Use the following procedure to install the
correct values:
FF
1. Write parameter Actuator S/N. Make certain
the parameter is written into the DCM-3.
2. Execute Reset Settings with the option Use
Model Defaults.
HART
1. Write parameter Actuator S/N. Make certain
the parameter is written into the DCM-3. If the
HART master asks to use the default settings,
agree.
2. If the master did not automatically use default
settings, execute Use Default Setup.
BCP
1. Write the serial number with command:
sernum
2. Execute command configformodel.
After choosing the appropriate maximum
voltage range, the 0% point can be set through
parameter CPS Zero%. See OUTPUT SHAFT 0%
POSITION (page 30).
LOCAL
If a computer interface is not available, the
position sensing voltage ranges can be set using
the local configuration interface. Using the local
interface performs two functions simultaneously.
First, the voltage range end point is defined.
Second, the voltage end point is automatically
defined as 0% or 100%. The parameter Snsr Dir
(page 28) cannot be modified without a computer,
but should already be set correctly to Retract for
an increasing signal. To use the local interface,
use the procedure described under TRAVEL.
TRAVEL
The Travel parameter should not be changed
from the factory default value for Model 14
actuators. The MaxTravel parameter and Travel
parameter are factory set and should match.
If the 100% stroke travel needs to be modified
for any reason (which would be unlikely since the
Model 14 is usually factory set for a particular
valve), the stroke adjustment should be made
mechanically by adjusting the Calibar located
under the main cover (see STROKE CHANGE—
CALIBAR, page 37).
To match the desired travel distance:
FF
Modify parameter Travel.
HART
Modify parameter Travel.
BCP
travel
LOCAL
1. Move the output shaft to the desired 0%
position.
2. Press and hold “CALIBRATE” and POS 0%
until the “ACKNOWLEDGE” LED lights.
3. Move the output shaft to the desired 100%
position.
4. Press and hold “CALIBRATE” and POS 100%
until the “ACKNOWLEDGE” LED lights.
If the “POSITION” LED lights, the signal is not
within the acceptable range.
