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 power off before replacing any bulbs. Very often the adhesive glue between the glass globe and the metal threaded base will break loose, (especially on the cheaper foreign imports). This allows the two wires inside the socket to twist together as you try to un-screw the bulb--- which creates a permanent "dead short" and will destroy the semiconductor triac which is providing output for this circuit ( if the power is on at this time). Always turn power "off" before replacing any bulbs. A fast blow fuse should be installed in line with each circuit in order to try 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 which has been 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. Warranty does not cover units which have been damaged due to short circuit conditions. The solid on 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 runs too hot and will 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 which is generated to be properly dispersed to prevent overheating. This is especially true if control units are handling heavy wattage lamp loads.
Do not mount solid state control units adjacent to - or in the same box container with neon transformers or Fluorescent ballasts. The neon transformers will eventually run very hot as time progresses and this heat may cause the solid state controllers to overheat and fail. Also, the neon transformers (especially the electronic transformers ) usually generate a very noisy electric static field in the area around them and this noisy electric field may have a tendency to disturb the computer chips inside the solid state chase controller units thereby causing some undesirable random lighting pattern sequences.
