4.2 Switching function
OUT1 changes its switching state if it is above or below the set switching limits
(SP1, rP1) The following switching functions can be selected:
Hysteresis function / normally open: [OU1] = [Hno] (→ fig. 1).
•
Hysteresis function / normally closed: [OU1] = [Hnc] (→ fig. 1).
•
First the set point (SP1) is set, then the reset point (rP1) with the requested differ-
ence
Window function / normally open: [OU1] = [Fno] (→ fig. 2).
•
Window function / normally closed: [OU1] = [Fnc] (→ fig. 2).
•
The width of the window can be set by means of the difference between SP1 and
rP1 SP1 = upper value, rP1 = lower value

T = system temperature; HY = hysteresis; FE = window
4.3 Analogue function
[OU2] defines if the set measuring range is provided as a 420 mA signal
•
([OU2] = [ I]) or a 010 V signal ([OU2] = [U])
Analogue start point [ASP] defines at which measured value the output signal
•
is 4 mA / 0 V
Analogue end point [ AEP] defines at which measured value the output signal
•
is 20 mA / 10 V
Minimum distance between [ASP] and [AEP] = 5 K
