Acorn Battery Powered Time-Trol Plus Valve Selection
Model MVC-BAT
Battery Powered Time-Trol Plus Valve Selection
Valve Suffix Option -MVC-BAT, Battery Powered Modular Valve Controller is for use where electricity is not
available and it provides an Acorn Time-Trol Plus System for water metering through precise electronic control of
the solenoid valve provided.
The Time-Trol System uses a pneumatic actuator requiring less than 5 pounds of push on the fixture pushbutton
to activate the timing cycle. The pneumatic actuator tube easily attaches to the Modular Valve Controller. 9 Volt
Battery Powered Time-Trol Plus Controller has a plastic
housing with a compartment for a rectangular 9 Volt battery. Battery to be supplied by others. Factory tests have
provided over 90,000 operation cycles with a standard alkaline battery.
Controller rotating adjustment knob selects valve metering length and lockout time. Valve metering time has
eleven settings between 4 seconds and 7 minutes. Lockout time has twelve settings between 0 seconds and 1.5
hours. Controller is to be located within 10 feet of activating pushbutton. Controller supplied with 3 feet of wiring
for connection to solenoid control valve installer should increase length of 14 gauge wiring as required, battery
cycle life will decrease approximately 5% for every additional 10 feet.
Cycle Interruption is a standard feature that enables the user to terminate the metering cycle after 5 seconds of
valve " ON " time by simply pushing the fixture pushbutton again.
Status Indicator Light is provided on each Time-Trol Plus Modular Valve Controller. It is activated by pressing
either the fixture pushbutton or the controller STATUS/SET button and displays one of the following conditions:
1 Flash = Normal Status 4 Flashes = Lockout Confirmed
2 Flashes = Lockout Active 5 Flashes = Valve Time Set To Off
6 Flashes = Start-Up Initialization
NOTE: When the battery power gets low, the Status Indicator Light automatically starts flashing once every five
seconds.

Acorn Time-Trol Valve Controller
Model -MVCI-MVCFV
The Acorn Modular Valve Controller (-MVC/-MVCFV) is provided with quick connect terminals for easy connection
to both the solenoid valve and a low voltage 24 VAC transformer. Transformer to be provided by others, unless -TF
Transformer option is specified and ordered from Acorn. Controller can be remotely located up to 100 feet from the
actuating button and 50 feet from the solenoid valve using additional tubing and wiring. For security installations,
the controllers could be in the chase area or centrally located in guarded control rooms.
Colored Indicator Lights are provided on each Modular Valve Controller to permit quick and easy diagnosis in
the unlikely event of a malfunction. For instance:
* As long as there is power to the -MVC the amber " power " light will remain on.
* The red " switch " light goes on upon pushing in the pneumatic actuator
pushbutton, and shuts off upon release of the pushbutton.
* The green " valve " light stays on indicating that contacts are closed, and the solenoid valve is open. Green light goes
off at the end of the timing cycle.
Suffix Option -Cl Cycle Interrupt is optionally available with -MVC valve metering. This feature enables the user
to terminate the metering cycle at any time by simply pushing the pneumatic actuator pushbutton on the fixture.
This option is not applicable to -MVCFV flush valve lockout control.
For Water Metering: Provide and install the Acorn Time-Trol System Option -MVC, Modular Valve Controller with
optional -Cl , Cycle Interrupt feature using low voltage, 24 VAC power (by others). Provide a solenoid valve made
with non-corrosive wet parts.
For Flush Valve Lockout: Provide and install the Acorn Time-Trol System Option -MVCFV, Modular Flush Valve
Controller with solenoid type flush valve using low voltage, 24 VAC power (by others). Stainless steel fixture pushbutton
shall be vandalresistant and shall pneumatically actuate the Modular Valve Controller, with no electrical
impulse at the pushbutton. Pushbutton shall require no more than 5 lbs. pressure to activate the system. Valve
timing/lockout cycle shall have 10 preset intervals ranging from 1 second to 9 minutes, easily adjustable with a knob.
Modular Valve Controller shall have colored lights to indicate system is functioning and permit easy trouble shooting.
