Overload Limiter, Over Load Protector with Loading Cell, Weigh Sensor
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.
Four, debugging:
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,
Method one:
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%.
Method 2:
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.
digital flicker, that is, set success.
