Changing Jumper Position

WARNING
Personal injury or property damage caused by fire or explosion may occur if the following procedure is attempted in an
area which contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification
and atmosphere conditions permit the safe removal of the instrument cover before proceeding.
Use the following procedure to change the position of the alarm jumper:
1. If the digital level controller is installed, set the loop to manual.
2. Remove the housing cover on the electronics side. Do not remove the cover in explosive atmospheres when the
circuit is alive.
3. Set the jumper to the desired position.
4. Replace the cover. All covers must be fully engaged to meet explosion proof requirements. For ATEX approved
units, the set screw on the transducer housing must engage one of the recesses in the cover.

Loop Test

Field Communicator Service Tools > Maintenance > Tests > Loop Test (3-4-1-2)
Loop test can be used to verify the controller output, the integrity of the loop, and the operations of any recorders or
similar devices installed in the loop. To initiate a loop test, perform the following procedure:
1. Connect a reference meter to the controller. To do so, either connect the meter to the test connections inside the
terminal box (see the Test Connections procedure) or connect the meter in the loop as shown in figure 2‐9.
2. Access Loop Test.
3. Select OK after you set the control loop to manual.
The Field Communicator displays the loop test menu.
4. Select a discreet milliamp level for the controller to output. At the "Choose analog output" prompt, select 4 mA,
20 mA, or Other to manually input a value between 4 and 20 milliamps.
5. Check the reference meter to verify that it reads the value you commanded the controller to output. If the readings
do not match, either the controller requires an output trim, or the meter is malfunctioning.
After completing the test procedure, the display returns to the loop test screen and allows you to choose another
output value or end the test.
