GE Multilin T60 Transformer Protection System 5-331
5 SETTINGS 5.9 TRANSDUCER INPUTS AND OUTPUTS

It is recommended to use the T60 to configure the RRTD parameters. If the RRTDPC software is used to change the RRTD
settings directly (the application and type settings), then one of the following two operations is required for changes to be
reflected in the T60.
• Cycle power to T60.
• Break then re-establish the communication link between the RRTD unit and the T60. This will cause the RRTD COMM
FAIL
operand to be asserted then de-asserted.
b) REMOTE RTDS 1 THROUGH 12
PATH: SETTINGS TRANSDUCER I/O RRTD INPUTS RRTD RTD 1(12)
The remote RTD inputs convert values of input resistance into temperature for further operations. These inputs are
intended to be connected to any of the RTD types in common use. Specific hardware details are contained in chapter 3.
On power up, the T60 reads and saves all application and type settings from the RRTD. This synchronizes the RRTD and
T60. Any changes to RRTD settings (function, application, or type) from the T60 interface are immediately reflected in the
RRTD. The following rules are followed.
•If the RRTD 1 FUNCTION setting is “Enabled”, then the RRTD 1 APPLICATION setting value will be written to RRTD device.
•If the RRTD 1 FUNCTION setting is “Disabled”, then RRTD1 APPLICATION setting value is set as “None”.
•If the
RRTD 1 APPLICATION or RRTD 1 TYPE settings are changes, then these settings are immediately written to the
RRTD device.
