Siemens Sitrans, LC 500 Transmitter Variable Values menu level, Upper Range Value

Upper Range Value

Upper Range Value (URV) is the setting for 100% of the operating range, in most cases a full vessel/tank. The transmitter variable on which this menu selection operates is chosen in Menu 01. For TV0, the URV is in most cases Factory Set to the probe capacitance in water.

The increment/decrement step size is subject to the setting from Menu 09.

1.Set the rotary switch to F.

2.Press and hold both buttons simultaneously to take the current PV reading as the new setting.

or: Press the RED (+) or BLUE(–) button to step this value up or down.

or: Press and hold a button for a prolonged time to start a repeat function.

When the new setting exceeds that of the Limit Settings (Menu 0C and 0B), the new value is rejected, and the previous value remains unchanged.

Transmitter Variable Values: menu level 0

Dynamic Value, Primary Variable (PV): menu 00 and menu 10

Note: Menus 00 and 10 are the only locations where you can change from level 1 to level 0, or vice versa.

The value for the Primary Variable is displayed as either units or percent of range, selected in menu 01. When 2-state mode is selected in menu 07 the LCD display indicates the probe status:

•blinking for an uncovered probe

•steady for a covered probe

If the internal diagnostics detect a fault or failure, the display alternates between the PV value and the fault/failure message ‘Flt’. If the product level goes outside the limit settings, then the display alternates between the PV value and ‘ooL’. Alternatively, if the simulation
