5.9 TRANSDUCER INPUTS AND OUTPUTS
RTD INPUT H1 TYPE: This setting specifies the RTD type. Four different RTD types are available: 100 Ω Nickel, 10 Ω
•
Copper, 100 Ω Platinum, and 120 Ω Nickel. Refer the table below for reference temperature values for each type.

• RTD INPUT H1 APPLICATION: This setting allows each individual RTD to be assigned to a group application. This is
useful for applications that require group measurement for voting. A value of "None" specifies that the RTD will operate
individually and not part of any RTD group. All RTDs programmed to "Stator" are used for RTD biasing of the G60 ther-
mal model. Common groups are provided for rotating machines applications such as ambient, bearing, group 1, or
group 2. If the

same group also pick up, where N is the number of enabled RTDs from the group.
• RTD INPUT H1 ALARM TEMPERATURE: This setting specifies the temperature pickup level for the alarm stage.
• RTD INPUT H1 ALARM PKP DELAY: This setting specifies time delay for the alarm stage until the output can be
asserted.
• RTD INPUT H1 TRIP TEMPERATURE: This setting specifies the temperature pickup level for the trip stage.
• RTD INPUT H1 TRIP PKP DELAY: This setting specifies time delay for the trip stage until the output can be asserted.
