The setting ranges for the switching limits (SPx, rPx, FHx, FLx) depend on the
probe length (L)� In general the following applies:
cm inch
min max min max
SPx / FHx 1�5 (3�5) L - 3 0�6 (1�4) L - 1�2
rPx / FLx 1�0 (3�0) L - 3�5 0�4 (1�2) L - 1�4
Step increment 0�5 0�2
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 smaller 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�
13 Servicing
► 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 longer 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�
