Weak current College】 【projector electric hanger installation, troubleshooting and debugging.

Projector electric hanger installation requirements:

1, cement ceilings and false ceilings of clearance height must be greater than: hanger fuselage height + interface disc height + universal head height + projector actual thickness, except for special circumstances;

2. proposed ceiling opening: 480 mm x 480 mm (depending on the size of the projector);

3, must be reserved for the maintenance of the mouth, it is recommended that you leave hanger 100 mm to 200 mm, 400 mm ×: 550 mm;

4. adoption of the hanger on top of the four diameter F 12 mm screw hole to F 10 m m of anchors, fastening the hanger in the building's floor. Installation, first select the right location, according to the projector position determines the direction of the hanger, must be determined with the four screw holes for expansion screw hole punch, expansion screws must have sufficient depth to ensure there are enough endurance; don't make hanger near steam pipe, hot-air tube and central air conditioning air, heating equipment;

5. powered should have a dual-lock, power switch, and equipped with 4A fuse tubes, power and control cable application no small cross sectional area of the copper conductor cable 1.5mm2. Power switch and the action button should be as close as possible to the hanger and the action button can directly see the hanger operations hanger enclosure should also have a good grounding. Grounding resistance cannot be greater than 4 Ω, Earth wire with copper conductor cross-sectional area of not less than 1.5mm2 and grounding line with another color wire in order to identify other lines.

• Note: adjust upper/lower limit in place be sure to tighten the captive screws, hanger at ran process orientation will not be allowed to occur.

Projector electric hanger fault and exclusions:

New installation or to use some time projector hanger, a failure occurs, you need to check, you should first call the company, the company permission to self apart. Otherwise the company no longer responsible for warranty. Check, check first whether reliable grounding protection to prevent electric shock accident.

All the same, nothing.

1. check the power supply terminal wire, terminals are there electricity voltage is normal. If you do not have the power you should check the power supply line.

2. If the power terminal voltage normal can check button, there are no motor wiring, fuse loose or not blowing, check on the Terminal and Terminal has no limit switch wiring loose.

3, lifting the frame is in the Terminal, the Terminal limit switch silenced lifting frame cannot stand up; take-off and landing, in the following Terminal Terminal limit switch silenced lifting frame cannot downlink, all is normal.

Press the up or down button will not be able to run, but heard the sound of the vibration and the sound is relatively weak. You should check the capacitor is breakdown, short circuit and its wiring for peeling, circuit breaker. When the motor is severe fever, you should immediately disconnect the power supply to avoid burn out motor. Then check whether the circuit breaker or breakdown of capacitor.

Uplink or downlink lifting frame is not active, but within a larger tank.

1 check the transmission chain is broken or chain.

2 check the sprocket and meshing between the aluminium guide rail is wrong.

3 check the chain wheel and axle locking screws between is loose, so that the shaft will not be able to take the chain wheel rotation and caused four rails running

Out of sync

Descent door does not open automatically.

1 check whether the drag-and-steel door at the perforation is stuck.

2 check the rope in the box of internal somewhere is stuck.

Lifting frame uplink backdoor does not automatically shut up.

Check whether the drag-and-steel doors, such as broken broken selection equal weight of wire rope, according to the drawings represent method replace. Above is the projector installation requirements for electric hanger.
