’s standard
Pulse
~Pure
®
Installation, Operation, and Maintenance Manual.
The
Pulse~
Pure Integrated Controller is microprocessor-driven with on/off control outputs. It is
supplied with a temperature compensated toroidal conductivity sensor and associated mounting
assembly for the sensor. Set points and operating parameters may be viewed without interrupting
control. Each set point change will take effect as soon as entered.
The Timer output is scheduled on a user selectable daily, weekly, two week or four week recurring
cycle. It may be programmed for one cycle per day (in weekly, two week or four week cycle) or up to
10 times per day (in daily cycle). The Timer output is equipped with a pre-bleed and bleed lockout
feature.
All control outputs are interlocked with a flow input via the X-1 connector on the
Pulse
~Pure circuit
board. An alternative arrangement allows only the blowdown and timer relays to be interlocked with
flow while the
Pulse
~Pure chamber is continuously energized.
Our unique USB feature provides the ability to:
1.
Export Config file to a standard USB flash stick to save all controller set points and load settings
into another controller.
2.
Download the last 2 months of data including, conductivity, temperature, water use (if
equipped with optional water meters), and
Pulse
~Pure status onto a standard USB flash disk.
