Description

The OS3050/3051 ro controlleris universal applicable for automatic monitoring and control of reverse osmosis plants. The controller is equipped with a conductivity meter optional is a second conductivity meter and temperature meter. Also optional is a circuit board with two recorder outputs (0(4) – 20 mA). There are five possible stages : "Stand by", "Production", "Rinse after production", "Rinse during standby" and "Maintenance". Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.

Features

• Menu driven programming utilizing "two line" LCD-display.
• Choice of languages (English, French, German, Italian, Spanish or Dutch).
• 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 LED-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.
• Optional card for 2 recorder outputs 0(4)-20mA (conductivity / temperature).

• 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 according to the instrument probe cell constants from 0,1 to 1 00 000 µS/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 contact 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 all 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.
• Available for wall-mounting and panel-mounting.
• vailable (input /output) : 24/24V, 115/115V, 230/230V.
