SHOWVEN HC8600 Type Sparkular Waver Fall

Showven Technologies Co., Ltd.

Thanks for choosing SPARKULAR® waver FALL, we wish it will sparks up your show.
Please read the following manual carefully before operating this product.

Safety Instructions

\ Unauthorized repair are prohibited, it may cause serious incident.
\ SPARKULAR® waver FALL can be used in rain, please keep the device dry after use.
\ Make sure lid of feeding hopper are well covered when use SPARKULAR® waver FALL.
\ Consumable should keep away from moisture and stored in a dry sealed environment.
\ Check whether there is consumable aggregate in the output nozzle both before and after each show, if any, please clean it up, or it will affect the firing effect, damage machine, even cause serious incident.
\ There will be some sparks drop to ground, make sure there are no flammable objects such as
carpet on the ground within the safety radius of the machine.
\ The SPARKULAR® waver FALL power supply cable maximum allowed cascade of 6pcs (220V version) / 3pcs (110V version), exceed connecting may result in damage or even cause fire.
\ Cover the output nozzle of SPARKULAR® waver FALL is forbidden, inspect the machine before each show, making sure no objects or material will block the output nozzle.
\ Never touch the nozzle of SPARKULAR® waver FALL danger of getting burnt.
\ Never touch the sparks which shooting out from the nozzle.
\ Make sure no staff, audience and flammable materials stays under the SPARKULAR® waver FALL.
\ Safety Distance
\ Safety distance for SPARKULAR® waver FALL divided into two parts safety radius around machine (a) and safety distance at firing direction (b). No person and flammable materials are allowed to stay inside the safety isolation zone when SPARKULAR® waver FALL was armed.
\ The safety radius around machine of 1.5m.
\ For safety distance at firing direction equals to maximum firing height + 1m. SPARKULAR® waver FALL with maximum ±90° waving firing angles, when firing wave sequence the safety isolation zone is a three-dimensional sector area.

HC8600 Type Max. Effect Height Safety Radius around SPARKULAR (a) Safety Distance at Firing Direction (b)
LARGE 4m 1.5m 5m
LARGE I 5m 6m
LARGE II 7m 8m

\ The SPARKULAR® WAVERFALL safety isolation zone is a three-dimensional space with a cross-section of 180° sector enclosed by a and b (check below diagram). We can understand it as a safety area formed by a safety column with diameter of a, height of b rotate of ±90 degrees. Unauthorized persons and objects are strictly prohibited from entering. Depending on the firing sequence / angles the sector area changes accordingly.
\ In windy environment, increase the safety distance according to the wind direction and speed.
\ Sparks and consumables from the machine can lead to serious eye injury. Always wear safety goggles when enter the safety zone.

IMPORTANT NOTICE: Allocate same DMX address to different machine will cause signal interference and leads to malfunction of machine.

Operation Guide

  1. Install SPARKULAR® waver FALL
    a) SPARKULAR® waver FALL suggest to be hanged horizontally.
    b) Make sure the machine is securely installed to avoid falling, make sure to install extra safety rope for each machine.
    c) Check carefully the output nozzle of each machine, make sure the output nozzle is in good shape and there is no powder aggregate.SHOWVEN HC8600 Type Sparkular Waver Fall - waverFALL
  2. Fill SPARKULAR® waver FALL
    a) Open powder bags and fill the feeding hopper.
    b) Choose correct consumable according to the hanging height and safety distance.. SPARKULAR® waver FALL can only use HC8600 LARGE / LARGE I / LARGE II.
    HC8600 Effect length (Low Output) Effect length (High Output)
    LARGE 3m 4m
    LARGE-Ⅰ 4m 5m
    LARGE-Ⅱ 5m 7m

    c) Please be noted that there may sparks or remains fall to the ground. Make sure no flammable material on ground in the safety zone.
    d) Make sure the lid of hopper is locked tight after filling.
    SAFETY NOTICE: Accidentally burning of consumable HC8600 in the hopper can only use sands to extinguish.

  3.  Connect Power / DMX cable
    a) Connect a power cable to the POWER IN socket of SPARKULAR® waver FALL. Connect the other end of power cable to the power source. Make sure power supply in consistent with the rated voltage of the equipment, and the socket must well grounded.
    b) If connect machine in sequence, please connect a power link cable to the POWER OUT of previous machine, connect the other end of the power link cable to POWER IN of the next machine.
    c) The SPARKULAR® waver FALL power supply cable maximum allowed cascade is 6 units (220V version) / 3pcs (110V version). Do not connect exceed units to a single electrical circuit.
    d) Power ON all SPARKULAR® waver FALL.
    e) Assign DMX address for each unit of SPARKULAR® waver FALL. If use SHOWVEN host controller or FXcommander to control the machine please allocate a unique DMX address for each unit of machine.
    If use remote controller to control SPARKULAR waver FALL wirelessly, please set machine to wireless ON status and match machine with remote controller. For DMX cable control please execute below operations (f to h).
    f) Connect a DMX cable to the DMX IN socket of first unit of SPARKULAR waver FALL, connect the male connector end of DMX cable to your DMX controller (FX commander, HOST CONTROLLER, light console etc).
    g) Connect a DMX cable to the DMX OUT of previous machine, and the other end of to the DMX IN of next machine. Connect all devices in series in this way.
    h) Plug in a DMX terminator into the DMX OUT in last unit of machine to improve signal reliability. Signal amplifier is required for long distance (>200m) DMX signal transmission (SHOWVEN DMX splitter 8 with bidirectional signal transmission, thus can get signal feedback from device).
  4. Activate SPARKULAR® waver FALL by swipe RFID card
    a) Swipe an RFID card. Read the card as show below. SPARKULAR® waver FALL shows time remain if read successfully. SPARKULAR® waver FALL report E4 when remaining time is less than 10 minutes.
    b) Please note each RFID card come with 200g package HC8600 can increase single machine 20min working time, the maximum recharge time for SPARKULAR® waver FALL is 30min, when time remain reached 30min, it can’t recharge anymore RFID card.SHOWVEN HC8600 Type Sparkular Waver Fall - swipe RFID card
  5. Programming and Firing
    a) Programming SPARKULAR waver FALL, set the firing sequences etc.
    b) Heating up, it takes few minutes, it varies according to the voltage and environment temperature.
    c) Make sure the prescribed safety zone of related firing sequences are clear.
    d) Suggest to clear material for SPARKULAR® waver FALL before firing.
    e) Firing. In order to prevent overheat in the heating chamber and protect machine, the maximum continuous firing time for SPARKULAR® waver FALL is 60s.
    f) The operator should always have a clear view of the device, so that he/she can stop the show immediately when there is danger.
    g) Running preset sequence No.1 to clear material for SPARKULAR® waver FALL after show, clear material will remove the remaining particles from heating chamber.
    NOTE:
    If use SHOWVEN HOST CONTROLLER ZK6200/6300 to control the firing, please press “F3” to choose “CIRCLE FLAMER-6CH”, then set the firing sequence, as for preset sequence the firing duration is fixed, so please set firing duration 1s. Please do allocate different DMX address for each unit of SPARKULAR WAVERFALL (6 channels), otherwise it will cause signal interference.
  6. Turn Off and clean up
    a) Power off SPARKULAR waver FALL, allow SPARKULAR® waver FALL to cool down.
    b) Disconnect all POWER and DMX cables.
    c) Empty the remaining HC8600 in hopper, and store the remaining HC8600 in a dry sealed bottle for next time use. Never touch the output nozzle of SPARKULAR® waver FALL when empty the hopper. DANGER OF GET BURNT!
    d) Operators can use handheld vacuum cleaner to empty the feeding hopper. Do make sure the machine was cool down when clean it. Do NOT use high-power vacuum cleaners to avoid hot consumables being sucked into the vacuum cleaner from the heating chamber and cause fire.
    e) Clean the surroundings to remove powder residues.

Maintenance

a) Empty the feeding hopper before shipment of machine.
b) Empty the feeding hopper if long time not use, for high humidity environment we suggest to empty feeding hopper after each show.
c) Clear material both before and after the show.
