LIGHTING CONTROLLERS
These time switches are designed to operate high load lighting equipment, consisting of a premium quality precision synchronous clock motor and a high amperage switching circuit. All Green Air Products controllers are housed in black anodized brush finish aluminum enclosures which will not break, chip or corrode. Operates with a maximum combined outlet switching capacity of 40 amps. Plug or wire the power cord into a receptacle capable of handling the maximum total combined amperage draw of your equipment load. Make certain that the receptacle, wiring and circuit breaker are adequate and properly suited for this application. Plug lighting equipment into outlets located on each side of controller. Turn clock dial to current time of day. AM and PM is indicated by colored ring on dial face. Push trippers toward the center of the dial for "On" time and leave in the outward position for "Off" period. Timer has 96 non-detachable 15 minute on\off trippers.

The diagram shows a typical installation of the LT4-240 lighting timer. It can be wired directly to a breaker in a service panel or via a sub panel or junction box. Electric range or dryer plugs are an optional, safe and convenient way to provide a hookup. |
4 Light Timer (120 or 240 volt)
|
The LT4-120 provides four 10 amp 120 volt outlet receptacles, each capable of powering up to 1000 watts of lighting equipment. The LT4-240 offers four 10amp 240 volt outlets and will power lighting equipment up to 1000 watts each. |
|
8 Light Timer (240 volt)
|
The LT8-240 (shown on right) provides eight 5 amp 240 volt outlet receptacles, each capable of powering up to 1000 watts of lighting equipment. |
Options
Cord & Plug Set
The 240 Volt models are available with an optional 6ft. 3pole 3wire standard range plug and cord for easy installation. Specify this option with the suffix "C" after the product model number.
Digital Time-switch
Instead of the standard solid-state timepiece, you can choose a digital time-switch. Featuring 24/7 timing, skip-a-day option, and a 90-hour clock battery backup. Specify this option with a "D" after the model number.
Junction Box
As an alternative to the outlets standard on most models, all timers and
contractors are available with a built-in junction box and cover plate on each side to
facilitate hardwiring. This option is suitable where permanent in-line wiring is required
or if equipment does not provide the appropriate plugs. Specify this option with the
suffix "J" after the product model designation.
Back up Battery
The 24 hour clock timer installed in most controllers is available with an internal
self charging nickel cadmium battery. This component is able to maintain time keeping for
up to 90 hours during a power failure. Order this option with the suffix "B".
Latching Relay
This feature disengages the main contractor in the event of a power interruption. The
reset button must be manually pushed to restart appliance. This is useful to minimize the
effects of photo-period interruptions. Use the "L" suffix to include this function.
Temperature Override
An adjustable high temperature defeat circuit may be installed to discontinue
equipment operation during periods when room temperature exceeds your maximum allowable
level. Operation will resume as normal when temperature drops within acceptable limits.
Use to keep lighting related heat from damaging sensitive crops. Use suffix "TO" to specify this feature.
High Amperage
For high amperage solutions please add a HAR-1 to your lighting solution.
Other options, combinations or variations may be available for special applications upon request.
