1 - Safety summary
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 parts;
•
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.
Electrical safety
•
Turn OFF power supply before connecting the device;
•
connect the unit according to the explanation in the section ”4 – Electrical
connections”;
•
connect Zero Setting/Preset and Counting direction inputs to 0VDC, if not
used;
- to set the encoder to zero/preset, connect Zero setting/Preset input to
+VDC for 100 µs at least, then discVDC; normally voltage must
be at 0VDC; zero/preset setting must be performed after Counting
direction setting; we suggest performing the zero/preset setting when
the encoder is in stop;
- Counting direction: increasing count = connect to 0VDC; decreasing
count = connect to +VDC;
•
in compliance with 2004/108/EC 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;
