ONGRATULATIONS Congratulations on your purchase of an Amity Technology Air Cart! Your Model 5250 Air Cart has been designed to be durable, versatile, and simple to use. Your Air Cart features stainless steel tanks and metering components, a streamlined and reliable meter system, a fi ll/ unload auger with cupped poly fl...
ECHANICAL YSTEMS ETUP AND PERATION Safety Railing / Ladder Your Air Cart is equipped with a ladder and safety railings for access to the top of the tanks. Always make sure that the safety railings are secured in the raised position when operating the air cart.
Auger Your Air Cart is equipped with an auger for loading and unloading the product bins. The auger is mounted on a swing arm that al- lows a fl exible discharge hose to be moved to each compartment without moving the hopper. The swing arm also enables the auger to be turned around to unload and clean out the compart- ments.
Using the Auger to Unload Products 1. Swing the inner arm far enough away from the machine to allow the hopper to fi t in front of the wheels. See diagram for inner arm position. 2. Place the hopper under the meter for the compartment you wish to empty.
Hydraulic Systems The hydraulic system on 5250 air carts consists of a blower con- trol circuit, an auger control circuit, and a hydraulic meter drive control circuit. A combination of various control valves enables all three circuits to be powered by one hydraulic remote on the tractor.
Air Cart to Tractor Hydraulic Couplers (tow between cart) The couplers connecting the air cart to the tractor are (1/2”) #10 ISO 5675 (Pioneer) tip couplers connect the blower pressure and return lines to the tractor. A (3/8”) #8 ISO 16028 (fl at-face) coupler tip on the drill connects the case drain line to the tractor.
The hydraulic drive motors mount to the meter housing and provide a direct drive of the meter shaft. The motor has a built-in speed sensor to provide accurate meter speed feedback to the electronics system. Hydraulic drive Meter Drive Motor Blower The air cart's blower system generates air pressure/fl...
Setting Blower Speed The blower should be operated at as slow a speed as possible to prevent damage to seed. If operated too slowly, line blockage will occur. Typical blower speeds are between 3000 and 6000 RPM. Drill width, product, rate, humidity and other factors affect blower speed.
D3 S YSTEM VERVIEW Your Air Cart utilizes a state-of-the-art electronic system to moni- tor and control the air cart's functions. The D3 ISO Monitor sys- tem is based on the ISO 11783 standard, often also referred to as ISOBUS. ISOBUS is a communications standard that enables a variety of agricultural electronics systems to talk to each other.
Blower Speed Sensor An inductive sensor on the blower fan provides speed informa- tion to the ECU. Bin Level Sensor Optical bin sensors indicate when the level of product in the bin has decreased to the level of the sensor. The same sensor detects all types of products.

Selecting Air Stream (Dual Chute Only) In dual chute equipped systems; one can switch air streams for any desired product combination. To switch air streams: 1.Remove wing nuts from baffl e slide & plug 2.Remove slide and direct into the air stream desired 3.Replace plug and wing nuts Note Do not use wrench to tighten wing nuts.
Adjusting Product Meters The product meters deliver seed or fertilizer from the product bins to the air stream via a fl uted roller. The amount of the roller that is being used determines the rate at which products are ap- plied.

Hydraulic Drive Calibration and Operation Calibration is done in four parts. First, you must prepare the system for calibration. Second, you prime the meter. Third, you take a sample and weigh it. Finally, you enter the sample, or Accumulated weight into the virtual terminal. Preparing to Calibrate the Meter Hydraulic power is needed for calibration.
Page 21
Priming the Meter To ensure accurate calibration, the meter must be primed with product. 1. On the ECU keypad, locate the button with the number cor- responding to the meter you are calibrating. This is called the ECU Calibration button. 2.

Entering Accumulated Weight on the VT 1. On the Home page, press the soft key for the desired bin. The Product page for the selected bin appears 2. On the Product page, select Accum (lbs). 3. Enter the accumulated weight value obtained in the meter calibration procedure in pounds.

Changing Metering Rolls - Hydraulic drive System To change metering rolls on a VR System: 1. Close the meter gate or ensure the bin is empty. 2. Remove the meter door and set aside. 3. Remove the (2) ½” bolts holding the hydraulic motor to the motor mount.

Other Meter Adjustments The following adjustments are done at the factory and should only be done by a trained service technician. Shims • The meter roll should have a small gap (.030”) between the roll and the meter housing for proper operation. If the gap is too large product can leak around the meter roll into the air stream.

Storage • Fully open the seed meters. • Open clean out doors on the bottom of the air tube. • Clean any remaining product from tanks. • Use water to thoroughly clean any compart- ment used for fertilizer • Thoroughly clean fertilizer and dirt from cup area.
