The setting ranges for the switching limits (SPx, rPx, FHx, FLx, OP) depend on the
probe length (L):
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
cm inch
min max min max
[OP] 7�0 L - 3 2�8 L - 1�2
Hysteresis (fixed) 1�0 1�0 0�4 0�4
Step increment 0�5 0�2
Moreover, the following applies:
• 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�
14 Maintenance
Always observe the admissible application area to avoid damage and to
reduce maintenance (→ 4.2) !
► Keep the ventilation hole and the interior of the coaxial pipe free from deposits
and foreign bodies� Observe application area (→ 4.2) !
► In case of soiling: Clean probe at regular intervals�If soiling occurs: It is
absolutely necessary to take measures to prevent soiling� Observe application
area (→ 4.2) !
In case of longer operation separation layers can form in the medium
(e�g� oil on water)� It is possible that a separation layer may form inside the
coaxial tube!
► Remove separation layers at regular intervals (e�g� remove oil by suction)�
