Transmitter M400 1 9 Introduction Statement of Intended Use – The M400 multiparameter transmitter is a single- channel online process instrument for measuring various properties of fluids and gases. These include Conductivity, Dissolved Oxygen, Dissolved Carbon Dioxide (CO2) and pH / ORP. The transmitter handles also ISFET sensors used for pH measurement. The M400 is available in three different levels. The level indicates the amount of measurement parameters which can be covered.

Transmitter M400 72 If an ISM sensor has been connected resp. configured there is furthermore the option to adjust the polarization voltage for the sensor. Different value can be entered for the measuring mode (Umeaspol) and for the calibration mode (Ucalpol). For entered values 0 mV to –550 mV the connected sensor will be set to a polarization voltage of –500mV. If the entered value is less then –550mV, the connected sensor will set to a polarization voltage of –674mV.
Transmitter M400 73 In the next step the salinity of the measured solution can be modified. In addition the relative humidity of the calibration gas can also be entered. The allowed values for relative humidity are in the range 0% to 100%. When no humidity measurement is available, use 50% (default value). Pressing the [ENTER] key again will bring up the Save Changes dialog. Selecting No will discard the entered values and return to the measurement display screen, selecting Yes will save changes made.
Transmitter M400 74 Depending on the measured media temperature the LED of the sensor can be automatically switched off. If the media temperature is higher then Toff, the LED will switched off. The LED will be switched on as soon as the media temperature falls below Toff - 3K. This function give the option to increase the lifetime of the OptoCap by switching off the LED thru SIP or CIP cycles. h NOTE: This function is only active if the operation mode of the LED is set to “Auto”.
Transmitter M400 75 The Salinity describes the total amount of solved salts in the CO2 electrolyte of the sensor connected to the transmitter. It is a sensor specific parameter.

Transmitter M400 77 Pressing the [ENTER] key again will bring up the Save Changes dialog. Selecting No will discard the entered values and return to the measurement display screen, selecting Yes will save changes made. 8.4 Set points (PATH: Menu / Configure / Set Points) Enter Configuration mode as described in Section 8.1. “Enter Configuration Mode” and navigate to the menu “Set Points” by using the or . key. Press the [ENTER] key to select this menu.
Transmitter M400 78 Hold Enter the Relay Hold Status of ”Last”, ”On” or ”Off”. This is the state the relay will go to during a hold status. State Relay contacts are in normal state until the associated setpoint is exceeded, then the relay is activated and the contact states change. Select ”Inverted” to reverse the normal operating state of the relay (i.e. normally open contacts are in a closed state, and normally closed contacts are in an open state, until the setpoint is exceeded).
Transmitter M400 79 If any of these criteria are set to Yes and the conditions for an alarm are given, the flashing symbol a will be shown in the display, an alarm message will be recorded (see also chapter Messages; PATH: Info/Messages) and the selected relay will be activated. Furthermore an alarm can be indicated by the current output if this has been parameterized (see chapter 8.3 “Analog outputs”; PATH: Menu/Configure/Analog Outputs) The conditions for alarms are: 1.
Transmitter M400 8.5.2 80 Clean Configure the relay to be used for the cleaning cycle. The default value is relay 1. The cleaning interval can be set from 0.000 to 999.9 hours. Setting it to 0 turns the clean cycle off. The cleaning time can be 0 to 9999 seconds and must be smaller than the cleaning interval. Select the desired Relay state: Normal or Inverted. Pressing the [ENTER] key again will bring up the Save Changes dialog.
Transmitter M400 81 The sensor keeps the information stored in the built in electronics and can be retrieved via a transmitter or the iSense asset management suite.
