Detailed Setup and Options
Section 5: Detailed Setup and Options
The actuator must be set up as defined in Section 4.4, prior to performing the following
detailed setup.
5.1
Restarting the Actuator
You can restart the Actuator by turning off and on the main power source. The process of
restarting the actuator should be done cautiously because the CAM card is directly powered
from the device and is not able to communicate when the actuator does not have power.
WARNING: DO NOT RESTART AN ACTIVE ACTUATOR
Restarting the actuator may cause loss of control of the process.
5.1.1
Restarting HART Interface
5.1.2
When the HART Interface is restarted using Device Reset Option (Service Tool ->
Maintenance -> Reset)
5.2
Write Lock
If the actuator is write protected, that means it will prevent any external change to the static
or non-volatile data. It shall not be possible to remove write protect from Network (via DD or
Application software). This is due to the security restrictions. To disable write protect, user
must use the Actuator knobs / DIP switches. Please refer to Device Instruction Operation
Manual to know about disabling the write protect.
5.3
Simulate
CAM16/216 does not support simulation.
5.4
Calibrating Travel
You must calibrate the actuator manually after the mechanical valve travel limits are set
or changed. Calibration is required only one time after the travel limits are set or changed.
Calibration parameters are stored in a non-volatile memory, which holds the variables when
power is removed from the actuator.
5.4.1
Calibration Procedure
1.
Place the LOR selector switch to the “LOCAL/MANUAL” mode.
2.
Set travel limit switches as per the valve travel on which the actuator is attached. Refer
to VALVE AUTOMATION Manual E796 for “Limit Switch Setting Instructions”.
3.
Stroke the valve fully CLOSED, OPEN, and CLOSED using the local push buttons.
4.
The actuator automatically calibrates the “Position Feedback” from 0 to 100% scale
and makes this data available to the HART Interface.
5.
Place the LOR selector switch in the “Remote/Auto” mode to return control to the
HART Interface.
