5. Power up the transmitter.
2.4 Set failure mode
As part of normal operations, the flowmeter continuously runs a self-diagnostic routine. If
the routine detects an internal failure, the failure mode setting determines whether the
flowmeter output is driven to a low or high alarm level.
The failure mode setting is controlled by the ALARM jumper, which is set at the factory per
the CDS (Configuration Data Sheet); the default setting is HI.
If the ALARM jumper is in the HI position, the flowmeter output will be driven to a
high alarm level in the event of a failure.
If the ALARM jumper is in the LOW position, the flowmeter output will be driven to a
low alarm level in the event of a failure.
Note
For exact alarm values, see the product reference manual.
Procedure
1. If you are in a hazardous area, power down the transmitter.
2.
WARNING!
Never remove the transmitter housing cover in a hazardous area when the transmitter is
powered up. Failure to follow these instructions may result in an explosion.
Remove the transmitter housing cover (opposite of the terminal block).
3. Move the two-pin ALARM jumper to the HI or LOW position, as desired.
