1.0 INTRODUCTION
The Pulse EP2100 Series controllers offer a high level of flexibility in controlling water treatment
applications.
•There are four slots that accept a variety of Input/Output Modules, which provides unparalleled versatility. Dual sensor
input modules are available that are compatible with a variety of sensors (two sensors per module):
»Contacting conductivity
»Electrodeless conductivity
»pH
»ORP
»Any Pulse disinfection sensor
»Generic sensor (Ion Selective Electrodes or any type of sensor with a linear voltage output between -2 VDC
and 2 VDC)
•Three analog (4-20 mA) input modules with two, four or six input circuits is also available for use with 2,3 or
4-wire transmitters.
•Two other modules feature two or four isolated analog outputs that may be installed to retransmit sensor input signals
to a chart recorder, datalogger, PLC or other device. They may also be connected to valves, actuators or metering
pumps for linear proportional control or PID control.
•Another module provides two corrosion sensor inputs.
•Sixteen Virtual Inputs are configurable in the software, to either allow for calculations based on two real inputs, or to
allow to compare values from two sensors to provide redundancy.
•Eight or Twelve relay outputs may be set to a variety of control modes:
»On/Off set point control
»Time Proportional control
»Pulse Proportional control (when purchased with Pulse solid state opto outputs)
»Flow Proportional
»PID control (when purchased with Pulse solid state opto outputs)
»Lead/Lag control of up to 6 relays
»Dual set point
»Timer
»Bleed or Feed based on a Water Contactor or Paddlewheel flow meter input
»Feed and Bleed
»Feed and Bleed with Lockout
»Feed as a percent of Bleed
»Feed as a percent of elapsed time
»Daily, Weekly, 2-week or 4-week Biocide timers with pre-bleed and post-add lockout of bleed
»Intermittent sampling for boilers with proportional blowdown, controlling on a trapped sample
»Always on unless interlocked
»Probe Wash timer
»Spike to alternate set point on timed basis
»Target PPM
»PPM Volume
»Dual Switch
»Boolean Logic
»Diagnostic Alarm triggered by:
•High or Low sensor reading
•No Flow
•Relay output timeout
•Sensor error
Relays are available in several combinations of powered relays, dry contact relays, and pulse solid state opto relays.
Sixteen virtual Control Outputs are congurable in the software, using most of the possible relay or analog output control
algorithms, that may be used to interlock or activate actual control outputs.

Auxiliary DC power option boards, available with either 12 or 24 VDC, may be added to support high-wattage trans-
mitters or ancillary devices such as cell modems by supplying up to 10 watts of power.
The standard Ethernet feature provides remote access to the controller’s programming via a PC connected directly, via
a local area network, or via Fluent account management server. It also allows emailing of datalog files (in CSV
format, compatible with spreadsheets like Excel) and alarms, to up to eight email addresses. The Modbus TCP and
BACnet remote communications options allow communication with PC-based applications, HMI/SCADA programs,
Building Energy Management systems, Distributed Control Systems (DCS), as well as stand-alone HMI devices.
Two optional WiFi cards are available, one which allows simultaneous Ethernet and WiFi communications, and one
that increases security by disabling Ethernet when WiFi is enabled. The WiFi can be set to Infrastructure Mode to
provide all the Ethernet functions above, or Ad-Hoc Mode to allow access to the programming wirelessly.
Our USB features provide the ability to upgrade the software in the controller to the latest version. The Config file
feature allows you to save all the set points from a controller onto a USB flash disk, and then import them into another
controller, making the programming of multiple controllers fast and easy. The data logging feature allows you to save the
sensor readings and relay activation events to a USB flash disk.
