  • Page 12: Part 3 - Sensor Installation

    Part 3 – Sensor Installation General The UV/Turbidity sensor may be used either in a flowcell or submerged in a tank or channel. The flowcell used with the system is designed to eliminate ambient light effects and to allow sample pressure to be maintained through the flowcell minimizing air bubble formation that can cause measurement errors.

  • Page 13: Flowcell Mounting

    Part 3 – Sensor Installation Q46UV UV254/Turbidity Monitor Flowcell Mounting Figure 7 provides flowcell dimensions. Note that the flowcell should always be mounted horizontally with the inlet on the bottom and outlet on the top. Select a flowcell location with sufficient clearance below to allow installation of the inlet calibration valve to facilitate adjustment of the system after installation.

    Part 3 – Sensor Installation Q46UV UV254/Turbidity Monitor Submersible Installation The standard UV sensor may also be used for submersion installations. Note that the turbidity measurement may be affected by bright ambient light conditions. Submerged sensors MUST be located in dark areas. Figure 10 below shows a typical submersion mounting using ATI’s 00-1690 submersion mounting kit.

  • Page 17: Part 4 - Electrical Installation

    Part 4 – Electrical Installation General The Q46 is powered in one of two ways, depending on the version purchased. The 12-24 VDC powered analyzer requires a customer supplied DC power supply. The 90-260 VAC version requires line power. Please verify the type of unit before connecting any power. WARNING: Do not connect AC line power to the DC version.
  • Page 18 Part 4 – Electrical Installation Q46UV UV254/Turbidity Monitor WARNING Disconnect line power voltage BEFORE connecting line power wires to Terminal TB7 of the power supply. The power supply accepts only standard three-wire single phase power. The power supply is configured for 115 VAC or 230 VAC operation at the factory at time of order, and the power supply is labeled as such.

    Part 4 – Electrical Installation Q46UV UV254/Turbidity Monitor Relay Connection Three SPDT relays are provided on the power supply board. None of the relay contacts are powered. The user must supply the proper power to the contacts. For applications that require the same switched operating voltage as the Q46 (115 or 230 V), power may be jumped from the power input terminals at TB7.

    Part 4 – Electrical Installation Q46UV UV254/Turbidity Monitor Remote Sensor Wiring Generaly it is best to keep the sensor close to the monitor. However, it is possible to mount the sensor as much as 100 feet from the monitor using a junction box and additional interconnect cable.

  • Page 24: Part 5 - Configuration

    Part 5 – Configuration User Interface The user interface for the Q46 Series instrument consists of a custom display and a membrane keypad. All functions are accessed from this user interface (no internal jumpers, pots, etc.). When power is first applied, you may notice that the display does not come on immediately. This is normal.

  • Page 25: Keys

    Part 5 – Configuration Q46UV UV254/Turbidity Monitor 5.11 Keys All user configurations occur through the use of four membrane keys. These keys are used as follows: MENU/ESC To scroll through the menu section headers or to escape from anywhere in software. The escape sequence allows the user to back out of any changes in a logical manner.

  • Page 40: Part 6 - Calibration

    Part 6 – Calibration UVA/Turbidity Calibration UVA monitors will start to measure aqueous samples as soon as power is applied and sample is flowing through the flow chamber. Calibration of a UVA sensor is normally not required. The UV absorbance curve is stored in the sensor and changes only very slowly. A zero adjustment should be done every 6 months to compensate for small changes in optical components with time.

    Q46UV UV254/Turbidity Monitor Part 6 - Calibration 6.13 Cal Turbidity Zero Adjustment of the turbidity measurement in the UVA/Turbidity sensor requires the use of distill water for zero and a Formazin standard for span. To zero the sensor, proceed as follows. Note that the procedures for turbidity zero and turbidity span are essentially the same as for UVA zero and span adjustments.

  • Page 45: Part 7 - Pid Controller Details

    Part 7 – PID Controller Q46UV UV254/Turbidity Monitor Part 7 – PID Controller Details PID Description PID control, like many other control schemes, is used in chemical control to improve the efficiency of chemical addition or control. By properly tuning the control loop that controls chemical addition, only the amount of chemical that is truly required is added to the system, saving money.
  • Page 46 Part 7 – PID Controller Q46UV UV254/Turbidity Monitor The most notable feature of the algorithm is the fact the proportional gain term affects all components directly (unlike some other algorithms - like the “series” form.) If a pre-existing controller utilizes the same form of the algorithm shown above, it is likely similar settings can for made if the units on the settings are exactly the same.

  • Page 47: Classical Pid Tuning

    Part 7 – PID Controller Q46UV UV254/Turbidity Monitor Classical PID Tuning Unlike many high speed position applications where PID loops are commonly used, the chemical feed application employed by this instrument does not require intense mathematical exercise to determine tuning parameters for the PID. In fact, the risk of instability is far greater with overly tuned PID control schemes.
  • Page 48 Part 7 – PID Controller Q46UV UV254/Turbidity Monitor The easiest process’ to control with closed-loop schemes are generally linear, and symmetrical, in nature. For example, controlling level in tank where the opening of valve for a fixed period of time corresponds linearly to the amount that flows into a tank. Chemical control process’ can be more problematic when the nature of the setpoint value is non-linear relative to the input of chemical added.

  • Page 49: Part 8 - System Maintenance

    Part 8 – System Maintenance General The Q46 UV/Turbidity Monitor will generally provide unattended operation over long periods of time. With proper care, the system should continue to provide measurements indefinitely. For reliable operation, maintenance on the system must be done on a regular schedule. Keep in mind that preventive maintenance on a regular schedule is much less troublesome than emergency maintenance that always seems to come at the wrong time.

  • Page 50: Part 9 - Troubleshooting

    Part 9 – Troubleshooting General The information included in this section is intended to be used in an attempt to quickly resolve an operational problem with the system. During any troubleshooting process, it will save the most time if the operator can first determine if the problem is related to the analyzer, sensor, or some external source.
