DESCRIPTION
The TURBISWITCHGS5 evaluation unit in conjunction with the associated transducers is an optical turbidity measurement for determining
the solid content in a liquid medium.
The turbidity signal is read out as an adjustable limit value via the evaluation unit.
The turbidity measurement is based on the optical absorption method, i.e. it reacts to light loss due to undissolved solids in the medium. Due to
clocked infrared light, the measurement is insensitive to external light.
If the measured turbidity value is exceeding or below the trigger point value, the output relay in the TURBISWITCHGS5 is actuated in
accordance with the settings.
Attention: Operation of the transducers of the TRUBOMAT series (TT-GS, TR-GS and CP1) at the evaluation unit
TURBISWITCHGS5 is not possible!

DISPLAYS ON THE EVALUATION UNIT
Yellow LEDs: Selected measuring range: 1 LED = LOW / 2 LEDs = MEDIUM / 3 LEDs = HIGH
Blue LED: LED lit: Limit value exceeded; LED off: measurement below the limit
0-100: Selected limit value (%) in the specified measuring range
TR: Receiver malfunction or receiver not connected
TT: Emitter malfunction or emitter not connected
CR: Memory error (perform reset to factory settings)
ST: Default values (after reset to factory settings)
ER: Excessive number of transmission errors during digital transmission
HT: Permissible temperature range of the transducer exceeded
LT: Valid temperature of the transducer underrun
In the case of Measuring cells for piping systems (TURBISWITCHGA…), the green LEDs in the terminal housing of the TT-HDR emitter and
the TR-HDR receiver blink as long as internal measured value processing operates correctly (a continuously illuminated or red LED indicates a
fault).
LIMIT VALUE SWITCHING PERFORMANCE
The blue LED is off: turbidity of the medium is below the selected limit value. The relay for ’’Below limit value’’ is open.
The blue LED is lit: the limit value has been exceeded. The relay for “limit value exceeded” is open.
LIMIT VALUE ADJUSTMENT
Setting range: 3x 0...100% (LOW / MEDIUM / HIGH) by turning the rotary/pushbutton switch.
Note: Switching to the next higher or lower measuring range is accomplished by simply turning the rotary/pushbutton selector.
The selected hysteresis value is automatically skipped in this case. 100% in the LOW range is followed by 0% in the MEDIUM range.
100% in the MEDIUM range is followed by 0% in the HIGH range.
100% in the HIGH range is the highest possible limit value.
0% Low/Med/High 100% Low 100% Med 100% High
Overall Sensing Range
In the LOW range One yellow LED lights up
In the MEDIUM range Two yellow LEDs light up
In the HIGH range Three yellow LEDs light up
The limit value cannot be set to less than or equal to the currently selected reset hysteresis!
DELAY TIME "TD"
Adjustable from 0.1 to 9.9seconds (default value: 0.1second).
RESET HYSTERESIS "HY"
Setting range: 1 to 25% of the selected limit value.
The output relays are not switched back until the measured value decreased below the selected percentage of hysteresis
Reset hysteresis cannot be set to greater than or equal to the currently selected limit value!
The default setting for reset hysteresis is 1%.
TEMPERATURE MONITORING "TP" (TEMPERATURE PROTECTION)
Setting range: on/off
The connected probe is designed for a specific temperature range. If the permitted range is exceeded, this is indicated as an error. If this alarm
function is not desired, temperature monitoring can be deactivated (Off).

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”.

INSTALLING A MEASURING CELL IN A PIPING SYSTEM (IN-LINE) / (Continuation)
To assure a reliable measurement please observe the following:
• The optical windows must be clean!
• The formation of gas bubbles in the medium should be prevented to avoid false measurements!
• The emitter and the receiver must always be aligned with the horizontal axis of the pipe when installed horizontally in order to avoid
incorrect measurements due to deposits on the glass discs (see picture below)!
E R
R
E
• Only a completely filled pipeline guarantees a correct measurement!
• It may be advisable to provide for back pressure by means of restriction, or to install a trap.
• Dried-on residues on the glass discs distort measurements, e.g. after an operating process was in standby.
• It is recommended to include straight pipe distances, upstream and downstream the measuring cell, of at least 3 to 5 times the diameter of
the pipe.
• When mounted in a trap, stop valves or/and drain valve should be installed for easy maintenance and removing the measuring cell.
• Use the supplied mounting kit (key tool and suction cup) in order to remove and install the glass discs. Observe torque! (Torque spanner
Turbiclick 5.7 optionally available, please contact us).
INSTALLING AND CONNECTING THE IMMERSION PROBE (CP2 or CP5)
Installing the immersion probe
The TURBISWITCHCP2 and CP5 transducers are designed as hanging probes or for use with an extension tube.
It can be installed in slurry tanks, basins or open wells.
The probe should be installed so that it can be easily removed for cleaning.
Gas bubbles cause false measurements!
The frequency of cleaning routines depends on operating conditions.
Do not scratch the optics when cleaning the sensors!
The following measuring ranges apply to the TURBISWITCHCP2 and CP5 transducers:
Minimum detectable turbidity in the LOW range: starts at roughly 100...300FAU
Maximum detectable turbidity in the HIGH range: approx. 30000FAU (corresponds to approx. 100g/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

SETTING THE THRESHOLD, LIMIT VALUE AND COMMISSIONING
Adjustment takes place after installation and electrical connection.
If problems arise, see “Troubleshooting”.
All steps must be carried out in chronological order!
Detecting the transition from the clear phase to sludge:
1. Turn the rotary/pushbutton selector on the evaluation unit clockwise as far as it will go until the display indicates 100% in the HIGH range.
3 LEDs light up yellow.
2. Fill the measuring cell with the clear phase or immerse the probe into the clear phase (blue LED is off).
3. Turn the rotary switch anticlockwise (-) until the blue LED lights up.
4. Slowly turn clockwise (+) until the blue LED goes out.
The device now reacts as soon as the medium becomes slightly more turbid.
5. To prevent the TURBISWITCHGS5 from reacting to extremely slight deviations, adjust the switching point a bit further in the clockwise
direction (+) (approx. 5 to 20 %).

SETTINGS THE THRESHOLD, LIMIT VALUE AND COMMISSIONING (Continuation)
Other settings and optimisation:
• If the ascertained limit value is below 10% in the HIGH or MEDIUM range, turn anticlockwise (-) to switch into the LOW range, thus
permitting a more accurate adjustment.
• In order to avoid inadvertent switching due to any brief occurrence of gas bubbles or particles, switching contact delay time (TD) can be
increased to as long as 9.9 seconds.
• Inadvertent switching in the event of switching point fluctuation can be avoided by increasing reset hysteresis (HY).
