Mounting Holes: dia. 0.201”

n = number of pump heads

Installation Instructions

Mount the pump on a vertical wall surface using the holes in the mounting flanges. The center flanges hole may be used to hang and level the pump, however, the corner screw holes should be used for flanges mounting. Use caution to avoid over-tightening the screws and bending the flanges.

A 120Vac wall receptacle is required within 6ft of the pump for the power adapter.

Do NOT connect the Grow NET port to Ethernet networks.

Connecting Pump Tubing

Each pump has an inlet (suction) and outlet (pressure) tube. Using included barbed tubing connectors, install an inlet tube for each pump into the respective concentrate container, then install an outlet tube to the mixing reservoir or injection manifold.

Shown with optional PBX-100 series injection manifold designed for easy installation with a re-circulating pump for continuous recycling.

Connection to Grow Control™ GCX

All Grow NET™ devices are connected using standard CAT5 Ethernet cable with RJ-45 connections.

Devices can be connected directly to the Grow NET™ ports on the bottom of the controller, or through HX8 Grow NET™ hubs. It is typical to simplify cabling by locating hubs centrally in hall ways and rooms allowing single runs from an 8-port device hub back to a central hub or back to the controller.

Refer to the GCX controller manual for details on adding the device to the system.

Grow NET™ Hubs

HX8 Grow NET ™ hubs expand a single port into eight more ports. Hubs can be daisy-chained to form a network of up to 100 devices per Grow NET™ bus. Individually buered port transceivers provide excellent signal integrity and extended communication strength and range.

Hubs provide up to 1A of power for operating sensors and most relays directly over the CAT5 cable. A DC jack on the hub provides 24Vdc power to the ports from the included wall power supply. A terminal block power option is also available.

Installation Notes

NOTICE
Grow NET™ ports use standard RJ-45 connections but are NOT compatible the Ethernet network equipment. Do not connect Grow NET™ ports to Ethernet ports or network switch gear

DIELECTRIC GREASE
Dielectric grease is recommended on RJ-45 Grow NET™ connections when used in humid environments. Place a small amount of grease onto the RJ-45 plug contacts before inserting into the Grow NET™ port. Non-conductive grease is designed to prevent corrosion from moisture in electrical connectors.

• Loctite LB 8423
• Dupont Molykote 4/5
• CRC 05105 Di-Electric Grease
• Super Lube 91016 Silicone Dielectric Grease
• Other Silicone or Lithium based insulating grease

Connection to SXHM Controller

Connect an ADi dosing pump directly to Agrowtek’s SXHM hydroponics sensor to form a powerful,  autonomous pH and EC set-point dosing system. Operate a single, dual or quad AgrowDose pump and congure each pump as an EC part or pH up or down part. Automatically maintains pH and EC concentrations with a simple repeating recipie dosing method.

A direct-link connection between a SXHM sensor and ADi pump requires Agrowtek’s cross-over adapter.

IMPORTANT! ONLY use cross-over adapters provided by Agrowtek’s. Do not use other cross-over adapters or cross-over cables unless they are constructed exactly as diagramed on the cross-over diagram. Incorrect cross-over adapters or cables can cause damage to the equipment.

Please see the “MDX” product manual for more information on setting up and installing the MDX mini dosing system.

MDX System Instruction Manual

Cross-Over Cable

A custom cross-over cable can be constructed as an alternative to using the cross-over adapter and two standard, straight Ethernet cables as shown in the diagram above. The cross-over wiring MUST match the diagram below.

Pins 7 & 8 carry 24Vdc power and must be straight through or damage may result to the equipment.

Connection to USB Agrow LINK

LX1 USB Agrow LINK connects Agrowtek’s devices to a computer’s USB port for:

• Firmware Updates
• Conjuration
• Batch Dosing Control
• More

1. Download the installer from Agrowtek’s website.
2. Open the installer and follow the command prompts.
3. If you are given a security warning asking permission to modify les (install them,) select YES.

Connect the USB Agrow LINK and allow the drivers to automatically install. Wait until a message is displayed in the task bar in dicatin the device is ready to use (it may take several minutes.) If the device drivers fail to install, you can install them from the Batch Master software.

Driver Installation
If the device drivers have not automatically installed:

1. Open the Batch Master program.
2. Ignore warnings that advise the Agrow LINK was not detected (press OK.)
3. From the top menu bar select: USB AgrowLINK > Install Driver.
4. The driver installer will open; follow the command prompts to complete the driver installation.

Detect the Agrow LINK
If your Agrow LINK was not connected before you opened the program, you can search for it by selecting: USB Agrow LINK > Detect Agrow LINK.

Running a Recipe

Each pump may have a setting for the dose volume (mL) and the ow rate of the pump (mL/min).

To create a batch recipe:

1. Set the ow rate for each pump. Most applications will use the pumps at full speed. The speed may be reduced if required for your application.
2. Set the volume that each pump should dose.
3. Save the recipe if desired by selecting: File > Save. Choose a location and name the le then press “Save.”

Saved recipies may be recalled by selecting: File > Open and choosing a recipe file.

Run a Batch
Once the recipe is congured, it may be “run” by pressing the green “play” button. The pumps will begin dosing with the rst pump. Once the specied volume is completed, the next pump will begin. When all pumps have metered the volume in the recipe, the batch is complete.

Stop Pumps
All pumps may be stopped immediately by pressing the red “stop” button.

Prime
Each pump may be primed for 10 seconds automatically by pressing the “Prime” button for the respective pump. The pump will operate at the speed selected allowing the speed to be previewed or tested.

Connection to MODBUS RTU

RS-485 / RS-422
Use the LX2 Mod LINK to connect MODBUS devices to the Grow NET™ port

3.3/5Vdc Serial Bus Compatible.
Include required bus terminating resistors per EIA standard.

Serial Speed & Format

The default serial data format for the LX2 Mod LINK interface is: 19,200 baud, 8-N-1.

Alternate speeds and formats between 9,600 – 115,200 baud may be congured with the free Agrow LINK PC utility using a LX1 USB Agrow LINK and the cross-over adapter supplied with the LX2 Mod LINK.

Supported Commands

• 0x03 Read Multiple Registers
• 0x06 Write Single Register
• 0x16 Write Multiple Registers (for motor speeds only)

A request to use a function that is not available will return an illegal function exception.

Register Types

All registers are 16 bits wide with addresses using the standard MODICON protocol. Floating point values use the standard IEEE 32-bit format occupying two contiguous 16 bit registers. ASCII values are stored with two characters (bytes) per register in hexadecimal format.

Motor Operation Registers

Motor Speed
Motors are operated simply by sending the desired speed to each motor’s speed register. Positive percentages result in CW (forward) rotation while negative percentages result in CCW (reverse) rotation.

FORWARD: +60 to +100% | REVERSE: -60 to -100% | STOP: 0%

Speeds below 60% may result in a stalled motor and should not be used.

Included power supply is sucient to drive a single motor at a time.
Driving multiple motors simultaneously may cause the power supply voltage to drop below acceptable levels and put the pump into a fault protection mode requiring a power cycle. To drive multiple motors reliably, provide 0.5A/Motor (2.1mm jack, center positive)

Motor Life
Motor life and service intervals can be tracked by observing the pump motors’ accumulated run time which is tracked in seconds in a 32-bit unsigned integer register for each pump motor.

Timeout
Timeout value (seconds) can be set to shut o all pumps in the even no communication is receieved from the master device within a set period of time.

Maintenance

Agrow Dose pumps are low maintenance and have a durable DC motor and non-servi cable gear box for very long life. Pump tubing is non-servi cable and the economical pump heads are replaced as units with new rollers, tubing and lubricant. Head replacement does not require any tools and takes only moments.

Replacing Pump Head

Pump heads are replaceable when the tubing wears out from extended use. Pump heads typically last 12-24 months depending on the volumes being dispensed and frequency of use. When the tubing begins to leak, replacement is a simple process:

1. Rotate the pump head counter-clockwise 1/8 turn
2. Slide the head off of the motor shaft.
   

Replace in reverse order.
