  • Page 4: Part 1 - Introduction

    Part 1 - Introduction General The Model Q46/85 is an on-line monitoring system designed for the continuous measurement of Peracetic Acid (PAA) concentration in solution. The full scale operating range of the system may be selected by the user for 0-20.00 ppm, 0-200.0 ppm, or 0-2000 ppm, and the sensing system will operate on water streams with temperatures ranging from 0 to 50°C.

  • Page 5: Standard System

    Q46H/85 PAA System Part 2 – Analyzer Mounting Standard System The standard model Q46/85 system includes three main components, the Q46 analyzer, a constant head flow cell, and a PAA sensor. A low-volume flowcell is also available for applications where sample flowrate and pressure can be carefully controlled. Figure 1 shows a typical installation including the optional pH sensor.

  • Page 6: Figure 2 - Monitorings

    Q46H/85 PAA System Part 2 – Analyzer Mounting Figure 2 below shows the same standard flowcell assembly and PAA 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.

  • Page 7: Figure 3 - Sealed Flowcell

    Q46H/85 PAA System Part 2 – Analyzer Mounting Figure 3 below shows an installation using a (00-1522) sealed flowcell for the PAA 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 (03-0371) flow control assembly when using sealed flowcells.

    Q46H/85 PAA 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 15: 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 PAA 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 16: Sealed Flowcell

    Q46H/85 PAA System Part 3 – Sensor/Flowcell Mounting 3.3 Sealed Flowcell Applications where the sample inlet flow is well controlled can use a simpler sealed flowcell. Using this flowcell requires that flow be controlled externally to about 400 cc/min. Variable flow rate or variable pressure will cause unstable readings in this flowcell.

  • Page 18: Submersion Mounting

    Q46H/85 PAA System 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. PAA 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 19: 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 a DC powered unit.

  • Page 20: Figure 13 - Line Powerc

    Q46H/85 PAA System Part 4 – Electrical Installation 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. AC power supplies are configured for 90-260 VAC operation at the factory at time of order, and the power supply is labeled as such.

  • Page 21: Figure 14 - Optional Relay

    Q46H/85 PAA System Part 4 – Electrical Installation 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 jumpered from the power input terminals at TB7.

    Q46H/85 PAA System Part 4 – Electrical Installation TB2, is used to connect to the optional 3-relay card (Figures 14) OR the optional third analog outputOut#3, Figure 15. The Q46 can be configured for only one of these optional features, and the hardware for either option must be factory installed.

  • Page 23: Direct Sensor Connection

    Q46H/85 PAA 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 24: Sensor Wiring

    Q46H/85 PAA 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.

    Part 9 – System Maintenance General The Q46/85 PAA System 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.
