  • Page 4: Part 1 - Introduction

    Part 1 - Introduction General The Model Q46H/63 is a versatile on-line monitoring system designed for the continuous measurement of combined chlorine in solution. The full scale operating range of the system is user selectable for 0-200.0 ppb, 0-2.000 ppm, 0-20.00 PPM, or 0-200.0 ppm, and the sensing system will operate on water streams with temperatures from -5 to 55°C.

  • Page 5: Standard System

    Q46H/63 Combined Chlorine System Part 1 - Introduction Standard System The standard model Q46H/63 system includes three main components, the Q46H analyzer, a constant head flow cell, and a combined chlorine sensor. A sealed flowcell is also available for applications where sample flow rate and pressure can be carefully controlled. Figure 1 shows a typical installation including the optional 07-0096 pH sensor.

  • Page 6: Figure 2 - Chlorine System W

    Q46H/63 Combined Chlorine System Part 1 - Introduction Figure 2 below shows the same standard flowcell assembly and chlorine sensor along with the conventional type pH sensor. A special adapter is required to hold the pH sensor in its proper location in the flowcell inlet chamber.

    Q46H/63 Combined Chlorine System Part 1 - Introduction Figure 3 below shows an installation using a 00-1522 sealed flowcell for the chlorine sensor and a 00-1527 sealed flowcell for the pH sensor. This type of installation requires careful flow control. We recommend the use of our 03-0372 flow control assembly when using sealed flowcells.

  • Page 12: Part 2 - Analyzer Mounting

    Part 2 – Analyzer Mounting General All Q46 Series instruments offer maximum mounting flexibility. A bracket is included with each unit that allows mounting to walls or pipes. In all cases, choose a location that is readily accessible for calibrations. Also consider that it may be necessary to utilize a location where solutions can be used during the calibration process.

  • Page 13: Wall Or Pipe Mount

    Q46H/63 Combined Chlorine System Part 2 – Analyzer Mounting Wall or Pipe Mount A PVC mounting bracket with attachment screws is supplied with each analyzer (see Figure 5 for dimensions). The multi-purpose bracket is attached to the rear of the enclosure using the four flat head screws.

    Q46H/63 Combined Chlorine System Part 2 – Analyzer Mounting Panel Mounting Panel mounting uses the panel mounting flange molded into the rear section of the enclosure. Figure 8 provides dimensions for the panel cutout required for mounting. The panel mounting bracket kit must be ordered separately (part number 05-0094). This kit contains a metal retainer bracket that attaches to the rear of the enclosure, 4 screws for attachment of this bracket, and a sealing gasket to insure that the panel mounted monitor provides a water tight seal when mounted to a panel.

  • Page 16: Part 3 - Sensor/Flowcell Mounting

    Part 3 – Sensor/Flowcell Mounting General Select a location within the maximum sensor cable length for mounting of the sensor flow cell. Constant-Head Flowcell Chlorine sensors are best used in a constant-head overflow chamber because variations in sample flow rate and pressure can cause unstable readings. When monitoring low concentrations (below 0.5 PPM), this method should always be used.

  • Page 17: Sealed Flowcell

    Q45H/63 Chlorine Manual Part 3 – Sensor/Flowcell Mounting Once mounted, inlet and drain connections must be made. The flow cell contains a ⅛" MNPT inlet connection and a ⅜" MNPT drain connection. Hose barbs for the inlet and drain connections are supplied with the flow cell for use with flexible tubing.

    Q45H/63 Chlorine Manual Part 3 – Sensor/Flowcell Mounting Submersion Mounting Some applications are much easier done using the submersible sensor. This method can sometimes be used where flow is reasonably constant, and hydraulic head does not vary appreciably. Chlorine sensors can never be used in completely stagnant conditions. A flow velocity of at least 0.3 feet per second is normally required for measurement.

  • Page 20: 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 21: Power Connection

    Q46H/63 Combined Chlorine System Part 4 – Electrical Installation Power Connection Verify the AC power supply requirement before installing. Also verify that power is fully disconnected before attempting to wire. AC powered Q46 systems are supplied with 5 cable gland fittings. Connect HOT, NEUTRAL, and GROUND to the matching designations on terminal strip TB7.

  • Page 22: Figure 13 - Line Powerc

    Q46H/63 Combined Chlorine System Part 4 – Electrical Installation Figure 13 - Line Power Connection The power strip, TB7, allows up to 12 AWG wire. A wire gauge of 16 AWG is recommended to allow for an easy pass-through into the ½” NPT ports when wiring. O&M Manual Rev-K (11/18)

  • Page 23: Figure 14 - Optional Relayb

    Q46H/63 Combined Chlorine System Part 4 – Electrical Installation 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 jumpered from the power input terminals at TB7.

  • Page 24: Figure 15 - Optional Relayb

    Q46H/63 Combined Chlorine System Part 4 – Electrical Installation is used to connect to the optional 3-relay card (Figure 15) OR the optional third analog output Out#3, (Figure 16). The Q46 can be configured for only one of these optional features, and the hardware for either option must be factory installed.

  • Page 25: Direct Sensor Connection

    Q46H/63 Combined Chlorine System Part 4 – Electrical Installation Direct Sensor Connection The sensor cable can be routed into the enclosure through one of cord-grips supplied with the unit. Routing sensor wiring through conduit is only recommended if a junction box is to be used. Some loose cable is needed near the installation point so that the sensor can be inserted and removed easily from the flowcell.

  • Page 26: Sensor Wiring

    Q46H/63 Combined Chlorine System Part 4 – Electrical Installation Sensor Wiring The sensor cable can be quickly connected to the Q46 terminal strip by matching the wire colors on the cable to the color designations on the label in the monitor. A junction box is also available to provide a break point for long sensor cable runs.

  • Page 58: Part 8 - Pid Controller Details

    Part 8 – PID Controller Details PID Description PID control, like many other control schemes, are 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 59 Q46H/63 Combined Chlorine System Part 8 – PID Controller 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 60: Classical Pid Tuning

    Q46H/63 Combined Chlorine System Part 8 – PID Controller 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 61 Q46H/63 Combined Chlorine System Part 8 – PID Controller The easiest processes 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.
