To set the relay coil state
Figure 4-25: Relay coil state menu
Note: You can specify the relay coil state (energized or de-energized) to meet any
particular application requirement. For example, Relay 1 coil is de-energized
during an active status when a measurement or analyzer fault is detected.
Therefore, if the power to the analyzer fails, or the relay cable is disconnected, a
fault is raised because this is electrically the same as if Relay 1 is de-energized.
This is a ‘fail
-
safe’ situation. In some applications it is preferable that the relay is
energized in an active status.
