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).
