The user can select the "Mode Block" parameter at the LCD. In this case is necessary to select the
index equal to "Mode Block":
Figure 3.20 - Parameters for Local Adjustment Configuration
Calibrating using Local Adjustment
The positioner has two holes for magnetic switches, located under the identification plate (See the
section "Programming Using Local Adjustment"). These magnetic switches are activated by one
magnetic tool.
This magnetic tool enables adjustment of the most important parameters of the blocks. It also
enables pre-configuration of the communication.
The jumper J1 on top of the main circuit board must be in place and the positioner must be fitted
with the digital display for access to the local adjustment. Without the display the local adjustment is
not possible.
In order to enter the local adjustment mode, place the magnetic tool in orifice “Z” until flag “MD”
lights up in the display. Removes magnetic tool from “Z” and place it in orifice “S”. Remove and
reinsert the magnetic tool in “S” until the message “LOC ADJ” is displayed.
The message will be displayed during approximately 5 seconds after the user removes the magnetic
tool from “S”. By placing the magnetic tool in “Z” the user will be able to access the local
adjustment/monitoring tree.
Browse to parameter “LOPOS”. After that in order to start the calibration, the user shall activate
parameter “LOPOS” with the help of the magnetic tool placed in “S”. For example, it is possible to
enter 0%. When the magnetic tool is removed from “S”, the output will be set to a value close to the
desired value. The user shall then browse the tree up to parameter FEED (FEEDBACK_CAL), and
actuate this parameter by placing the magnetic tool in “S” until reaching the value obtained from the
position reference.
The user shall continue to write in this parameter until it reads 0% or the desired lower position
value. Browse to parameter “UPPOS”. After that, in order to start the calibration, the user shall
actuate parameter “UPPOS” by placing the magnetic tool in “S”. For example, it is possible to enter
100%. When the magnetic tool is removed from “S”, the output will be set to a value close to the
desired value. The user shall them browse the tree up to parameter FEED (FEEDBACK_CAL), and
actuate this parameter by placing the magnetic tool in “S” until reaching the desired value.
With this option,
the Mode Block
parameter is
shown at the
LCD.
