It is recommended to use the G60 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 G60.
• Cycle power to G60.
• Break then re-establish the communication link between the RRTD unit and the G60. This will cause the
RRTD COMM
FAIL
operand to be asserted then de-asserted.

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 G60 reads and saves all application and type settings from the RRTD. This synchronizes the RRTD and
G60. Any changes to RRTD settings (function, application, or type) from the G60 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.
