  • Page 7: Considerations

    CONSIDERATIONS General Electrical temperature sensors such as RTDs and thermocouples produce low-level signals proportional to their sensed temperature. The Models 244EH and 244ER transmitters convert the low-level sensor signal to a standard 4–20 mA dc signal that is relatively insensitive to lead length and electrical noise.

    Multichannel Installations Several transmitters can be connected to a single master power supply as shown in Figure 2-9. In this case, the system may be grounded only at the negative power supply terminal. In multichannel installations where several transmitters depend on one power supply and the loss of all transmitters would cause operational problems, consider a back-up battery or power supply that cannot be interrupted.

    Screen Conventions The Models 244EH and 244ER Configuration Software follows the Microsoft Windows screen conventions with the following exception: Configuration parameters change color to indicate fields where information has changed. Before placing a new transmitter into service, or before returning a transmitter to service after changing configuration information, verify that the values in the fields that have been changed reflect the correct configuration parameters for your application.

NOTE Verify that the Model 244EC “Low Battery” LED is not on before initiating communication with the transmitter. If the low battery LED is on, you will not be able to configure the transmitter.

  • Page 21: Sensor Connections

    Use the following steps to wire the transmitter: 1. Connect the positive lead from the power supply to the transmitter terminal marked “+” and the negative lead to the transmitter terminal marked “–” (see Figure 2-11 and Figure 2-13). 2. Tighten the terminal compression screws to ensure adequate contact.

However, a 3-wire sensor will not fully cancel lead resistance error because it cannot compensate for imbalances in resistance between the lead wires.

You can use these RTDs in 3-wire configurations by leaving the unneeded leads disconnected and insulated with electrical tape. ** The transmitters must be configured for a 3-wire RTD in order to recognize an RTD with a compensation loop.

    To protect against high-energy transients, install Models 244E into a suitable connection head with the Rosemount Model 470 Transient Protector. The Model 470 prevents damage from transients induced by lightning, welding, heavy electrical equipment, or switching gears.

  • Page 26: Grounding

    Rosemount Models 244EH and 244ER PC-Programmable Temperature Transmitters Grounding The transmitter will operate with the current signal loop either floating or grounded. However, the extra noise in floating systems affects many types of readout devices. If the signal appears noisy or erratic, grounding the current signal loop at a single point may solve the problem.

    Configuring a Single Transmitter NOTE See “Configuration Software” on page 2-9 for instructions on how to install the configuration software. To configure a single Model 244EH or 244ER transmitter, perform the following procedure: 1. Disconnect power to the transmitter if the transmitter is installed in a measurement loop.

    Viewing the Process With version 2.0 and later of the Model 244EC Configuration Interface, users can view the measured temperature (PV) by selecting SERVICE Variable from the menu bar of the main configuration window (see Figure 3-2). In order to view a valid PV, a temperature sensor must be connected to the Model 244E transmitter, and the transmitter must be configured properly for that sensor type.

    Rosemount Models 244EH and 244ER PC-Programmable Temperature Transmitters Figure 4-1 illustrates an example of intermittent sensor detect with damping enabled. If the temperature undergoes a step change greater than the threshold value, or from 100 degrees to 110 degrees, and the damping is set to 5.0 seconds, the transmitter calculates a new reading...

  • Page 33: Implementation

    Transmitter Behavior with Intermittent Sensor Detect ON When the Intermittent Sensor Detect feature is switched ON, the transmitter can eliminate the output pulse caused by intermittent open sensor conditions. Process temperature changes (∆T) within 2% of the output range will be tracked normally by the transmitter’s output. A ∆T greater than 2% of the output range will activate the intermittent sensor algorithm.
