September 2017

4.0 Set switches and jumpers

If alarm and security adjustment option is not installed, the transmitter will
operate normally with the default alarm condition alarm "high" and the security
"off".
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 electronics compartment cover. On the PlantWeb housing the
cover is opposite the field terminals side, or on the junction box housing
remove the terminal block cover. Do not remove the housing cover in
explosive environments.
3. On the PlantWeb housing, slide the security and alarm switches into the
preferred position by using a small screwdriver (an LCD display or an
adjustment module must be in place to activate the switches). On the junction
box housing pull the pins out and rotate 90° into desired position to set the
security and alarm.
4. Reinstall the housing cover so that metal contacts metal to meet
explosion-proof requirements.
