7.4.1 Resetting the FB107

Issued Feb-07
Attempt to reset the MVS back to factory default settings. Refer to
Resetting the MVS to Factory Defaults in Section 7.4.10,
Troubleshooting MVS.
If you are experiencing troubles with the RTD:
Use ROCLINK 800 to verify that the on-board RTD point is
configured as point number AI3 (RTD=AI3).
If the configuration looks correct, then use ROCLINK 800 to
produce a simulated input (within the range of the input) according
to the following values:
84Ω –40°C
100Ω
250Ω 408°C
200Ω 267°C
150Ω 130°C
: These values are approximations only. Do not use these values to
Note
calibrate the device.
Verify that the wiring to the RTD terminations is correct. Refer to
Chapter 4, Inputs/Outputs and RTD Inputs.
Verify that the user-supplied RTD probe is not faulty. Refer to the
instructions that accompanied the RTD probe.
This section presents step-by-step produces to help you troubleshoot.
You reset the FB107 to perform a type of cold start that re-establishes a
known operating point and loads the factory defaults into the
communication ports. The reset (RST) switch is located on the CPU
module, just above the RTD terminal block.
This cold start does not include any of the clearing options available in a
cold start performed using ROCLINK 800 software.
This type of reset restores the communications ports to the factory
Note:
configuration defaults. Some user-entered configuration
parameters may be lost. Therefore, back up any required data
before performing this reset.
