SISTEM DE REGLARE CU
MICROPROCESOR
Reglarea şi controlul unitatilor sunt efectuate prin
intermediul unui microprocesor. Microprocesorul
permite introducerea direct a valorilor set-point si a
parametrilor de funcţionare.
Acest tip de microprocesor poate controla pana la
doisprezece compresoare.
Este echipat cu alarma sonora si vizuala, taste pentru
diferitele funcţii, un sistem de monitorizare continuă
şi un sistem de salvare al datelor în cazul intreruperii
alimentarii electrice.
Display-ul permite introducerea si vizualizarea va-
lorilor set-point.
Principalele functii
Indicarea temperaturii apei de intrare si de iesire;
identificarea eventualelor blocaje si vizualizarea
prin intermediul unor coduri numerice, controlul
unei pompe sau doua; amanare la pornire a alarmei
presostatului diferential; prepornirea ventilatoarelor,
contor orar al functionarii compresoarelor; comutarea
automata a pornirii compresoarelor si a pompelor;
activarea individuala a compresoarelor, protectie
anti-inghet, pornire-oprire la distanţă; indicarea
functionarii; functionare manuala; resetare manuala;
oprire prin sistemul pump-down.
Alarme
Inalta si joasa presiune si protectie totala pentru
fiecare compresor; ventilatoare; antiinghet; presostat
diferential; eroare configuratie.
Accesorii
Interfata seriala pentru PC, panou de comanda la
distanta.

MICROPROCESSOR CONTROL SYSTEM
A microprocessor controls all the functions of the
unit and allows any adjustments to be made. The
set-points and operating parameters are set directly
into the microprocessor.
This type of microprocessor enables the adjustment
of up to twelve compressors.
It has a visual alarm signal, pushbuttons for the
various functions, and offers a continuous control
of the system as well as saving all the data in case
of a cut in the power supply.
Through the display, one can input and have an
indication of set values.
Principal functions
Indication of entering and leaving water temperatu-
re; identification and display of blocks by means of
alphanumerical code; control of one or two pumps;
differential pressure switch alarm delay at start-up;
prestarting of the fans; hour counter of compressors
in operation; automatic changeover of compressor
and pump sequence; compressors start individually
and not together; frost protection; remote on-off;
operation signalling; manual operation; manual
rese; pump down stop.
Alarms
High and low pressure and internal protection on each
compressor; fans; antifreeze; differential pressure
switch; configuration error.
Accessories
Electronic card for connection to management and
service systems, remote display.
