2ton hoist overload limiter,
CE hoist overload limiter,
6 Digit Display overload limiter
2ton Capacity Load Limiter for Building Hoist/Construction Elevator with 6 Digit Display for Overload Protection
The overload limiter is a safeguarding device, which is specially designed for buidling hoist/construction elevator. The overload limiter can make alarm with sound and light, protecting the building hoist/construction elevator from being overloaded.
|Display mode||6-digit display||Rated load||2t|
|Working temperature||-20~60℃||Sensor working voltage||DC5-12V|
|Operating humidity||95%||Sensitivity of the sensor||1.0000Mv/v|
|Comprehensive error||≤1%F.S||Installation||Slot type|
|Alarm output||AC250V/7A||Action error||≤1%F.S|
|Overload early warning||≥ 95% of the rated weight(resettable); state of the relay: coil power-losing; closing of normally-closed contact; state of the buzzer: intermittent ringing (one second with two seconds interval)|
|Overload alarm||≥ outage happens when 100% of the rated weight lasts one second(resettable); state of the relay: coil is powered, normally-closed contact is off; state of the buzzer: rapid ringing for two seconds.|
|Instant alarm||≥ at 105% of the rated weight (immediate power off); state of the relay: coil is powered, normally-closed contact is off|
|Alarm release||Alarm relieves automatically when the load is less than rated weight.|
1. Perfect solution for gondola/suspended platform's overload protection, with classic plastic shell, the load limiter is easy for installation;
2. High accuracy: Controller's measurement accuracy is better than 1%, which is much better than analog singal indicator;
3. Display: 6 digit display, 0000.00-9999.99, the limiter can acheive high accuracy weighing results;
4. Built-in battery: the overload limiter can work for 8 hours without power supply and will charge itself automatically once the power is resumed, making sure the building hoist/construction elevator is monitored all the time.
5. Dual way normally closed contact for power cut-off; extra buzzer and display can be connected to the overload limiter for convenience.
6. Support RS232/485 communications, can be connected with monitor screen or PC.
7. Black box function: the overload limiter can record the data up to 4,000messages of load/overload during operation
8. Easy debugging, just press one button to correct all the weighing date without actual weights;
