DESCRIPTION
The pGD1 and the Mini-pGD are the new interfaces for the complete management of the units with pCO boards.
La arquitectura consta de:
Motherboard with microprocessor for the execution of the control program, equipped with the necessary terminal to connect the
control elements of the equipment; Valves, compressors, fans, ...
The program remains written to the EPROM and the parameters entered are stored in the EEPROM, thus maintaining the program even
in the absence of power.
The motherboard also allows connection to a network of several motherboards called the pLAN network and also allows the connection
to a serial Supervision / Teleassistance line via RS 485 protocol, CAREL communication protocol, MODBUS protocol, LONWORKS
protocol and even WEBGATE for remote management.
Terminal controlled by a microprocessor, with display, keyboard from which the programming of the control parameters and
fundamental operations of the equipment are carried out.
The user terminal allows:
Initial machine configuration with password protected access.
The possibility to modify the fundamental parameters of the equipment with password protected access.
Modification at any time of set points, stop / start of the unit, change of summer / winter cycle and schedules in case of incorporating
a clock board, without needing a password.
Display of possible system alarms and acoustic warning.
El funcionamiento de los mandos pGD1 y Mini-pGD son muy similares, la información en pantalla es idéntica. Mostrándose en un tamaño
menor en el Mini-pGD. Los dos constan de pantalla retro-iluminada.
The only differences are:
The size
Key symbols
Illuminated keys only in pGD1
The pGD1 can be mounted in panel and outside and the Mini-pGD can only be mounted in panel.
