2.3 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.
Tip
Write protecting the transmitter prevents accidental changes to configuration. It does not prevent
normal operational use. You can always disable write protection, perform any required configuration
changes, then re-enable write protection.
The SECURITY jumper enables write protection.
• If the jumper is in the ON position, write protection is enabled.
• If the jumper is in the OFF position, write protection is disabled.
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 SECURITY jumper to the ON position.
The location of the security switch depends upon whether or not the transmitter has
the (M5) optional display.
