Control Boxes

Gervall UCM100

The UCM100 module is designed to control the supply of the coil of the electromagnet installed in the Gervall overspeed governor.

The module detects when the cabin is stopped at floor level and with the doors open through the serial and floor level inputs. The coil is stopped to activate the protection, which results in the cabin being protected against uncontrolled movement. The system does not lock the governor when the doors are closed, which allows normal operation of the elevator.

VGOSG-CB01 Control Box

The VGOSG-CB01 Control Box is used with the VG Overspeed Governor to protect against overspeeding and unintended movement. It can also accommodate VG Rope Brakes when used with the VG Overspeed Governor.

The VGOSG-CB01 unit connects directly to the main lift control panel, where it can receive power and signals to tell if the lift doors are open. It also sends signals to the lift to say stop on the next floor if there is a problem, or emergency stop.

The VGOSG-CB01 has an internal battery back-up system for the event of power loss, and switches seamlessly from mains power to battery and back again without the need for manual intervention to reset the governor.

VG Rope Brake Sensor Pack

The VG Rope Brake Sensor Pack is supplied with bi-directional VG Rope Brakes, and is used specifically with the UMD-SRB01 Control Box.

The sensor pack is fitted to one of the VG Rope Brake units, where the sensor wheel is adjusted to align with the ropes to the lift car. Any subsequent movement of the lift car will cause the sensor wheel to rotate, which will in turn send a signal to the UMD-SRB01 Control Box. If the system has determined that the lift car is moving with the car doors open, the UMD-SRB01 Control Box will deploy the VG Rope Brakes to stop the elevator.

UMD-SRB01 Control Box

The UMD-SRB01 Control Box is used in conjuncture with the bi-directional VG Rope Brake to protect against overspeeding and unintended movement.

This unit will connect directly to the main lift control panel, where it can receive power and signals to tell if the lift doors are open, or that the lift overspeed governor is okay. It also sends signals to the lift to say stop on the next floor if there is a problem, or emergency stop.

The UMD-SRB01 has an internal battery back-up system for the event of power loss, and switches seamlessly from mains power to battery and back again without the need for manual intervention to reset the brakes.

RB2a Control Box

The RB2a Control Box is used in conjuncture with a VG Rope Brake to protect against overspeeding in the upward direction.

This control unit incorporates a battery back-up circuit to prevent spurious operation should the power be disconnected for whatever reason. This will keep the VG Rope Brake disengaged and fully operational for a minimum of 3 hours.
