3. PG7/9 cable glands (8 pieces) INSTALLATION OF THE PROGRAMMER The PRG11 programmer can be mounted on the frame of the osmosis equipment, or wall installed. It is recommended to choose a dry and ventilated location, avoiding confined spaces that restrict programming, testing and maintenance operations. -
Page 5: Technical Data
250V~ and 3A (resistive) Digital inputs accept voltage free contact, 18V @ 10mA; 3-wire sensors (magnetic or capacitive), using the power of PRG11 (18V), see “Electrical connections” section Conductivity inputs 2 inputs from 2-electrode cell, also including NTC sensor and shielded cable ;... -
Page 6: Typical Installation Diagram
TYPICAL INSTALLATION DIAGRAM The PRG11 programmer is an electronic unit specifically designed for the control of reverse osmosis plants. The reference hydraulic system is shown in the diagram below. A typical installation includes the following components: 1. Solenoid valve for water inlet, NC (EV1) 2. -
Page 7: Operation Outline
Visualizations While in normal operation mode, the display shows the current status of the PRG11 programmer. The top row displays the following sequence: status of the device (standby, production or cleaning), the two conductivity values (COND2 = feed water, COND1 = product water) and the percentage of filter remaining life (if parameter P14 ≠... -
Page 8: Electrical Connections
ELECTRICAL CONNECTIONS Check that the device is not powered and open the terminal block cover to perform the electrical connections. Also refer to the diagram below. Once wiring is completed, tighten the cable glands and close the cover. Clock buffer battery Fuse for 24V~ (F2A) Microprocessor Buzzer... - Page 9 • For STEIEL conductivity cells the pair of wires brown / blue or brown / green is related to the electrodes, while the pair of wires yellow / white or yellow / black is related to the NTC sensor.

Page 10: Date/Time Adjustment
DATE/TIME ADJUSTMENT The PRG11 is equipped with an internal clock that allows to schedule filter cleanings at set times (also see the “Configuration” section). To adjust the clock, proceed as follows: 1. Press the ESC key until the display shows “DATE/TIME SET”... - Page 11 P01 Password This parameter allows to set a protection password (different from zero) to prevent the access to the configuration menu by unauthorized personnel. Warning! If you forget your password, the instrument must be sent back to the factory for a complete reprogramming! P02 Language The display interface of the programmer can show messages in the following languages:...
- Page 12 P15 Filter duration (life) Set this parameter to filter life. In fact, the PRG11 programmer is able to count the working hours of the filter (production with running pump) and compare them with the value set in this parameter. If the operating time exceeds this threshold, the “FILTER LIFE”...

3. The display shows “PRESS. PUMP" and its current configuration (OFF=off, ON=on); at this point you can switch the output through the ACK key 4. Using the [+] and [-] you can check / activate all the outputs of the PRG11 5. Press ESC to exit the output test mode... -
Page 14: Calibration / Customized Configurations
CALIBRATION / CUSTOMIZED CONFIGURATIONS The PRG11 programmer is accurately calibrated and configured at the factory accordingly with the specific installation needs, and normally does not require any intervention by the installer/customer. Any tampering or modification by the customer, not authorized by the manufacturer, will void the warranty, and often cause malfunctioning of the device.
