How the Green Power 4CT 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 4CT will safely and reliably switch on lighting ballasts (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.

This unit will switch from 1 to 4 lighting ballasts or other electrical equipment with a total power consumption of up to 4000 Watts. Each of the 4 mains outlet sockets are individually switchable. Green Power contactors and relay switching units are made under license from Canatronics to their very high standards of construction and manufacture and Grasslin are very well known for making some of the most reliable timers in the industry. The Green Power 4CT is housed in a sturdy metal box and a full unit-width bracket is attached for hanging it on a wall.

How to Use the Green Power 4CT:

The Green Power unit can be hung from a wall by the supplied fixing bracket. With the unit unplugged, programme the timer 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 that 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 mains outlets on separate socket faces. Do not plug them both into the same socket face as this will overload it. 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. No more than 4 lights should be switched, nor should more than 4000 Watts be drawn through it as this will cause the unit to be overloaded.

Although it can handle the switching of up to 4000 Watts, 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 least 18 amps continuously. 4 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 (or over) it's limit.
