Measurement, Relay output
71 - 2 … 75 - 2 31
Module for relay output 1 … 4
The pulse-echo measuring system can be equipped
with max. two relay modules. Each module has two relay outputs.
Two-point level switch

4 0 - 58 0 - 59 = 1 0 - 60 and 0 - 61
Coordination (Module 1, relay output 1) MODE 0 - 43
For each relay output the coordination can be
programmed separately and relates to: - measurement (channel 1, 2 and difference)
- measuring unit
- level / volume percentage
vessel geometry / measuring result measuring unit coordination linearization

channel 2 m = 3
% = 4 0 - 28 = 1
difference m = 5
% = 6
volume percentage channel 1 % = 2 0 - 18 = 2
