Sensor mounting options include submersion, submersion with Auto-Clean holder, 1 ½” flow tee, or flowcell. If possible, the flowcell or flow tee should be used if expected suspended solids levels are always below 10 mg/l.

  • Page 13: Part 3 - Sensor Installation

    Part 3 – Sensor Installation General The majority of suspended solids applications use a submersible sensor mounted on a pipe and submerged in aeration tanks, effluent channels, or other open tanks. For monitoring very low suspended solids levels, it is often better to use a flowcell or flow tee for measurement, which means the sample must be pumped to the measuring point.

  • 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 the DC version.
  • Page 20 Part 4 – Electrical Installation Q46/88 Suspended Solids Monitor WARNING Disconnect line power voltage BEFORE connecting line power wires to Terminal TB5 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.

  • Page 21: Relay Connection

    Part 4 – Electrical Installation Q46/88 Suspended Solids 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.

  • Page 22: Optional Output/Relay Connection

    Part 4 – Electrical Installation Q46/88 Suspended Solids Monitor Optional Output/Relay Connection TB2 is used to connect the optional 3-relay card (Figure 154) OR the optional third analog output Out#3, (Figure 15). The Q46 can be configured for only one of these features, and the hardware for either option must be factory installed.

  • Page 23: Direct Sensor Wiring

    Part 4 – Electrical Installation Q46/88 Suspended Solids Monitor Direct Sensor Wiring Sensor connections are made to a terminal block mounted on the front section of the monitor. 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.

  • Page 24: Remote Sensor Wiring

    Part 4 – Electrical Installation Q46/88 Suspended Solids Monitor Remote Sensor Wiring Generally 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 25: 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.

    4. Once the zero adjustment is complete, remove the filter from the incoming sample line. 6.12 Cal Span Calibration of a Q46/88 suspended solids monitor is normally done by adjusting the displayed value to a lab measurement. Lab measurements of suspended solids take quite a long time so often an estimated value is used.

  • Page 44: External Light Function

    This is possible when sensors are submerged in flowing streams outdoors in bright sunlight. While it is not normally an issue, the Q46/88 contains a sensor diagnostic feature that measures the amount of ambient light and can provide an alarm in the event that ambient light levels are too high for reliable operation.

  • Page 45: Part 7 - System Maintenance

    Part 7 – System Maintenance General The Q46/88 Suspended Solids 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.

  • Page 46: Part 8 - Troubleshooting

    Part 8 – 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.

  • Page 47: Analyzer Tests

    Q46/88 Suspended Solids Monitor Part 8 - Troubleshooting Check for ground loops. Although the sensor is electrically isolated from the process water, high frequency sources of electrical noise may still cause erratic behavior in extreme conditions. If readings are very erratic after wiring has been checked, check for a possible AC ground loop by temporarily placing the sensor into a bucket of water.

    Q46/88 Suspended Solids Monitor Part 8 - Troubleshooting If analyzer does power up with a display, use the “Simulate” feature to check operation of the analog outputs (and relays contacts with a DVM.) Check sensor power circuits. With a DVM, verify between -4.5 and -5.5 VDC from sensor connection terminals WHITE (+) to BLACK (-).

    Part 9 – PID Controller Q46/88 Suspended Solids Monitor Part 9 – 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 51 Part 7 – PID Controller Q46/88 Suspended Solids 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 52: Classical Pid Tuning

    Part 7 – PID Controller Q46/88 Suspended Solids 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 53 Part 7 – PID Controller Q46/88 Suspended Solids 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.
