VEGA VEGASON 71 - 2 … 75 - 2 - Manual (Page 21)

Adjustment at level measurement
71 - 2 … 75 - 2 21
Empty / full adjustment in m without product level change
Programming pre-requirement
Mode 10 = 1
Mode 40 = 11 With this adjustment procedure two distances
(sensor … product surface) are defined in m
relating to the levels of 0 % and 100 %.
MODE 0 - 11 and 0 - 12
Programming example with VEGASON 73 - 2 (individual programming sequence of the empty /
full adjustment)
• select mode 0 - 12 in MODEFIELD
• program 01.00 m in PARAMETER FIELD
• then store with STO-button
• select mode 0 - 11 in MODEFIELD
• program 09.00 m in PARAMETER FIELD
• then store with STO-button
Empty / full adjustment in % with product level change
Programming pre-requirement
Mode 10 = 3
Mode 40 = 11
MODE 0 - 11 and 0 - 12
Programming example with VEGASON 73 - 2 (individual programming sequence of the empty /
full adjustment)
• select mode 0 - 12 in MODEFIELD
• program 075.0 % in PARAMETER FIELD
• then store with STO-button
• select mode 0 - 11 in MODEFIELD
• program 025.0 % in PARAMETER FIELD
• then store with STO-button
With this adjustment procedure two levels are
defined in % relating to two different, actually
measured distances (sensor … product surface). The difference should be as large as possible. The
central electronics determines the adjusted range
(e.g. 25 … 75 %) from the total range (0 … 100 %).
Same procedure for channel 2, however
mode 0 - 21 and 0 - 22.
