SUBMENU FACTORY OR USER
«CalSelct» allows to view either the factory settings «Factory» or the super user modified settings «User». Spare heads
will be configured per factory default values and will be different from the super user modified settings. The super user settings
overrule the factory settings, whereby the factory settings can at all times be referenced to, to allow efficient troubleshooting.
USER CALIBRATION PROCEDURE
Use this procedure
- for matching new E3 electronics with older generation EZ Modulevels
- when replacing spare parts: Electronic module, LVDT assembly, range spring, stem assembly or displacer
- for exchanging a complete electronics head on a E3 Model.
NOTE: This procedure should be performed at normal operating conditions.
Capturing the 4mA value
1. Move liquid level on displacer to desired low level point. Using keypad and LCD display, scroll down to DispFact.
2. Press to access data entry mode, then until “Yes” is displayed and again. The factory menu is now accessible.
3. Scroll down to CalSelct.
4. Press , then until “User” is displayed and again.
5. Press to UserCalMenu and press to show the menu.
6. Scroll down to SnrCalLo.
7. Press , then and simultaneously and again. The current liquid level has been captured as the low level point.
8. Scroll down to LvlCalLo. The default value is 0.00. If a different level value is desired at this point, press , use the
and keys to choose the desired value and press again.
Capturing the 20mA value
9. Move the liquid level on displacer to the desired high level point. Scroll to SnrCalHi.
10. Press , then and simultaneously and again. The current liquid level has been captured as the high level
point.
11. Scroll down to LvlCalHi. The default value is an arbitrary length. Press , use the and keys to choose the level
value and press again. The user calibration is complete.
NOTE: PACTware™ provides a user friendly way to remotely perform the identical procedure
