Typical Configuration’

Controller Detail: Terminal Board, TB-1 (See Fig. 1 for schematic)

Ntinye nyocha omume

Install the Conductivity Probe in the “Run” of a Tee or equivalent location. Orient the probe so that air can not become trapped in the area near the probe.

Nwụnye

Drill the enclosure as needed and install liquidtight fittings for the wiring.
IHE: The Controller can be ordered pre-drilled or with fittings installed, or with fittings and wiring installed. Contact Nelsen Corporation for details.
Mount the enclosure in the desired location on the RO system.

Bring the wires from the peripheral devices into the enclosure and connect them to the appropriate terminals. (See Figure 1, Figure 3 and Figure 4.)
Install the conductivity cell in the permeate line. (See Figure 5 for conductivity cell installation instructions.)

Connect the conductivity cell to the terminals on the CPU Board. (See Figure 3)
Provide power to the RO system.

Press the System On/Off switch to turn the system ON.
Program Mode 2 is default (See Table 2) which is a general purpose setting, without a flush valve.
IHE: The Program Settings can be
ahaziri to suit the specific needs of an OEM and pre-programmed at the factory with your settings. Contact Nelsen Corporation for details.

Make any other changes you want to the settings. Press System On/Off to save your changes.
The controller is now ready for service.
IHE: YOU MUST REMOVE THE JUMPER
WIRE FROM E23 TO E24 if using a single point High Level RO water shut off float switch control and connect the float switch wires to terminals E23 and E24 (See Fig. 4).
If you are using a piggyback float plug leave the jumper wire in place.

Controller Programming: Accessing the Hidden Menus

System Start-up w/Permeate Flush

For systems equipped with a Permeate Flush, you must follow the procedure below for proper system startup. When there is no Permeate Water in the tank the RO will not start.

With the system on, Press and Hold the Up and Down Arrows
With the Up and Down Arrows depressed, Press the System On/Off button. This will switch to the Hidden Menus as shown above.

If not already on the RO Presets Program, Press the Up or Down Arrows until you reach this screen.
Once on the RO Presets Program Screen, Press Manual to Edit this Screen.
Press the Up or Down Arrow to change to Program 2
Once on Program 2, Press Manual to Exit the screen.
Press System On/Off to save the changes and return to the Home Page.

Once your Permeate Tank has filled enough to do a proper permeate flush, follow the steps again changing from Program 2 back to Program 3.

Table 2 – Controller Programming: ROC2HE Program Selections

The controller has 4 separate, user-selectable sets of settings for configuring the RO. The factory default settings are shown below. The settings are identical except for variations in the flush behavior.

If RO Not Working and Display Shows “Tank Full” or “Tank Full Draw Down”

If using a single point high level float switch, the jumper in the wiring instructions must be installed. This needs to be checked to make sure it is not loose and or disconnected, which would cause a failure and one of the displays above. ie. Remove jumper and reinstall, making sure of a good connection. Re-check display and operation.
Check the switch in the tank to make sure it is operating correctly. Check the switch with a multi-meter for correct “on-off” operation. Replace switch or level control if faulty.
If someone connected 110v to the terminal strip connection for the high level shut off, they could have fried the “opto-isolator”.

Also, if there were major lightning strikes and power outages with surges, it is possible that you may have had a power surge that sent electric current to the dry contacts and possibly fried the “opto-isolator”.
This will prevent the system from turning on, and the display will show Tank Full messages.
If the jumper is verified to be in place with good connections, and if the high level cut off switch in the storage tank is verified to be operational, then the board might need to be replaced due to number 3 or 4.
