1 – Safety summary
1.1 Safety
Always adhere to the professional safety and accident prevention regulations
applicable to your country during device installation and operation;
installation and maintenance operations have to be carried out by qualified
personnel only, with power supply disconnected and stationary mechanical
devices;
device must be used only for the purpose appropriate to its design: use for
purposes other than those for which it has been designed could result in
serious personal and/or the environment damage;
high current, voltage and moving mechanical parts can cause serious or fatal
injury;
warning ! 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 equipment;
Lika Electronic assumes no liability for the customer's failure to comply with
these requirements.
1.2 Electrical safety
Turn OFF the power supply before connecting the device;
connect according to the explanation in the ”4.1 Electrical connections”
section on page 12;
connect Zero Setting input to 0Vdc, if not used; to zero set the encoder,
connect Zero setting input to +Vdc for 100 µs at least, then discVdc;
normally voltage must be at 0Vdc; zero set must be performed after
Counting direction setting; we suggest performing the zero set when the
encoder is in stop;
connect Counting direction input to 0Vdc, if not used; to have count up
information when the measuring system moves as shown in Figure 2 (see the
arrows) = connect to 0Vdc; to have count up information when the
measuring system moves in the direction opposite to the movement shown
in Figure 2 (see the arrows) = connect to +Vdc;
in compliance with 2014/30/EU norm on electromagnetic
compatibility, following precautions must be taken:
- before handling and installing the equipment, discharge electrical
charge from your body and tools which may come in touch with the device;
- power supply must be stabilized without noise; install EMC filters on device
power supply if needed;
- always use shielded cables (twisted pair cables whenever possible);
- avoid cables runs longer than necessary;
- avoid running the signal cable near high voltage power cables;
- mount the device as far as possible from any capacitive or inductive noise
source; shield the device from noise source if needed;
- to guarantee a correct working of the device, avoid using strong magnets on
or near by the unit;
