The Master-trol water management system is versatile and available in several configurations to suit specific job site requirements. The Electronic Valve Controller & system components together provide precise control, electronic water metering and visual indicators.

Each Electronic Valve Controller is capable of directing 12 solenoids. Each controller retains programmed settings in the event of power loss and is powered by a 24VAC, 50 VA, Class 2 UL/CSA listed transformer provided. The controller may be pre-programmed at the factory to specified settings or programmed in the field with an optional computer or programmer.

Versa-Link is an installer provided interface between an optional computer and an Electronic Valve Controller(s). Each link can be up to 4,000 feet long and allows communication with up to 32 Electronic Valve Controllers for a combined capacity of 384 solenoids.

Master-Trol Resources

Master-Trol Controls up to 3,072 Valves

Password Tracking

Password tracking capabilities allow the user to view when and whom has made modifications to the system. In addition, the Master-Trol system can be connected to the facilities existing LAN (Local Area Network) and accessed by other computers on the network using the systems client software.

System Specifications

Each controller is designed to control up to twelve valves. Controllers can be pre-programmed for stand alone installations or linked together and connected to a computer (optional) provided by Acorn Engineering Company. The computer can be used to monitor and program any Master-Trol controller connected to the system.

Master-Trol controllers are linked to the computer using an interface card and up to eight pairs of shielded wire called "links". Each link can run a maximum distance of 4,000 feet from the computer to the last controller with a maximum of 32 controllers per link. The computer can be connected to an existing LAN (Local Area Network) and accessed by other computers on the same network using the provided client software. A handheld programmer is also available to access and program controllers individually or access a number of controllers that are connected to a link.

Existing Features

• Adjustable valve runtimes (Factory or Field Adjustable)
• Adjustable valve lockout Times (Factory or Field Adjustable)
• Ability to enable/disable single or multiple valves (Factory or Field Adjustable)
• Multiple valve options to tailor the function of the valve to the type of fixture it services (Factory or Field Adjustable)
• Remote operation allows user to activate a valve with the click of a button (Factory or Field Adjustable)
• Password protected (Factory or Field Adjustable)

Added Features

• Updated user interface with a "Windows Explorer" view of the facility
• Ability to make global changes by valve groups or valve types
• Ability to assign multiple level user passwords that can limit access to functions or areas of the facility
• Ability to customize 24 hour limitations on water usage or activations. This allows the facility to set a time limit on how long a valve can operate or how many activations are allowed in a 24 hour period. At the end of each 24 hour period, limits are reset. The user can also set up to three timed windows of access which allows access to the valves only during specified times of the day
• Variable lockout which allows the facility to set a specified number of activations a valve can perform within a specified period of time before it imposes a specified lockout time
• Ability to assign valves to queued activation or random activation to prevent simultaneous activations
• Ability to set the valve to "Auto Cycle" which will automatically cycle a valve after a specified period of nonuse
• Ability to cycle a valve from the computer using its programmed parameters
• Password tracking abilities has been added to allow the user to view when changes have been made, what functions have been performed, and by whom
• Ability to track and chart the amount of water usage and activations over specified periods of time
• Extra security has been added that prevents unauthorized access to the Master-Trol system even if the intruder has illegally acquired a copy of the client software

Master-Trol Handheld Programmer

• The Master-Trol controller station parameters can also be set using the Acorn Handheld programmer (-CPT)
• CPT is a low cost alternative to using a PC and has the ability to connect to and control one full link (32 controllers) at a time
• The CPT is recommended for smaller installations - between 1-5 controllers.
• Get information on number of controllers on different links
• Set/change On/Off times
• Enable /disable stations
• Set Valve modes Remote Operation, Paired Operation (PO)
• Set Actuator Modes Single cycle (SC), Cycle Interrupt (CI), Accumulator Mode (AM)
• Troubleshoot and set parameters when access to the central Desktop Computer is not easily available or Master-Trol Controllers are to work stand alone.
