Notes:
• Setting P001 resets Span (P007), unless Span has previously been set to a different
value. Span is set to Empty distance minus 110% of Blanking
(distance measurement). In this case Span is set to the same value as Empty (P006).
• Changing P001 may reset Output Function (P201).
P002 Material to be monitored
For use only by Siemens service personnel.

Changing P003 resets the following parameters: P070, P700, P701, P709, and
Note:
P711.
Use a setting just faster than the maximum filling or emptying rate (whichever is greater).
Slower settings provide higher accuracy: faster settings allow for more level fluctuation.
• Echo Verification (P711): discriminates between agitator blades in motion (spurious
noise) and the target surface (true echo).
• Failsafe timer (P070): establishes the period from the time a loss of echo (LOE) starts
until the Failsafe default (P071) is triggered. P070 takes precedence over P003.
