The capacitive sensor has a switching output with an adjustable switch point. After successful
teach-in the sensor automatically runs in the normal operating mode. The interval between two
teach operations can be set to any length as required.
NOTE
If a determined switch point is outside of the saved switching interval, the taught
value is rejected. The device indicates a fault and returns to normal operation without
any changes.
Teach in the devices as follows:
Switch point: Medium
present
1
Switch point: Medium
not present
1

Set the switch point centrally between “Medium present” and “Medium not present”: Teach both medium states in sequence.
The TX1-Q20L60 teach adapter is not supplied with the device and must be ordered additionally. To use the teach adapter connect it between the sensor and the connection cable.
9.1 Setting via the teach adapter
“Medium present” teach
➤ Connect the TX1-Q20L60 teach adapter between the sensor and the connection cable.
➤ Specify object/level for switch point.
➤ Press and hold down the pushbutton on the adapter to U
B
for 2…9 s.
➥ If the LED goes out for about 0.5 s and the sensor returns to normal operation, the teach
operation has been successfully completed. In this case, the switch point is 20% below the
capacitance measured in the teach mode.
➥ If the green LED flashes rapidly for about 1 s, the teaching process has failed and must be
repeated.
