Elevator devices

SenS Lift with commutation protocol CAN open

Next generation of SenS Lift with commutation protocol CAN open is designed for usage in elevator automatisation system, measures the signals from the load cells and is used to control the elevator’s load.

Application

Elevators of various types, including passenger, as the alarm of overload. Furthermore, SenS Lift can be used for measuring other parameters of elevator systems by direct or indirect methods.

Advantages

1. Simplified installation

Elevator load capacity is set at the site (standard load or user value).
Calibration is performed by saving empty car weight and for additional percision known weight (for example, installation personnel weight).

2. Simplified controls

The keyboard allows you to choose the data display mode, enter load capacity, calibrations and other data.
User-friendly English interface (other languages are optional).

3. Universal device for working with different load cells

The device can be used with various types of load cells:

floor (LA series)
wire rope (LB series)
machine bed frame (LD series).

4. Extended relay output functionality

The device generates dry contact relay output signals:

15/20 kg (helps to detect a child’s weight)

50% of net rated load (emergency evacuation)

90% of net rated load (optimization of the elevator)

110% of net rated load.

Relay output "15/20 kg" uses a polarized relay. In case of power outage this allows emergency lightning to go on when passengers are trapped inside.

5. Versatile power supply

The device power supply:

DC 24V
AC 110V, 50-60 Hz
AC 220V, 50 Hz.

Power consumption is less than 5 watts.

SENS LIFT WITH 4 FLOOR LOAD CELLS

Sens Lift with floor load cells is used on elevators with fixed floor and the following load capacities, kg:

400
630
1000
Value, set by user but not more than Net rated load (1,000 kg).
