Setup
Determination of the response height
For horizontally mounted instruments, the in-
stallation height determines the response
height.
For vertically mounted instruments, the re-
sponse height is determined by the length of
the electrode rods.
Modifying the response height by changing
the rotary switch setting (conductance) is not
recommended.
The response height can be corrected by
shortening (sawing off) the measuring rods.
Before shortening, the rods must be re-
moved from the plastic threaded mounting of
the sensor.
The numbers of the rods are visible on the
lower side of the thread.
The ground rod (no. 1) should have the same
length or should be even longer than the other
rods.
The max. rod (no. 2) defines the response
height for single point level switches or the
upper switching level with double point control.
The min. rod (no. 3) defines the lower switching
level, it is always longer than the max. rod. It is
missing on instruments for single point level
detection.
The sensor electronics recognizes if a min.
rod is screwed in and changes automatically
from single to double point control.
Level detection for max. signal
• Fill the vessel until the shortest electrode is
immersed approx. 1 cm.
• Switch on the power supply.
• Set the A/B switch to mode A.
• Set the rotary switch to position "TEST min".
• Turn the rotary switch slowly clockwise until
the red LED lights.
• The instrument is adapted to the medium,
i.e. the relay deenergises at max. level.
Level detection for max. signal
• Empty the vessel until the min. electrode is
immersed approx. 1 cm.
• Switch on the power supply.
• Set the A/B switch to mode B.
• Set the rotary switch to position "TEST
max".
• Turn the rotary switch slowly anticlockwise
until the red LED lights.
• The instrument is adapted to the medium,
i.e. the relay deenergises at min. level.
