The unit signals via four switching outputs that set limits have been exceeded or
that the level is below the limit.
• Outputs OUT1 / OUT2 are assigned to the process value
level
.
• Outputs OUT3 / OUT4 are freely programmable:
Parameter [SEL3] / [SEL4] assigns the process value, level / temperature, to
the outputs OUT3 / OUT4
.
Selectable switching functions:
• Hysteresis function / normally open (Fig. 5-2):
[oux] = [Hno].
• Hysteresis function / normally closed (Fig. 5-2): [oux] = [Hnc].
First the set point [SPx] is set, then the reset point [rPx] with the requested
difference.
The hysteresis for the overflow prevention OP is fixed.
• Window function / normally open (Fig. 5-3):
[oux] = [Fno].
• Window function / normally closed (Fig. 5-3):
[oux] = [Fnc].
The width of the window can be set by means of the difference between
[FHx] and [FLx]. [FHx] = upper value, [FLx] = lower value.
