Hyden Engineering 1 Enviro-Spray™ 1.1 Background Enviro-spray™ was specifically developed to be a plug and play system that optimises the use of limited water supplies while still maintaining the dust control barrier required by regulations. The user interface has been simplified by replacing the old dial type control with a user-friendly up-down push button control, foot pedal stop-start switch and LCD display.

Hyden Engineering Maintenance was also kept top of mind in the development of the Enviro-spray™ system and this has been optimised by the use of separate modules for each key component, oversize filtration and with conditional indicators giving feedback to the operator. Each key control valve used in the Enviro-spray™ system has its...
Hyden Engineering 2 System operation 2.1 System controls 2.1.1 Spray Toggle Switches (typical 5 spray system illustrated, layout may vary) Spray System Switch This is the main power switch used to turn the Enviro-spray System on. Spray Nozzle Switches These switches are used to turn on the corresponding spray heads.
Hyden Engineering 2.1.5 Vari-Spray Buttons The increase button steps up the variable spray water volume by one step with each button push. The maximum setting will be as was set during the electric default system setup procedure. LOW, 20%,40%, 60%, 80%, HIGH...
Hyden Engineering 2.1.8 Display window Messages will be displayed in this window to advise the status of spray operations. 2.1.9 Pedal Indicator The Pedal indicator will show the status of the foot pedal (On or Off). The foot pedal will always default to on when the spray system is turned on.
Hyden Engineering 2.2 Using the spray system 2.2.1 Basic spraying Step1) Turn the Spray System On Turn the spray system on by switching the ‘SPRAY SYSTEM’ toggle switch to the ‘ON’ position. The system will go through a short startup process and the display will show “System Standby”.

Hyden Engineering Step3) Using the Pause Function. The Pause Switch is used to stop the pump and sprays in one action. The display will show “Sprays Stopped”. Use the Pause Switch again and the system will revert back to the setting prior to operating the Pause Switch.
Hyden Engineering 2.2.2 Spot spraying Step1) Turn the Spray System On Turn the spray system on by switching the ‘SPRAY SYSTEM’ toggle switch to the ‘ON’ position. The system will go through a short startup process and the display will show “System Standby”.

Hyden Engineering Step3) Using the spot spray. Spot Spraying is based on distance rather than time and as such should be fully understood before operating. The Spot cycle is based on equal distances such that ‘wet’ distance and ‘dry’ distance are as per the selection.
Page 12
Hyden Engineering Step4) Adjusting the Spot Spray. There are 6 different Spot Spray wet/dry distances available that are selected by pushing the appropriate button to either increase or decrease the current setting. The system has been setup for your site with a default wet/dry distance.
Hyden Engineering 2.2.3 Road speed control Step1) Turn the Spray System On Turn the spray system on by switching the ‘SPRAY SYSTEM’ toggle switch to the ‘ON’ position. The system will go through a short startup process and the display will show “System Standby”.

Hyden Engineering Step4) Cannon nozzle adjustment The Jet and Fog switch can be used to change the pattern of the cannon water spray from Jet to Fog or Fog to Jet. Step5) Using the Pause Switch with cannon The Pause Function can be used at any time to pause the Cannon water flow.
Hyden Engineering 2.4 Using the Auxiliary 2.4.1 Auxiliary systems Step1) Using the auxiliary mode The Auxiliary Mode is provided so that any manual valve type devices (fire hose, manual cannon etc) can still be used with Vari-rate spray control and the foam injection systems.
Hyden Engineering 2.5 System controls 2.5.1 Tank level monitoring system Tank Water Level (if installed) will provide continuous indication warnings of current tank levels. The display will be updated with the current water level every 10 seconds. If the display line is overwritten by another message the level gauge will return after 10 seconds.
Hyden Engineering 2.5.2 Speed sensor monitor The Pump Motor Speed Sensor is a critical part of the spray control system. This sensor continually feeds back to the control module so that it will always know what the motor speed is doing. If...
Hyden Engineering 2.5.3 Motor Filter sensor The system is fitted with a pressure filter that filters the oil going into the pump motor. This filter is fitted with a clogging indicator that is constantly monitored by the system. The Motor Filter Blocked fault alarm is a critical alarm that if ignored can cause contamination of the hydraulic oil.
