The set unit of measurement and the switching status of the outputs are indi-

cated by LEDs�
Analogue function
The unit provides an analogue signal proportional to level� The analogue output
(OUT2) can be set as current or voltage output:
Current output analogue 4���20 mA ([OU2] = [I]); voltage output analogue
•
0���10 V ([OU2] = [U])�
The analogue start point [ASP] determines at which measured value the output
•
signal is 4 mA or 0 V�
The analogue end point [AEP] determines at which measured value the output
•
signal is 20 mA or 10 V�
Minimum distance between [ASP] and [AEP] = 25 % of the active zone�
Curve of the analogue signal:s (Factory setting):
I [mA]
U [V]

I2
L = level
A = active zone; I1 = inactive zone 1; I2 = inactive zone 2 ( → 12 Scale drawing)
S1 = zero signal (4 mA / 0 V); S2 = full signal (20 mA / 10 V)
Note the tolerances and accuracy limits during the evaluation of the analogue
signal (→ 13 Technical data).
