1. Safety 

1.1 General safety 

 

Installation and maintenance operations must be carried out by qualified personnel only, with power 
supply disconnected and stopped mechanical parts. 

 

The device must be used for the purpose appropriate to its design only. The use for purposes other 
than those for which it has been designed could result in serious personal or environmental damage. 

 

High current, voltage and moving mechanical parts can cause serious or fatal injury. 

 

Do not use in explosive or flammable areas. 

 

Failure to comply with these precautions or with specific warnings elsewhere in this manual violates 
safety standards of design, manufacture and intended use of the device. 

 

WayCon assumes no liability for the costumer’s failure to comply with these requirements. 

 

1.2 Electrical safety 

 

Turn OFF the power supply before connecting the device. 

 

The electrical connection of the sensor must be carried out according to the explanation in section 

3. 

Electrical connection

 

 

Unused wires must be cut to different lengths and insulated separately. 

 

In  compliance with the norm 2004/108/EC on electromagnetic compatibility, the following 
precautions must be taken: 

 

Before handling and installing the equipment, discharge electrostatic charges from your 
body and tools which may come in touch with the sensor. 

 

Power supply must be stabilized without electrical noise. Install EMC filters on device power 
supply if needed. 

 

Always use shielded cables.  

 

Avoid cables that are longer than necessary. 

 

Avoid running the connection cable near high voltage power cables. 

 

Avoid installing the sensor near sources of capacitive or inductive noise. Shield the sensor 
from those noise sources if necessary. 

 

To ensure a correct working of the sensor, avoid using strong magnets on or near the 
measurement system. 

 

Do not stretch the cable. Do not pull or carry the sensor by the cable. Do not use the cable as a handle. 

 

1.3 Mechanical safety 

 

Install the device following strictly the information in section 

2. Mounting instructions

 

 

Mechanical installation must be carried out by stopped mechanical parts. 

 

Do not open the housing of the sensor. 

 

Delicate electronic equipment! Handle with care! Do not subject the sensor to knocks or shocks. 

 

Protect the sensor against acidic solutions or chemicals that may damage it. 

 

Make sure, that the sensor and the magnetic tape are not jammed by chips, fillings or turnings.
