The sensor set consists of a receiver module with microprocessor-controlled analysis electronics and two
transmitter modules.
The sensor set generates a 4 to 20 mA output signal in accordance with the following diagram.
Measuring ranges are selected with the help of the DIP switches on the receiver module.
Settings:
TURBICUBE 20
TURBICUBE 1000

Troubleshooting:
Measuring current 22 mA = overflow
Measuring current 0 mA = wrong DIP-switch setting (no valid measuring range selected)
Indication
green LED = 1 Hz blinking
ready, measuring in operation
green LED = permanent ON
ready, measuring not in operation
green LED = OFF
no power supply or defective
Fault indication
red LED = ON
= measuring circuit faulty, (short circuit or broken)
red LED = 1 Hz blinking
only TURBICUBE 20
= glasses dirty or liquids to much colorized
(damping factor > 20 dB)
Note:
The turbidity measuring instruments are calibrated with the internationally specified standard suspension
Formazin
. The indication takes place
thus not in form of the measured light intensity, but as concentration of the
Formazin
calibration suspension. During the measurement of any
liquid this means thus that the liquid concerned causes the same light scattering as the standard suspension of the indicated concentration.
Measured values of other turbidity measuring instruments, which use other calibration suspensions and measuring angle, cannot be compared
directly with those with Formazin calibrated measuring instruments!
