HARVEST TEC 474C Hay Indicator Kit Owner’s Manual

HARVEST TEC 474C Hay Indicator Kit

Caution: Unhook the pump leads when testing, aligning or working around the hay indicator sensors or nozzles. The nozzles will spray if someone or something comes in front of the sensors when the applicator is turned on. Failure to do so may cause injury.

Overview

The hay indicator kit is designed to automatically pause the applicator when no hay is entering into the machine. The hay indicator kit will turn the applicator back on when hay starts entering into the machine. Two photoelectric sensors will mount to the baler’s pick-up head, one on each side, to sense whether hay is entering the machine. The hay indicator kits are designed to work with all Harvest Tec Models. The following table shows what hay indicator kit is needed for each applicator:

TOOLS NEEDED

• Standard wrench set
• Standard socket set
• Standard screwdriver: Blade and Phillips ends
• Side cutter
• Hole Saw (1-1/4″)

Mounting Instructions for Hay Indicator on the Baler

Important: Keep in mind the following things when selecting a location to mount the hay indicator. One sensor must be mounted on each side of the pick- up head, so that they are lined up directly across from each other, as well as pointing directly toward one another. Also, the sensors should be kept clear of all obstructions when moving the pickup head up or down. The obstructions could be in one or more of the following forms:

1. The wind guard could block the sensor’s beam when the pickup head is moved up or down.
2. If the sensors are located too near to the preservative nozzles, drift can travel from the nozzles and hit the sensors. The drift will attract residue and falsely trip the eyes.
3. When positioning the sensors, consider where the hay could have a tendency to wrap up on the sides of the head.
4. Teeth on the pick-up will NOT normally trip the sensors. However, if the teeth become out of alignment, they could be staggered enough to cause the hay indicator to trip. If possible mount the eyes in front, above, or behind the teeth, it will eliminate the problems from bent pick-up teeth.

The hay indicator mounting bracket can be used in different combinations to match up to your specific baler. The best mounting locations will use either existing bolt heads on opposite sides of the chamber or holes drilled through the baler’s sheet metal facing each other. Make sure the sensor’s locations are properly aligned, by using a long straight edge that spans the width of the head, such as a PVC pipe. Position the long straight edge so that it is perpendicular to the surface being used to mount the sensors as well as the level to the horizontal (or a flat floor). Use a level to serve as a gauge.

Alignment of the sensors

The hay indicators have a built-in alignment scale on one of the sensors. When the sensors have power to them the letter A will light up and one of the corresponding numbers will also have a light on next to it. The higher the number that is lit the better the alignment is between the two sensors. The sensors will need to be adjusted until the number 3 light is showing. Aligning to level 4 is not necessary for the application system. Once this alignment is made tighten down all hardware to prevent movement of the sensor.

Installation of Sensor to Mounting Bracket

The three most common mounting points for the hay indicator are shown above. Take note of the differences for mounting on your specific baler.

Option 1

Use the two mounting screws supplied with the sensors to attach the sensor and bracket together. This mount will require a hole to be drilled in the sheet metal for the sensor to see through, and one or two holes to be drilled (depending on the baler) for the bracket to attach to the baler. Install the trash plate between the eye and the baler sheet metal to prevent chaff from building around the eye (only on balers when a 1-1/4″ hole must be drilled).

Option 2 & 3

Connect the sensor to the baler using the 2 plastic nuts supplied in the kit. The amount will require one or two holes to be drilled (depending on the baler) for the bracket to attach to the baler.
