FAULT CONTACT
The contact is always closed when measurement functions correctly.
The fault contact opens in the event of a fault in the connected sensor.
The type of fault is indicated at the display (TR: receiver fault, TT: emitter fault). If measured turbidity is significantly greater than the maximum
measuring range of the sensor, fault message TT (emitter fault) is displayed.
All contacts are always open in the event of a fault!
RESET TO DEFAULT SETTINGS
Switch power supply on!
Within 3 seconds (i.e. during the test routine), press and hold the rotary/pushbutton selector for approximately 5 seconds:
The display counts up: 1, 2, 3, 4... 99 ST (ST = default values are loaded).
All settings are returned to their default values (factory settings).
SWITCHING SUPPLY POWER ON (TEST ROUTINE)
After supply power has been switched on, the device starts a test routine during which all LEDs and the digital display are activated (LED test).
After about 5 seconds, the evaluation units software version is briefly displayed.
The display is then “limit value display”.

Measurable turbidity values depend on the process medium and the nominal diameter of the piping.
Minimum acquirable turbidity in the LOW range begins at roughly 50...100FAU.
Maximum detectable turbidity in the HIGH range: approx. 3000...10000FAU (corresponds to approx. 10...30g/l SiO₂).
Maximum detectable turbidity in the MEDIUM range: 10% of the HIGH range.
Maximum detectable turbidity in the LOW range: 1% of the HIGH range.
