1. Introduction
Your microprocessor-based controller has been designed to monitor and control the conductivity of your process water. The controller energizes two relay outputs based on a bleed and feed mode of operation.
- When the conductivity measurement goes above the user defined set point, (2) two relays are
energized until the conductivity goes below the set point minus the fixed differential value.
The feed relay will also de-energize when the user programmable feed limit time is reached.
- Optional - The feed control relay will energize based on a percentage of a 10 minute feed cycle.
Your controller may or may not have the following optional configurations:
Pigtails (pre-wired)
The controller is pre-wired with a power cord and drop down receptacles for plugging in control devices such as a solenoid valve or a metering pump.
Flow Switch
The controller is supplied with a flow switch that is installed into the process flow line to signal the controller that your system has water flowing. When there is a no flow state, the controller will not energize the outputs.
2. Installation
2.1 Controller Location
Select a mounting location convenient to grounded electrical and plumbing connections. Mount the controller on a wall or other vertical surface with adequate lighting at a comfortable level. Remove the four screws that retain the front panel and remove it, mounting passages are located in each of the four corners in the back of the enclosure (See page 15). Installation should comply with all national, state and local codes.
Avoid locations where the controller would be subjected to extreme cold or heat {less than 0°F (-17,8°C) or greater than 122°F (50°C)}, direct sunlight, vibration, vapors, liquid spills or EMI (electromagnetic interference; e.g., strong radio transmission and electric motors). The controller could be damaged and void the warranty!
2.2 Sensor Installation
The controller is supplied with a temperature compensated conductivity sensor (probe). Install the sensor at some point in your process where chemical and water are thoroughly mixed. If the sensor is to be placed in a tank or sump, ensure that it is installed so that the black shrink-wrapped part of the probe cable is not submerged. The probe should also be located in a position where adequate flow is going across and through the probe.

-
breaker, marked as the unit’s disconnecting device
If your controller is provided with a flow switch, install the flow switch so that flow enters into the bottom of the provided flow switch tee, and out of the side of the tee. The flow switch must always be installed in a vertical position so that the sensor wire is coming out of the top, and the internal (red) flow shuttle is able to rise when there is flow and drop when there is not flow. The flow switch is activated when 1 GPM (3.8 LPM) is going through it, and is deactivated when the flow drops below 1 GPM (3.8 LPM).
3. Electrical Wiring1
The controller electronic circuitry is fuse protected. Use of a surge protector and Ground Fault Circuit Interrupter (GFCI) are strongly recommended!
Controller must be wired in accordance with all applicable electrical codes.
Input power must be 120 or 220VAC Single Phase.
Trained service personnel are required for all electrical connections. This product does not contain operator serviceable parts.
same voltage as the input voltage to the product. (e. g. 120VAC MicroTrac controllers support 120VAC relay attached devices exclusively and 220VAC MicroTrac controller support 220VAC relay attached devices exclusively.) Do not apply power until this condition is verified.
Input power cord must be disconnected from power source prior to opening the product’s enclosure and making any electrical connections.
The controller should be connected to a dedicated power branch (i.e., its own wiring, circuit breaker, etc.). For best results, the ground should be independent (true earth) not shared.
should be included in the installation. It should be in close proximity to the unit and easily reached by the user.

Pre-wired controllers are supplied with 6 ft (1,8 m), 18 AWG (1,2 mm2) 3-wire grounded power cords and clearly marked 18 AWG (1,2 mm2) 3-wire grounded receptacle cords for all controlled line voltage outputs.
Controllers that are to use electrical conduit are factory pre-drilled with easily accessible connections for hard wiring of input and output power connections. Use only 16 AWG (1,5 mm2) or 18 AWG (1,2 mm2) wire for conduit power and load connections.
3.1 Electrical Connections2
If your controller was not ordered as a pre-wired controller, hard wiring will be required. With the main power disconnected from the controller, loosen the four screws that retain the front panel of the controller and remove the front panel. There are five terminal block connectors inside the controller that will need to be wired.
Supply power
The controllers supply power is identified on the main PC board as location PL3 (refer to Fig. 3 on page 8). There are three connections identified on the board for this terminal block, HOT (LINE), RTN (return or Neutral), and Ground.
Flow and Water Meter Inputs
These two inputs are located on connector PL2. This is where the two wires from the flow switch or water meter will connect. Polarity on this terminal block is not important.
If your controller is not equipped with a flow switch, there should be a jumper wire installed across PL2. (See Fig.3)
Dose/Feed (metering pump)
This control output is identified on the controller PC board as location PL4. The terminal block connections for PL4 are HOT (LINE), RTN (return or Neutral), and Ground.
This control output can drive pumping equipment based on the bleed and feed with limit timer mode. This output energizes when the programmed conductivity set point is exceeded. This output will de-energize when the conductivity reading falls below the set point minus the fixed set point differential (-5% of set point) or when the programmed feed limit time is exceeded.
Optional - This output energizes for a programmed percentage of a fixed 10 minute feed cycle.
The controller is fused at 5 amps maximum. Both output devices combined can not exceed 5 amps of current.

Feed Percent
+ Time
Percentage – Set this value to a percentage of the prior Bleed cycle the Feed output should energize. Example: Percent=25, Bleed cycle took 14 minutes, the Feed output would energize for 25% of 14 minutes, or 3.5 minutes. Range = 0-100. Time – Optional limit timer. Set this value to the maximum amount of time the Feed output should energize before going into an alarm condition. Once this timer expires the Feed output will de-energize. Range = 0-08:00, hh:mm. The time value is adjusted in 15 minute increments.
Percent Timer – This control mode causes the Feed output to energize based on a
percentage of a fixed time cycle. The cycle time is base on a fixed 10-minute cycle. Once the 10-minute cycle completes the cycle will be restarted again.

4.3.2 Conductivity Set Point
Set this value to the highest conductivity point the controller will allow before a bleed and feed cycle begins. When the system conductivity reaches this set point the bleed and feed control outputs will energize. When the system conductivity falls to the conductivity set point minus 5% the bleed and feed cycle will terminate and the control outputs will de-energize. The Conductivity Set Point can be changed with the [Up]/[Down] buttons once in programming mode. The maximum setting is 9999 uS/cm. To save the set point, press the Mode [m] button.
The set point differential is fixed at 5% below the set point. For example, if the set point is set to 1000uS/cm the bleed and feed outputs will energize at 1000uS/cm and de-energize at 950uS/cm.
4.4 Alarm Conditions
Flow Alarm
With a loss of flow the two (red) LED’s will flash and the display will read “Err Flo.” The outputs will de-energize. This alarm will reset automatically with the resumption of flow.
Feed Limit Timer Alarm
When the Feed Limit time is exceeded the two red LED’s and the blue LED will flash and the display will read “Err Lit” and the Feed relay will de-energize. This alarm is reset by: pressing the M (Mode) button, a flow cycle, or conductivity reaching the set point and differential.
Bleed Limit Timer Alarm
When the Bleed Limit time is exceeded the two red LED’s and the green LED will flash and the display will read “Err Lit”. This alarm is reset by: pressing the M (Mode) button, a flow cycle, or conductivity reaching the set point and differential. This will not de-energize the bleed relay, only reset the timer.
Bleed and Feed Limit Timer Alarm
When the Bleed and Feed Limit time is exceeded, all the LED’s will flash and the display will read “Err Lit”. This alarm is reset by pressing the M (Mode) button, a flow cycle, or conductivity reaching the set point and differential.
Bleed Limit Alarms: will not de-energize the Bleed relay.
Conductivity Over Range Alarm – (Rising Set Point)
If the conductivity is over 9,999uS/cm, all the LED’s will flash and the display will read “Err 9,999” and the Bleed relay will remain on. This alarm is reset by pressing the M (Mode) button once the conductivity is within range.
72-910-02 REV. P
13
Page 14
Both Limit Timers will reset if the conductivity reading changes to above or below the set point and differential.
5. Sensor Calibration
The controller is factory calibrated and requires no user adjustments. Some deviation in the reading may be expected when compared to a hand-held tester. However, if you wish to perform a calibration, follow this procedure:
1. Place the probe in the process that it will normally be installed in and allow flow across the probe for approximately 15 minutes. This will allow the probe temperature to equalize.
2. While the “uS” LED is steady press and hold the “m” mode button for five seconds until the controller flashes “Cal”. Release the “m” button.
1. The controller will now display the actual conductivity reading from the probe. Use the up and down buttons to change the reading until it matches your hand-held’s reading. If you press and hold the up or down buttons, the displayed value will change very quickly.
4. When finished press the “m” button once.
IMPORTANT! For optimum performance, make sure that the system conductivity is near the set point that you intend to operate the system.
The calibration process is now complete.
