RIO4000 Module Instructions


For RTD (Resistance Temperature Detector) Measurement and Simulation when used with the MFT 4000
Series Multifunction Calibrator / HART Communicator.


Safety Notice:
RIO4000 modules require Intrinsically Safe MFT base unit in order to be Intrinsically Safe themselves.
The RIO module must only be installed or removed in a safe area. Similarly, RTDs and User Cables must only be
connected to or removed from the RIO4000 module in a safe area. For more information on Intrinsically Safe
operation, see the MFT instruction manual section on this topic.

RTD Types Supported for Measure and Simulate

The RIO4000 Module will measure and simulate temperature for twenty-two (22) RTD types and will accommodate 2-,
3-, and 4-wire configurations for measure and 2-wire configurations for simulate. To enter any of the modes of
operation for the RIO module, select the

More soft key, then select the Sensr soft key and the following screen will

appear.














Information for the module in the 1

st

bay location will appear as in this example where the RIO module is installed in

Bay 1. Otherwise select

Next soft key to select the correct bay location.


From this window, select the

Setup soft key to start the user interface for:

- simulation

mode

- measure

mode

- Rcal

Mode


1.0 Simulation Mode

1.1 Connectors and Wiring Configurations

A Simulation Cable (by manufacturer) must be used for simulation applications. When the simulation
cable is plugged into the RIO module, it will automatically be detected and will not allow any measure
mode operations. The RIO module can simulate to conventional and smart transmitters.

Special Note:

In order to maintain the RIO module’s accuracy statement, some Pulsed transmitters

(Rosemount 3144, 644) must be placed in “Active Calibration” mode or a similar continuous mode prior to
simulating RTD Type resistance to the transmitter sensor input circuitry.


1.2 Simulation Mode User Interface

Plug the Simulate Cable into a RIO module that has already been inserted into an MFT Bay.
To setup a simulation from the RIO Setup Menu, select

Simulate Mode from the RIO Setup.



NOTICE: The calibrator firmware must be Version 3.42 or later in order for proper
RIO4000 module operation.
