Connect a current meter in series with the transmitter output terminals (+31 & -32) and a voltage source (such as the
DCS analog input channel). From the home screen, press the DOWN (B) arrow key six times and then press the RIGHT
(") arrow key.
1. Use the UP (Y) and DOWN (B) arrow keys to manipulate the output current read by the current meter. When 4 mA
is read by the meter, press the RIGHT (") arrow key.
2. Again, use the UP (Y) and DOWN (B) arrow keys to manipulate the output current read by the current meter.
When 20 mA is read by the meter, press the RIGHT (") arrow key.
If you want to keep this calibration, select SAVE AND EXIT. If you exit without saving, the last saved configuration data
will be restored.
Local Control
This procedure allows the user to manually control the position of the valve (see figure 23). To enter this procedure
from the home screen, press the DOWN (B) arrow key seven times and then press the RIGHT (") arrow key.
If you select ANALOG, you will return to the home screen and the digital valve controller will respond to the loop
current. If you select MANUAL, you will move to the screen that shows the travel setpoint and the actual valve travel.
