Resticted Menu Routines
Section 3: Restricted Menu Routines
3.16.6 4 - 20 mA Config
This routine is used to calibrate the 4 - 20 mA input and outputs. This is normally done in-house.
Should it be necessary to recalibrate the 4 - 20 mA input and output, this needs to be conducted in
two steps.
Reconfigure the limits of the A/D and D/A converters of the base card as follows:
• Enter VIEW and SETUP menu as described in the XTE3000 IOM.
• Select the language.
• Select SETUP mode.
• Enter the Level 2 password.
• Select ACTUATOR SETUP.
• Scroll the list of routines and press YES when the message displayed is "RESTRICTED."
• Press YES to scroll the list of "RESTRICTED" routines and press NO when the message
displayed is "EXIT OK?"
• Press YES until the message displayed is "4 - 20 mA CONFIG. CHANGE?"
• Press YES to enter the "4 - 20 mA CONFIG." routine. The message displayed will be
"READ OK?"
• Press YES to view or change the configured values corresponding to I = 4 mA (from 0 to
2000), I = 20 mA (from 2000 to 4095), O = 4 mA (from 0 to 2000), O = 20 mA (from 2000 to
4095). Press YES to confirm and skip to next step or press NO to change. Values out of range
cause a CONFIGURATION alarm.
• Or press NO to skip to "SETUP OK?"
• When the message displayed is "SETUP OK?" press NO to exit or press YES to recalibrate:
— Connect a 4 - 20 mA current generator to terminals B8/B9 and a multimeter in mA
to terminals C10/B7 in accordance with the electrical diagrams.
— The message displayed is "I = 4 mA=xxxx."
— Set the current generator to 4 mA. The displayed value should be from 0 to 2000.
Press YES.
— Set the current generator to 20 mA. The displayed value should be from 2000 to
4095. Press YES.
— Press NO until the multimeter indicates 4 mA. The displayed value should be from
0 to 2000. Press YES.
— Press NO until the multimeter indicates 20 mA. The displayed value should be
from 0 to 2000. Press YES.
— Exit from the configuration menu.
3.16.7 Current Sensor
This routine includes the calibration values of the current sensor. Calibration of the current sensor
is done in-house. Enter the routine only if a new setting is required. There are two options available:
READ and SETUP. In READ mode the operator can view and change the values corresponding to
currents 2 A, 3.5 A, 7 A, 15 A, and 30 A via the local operator interface. Do not enter SETUP mode.
When the message displayed is "CURRENT SENSOR CHANGE?" press NO to skip to next routine or
press YES to enter. The display will show the message "READ OK?" Press YES to view or change the
values. If the NO push button is pressed the message displayed will be "SETUP OK?" Press NO to exit.
