Installation Tips

For this reason, each output circuit should be protected with a fast blow fuse -and-- you should not change bulbs with power "ON.” Also, during initial installation, do not apply power to the controller until AFTER you have manually wired power to each circuit individually one at a time to see them light up properly with no problems. After all, circuits have been checked individually; THEN you can apply power through the solid-state control unit. Test all circuits before control units are installed. Don't use the control unit as an expensive fuse.

Do not replace or change bulbs while the power is on. Mark the bad bulbs with a piece of tape or something ---- then turn the power off before replacing any bulbs. The adhesive glue between the glass globe and the metal threaded base will often break loose (especially on the cheaper imports). This allows the two wires inside the socket to twist together as you try to unscrew the bulb--- which creates a permanent "dead short" and will destroy the semiconductor Triac, which provides output for this circuit ( if the power is on at this time). Always turn the power "off" before replacing any bulbs. A fast blow fuse should be installed in line with each circuit to protect the semiconductor inside the control unit from being destroyed due to this short circuit condition. When the internal semiconductor (Triac) is destroyed, it usually shows up as a "solid on" condition for the circuit subjected to the short circuit.

It is recommended that fast-blow fuses be installed on each of the output circuits so that they will have a chance to protect the semiconductor (Triac) devices inside the chase control units. The fuses should be sized just large enough to allow the expected (calculated) load on the individual circuit to pass --- maybe increase the fuse size by 1 amp to avoid nuisance blows. -Perhaps use a 3A to 6A fast blow fuse (smaller is better) on the chase control units depending on your calculated load. Heavier fuses can be used for each circuit on the heavy-duty 20 amp units. In-line fuse holders are cheap, usually less than $1 each. The warranty does not cover units that have been damaged due to short circuit conditions. The solid condition described above will indicate that a short circuit has occurred.

DO NOT install solid-state controllers above the ceiling or in the attic because temperatures in this non-air-conditioned space run too hot and eventually lead to overheating and premature failure under load. A preferable installation location would be in the same temperature environment as people.

Do not mount solid-state controllers in any location where they can get wet. Water Proof boxes are required for outdoor installations. Keep the control unit dry. --- Indoor installation is preferred. If the installation is outdoors, the enclosure must be water-tight yet still have adequate room (enclosure volume) to allow for any heat generated to be appropriately dispersed to prevent overheating. This is especially true if control units are handling heavy wattage lamp loads.
