3.4 Installation procedures
3.4.1 Configure security (write protect)
About this task
Changes to the transmitter configuration data can be prevented with the security (write
protect) switch located on the feature board. See Figure 3-1 for the location of the switch.
Position the switch in the ON position to prevent accidental or deliberate change of
configuration data.
If the transmitter write protection switch is in the ON position, the transmitter will not
accept any “writes” to its memory. Configuration changes, such as digital trim and
reranging, cannot take place when the transmitter security is on.
To reposition the switches, follow the procedure described below:
Procedure
1. Do not remove the transmitter covers in explosive atmospheres when the circuit is
live. If the transmitter is live, set the loop to manual and remove power.
2. Remove the housing cover opposite the field terminal side of the housing.
3. To reposition the switches as desired, slide the security and alarm switches into the
preferred position using a small screwdriver. See Figure 3-1.
