About the EnviroRanger
About the EnviroRanger ERS 500…
The EnviroRanger is intended for advanced water and wastewater
applications. This device can handle virtually all of your pump control and
level monitoring needs –often replacing expensive PLCs and integrating into
a SCADA system for a fraction of the cost of competitive systems.
The EnviroRanger is programmable.
It can be configured for nearly any water or wastewater application, control
up to five pumps, gates, or alarms –and can communicate its status by way
of direct serial connection, modem, or industrial communication network.
The EnviroRanger is flexible.
It can take discrete input from pumps or other devices to modify its
operation, and can also time events to maximize efficiency or minimize cost.
The EnviroRanger is upgradeable.
Its basic features can be further enhanced with any of the following:
Hardware Upgrades
•mA I/O Analog Cards
•RS-485 Communication
•RAM Memory
•Discrete Inputs
Software Upgrades
•Dual Point
•Data Logging

About Configuring ERS 500 Parameters…
The primary configuration of the EnviroRanger uses Milltronics Dolphin
Plus software and a serial connection to the device.
Configuring the EnviroRanger with the optional Hand Programmer is also
possible. This method is not recommended for complex installations.
As a rule of thumb, if your application falls into one of the pre-configured
applications outlined in the EnviroRanger User Guide, then use the hand
programmer. If your application is more complex, we suggest you use
Dolphin Plus. To purchase a copy of Dolphin Plus, contact your Milltronics
representative.

About the EnviroRanger
About EnviroRanger Communication Systems…
The EnviroRanger is an integrated level and pump controller that
communicates component and system status to a Supervisory Control and
Data Acquisition (SCADA) system, using a serial device such as a radio
modem, leased line, or dial up modem.
The standard ERS 500 supports the following two communication protocols:
Dolphin
Dolphin is a proprietary Milltronics protocol designed to be used with Dolphin
Plus. For more information on Dolphin Plus, or to obtain a copy of the
software, contact your Milltronics representative.
Modbus
Modbus is an industry standard protocol used by SCADA and HMI systems,
and uses the EnviroRanger’s RS-232 ports to communicate. For a description
of the Modbus protocol, contact your local Schneider representative.
Optional SmartLinx®cards
The standard EnviroRanger unit may also be enhanced with Milltronics’
SmartLinx®communication modules that provide an interface to popular
industrial communication systems.
This manual only describes the built-in communications. For more
information on SmartLinx, please consult the appropriate SmartLinx manual.

Wiring Guidelines
•The maximum length for RS-232 is 15 meters (50 feet)
•The RJ-11 cable maximum length is 3 meters
•RS-485 maximum length is 1,220 meters (4,000 feet)
•Use 24 AWG (minimum)
•Use good quality communication grade (shielded twisted pairs) cable that is
recommended for RS-232 for ports 1 and 2
•Run the communication cable separately from power and control cables. (Do
not tie wrap your RS-232 or RS-485 cable to the power cable or have them
in the same conduit.)
•Use shielded cable and connect to ground at one end only
•Follow proper grounding guidelines for all devices on the bus
Improper wiring and incorrect choice of cables are two of the most common
causes of communication problems.

Port 1: RS-232 RJ-11 Jack
The RJ-11 port is inside the enclosure of the Wall mount, and on the face
of the rack and panel units (see below).

Installation
To connect the unit using RS-232 to a PC, use the cable as shown:
Note:
Jumper pins 4-6 and 7-8 at the DB-9.
Port 2: RS-232 Terminal Block
Rack or Panel Mount
The terminal blocks of the Rack and Panel units use pins 37 to 44 for RS-
232 port 2.
You can use terminal block 46 for the cable shield; however, block 47 and
48 are the power supply so use caution.
