Use Force High With Hart; Root Menu - GE PanaFlow HT User Manual

D.1.2 Write Mode Switch (cont.)
Note:
The following sections of this Appendix provide a map to programming functions via HART communication.
To make programming changes through HART, the HART circuit must be set to "write" mode. If your HART
device cannot make program changes, inspect the switch to be sure your HART circuit is in "write" mode.
D.1.3 Use Force High with HART
The Authorized User may select Force High or Force Low for the Dangerous Detected state, the mA level that the SIL
Output will go to in case of an error detection. If the HART signal is going to be used by the system for frequent
communication, we recommend selecting Force High. The Force Low level, 3.6 mA, is marginally capable of carrying
HART signals. By selecting Force High, 21.0 mA, the Operator can be confident that in case of a fault condition HART
communication will be available to diagnose the cause of the fault
