When programming the hydrapulse unit, please make sure not to skip any of the steps. The conveyor must be running at all times when programming the switch with no cars in the tunnel.
Before you start programming the hydrapulse unit, please make sure the hoses are connected correctly onto the ports. See diagram below:
Follow the steps below to properly calibrate your ACE84 hydrapulse unit. If you need any further assistance please contact your Sonny's technical support team.
1. Place two marks 200 inches apart on the conveyor. These marks will be used to time a conveyor roller.
2. Remove the cover from the Hydrapulse Switch enclosure and locate the three buttons shown in Figure 3.
3. Turn on the conveyor. After a few seconds the display will stabilize. Once calibrated the display will show an average speed for the last 2 seconds. The Hydrapulse Switch can display your conveyor speed in two formats: ‘feet per minute’ or ‘cars per hour’ (a standard car length and space is 21 feet). To select ‘feet per minute’ press and release button 1. For ‘cars per hour’ press and release button 2.
All calibration values are in ‘feet per minute’. Once the unit has been calibrated to match your conveyor the display format can be selected as shown above.
NOTE: The conveyor must be running and brought up to a high constant speed throughout the entire calibration process. To get the best readings the flow control speed should be set around 6-7. Cars should not be on the conveyor during the calibration process.
4. Press and release button 1. This sets the display to ‘feet per minute’.
5. Using your stopwatch, measure the time in seconds that it takes a roller to go from your first mark, to your second mark.
6. Calculate your conveyor speed using the formula: 1,000 divided by the time recorded in step 5.
NOTE: For accurate results use speed values between 40 and 90 ‘feet per minute’. If value is less than 40 or greater than 90, use flow control to adjust conveyor speed, repeat steps 5 & 6.
7. Press and release button 3. The left digit on the display will begin to flash. Use buttons 1 and 2 to adjust the display to match the value calculated in step 6, noting the decimal place. Button 1 increases the display while button 2 decreases it. If buttons 1 and 2 are held down, the display will change quickly.
8. Once the display matches the calculated value press and release button 3. The displaywill now go blank for 15 seconds. After 15 seconds the display will now read “2.0” and the middle digit will now be flashing. Using buttons 1 and 2, adjust the display to set the number of pulses you wish the Hydrapulse Switch to generate per foot of conveyor movement.
For example: If you want your pulses to be 6 inches apart, leave the display at “2.0”. For 8 inches apart, adjust the display to “1.50”.If you are trying to match an existing pulse rate you can calculate that by dividing a function’s pulse count by the distance to the enter switch. Use functions at the end of the tunnel to be most accurate.For example: If the air dryer was previously set at 100 pulses and is at a distance of 60 feet, the pulse rate is 100/60 or 1.67 pulses per foot. The formula for calculating this number is 12/(the number of inches for each pulse).
NOTE: For customers with DRB Controllers – DRB’s tunnel controllers prefer to have one pulse per sprocket revolution. This means that if you have a standard 12-tooth sprocket,then your pulses per foot rate should be 0.37(12”/31.92” per sprocket revolution=0.37) When using a 4 tooth sprocket then your pulses per foot rate should be 0.45(12”/26.69”per sprocket revolution=0.45)
9. After the pulse rate has been set, press and release button 3. After a few seconds the display should now show the speed of the conveyor. If the value is incorrect, repeat steps 1 to 6.
10. You can now select the display format. For display in ‘feet per minute’ press button 1. For‘cars per hour’ press button 2.
11.Replace cover. the Hydrapulse Unit is now calibrated to match your conveyor. The values recorded are retained even if the power is removed.
