    2. Overview The HydroAct 4 is a compact electronic communication and control system. It is designed for use with many different measuring sensors. Any use other than the one described here compromises the safety of persons and the entire measuring system and is, therefore, not permitted. The manufacturer is not liable for damage caused by improper or non-designated use.

  • Page 39 3.1 PC6 Particle Counter 3.1.3.3 Mounting The total space needed to mount the PC6 Particle Counter sensor is an area 533mm (21 in.) wide and 1016mm (40 in.) tall. The PC6 Particle Counter should be permanently mounted to a flat, vertical surface, such as a wall or support column, in an upright position using the 4 mounting holes located on the enclosure.
  • Page 40 Chapter 3. Sensors Important Note on Weir Installation 1. Make sure the clear horizontal pipe at the top of Weir is higher than the top of the PC6 Particle Counter by 254mm to 305mm (10 - 12 in.). This ensures flow will start reliably through the sensor. If the Weir is mounted too low, the flow may not re-start reliably through the sensor if flow was ever lost for any reason.

    With water flowing through the sensor, a check should be performed to make sure the PC6 Particle Counter sensor does not have a cell condition alarm reporting on the HydroAct 4. If there is an alarm, try cleaning the sensor as detailed in section 3.1.6.1. Contact your supplier for assistance if the cell condition alarm does not clear after cleaning.

    Chapter 3. Sensors 3.1.4.3 Setting proper flow rate Since all particle count data must be based on a sample volume, flow control is crucial for accurate and repeatable performance. The simplest and most effective way to achieve constant flow is to utilize a flow control weir.
  • Page 45 3.1 PC6 Particle Counter Laser Condition Percentage readout reflecting changes in laser operating current. This value is pro- vided for diagnostic information only. Laser current will change as a function of laser temperature and age. The laser percentage will increase over the lifetime of the laser and also when ambient air or water temperature increases.
  • Page 46 It is recommended to leave the flow rate at 75 ml/min unless changes to this setting have been previously discussed with Chemtrac. Units Options are “Raw”, “per ml” or “per 100 ml”. If “Raw” is selected, the particle count data will represent all particles that passed through the sensor during the sample period.
  • Page 47 Termination Enabled Use the checkbox to enable the use of a termination resistor. Byte Swap To support different microprocessors that store data in different formats, the HydroAct 4 can alter the data it sends and receives to match the format expected by the sensor. The byte swap option allows the order of bytes in the 16-bit registers to be reversed.

  • Page 49 Alarms are the means by which values obtained from sensors cause visible, audible or physical actions to occur. Alarms are not to be confused with relays. An alarm in a HydroAct 4 unit will create a visible bar across the top of the screen and sound a buzzer. One flow alarm per sensor and two data alarms per parameter are available.

    For example to a SCADA for data acquisition or to a pump for dosing control. The two types of output used by HydroAct 4 are the analog output and relay In order to utilize the full capability of the instrument it is necessary to link the signal/value and an output device, such as an alarm, threshold or control options for the relays or analog outputs.

    For example a 4-20mA output at the analyzer could end up being 3.95mA to 19.9mA at the end of the cable. The HydroAct 4 has the capability to drive more or less current to account for this resistance so that the analog output is exactly that required at the end of the cable.
