Plastic Silver Housing IP68 Protection Class Overload Limiter for Wire Rope Hoist
One, product technical parameters:
1, all the stations were set:
2, early warning: lifting weight reaches 90% of the rated lifting weight, intermittent sound and light alarm, but not to cut off the circuit.
3, delay emergency alarm: lifting weight reaches 105% of the rated lifting weight, delay for 2 seconds a continuous sound and light alarm, and cut off the circuit, but does not affect the decline.
1, immediately alarm point: lifting weight reaches 130% of the rated lifting weight, immediately issued a continuous sound and light alarm, and cut off the circuit.
2, using the environment: - 10 ° C ~ + 60 ° C, humidity below 90% RH.
3, power supply: ~ 380 v + 10%, 50 hz.
4, relay contact capacity: ~ 250 v, 10 a.
Second, the installation instructions:
When installation, as shown, installed in a fixed rope, such as no fixed rope, can also be installed in a balance wheel at the bottom of the steel wire rope, balance pulley 20 ~ 30 cm distance.
Note: when installation, pressure piece of grooves on the steel wire rope, gland nut sensor screws into briquetting and close together.
Three, connection details:
This product has four lines, two root power (red, yellow), and two control (blue, green).When the power
On the control of the 36 v terminals in the cabinet, the two control line series is on the rise of contactor coil control loop, as shown.
After completion of the overload limiter installation need to debug,
The first step: reset,
In the condition of empty hook, hold the meter box - > 0 please key for 3 seconds, the Numbers on the meter to zero and continuous flash for 3 seconds, is reset successfully.
The second step: I set the alarm point,
Use crane to lift first rated load weight (note: must be hung from the ground), and then hold the meter box on the M key for 3 seconds, rated weight on the digital display instrument, and continuous flash for 3 seconds, or set a success.(recommended)
Example: a 5 t single beam crane, right after install the corresponding 5 t overload limiter, when empty hook to hold the first "0" button 3 seconds, and then put the 5 t weight lifting off the ground (must) from the ground, and then press "M" button 3 seconds set value, the full set after the action point load in the range of 5.25 t + / - 5%.
With crane lift a weight of a known weight first (note: 50% of the rated weight must be greater than the weight of the weight, and be sure to hang off the ground), and at the same time hold down the "+", "-" key about 3 seconds after the show "0.0" and then press the "+" input to lift heavy things again according to the weight of the "M" key 3 seconds, the digital display to lift heavy objects on the instrument and the weight of the scintillation for 3 seconds, which set a success.(this method for emergency plan, emergency alarm error when debugging by this method will be slightly larger, so it is not recommended)
Example: a 5 t single beam crane, right after install the corresponding 5 t overload limiter, when empty hook to hold the first "0" button 3 seconds, and then put a weight of a known weight Hanging from the ground (heavy weight must be greater than 2.5 t and must be from the ground), and at the same time hold down the "+" and "-" key about 3 seconds to display "0.0" and then press the "+" input to lift heavy weights known again according to the weight of the "M" button 3 seconds to digital flicker, that is, set success.
