Dcma Outputs - GE F60 Instruction Manual

CHAPTER 5: SETTINGS
Actions based on RTD overtemperature, such as trips or alarms, are done in conjunction with the FlexElements feature. In
FlexElements, the operate level is scaled to a base of 100°C. For example, a trip level of 150°C is achieved by setting the
operate level at 1.5 pu. FlexElement operands are available to FlexLogic for further interlocking or to operate an output
contact directly.
See the following table for reference temperature values for each RTD type.
