Transmitter Security

The failure mode alarm jumper is located on the LCD faceplate in the electronics module side of the transmitter housing and is labeled ALARM (See Figure 3-11). Do not remove the transmitter cover in explosive atmospheres when the circuit is alive. Both covers must be fully engaged to meet explosion proof requirements.

After commissioning the transmitter, you may wish to protect the configuration data from unwarranted changes. The transmitter is equipped with a security jumper that can be positioned to prevent changes to the configuration data (see Figure 3-11). The circuit board is electrostatically sensitive. Observe handling precautions for static-sensitive components to avoid circuit board damage.

When the transmitter security jumper is in the “ON” position, the transmitter will not accept any “writes” to its memory. This means that configuration changes (such as digital trim and reranging) cannot take place when the transmitter security is on. To reposition the jumper, use the following procedure.

1.If the transmitter is installed, secure the loop, and remove power.

2. Remove the housing cover opposite the field terminal side. Do not remove the instrument cover in explosive atmospheres when the circuit is alive.

3.Reposition the jumper. Avoid contact with the leads and the terminals. Refer to Figure 3-11 for the location of the jumper and the ON and OFF positions.

4. Reattach the transmitter cover. The cover must be fully engaged to comply with explosion-proof requirements.
