CEDES ESPROS/VOL is a volume recognition product that can analyze the occupied area in an elevator car. It monitors the entire surface area and calculates the area occupied by passengers and objects in the car. By capturing and comparing images, the system can detect any changes and generate new output signals. This product can improve the efficiency of elevator operation.
The ESPROS/VOL is an optical sensor that measures occupied floor area inside an elevator car. It uses a CMOS image sensor of about 100 000 pixels, processes images with an on‑board DSP, and provides relay and LED outputs indicating whether the car is over or under the configured occupancy limit.
The manual describes wiring, relay functions, LED indicators, RS‑232 PC interface, installation options (top‑mount or wall‑mount), startup and calibration procedures, removal steps, safety warnings, and part identification numbers. This manual is written in Chinese.
| Sensor type | Optical sensor with ~100 000‑pixel CMOS image sensor |
|---|---|
| Supply voltage | +24 V DC |
| Relay outputs | Two relay outputs (NO/NC) for occupancy status |
| Potentiometer functions | P1 sets occupancy limit, P2 controls buzzer, P3 sets recalibration time |
It can be top‑mounted (ESPROS/VOL‑V) on the elevator ceiling or wall‑mounted (ESPROS/VOL‑A) on the car wall, with recommended positions shown in the manual.
