How the Green Power Contactors Eco-Switch w/Grasslin Timer Works

Most plug-in timers available on the market today will fail if they are used to switch on and off a load such as a grow-light ballast. The Green Power Contactors will safely and reliably switch on grow-lights (and/or fans etc.) by means of highly rugged internal electrical switching components according to the schedule that you set on the integral Grasslin timer on the front.

The Green Power Contactor will switch either 1 or more lighting ballasts or other electrical equipment with a total power consumption of up to 4200 Watts depending on the unit in question. Both of the mains outlet sockets are individually switchable. The whole lot is housed in a sturdy metal box and a full unit-width bracket is attached for hanging it on a wall.

How To Use

How to Use the Green Power Contactors Eco-Switch w/Grasslin Timer

The Green Power unit can be hung from a wall by the attached fixing bracket. With the unit unplugged, programme the timer on the front of the Green Power Contactors by moving the tabs on the face of the Grasslin timer to the outer position for those times that you would like power to be on, and set the others to the inner position for the times you would like the power to be off. Each segment corresponds to 15-minutes. A pencil or other small item can be handy for pushing the segments in or out with.

Move the timer-face clockwise until the current time lines up with the arrow. The hands on the clock in the centre will then also correspond to the correct time. There is an override switch to the lower-right side of the clock. This can be set to "0" for "Always Off" or it can be set to "1" for "Always On". The centre position of the switch is for "Timed On" and this will be the normal setting for the unit when it is in use to switch your lights on and off according to your set programme.

Plug your ballasts, fans or other electrical items to be switched, into the sockets on the Green Power Contactor Switching Unit. Make sure that the switches on the outlets are in the "On" position. Insert the rubberised mains plugs into separate mains outlets. Ensure the timer override switch is in the middle position. The contactor will now switch your lighting system on according to the programme set on the timer.

Although the Green Power Contactors can handle the switching on of numerous ballasts, it is worth bearing in mind that traditional (non-digital) HID lighting ballasts draw a considerable surge at switch-on which is well in excess of their normal running wattage. There must be enough spare capacity on the mains circuit that the Green Power contactor is plugged into to provide at extra amps continuously. To many lighting ballasts being switched on simultaneously may cause the circuit breaker in your consumer unit to trip if that circuit is being run too close to it's limit.

Note: Do not exceed the wattage limit on any of the Green Power Contactors
