Electric control board
Electric control board: The electric control board is constructed and wired in accordance with
Directives 73/23/EEC and 89/336/EEC and related standards. The board may be accessed through
a door after the main switch has been turned off. All the remote controls use 24 V signals powered
by an insulating transformer situated on the electric control board.
NOTE
The mechanical safety devices such as the high pressure switched are of the kind
that trigger directly; their efficiency will not be affected by any faults occurring in
the microprocessor control circuit, in compliance with 97/23 PED.
Microprocessor control
The microprocessor built into the unit allows the different operating parameters to be controlled
from a set of pushbuttons situated on the electric control board:
•
Alarm management:
o
Dirty filters alarm (optional);
o
Air flow alarm;
•
Alarm signalling;
•
Display of operating parameters;
•
RS232, RS485 serial output management (optional).
See microprocessor control manual attached for further details, also in relation to customer
specifications.
