It does this by cycling the drive motors periodically between runs of 3600 RPM (or 3000 RPM for a 50 Hz system) normal operation and a few seconds of a high frequency 4500 RPM (or 3900 RPM) cleaning mode operation. It is important to understand that it is not the high frequency itself that causes the cleaning, but the sudden transition from the normal operating frequency to the higher frequency and back that disrupts the pattern of the vibration modes established in the wire cloth. The high frequency serves to lift the material off of the screen for a few seconds before reestablishing material flow. As long as the material is being bounced above the screen, the screen is unable to filter material. The high frequency cleaning mode can also damage the wire cloth and other components of the screen machine. Therefore, the amount of time that the screen is in the high frequency cleaning mode should never exceed fifteen seconds at a time and should be for the shortest length of time that will allow for the complete transition from the normal run frequency to the cleaning frequency and back. If extra cleaning is required, this can be achieved by reducing the duration of the normal operation run, thereby increasing the average number of the cleanings per hour.This manual will instruct you on how to initially install and set up your J&H Speed Clean system. Following this will be instructions on adjusting the time intervals and frequencies of the J&H Speed Clean to optimize its performance for your particular application. Please read the entire instruction manual carefully.WARNING: The J&H Speed Clean AC Drive Controller uses capacitors to store a charge. Dangerous voltage may exist even after disconnecting the power source. Wait (5) five minutes after disconnecting power supply before proceeding with any electrical work.J&H EQUIPMENT INC.SECTION IIINSTALLATIONOne speed clean is required per screening machine. The J&H Electronic “Speed Clean” is an AC Drive controller that is installed in the high voltage side of the power feed to the screening machine drive motors. The input voltage must not be allowed to fluctuate more than 15% above or below the rated voltage. Voltage above or below the limits will cause the drive to trip with either an overvoltage or undervoltage fault. Fuses and a disconnect switch must be provided according to local electrical code requirements.The J&H Speed Clean control box should be located so that the motor lead cable is no more than fifty (50) feet long. If a longer lead cable is required, the J&H Speed Clean may need to be installed with shielded cables and noise filters. The J&H Speed Clean AC Drive enclosures exceed NEMA 1, 12 and 4X standards.The frame dimensions for the AC Drive Controller is 12.01” (306mm) in height x 8.72” (221 mm) in width, 6.51” (166 mm) in depth, and weighs 14.0 lbs (6.4 kg). Do not install the controller directly onto the screen machines (maximum vibration limits are 1 g @ 57-150 Hz). Do not install the box where it will be exposed to direct heat-radiating elements or in direct sunlight. Allow room for ventilation and heat dissipation. Control box must be installed vertically. Install the control box where the front side of the control box can be easily accessed for installation and setup programming.(4) Four ½” x 3” bolts (or equivalent) should be used to mount the J&H Speed Clean AC Drive box. Four 2” rubber buffers should be used to isolate the control boxes from environmental vibration. The bolt hole pattern is spaced 11.03” (280 mm) vertically and 7.88” (200 mm) horizontally.Remove the four cover screws that secure the front cover of the J&H Speed Clean box. The terminal strip is located at the bottom of the enclosure. Connect the power ground wire to the left ground terminal (GND) of the terminal strip. Connect the three phase power input cable to terminal connections L1/R, L2/S, L3/T. Verify proper line connections according to local wiring conventions for 3-phase service. (See diagram 1).J&H EQUIPMENT INC.Connect the J&H 3600 Drive Motor lead wires to connections T1/U, T2/V, T3/W, and GND. The lead wires must go through a manual starter switch (as shown in diagram 1). The J&H 3600 Drive Motors are 1.5 HP, 3 phase, 9 lead Y-load, 285/575 Volts, 3.6/1.8 Amps, 60 Hz, 3450 RPM, TENV Induction motors. Verify that lead wires are connected to the correct motor terminals T1, T2, and T3.J&H EQUIPMENT INC.If the J&H Speed Clean unit will be operated remotely from a control room or from a DCS control system, then a control cable will need to be connected to the control terminal strip. This is located on the left side of the upper deck and is labeled with the terminals FWD, REV, R/J, DI1, DI2, DI3, DI4, DI5, MOL, and +24V. Use an AWG 14 (1.628 mm diameter) shielded control wire or equivalent, with a 9/32” (7mm) stripped end. Connect the positively energized 24VDC lead of your cable to the terminal +24V on the Speed Clean unit. The other wire of the cable should be connected to the FWD terminal. As long as the control circuit loop is energized with 24 VDC with a source capacity of 150 mA, the sequence programmed into the drive unit will run. Replace front cover and secure with the four cover screws.J&H EQUIPMENT INC.J&H EQUIPMENT INC.J&H EQUIPMENT INC.Program Mode: Allows operating parameters and programmed sequences to be input or changed. There are three different levels of the program mode, Level 1, Level 2, and Macro mode. Level 1 is accessed by pressing the PROG input key and gives access to some of the most common operating parameters. Level 2 is accessed by pressing the SHIFT and PROG input keys and provides access to all parameters. Macro mode is accessed by holding the PROG input key for more than 3 seconds and provides access to the most common parameters of the Level 1 group as well as special parameters for activating macro operations, program sequencers, or serial communication. In the instructions below, the parameter number and description will be followed by either [MACRO], [L1], or [L2] to indicate which program mode you are in for each of these commands.In the text of this manual, following a parameter will appear a program mode code [macro], [L1], or [L2] to remind us which programming mode that that particular parameter resides in as described above. This is not anything that you will see on the actual J&H Speed Clean unit screen. As this manual is written to be a step-by-step sequential set of instructions for completely programming the J&H Speed Clean, the program mode instruction may not be directly associated the parameter in this text. The program mode code will be useful if you need to refer back to this manual to adjust a single parameter value. Simply note the program mode code and follow the instructions given in the paragraph above to get to the correct program mode and find the parameter in question. Note that in this text, other than the couple of [macro] level codes at the beginning, you will accessing most of the codes through the Programming Mode Level 2. This is simply so that all codes can be accessed without having to change programming mode levels. However, for the purpose of single parameter access, if a code can simply be accessed at level 1, it will be designated as an [L1] parameter and not [L2]. The parameters that are indicated with the [macro] or [L2] can only be accessed from those levels.Fault Mode: Displays error messages, and may provide corrective active advice. If a fault occurs, the red LED on the STOP input key will flash and one of thirty-three (33) Fault Messages will be displayed. Pressing the SHIFT input key will display an Advanced Fault Code (a number from 0 to 5) that will provide additional information concerning the fault. Pressing the UP or DOWN arrows will cycle through the Drives Status, Fault History, and Last Fault. Contact J&H equipment for support for a particular fault message or for troubleshooting a fault.J&H EQUIPMENT INC.J&H EQUIPMENT INC.J&H EQUIPMENT INC.P201 is the default initial parameter for Level 2 programming. If you do not see this parameter, scroll through the parameter selections using the UP and DOWN arrows until 201 Input Mode[L1] is visible in the display window. Although there are several values that this parameter can be set to for different access applications, for the operation of the screens, this parameter should be set for one of two values: “Local Only” or “Remote Only”. The “Local Only” will be used if the screens are not connected to a control room, but are operated locally from the machines, or for setting up the Speed Clean drive system during initial programming and installation test. Otherwise, if you have connected a 24Vdc control cable to the unit per the instruction in the Installation Section above, then this parameter should be set for “Remote Only”, so that it can be operated only from the control room. We will return to this parameter later to determine the final setting, however, for the initial programming of the Speed Clean drive, this parameter must be set to “Local Only”. If this value does not appear, press the SHIFT input key and use the UP and DOWN arrows to correct this value. Press ENTER to accept.IMPORTANT - Check the nameplate on the motors that will be driven by the J&H Speed Clean. The standard motor rating for J&H motors for most locations is 575 Volts / 60 Hz. The motor rating will determine the values that you should input for the next five parameters. Inputting the incorrect value could damage your system or cause it to operate inefficiently.Parameter 503 V/Hz Knee Freq[L2] is used to program into the AC Drive control logic the frequency at full line voltage. The default setting is 60 Hz. If your drive motors are rated for 60 Hz, you may continue on to the next instructions. If your voltage supply is at a different frequency, this value will need to be changed to the value listed on the motor nameplate. For example, if you are at a location that uses a 50 Hz frequency, then 503 will need to be changed from 60 to 50. Hit ENTER to input the new value. Parameter 509 Rated Mtr Volt[L2, macro] is used to program into the AC Drive control logic the full line voltage for your system. The program uses the 503 and 509 parameters to determine the Voltage versus Frequency curve in the program logic. The default setting is 460 Volts for this AC Drive model. The JHV3600 Vibrator motor is rated for 285/575 Volts at 60 Hz for Low voltage and High voltage terminal connections respectively. This value will need to be changed to the 575 V high voltage value listed on the motor nameplate for most applications. For 50 Hz locations that use 380 Volts, then 509 will need to be changed from 460 to 380. Hit ENTER to change this value.Next, use the DOWN arrow to go to parameter 302 Max Frequency [L2]. The default value for this parameter is 60 Hz, which must be changed to an appropriate frequency for your application. The value that should be input into this parameter depends on the value of parameter 503 set above (See the 503V/Hz Knee Freq instructions above). If the motor frequency rating is 60 Hz, then use the SHIFT input key and then the UP arrow to change this value to 75.1 Hz. However, if your motors are rated for 50 Hz, then you should set this parameter for 65.1 Hz. You may press the button once to advance by 0.1 Hz, or you may hold the key down to continuously advance with increasing step size. Press ENTER.Scroll up to 306 Preset Freq 4 [L2]. The default value for this parameter is 30 Hz, which must be changed according to the motor rated frequency. Use the SHIFT input key and then the UP arrow to change this value to 60 Hz or 50 Hz depending on your motor. Press ENTER. This will be the normal run frequency for the J&H 3600 Vibration motors.J&H EQUIPMENT INC.Press the UP arrow once to go to 307 Preset Freq 5 [L2]. The default value for 307 is 40 Hz. Use the SHIFT input key and then the UP arrow to change this value to 75 Hz for a 60 Hz rated motor, or 65 Hz for a 50 Hz rated motor (see 503 above). Press ENTER. This will be the target cleaning frequency for the J&H 3600 Vibration motors.Use the arrows to go to 402 Accel Time 1 [L1]. Hit SHIFT and the DOWN arrow to change the value from the 5 seconds default down to 3 seconds. Hit ENTER. Then repeat with 403 Decel Time 1 [L1], changing from 5 to 3 seconds. Press ENTER. These two commands tell the AC Driver how fast to change from the normal run preset frequency (at 306) to the cleaning preset frequency (at 307). Three seconds is based on the 15 Hz frequency change at 1 sec per 5 Hz frequency change.If the J&H Speed Clean unit will be operating in an environment in which the surrounding air temperature will drop below –7 degrees C (below 20 degrees F), then an arctic mode must be set. Use the UP arrows to go to 410 DB Config [L2]. The default value is DB Internal. Hit the SHIFT key and then use the arrow keys to change the parameter to Int-ARCTIC. When DB Config is configured to “Int-ARCTIC”, dynamic braking becomes active if the drive temperature drops below –7 degrees C. When DB becomes active, an “ARCTIC Mode” warning flashes on the keypad. If the drive drops below –10 degrees C (14 degrees F), the drive will be disabled and not allowed to run. The keypad will indicate a “Not enabled” state at this point. If the drive heats up after being below –10 degrees C, the drive must meet the following criteria before operating again: a) Drive temperature must be above –9 degrees C, and b) Drive temperature must stay above –9 degrees C until a time period has elapsed. The time period is dependent on how far below –10 degrees C the drive was. Each degree below –10 degrees C adds another 4 minutes before restart.J&H EQUIPMENT INC.J&H EQUIPMENT INC.J&H EQUIPMENT INC.J&H EQUIPMENT INC.SECTION VOPTIMIZATIONThere are three adjustments that can be made to optimize the J&H Speed. The first is the duration of the cleaning phase of the Speed Clean operation. Press SHIFT and FWD to run the motors continuously. Listen to the motors during the high frequency phase of the cycle. You should be able to hear a ramp up, a second or two of steady operation at the higher frequency, and then a ramp down to the normal frequency value. It may be necessary to increase the duration of this sequence by a couple of seconds to make the most use of transition disruption caused by the frequency changes. The plateau duration of the clean phase should not be more than three seconds and the overall duration of the cleaning sequence should never exceed fifteen seconds. To change this parameter, adjust 952 – Seq Count 2 up or down in one second increments. The other two adjustments can only be performed after observation of the screens in actual operation in material load conditions.The J&H Speed Clean should maintain the wire cloth relatively clean with about 10% of the cloth blocked by material. If you do not see some blockage of the wire cloth, then this might indicate that the product material is not making as good of contact with the wire cloth as it should be. First check to make sure that the product flow velocity and distribution are good. If less than 10% of the screen is blocked by product from the preceding normal operation run, then the J&H Speed Clean is going into clean mode too often, and the length of the normal running time should be increased. Make this adjustment by increasing the time at 951 – Seq Count 1 by increments of 60 seconds, for instance by changing the value from 900 seconds to 960 seconds. Continue to monitor the screens and adjust the duration of the normal run until you are satisfied that the wire cloth is being maintained at a good level of cleanliness while minimizing the occurrences of the Cleaning Modes.If the wire cloth is accumulating product material, increase the amount of cleaning from the J&H Speed Clean by reducing the duration of the normal operation time. Make this adjustment by decreasing the time at 951 – Seq Count 1 by increments of 60 seconds, for instance by changing the value from 900 seconds to 840 seconds. Increasing the occurrences of the cleaning mode will reduce the efficiency of the screen, therefore you should only decrease the normal run time to provide adequate cleaning. 10% blockage of the wire cloth is considered normal and is a good sign that the screen is operating properly. It may be necessary to repeat the optimization procedure each time that the plant process is changed.If you have reduced the normal operation run to 600 seconds and the material is still accumulating onto the wire cloth, then there may be a more serious problem with the production process. The material may be gluing itself to the wire cloth rather than just getting stuck in the openings, and no reasonable amount of amplitude or shaking frequency will clean it. Contact the Process Designers immediately if you think that this condition exists. Adverse product composition can be disastrous to the life of the wire cloth and the screen machines.J&H EQUIPMENT INC.SECTION VIFAULTS & MAINTENANCEFAULTSThe J&H Speed Clean has the ability to monitor itself for a wide range of problems and parameter faults. If the Speed Clean encounters a problem, the red LED on the STOP input key will flash and a fault message will appear on the display. Write down the Fault Display. Press the SHIFT input key and use the UP and DOWN arrows to cycle through the Fault History, Advance Fault Code, and Status records. Write down all information provided by these records. Sometimes, the J&H Speed Clean will suggest an action to correct the fault. Press SHIFT again to return to the programming mode fault parameter. Contact an engineer at J&H Equipment at (770) 992-1606 or at jhsys@ to get more information or further instructions on handling this particular fault.MAINTENANCEOnce properly set up, the J&H Speed clean is virtually maintenance free. It is recommended to periodically wipe the box with a damp cloth. A mild soap or bleach solution may be used but it is not recommended to use any abrasive cleansers. Care should be taken when wiping the touch pad and display window area to not scratch the surfaces.A month or two after the initial installation, it is recommended to power down the J&H Speed Clean AC drive, open up the enclosure and retighten all of the electrical connections. Then once a year, the connections should again be checked for tightness and inspected for any corrosion. Check the motor lead cables for signs of damage to the insulation or any wearing of the insulation, particularly where the cable is in contact with vibrating equipment. Replace cables if damage or significant wear is observed.Thank you so much for your purchase of the J&H Speed Clean system. By carefully reading these instructions, properly setting up your application, and contacting J&H Equipment for support and new products, your J&H Speed Clean should provide many years of improved J&H Screen performance and life and reduced plant maintenance.。
