    7200 Monitor Instruction Manual 1 Health & Safety Information The following information is a guide and does not in anyway replace legal requirements for the handling of the equipment and chemicals or any safe working practise defined outside of this manual.

  • Page 7: Introduction

    The measurement title, units and display range can all be user set to suit the sensor being used and the parameter being monitored. Key Pad A six key tactile membrane keypad is used for all configuration and operation of the 7200 Monitor, each key has a very positive operation enabling use even whilst wearing gloves. Alarms Two user configurable alarms are provided within the 7200, which can be used to signal high, low or fault alarm conditions.

  • Page 8: Manual Conventions

    The manual has been written on the basis that the user has a basic knowledge of instrumentation and an understanding of the type of measurement being made. Training in the use of the 7200 Monitor can be provided by Partech, please contact sales for further information.

  • Page 9: Mcerts Product Certification

    The scheme provides a framework within which instruments and measurements can be made in accordance with the Agency's quality requirements. Partech Instrument's Certified Turbidity System consists of the 7200 Monitor and Turbi-Tech 2000LS Sensor. The system underwent laboratory testing in accordance with the MCERTS performance standard and can only be described as an MCERTS certified system when installed and operated as a system in accordance with recommended procedures.

  • Page 10: Installation

    5.1 Location The field mounting version of the 7200 Monitor is housed in an IP65 enclosure and therefore is suitable for mounting outdoors, preferably located close to the sensor. It is advisable to mount the monitor in a location where it has some protection from the elements, this could be inside a GRP or metal cabinet, in a control room, or with a protective shield.

  • Page 11: Electrical Connections

    If the cable being used is too large for the PG11 glands, the cable must be terminated externally to the unit and a suitable cable used for connection to the 7200. If any fitted cable glands are not used, these must be sealed to prevent the ingress of moisture into the unit.
  • Page 12 Note 1: The normal condition for the alarm outputs is when the instrument is powered and the alarm is off. Note 2: The RS232 connections can be used to collect data from the 7200 and using a suitable serial cable for connection to a PC.

  • Page 13: Basic Operational

    Measure Mode The normal operating mode for the 7200 Monitor is its measure mode and this is active when the measured value is displayed in large numbers. Whilst in measure mode the display value is continually updated based upon the current sensor input signal.
