2.6 Activation/Deactivation of the Measuring System
2.6.1 Bi-directional Mode
INFORMATION
In "ERROR" mode, the receiver scans the entire frequency range available to it for interference and internally
evaluates the available frequency bands for their quality.
If a touch probe is activated with a radio-wave signal, then the information is simultaneously transmitted with the
activation signal about which frequency band communication is to be made (best quality).
The transmission is a semi-duplex transmission, i.e. the signal transmission takes place alternately in both
directions.
1. Switching ON the probe:
1.1. Load probe.
1.2. Switch ON signal from machine control to receiver.
1.3. Receiver switches touch probe on by radio-wave signal and transmits the optimum frequency band for
further communication.
1.4. Probe transmits "READY" signals to receiver.
1.5. Receiver transmits "READY" signal to machine control.
1.6. Probe ready to work.
2. Switching OFF the touch probe:
2.1. Machine control sends switch-off signal to receiver.
2.2. The touch probe automatically switches to Standby mode as soon as no transmission confirmation from the
receiver is registered.
