Display and operating elements

Green LED ( indicates operation):
• Flashes every 5 s:
– Indicates whether the device is operational.
Red LED ( indicates a fault or malfunction):
• Flashes five times a second (alarm signal):
– The PFM output outputs an error current that sets the output of the connected switching unit
to 3.6 mA or 22 mA. As a result, this also issues an alarm.
• Flashes once a second (warning signal):
– The temperature in the electronic insert is outside the permitted temperature range.
DIP switch (build-up YES/NO)
• Build-up YES:
– This setting is recommended for very adhesive or sticky media, e.g. honey.
• Build-up NO:
– This setting is recommended for non-adhesive or non-sticky media, e.g. water.
DIP switch(probe length > 6 m, < 6 m):
• Rope probe length > 6 m:
– Measuring range 0...4000 pF
• Rope probe length < 6 m:
– Measuring range 0...2000 pF
• Rod probe 0...2000 pF at ≤ 4000 mm
