1, Overweight hoistscage' protection: When the goods in the cage are more than maximum loading weight, the machine would be automatic shutdown and appear screen prompts.
2, inter-layer door chain protection: When any one of the inter-layer safety door is not closing well or hoists’ cage running suddenly opened, the machine automatically stop running, and have the corresponding prompt.
3, hoists’ cage safety door protection: When hanging cage (security) door is open, the machine should not run and have the corresponding prompt.
4, phase sequence protection: When the power supply phase sequence is incorrect or missing phase, the machine automatically disconnect the power and have the corresponding prompt.
5, over summit, over ground protection: reliable mechanical and anti-summit device (anti-rather than taking it at the end of installation), to ensure over summit and over group of the accident will not happen.
6, motor short circuit or overload protection: When the electrical short circuit or over-use of its rated current, voltage, the machine automatically cut off power.
7, data protection: At any time, switch off the power supply, built-in storage will not lose any data.
8, sensor failure protection: When the sensor fault and result in no signal, it will be detected by computer and promptly shut down, thereby avoiding the failure happened.
9, an external control line low-voltage protection: all external control lines, including upper and lower limit switches, inter-layer door, safety door switches, and pulse sensors are in line with the International Electro technical DC24V safety standards.
10, bell prompted functions: output bell signals before running, the machine remind workers to leave cage of hoists, to protect the personal safety of workers.
