We apply the advanced micro-processing network control technology for GRP20 passenger lift. High performance CPU and large capacity storage space, CAN-BUS serial communication produce the extremely strong anti-interference capabilities and perfect lift operation functions. The users can increase special functions according to the specific needs. At present, the modular; intelligent and extensive system, multi-functional serial interface, long-distance monitor technology etc. belong to the advanced control technology in the lift industry.

The matured and reliable serial communication

The concise and reliable serial communication network is adopted between various control sub-systems in order to fulfill a series of the functions such as calling, command, group supervision signal, floor display etc. It greatly reduces the trouble possibilities out of circuit problem, largely enhances the reliability of the lift travel. At the same time, it brings more convenient repair and maintenance to the lift system.

Smooth start, quiet moving

SRH GRP20 passenger lift special invertor takes the control theory of the advanced technology as the foundation. The start, acceleration, brake curves are designed according to the ergonomic theory in order to get the finest coziness. It is a genuine current vector control variable frequency drive system.

Top advanced door operator system

SRH Lift applies the advanced VVVF variable voltage and variable frequency control technology to the lift door operator system so as to ensure the smooth lift door and quiet switch. What is more, the self-learning door load detector increases the sensitivity of the lift door switching on/off. It monitors the variation of lift door load on every floor. Automatically rectifying the most appropriate open / shut speed in every floor so as to guarantee the security and reliability.

Safety functions

If the elevator does not leave door zone with in the designated time after it gets started, it will stop the operation

Inspection operation

When the elevator enters into inspection operation, the car travels at inching running

Fault self-diagnosis

The controller can record 62 latest troubles so as to quickly remove the trouble and restore the elevator operation

Repeated door closing

If the elevator cannot close the door due to certain obstacle or interference, the elevator will reopen or re-shut the door until sundries are eliminated

Up/down over-run and final limit protection

The device can effectively prevent the elevator from surging to the top or knocking the bottom when it is out of control

It results in more safe and reliable elevator travel

Down over-speed protection device

When the elevator downs 1.3 times higher than the rated speed, this device will automatically cut off control mains, stop the motor running

Safety tongs act to force the elevator stop in order to ensure the safety

Upward over-speed protection device

When the elevator up speed is 1.3 times higher than rated speed, the device will automatically decelerate or brake the elevator
