The setting ranges for the switching limits (SPx, rPx, FHx, FLx) depend on the
probe length (L)� In general the following applies:

The values apply if [OFS] = 0� The values in brackets apply to the setting [MEdI] = [LOW]
(setting for the detection of oils and oil-based media)�
•
rPx (FLx) is always lower than SPx (FHx)� If the value for SPx (FHx) is reduced to a value
rPx (FLx), the position of rPx (FLx) also shifts�
•
If rPx (FLx) and SPx (FHx) are close together (approx� 3 x step increment), rPX (FLx) is
changed automatically when SPx (FHx) is increased�
•
If there is a greater distance between rPx (FLx) and SPx (FHx), rPx (FLx) maintains the set
value even if SPx (FHx) is increased�
14 Maintenance
►
Keep the process connection free of deposits and foreign bodies�
►
In case of heavy soiling: clean the process connection and the probe at regular
intervals�
In case of long operation separation layers can form in the medium (e�g� oil on
water)� This applies especially to still pipes or bypasses:
►
Remove separation layers at regular intervals�
►
Ensure that the vent hole (at the upper end of the coaxial pipe) remains free�
►
Keep the interior of the coaxial pipe free from foreign bodies and soiling�
