Controller for reverse osmosis installations

– Menu driven programming utilizing “two line” LCD-display.
– Choice of languages.
– Adaptable to user specific requirements by built-in programmable options.
– Simple control utilizing easy to follow symbols.
– Universally applicable for various sizes of installation.
– Desalinated water production controllable by hand or level switches.
– Control of the maintenance situation by means of a code choice possible.
– Programming a service telephone number possible.
– Substantial status information employing INFO key: actual input and output conditions, service telephone number, software version, programming situation of the annunciation and malfunction relays, rinse interval, rinse times, instrument probe cell constants.
– Large green LCD-display showing permeate and raw water conductivity plus the relative.
– Permeate-conductivity as a percentage value of the raw water conductivity or raw water temperature.
– Adaptable communication link with the central control post.
– Interface 0(4)-20 mA and RS 232 in preparation.
– Input : production-stop, storage tank full/empty, excess pressure, low pressure, concentrate-monitoring or alarm reset, motor protection switch, temperature feeler (optional).
– Integrated conductivity meter with automatic range switching.
– Conductivity range accordin to the instrument probe cell constants fro 0,5 to 1 00 000 uS/cm.
– The instrument probe cell constants programmable from 0,01 to 10,00 cm-1
– Manual or automatic temperature compensation.
– Duplicate conductivity meter and temperature reading as an available option.
– Thermo switch with annunciation contac for 115/230 Volt pressure pump as available option
– Output : pressure pump (protection), input valve, rinse valve for concentrate and permeate, annunciation and malfunction contact.
– Security of program information against supply failure, as program information is stored without accu.
– Large capacity microprocessor with “Watchdog”, illegal “Operation code” and frequency monitoring.
– Manufactured in accordance with EMC codes of practice; by means of galvanic isolation between the micro-processor and the in-and output circuits, plus extra built-in filter.
