  • Page 14: Enable Transmitter Write Protection

    Installation and commissioning Enable transmitter write protection Write-protection helps protect the transmitter against accidental changes to configuration. When the transmitter is write-protected, no changes to the transmitter configuration will be accepted. Write protecting the transmitter prevents accidental changes to configuration. It does not prevent normal operational use.

    Installation and commissioning Figure 2-3: SECURITY jumper location with M5 optional display Replace the transmitter housing cover. Power up the transmitter. 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.
