Use:
The ZSP-01 external parking system is intended for controlling the process of vehicle parking/docking.
Construction:
The ZSP-01 external parking system consists of an ultrasonic sensor and a control box.
The ultrasonic sensor enables distance measurement from 0,3 m to 2,75 m*. It is provided with filters to ignore small objects and return only the results for objects with strong acoustic echo. The device self-calibrates in real time (supply voltage, humidity, background noise).
The control box is made of plastic and provided with 5 packing glands to seal the outgoing cables tightly. Two signalling devices (internal and external ones) may be attached as well as an ultrasonic sensor. Additionally there is a transmitter outlet changing the status when the distance from the vehicle is smaller than or equal to the lower limit.
The optional ZSP-01 elements may be extended for other W2 products enabling external signalling (SO-Ad3 signalling device) and internal signalling (WS-Ad signal tower). With such solution the user obtains a complete system to enable measuring the distance between the vehicle being parked and other objects as well as light signalling of the particular process stages.
Products by other manufacturers (PLCs, other signalling equipment or actuators) may be connected to ZSP-01.
* For larger quantities ordered there is a possibility to extend the upper limit to 7,5 m.

Control:
After the control box is connected to the mains, the setup of the switches responsible for the upper and lower limits is checked in accordance with tables 1 and 2. Change in the setup range may be done during the device operation.

Table 1. Lower limit setup. Table 2. Upper limit setup.
Based on the information forwarded by the ultrasonic distance sensor, the selected range and the control input, the device generates a controlling signal for W2 signalling devices. The table below presents interdependence between the distance and the optical signal. If a tower is mounted inside, the change of light from red to green takes place with a 5-second delay.

Table 3. The colours of the signalling devices depend on the distance.
Moreover, if the distance of the vehicle from the sensor is equal to or smaller than the lower limit, the status at the transmitter output changes. With the use of the jumper mounted on a printed circuit board it is possible to select the output signal for the external control system. The system enables selection between 24 V DC signal and NC contact of the transmitter.
Optionally, there is a possibility to connect the system such that a mechanical button is replaced with a sensor of platform standstill location, which automatically signals the end of transloading.
NOTE!!!
If the ultrasonic sensor is not connected or if the sensor’s cable is damaged, the signalling devices blink with red light at the frequency of 1 Hz.
