System Integration and Operation
Initial Setup
After mounting the ICoT and installing it in the desired control valve system, following the instructions of
Section 3(Mechanical and Pneumatic Installation (Valve Setup)), and after following the field wiring
instructions described in Chapter 4(Power / Network and Field wiring – Direct Mount), the ICoT is ready
to be calibrated and configured.
The different ways to calibrate and configure the ICoT is described in Sections 8.9, 8.10 and 8.12.
It is mandatory to perform at least one successful calibration before properly operating
the ICoT positioner
.
Section 8.13 (FF System Configuration Examples) describes some configuration examples using two
different control systems.
Factory Default Initialization
The ICoT positioner is a microprocessor controlled digital device. Its operation relies on data that is
stored in the positioner’s non-volatile memory. Calibration and configuration data that has been
established during the positioner’s setup and calibration is stored in this memory. Under certain
abnormal conditions this stored information can become corrupted. If this occurs it is necessary to reset
the memory and re-calibrate the positioner by initializing the ICoT in factory default mode.
Using the Keypad:
1.
Power down the device.
2.
Press and hold the “CAL” button, and power up the device.
3.
Release the “CAL” button when the message “Factory Default initialization” is shown on the
display.
4.
Pressing the “Down” button, select one of the options:
a.
“NO” to cancel the “Factory Default Initialization” procedure.
b.
“YES” to reset all non-volatile data to default with exception of the position calibration
data.
c.
“ALL”: It is reserved for future usage. It does the same function as selecting the option
“YES”, i.e., reset all non-volatile data to default with exception of the position calibration
data.
5.
Press the “CAL” button to execute the selected option.
6.
Other options are described in Section 9.2.2.4 (How do I perform a factory default initialization?)
This procedure will have the same behavior of doing the factory default initialization
procedure using the DIP switch or using the Resource Block (See Section 9.2.2.4).
