Specifications

Touch Screen Operator Interface and include a run light, HOA switch and speed pot. In manual mode, the

user can manually adjust pump speed.

A Clear PVC calibration tube shall be included on the injection pump suction to accurately calibrate the

metering pump over a minimum 30-second test.

Chemical Storage Tank Level Transducer: If called out for in the specifications, a fluid separated level

transducer shall be provided to monitor chemical storage tank level of each tank. The transducers will be

wired to and scaled by the same PLC, which controls that irrigation pump station. The level will be

displayed in inches of tank level on the pump station operator interface devise. If supplied as part of the

specification the level will also be displayed through the pump manufacturer’s remote monitoring and

control software on customers PC. Tank information can be monitored in inches or if configured, volume

in gallons. From either location, at the pump station or remotely, an alarm setpoint can be configured for a

low chemical level shutdown of the injection pump. This alarm will be logged at the pump station and at

the remote PC. The alarm will notify the user by email notification or using a dial up pager.

Controller Hardware Specifications:

Full battery backed memory for program storage, product configuration information and control

parameters.

RS232 port available for MODBUS™ communication over modem, wireless or wired connections.

Real Time Clock/Calendar.

Hardware for monitoring of water flow meter rate.

Analog inputs available upon request for chemical tank level monitoring

Controller Functional Capabilities:

System shall be capable of injecting each product proportional to the irrigation pump station flow rate.

All injection programs and applicable parameters must be accessible through the pump station Operator

Interface Device and through pump manufacturers remote monitoring and control software.

At the pump station the user shall have the ability through the color Touch Screen Operator Interface

device and remotely through monitoring software controls the ability to set QTY (3) unique separate

lockout periods per day. Also, the remote monitoring software shall have the functionality to automatically

email a report notification, audible alarm indication and having the ability to change each metering pumps

injection rate proportional to station flow without having to do so manually at each pump.

The fertigation software controls shall have the ability to monitor and display the chemical tank levels and

to shut down the injection pumps on a low tank level. The injection system shall provide the ability to

setup the chemical storage tank diameter and display the tank level in gallons when a level transducer is

supplied by the pump manufacturer.

Hoses and fittings per pump:

15 feet of ½” diameter discharge hose rated to 250 pounds working pressure

15 feet electrical conduit

15 feet motor cable

PVC check valve

PVC isolation valve

PVC injection quill

PVC suction and discharge plumbing at each head

Fiberglass mounting base

Installation /Start-up:

It is the responsibility of the customer to provide any necessary pad or containment for tanks prior to

installer arrival. It is the responsibility of the customer to provide the chemical supply tanks and connect

from tanks to suction connection of each injection pump. Installation to include complete assembly and

water testing of system & operator training
