REVERSE OSMOSIS CONTROLLER - OS3050 / OS3051

Reverse Osmosis Controllers - OS3050 / 3051
OS3050 / 3051 USER MANUAL

The unit type OS3050 (OS3051) is universal applicable for automatic monitoring and control of reverse osmosis plants. There are five possible stages : “Stand by”, “Production”, “Rinse after production”, “Rinse during standby” and “Maintenance. This unit can monitor conductivity, temperature (optional) and several inputs e.g. level switches, low pressure switch, motor security switch, etc. 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
