Ground fault detection
The Rosemount 2240S has a built-in function for ground fault detection. When the ground fault detector
is enabled, a faulty temperature sensor is indicated in a status register (see
). A single fault will affect the measurement on all channels.
If one of the temperature elements fails, for example caused by a short circuit to ground, you can change
the jumper setting to temporarily disable ground fault detection, see
Figure 6-1. Jumper for Ground Leakage Detection
Note
Ground fault detection should only be used as a temporary solution in case of a malfunctioning
temperature element. The faulty temperature element must be replaced for accurate measurement. See
“Test and simulation” on page 115
