2.3.1Security

The security jumper enables the user to write-protect the flowmeter configuration, so it cannot be changed using a HART communication device:

With the security jumper OFF, the flowmeter configuration can be changed.

With the security jumper ON, the flowmeter configuration cannot be changed. The default setting is OFF. To set the security jumper, see Figure 2-3.

2.3.2Fault output levels

The transmitter can be configured to produce downscale or upscale fault outputs. In a fault condition:

Downscale: The milliamp output goes to 2 mA; the pulse output goes to 0 Hz.

Upscale: The milliamp output goes to 22 mA; the pulse output goes to 7200 Hz.

The diagnostic LED blinks ON four times per second, whether the setting is upscale or downscale.

The default setting is downscale. To set the fault output jumper, see Figure 2-3.
