I. Introduction

NANO XL microprocessor based controllers are designed to provide a wide range of control functions for recirculating water treatment systems. The controller is programmed through a front panel keypad and can be configured to provide a customized control system for your application. Your particular unit’s functions can be determined by comparing the units model number to the Model Numbering table listed below.

Model Numbering NanoTron units have several base system control functions and unit optional features. Your unit may be supplied with one or more of the features described in this manual. To determine what features apply to your unit check the model number label located on the controller enclosure.

Base Control Function B2 – Boiler Conductivity and 3 Feed Timers C – Tower Conductivity and 3 Feed Timers F4 – Four Selectable Feed Timers

Whole Unit Optional Features A – Conduit Connections A3 – Conduit with CE E – Flow Switch

II. Description
NanoTron units are designed to automate conductivity control and / or the addition of various chemicals or activate other devices via a relay output. Each relay can have its activation function selected from available analog inputs, timers, alarms or utility.
NANOXL-C and NANOXL-B2 units include: · Two totalizing water meter inputs that can be configured for contacting head or hall effect meter inputs. · Three digital inputs that can be set to disable a relay output. · Four mechanical relay outputs with normally open and normally closed contacts that can be configured
for powered or dry contact relay operation (see page 4 diagram).
Conductivity Control (C & B) – Conductivity monitoring and control of Total Dissolved Solids (TDS) in a recirculating water systems in terms of electrical conductivity measured in MicroSiemens/cm. The conductivity scale can be selected from three ranges (low, mid and high) in the Configure menu (see page 12). Selectable feed timers are also included (see timer description below).
Feed Timer – Three selectable timers that can be individually programmed as one of the following types:
1. Pulse Timer ­ Accepts dry contact pulses from a water meter (supplied separately). It can accumulate 1-9999 pulses to activate the timer to run from 0-99 minutes, 59 seconds in minutes and seconds. Timer will store up to 5 additional activations during an individual run time.
2. Recycle Timer ­ Provides a user defined “off” cycle in HH:MM and a user defined “on” cycle in MM:SS that is repeated constantly.
3. 28-Day Timer – 28-day feed timers, typically used for biocide feed are based on a 28-day cycle with two independent programmable feed cycles allowing for feed on selectable days and weeks.
4. Post Bleed Timer – The relay is activated after a bleed cycle and runs for the set percentage of that bleed cycle.
5. With Bleed Timer – Activates the relay output simultaneously with the bleed and limits the amount of time the relay output will be on during the bleed cycle.
6. Utility – Relay always on 7. Alarm – Relay on with alarms

III. Installation
Electrical Wiring The controller has an internal regulated power supply that will operate in the range of approximately 100 to 240 VAC on the incoming wiring. Output relay(s) are protected with a replaceable fuse. Relay output voltage will equal the incoming line voltage.
Prewired units are supplied with a 16 AWG cable with a 3-wire grounded USA 120 volt plug for incoming power and 18 AWG 3-wire grounded receptacle cords for all control relay outputs. Conduit units are supplied with liquid tights and adaptors for easy hard wiring to supplied connector.
! CAUTION !
1. There are live circuits inside the controller even when the power switch on the front panel is in the OFF position. Never open the front panel without first disconnecting power from the outlet. Prewired controllers are supplied with an 8 foot, 18 AWG power cord with USA style plug. A #1 Phillips driver is required to open the front panel.
2. Low voltage signal wires (probes, flow switch, water meter, etc.) should never be run in conduit with high voltage (like 115VAC) wires.
3. Never attempt to land connections to the controller without first disconnecting power from the outlet. 4. Do not block access to disconnect power during mounting and installation. 5. The controller should be connected to its own isolated circuit breaker, and for best
results, the ground should be a true earth ground, not shared. Any attempt to bypass the grounding will compromise the safety of users and property. 6. The electrical installation of the controller must be performed by trained personnel only and conform to all applicable National, State and Local codes. 7. Operation of this product in a manner not specified by the manufacturer may result in damage to equipment or persons. 8. Avoid mounting in locations that expose the controller to direct sunlight, vapors, vibration, liquid spills or extreme temperatures; less than 0°F (-17.8°C) or greater than 120°F (50°C). EMI(electromagnetic interference) from radio transmissions and electric motors can also cause damage or interference and should be avoided.
NOTES: 1. Liquid tight fittings and some labeled signal leads are provided for signal (low voltage) connections,
such as water meter inputs. 2. Hall effect meters that require +12 VDC must use an external power supply (TFS-PWR). 3. Optional 4-20mA ouput is produced with 12 VDC on the loop. Do not connect output to devices
that are trying to power the loop.
Mounting Instructions
Select a mounting location that provides the operator easy access to the unit and a clear view of the controls through the cover of the controller. The location should be convenient to grounded electrical connections, the needed sample line plumbing and is on a stable vertical surface.

Electrode Installation
Controllers may come configured for various circulating water systems. Listed below are instructions for cooling tower and boiler typical installations. Your specific installation requirements may differ but should conform to these instructions as much as possible for proper operation.

A. Cooling Tower
The standard probe(s) and/or flow assembly for cooling tower installations is constructed of schedule 80 PVC and supplied with 3/4″ slip fittings for installing into a sample line. To insure proper operation the sample line must have a flow rate of 3-10 gpm. Inlet pressure must be higher than outlet pressure in order for water to flow past the electrode(s) to achieve the required rate. The probes are temperature compensated for increased accuracy.

NOTES:

1. Install an isolation valve on either side of the flow

assembly so electrodes can be easily isolated for

removal and cleaning.

2. A line strainer is recommended upstream from

the probes to protect against fouling and damage.

3. Systems with a flow switch require 2-3 gpm flow

rate to operate outputs. !
WARNINGS:

PE-NUT

1. Electrodes are O-ring sealed, which if

damaged will cause a leak.

Do not allow pH sensor tips to dry out, E-30-PH

damage will occur.

3. Do not exceed a water temperature range

of 32°F to 140°F. 4. Do not exceed a maximum pressure of

MW-T-3

150 psi.

B. Boiler

Standard boiler electrodes have a MNPT stainless steel bushing and are supplied with a FNPT cross designed for mounting in the skimmer (surface) blowdown line. Sampling of the boiler’s water can be achieved using one of two typical plumbing configurations (continuous sampling or timed and/or hold sampling). For a successful installation, it is critical to observe the recommended distances and pipe
sizes provided in the installation drawings.

For best results, the electrode cross should be mounted in a 1″skimmer blowdown line within 4′ of the boiler. Smaller line sizes and greater distances may affect the response time and accuracy of the electrode. A flow- throttling device down stream from the probe (within 24 inches) is required to ensure that the electrode is exposed to water and not steam. Properly installed and adjusted, this device will prevent
flashing in the electrode chamber.

NOTES: 1.
2.
3.

Install a fully ported type valve between the electrode and the boiler. This allows the electrode to be isolated for removal and cleaning.
A flushing line and 1/4 turn type ball valve should be installed in the bottom of the cross to periodically “flush” sediment from the electrode chamber. Make sure the alignment arrows on the probe end up parallel to the flow for best performance.

! WARNINGS:
1. The probe must be fully immersed in the system water to read correctly. Steam flashing will result in incorrect readings.
2. Do not exceed a maximum water temperature of 436°F (224°C) 3. Do not exceed a maximum pressure of 350 psi (24.1 bar) 4. A throttling device must be installed down stream from the elecrode.

V. System Operation Overview

Description of Menus

NANOXL controllers have two modes of operation, Run and Menu. All menus are circular. Pressing the DOWN key will display the next line of information on the display.

Run –

This mode is for normal operation. In the Run mode, the display will read system values. If an alarm is present, the display flashes with the alarm status.

The Run menu will display values such as day, time, date and other values depending upon the features present on the unit. The unit will automatically return to the Run mode if no keys are pressed for three minutes.

Menu –

This mode is used to make adjustments to settings and readings on the controller. To access
the Menu mode from the run screen, press the Menu key. Use the up or down arrow to scroll through the various menus. When you want to access a specific menu, press the Enter key. Once you have entered a sub-menu you will be able to step through that menu’s options with the up or down arrow key.

Conductivity Sampling Methods
A. Continuous – Typical for most tower applications. The controller is constantly reading the sensor and activating the bleed relay based on readings relationship to the set point, set point direction and differential. Example: A rising set point of 1500 and differential of 50 the bleed relay would activate when the conductivity rises above 1500 and stays on until the reading drops to 1450.
B. Timed Sampling – A sample timer allows the conductivity to be sampled at periodic intervals. Sample intervals are adjustable from 1 minute to 9 hours, 59 min. Sample duration (on-time) is adjustable from 1 second to 99 minutes, 59 seconds. If the reading is below the set point by the differential amount the bleed relay will be turned off at the end of the sample duration and the sample interval countdown reinitiated. If the reading is above the set point at the end of the sample method the bleed relay stays on until the reading drops by the differential amount.
C. Sample and Hold – Also uses a sample timer for periodic sampling intervals. The unit will sample for its duration then hold the blowdown valve closed for a settable period (hold time). The conductivity is checked at the end of the hold period, if additional blowdown is required the blowdown valve is held open for a preset amount of time (blowdown time). Then sample cycle is repeated until the reading is below the set point at the end of a hold cycle and the sample interval countdown reinitiated.
Note: Timed Sampling and Sample and Hold are typically used for boiler applications but Timed sampling can also be used on small towers. On these tower applications the probe is installed in the bleed line before the bleed valve.
Calibration Overview
The NanoTron controllers update the conductivity reading every two seconds with a running average. Nanotron controller’s conductivity scale should be selected so that the conductivity setpoint is as close as possible to the middle of the scale. (See page 12 menu for setting scale).
Note: If a controller is using Timed Sampling or Sampling and Hold methods of control the conductivity reading shown in the RUN mode may not be a current reading. The controller will hold and display the conductivity value seen at the end of the last sample or hold duration. To see a current reading force on the bleed relay with either the Force button or via the Calibration menu.
A. Continuous – Calibrating continuous sampling units can be done at any time with the probe in a steady stream of water with no air or steam present.
B. Timed Sampling – While in the calibration menu there is a selection to force on the bleed relay. It will force it into the sample period. After 1-2 minutes verify that the reading is stable then enter the desired calibration value.
C. Sample and Hold – While in the calibration menu there is a selection to force on the bleed relay. It will force the unit into its sample and hold periods and calibration should be done during the hold after a fresh sample.
Notes: 1. If steam is flashing on boiler probes a stable reading will not be maintained and the controller will not track. 2. Recalibration is required if the scale is changed in the Configure menu.

VI. Maintenance
The only required maintenance for normal uninterrupted operation of your controller is cleaning of the electrode(s). After initial start up, it is a good idea to clean the electrode frequently until a schedule based on need has been developed. Since each application is unique, it is difficult to estimate the required frequency of cleaning. The first cleaning should take place after about one week of the system being on line.
To determine the required cleaning frequency, record the reading on the controller before the electrode is removed for cleaning. After cleaning, record the new reading. If a change is observed in the two readings, the electrode was dirty. The more significant the change, the dirtier the electrode. If no change occurs, cleaning needs to be done less often.
Conductivity Electrode Cleaning Procedure
1. Record the current conductivity reading. 2. Turn off water flow through the electrode loop, bleed pressure from the line and remove
electrode. 3. Use a clean cloth and a mild cleaning solution to remove loose dirt etc., from the flat
surface of the electrode. 4. If the electrode has deposits such as scale attached to the electrode surface a more
aggressive cleaning approach will be needed. There are several ways to do this, the preferred method being the one that is easiest for the user. a. Use a mild acid solution to dissolve deposits. b. Lay a piece of sandpaper (200 grit or finer) on a flat surface such as a bench
top. “Sand” electrode to remove stubborn deposits. (Do not wipe surface with your finger.) Oil from your skin will foul carbon tips. 5. Reinstall the electrode in the system. After the reading stabilizes, calibrate the unit to a reliable test reading.
Many times an electrode can appear to be clean, but the unit still cannot be calibrated. If this is the case, use one of the more aggressive electrode cleaning procedures listed in step 4 above. Recheck the calibration after completion of this procedure. If no change was observed in the reading, replace the electrode. If a change occurred but the unit still will not calibrate, repeat procedure as many times as necessary.

VII. Troubleshooting
The Advantage NanoTron controller is designed for many years of trouble free operation. Should a problem occur, refer to the following chart to help identify the problem. If replacement is required, follow the procedures listed in the Warranty and Factory Service portion of this manual.
