NOTE
NOTE NOTE NOTE NOTE: The EIA standard establishes that by RS-485 interface
it is possible to connect up to 30 devices with one remote
master unit.
The serial interface of these instruments is based on “High
input impedance” transceivers; this solution allows you to
connect up to 127 devices (based on the same transceiver
type) with one remote master unit.
MAINTENANCE MAINTENANCE
MAINTENANCE MAINTENANCE MAINTENANCE
1) REMOVE POWER FROM THE POWER SUPPLY TERMINALS
AND FROM RELAY OUTPUT TERMINALS
2) Remove the instrument from case.
3) Using a vacuum cleaner or a compressed air jet (max. 3 kg/
cm 2 ) remove all deposit of dust and dirt which may be
present on the louvres and on the internal circuits trying to
be careful for not damage the electronic components.
4) To clean external plastic or rubber parts use only a cloth
moistened with:
- Ethyl Alcohol (pure or denatured) [C

OH] or
- Isopropil Alcohol (pure or denatured) [(CH

5) Verify that there are no loose terminals.
6) Before re-inserting the instrument in its case, be sure that it
is perfectly dry.
7) re-insert the instrument and turn it ON.
