4.2 Switching function
OUTx changes its switching state if it is above or below the set switching limits
(SPx, rPx)� The following switching functions can be selected:
• Hysteresis function / normally open: [OUx] = [Hno] (→ fig. 1).
• Hysteresis function / normally closed: [OUx] = [Hnc] (→ fig. 1).
First the set point (SPx) is set, then the reset point (rPx) at the requested distance�
• Window function / normally open: [OUx] = [Fno] (→ fig. 2).
• Window function / normally closed: [OUx] = [Fnc] (→ fig. 2).
The width of the window can be set by means of the distance between SPx and
rPx� SPx = maximum value, rPx = minimum value�

P = system pressure; HY = hysteresis; FE = window
4.3 Analogue function
• [OU2] defines whether the set measuring range is provided as a 4���20 mA
signal ([OU2] = [I]) or a 0���10 V signal ([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 span�
